QUALITATIVE RESEARCH DESIGNS

QUALITATIVE PARADIGM

Naturalistic paradigm

Soft science

Focus: usually broad

Holistic

Subjective

Reasoning: dialectic, inductive

Basis of knowing: meaning, discovery

Shared interpretation

Communication and observation

Basic element of analysis: words

Individual interpretations

Uniqueness

The “Logic” of Qualitative Research

  • Based on holistic view & following beliefs:

There is no single reality – reality is based on perceptions – it is different for each person – changes over time

What we know has meaning only within a given situation or context

The reasoning process in qualitative research involves:

- perceptually putting pieces together to make wholes

Philosophy and Qualitative Research

  • Frameworks are not used the same as in quantitative
  • The goal is not theory testing
  • Each study should be guided by a particular philosophical stance

  • Philosophical Stance assists to:

directs the question(s) that are asked

the observations which are made

the interpretation of data

DESIGN OF QUALITATIVE STUDIES

  • Specify design before data collection
  • Adhere to the design after study started
  • Study design evolves over time
  • Researcher Decisions include:

How to obtain

From whom to collect

How to schedule

How long

Design of Qualitative Research

  • EMERGENT DESIGN
  • A design that emerges as the researcher makes ongoing decisions reflecting what has already been learned

  • Lincoln & Cuba (1985) – not researcher laziness or sloppiness – but rather desire to base inquiry on realities and viewpoints of those under study
  • Key: realities and viewpoints that are NOT KNOWN or UNDERSTOOD AT THE OUTSET

Characteristics of Qualitative Research Design

Flexible, elastic, capable of adjusting

  • Merging together of various data collection strategies
  • Holistic, understand the whole
  • Research intensely involved
  • Research to become the research instrument
  • Requires ongoing analysis of data to formulate subsequent strategies and to determine when field work is done

What is “Bricolage?”

Qualitative Designs

  • PHASES of a Qualitative Study:

Orientation an overview

Focused exploration

Confirmation and closure

(Lincoln & Cuba, 1985)

Qualitative Design Features

  • Control over the independent variable

  • Type of group comparisons

  • Number of data collection points

  • Occurrence of the independent & dependent variables

Qualitative Research Traditions

  • Four traditions described by nurse researcher:

Ethnography

Phenomenology

Grounded Theory

Historical Research

ETHNOGRAPHY

  • Research tradition in anthropology
  • Provides a framework for studying meanings, patterns, and experiences defined by a cultural group in a holistic fashion

  • Ethnoscience (Cognitive Anthropology): focuses on the cognitive world of a culture – semantic rules and shared meanings that shape behavoir

ETHNOGRAPHY

  • Focus: the culture of a group of people
  • Assumption: every human group evolves a culture that guides members view of the world and the way they structure their experiences

  • At times referred to as “macroethnography: - able to study broadly defined cultures

  • At times referred to as “microethnography” – able to study cultures using a very narrow focus

Ethnography Cont’d

  • Aim: to learn from rather than study members of a cultural group

  • Two perspectives:

Emic – insider’s view, the way the members of a culture envision their world

Etic - outsiders’ interpretation of the experiences of that culture – strive to get at cultural experiences that members do not talk about or may not even be consciously aware

Ethnography Cont’d

  • Extensive field work
  • Typically labor intensive
  • Time consuming

  • Researcher as instrument - to study a culture it requires a certain level of intimacy – needs to be developed – become one within the culture

Ethnography Cont’d

  • Three types of information:

Cultural behavoir

Cultural artifacts

Cultural speech

Sources of information – in-depth interviews, records, charts, observations and other types of physical evidence are used

Ethnography Cont’d

  • Products of this research includes:

rich and holistic descriptions

describe normative behavoir and social patterns

Information about health beliefs and health practices

Facilitates an understanding of behavoirs affecting health and illness

Leininger coined the phrase:

“ethnonursing research” –the study and analysis of local or indigneous people’s viewpoints, beliefs and practices about nursing care behavoir and processes of designated cultures

Phenomenology

  • Phenomenology is both philosophy and a research method
  • Purpose of this research method is to describe experiences as they are lived – to capture the

“lived experience”

  • Developed by Husserl & Heidegger – an approach to thinking about people’s life experiences.

Phenomenology Cont’d

Philosophical Orientation

view the person as integral with the environment

World is shaped by the self and also shapes the self

The person is a self within a body

Person is referred to as “embodied” – our bodies provide the possibility for the concrete actions of self in the world

The body, the world and the concerns, unique to each person, are the “context” within which that person can be understood

“being in time”

Phenomenology Cont’d

  • A phenomenological researcher asks the question:

“What is the essence of this phenomena as experienced by these people and what does it mean?”

