Eco-Fashion Consumption: Cognitive-Experiential Self-
Theory
Chapter 1
Introduction
Fashion provides an enjoyable lifestyle to fashion-conscious consumers but makes
significant costs in environmental and societal terms. Some individuals adopt new styles to
maintain their differentiation, and they continuously focus their interest on acquiring fashion
merchandise; for those consumers, seeking new and unfamiliar products/brands is significant
(Babin, Darden, & Griffin, 1994). However, these fashion products rapidly become
unfashionable, and the wasted clothing ends up in landfills where it pollutes the ground and
water (Payne, 2014). Thus, the concerns in environmentally friendly production and consumption
create conflicting needs and challenges for a society that desires both fashion and sustainability.
To operate efficiently and act responsibly, companies must deliver value to consumers in
a way that maintains and improves consumers’ and society’s well-being (Armstrong & Kotler,
2013). As an increasing number of organizations aspires to “go green,” marketers of established
brands have begun to launch green-brand extensions to reach ecologically and socially conscious
consumers and to enhance the overall brand image (Faisal, 2010). Manufacturers have modified
their product design, development, and sourcing strategies to incorporate environmentally
friendly practices to promote eco-fashion, and both manufacturers and retailers have modified
marketing strategies to better communicate with consumers (Lipson, 2008). For example,
companies have incorporated terms such as eco, green, ethical, natural, organic, and sustainable
in their promotional messages to attract consumers’ attention (Bennie, Gazibara, & Murray,
2010). Eco-products are products that cause minimal harm to people and the environment, reduce
waste, benefit the society, and make the planet a good place to live (Chouhan, Kumar, Sharma, &
Ameta, 2013). In this sense, eco-products are associated with different terms such as green,
ethical, natural, organic, and sustainable products. Many fashion companies, including both
manufacturers and retailers, are developing and marketing eco-fashion to promote ethical
consumption. Accordingly, the terms ethical fashion, eco-fashion, and sustainable fashion have
become popular within the media over the last few years (Bennie, Gazibara, & Murray, 2010).
Eco-fashion is fashion clothing designed for long lifetime use, produced in an ethical and
ecological production system that causes little or no negative environmental or social impacts
(Fletcher, 2008; Niinimaki, 2010). It is made with biodegradable or recycled materials such as
corn fiber and environmentally responsible processes such as dyed in the natural dyes (Fletcher,
2008; Niinimaki, 2010). Eco-fashion is a brand extension strategy that the fashion industry uses
to reduce its environmental and social problems, to enhance its social reputation, and to maintain
high profits (Choi, Liu, Tang, & Yu, 2011). Manufacturers and retailers expect to see that the
brand-extension strategy leads to a reciprocal spillover effect between the extended eco-fashion
and the fashion parent brand (Dwivedi, Merrilees, & Sweeney, 2006; Choi et al., 2011).
Specifically, marketers expect to see that responses toward the fashion parent brand could also be
obtained from its eco-fashion product.
Consumers are increasingly aware of environmental and social issues (Carey &
Cervellon, 2014). Ecologically conscious consumers actually use more eco-products than
consumers who are less ecologically conscious (Lin & Chang, 2012). Consumers continue to buy
eco-products despite facing the realities of a difficult economy, which is supported by the finding
that 35% of American adults would pay more for environmentally friendly products (Mintel
Oxygen Report, 2010) and that 78% of US consumers are willing to pay extra for
environmentally friendly products and prefer green advertisement promoting these products
(Laroche, Bergeron, & Barbaro, 2001). According to Shen, Wang, Lo, and Shum (2012),
consumers’ social and environmental concerns are positively related to their support for social
and environmental friendly businesses and their willingness to pay premium for social and
environmental friendly products.
On the other hand, some consumers perceive eco-fashion products as not fashionable, not
meeting their aesthetic needs and fashion interest (Beard, 2008), and pricy because they pay
more attention to style and price when purchasing the fashion products (Chan & Wong, 2012). In
fact, some American consumers are not willing to pay extra for eco-products because of
insufficient promotion of eco-products for their premium price (Neff & Halliday, 2000), and
consumers do not have a real opportunity to choose eco-fashion because of limited styles and
fewer choices of eco-fashion (Legoeul, 2006). This leads to raising research questions such as
how consumers respond to eco-fashion, whether individual differences influence their responses
toward eco-fashion, and what type of responses contribute to consumer behavioral tendency
toward eco-fashion. Moreover, by exploring individual differences in information processing,
researchers may broaden and strengthen their understanding of how consumer behavioral
outcomes are explained by affective responses and cognitive responses. Therefore, this study
examines the hierarchical relationships among individual differences, responses, and consumer
behavioral tendencies in the eco-fashion context.
This study combines qualitative and quantitative research techniques to address the
research questions. A focus group interview, one of the most frequently used qualitative
techniques (Greenbaum, 2000), is used to select eco-fashion clothing images as visual stimuli
and to decide on the age ranges of the sample. A self-administered online questionnaire, a
quantitative research technique, is used to collect data and test the hierarchical relationships
among individual differences, responses, and consumer behavioral tendencies based on
Bettman’s consumer information processing model (1979) and Epstein’s cognitive-experiential
self-theory (1998).
Both Bettman’s information processing model (1979) and Epstein’s cognitiveexperiential
self-theory (1998) introduce how an individual processes information. Bettman’s information
processing model emphasizes the flow of information in which an input enters into the storage or
process stage, and an individual processes the input information and then makes the accept-reject
decisions based on choice object attributes (i.e., color, price, or weight of a product), external
environmental attributes (i.e., word of mouth or online reviews of a product), and internal cues or
cognitive variables (i.e., risk involving toward a product). Input can be an individual, her activity,
others’ advice, others’ comments or information provided by the environment, a product, or a
service. Storage or process intervenes between input and output. Output indicates the outcome
from the storage or process step. Epstein’s cognitive-experiential self-theory underlines that the
human brain has the capability for extensive parallel processing to carry out multiple operations
such as utilitarian attributes (e.g., materials and price) and experiential attributes (e.g., design and
color) of a product.
The information processing varies among different consumers, and consumer choice is
inherently constructive (Bettman, Luce, & Payne, 1998). Bettman (1979) explained the
individuals’ information processing as a structural concept of the individual consumer
decisionmaking process in his consumer information-processing model. As a processor of
information, the consumer receives a large amount of information externally from the marketer
and the environment, and stores information as a database processed over time from her learning,
experiences, and social influences. With a huge amount of information to which the consumer is
exposed, the processing is difficult and hard to manage. The consumer uses certain simplifying
strategies such as focusing on the most important attribute to make the decision. That is, the
consumer does not process all information together and uses simplifying strategies such as
intervening response system to process information.
The rational and experiential systems operate in parallel and are interactive to determine
human goals, thoughts, and behavior (Epstein & Pacini, 1999). In an eco-fashion consumption
context, the experiential system is associated with consumers’ favorable feelings and experiences
toward fashion, while the rational system is associated with their rational thinking toward
environmental and social issues of the fashion industry. Experiential and rational responses
toward eco-fashion occur simultaneously as well as sequentially and contribute to the consumer
behavioral tendencies regarding eco-fashion. The next section addresses ways to understand
consumers’ responses and their behavioral tendency toward eco-fashion, fashion as a social and
ecological concern, eco-fashion as a brand extension strategy and a niche market, and
cognitiveexperiential responses in eco-fashion consumption. The section also examines the
significance of the study, research objectives, and definitions of concepts and constructs.
Fashion as a Social and Ecological Concern
Fashion is one of the essential arts of civilization. It reflects the culture, the history, and
the social and environmental characteristics of a particular geographical area at a certain time
period (Geczy & Karaminas, 2012). Fashion clothes are colorful; however, production processes
such as dyeing, drying, and finishing utilized to keep the color look fresh and long generate a
high environmental impact, resulting in approximately 20% of global industrial water pollution
(Brito, Carbone, & Blanquart, 2008). To keep the low cost of fashion clothing, fashion industry
causes social issues such as child labor or low wages. The current mode of production in the
fashion industry is unsustainable in the long term because of the negative social and
environmental impacts from the manufacturing processes of apparel. At the same time, the
constant change in fashion styles increases consumption and production, which aggravates these
negative impacts (Gertsakis & Neil, 2011). Many consumers may buy cheaply made fashion
clothes to keep up the latest fashion trend, while the fiber and textile production processes
required to manufacture these cheap fashionable clothes have harmful effects on both workers
and environments in the form of pollution of waterways resulting from using pesticides, dyes,
and chemicals (Heathcote, 2009).
In recent years, sustainability has become a central consideration for the apparel industry,
and it has begun to affect apparel industry strategies, operations, and workforce engagement
(Pookulangara & Shephard, 2013). Sustainability is a broader term regarding products and
services used over a much longer period of time, and it considers social and financial impacts as
well. Sustainability is crucial to companies’ strategies, especially for those that produce goods in
environmentally sensitive business areas such as the fashion industry (Caniato, Caridi, Crippa &
Moretto, 2012). With great concern about environmental issues, companies realize that
trendsensitive fashion typically has the potential to earn high profit but raises ecological and
social issues.
As a result, the fashion industry is gradually implementing more environmentally and
socially responsible practices (Payne, 2014). For example, fashion retailers such as H & M and
NIKE are looking for strategies that incorporate considerations of sustainability in product
designs (Wiese, Kellner, Lietke, Toporowski, & Zielke, 2012). Also, Loomstate
(http://www.loomstate.org) is an apparel company that actively participates in environmental
programs. Consumers purchasing Loomstate T-shirt directly support the company to cleanup
beach, protect wildlife, and upcycle projects.
Eco-Fashion as a Brand Extension Strategy
To achieve sustainable growth in revenue and market share, fashion organizations with
established brands are increasingly launching brand extensions, which include category and line
extensions, to promote eco-fashion consumption (Choi et al., 2011). Category extension occurs
when a parent brand launches new product categories, while line extension occurs when a parent
brand introduces new lines within the same product category (Albrecht, Backhaus, Guraki, &
Woisetschlager, 2013). Different brands adopt different brand extensions, with line extension
more common than category extension. Specifically, line extension reduces overall promotion
costs and risks by introducing product varieties to the eco-fashion area (Choi et al., 2011). For
example, Levi’s, a well-known worldwide American clothing company, extended its product to
the eco-fashion area by developing the Waste Less Jeans made from recycled plastic bottles and
plastic waste under the Levi’s name (Weisbaum, 2013); Puma extended its product lines by
introducing a new collection called InCycle composed of biodegradable or recyclable items
(Pasonlini, 2013); and Gucci, the Italian luxury goods company, launched a new line of
ecofriendly shoes made with biodegradable plastic, targeting both male and female consumers
(Turra, 2012). With these extensions, manufacturers and retailers expect a spillover effect
between the parent brand and its eco-fashion (Dwivedi, Merrilees, & Sweeney, 2006), which
leads to the consumers’ favorable feelings toward eco-fashion.
Challenges of Eco-Fashion
The fashion industry is increasingly launching eco-fashion to promote sustainable
consumption and to achieve sustainable growth in revenue and in market share (Choi et al.,
2011). Despite the effort manufacturers and retailers have made and the widespread attention to
and consumer awareness of sustainability, sales of eco-fashion still represent only a small
fraction of overall demand (Luchs, Naylor, Irwin, & Raghunathan, 2010). Several reasons may
explain the lower sales revenue of eco-fashion. First, the impact of eco-products on the
environment is subtle, difficult to highlight, and indirect, so it takes a long time to foster
consumers’ environmental conservation-generating behavior (Sima, 2014). Further, although
consumers indicate that they are willing to buy sustainable products, they have difficulty in
identifying brands that are truly environmentally friendly and trusting the origin of products and
their performance on environment (Yan, Hyllegard, & Blaesi, 2012). The lack of explicit
information in eco-fashion such as eco-labels and consumers’ confusion about the information of
specific materials and methods used to manufacture eco-fashion impede generating positive
responses to eco-fashion (Tompkins, 2008). In addition, higher prices associated with
environmentally friendly apparel and textiles may be obstacles to purchasing for many
consumers (Fletcher, 2008; Niinimaki, 2010). Also, many consumers consider eco-fashion to be
unfashionable and limited style/less choices, which reduce their purchase interests toward
ecofashion (Carey & Cervellon, 2014).
Manufactures, designers, and retailers must understand what consumers need and expect
from eco-fashion, satisfy their needs, and then build a profitable long-term relationship with
consumers. Therefore, clothes should be produced sustainably and fashionable with a wide
variety of selections as well as suit consumers’ aesthetic needs and fashion interest (Beard,
2008). Specifically, Mintel (2009) found that consumers do not see an environmental aspect of
eco-product as value added and do not want to pay a premium price for the eco-product. Nakano
(2007) found that consumers are not willing to pay over 10% more for sustainable clothing.
Thus, controlling the cost of eco-fashion and promoting the product effectively are important for
eco-fashion. Marketers should tell customers why eco-fashion is worth a higher price and
determine how to best communicate its fashion and ethical attributes to consumers.
Previous Research on Sustainable Fashion
Previous research on sustainable fashion highlights consumers’ preferences toward
fashion, their interest in sustainability, and their purchase intention toward sustainable products.
For example, Gabrielli, Baghi, and Codeluppi (2013) investigated fashion product consumption
habits of consumers with different ages and lifestyles and found that consumers who are under
the age of 35 consider fashion as freedom and those who are over the age of 35 view fashion as
wearing something unusual. Hartmann and Apaolaza-Ibanez (2012) concluded that psychological
benefits such as warm glow, self-expressive benefits, and nature experiences can enhance
consumer attitudes toward green energy brands and increase purchase intention. Similarly, Shen,
Wang, Chris, Lo, and Shum (2012) found that consumers’ beliefs about ethical fashion influence
their support toward socially and environmentally responsible business. A qualitative study of
Birtwistle and Moore (2007) examined how consumers disposed of fashion products and how
clothing can be re-used and recycled. The authors discovered that the increase in fashion
purchasing leads to disposing of garments, and sending them to charity shops or to a recycling
plant. On the other hand, Kim and Damhorst (1998) found that consumers’ environmental
knowledge had a limited relationship with their concern for the environment or environmentally
responsible apparel consumption.
Cognitive-Experiential Responses in Eco-Fashion Consumption
Both affect and cognition are important for information processing of fashion (Hoyer &
Stokburger-Sauer, 2012). Cognitive-experiential self-theory (CEST; Epstein, 1990, 1991, 1993,
1994) proposes two fundamentally different modes of information processing:
intuitiveexperiential and analytical-rational thinking (Epstein, Pacini, Denes-Raj, & Heier 1996).
Experiential and rational system responses are parallel in consumers’ decision making and occur
simultaneously as well as sequentially (Epstein, 1998). The intuitive-experiential process is
automatic, fast, holistic, associationistic, primarily nonverbal, and highly affective. In contrast,
the analytical-rational thinking is analytic, logical, effortful, slow, primarily verbal, and
relatively affect free (Epstein, Pacini, Denes-Raj, & Heier, 1996). “Experiential” individuals
reply on impressions and prefer rapid intuitive conclusions, while “rational” individuals are
willing to engage in careful conscious processing (Hample & Richards, 2014). These arguments
are similar to those of prior researchers in that affective response is a reaction toward whether an
object is pleasant, attractive, valuable, likable, or preferable (Russell & Snodgrass, 1987), and
that rational responses such as knowledge, opinions, beliefs, and thoughts are produced from
memory in response to the environment (Fishbein & Azjen, 1975).
In an eco-fashion consumption context, consumers can be emotionally driven by the need
to adopt new styles to maintain their differentiation and interest in acquiring fashion
merchandise. On the other had, consumers can be logically driven by their concerns about
environmental and social impacts that are caused by the fashion production process. Their
favorable feeling toward fashion and their awareness of environmtal and social problems toward
fashion production may create desire for eco-fashion. In sum, consumers feel experientially and
think rationally when engaging in consumption activities such as eco-fashion consumption (Shiv
& Fedorikhin, 1999).
Consumption of fashion products leads to experiential responses that are fun, pleasure,
and excitement to consumers (Khan, Dhar, & Wertenbroch, 2005). Moreover, consumers in the
developed world are well aware of the environmental impact of the present industrial production
and thus have an increasing interest in ecologically and socially conscious products, and this
interested is associated with rational responses (Lin & Chang, 2012). Eco-fashion with ethical
and fashion attributes can satisfy consumers’ desire for fashion products and reconcile their
concerns in environmental and social issues. Therefore, experiential and rational system
responses provide strong explanations and predictions of individual behavior toward eco-fashion
(Epstein, 2003).
The Significance of the Study
To effectively promote eco-fashion, marketers need to understand the consumer purchase
decision process. To do so, this study examines relationships among consumers’ emotion-driven
dispositions (need for variety and fashion interest) and logic-driven dispositions (ecological
consciousness and social consciousness), their cognitive and experiential responses associated
with eco-fashion, and the corresponding consumer behavioral tendencies toward eco-fashion
(purchase intention and willingness to pay more). Within the hierarchical framework of
consumers’ individual differences (their dispositions), their responses, and their behavioral
tendencies, the research model explains consumers’ information response system from two
perspectives (i.e., experiential system response and rational system response), and it examines
the effects of individual differences on responses, the effects of cognitive responses on affective
responses, and the effects of responses on consumer behavioral tendencies.
The CEST has been widely used in different studies (Akinci & Sadler, 2013; Hogarth,
2002; Mischel & Shoda, 1995; Shiv & Fedorikhin, 1999; Sloman, 1996). Akinci and Sadler
(2013) found that using CEST to assess intuitive (experiential) and rational (analytical) cognitive
styles in workplace performance is valid. For example, employee selection and performance
appraisal could use the measures of intuition (experientiality) and analysis (rationality) by
matching individuals to different tasks. Hogarth (2002) argued that there is a trade-off between
the intuition and the analysis when people make decisions. Specifically, the greater the
complexity a task exhibits in analytical terms, the less likely a person will both know the
appropriate formula and apply it correctly. According to Sloman (1996), people behave in a
rational manner by using cognition to guide them, while they follow their experiential system
response by allowing feeling to lead them. Individuals differ in reacting to cognitive and
affective information responses and different types of cognitive and affective process can
generate different behavior among individuals (Mischel & Shoda, 1995). However, no consumer
researcher has investigated these relationships in eco-fashion consumption by using
cognitiveexperiential self-theory. To address this issue, the current study applies the CEST to
explain how humans’ two fundamental information processing systems─a rational system and an
experiential system─work in consumers’ eco-fashion consumption.
This study will offer several contributions to manufacturers, designers, and retailers of
eco-fashion. First, this study will determine whether emotion-driven dispositions (i.e., fashion
interest and need for variety) impact affective responses and eventually purchase intention and
willingness to pay more toward eco-fashion and whether logical-driven dispositions (i.e.,
ecological consciousness and social consciousness) influence cognitive responses and eventually
purchase intention and willingness to pay more toward eco-fashion. In addition, this study
attends to determine whether cognitive-affective response approach can be applied to the
ecofashion context. The findings may assist eco-fashion marketers to enhance consumers’
affective responses and cognitive responses toward eco-fashion, increasing consumers’ purchase
intention toward eco-fashion, and generating their long-term willingness to pay more for eco-
fashion. The findings also will help designers add ethical attributes such as fair trade, low impact
dyes, or Made In USA to eco-fashion and design a variety of stylish eco-fashion to appeal to a
large number of consumers who understand and recognize the benefits of eco-fashion and willing
to purchase and pay premium price for eco-fashion.
Research Objectives
Based on the discussion related to ecological and sociologic issues in fashion and
characteristics of eco-fashion, this study attempts to find ways to promote eco-fashion. The
purpose of this study is to examine the hierarchical relationships among individual differences,
consumer responses and consumer behavioral tendencies in an eco-fashion consumption context
by applying the cognitive-experiential self-theory. Specifically, the objectives of this study are
to:
1. Investigate the effects of consumers’ emotion-driven dispositions (fashion interest and
need for variety) on their affective responses toward eco-fashion.
2. Investigate the effects of consumers’ logical-driven dispositions (ecological
consciousness and social consciousness) on their cognitive responses toward eco-fashion.
3. Explore the effects of consumers’ cognitive responses on their affective responses toward
eco-fashion.
4. Explore the effects of consumers’ cognitive and affective responses on their eco-fashion
consumption behavior tendencies (purchase intention and willingness to pay more).

Literature Review
Chapter one introduced the background, significance, objectives of the study, and
definitions of concepts and constructs. The main objectives of this study are to determine (a) the
effects of consumers’ emotion-driven dispositions (fashion interest and need for variety) on their
affective responses toward eco-fashion, (b) the effects of consumers’ logical-driven dispositions

eco-fashion, and (d) the effects of consumers’ cognitive and affective responses on eco-fashion
consumption behavior (purchase intention and willingness to pay more). To achieve these
objectives, Chapter two provides an overview of eco-fashion, accompanied by the theoretical
background (information processing model and cognitive-experiential self-theory) and the
conceptual model development. Following this, research hypotheses are proposed depicting the
relationships among consumers’ dispositions (fashion interest, need for variety, ecological
consciousness, social consciousness), their responses (affective response and cognitive
responses), and their behavioral tendency (purchase intention and willingness to pay more).
Overview of Eco-Fashion
Eco-fashion refers to fashion clothing designed for long lifetime use, produced in an
ethical and ecological production system that causes little or no negative environmental or social
impacts. Eco-fashion is made with biodegradable or recycled materials such as corn fiber and
environmentally responsible processes such as natural dyes. It is important to note that these
production processes may result in higher prices for eco-fashion products (Fletcher, 2008;
Niinimaki, 2010). Eco-fashion is devoted to the clothing made with eco-fabric such as renewable
materials that can accomplish consumers’ need to try out new technologies representing a
different life experience (Aaijaz & Ibrahim, 2010). With the growing concern about the
environment and the natural world, eco-products can start a trend and benefit consumers,
society’s well-being, and eventually companies (Kaufman, 1999).
Sustainability is a broad term regarding products and services used over a much longer
period of time and considers the influence of social, environmental, and economic impacts as
well. As a business strategy, sustainability is important for the fashion industry as it endeavors to
develop and market eco-fashion to promote ethical consumption. The history of sustainability
traces back to human ecological systems. The term “ecology” was first used in the 1980s. A
more general term “environmental” emerged in the 1990s and at the same time the word “green”
fell into the history. Many eco-products are made from natural fabrics like silk, linen, hemp, and
wool, made by designers who use ethical and environmentally friendly manufacturing processes
(500eco, 2013). To enhance social reputation and maintain high profits, the fashion industry
applies a brand extension strategy to eco-fashion (Choi et al., 2011). Firms with established
brands are increasingly developing green brand extensions, either as line extensions or category
extensions (Chatterjee, 2009). Category extension happens when a parent brand launches new
product categories, while line extension happens when a parent brand introduces new lines
within the same product category (Albrecht et al., 2013). These extensions offer the types of
clothing designed and manufactured to maximize benefits to people and society while
minimizing adverse environmental impacts (Joergens, 2006).
Consumers buying eco-fashion clothing make consumption decisions differently from
consumers in other consumption sectors do (Chan & Wong, 2012). For example, consumers in
the food sector express care and show commitment to ethical consumption because food directly
influences their health and their right choice reflects the possibility of a direct benefit to them.
On the other hand, consumers in the fashion sector show less commitment to eco-consumption
because a non-ethical choice does not directly affect their health (Joergens, 2006). For
ecoproducts, various product cues such as the colors of the product’s packaging and content are
commonly used to convey their eco-friendly status (Lin & Chang, 2012). In demonstrating
ecofashion consumption behavior, a consumer may choose items based on attributes associated
with less harm to the environment and society or based on considerations of energy and materials
used for production, packing, transportation, and distribution (Sonnenberg, Jacobs, & Momberg,
2014).
Theoretical Background: Information Processing Model (IPO)
Humans respond to information, and information processing is the change of information
to describe everything that happens in the universe. Bettman’s information processing model
(1979) indicates the flow of information from input to storage or process and then output. Input
is something that is put into the system for some type of use and could be an individual, her
activity, others’ advice, others’ comments or information provided by the environment, a
product, or a service. Storage or process is the step to process information and mediate between
input and output. Output is the outcome, resulting from the storage or process step. From a
consumer input perspective, individual difference, search activity, type of involvement, task
definition, and resources that a consumer brings to the exchange transaction may influence her
information processing and eventually impact her behavior output (Bettman, 1979). Various
environment and consumer inputs are processed by an intervening response system that generates
output consequences, criteria, and learning effects (Holbrook & Hirschman, 1982).
Intervening response system such as a rational system or an experiential system refers to the
consumer responses that mediate between various sorts of inputs and outputs (Holbrook, 1995).
The consumer information process is shown in Figure 1, which allocates a consumer as
central to a host of information processing activities. The consumer is exposed to a large amount
of information daily, and she stores information and processes the information over time from
her learning, experiences, and social influences. It is hard for her to process and manage such a
large amount of information. Thus, the consumer does not process all information together and
uses certain simplifying strategies such as making decisions based on routine thinking or
focusing on the most important attribute to make the decision.
Further, the human brain has the capability for extensive parallel processing to carry out
multiple operations such as seeing utilitarian attributes (e.g., materials and price) and experiential
attributes (e.g., color and design) of a product (Epstein, Seymour, & Pacini, 1999). For example,
when a product’s functional features are inputs, the intervening response system processes the
product’s utilitarian information based on its features and then leads to the consumer behavioral
tendency such as purchasing the product or obtaining more information about the product. When
a product’s experiential features are inputs, an individual’s affective responses could be
generated by those features and then lead to the consumer behavioral tendency. In sum, humans
operate by two fundamental information-processing systems that are a rational system and an
experiential system (Epstein, 1990, 1991, 1993, 1994, 1998, 2003).
Figure 1. Consumer Information Processing Model
Theoretical Background: Cognitive-Experiential Self-Theory (CEST)
Originated from Freud’s primary and secondary theory (Freud, 2007), CEST (Epstein,
1990, 1991, 1993, 1994, 1998, 2003) proposes that humans operate by two fundamental
information-processing systems: a rational system and an experiential system. The experiential
and rational systems operate in parallel and are interactive. The intuitive-experiential process has
been variously referred to as automatic, fast, holistic, associationistic, primarily nonverbal, and
highly affective, while the analytical-rational thinking is assumed to be analytic, logical,
effortful, slow, primarily verbal, and relatively affect-free (Epstein, Pacini, Denes-Raj, & Heier,
1996). The experiential system responses may give rise to affective reactions; the rational system
responses are likely to drive cognitive reactions; and together they perform task, achieve goal,
and conduct behavior (Epstein, 1998, 2003; Novak & Hoffman, 2009).
As shown in Figure 2, experiential system responses (affective system responses) can be
associated with cognitive appraisal (rational system responses), and eventually the
analyticalrational system responses can lead to a behavior outcome (goals, thoughts, &
behaviors).
Furthermore, cognitive appraisal (rational system responses) can be related to affective responses
(affective system responses), and the intuitive-experiential system responses can lead to a
behavior outcome (goals, thoughts, & behaviors).
Figure 2. Cognitive-Experiential Self-Theory
Humans operate by two fundamental information-processing systems that are a rational
system and an experiential system. Their goals, thoughts, and behavior are a joint function of the
two systems (Epstein, 1998, 2003; Epstein, Pacini, & Denes, 1996). The intuitive-experiential
systems of human psychology have been labeled as primary (Freud, 2007), intuitive (Hogarth,
2002), impulsive (Strack & Deutsch, 2004), automatic (Bargh, 1989), heuristic (Chaiken, 1980),
and implicit (Koestner, Weinberger & McClelland, 1991), while the analytic-rational systems
have been labeled as secondary (Freud, 2003, 2007), reflective (Strack & Deutsch, 2004),
deliberative-effortful-intentional-systematic (Bargh, 1989; Chaiken, 1980), and explicit
(Koestner, Weinberger & McClelland, 1991).
Freud’s (2003, 2007) primary process and secondary process system theory posits that
there exist two fundamentally different kinds of mental processes (i.e., primary process and
secondary process). The primary process occurs in the present tense and is unable to delay
pleasure, and it is dominated by the pleasure principle. The secondary process includes the
thinking and reasoning ability that represents the past, present, and future. The secondary process
is controlled by the ego that focuses “I” and based on the reality principle. According to Freud
(2007), the primary process is called “primary” because it comes first in humans. The secondary
process occurs later in development and modifies primary process thinking because sometime
humans must be rational to get what they want. In other words, the primary process thinking is
dominated by the pleasure principle, while secondary process thinking is controlled by the ego
and based on the reality principle. In an eco-fashion consumption context, primary process is
related to consumers’ pleasure toward fashion, and their secondary process is associated with
environmental and social problems toward fashion production. Further, consumers’ favorable
feeling toward fashion and their awareness of environmental and social problems relating to
fashion production may contribute to their desire for eco-fashion.
According to Hogarth (2002), people can make decisions through two systems that are
tacit (intuitive) and deliberate (analytic). Tacit (intuitive) system is the part that lies below the
surface (of consciousness) and individuals have quite limited access to it. Deliberate (analytical)
system lies above the surface and can be made explicit. The essential difference between tacit
(intuitive) system and deliberate (analytical) system is cognitive effort that is related to the level
of processing. Greater cognitive effort leads to greater recall, which in turn leads to a greater
tendency to integrate the task environment. The tacit system is triggered by stimuli that are
available in the environment, whereas deliberate thought can be controlled by the individual. In an
eco-fashion consumption context, consumers’ tacit system may be triggered by stylish fashion
merchandise, and their deliberate thought may be generated and directed by environmental and
social problems of fashion production. Moreover, consumers make eco-fashion decisions through
the tacit (intuitive) system to satisfy their desires for fashion products and through the deliberate
(analytical) system to reconcile their concerns regarding environmental and social issues.
According to Strack and Deutsch (2004), social behavior is the effect of the operation of
two distinct systems of information processing: a reflective system and an impulsive system. In
the reflective system, behavior is elicited as a consequence of a decision process. In the
impulsive system, behavior is elicited without the person’s intention or purpose and is influenced
by motivation and the information available in the environment. The reflective system and the
impulsive system operate in parallel. Strack and Deutsch (2004) assumed that information
entering the storage or process stage will always be processed in the impulsive system. In other
words, the impulsive system is always engaged in processing information. In an eco-fashion
consumption context, consumers’ reflective system is activated when they think about
environmental and social impacts caused by the fashion production process, while their
impulsive system is activated when they process information about fashion merchandise. The
reflective system and the impulsive system operate in parallel, which determines consumers’
behavior outcome toward eco-fashion.
In the work of Chaiken (1980), a systematic view of persuasion emphasizes detailed
information processing of message content and reveals considerable cognitive effort in the
assessment of the validity of the message. When recipients receive information relating to
personally important topics or when they feel that their opinion judgments have important
consequences for themselves or for others, they employ a systematic processing strategy. In
contrast, a heuristic view of persuasion focuses on simple rules to process messages and shows
relatively little effort in judging messages. Heuristic information processing may involve the use
of general rules developed by individuals through their past experiences and observation. In an
eco-fashion consumption context, a heuristic view may be used when individuals are simply
attracted by a variety style of eco-fashion, while a systematic view may be used when
individuals’ social benefits derived from products are weighted more highly than their personal
benefits.
As proposed by Bargh (1989), an automatic thought process is unintentional, involuntary,
effortless, autonomous, and happening outside of awareness. Specifically, it occurs without the
need for any intention, without any awareness of the operation of the process, and without
interfering with other thought processes. The conscious or controlled process is under the flexible
and intentional control of the individual. Specifically, an individual is consciously aware of and
constrained by the available cognitive resources. In an eco-fashion consumption context, an
automatic thought process may be involved in satisfying an individual’s desire to maintain their
differentiation and interest in acquiring fashion merchandise, while a conscious or controlled
process may be involved in satisfying an individual’s desire to reconcile their concerns regarding
environmental and social issues.
Koestner, Weinberger and McClelland (1991) proposed that there are two independent
motivational systems: those related to implicit needs and explicit (self-attributed) needs. The two
types of motivational systems (implicit and explicit) are connected with two kinds of situational
factors (task-intrinsic and social-extrinsic), which influence performance. The implicit system is
more likely to be regulated by intrinsic factors in performing an activity. The explicit system is
more likely to be influenced by variations in the social context and is driven by a desire to
perform socially valued achievement activities. In other words, extrinsic social factors tend to
combine with a person’s explicit self-attributed achievement motive to influence activities,
whereas task-intrinsic factors tend to combine with a person’s implicit needs to influence
performance. In an eco-fashion consumption context, the implicit system may be influenced by
intrinsic factors such as favorable feeling regarding fashion, while the explicit system may be
driven by individuals’ desire to engage in ecologically and socially responsible activities.
Therefore, consumers’ desires for fashion products and their concerns regarding environmental
and social issues can be satisfied by eco-fashion products.
Assumptions of CEST
CEST has three assumptions. The first assumption is that people process information by
two independent, interactive conceptual systems: a preconscious experiential system and a
conscious rational system. The second assumption is that the experiential system is fast and
emotion-driven, while the rational system is slow and logic-driven. In other words, the
experiential system is affective in nature and is associated with rapid processing; the rational
system is cognitive in nature and relates to a deliberative processing. The third assumption is that
four basic needs ─ “pleasure principle,” “need to maintain the stability and coherence of a
person’s conceptual system,” “need for relatedness,” and “need for self-esteem”─ are equally
important (Epstein, 1998).
The “pleasure principle” refers to the desire to maximize pleasure and minimize pain
(Freud, 2007; Epstein, 1998). The “need to maintain the stability and coherence of a person’s
conceptual system” means that people have interests to maintain their basic beliefs (Epstein,
1998). The “need for relatedness” refers to the feeling of belonging and the need to feel
connected to others (Epstein, 1998; Bowlby, 2008). The “need for self-esteem” refers to the need
to maintain and enhance the positive self-concept (Epstein, 1993, 1998). All needs are
fundamental in the sense, and CEST considers the four basic needs as equally basic (Epstein,
1998).
The context of individuals’ eco-fashion consumption is related to CEST’s four basic
needs ─ the pleasure principle, the need to maintain the stability and coherence of a person’s
conceptual system, the need for relatedness, and the need for self-esteem. Individuals adopt
fashionable clothing to satisfy their pleasure needs, and at the same time they want to minimize
the pain associated with possible harmful impacts caused by the production of fashion on the
society and the environment (illustrating the pleasure principle). To satisfy their desire to feel
belonging and their need to feel connected to others (showing the need for relatedness),
individuals adopt new styles in fashion merchandise in order to maintain their relatedness.
Further, individuals are aware of the environmental and social issues caused by the process of
production of fashion clothing and care about the environment and members of the society
(showing the need to maintain the stability and coherence of a person’s conceptual system). To
balance their cognition (ethical concern) and affect (fashion needs) needs, consumers adopt
ecofashion to make themselves feel good and to be esteemed by others, which increases their
positive self-concept (showing their need for self-esteem).
The Cognitive-Affective Response Approach
Both affect and cognition are important for information processing in the fashion area
(Hoyer & Stokburger-Sauer, 2012). Literature has been developed on whether consumers first
experience emotional feelings or cognitive thoughts when they encounter an environment. Some
researchers argued that affect is precognitive in nature, which occurs without any cognitive
process and therefore proceeds cognition (Hoch, & Loewenstein, 1991; Verplanken, Hofstee, &
Janssen, 1998; Zajonc, 1984), while other researchers argued that cognitions precede affective
reactions (Lazarus, 1984; Oliver, 1980, 1981; Compeau, Grewal, & Monroe; 1998).
The emotion–cognition approach suggests that affect precedes cognition. For example,
Verplanken, Hofstee, and Janssen (1998) demonstrated that individuals respond more rapidly to
their feelings than to their cognition. Lavine, Thomsen, Zanna, and Borgida (1998) found that an
individual has a spontaneous affect-based reaction when encountering a new person, even before
acquiring any information about the personal qualities of that person.
On the other hand, Compeau, Grewal, and Monroe (1998) found affective responses
mediate the influence of cognitive responses on consumers’ subjective evaluation (perceptions of
quality). Lazarus (1991) further found that an individual cannot have an emotional reaction to a
stimulus when a cognitive appraisal is missing. Lin (2004) stated that when consumers enter an
environment, they are constantly collecting and retrieving information within the environment to
create an overall mental picture in their minds, which leads to an affective evaluation. Therefore,
the cognitive-affective response approach is strongly supported.
Emphasizing only the affective responses of eco-fashion is not enough because
emotiondriven behaviors are typically short in duration (Cohen, Pham, & Andrade, 2008), and
emotiondriven purchases such as impulse buying can generate hedonic feeling but cause high
cognitive dissonance or regret (George & Yaoyuneyoung, 2010). The term cognitive dissonance
refers to discomfort caused by contradictory beliefs or ideas and is related to a situation
involving conflicting attitudes, beliefs, or behaviors (Armstrong & Kotler, 2013). Cognitive
dissonance may occur when some consumers have doubts about the ecological and social
benefits of ecofashion, when those consumers view the eco-fashion as pricy, and when they
consider that ecofashion products do not meet their aesthetic needs.
As such, focusing on only cognitive responses of eco-fashion is not enough because
consumers want to experience a variety of styles or new designs for fashion products. When
individuals’ social benefits of products are weighted higher than personal benefits, their
consumption behaviors are more likely to be driven by a logic think process, which reduces their
positive affective experience. By reflecting the need to reduce the cognitive dissonance of
ecofashion purchase and to enhance the positive feeling of the purchases toward eco-fashion, this
study will apply cognitive-affective responses.
Even though the IPO and CEST provide strong explanations for an overall prediction of
individual behavior, it has not been used in the eco-fashion consumption context. Recognizing
this research gap, this study examines the information processing model by applying IPO and
CEST to understanding hierarchical relationships among individual differences, experiential and
rational system responses, and consumer behavior tendencies. The theoretical framework, shown
in Figure 3, incorporates information processing system cognitive-experiential self-theory
(Epstein, 1978) into the information-processing model (Bettman, 1979).
Proposed Research Model
The main objectives of this study are to determine (a) the effects of consumers’
emotiondriven dispositions (fashion interest and need for variety) on their affective responses
toward eco-fashion, (b) the effects of consumers’ logical-driven dispositions (ecological
consciousness and social consciousness) on their cognitive responses toward eco-fashion, (c) the
effects of consumers’ cognitive responses on their affective responses toward eco-fashion, and
(d) the effects of consumers’ cognitive and affective responses on eco-fashion consumption
behavior (purchase intention and willingness to pay more). The proposed research model is
shown in Figure 4. In terms of an information-processing view of CEST, the study tests how
individual differences influence their experiential system responses and rational system
responses as well as the effects of their responses on consumer behavioral tendencies. Also, the
study tests the effects of consumers’ cognitive responses on their affective responses toward eco-
fashion.
Figure 3. Theoretical Framework
As mentioned above in the theoretical background of CEST, this study applies
cognitiveaffective response approach based on CEST. Consumers in the western society live in a
saturated market with overwhelmed choices beyond their needs (Thackara, 2006). On the one
hand, individuals want to look good, follow trends and get admiration from others (Niinimaki,
2010), which are often related to owning the latest trendy clothes. On the other hand, individuals
are conscious toward environmental and social issues generated by fashion clothing production
process. By understanding the positive impacts of eco-fashion on the environment and society in
a way that protect limited amount of resources and benefit members of society’s well-being,
consumers will have positive affective responses toward eco-fashion. Hence, it can be assumed
that affective system responses arise with a cognitive appraisal.

Review of Literature
Individual Differences: Need for Variety, Fashion Interest, Ecological Consciousness, and
Social Consciousness
Consumers who are faced with a variety of situations show different processing skills
(Childers et al., 1985). Individuals who like to adopt new styles to maintain their differentiation
and those who continuously focus their interest on acquiring fashion merchandise are
emotiondriven, while individuals who are ecologically and socially conscious about the human
impact on the enviornment, the benefits of societal members, and the fashion industry production
process are logic driven. By exploring individual differences in information processing,
marketers may broaden their understanding of how individual differences influence their
intuitive-experiential and analytical-rational thinking processes (Bettman, 1979; Childers et al.,
1985).
Need for Variety and Fashion Interest
The term eco-fashion refers to the clothing made from eco-fabric such as biodegradable
or renewable materials that can meet consumers’ needs to try out new or different products
(Aaijaz & Ibrahim, 2010). Consumers generally have a tendency to seek variation (Simonson
1990), especially in relation to hedonic products such as restaurant food, music, leisure activities,
and fashion products (Ratner, Kahn, & Kahneman, 1999). Need for variety has been defined as a
person’s tendency to switch away from a choice made on a previous occasion (Kahn, Kalwani, &
Morrison, 1982; Ratner et al., 1999). According to McAlister and Pessemier (1982), direct and
derived determinants drive consumers’ need for variety. Direct determinants include
interpersonal and intrapersonal motives.
In interpersonal contexts, consumers have a desire to appear different and unique,
motivating them to make choices different from those of other consumers (Ariely & Levav,
2000). As Kim and Drolet (2003) argued, consumers show variation in their choices to
differentiate themselves from others. In addition, a few intrapersonal mechanisms lead
consumers to seek variety. First, consumers become satiated, at least temporarily, with a specific
product if they consume the product repeatedly (Coombs & Avrunin 1977). Another
intrapersonal mechanism of need for variety is a cognitive need for stimulation (Berlyne, 1970),
novelty, change or curiosity (Venkatesan, 1973; Raju, 1980). Consumers can choose products
they have not consumed recently to increase their level of stimulation (Faison, 1977;
Venketesan, 1973). Finally, consumers seek variety because they have not found a product that
features all the attributes they need (Huber & Reibstain, 1978) or they need a balance of
attributes to maximize utility (Farquhar & Rao, 1976). Generally, consumers seek variety
because they believe they can get more pleasure from switching than from repeating their choices
(Ratner, Kahn, & Kahneman, 1999).
Derived determinants include multiple needs and changes in the choice problem. The
multiple needs include the existence of multiple users (e.g., different members in a household
may have different needs), multiple situations (e.g., the social context of consumption, the
location of consumption, time constraints on consumption, the quantity consumed, emotional
reactions) (Laurent, 1978; McAlister & Pessemier, 1982), and multiple uses. Changes in the
choice problem include changes in the feasible alternatives (e.g., new products are launched and
old ones are discontinued), changes in tastes, or changes in the constraints governing choice
(e.g., a sudden change in wealth, time, or energy).
Eco-fashion is a growing design philosophy, and it comprises fashion clothing designed
to reduce social and environmental impacts, from the growth of its fibers to its use and disposal.
Consumers’ fashion interest and need for variety can be fulfilled by the assortment of products
and services provided by manufacturers, wholesalers, and retailers. The variety of fashion
clothing offered by retailers provides a sufficient source of particular styles to meet a consumer’s
need for differentiation and to satisfy her interest in fashion (Gabrielli, Baghi, & Codeluppi,
2013). Consumer behavior is influenced by psychosocial needs that can be personal
(experiencing novelty and change) or social (being viewed as up-to-date and stylish).
Specifically, when a person feels bored with her appearance, she starts to look for fashionable or
stylish products to satisfy her needs (Arnold & Reynolds, 2003; Law, Zhang, & Leung, 2004).
Therefore, consumers may choose particular products/brands not only because they provide
functional benefits but also because the products can fulfill their psychological needs, such as
need for variety (Kim, Forsythe, Gu, & Moon, 2002).
As for the experiential system, experiencing new, unfamiliar, and fashion products can
generate affective responses (Babin, Darden, & Griffin, 1994). In Arnold and Reynolds’ (2003)
study, a significant number of female and male customers reported that they shop to keep up with
the latest trends, to satisfy their curiosity, or to resolve the boredom associated with another
brand. Consumers are willing to learn about new trends and keeping informed about the latest
trends in fashion, styling, or innovations. These psychosocial needs may enhance consumers’
experiences, which in turn yield affective responses. Fashion interest reflects consumers’
attention toward fashion or their interest in fashion clothing (Chung, 2012). Consumers who have
a strong interest in fashion enjoy shopping for clothing and adopt new apparel products earlier
than other consumer groups (Gam, 2011). By offering eco-fashion containing both ethical and
fashion attributes, designers, manufacturers, and retailers try to capture consumers’ fashion
interest and foster their preferences toward the brand (Choi et al., 2011).
Ecological Consciousness and Social Consciousness
Consumers differ in the extent of their concerns about the environment, the natural world,
and social issues (List, 1993). Consumers who care about the environment and read eco-labels
show a strong sense of environmental responsibility as evidenced by their efforts to protect and
preserve the environment (Alsmadi, 2012). To satisfy their green beliefs and follow ethical
standards, eco-minded individuals have many ways to pursue their environmental interests,
including buying eco-products, basing their personal consumption decisions on the product’s
sustainability, and altering their behaviors in accordance with their green beliefs (Cho, Thyroff,
Rapert, Part, & Lee, 2013). Environmental concern is positively related to purchase intention.
Specifically, those who have high levels of environmental consciousness are willing to purchase
products and services that have a positive impact on the environment (Chang, 2012; Roberts,
1996; Gam, 2011; Zinkhan & Carlson, 1995). Eco-products such as eco-fashion provide
environmental, social, and economic benefits to protect the earth and mankind, and eco-labeled
products would help consumers identify eco-products (Ferguson, 2014).
Socially responsible consumer behavior is associated with societal concerns and
ecological considerations (Robert, 1995). The key social concerns are related to forced labor, low
wages, excessive hours of work, discrimination, health and safety hazards, psychological and
physical abuse, lack of awareness of workers’ right, and lack of worker representation in
negotiations with management (Kozer & Connel, 2012). Socially conscious individuals have
been found to take active roles within their communities for social, political, and charitable
causes (Hainmueller, 2012). Socially responsible consumers purchase products and services that
they perceive have a positive or less negative impact on the environment, and use their
purchasing power to express current social concerns (Kozar & Connell, 2013).
Socially conscious consumers who care about fair wages and work conditions tend to
help provide better living conditions for other people and live up their altruistic values of
“equality” and “social justice” (Jägel et al., 2012). Those consumers think about ways to improve
the quality of life in society and want to have a positive impact on others’ lives by buying ethical
clothing (Broker, 1976). Their purchase decisions lead the way to improve the quality of life in
society. Because socially conscious consumers are more likely to recognize the needs of others in
the society, societal concerns such as the fair trade and made in USA and ecological
considerations such as concerns about pollution are more likely to generate their cognitive
responses. Therefore, social conscious consumers are more likely to purchase eco-products
(Anderson & Cunningham, 1972; Gam, 2011).
Affective and Cognitive Responses
Responses are reactions to an event or situation such as an answer to a question or any
behavior resulting from a stimulus such as behavioral reactions of consumers toward a store
environment (Bagozzi, 1986). Affect is how an individual feels and is a non-conscious
experience of intensity (Shouse, 2005). Affect shows an individual’s feelings toward an object,
which will be favorable, unfavorable, or neutral (Fishbein & Azjen, 1975). The terms affect and
emotion appear to be used interchangeably; typical categories of emotion include rage, hate, joy,
and sadness (Havlena & Holbrook, 1986; Lacher & Mizerski, 1994). An affective response is the
emotional response to a situation such as the feeling of pride (Cohen, Pham, & Andrade, 2008).
Product sensory cues such as color, style, aroma, and flavor positively influence affective
responses, and the availability of sensory stimuli is important to develop affective responses
(Compeau, Grewal, &and Monroe, 1998). Further, some affective responses are more
immediate, take little cognitive effort, and are direct responses to environmental input
(Compeau, Grewal, & Monroe, 1998).
Cognition concerns what an individual knows about an object. Cognition is the sum of
what is known, represents an individual’s thoughts, and is the process by which input is
transformed, reduced, elaborated, stored, recovered, and used (Fishbein & Azjen, 1975;
Kitayama, Duff, Kawamura, & Larsen, 2003). Cognitive responses usually rely on consumers’
own personal experiences or mental images rather than on what they see (Wright, 1980).
Cognitive responses are related to individuals’ thinking when they listen to messages of others
and when they read, watch TV, listen to the radio, or surf the Internet (Dasgupta, 2009).
Cognitive responses can also be thoughts generated in response to persuasive communication
(Petty, 1981). Thus, a cognitive response may be message relevant (Petty & Cacioppo, 1979). If
individuals are very interested in the topic, they will elaborate their cognition. If the messages are
irrelevant to individuals or they do not have related knowledge or experience, they will have
limited cognitive responses.
Consumer Behavioral Tendencies: Purchase Intention and Willingness to Pay
More
Purchase intention is the consumer tendency to purchase products or services (Yoo &
Donthu, 2001). In other words, it measures the consumer’s plan to buy particular goods or
service sometime in future. Fishbin and Ajizen (1975) claim that the single best predictor of a
person’s behavior is the measure of her intention to do that behavior. Willingness to pay more
takes into account the price factor and refers to an individual’s willingness to pay more for a
good or a service compare to the occasion purchase (Bower, Saadat, & Whitten, 2003). For
example, the product or the service may contain certain attributes such as ethical attributes that
consumers need. Consumers who have positive feeling toward firms’ supporting society’s
wellbeing would be willing to switch brands to and purchase products from the firms (David,
Kline, & Dai, 2005). Those consumers are willing to pay a price premium for various types of
ecoproducts marketed by the firms. For example, Keurig estimated that American consumers are
willing to pay a 9% price increase of green coffee and cocoa (Keurig Green Mountain, Inc.,
2014). As another example, ethical consumers are willing to pay more when buying a product
that involves certain ethical issues such as human rights, labor conditions, animal well-being, and
environment (Pelsmacker, Driesen, & Rayp, 2005).
Research Hypotheses
Consumers’ inputs such as individual differences are processed by a cognitive and
affective response system, which activates outcomes such as goals, behavior, and plans (Hample
& Richards, 2014). Based on this viewpoint, five main research hypotheses, shown in Figure 5,
are proposed to test relationships among individual differences, responses, and consumer
behavioral tendencies.
Individual Differences and Responses
Individuals differ in how they process information. Cognitive-experiential self-theory
shows that individuals adopt rational and experiential thinking styles to process information
(Novak & Hoffman, 2009). Individuals’ emotional responses may be evoked when they consider
hedonic products such as movies, vacations, and fashion clothing (Hirschman & Holbrook,
1982), while rational responses may be generated when individuals analyze information
(Epstein, 1994).
Figure 5. Research Hypotheses
Individual differences such as personality, intelligence, memory, age, ego strength, and
gender have been found to influence the results of cognition such as ethical beliefs and
judgments (Haines, Street, & Hainess, 2008). These individual differences can help marketers to
understand individuals’ receptivity to different kinds of communication. Specifically, personal
experience and the use of real examples may be more effective for individuals who process
information primarily in an intuitive mode, whereas logical arguments and presenting facts may
be more helpful for individuals who process information primarily in an analytical mode
(Epstein, Pacini, & Raj, 1996). For example, solving mathematic problems mainly involves
analytical-rational thinking processes, and watching movies most likely involves
intuitiveexperiential processes. Therefore, individuals differ in their responses to situations such
as ecofashion purchasing. Some consumers engage in intuitive-experiential processes and base
their responses on their feelings and affect. Others involve in analytical-rational thinking
processes and base their responses on their thoughts and cognition.
From Need for Variety to Affective Responses
The need for variety is the need that leads individuals to make a choice that differs from
the last one (Kahn, Kalwani, & Morrison, 1982; Ratner et al., 1999). In the context of fashion
products, the need for variety refers to individuals’ desire to be fashionable and to adopt new
styles in order to maintain their differentiation (Kim, Forsythe, Gu, & Moon, 2002). The
varietyseeking behavior is not caused by price reduction or based on the recommendation of a
product by someone. Rather, it is a result of the need for uniqueness (Ariely & Levav, 2000), for
change and novelty (Venkatesan, 1973), for resolving the boredom associated with daily routines
(Coombs & Avrunin, 1977), for achieving the optional stimulation level (Ehrenbur, 1982;
Faison, 1977; Venketesan, 1973; Van-Trijp, Hoyer, & Inman, 1996), and for maximizing the
utility of a product (Farquhar & Rao, 1976).
Fashion is one of the defining characteristics of a civilization (Geczy & Karaminas,
2012). Consumers are seeking variety when they purchase hedonic products such as fashion
clothing (Ratner, Kahn, & Kahneman, 1999). Seeking new and unfamiliar products is significant
for some consumers who want to adopt new styles to maintain their differentiation (Babin,
Darden, & Griffin, 1994). The issue of sustainability has become an important consideration in
the fashion industry in recent years (Pookulangara & Shephard, 2013). Consequently, more
socially and environmentally responsible practices have been increasingly implemented by the
fashion industry (Choi et al., 2011; Payne, 2014). For example, Levi’s (Weisbaum, 2013), Puma
(Pasonlini, 2013), and Gucci (Turra, 2012) have all launched eco-fashion lines. Levi’s Waste
Less Jeans are made from recycled plastic bottles and plastic waste, Puma’s InCycle product line
is made with biodegradable or recyclable items, and Gucci’s eco-friendly shoes are produced
using biodegradable plastic.
As new or even unique fashion products are introduced to consumers, eco-fashions may
be a good option to satisfy consumers’ need for variety. When consumers find eco-fashion, they
may use an intuitive-experiential process first and base their responses on their intuition,
feelings, and affect because, for consumers with a strong need for variety, “different” is strongly
associated with “good,” while “same” is coupled with “bad” (Maimaran & Wheeler, 2008).
Consumers with a strong need for variety may get more pleasure from switching than from
repeating their choices (Ratner, Kahn, & Kahneman, 1999). Therefore, consumers may have a
strong desire to adopt eco-fashion products to satisfy their feelings, affect, and need for variety.
Hence,
H1a: Consumers’ need for variety will positively influence their affective responses toward
eco-fashion products.
From Fashion Interest to Affective Responses
Consumers’ fashion interest and aesthetic needs are met by fashion clothes (Beard, 2008).
Fashion interest explains individuals’ interest in and attention to fashion products such as fashion
clothing (Chung, 2012; Gutman & Mills, 1982). Consumers who have high interest in fashion
enjoy shopping for clothing and adopt new apparel products earlier than members of other
consumer groups (Gam, 2011; Chan & Wong, 2012). These consumers are motivated by the
specific attributes of a product, such as product design, which are related to the product’s
features and performance (Sullivan, 2009). Variety in the style and design of eco-fashion creates
fashion value (Chan & Wong, 2012), and fashion consumers prefer eco-fashion that is
esthetically pleasant, which helps them feel emotional connection with it (Chan & Wong, 2012;
Ismail & Gabriella, 2012).
Fashion links individuals to their emotional needs and involves expression of their inner
personality by using different brands or status items (Batra, Ahuvia, & Bagozzi, 2012; Ismail &
Spinelli, 2012). Responses to hedonic products like fashion clothing are generally based on
affective and sensory experience of aesthetic or sensual pleasure, fantasy, fun, and excitement
(Cho, Fiore, & Russell, 2015; Dhar & Wertenbroch, 2000; Hirschman & Holbrook, 1982).
Kempf (1999) found that for hedonic products, emotional responses have stronger effect than do
cognitive responses. Batra, Ahuvia, and Bagozzi (2012) found that interest toward a fashion
product is positively associated with consumers’ affective responses such as feelings of love for
the product. Therefore, fashion products primarily involve the automatic, fast, and highly
affective experiential system of CEST. Consumers who have high fashion interest use fashion
clothing to express their “selves” to others and to differentiate themselves from others (Ismail &
Spinelli, 2012). Further more fashion clothing fulfills their personal fashion needs and makes
them feel good and happy. In other words, eco-fashion with a combination of fashion aesthetics
and ethical attributes can satisfy consumers’ fashion desire (Bratt, 1999). Thus,
H1b: Consumers’ fashion interests will positively influence their affective responses toward
eco-fashion products.
From Ecological Consciousness to Cognitive Responses
Ecological concern is a way to be respectful toward living things in the natural world
such as plants, trees, animals, and insects, while it reflects the harmony of humans and nature
(Alwitt & Berger, 1993; List, 1993). Ecologically conscious consumers show their ecological
concern and care about the nature world. Ecologically conscious consumers want to help the
environment and reduce the environmental impact of production, and they have a positive
attitude toward green clothing advertisement (Kim & Damhorst, 1998; Lin & Chang, 2012).
One obvious feature of fashion clothing is its colorful appearance. However, a high
environmental impact results from the processes of dyeing, drying, and finishing that are
necessary to keep the color fresher longer. For the production of eco-products, natural and
renewable materials are used, different production processes are employed to reduce pollution,
and the recovery of resources is attempted; the result is a lower environmental cost. As a
consequence, consumers’ concerns about environmental conservation can be addressed, and the
ecological attributes of eco-products can improve the well-being of both consumers and the
broader society (Sima, 2014). A concern for ecology in production enables ecologically
conscious consumers to maintain the integrity of their basic beliefs on helping the environment
and reducing the environmental impact of production (Epstein, 1998). This behavior enables
consumers to keep a positive self-concept by making selective purchase decision based on their
inner ethical values (Epstein, 1993, 1998) and to approach an ideal environment.
In addition to affect, cognition also is important in the processing of information in
relation to fashion (Hoyer & Stokburger-Sauer, 2012). Consumers may use the analytic-rational
system to evaluate eco-fashion products. When they engage in analytical-rational thinking, they
will elaborate their cognition to consider the ecological benefits of eco-fashion. Specifically,
consumers who have responsibilities and obligations to contribute to the natural world want to
have a comfortable feeling when wearing ethical clothing while trying to avoid unethical
companies (Similary, Jägel, Keeling, Reppel, & Gruber, 2012). Since the analytic-rational
system is slow and logic-driven (Epstein, 1990, 1991, 1993, 1994, 1998, 2003), consumers can
elaborate their cognition to evaluate the benefits such as lower ecological impact and
shortcomings such as expense of eco-fashion. The more involved consumers are with the
environment, the more likely they think about the benefits of eco-products (Alwitt & Berger,
1993). Therefore,
H2a: Consumers’ ecological consciousness will positively influence their cognitive
responses toward eco-fashion products.
From Social Consciousness to Cognitive Responses
Social consciousness is consciousness shared within a society and awareness of social
situations (Cooley, 1992). It can also be defined as social awareness, as being aware of the
problems that different societies and communities face on a day-to-day basis, and as being
conscious of the difficulties and hardships of society (Cooley, 1992). An individual is socially
concerned when she is worried about ethical issues such as low wages, excessive hours of work,
health and safety hazards, and lack of awareness of workers’ rights (Kozer & Connel, 2012) and
interested in fair trade products, regionally produced items, eco-labelled products, and recycled
materials (Jägel et al., 2012).
To reduce the price and control the cost of fashion clothing, some manufacturers may
open factories in developing countries, hire child labor, and pay low wages to them, or ignore
employees’ working environments and their human rights, all of which lead to social issues.
Ecofashion is fashion clothing designed to reduce social and environmental impacts, from the
growth of its fibers to its use and disposal (Fletcher, 2008; Niinimaki, 2010). Rational individuals
are willing to engage in conscious processing to think about ways to improve the quality of life
in society and enhance others’ lives by purchasing eco-products (Brooker, 1976).
Cognitive responses usually depend on consumers’ own personal experiences or mental
images rather than on what they see (Wright, 1980). Socially conscious consumers have societal
concerns and ecological considerations, and they may be in favor of products produced in an
ethical production system (Robert, 1995). When they engage in analytical-rational thinking, they
will elaborate their cognition to consider the social benefits of eco-fashion. Thus, socially
conscious consumers are more likely to respond to eco-fashion positively (Robert, 1995) because
eco-fashion is produced in an ethical production system that causes positive impacts on the
society. Hence,
H2b: Consumers’ social consciousness will positively influence their cognitive responses
toward eco-fashion products.
From Cognitive Responses to Affective Responses
Individuals develop both cognitive and affective evaluations in relation to a particular
environment (Proshansky, Fabian, & Kaminoff, 1983). Cognitive responses such as knowledge,
opinions, beliefs, and thoughts are produced by logic information processing in response to a
stimulus (Fishbein & Azjen, 1975), whereas affective responses are related to physiologically
experienced emotional states (Gross, 2013). This study applies the cognitive-affective response
approach because the degree of relative dominance of either a rational system or an experiential
system is determined by individual differences in preference, the situation, or the degree of
emotional involvement (Epstein, Pacini, & Denes, 1996). Consumers differ in their concerns
toward the environment, the natural world, and social issues (List, 1993). Some show a strong
sense of environmental responsibility and have many ways to satisfy their environmental beliefs
and to follow their ethical standards such as buying eco-products (Alsmadi, 2012; Cho, Thyroff,
Rapert, Part, & Lee, 2013). Further, consumers’ social and environmental concerns are positively
related to their support for socially and environmentally friendly businesses and their willingness
to pay a premium for these products (Shen, Wang, Lo, & Shum, 2012). The design of eco-
fashion focuses on its ethical attributes, which can benefit the environment and society’s
wellbeing. By emphasizing ecological and social benefits of eco-fashion and encouraging
consumers’ cognitive-affective responses, marketers can effectively promote eco-fashion
products.
As mentioned in the section on the theoretical background of cognitive-experiential
selftheory and the cognitive-affective response approach, consumers engaging in their
intuitionexperiential system may have favorable affective responses toward eco-fashion products
because eco-fashion products may satisfy their need for variety and fashion interest. If consumers
also engage their analytic-rational system, they will be aware that eco-fashion products can also
satisfy their ecological and social concerns, enhance their positive self-concept (Epstein, 1993,
1998) and reconcile their concerns in environmental and social issues.
Moreover, consumers engaging in a cognitive-affective response approach may reduce
their cognitive dissonance generated by eco-fashion purchase and lead to stronger positive
affective responses than those engaging only their intuitive-experiential system do. Cognitive
dissonance may occur when some consumers have doubts about the ecological and social
benefits of eco-fashion, view the eco-fashion as pricy, and consider eco-fashion products as not
meet their aesthetic needs (Armstrong & Kotler, 2013). Therefore,
H3: Consumers’ cognitive responses will positively influence their affective responses
toward eco-fashion products.
From Responses to Behavioral Tendencies
Humans adjust their behavior to respond to altered conditions. In this adjustment, affect
and cognition play important roles in leading to specific behavior (Koller, Floh, & Zauner, 2011).
That is, individuals’ behavior is the result of an interaction between the rational and experiential
processing systems (Epstein, 1994). Specifically, the intuitive-experiential style has an affective
basis and the analytical-rational style has a cognitive basis, which provides strong explanations
and predictions of individual behavior (Epstein, 2003). In fact, the relationship among cognition
(thinking), affect (feeling), and conation (behavior) has been discussed and demonstrated in
several consumer behavior and communication response models in marketing (Ajzen, 2001;
Kempf, 1999). Attitude adapts to the environment and is an evaluative response to stimuli, and it
is a predictor of behavioral intentions (Ajzen & Madden, 1986). Attitude comprises cognitive,
affective, and conative components and can be viewed as the result of cognition only or as the
joint effect of affect and cognition (Ajzen, 2001). For example, according to Kempf (1999),
attitude includes cognition and affect components and excludes the conation component. The
cognitive response represents an individual’s thoughts, the affective response represents an
individual’s feelings toward an object, and conative response is the intent/action component and
refers to behavior. In sum, individuals' attitudes have an effect on their behavior, and the attitude
toward behavior includes both cognitive response and affective response (Ajzen & Fishbein,
2000; Hrubes, Ajzen, & Daigle, 2001).
From Affective Responses to Purchase Intention and Willingness to Pay More
The relationship between affective responses and behavior has been demonstrated by
several researchers. For example, consumers’ affective responses can influence persuasion and
their acceptance of advertising (Batra & Ray, 1986; Peck & Wiggins, 2006). Affect is positively
related to purchase intention (Lacher & Mizerski, 1994) and willingness to pay more
(Winkielman, Berridge, & Wilbarger, 2005). Emotions resulting from perceived product design
benefits can fulfill consumers’ need for changes and contribute to their behavioral tendencies
(Franzak, Makarem, & Jae, 2014). Further, Park, Stoel, and Lennon (2008) found that affective
reaction toward apparel product has a direct effect on consumer behavioral tendencies such as
intention to purchase and willingness to pay more. Kumar, Lee, and Kim (2009) demonstrated
that both cognitive and affective responses have positive effects on Indian consumers’ purchase
intention in the apparel context.
Products attributes such as style variety and fashion design can influence consumers’
decision processes (Hoyer & et al., 2012). Moreover, perceived qualities can affect the affective
state of the consumer, which leads to a greater propensity to purchase (Farias, Aguiar, & Melo,
2013). According to Niinimaki (2010), individuals adopt fashionable clothing to satisfy their
pleasure needs, and fashion clothing can expresses individuals’ inner selves through the use of
external marks, symbols, brand names, and status items. Eco-fashion is fashion products with
innovative features such as corn fiber, recycled polyester, or vegetable tanned organic leather and
its production process may result in higher prices (Fletcher, 2008). Some consumers may select
eco-fashion even it means high prices, driven by their affective responses based on the new and
unique features of eco-fashion (Maimaran & Wheeler, 2008; Pelsmacker, Driesen, & Rayp,
2005). That is, consumers’ affective responses may influence their intention to purchase and
willingness to pay more for eco-fashion. Therefore,
H4a: Consumers’ affective responses will positively influence their purchase intention
toward eco-fashion products.
H4b: Consumers’ affective responses will positively influence their willingness to pay more
for eco-fashion products.
From Cognitive Responses to Purchase Intention and Willingness to Pay More
Cognitive responses have been viewed as critical determinants of consumer persuasion
(Brinol, Petty, & Tormala, 2004). Customers’ willingness to pay premium prices reflects the
ability of a company to differentiate its products from those of its competitors and maintain a
high price in the marketplace (Naeini, Azali, & Tamaddoni, 2015). When consumers make
purchase decisions, they are likely to make choices based on cognitive elaboration of information
(Epstein, 1993; Leventhal, 1994). Thogersen (2000) found that environmentally significant
information had a positive impact on consumer purchase behavior such as purchase intention and
willingness to pay more. Ferguson (2014) found that environmental information helped
consumers increase their awareness of the environmental and social benefits offered by
ecoproducts, which enhanced their intention to purchase eco-products. Similarly, Bower, Saadat,
and Whitten (2003) argued that purchase intention was significantly affected by label
information and that the willingness to pay more depended on the process of cognitive
elaboration toward products or service.
Chatterjee (2009) found that purchase intention and willingness to pay more were
influenced by consumers’ rational responses toward parent brands. Some consumers may
elaborate their cognition to evaluate the ecological and social benefits of eco-fashion and even
the shortcomings (e.g., higher prices) of eco-fashion. Based on these considerations reflecting
their ecological and social concerns, they adopt eco-fashion. Therefore, consumers’ cognitive
responses influence their intention to purchase and willingness to pay for eco-fashion. Taking
these considerations together,
H5a: Consumers’ cognitive responses will positively influence their purchase intention
toward eco-fashion products.
H5b: Consumers’ cognitive responses will positively influence their willingness to pay more
for eco-fashion products.
Chapter 3
Research Methods
The previous chapters have dealt with an overview of eco-fashion, the theoretical
background (Information processing mode and cognitive-experiential self-theory), assumption of
cognitive-experiential self-theory (CEST), application of information processing mode (IPO) and
cognitive-experiential self-theory (CEST), the cognitive-experiential response approach of
CEST, and the research model based on a review of the literature and addresses the research
hypotheses. Focusing on research methods to achieve the research objectives proposed in
Chapter 1, this chapter introduces both the qualitative method (focus group) and the quantitative
method (self-administered online questionnaire). Moreover, the instrument development and a
self-administered online questionnaire are described.
Objectives
1. Investigate the effects of consumers’ emotion-driven dispositions (fashion interest and
need for variety) on their affective responses toward eco-fashion.
2. Investigate the effects of consumers’ logical-driven dispositions (ecological
consciousness and social consciousness) on their cognitive responses toward eco-fashion.
3. Examine the effects of consumers’ cognitive responses on their affective responses
toward eco-fashion.
4. Examine the effects of consumers’ cognitive and affective responses on their eco-fashion
consumption behavior tendencies (purchase intention and willingness to pay more).
This chapter is divided into four sections. The first section describes instrument
development, including construct measurement of individual differences, measurement of
responses, and measurement of consumer behavioral tendencies. The second section illustrates
the focus group used to select eco-fashion clothing images as visual stimuli and to decide on the
age range of the sample. The third section explains a self-administered online questionnaire used
to collect data and test the hierarchical relationships among individual differences, responses, and
consumer behavioral tendencies based on Bettman’s consumer information processing model
(1979) and Epstein’s cognitive-experiential self-theory (1998). The fourth section discusses the
pretest conducted for the preliminary testing of the questionnaire on a small sample of
respondents by identifying and eliminating potential problems. This will ensure that the
questionnaire has proper question wording, content, sequence, and form and layout. Also, a pilot
test was used to evaluate the feasibility of the study design before using the full sample.
Instrument Development
Based upon information found in the literature review, this study adapted existing
measurement scales to identify individual differences (need for variety, fashion interest,
ecological consciousness, and social consciousness), responses (affective responses and
cognitive responses), and consumer behavior tendencies (purchase intention and willingness to
pay more). The measurement items were developed based on a literature search and were refined
based on a pretest, and validity test.
Measurements were developed in terms of individual differences (consumers’ different
processing skills in a variety of situations), responses (reactions to an event or situation), and
consumer behavior tendencies (their natural dispositions to act). All the items were 7-point Likert
scale range from ‘strongly disagree’ (1) to ‘strongly agree’ (7). Appendix III shows the original
scale items and the modified scale items used for the pretest. The final measures with refined
items for the main test are summarized in Table 17.
Measurement of Individual Differences: Need for Variety, Fashion Interest, Ecological
Consciousness, and Social Consciousness
Need for variety is defined as a person’s tendency to switch away from a choice made on
a previous occasion (Kahn, Kalwani, & Morrison, 1982; Ratner et al., 1999). Consumers
generally have a tendency to seek variation in services or goods (Simonson 1990), especially in
relation to hedonic products such as restaurant food, music, leisure activities, and fashion
products (Ratner, Kahn, & Kahneman, 1999). Consumers’ variety seeking is rooted in a need for
a change to solve the boredom associated with a brand or a product, and they seek something
different or new relative to their previous choice (Steenkamp & Baumgarner, 1995; Irani &
Hanzaee, 2011). To measure need for variety, a four-item scale was adopted from Trijp, Hoyer,
and Inman (1996); that scale is a shortened version of the consumer-specific Exploratory
Acquisition of Products (EAP) scale (Baumgarner & Steenkamp, 1996) used to measure a
consumer’s tendency to seek variation in product purchase through innovative product choices
and changing purchase experience.
Fashion interest is an indication of consumers’ attention toward fashion or their interest in
fashion clothing (Chung, 2012). Consumers have a wide range of fashion consciousness and
behavior and those who have a strong interest in fashion enjoy shopping for clothing and adopt
new apparel products earlier than do members of other consumer groups (Gam, 2011; Tigert,
Ring, & King, 1976). The nature of fashion clothing draws people into the style or fashion of the
moment, and some people place a great deal of emphasis on their clothing and keep up with
seasonal trends in clothing (O'Cass, 2001). In Arnold and Reynolds’ (2003) study, a large
number of customers report that they shop to keep up with the latest trends, to satisfy their
curiosity, or to resolve the problem of the boredom associated with another brand. For those
individuals, fashion clothing means a lot to them and they are willing to learn about new trends
and keep informed about the latest trends in fashion, styling, or innovations. To measure fashion
interest, a five-item scale was adopted from O’Cass (2000, 2001).
A concern for ecology in production causes ecologically conscious consumers to maintain
the integrity of their basic beliefs about helping the environment and reducing the environmental
impact of production (Epstein, 1998). Ecologically conscious consumers care about the nature
world, tend to help the environment, and wish to reduce the environmental impact of production
(Kim & Damhorst, 1998; Lin & Chang, 2012). Ecologically conscious consumers show their
ecological concern and pursue their environmental interests, in ways including buying eco-
products, basing their personal consumption decisions on the product’s sustainability, and
altering their behaviors in accordance with their green beliefs (Cho, Thyroff, Rapert, Part, & Lee,
2013). Consumers who have responsibilities and obligations to contribute to the natural world
want to have a comfortable feeling and try to avoid purchasing products from unethical
companies (Similary, Jägel, Keeling, Reppel, & Gruber, 2012). Therefore, they tend to purchase
less harmful products, products that cause less pollution, and recycled products and they also
switch products for ecological reasons. For ecological consciousness, a four-item scale was
adapted from Peloza, White, & Shang (2013).
Social consciousness is consciousness shared within a society and awareness of social
situations (Cooley, 1992). Socially conscious individuals believe that human beings are all
connected and they are active within their communities promoting for social, political, and
charitable causes (Hainmueller, 2012; O’Shaughnessy, 2000). Socially conscious consumers care
about ethical issues such as low wages, excessive hours of work, health and safety hazards, and
lack of awareness of workers’ rights; they are in favor of providing better living conditions for
other people, and they live up to their altruistic values of “equality” and “social justice” (Jägel et
al., 2012; Kozer & Connel, 2012). Their activities lead the way to improving the quality of life in
society, and they purchase products and services that they perceive have a positive or at least a
less negative impact on the environment and use their purchasing power to express current social
concerns (Kozar & Connell, 2013). Because of these reasons, they follow high ethical standards
and consider the ethical reputation of business when shopping (Pepper, Jackson, & Uzzell,
2009). Therefore, these consumers think about ways to improve quality of life in society by
buying eco-fashion products. For social consciousness, a three-item scale was adapted from
Wagner, Lutz, and Weitz (2009).
Measurement of Responses: Affective Responses and Cognitive Responses
Affective response means the emotional response to a situation such as the feeling of
pleasure (Cohen, Pham, & Andrade, 2008). In the eco-fashion context, the cognitive and
affective responses are reactions that result from eco-fashion. Affective responses are related to
physiologically experienced emotional states (Gross, 2013), and they can be favorable,
unfavorable, or neutral feelings (Fishbein & Azjen, 1975). The experiential attributes of
ecofashion, such as the use of innovative raw materials and unique product processes are
important to generate favorable affective responses, which may be characterized in terms such as
pleasurable, good, enjoyable, attractive, and likable. To measure affective responses, a sevenitem
scale was adapted from Moorman, Neijens and Smit (2002) and Zhou and Somn (2003).
Cognitive responses such as knowledge, opinions, beliefs, and thoughts are related to
individuals’ thinking when they listen to messages from others and when they read, watch TV,
listen to the radio, or surf the Internet (Dasgupta, 2009; Fishbein & Azjen, 1975). Cognitive
responses are usually produced by logical information processing in response to a stimulus and
depend on consumers’ own personal experiences or mental images rather than on what they see
(Wright, 1980). If individuals are very interested in the topic or the product, they will elaborate
their cognition. Eco-fashion has ethical attributes such as adherence to fair trade guidelines, the
use of low impact dyes, or being made in the USA, which can benefit the environment and
society’s well-being. When ecologically and socially conscious consumers are exposed to
ecofashion, they view eco-fashion as beneficial to the nature world, environment, and human
beings in the society. For cognitive responses, a seven-item scale was adapted from Shiv and
Fedorikhin (1988) and Wilcox, Kramer, and Sen (2011).
Measurement of Consumer Behavior Tendencies: Purchase Intention and Willingness to
Pay More
Purchase intention is a consumer’s tendency to purchase products or services,
corresponds to the consumer’s plan to buy particular goods or service sometime in the future
(Yoo & Donthu, 2001). Specifically, label information has a significant impact on consumers’
purchase intention (Bower, Saadat, & Whitten (2003). Eco-fashion made with biodegradable or
recycled materials and corn fiber and through environmentally responsible processes carries a
premium (Fletcher, 2008). These product-related attributes, along with store-related attributes,
can influence consumers’ consumption decisions (Niinimaki, 2010). For purchase intention, a
three-item scale was adapted from Rodgers (2004).
Willingness to pay more depends on the process of cognitive elaboration toward products
or service (Bower, Saadat, & Whitten, 2003). Consumers who have positive feelings toward
firms that support society’s well-being are willing to switch brands to and purchase products
from the firms (David, Kline, & Dai, 2005). Some consumers are willing to pay extra for various
types of eco-products marketed by the firms and have positive attitudes toward green
advertisements that promote eco-products (Laroche, Bergeron, & Barbaro, 2001; Mintel Oxygen
Report, 2010). For example, ethical consumers are willing to pay more when buying a product
involving ethical issues of human rights, labor conditions, animal well-being, and environment
(Pelsmacker, Driesen, & Rayp, 2005). To measure willingness to pay more, a five-item scale was
adapted from D'Souza, Gilmore, Hartmann, Ibanez, and Sullivan-Mort (2014) and Shen, Wang,
Lo, and Shum (2012).
Focus Group Interview
Focus group is the most frequently used qualitative technique and particularly useful to
explore participants’ responses, knowledge, and experiences toward unanticipated issues
(Greenbaum, 2000; Kitzinger, 1995). Discussion of the focus group has high validity and is
relatively low-cost depending on the source available (Greenbaum, 2000). Therefore, a focus
group interviews was used in this study to select appropriate eco-fashion clothing images as
visual stimuli and to decide on the age range of the study sample. To achieve the objectives of
this study, it was necessary to show eco-fashion visual images to respondents and ask questions
regarding individual differences, responses, and consumer behavioral tendencies in the
ecofashion context. In addition, the ages of respondents for this study should be decided upon.
Time, Place, Participants, and Moderator of the Focus Group
According to Greenbaum (2000) and Kitzinger (1995), the focus group should be
conducted in an informal and natural way where participants are free to discuss and a relaxed,
informal atmosphere is necessary, Participants in a focus group should be recruited on the basis
of similar demographics, psychographics, buying attitudes, or behavior. A trained moderator is
needed for a successful focus group.
The focus group was conducted in January 2015 by an experienced moderator who is a
professor of Retail, Hospitality, and Tourism Management Department at the University of
Tennessee, and nine participants who were undergraduate students in the Department of Retail,
Hospitality, and Tourism Management at the University of Tennessee were involved in the
discussion. The participation was voluntary and had no extra credit or incentive reward. The
moderator led the discussion in one classroom and maintained the relaxed and informal
environment.
Visual Image Selection and Age Determination
A number of organizations work with fashion designers, organizations and businesses to
facilitate, support, or monitor sustainable practices and standards, and together they develop
standards and attributes for eco-fashion. In this study, only eco-fashion images with authorized
symbols such as fair trade certified cotton, certified organic cotton, made in USA, or low impact
dyes were considered as stimuli.
A number of images that contained male and female eco-fashion with different designs
and styles including shirts, T-shirts, sweaters, fleece clothing, jackets, and jeans were identified
from different websites based on key words such as eco, green, ethical, natural, organic, and
sustainable typed into the search engine (Google). Then, professionals including one professor
and four PhD students in the Department of Retail, Hospitality, and Tourism Management at
University of the Tennessee finalized forty-six male and forty-six female eco-fashion images
from high-end outdoor clothing companies such as Patagonia, fair trade fashion pioneers such as
People Tree, organic and sustainable designer apparel companies such as Loomstate, and
USmade eco-friendly clothing companies such as Soul Flower.
Male and female eco-fashion images with different designs and styles, such as shirt,
Tshirt, sweater, fleece, jacket, and jeans, were shown to nine participants who are undergraduate
students in Department of Retail, Hospitality, and Tourism Management at University of
Tennessee. Specifically, forty-six female eco-fashion images were grouped into fourteen sets of
images based on styles and color, and forty-six male eco-fashion images were grouped into
fifteen sets of images based on styles and color. After viewing images, nine participants
discussed their ideas, thoughts, and feeling toward eco-fashion images based on styles, design,
age range, and gender preference of eco-fashion images.
The focus group discussion questions were open-ended and were worded in such a way
that participants provide free-flowing responses to the given topic. Open-ended questions are
opposite to closed-ended questions that can be answered with a simple “yes” or “no.”
Exploration questions, such as which images could better represent female or male eco-fashion,
what do you think/feel about those eco-fashion images, and which age ranges would fit those
female/male eco-fashions were asked. The questions for the focus group are shown in Appendix
I. Based on the discussion guided by the moderator, the number of eco-fashion images was
reduced to eight female and eight male images. Then, eight female and eight male eco-fashion
images were selected as visual stimuli. The age ranges of the sample were decided as 18-55 by
the focus group.
Other Considerations for the Focus Group
Because all nine participants were female, participants were also required to construct
responses from the points of view of their family members (brothers, dads, and grandpas) or their
boyfriends. In addition, a sample questionnaire with eighteen questions was used to ask about
participants’ feelings and thoughts of eco-fashion images and to confirm their selection for the
final sixteen eco-fashion visual images (eight female and eight male visual images). Questions
were asked to rate items of “eco-fashion is comfortable,” “eco-fashion is beneficial,” and
“ecofashion is a wise choice” to confirm the participants’ selection of the final sixteen visual
images. One question “eco-fashion is refined” was deleted because of the ambiguity of the
question. The questions used are shown in Appendix II. The mean score of the sixteen questions
was 5.66, implying that the selection of eight eco-fashion images was satisfactory.
Self-Administered Online Questionnaire
To achieve this study’s objectives, it was necessary to show eco-fashion visual images to
respondents and ask them questions regarding individual differences, responses, and consumer
behavioral tendencies in the eco-fashion context. The self-administered online questionnaires are
less expensive and anonymous and can be distributed in large numbers at once and involve less
administrative time (Hair, Celsi, Money, Samouel, &d Page, 2011). Respondents could read and
answer questions in a variety of locations by using computers or other electronic devices by
themselves, a condition which generates less interviewer bias (Hair, Celsi, Money, Samouel, &d
Page, 2011). Therefore, a self-administered online questionnaire was selected to obtain
information from respondents.
The objective of the self-administered online questionnaire was to test the questionnaire,
to evaluate the feasibility of the study design before the test was administered to the full sample,
and to test the research model in this study. Specifically, a pretest was conducted to test the
questionnaire and to ensure that the questionnaire has proper question wording, content,
sequence, and form and layout, a pilot test was used to evaluate the feasibility of the study design
before using the full sample, and the main test was used to test the proposed hypotheses.
Questions regarding fashion interest, need for variety, ecological and social consciousness,
cognitive and affective responses toward eco-fashion, willingness to pay more toward
ecofashion, and purchase intention toward eco-fashion were included in the survey. In sum, the
selfadministered online questionnaire was used for a pretest, a pilot test, and the main test.
Sample Size
Sample size plays an important role in the accuracy of results (Burns & Bush, 2006) and
in determining the appropriateness of the chosen statistical technique (Hair, Black, Babin, &
Anderson, 2006). This study employed confirmatory factor analysis (CFA) and structural
equation modeling (SEM). A wide range of recommendations regarding sample size in factor
analysis have been suggested for running CFA and SEM. Breckler (1990) surveyed 72 studies in
which SEM was conducted and found the median sample size to be 198. However, MacCallum,
Widaman, Zhang, and Hong (1999) recommended the minimum desirable number of 250 for a
CFA analysis. A sample size of 300 for CFA analysis is good, while a sample size of 500 for
factor analysis is favored. In SEM, sample sizes less than 100 are usually considered to be small
and the sample size should not be small because SEM relies on mode-fitting criteria that are
sensitive to sample size. ((Burns & Bush, 2006; Kline, 2005). Garver and Mentzer (1999) and
Hoelter (1983) suggested a critical-sample size of 200 to provide sufficient statistical power for
data analysis. Based on the above considerations, this study obtained a total sample size of 253
for the pretest, 150 for the pilot test, and 657 for the main test.
The Design of Self-Administered Online Questionnaire
According to Hair et al. (2011), questions should be grouped by topic and should start
with general questions leading to specific ones, while demographic and socioeconomic questions
should be asked at the end of the survey. Therefore, the survey was divided into four parts in
terms of its form and layout. The first part is the introduction including the purpose of the study,
the perceived benefits of the survey, the time required to take the survey, the research
participants’ rights, the potential risks to the research participants, and the assurance of
confidentiality for participants of the survey. With the first part asking a screening question to
include only participants whose ages are 18 – 55, the second part contains general questions
about fashion interest, need for variety, and ecological and social consciousness. The third part is
comprised of eight female and eight male eco-fashion images that were designed to present male
participants with male eco-fashion images and female participants with female eco-fashion
images. Finally, the last part includes specific questions about issues such as cognitive and
affective responses toward eco-fashion, willingness to pay more for eco-fashion, and purchase
intention toward eco-fashion, along with demographic questions.
The questionnaire was designed using a survey tool website (Quadrics), and the online
survey link was sent to each respondent. The questionnaire was designed to be completed in less
than 15 minutes. A screening question was asked at the beginning of the survey to include only
respondents whose ages were 18 – 55, and then the general and specific questions and
demographic questions followed. All questions were close-ended and included nominal such as
gender and ethnicity, ordinal such as income, and ratio types such as such as those regarding age.
For each question, the forced response function in Qualtrics was used, which means that
participants could not skip to the next question without finishing the current one.
After approval from the Institutional Review Board (IRB), a pretest was conducted for the
preliminary testing of the questionnaire, a pilot test was used to evaluate the feasibility of the
study design before using the full sample, and the main test was used to test the proposed
hypotheses.
Pretest
A pretest can be used to test the questionnaire on a small sample of respondents to
identify and eliminate potential problems (Malhotra, 2010). To ensure that the questionnaire has
proper question wording, content, sequence, and form and layout, a pretest was conducted and
surveys were distributed to undergraduate students in two classes in the Retail, Hospitality, and
Tourism Department at a public university in Tennessee in Spring 2015. A total of 260 surveys
were collected in the course of two weeks during the academic session, and extra credits were
given to the students who completed the survey. As a result, 253 surveys were determined to be
valid. The self-administered online questionnaire of the pretest is shown in Appendix III.
Descriptive Statistics of the Pretest
The descriptive statistics of the pre-test sample are shown in Table 1 and contain
demographic information on respondents such as gender, age, and ethnicity. Analysis of
respondents’ demographic information shows that the respondents represented more females
(70.00%) than males. About three-quarters were Caucasians (74.70%) in the age groups of 18–25
(71.9%) years. The mean age of respondents was 25.83. Because respondents were
undergraduate students and the total household income question may represent a mix of family
and personal incomes (a single person, the married couple, or respondents’ parents), the
information on income is not reported here. Means for scale items range from 2.901 to 5.54, and
standard deviations range from 1.19 to 1.839.
Evaluating and Testing the Questionnaire
Two experts in Retail, Hospitality, and Tourism Management at University of Tennessee
reviewed all scale items and evaluated the question wording, content, sequence, and form and

layout. Among forty-eight pretest scale items, two scale items of need for variety are negatively
worded and other items are positively worded. To check whether the measurement items of need
for variety including two negative statements with reversed coding and two positive statements
are reliable, the researcher decided to check internal consistency (Cronbach’s Alpha) of need for
variety.
Cronbach’s Alpha is the most commonly used measure of internal consistency reliability,
and its cutoff criterion is 0.6 (Hair, 2010). The alpha of an adequate scale should be at least .70,
and the alpha of a good scale should be .80 or higher. Reliability assessed by Cronbach's alpha is
based on the indicators’ inter-correlations, and the higher indicators’ inter-correlations are, the
higher the alpha is (Miller, 1995). In this study, Cronbach’s alpha was used to determine the
reliability of each construct.
The measurement items of need for variety were two items with reversed statements and
two items with positive statements. After turning the reversed statements to positive statements,
the researcher checked the reliability of need for variety with four items. The reliability of need
for variety with four items was 0.393 that is much lower than the cut-off level of 0.60. Further,
the reliability of two negative statements after reversed coding was 0.824 and that of two positive
statements was .757. Therefore, the measurement items of need for variety need further
improvement.
It was concluded that two items with reversed statements (“I would rather stick with a
product I usually buy than try something I am not very sure of” and “If I like a product, I rarely
switch from it just to try something different”) may have provided some confusion to the
respondents. In other words, respondents may be confused about the mix of two reverse-ordered
statements and two positive statements. This may have been the cause of low reliability of the
need for variety construct.
To obtain a reliable measure of need for variety, at least three scale items had to be used
for the measuring of one construct (Hair, 2010; Kenny, 2014). So, the researcher decided to
delete the two items with reversed statements and add more items. Five items in the exploratory
change seeker scale (Steenkame & Baumgartner, 1995; Campbell & Goodstein, 2001;
VazquezCarrasco & Foxall, 2006) were added to the need for variety construct. The refined
measurement items of need for variety are shown in Table 2.

NFV7 7. I like to continue doing the same old things rather than try new and different things. ®
NFV8 8. I prefer a routine way of life to an unpredictable one full of change. ®
Pilot Test
Pilot test is a small-scale trial and is used to evaluate the feasibility of the study design
before using the full sample. Pilot test data were collected from 150 participants within one week
in June 2015 by a marketing research firm in California, and participants were online consumer
panels of the marketing research firm. Once participants agreed to do the study, they received the
survey link. After participants completed a full survey, they received an incentive of $2.5. There
was no incomplete survey, and all surveys were usable.
Descriptive Statistics of the Pilot Test
The descriptive statistics of the pilot test are shown in Table 3 and contain the
demographic information on respondents such as gender, age, and ethnicity. Analysis of
respondents’ demographic information shows that the respondents are comprised of more
females (71.30%) than males. The Majority of the respondents are Caucasians (79.30%), and
about half of them are in the age groups of 46–55 years (48.00%). The mean age of respondents
is 44.2. Majority respondents have income lower than $80,000–$99,999 (60.7%).
Evaluating and Testing the Questionnaire
Wording, content, sequence, and form and layout of all questions have been verified by
undergraduate students in the pretest. However, to ensure the study can work in the “real world”
and to identify potential practical problems by using people who are similar to target population
(Teijlingen & Hundley, 2001), a pilot test with 150 online consumer panels was conducted. By
analyzing participants’ responses, the researcher found that respondents were still confused for
measurement items of need for variety, probably because of the reversed statements.
The refined measurement items of need for variety still included two items with reversed
statements (NFV 7 and NFV 8), the researcher decided to compute the inter-item correlation of
the measurement items. The inter-item correlation of need for variety is shown in Table 4. After
turning the reversed statements (NFV 7 and NFV 8) to positive statements (NFV 7N and NFV
8N), the researcher checked the inter-item correlation of need for variety. Inter-item correlation
examines how well one item is related to all other items in a scale (Hair, 2010). The inter-item
correlations of eight items are shown in following Table 4. The low inter-item correlations of
need for variety ranged from .058 to .203, which were caused by two reversed statements. In
other words, two items with reversed statements (NFV 7 and NFV 8) had extremely low

measurement items of need for variety. The final measure for need for variety is shown in Table
5.
Then, internal consistency (Cronbach’s Alpha) was checked for all constructs to ensure
that the final measures with refined items for the main test is reliable. Specifically, Cronbach’s
alpha was used to determine how well the measurement items measure the same construct. The
reliabilities of all constructs are shown in Table 6 and range from 0.870 to 0.986. Cronbach’s
alpha of each construct is above the cut-off level of 0.70 (Hair 2010), thereby indicating the
internal consistency.
The final measures used to evaluate the feasibility of the study design before using the
full sample are shown in Table 7 and were tested by the online consumer panels. One item (I
would pay a premium for certified sustainable clothing) of willingness to pay more was deleted
because this item strongly correlated with WTPM1 (r = 0. 900), WTPM2 (r = 0.780), WTPM (r
= 0.716), and WTPM4 (r = 0.908).
Main Test: Overview of the Sample
Main test was used to test the proposed hypotheses. Main test were collected from 657
participants within one week in June 2015 by a marketing research firm in California, and
participants were online consumer panels of the marketing research firm. Participants received an
incentive of $2.5 after they completed a full survey. There was no incomplete survey, and all
surveys were usable.
Descriptive Statistics of the Main Test Sample
The descriptive statistics on the measurement items are shown in Table 8. The
demographic information on respondents such as gender, age, and ethnicity is recorded. Analysis
of respondents’ demographic information shows that respondents are comprised of more females

(70.00%) than males. About three-quarters of the respondents are Caucasians (74.70%), and
about one-third of them are in the age groups of 36–45 (33.79%) years or 46–55 (36.99%). The
mean age of respondents is 41.02.
Assessment of Normality for the Main Test
The assessment of normality for the measurement items used in the main test is shown in
Table 9, which contains descriptive statistics of each measurement item such as minimum,
maximum, mean, standard deviation, skewness, and kurtosis. The mean values range from 3.61
to 5.74, and the standard deviations range from 1.167 to 2.012 on the 7-point scale. To check the
univariate normality of data, values for skewness and kurtosis have been calculated. For a normal
distribution, the values of skewness should be near 0, and values of kurtosis between –2 and +2
are considered acceptable (George & Mallery, 2010). In this study, the absolute values of
skewness range from 0.003 to 1.049 and the absolute values of kurtosis range from 0.027 to
1.293, indicating that the main test data are normally distributed.

Chapter 4
Data Analyses and Results
The previous chapters have dealt with instrument development, the qualitative method
(focus group) and the quantitative method (self-administered online questionnaire) that are used
to achieve the research objectives. This chapter discusses data analyses of the main test,
introducing a confirmatory factor analysis (CFA) performed to evaluate the measurement model
and a SEM used to test hypotheses. As the first step in data analyses, an overview of the main
test sample including descriptive statistics and an assessment of the normality of the main test
sample is performed. The two-step approach (Anderson & Gerbing, 1988) is used to validate the
measurement model and to test the proposed hypotheses. As the first step, a confirmatory factor
analysis (CFA) is conducted to evaluate whether all measures are reliable and valid. As the
second step, a SEM is used to examine the causal relationships among all latent variables
(fashion interest, need for variety, ecological consciousness, social consciousness, cognitive
responses, affective responses, purchase intention, and willingness to pay more). Both the
measurement model and the structural model are assessed using AMOS 20 with the maximum
likelihood method. The model fits of the estimated models are assessed by chi-square (χ2) tests,
the ratio of chi-square to degrees of freedom, the comparative fit index (CFI), the Tucker-Lewis
index (TLI), and the root mean square error of approximation (RMSEA).
Confirmatory Factor Analysis
A confirmatory factor analysis (CFA) is used to evaluate all measures and to test how
well the measured variables represent the number of constructs (Malhotra, 2010). A CFA is
conducted for each construct (need for variety, fashion interest, ecological consciousness, social
consciousness, affective responses, cognitive responses, purchase intention, and willingness to
pay more) and the measurement model.
The model fits of each construct and the estimated models are assessed by chi-square (χ2)
tests, the ratio of chi-square to degrees of freedom, the comparative fit index (CFI), the
TuckerLewis index (TLI), and the root mean square error of approximation (RMSEA). Because
chisquare is sensitive to the sample size, relative chi-square (chi-square/degree of freedom) has
been used to evaluate model fit. Values of the ratio between 2 and 5 indicate acceptable fit level
and values less than 2 indicate good fit (Kenny, 2012). For the RMSEA, values less than .05
indicate good fit; values between .05 and .08 show reasonable fit; values between .08 and .10
reflect mediocre fit; and values > .10 indicate poor fit to the data (MacCallum, Browne, &
Sugawara, 1996). For the CFI, values of .90 or greater have been found to indicate good model
fit (Schumacker & Lomax, 2004). The Tucker-Lewis Index (TLI) is also called the non-normed
fit index (NNFI). A value of 0.90 or greater for this index has been found to indicate good model
fit (Kenny, 2012).
CFA for Each Construct
Before developing a measurement model, the measurement items for each construct are
subjected to confirmatory factor analysis (CFA) by using AMOS 20 to identify whether the
measurement variables reliably reflected the latent variables (need for variety, fashion interest,
ecological consciousness, social consciousness, affective responses, cognitive responses,
purchase intention, and willingness to pay more). Fit statistics such as number of items used for
each construct, the chi-square (χ2), the ratio of chi-square to degrees of freedom (χ/df), the
comparative fit index (CFI), the goodness-of-fit index (GFI), and the root mean square error of
approximation (RMSEA) are reported in Table 10. According to the fit statistics for each
construct, the ratio of chi-square to degrees of freedom (χ/df) for all constructs are greater than 5
and the RMSEA for all constructs are greater than 0.1, which indicate the poor fit. Therefore, the
models need to be improved.

RMSEA: < 0.05 very good, < 0.08 acceptable, < 0.10 mediocre, ≥ 0.10 poor errors of approximation (Byrne, 2001).
Model Improvement
If a model poorly fits to the data, three statistical criteria can be used to evaluate the
models: standardized regression weights, standardized residual covariance, and modification
indices (MIs) that are a univariate index used to estimate the amount of an unestimated
relationship and to improve the overall fit of the model. A standardized regression weight less
than 0.4 is unacceptable because of measurement error (Singh, 1995). An absolute value of
standardized residual covariance greater than 2.58 indicates a substantial prediction error
(Joreskog & Sorbom, 1988). An excessively high MI is an indication of misfit. A MI is
expressed as chi-square statistics with one degree of freedom and the value of MI greater than ten
was considered high (Bryne, 2013; Joreskog & Sorbom, 1988; Hari et al., 1998). Based on these
criteria, model modifications will be made by eliminating the measurement items with a
standardized regression weight less than 0.4, standardized residual covariance greater than 2.58,
and high modification indices.
Need for variety
Six items were used to measure need for variety (NFV), and standardized regression
weights range from 0.69 to 0.90, indicating a good fit of the model. The absolute values of
standardized residual covariance are less than 2.58, showing a good fit of the model. The error
variance between NFV1 and NFV4 showed a very high modification index value of 54.754,
however the standardized regression weight of NFV1 (0.72) and NFV4 (0.88) are much higher
than 0.4 and the standardized residual covariance (1.95) is lower than 2.58. Then, the researcher
decided to correlate the error of NFV1 and NFV4, which is another way use to improve the fit
(Joreskog & Long, 1993; Gerbing & Anderson, 1984). The CFA of need for variety was run
again. The CFA was run again on the model and the improved model fit is indicated in Table 11.

Fashion interest
Five items were used to measure fashion interest (FI), and all items have significant
standardized regression weights ranging from 0.95 to 0.98, indicating a good fit of the model.
The absolute values of standardized residual covariance are less than 2.58, showing a good fit of
the model. Four pairs of error variance showed high modification indices: FI6e and FI7e
(MI=26.910), FI5e and FI7e (MI=26.025), FI4e and FI6e (MI=23.268), and FI4e and FI5e
(MI=24.765). Items FI5 and FI6 were frequently available across four pairs of error variance
with high modification indices and the researcher decided to remove those two items. The CFA
was run again on the model and the improved model fit is indicated in Table 11.
Ecological consciousness
Four items were used to measure ecological consciousness (EC). All items have
significant standardized regression weights ranging from .82 to .91, which indicates a good fit of
the model. The absolute values of standardized residual covariance are less than 2.58, indicating
a good fit of the model. Hence, no change has been made to the measure of ecological
consciousness.
Social consciousness
Three items were used to measure social consciousness (SC). All items have significant
standardized regression weights ranging from .76 to .86, showing a good fit of the model. The
absolute values of standardized residual covariance are less than 2.58, indicating a good fit of the
model. Hence, no change has been made to the measure of ecological consciousness.
Affective responses
Seven items were used to measure affective responses (AR). All items have significant
standardized regression weights ranging from .89 to .92, and the absolute values of standardized
residual covariance are less than 2.58, exhibiting a good fit of the model. However, the error
variances between AR5 and AR7, between AR6 and AR7, and between AR5 and AR6 showed
extremely high modification index values of 188.70, 68.03, and 43.24 respectively. Therefore,
AR5, AR6, and AR7 were removed. The improved model fit after the running is shown in Table
11.
Cognitive responses
Seven items were used to measure cognitive responses (CR). All items have significant
standardized regression weights ranging from .80 to .94, and the absolute values of standardized
residual covariance are less than 2.58, reflecting a good fit of the model. The error variance
between CR7 and CR6 showed a high modification index value of 34.97. The error variance
between CR7 and CR1 showed a high value of 19.59. The error variance between CR7 and CR4
showed a high value of 16.75. Thus, CR7 was removed. CFA was run again on the model, and
results of the improved model fit appear in Table 11.
Willingness to pay more
Four items were used to measure willingness to pay more (WTPM). All items have
significant standardized regression weights ranging from .68 to .96, showing a good fit of the
model. The absolute values of standardized residual covariance are less than 2.58, indicating a
good fit of the model. Hence, no change has been made to the measure of willingness to pay
more.
Purchase intention
Three items were used to measure purchase intention (PI). All items have significant
standardized regression weights ranging from .91 to .96, and the absolute values of standardized
residual covariance are less than 2.58, revealing a good fit of the model. Therefore, no change
has been made to the measure of purchase intention.
CFA for the Measurement Model
A confirmatory factor analysis (CFA) is used to validate the measurement model
(Malhotra, 2010). In this study, CFA was conducted for the measurement model that included eight
constructs to test how well the measured variables represent the number of constructs. The model
fits of the measurement model is assessed by chi-square (χ2) tests, the ratio of chi-square to
degrees of freedom, the comparative fit index (CFI), the Tucker-Lewis index (TLI), and the root
mean square error of approximation (RMSEA).
For the measurement model, a correlation matrix of the variables was first analyzed to
indicate relationships among eight constructs and to identify the presence of highly correlated
constructs. As shown in Table 12, the following pairs of variables are highly correlated: affective
responses with cognitive responses (r = 0.930), purchase intention with willingness to pay more
(r = 0.827), and ecological consciousness with social consciousness (r = 0.814), indicating the
possible issues of multicollinearity. Therefore, correlations among all measurement items of
ecological consciousness and social consciousness and correlations among all measurement
items of purchase intention and willingness to pay more were conducted.
As shown in Table 13, correlations among all measurement items of purchase intention
and willingness to pay more are moderate or high and range from 0.588 to 0.898, which caused
the researcher to consider whether purchase intention and willingness to pay more represent the
same variable and should be combined as one construct. However, purchase intention and
willingness to pay more have been used as completely different constructs according to the
literature. Purchase intention refers to the consumer tendency to purchase products or services

and the resistance to switch to other products or services (Yoo & Donthu, 2001), while
willingness to pay more takes into account the price factor and refers to the maximum price that
a given consumer is willing to pay for a product or service (Bower, Saadat, & Whitten, 2003).
Thus, the researcher decided to test whether purchase intention and willingness to pay more
represent the same construct or need to be used as different constructs by using a chi-square
difference test.

For purchase intention and willingness to pay more, the researcher compared two models,
an unconstrained measurement model and a constrained measurement model (PI2WTPM). In the
constrained measurement model, the research assigned purchase intention and willingness to pay
more as one construct by assigning the correlation between purchase intention and willingness to
pay more as one. If the unconstrained measurement model and the constrained measurement
models are the same, purchase intention and willingness to pay more represent the same
construct. In contrast, if those two models are statistically different, purchase intention and
willingness to pay more are different constructs. As indicated in Tables 14 and 15, the
constrained measurement model (PI2WTPM) is statistically and practically different from the
unconstrained model.

Table 16 reveals the correlations among all measurement items of ecological
consciousness and social consciousness. As shown in Table 16, the following pairs of items are
moderately correlated: EC3 with SC1 (r = 0.628) and EC3 with SC1 (r = 0.625). Ecological
consciousness and social consciousness are different constructs according to the literature. Social
consciousness is consciousness shared within a society and indicates awareness of social
situations (Cooley, 1992). On the other hand, consumers who are ecologically conscious want to
help the environment and reduce their products’ environmental impact (Lin & Chang, 2012).
Therefore, the researcher determined it was necessary to test whether ecological consciousness
and social consciousness are the same or different constructs by using a chi-square difference
test.

For ecological consciousness and social consciousness, the researcher treated ecological
consciousness and social consciousness as the same construct by assigning the correlation
between ecological consciousness and social consciousness as one and then compared the
unconstrained measurement model with the constrained measurement mode (EC2SC). As shown
in Tables 17 and 18, model EC2SC is statistically and practically different from the
unconstrained model. That is, ecological consciousness and social consciousness are different
constructs, and then the researcher linked the error variance between them to solve the high
correlation problem.

CFA was conducted for the measurement model and the fit statistics of the initial
measurement model are shown in Table 19, which includes eight constructs. All eight latent
variables were allowed to inter-correlate freely without attribution of a causal order. The
covariance matrix of the measurement model is positive definite, indicating that multicollinearity
is not a concern in evaluating the model. As an indicator of good model fit to the data, Kline’s
(1998) criteria are used (i.e., CFI ≥ .90, GFI ≥ .90, RMSEA ≤ .08). The fit statistics of the initial
measurement model are: χ2 (467) = 2098.304; χ2 /df = 4.493; CFI = .935; TLI = .926; and
RMSEA = .073 (See Table 19). The ratio of chi-square to degrees of freedom indicates the
acceptable fit level, which means the model can be further improved.
Model Improvement
Standardized regression weights, standardized residual covariance, and modification
indices (MIs) can be used to improve measurement model. To improve the model fit,
measurement items with significant standardized regression weights less than 0.4, standardized

residual covariance greater than 2.58, and having high modification indices will be deleted
(Bryne, 2013; Joreskog & Sorbom, 1988; Singh, 1995).
Three pairs of error variance showed high modification indices: EC1 and EC3 (92.328),
and CR2 and CR5 (38.890). Then, the researcher decided to correlate the error of EC1 and EC3,
and CR2 and CR5. The CFA was run again on the model and the improved model fit is indicated
in Table 19. Reliability
In this study, composite reliability was used to report reliability of measurement model.
The final measurement model comprises 8 constructs measured by 33 items. Factor loadings of
all items range from 0.692 to 0.965, and all paths are significant (p < 0.001). The composite
reliability of each construct ranges from 0.87083 to 0.966, meeting the minimum criterion of
0.70 (Nunnally & Bernstein, 1994). The model fits the data very well and all measures are
reliable. Factor loadings and composite reliabilities of the final measurement model are provided
in Table 20.

Validity
Once reliability has been established, convergent and discriminant validity should be
assessed; and convergent validity is supported by the factor loadings, the composite reliability,
and average variance extracted values (Hair et al, 2010). In this study, factor loadings of all items
range from 0.692 to 0.965, and all paths are significant (p < 0.001). The composite reliability for
each construct exceeds the recommended level of .70. The AVE values, ranging from 0.604 to
0.903, are greater than the recommended threshold value of .50. Therefore, all measures are
convergent.
The discriminant validity can be tested by examining whether the values of average
variances extracted (AVE) exceed the squared correlation coefficients (i.e., shared variance)
between all possible pairs of constructs (Fornell & Larcker, 1981). Table 21 indicates that values
in the diagonal entry (square-root of AVE) are greater than values in the particular row and
column (square correlation between constructs), confirming discriminant validity. Hence, the
model fits the data very well and all the measures employed in this study are valid.

Diagonal entries show the square-root of average variance extracted by the construct. Off-diagonal entries
represent the variance shared (squared correlation) between constructs.
The measurement model fits the data very well and all measures are reliable and valid.
The fit statistics of the final measurement model are: χ2 (464) = 1661.995; χ2 /df = 3.581; CFI =
0.952; TLI = 0.946; and RMSEA = .063 (See Table 22). Structural Model
A structural model was used to examine the causal relationships among fashion interest,
need for variety, ecological consciousness, social consciousness, cognitive responses, affective
responses, purchase intention, and willingness to pay more. The structural model was assessed by
using AMOS 20 with the maximum likelihood method. The model fits of the estimated models
are assessed by chi-square (χ2) tests, the ratio of chi-square to degrees of freedom, the
comparative fit index (CFI), the Tucker-Lewis index (TLI), and the root mean square error of
approximation (RMSEA).
Hypotheses Testing
The hypothesized relationships among variables were tested in the structural model. The
structural model fits the data very well and all hypotheses are supported except H1b. The fit
indices of the structural model are: χ2 (479) = 1964.016, χ2/df = 4.100, CFI = 0.941, TLI =
0.935, and RMSEA = 0.069. Table 22 presents the results of the hypothesis testing including the
standardized regression weights, standard errors, and critical ratios.
H1: Emotion-Driven Disposition -> Responses
The path between need for variety and affective responses toward eco-fashion clothing (β
= 0.058, p = 0.029) is significant. However, the path between fashion interest and affective
responses toward eco-fashion clothing is not significant (β = 0.0151, p = 0.546). Hence, H1a is
supported, while H1b is not.

(β = 0.485, p < 0.001) and between affective responses and willingness to pay more toward

supported.

Discussion of Findings and Implications
The research model developed for this study aimed to provide suggestions on how to
effectively promote eco-fashion. Employing the simple information processing model (Bettman,
1979) and cognitive-experiential self-theory (Epstein, 1998), the model in this study explains the
relationships among the individual differences (need for variety, fashion interest, ecological
consciousness, and social consciousness), responses (affective and cognitive responses toward
eco-fashion), and consumer behavior tendencies (purchase intention and willingness to pay
more). The findings indicate that consumers’ emotion-driven dispositions (need for variety) and
logic-driven dispositions (ecological consciousness and social consciousness) positively
influence their responses (affective and cognitive responses toward eco-fashion) and eventually
their behavior tendencies (purchase intention and willingness to pay more) toward eco-fashion.
In addition, cognitive responses have a strong effect on affective responses, and humans’
analytical-rational system is more important than their intuitive-experiential system in the
ecofashion context. This chapter discusses the theoretical and implications and ends with a
discussion of the study’s limitations and future research directions.
Discussion of Findings
Research Model
The specific research objectives of this study were to (1) investigate the effects of
consumers’ emotion-driven dispositions (fashion interest and need for variety) on their affective
responses toward eco-fashion; (2) investigate the effects of consumers’ logic-driven dispositions
(ecological consciousness and social consciousness) on their cognitive responses toward
ecofashion; (3) explore the effects of consumers’ cognitive responses on their affective responses
toward eco-fashion; and (4) explore the effects of consumers’ cognitive and affective responses
on eco-fashion consumption behavior tendencies (purchase intention and willingness to pay
more).
Figure 6. Structure Equation Model of Eco-Fashion Consumption
The Effect of Emotion-Driven Dispositions on Affective Responses
The results shown in Figure 6 indicate that need for variety positively influences
consumers’ affective responses. Interestingly, consumers’ need for variety is an important
predictor of their affective responses toward eco-fashion; however, the results do not support the
existence of a relationship between consumers’ fashion interest and affective responses. Limited
variety in styles and fewer choices with regard to eco-fashion could explain why consumers’
fashion interest had no significant impact on their affective responses.
The findings support the conclusion that consumers having a strong need for variety get
more pleasure from switching to a new product than from repeating their choices, viewing
“different” as “good” and considering “the same” as “bad” (Maimaran & Wheeler, 2008; Ratner,
Kahn, & Kahneman, 1999). The variety-seeking behavior is a result of the need for uniqueness,
for change and novelty, for resolving the boredom associated with daily routines, for achieving
the optional stimulation level, and for maximizing the utility of a product (Ariely & Levav, 2000;
Coombs & Avrunin, 1977; Ehrenbur, 1982; Farquhar & Rao, 1976; Faison, 1977; Van-Trijp,
Hoyer, & Inman, 1996; Venkatesan, 1973). Therefore, consumers may buy eco-fashion products
to satisfy the desire for a change, and need for variety.
The Effect of Logic-Driven Dispositions on Cognitive Responses
The results shown in Figure 6 indicate that ecological consciousness and social
consciousness positively influence cognitive responses. Further, ecological consciousness has a
stronger impact on cognitive responses than social consciousness does, which indicates that
consumers’ ecological consciousness is a particularly important predictor of their cognitive
responses. The finding that ecological consciousness positively influences cognitive responses
supports the notion that a concern for ecology in production enables ecologically conscious
consumers to maintain the integrity of their basic beliefs about helping the environment and
reducing the environmental impact of production (Epstein, 1998).
The findings also support the conclusion that socially conscious consumers are more
likely to respond to products produced in an ethical production system that causes positive
impacts on the society (Robert, 1995). The result is also consistent with the findings that socially
conscious consumers are more likely to respond to eco-fashion positively and elaborate their
cognition as they consider the social benefits of eco-fashion (Robert, 1995). As such, logicdriven
individuals such as ecologically conscious and socially conscious individuals are willing to
engage in conscious processing when they buy eco-products. The cognitive responses toward
eco-products certainly translate into improving the quality of life in society and enhancing
others’ lives.
The Effects of Cognitive Responses on Affective Responses
Interestingly, consumers’ cognitive responses toward eco-fashion have a very strong
effect on their affective responses. Further, consumers’ logic-driven dispositions (ecological
consciousness and social consciousness) have stronger effects on their cognitive responses and
eventually their behavior outcome (purchase intention and willingness to pay more) than the
effect that their emotional-driven dispositions have on their affective responses and behavior
outcome (purchase intention and willingness to pay more). The results imply that humans’
analytical-rational system is more important than the intuitive-experiential system. Moreover,
only emphasizing affective responses to eco-fashion is not enough because emotion-driven
behaviors are typically short in duration (Cohen, Pham, & Andrade, 2008), and individuals
cannot have an emotional reaction to a stimulus without some sort of cognitive appraisal (Yap &
Tong, 2009). In other words, the cognitive-affective response approach is strongly supported.
The finding supports the conclusion individuals develop both cognitive and affective
evaluations in relation to a particular environment (Proshansky, Fabian, & Kaminoff, 1983).
Cognitive responses are produced by logical information processing in response to a stimulus
(Fishbein & Azjen, 1975), whereas affective responses are related to psychologicallyexperienced
emotional states (Gross, 2013). Moreover, when consumers engage in a cognitiveaffective
response approach, their cognitive responses toward eco-fashion can lead to their affective
responses of eco-fashion.
The Effects of Affective Responses and Cognitive Responses on Consumer Behavior
Tendencies
The results shown in Figure 6 demonstrate that consumers’ affective responses and
cognitive responses can positively influence their purchase intention toward and willingness to
pay more for eco-fashion. Moreover, the cognitive responses represent individuals’ thoughts, and
consumers’ cognitive responses toward eco-fashion have a very strong effect on purchase
intention. When consumers make purchase decisions, they are likely to make choices based on
cognitive elaboration of information (Epstein, 1993; Leventhal, 1994). For example,
environmentally significant information has a positive impact on consumer purchase behavior
such as purchase intention and willingness to pay more (Thogersen, 2000).
Individuals differ in their responses to situations such as eco-fashion purchasing, and their
behaviors are the result of an interaction between the rational and experiential processing
systems (Epstein, 1994). Some consumers engage in intuitive-experiential processes and base
their responses on their feelings and affect. Others engage in analytical-rational thinking
processes and base their responses on their thoughts and cognition. In other words, the analytical-
rational style has a cognitive basis and the intuitive-experiential style has an affective basis
(Epstein, 2003). This study proposes that both experiential and rational responses can positively
influence their behavioral tendencies for eco-fashion.
Implications
Theoretical Implications
This study integrates the simple information-processing model (Bettman, 1979) and
cognitive-experiential self-theory (Epstein, 1998) to delineate the hierarchical structure of
individual differences, responses, and consumer behavioral tendencies toward eco-fashion. In the
eco-fashion context, an individual is emotionally driven by her need for variety and fashion
interests, while she is logically driven by her concerns about environmental and social impacts
that are caused by the fashion production process (Bagozzi, Gopinath, and Nyer, 1999). The
individual receives a large amount of information daily from the marketer and uses simplifying
strategies such as focusing on ethical attributes to process information. The information flows
from input to storage and then output (Bettman, 1979). Moreover, the individual’s emotions are
cognitively based, and her positive feeling of eco-fashion can be encourage by emphasizing
cognitive responses of eco-fashion (Compeau, Grewal, and Monroe, 1998; Lazarus, 1991; Lin,
2004).
The model developed for this study has broadened the application of Bettman’s simple
information processing model and cognitive-affective self-theory. First, the results reveal that
affective responses and cognitive responses to eco-fashion are determined by individual
differences in need for variety, ecological consciousness, and social consciousness. The results
give empirical support for the hypotheses that consumers’ need for variety generates affective
responses and eventually purchase intention and willingness to pay more for eco-fashion.
Further, consumers’ ecological consciousness and social consciousness generate cognitive
responses and, eventually, purchase intention and willingness to pay more for eco-fashion.
Consumers’ cognitive responses positively influence their affective responses.
Second, the results provide empirical evidence of the cognitive-affective response
approach in an eco-fashion context. In an eco-fashion consumption context, emphasizing the
affective responses of eco-fashion is not enough because emotion-driven behaviors are typically
short in duration (Cohen, Pham, & Andrade, 2008) and emphasizing the cognitive responses is
very important because the cognitive responses toward eco-fashion can lead to positive affective
responses.
Moreover, when consumers doubt about the ecological and social benefits of eco-fashion,
when they view the eco-fashion as pricy, and when they consider that eco-fashion products do
not meet their aesthetic needs, they may feel cognitive dissonance that is the discomfort caused
by contradictory beliefs or ideas and relates to a situation involving conflicting attitudes, beliefs,
or behaviors (Armstrong & Kotler, 2013). However, when consumers’ behaviors are driven by
logic thinking, their cognitive dissonance can be reduced because consumers’ logic thinking can
lead to their favorable feelings toward eco-fashion and reduce their discomfort about
ecofashion’s high price and the lack of aesthetic design.
In summary, the IPO and CEST provide strong explanations for eco-fashion consumption
behavior and fill a gap in the literature by applying the information-processing model to the
ecofashion consumption context. Specifically, this study examines how an individual responds to
eco-fashion information by applying the IPO and CEST to achieve an understanding of the
hierarchical relationships among individual differences, experiential and rational system
responses, and consumer behavior tendencies.
Practical Implications
This study has offered several contributions that can benefit eco-fashion designers and
manufacturers who want to design and produce the right products for consumers as well as
marketers that want to promote eco-fashion effectively. To effectively promote eco-fashion,
marketers can encourage consumers’ desire for variety by emphasizing the innovative attributes
of eco-fashion offerings and diversifying the styles and designs of eco-fashion to enhance
consumers’ affective responses. Because consumers’ ecological consciousness is a particularly
important predictor of their cognitive responses, marketers can advertise ecological attributes of
eco-fashion such as low impact dyes to enhance consumers’ cognitive responses. Because
consumers’ rational system is more important than their experiential system in the eco-fashion
context, marketers can engage consumers to think about ways to improve the quality of life in
society, to enhance others’ lives, and to encourage consumers to carefully process eco-fashion
information. The positive cognitive responses can eventually enhance their affective responses
because consumers’ cognitive responses have a very strong effect on their affective responses.
Practical Implications: From Emotion-Driven Dispositions to Affective Responses
Individuals’ need for variety motivates them to make choices different from those of
others (Ariely & Levav, 2000). Specifically, innovative attributes of eco-fashion such as corn
fiber, biodegradable or renewable materials, and vegetable tanned organic leather can meet
consumers’ needs to try out new or different products.
Designers must understand consumers’ need for variety in relation to eco-fashion and use
innovative and environmental friendly materials to design clothing and to satisfy consumers’
variety needs. For example, Mademoiselle Chi Chi is a fashion clothing line made with Qmilch
that is a 100% natural and renewable fiber created from milk protein. The innovative features of
eco-fashion can satisfy consumers’ need for uniqueness and their need for change, and
consumers believe that they can get more pleasure by wearing eco-fashion products (Abraham,
2011).
Also, designers can use disposed products to design a new product to satisfy consumers’
need for novelty. For example, Teijin, a Japanese polyester supplier, offers Ecocycle
chemical recycling program for apparel and uses worn and unfashionable clothes to
make fashion apparel (NordicFashionAssociation, 2016). This innovative way of combining
fashion apparel and a solution to the growing problem of disposing worn and unfashionable
clothes makes Teijin Ecocyle a green fashion and meets consumers’ desire for variety and
curiosity to experience the unknown. When consumers buy eco-fashion made from Teijin’s
polyester, they support the meaningful environmental program and fulfill their desire for a
variety of new life experiences.
In addition, designers and manufacturers can engage consumers to learn what innovative
attributes they expect from eco-fashion. For example, designers and manufacturers can consider
holding eco-fashion story telling contests in virtual communities. Virtual communities on social
networks are the best place for consumers to interact with designers. By learning stories about
the features that consumers desire in eco-fashion, designers and manufacturers can diversify the
designs and styles of eco-fashion to satisfy consumers’ curiosity and reduce their boredom
associated with daily routines or a well-known product or brand (Chua, 2013).
Practical Implications: From Logic-Driven Dispositions to Cognitive Responses
Consumers’ logic-driven dispositions have stronger effects on their cognitive responses
and eventually their behavior outcome compared to the effects that their emotional-driven
disposition have on their affective responses. The results imply that humans’ rational system is
more important than the emotional system. Some consumers care about the environment, and
they buy eco-products, based upon their personal consumption decisions on the product’s
sustainability, and alter their behaviors in accordance with their green beliefs (Cho, Thyroff,
Rapert, Part, & Lee, 2013). Others care about social problems such as forced labor, low wages,
excessive hours of work, discrimination, and health and safety hazards in the workplace and take
active roles within their communities for social, political, and charitable causes (Kozer &
Connel, 2012). Thus, manufactures, designers, and retailers must understand and satisfy
consumers’ ecological and social concerns regarding eco-fashion to encourage their cognitive
responses. For example, Gaia Conceptions in Greensboro, NC produces and sells women’s
clothing dyed with natural materials or with less water and having a lower impact on the
environment (Busfield, 2014). The ecological and social attributes of eco-fashion such as being
made in USA and having less environmental impact can satisfy consumers’ ecological and social
concerns to provide better living conditions for other people, to support local business, and to
live up to their altruistic values of equality and social justice (Jägel et al., 2012). In other words,
eco-minded consumers have green beliefs and are willing to follow ethical standards. They like
to consume products and services that have a positive impact on the environment and the society.
Designers, manufactures, and retailers can help consumers to recognize the raw materials,
to understand the production processes of eco-fashion, and to engage consumers’ consciousness
processing to think about ways to improve the quality of life in society and others’ lives.
Specifically, an online video developed by a manufacturer and containing information on the
production processes of eco-fashion can be placed on a manufacturer’s or retailer’s website or on
YouTube so that the company can interact with consumers and share product messages with
consumers. For example, to help consumers to learn about the environmental and social benefits
of eco-fashion, Patagonia, a retailer with a long history of being eco-friendly, recently posted a
men’s eco-fashion video, which introduces information about the materials and the production
processes used for men’s eco-fashion, on YouTube (YouTube, 2014). Further, retailers can use
flyers with inspiring messages highlighting the ethical features of their products, and
manufacturers can use social advertising highlighting their policies such as no use of child labor,
no wasteful consumption, or no water pollution to attract ecological and social consumers’
attention and interest.
Practical Implications: From Cognitive Responses to Affective Responses
Individuals develop both cognitive and affective evaluations in relation to a particular
environment (Proshansky, Fabian, & Kaminoff, 1983). Some researchers have argued that
cognition precedes affective reactions (Lazarus, 1984; Oliver, 1980, 1981; Compeau, Grewal, &
Monroe; 1998). To effectively promote eco-fashion, marketers should encourage consumers’
cognitive responses toward eco-fashion by demonstrating the social benefits and ethical
attributes of eco-fashion because consumers’ cognitive responses have a very strong effect on
their affective responses.
A practical solution to enhance consumers’ cognitive responses is to encourage social
gatherings such as clubs or social organizations where manufacturers and retailers can interact
with consumers, tell them about the ethical attributes of eco-fashion such as made in USA, and
develop product connections with them. This is a way to create a place for consumers to gather
together, to share information about the environmental and social benefits of eco-fashion, and to
discuss their experiences with eco-fashion. For example, Nike has developed local running clubs,
online memberships, and online communities to introduce its Flyknit technology, which is a
sustainable innovation used in its shoes (NIKE news, 2012). Nike seeks to influence consumers’
responses toward its eco-products through its running clubs, the company’s website, or social
media sites.
Also, retailers can encourage their sales associates in brick and mortar stores to actively
introduce the eco-fashion items carried in the store along with the ethical and social benefits to
consumers to enhance their cognitive responses. In this way, consumers may develop an interest
in knowing more about eco-fashion and may become involved in eco-fashion.
Moreover, manufactures and retailers can publicize different eco-fashion items with
symbols indicating features such as the use of fair trade certified cotton or certified organic
cotton, being made in the USA, or using low impact dyes in magazines and on websites or social
media to help consumers identify the eco-symbols and to inform them about the benefits and the
variety choices available in eco-fashion. In addition, retailers and manufacturers can engage in
public relation efforts such as eco-fashion shows on television or in shopping malls and
ecofashion conferences or events to effectively inform consumers about eco-fashion and its
benefits.
Advertising, sales promotion, personal selling, public relation, and direct and digital
marketing are five major promotion tools and can be used separately or mixed to promote
ecofashion. In other words, marketers can use traditional media (TV, radio, and magazines), new
media (internet and social network), sales promotion, personal selling, and public relationships
(at conferences and events) to generate strong positive affective responses and to effectively
promote eco-fashion purchasing. This may be a particularly effective way because promoting
products on traditional media such as TV and radio is expensive and a large amount of
advertising information clusters together on TV and radio.
For example, retailers, manufacturers, or designers can sign up on Instagram or register
on Flickr to post new eco-fashion pictures with brief information on their products’ ecological
and social attributes. Ecouterre, a website devoted to the sustainable design of fashion products,
publishes photo essays on Instagram to emphasize innovative features of products and to
encourage consumers to share their stories and experiences about eco-fashion (Chua, 2016).
When consumers participate in web communication and learn about the variety of styles, the raw
materials, and the production processes involved in eco-fashion, their cognitive responses toward
eco-fashion can lead to their positive feeling toward eco-fashion. Specifically, consumers’
cognitive-experiential responses may be generated as they process “word of web” (word of
mouth on the web) and become aware of the varied features of eco-fashion.
Limitations and Future Research
This study has some limitations that lead to recommendations for future studies. First, the
focus group interview participants were nine undergraduate students in the Department of Retail,
Hospitality, and Tourism Management at the University of Tennessee. All nine participants were
females. The responses are gender biased. Although the researcher asked all nine participants to
think from the perspectives of male members in the family such as their brothers, fathers,
grandfathers, or boyfriends, the gender-based biases may still exist. Second, the CEST was
applied to the current study through the incorporation of individual differences as consumer
inputs. However, consumer inputs such as search activity and environmental inputs may have led
to particular kinds of responses. Thus, conductors of future studies may wish to employ different
consumer inputs such as search activity or type of involvement and environmental inputs such as
advertising. Third, the proposed model was tested in the eco-fashion context. Caution must be
exercised when generalizing these findings to other types of eco-products such office supplies or
accessories.
Future studies can consider other retail categories such as consumer products (laundry
detergents or soaps) and sustainable packaging of luxury goods (Tiffany or Gucci) that may
entail responses different from those related to eco-fashion. Further, the lack of support for one
of the proposed hypotheses suggests a direction for future research. In particular, this study failed
to find a relationship between fashion interest and affective responses. The absence of a
relationship between fashion interest and affective responses may be explained by the lack of
fashion sense in relation to eco-fashion. Future investigation should include a large number of
fashion oriented clothing pictures as visual stimuli.
Fourth, this study employed a self-report survey method whereby respondents were asked
to look at stimuli (eight eco-fashion pictures) and answer survey questions, based on the limited
number of eco-fashion pictures. To allow participants to have a comprehensive view of
ecofashion, future research could show a short video with audio and visual images of different
companies’ eco-fashion product lines.
Conclusions
The findings demonstrate that the model developed for this study can broaden the
application of the IOP model and CEST by revealing the hierarchical relationship among
individual differences and responses and consumer behavioral tendencies in the eco-fashion
context. The results indicate that consumers’ need for variety is an important predictor of their
affective responses toward eco-fashion and consumers’ ecological consciousness has a stronger
impact on cognitive responses than social consciousness does. Interestingly, the
analyticalrational system is more important than the intuitive-experiential system in the eco-
fashion context, and the cognitive-affective response approach is strongly supported in the eco-
fashion context. When consumers engage in a cognitive-affective response approach, their
cognitive dissonance is reconciled because consumers’ cognitive responses have a very strong
effect on their affective responses. Further, consumers’ affective responses and cognitive
responses positively influence their purchase intention toward and willingness to pay more for
eco-fashion. Based on the results obtained in the study, ways used to effectively promote eco-
fashion have been suggested for designers who want to design the right products for consumers as
well as manufacturers and retailers who want to promote eco-fashion effectively.