Assumption: there is an “essence”

an essential variant structure

Investigates subjective phenomena

Belief that truths about reality are grounded in peoples’ lived experiences

Phenomenology Cont’d

  • Two Schools of Thought:

Descriptive phenomenology

Interpretive phenomenology (hermeneutics)

Phenomenology Cont’d

  • Four aspects of the lived experience:

SPATIALITY

CORPOREALITY

TEMPORALITY

RELATIONALITY

Phenomenology Cont’d

  • Phenomenologists believe – human existence is “meaningful” and “interesting”
  • “Being in the world” or “Embodiment” is a concept that acknowledges people’s physical ties to their world
  • People:

THINK

SEE

HEAR

FEEL

CONCIOUS OF THEIR BODIES INTERACTION WITH THE WORLD

Phenomenology Cont’d

  • Data sources:
  • In-depth conversations
  • Researcher helps the participant to describe lived experiences without leading the discussion
  • Two or more interviews/conversations are needed
  • Usually small number of participants (ie. 10 or less)
  • May use participation, observation and introspective reflection

Phenomenology Cont’d

  • Methodological Interpretations Used:

BRACKETING

INTUITING

Grounded Theory

  • Is an inductive research technique developed for health-related topics by Glaser & Strauss (1967)

  • Emerged from the discipline of sociology

  • “Grounded” – means the theory developed from the research is grounded or has it roots in the data from which is was derived

Grounded Theory Cont’d

  • Philosophical Orientation:
  • Based on symbolic interaction theory
  • Explores how people define reality and how their beliefs are related to their actions
  • Meaning is expressed through – symbols – such as words, religious objects, and clothing
  • Symbolic meanings are different for each of us
  • In social life - meanings are shared by groups – socialization process
  • Group life is based on consensus and shared meanings

Grounded Theory Cont’d

  • Is an approach to study the social processes and social structures

  • Focus: is the evolution of a social experience – the social and psychological stages that characterize a particular event of process

Grounded Theory Cont’d

  • Methodology:

does not begin with a focused research question

the question emerges from the data

fundamental structure feature –

is the “data collection”

is the “data analysis”

Is the sampling of participants occurs simultaneously

This procedure is referred to as “constant comparison”

Grounded Theory Cont’d

  • Constant Comparison: is used to develop and refine theoretically relevant categories and to identify the basic problem
  • Categories that are elicited from the data are constantly compared with data obtained earlier so that “commonalities” and “variations” can be determined
  • Categories can be “condensed” and “collapsed”

Grounded Theory Cont’d

  • Data Sources:

in-depth interviews are most common

Observational methods

Existing documents

Usually a sample of 25 to 50 informants

Has contributed to the development of middle range nursing theories

Historical Research

  • Historiography examines events of the past
  • Historians believe the greatest value of historical knowledge is an increased self-understanding

  • Philosophical Orientation:
  • A very old science
  • Primary question “Where have we come from, who are we, and where are we going?”
  • Myths, past, present and future are not distinguishable
  • Myths are a form of story telling

Historical Research Cont’d

  • History moves beyond the myth
  • Chronicling events, deeds, victories and stories about people and civilizations
  • Comparing histories, identifying patterns

  • Aim:
  • to discovery new knowledge
  • Seeking to answer questions concerning causes, effects and trends relating to past events
  • To shed light on present behaviors and practices

Historical Research Cont’d

  • Assumptions:

There is nothing new under the sun

One can learn from the past

Sampling in Qualitative Research

  • Usually small, non-random samples
  • Concern: measure attributes and relationships in a pop’n
  • Need a representative sample

  • Aim: to discover meaning, uncover multiple realities, therefore generalization is not a guiding criteria

Sampling in Qualitative Research

  • Types of sampling:

Convenience sampling

Snowball sampling

Theoretical sampling

Purposeful sampling – several strategies – maximum variation sampling, extreme/deviant case sampling, and typical case sampling

Simple random

Sample Size

  • No firm establishment of criteria or rules
  • Should be determined on the basis of informational needs

  • Is largely a function of:

the purpose of the inquiry

the quality of the informants

The type of sampling strategy used

Sample Size

  • Guiding Principle is that of,

  • DATA SATURATION: sampling to the point at which no new information is obtained and redundancy is achieved

Critiquing the Sampling Plan

  • Evaluate the sample plan based on the following:

Terms of its adequacy

Terms of its appropriateness

Adequacy means –

Appropriateness means -

Assessment of Qualitative Data

  • Need to address validity and reliability
  • Do the measures used by the researcher yield data reflecting the truth?

  • Lincolon & Cuba (1985) – four criteria:

Credibility

Dependability

Confirmability

Transferability

(criteria for establishing “trustworthiness”)

Assessment of Qualitative Data

  • Credibility – refers to confidence in the truth of the data

  • Prolonged engagement
  • Persistent observation
  • Triangulation
  • External checks – peer debriefing & member checks
  • Researcher credibility

Assessment of Qualitative Data

  • Dependability – refers to data stability over time and over conditions

  • Steps to approach:

Stepwise replication

Inquiry audit

Assessment of Qualitative Data

  • Confirmability –refers to the objectivity or neutrality of the data – what does that mean?
  • AUDIT TRAIL:

  • Transferability – refers to the extent to which the findings from the data can be transferred to other settings or groups = similar to the concept of generalizability
  • THICK DESCRIPTION:
