Abstract

Increasing individual subjective well-being has various positive outcomes, knowledge about

its antecedents and the mediators of this relationship can therefore help to increase subjec-

tive well-being and the accompanying positive effects. The more future oriented facets of

psychological capital, i.e. optimism, hope and self-efficacy have been shown in several stud-

ies to be positively related to subjective well-being and negatively to ill-being. Furthermore,

recent studies suggest coping strategies as mediators for these relationships. In our study,

we examined the longitudinal relation of optimism, hope and self-efficacy with subjective

well-being and ill-being in a German panel dataset and tested the mediating effect of flexible

goal adjustment in a path model. Our results show a statistically significant positive effect of

self-efficacy and optimism on subjective well-being as well as a statistically significant nega-

tive effect of optimism on depression over three years. All three predictors show a statisti-

cally significant relation with flexible goal adjustment, but flexible goal adjustment did not

mediate the effect on subjective well-being or depression.

Introduction

Happy workers will be more productive workers—as Cropanzano and Wright [1] acknowl-

edge, this relation has been supported if happiness was operationalized as well-being, although

the happy-productive worker hypothesis [2] has been subjected to much debate and produced

controversial empirical results [3]. To learn about mechanisms that increase well-being is rele-

vant in the work context as well as independent of the context [4]. It is relevant for the individ-

ual itself, but also, according to the happy productive worker hypothesis, for organizations.

Numerous theories have set out to explain how various individual or job characteristics

influence well-being (for an overview see [5]), e.g. the conservation of resources theory [6], the

job-demands-resources theory [7] or the stressor-detachment model [8]. According to the con-

servation of resources theory [6], individuals seek to acquire and maintain resources. Their gain

or maintenance results in well-being [9]. Hobfoll [6] distinguishes four types of resources that

have the potential to increase well-being: physical objects, conditions, energies or personal char-

acteristics [9]. In our study we focus on personal characteristics and more specifically on charac-

teristics proposed by positive psychology, as well-being can be enhanced by interventions

protection, signing a data distribution contract is

targeting on these constructs [10]. More specifically we examine the longitudinal effects of self-

efficacy, optimism and hope on well-being. Coping strategies are being discussed to function as

mediating mechanisms of this relation [11]. Flexible goal adjustment as one coping strategy has

been shown to mediate the relationship between optimism and well-being in a concurrent sam-

ple [11]. We therefore also examine if flexible goal adjustment mediates the relation between

the three facets optimism, hope and self-efficacy with well-being over time.

Positive organizational behavior: Self-efficacy, optimism and hope

Positive psychology in the workplace encompasses various concepts [12] such as positive orga-

nizational behavior or positive organizational scholarship. They are united in their focus on

strengths and flourishing [13, 14] but have differing perspectives. The focus of positive organi-

zational behavior is on the individual within the organization. Luthans [15] defines micro-

level positive organizational behavior as the “study and application of positively oriented

human resource strengths and psychological capacities”(p59). Positive organizational behavior

in this sense is measurable and meets the open-to-development criterion. It is therefore open

to individual learning and change [15–17]. Three of these positive organizational behavior

capacities are self-efficacy, optimism, and hope. They all “fit the specific criteria of being posi-

tive, unique, measurable, capable of being learned and developed, and manageable for perfor-

mance improvement”([15] p70). All three are part of the overarching concept of Psychological

Capital (PsyCap) [18, 17], including resiliency besides self-efficacy, optimism, and hope. Psy-

Cap was developed as a work-related concept and, as a whole, is defined as “a core psychologi-

cal factor of positivity in general, and POB criteria meeting states in particular, that go beyond

human and social capital to gain a competitive advantage through investment/development of

‘who you are’” ([18] p253). PsyCap influences a variety of outcomes, such as job satisfaction

and commitment [19, 20] or reduced absenteeism [21]. Furthermore, individuals high in Psy-

Cap perform better than those low in PsyCap since they can draw upon more resources to pur-

sue goals [22, 23]. Furthermore, PsyCap is linked to an improved psychological and physical

well-being [24]. Of the four PsyCap components especially self-efficacy, optimism and hope

are goal- and future oriented.

Self-efficacy is a dispositional resource used for coping with all kinds of demands and

challenges [25, 26] and can be defined as “one’s beliefs about his or her ability to mobilize

the motivation, cognitive resources, and courses of action necessary to execute a specific

action within a given context”([27] p66). Optimism as conceptualized within the concept of

PsyCap [28] includes not only the dispositional optimistic look towards the future, but also

global positive expectations [29, 30]. Following Seligman [14], not only this positive outlook

but also the personal reflection of positive and negative events in the past, present and

future relevantly influence optimism [30]. Optimistic persons expect positive things to hap-

pen and therefore believe in a positive future [31, 32]. Hope is “a positive motivational state

that is based on an interactively derived sense of successful agency (goal directed energy)

and pathways (planning to meet goals)”([33] p287). Hopeful individuals are able to generate

alternative routes in an adaptive way [34, 35]. Goal-directed thoughts lead to positive and

active emotions (e.g. curiosity) or negative and passive emotions, depending on past experi-

ences with goal pursuits [36, 35]. Hopeful individuals use the ‘willpower’ to generate per-

sonal goals and resolutely follow them and the ‘waypower’ to adapt alternatives while

obstacles occur on their way [37]. There has been a lot of research regarding the distinction

of optimism and hope [38–42], and while being overlapping and having trait-like thoughts

about goals in common [41], their differential relations with outcomes suggest that they are

still distinct constructs [39, 43].

Subjective well-being, ill-being and positive organizational behavior

All three, self-efficacy, hope, and optimism have shown to be related to or predict well-being as

well as ill-being. One way of operationalizing well-being is via subjective well-being, which is a

multifaceted construct, consisting of affective and cognitive components [44]. It is not only associ-

ated with but can also lead to health and longevity [3, 45, 46], increase work-related productivity

and success [47], and positively influence social relationships [45, 48]. In contrast to well-being is

the term ill-being, which refers to negative psychological constructs such as depression [49]. For

the examination of the effects of positive organizational behavior both aspects seem to be relevant,

the prevention of ill-being as well as the promotion of subjective well-being, as the absence of ill-

being does not automatically lead to subjective well-being and vice versa [50].

Self-efficacy as “the power of believing you can” [51] correlates to and influences well-being

positively [25, 52–56], and reduces depression [57–59]. Optimism influences the way people

feel and how they actively try to solve problems when being confronted with obstacles and

hence influences subjective well-being [60–62]. Practicing optimism leads to increased well-

being [63]. Hopeful individuals are motivated to energetically pursue goals and to consider

alternative routes to achieve them [37]. They “generate more effective coping strategies to set-

backs due to pathways thinking, and thus experience more positive emotions which”([37]

p295) and this enhances their well-being. Accordingly, in their meta-analysis and review,

Reichard et al. [37] found statistically significant effect sizes between hope and job satisfaction

and well-being and negative effect sizes between hope, stress, and burnout.

So far, no study compared the effects of these three central constructs of positive psychol-

ogy. PsyCap is the only exception, but it is mostly examined as g-factor, effects of its subfacets

are seldom shown. PsyCap also has statistically significant relations to well-being [64] and pre-

dicts subjective well-being within a three-week period [65]. According to previous research on

self-efficacy, optimism and hope with well-being and ill-being, we propose:

(1) Self-efficacy (a), optimism (b) and hope (c) at T0 positively predict subjective well-being

at T1.

(2) Self-efficacy (a), optimism (b) and hope (c) at T0 negatively predict depression scores at T1.

Flexible goal-adjustment as a mediator

Goal regulation strategies have been frequently discussed as possible mediators between opti-

mism and well-being [11, 66, 67]. The results of Hanssen et al. [11] suggest that especially flexi-

ble goal adjustment applies as a mediator in this relationship. Flexible goal adjustment can be

seen as passive accommodative coping, as changing personal preferences due to situational

restrictions, which seems to be especially relevant in later life [68]. It is complementary to tena-

cious goal pursuit, an assimilative coping strategy, in which life circumstances are adjusted to

obtain a desired condition [68]. The flexible management of personal goals is associated with

well-being [69–73]. Goal regulation strategies such as flexible goal adjustment were found to

affect the quality of life and general well-being of patients with chronic illnesses [74, 75]. Fur-

thermore, in older age flexible people report higher levels of self-esteem [76] and are more

likely to look at their biographical past in a self-enhancing way [77]. By disengaging old goals

when necessary, reengaging new goals and accepting this change by adjusting to the situation,

people can stay optimistic and hopeful despite witnessed difficulties and are more satisfied

with their lives [68, 71]. At first sight, high self-efficacy should inhibit flexible goal adjustment,

in a sense that if one is certain about one’s possibilities, there is no need to change a goal. But

as Brandtstädter ([78] p143) argued, it might not be that simple, as “if getting what one wants

is central to the concept of power, it follows that a way to retain a sense of efficacy may be to

adjust one’s preferences to the range of the feasible”. Following this argumentation, the rela-

tion of self-efficacy and subjective well-being as well as depression, should also be mediated by

flexible goal adjustment.

We therefore propose:

(3) Flexible goal adjustment mediates the effect of self-efficacy (a), optimism (b) and hope

(c) at T0 on subjective well-being at T1.

(4) Flexible goal adjustment mediates the effect of self-efficacy (a), optimism (b) and hope

(c) at T0 on depression at T1.

Method

Participants and procedure

Data for this study comes from the German Ageing Survey [79], an ongoing register-based,

cohort-sequential, nationwide representative survey of the German population aged 40 to 85.

The present study used the sample of 2008 (6205 participants) and 2011. In 2011, 2858 partici-

pants of the original sample were re-interviewed with a response rate of 64.4%. The response

rate corresponds to that of other longitudinal studies with comparable age groups [80]. Partici-

pants completed face-to-face interviews and a self-administered questionnaire. Due to the lon-

gitudinal data analysis only people who were interviewed 2008 and 2011, with employment

status working and maximum age 65 (maximum retirement age in Germany) were included.

These criteria excluded 1858 persons from the data analysis. Furthermore, 408 were excluded

due to missing data (345 due to declined answers on relevant variables, 63 due to high amount

(> 50%) of missing data scale wise). The total sample included 592 people between 39–62

years of age in 2008 (M = 49.43, SD = 5.60), and nearly half of them (47%) were men.

Measures

Self-Efficacy was measured using the Generalized Self-Efficacy Scale [81]. The scale consists of

5 items (e.g. “I can usually handle whatever comes my way”) with a 4-point Likert response

format (Cronbach’s α2008 = .79; α2011 = .79). Optimism was measured using the ‘Affective valence of future time perspective’ scale [82].

The scale consists of five items (e.g. “I look to the future with confidence”) with a 4-point

Likert response format (Cronbach’s α2008 = .86; α2011 = .86). Hope was measured using the Hope Scale [83]. The scale consists of 8 items (e.g. “There are

lots of ways around any problem”) with a 4-point Likert response format (Cronbach’s α2008 = .83; α2011 = .83).

Flexible goal adjustment was measured using the Flexible Goal Adjustment Scale [84]. The

scale consists of 10 items (e.g. “I adapt quite easily to changes in plans or circumstances”) with

a 5-point Likert response format (Cronbach’s α2008 = .77; α2011 = .77). Subjective well-being was composed of the three factors positive affect, negative affect, and life

satisfaction [44]. The affective component of subjective well-being was measured using the German

version [85] of the brief Positive Affect Negative Affect Scale (PANAS) [86]. The scale consists of 10

items, 5 negative adjectives (e.g. “ashamed”, Cronbach’s α2008 = .87; α2011 = .86) and 5 positive adjec- tives (e.g. “enthusiastic”, Cronbach’s α2008 = .85; α2011 = .86) with a 5-point Likert response format.

The cognitive component of subjective well-being was measured using Satisfaction with

Life Scale [87]. The scale consists of 5 items (e.g. “I am satisfied with my life”) with a 5-point

Likert response format (Cronbach’s α2008 = .84; α2011 = .85).

Depressive symptoms were measured using the General Depression Scale (Allgemeine

Depressions Skala) [88]. The scale consists of 15 items (e.g. “I felt that everything I did was an

effort”) with a 4-point Likert response format (Cronbach’s α2008 = .85; α2011 = .87). More details on the questionnaires used can be found at www.dza.de/en/research/deas/

Covariates / Control variables

Sex is an important covariate for subjective well-being, as it has been revealed that especially

older women reported lower subjective well-being [89] and there are differential relations for

sex between our predictors and subjective well-being [37]. Income and education are positively

related to subjective well-being [90]. The socio-economic status (SES) in general affects physi-

cal and psychological health negatively [91, 92]. SES is assessed by the individual´s occupation

and classified with the International Socio-Economic Index of Occupational Status (ISEI),

which scales occupations by relating them to education and income [93]. SES influences sub-

jective well-being and health through different ways: Low SES groups show higher health risk

behavior [94], have less access to health care and receive qualitatively poorer health care [95],

the material deprivation is higher and the psychosocial environment is more stressful over the

life course [96]. Further we included the occurrence of special health events such as an accident

or a serious illness due to the possible impact of these events on subjective well-being and

depression [97].

Data analysis

We checked the demographic data for effects of systematic drop-outs due to the large gap

between complete and final data set for our analysis. Only minimal changes in age, sex and the

distribution of individuals in East and West Germany could be found.

As subjective well-being consisted of three independently measured constructs, we tested

for the unidimensionality of the compound variable using confirmatory factor analysis. The

Satorra-Bentler adjusted χ2 was calculated to adjust for non-normal distributions of the vari- ables [98]. The fit was inspected using the criteria proposed by Hu and Bentler [99]. According

to these indices the model for subjective well-being in 2008 (Satorra-Bentler-χ2 (1, 592) = .025, p = .874, CFI = 1.00, SRMR = .003, RMSEA = .00, CIRMSEA = .00 - .06) as well as the model for

SWB in 2011 (Satorra-Bentler-χ2 (1, 592) = .052, p = .820, CFI = 1.00, SRMR < .001, RMSEA < .001, CIRMSEA = .00 - .06) showed a good model fit. To test our hypotheses we used a struc-

tural equation model (SEM). The data analysis was run using the statistical software R [100].

The confirmatory factor analyses and SEM were conducted using the “lavaan” package [101].

Results

Table 1 offers a general overview over the bivariate correlations of all variables used in this

study. The path model to test our hypotheses shows an acceptable model fit, Satorra-Bentler-

χ2 (5, 592) = 17.952, p = .003, CFI = .979, SRMR = .015, RMSEA = .066, CIRMSEA = .037 - .098. Fig 1 shows the tested model with highlighted statistically significant paths while all direct

regression paths of the model are displayed in Table 2. Self-efficacy and optimism at T0 both

statistically significantly predict subjective well-being at T1, but only optimism at T0 shows sta-

tistically significant negative relations to depression at T1. Hope at T0 shows no statistically sig-

nificant relation to either subjective well-being or depression at T1. Hypotheses 1(c) and 2(c)

therefore have to be rejected.

Whereas all three predictors are statistically significantly related to flexible goal adjustment

at T0, no indirect path is statistically significant with standardized regression paths between

.002-.01. These results are not in favor of hypotheses 3 and 4.

Discussion

Positive organizational behavior focuses on individual strengths and resources [15], optimism,

hope and self-efficacy being prominent examples. All three are related to positive aspects from

an individual perspective but also from an organizational perspective. We therefore wanted to

examine if those three aspects have a longitudinal relation with subjective well-being and ill-

being and if this relation is mediated by the coping strategy flexible goal adjustment. For our

study we used a working subsample of the German Ageing Survey [79].

In accordance with other studies, our results show that all three facets are correlated to sub-

jective well-being and depression concurrently [38, 102, 103]. According to the results of our

path model, hope seems not to be relevant for time-lagged subjective well-being nor depres-

sion, but optimism predicts both and self-efficacy predicts subjective well-being after a three

year period. Hence, in a direct comparison, optimism seems to be the most relevant for subjec-

tive well-being and depression of the three constructs.

One reason for the diminishing effect of hope could be the chosen outcome criterion. Bry-

ant and Cvengros [39] argue that optimism focuses more on broader quality of future out-

comes whereas hope focuses more on specific goals. As well-being in our study with the two

components of affect and general life satisfaction presents rather a general positive than a goal-

specific outcome, our results are in accordance with their argument. This applies accordingly

for our second outcome variable depression. On the other hand, our results also raise the ques-

tion if the impact of hope diminishes because optimism and self-efficacy have too much

overlap with the waypower and willpower components of hope [33]. In the study of Bryant

and Cvengros [39] for example, as well as in other studies [103] the three variables are highly

correlated. Bryant and Cvengros [39] argue that hope and optimism have discriminant rela-

tions with other variables, but can also be considered as having a common g-factor. The meta-

analytical results in the study of Alarcon et al. [38] accordingly point out, that optimism and

hope are distinguishable but related and that they have discriminant relations with outcome

variables, with optimism being more relevant in situations with low personal control and hope

being more relevant in situations with higher personal control. Further research with different

outcome variables is therefore needed to clarify if hope in comparison to optimism has more

impact on time-lagged rather goal specific outcomes.

Our results are also in line with Benyamini and Roziner [104] who found a statistically

significant relation between optimism and self-rated health on life satisfaction after a five

year period. In their study this relation was eliminated when affectivity was included in the

analysis. In our study, however, affect is a part of the outcome as the broader concept of sub-

jective well-being includes life satisfaction as well as positive and negative affect. Optimism

might therefore be more responsible for the variance in the affective part of our subjective

well-being measure.

Self-efficacy was also related to subjective well-being over a three year period in our sample.

This is in support of previous studies that see self-efficacy as an important factor for well-being

[53]. However, we found no relation with ill-being. Although depression goes in hand with

lower levels of self-efficacy [105], higher levels of self-efficacy seem not to impact levels of

depression significantly. This result contradicts the findings of Holahan and Holahan [58] and

Maciejewski et al. [59]. It should be stated though, that the study of Holahan and Holahan [58]

focuses on self-efficacy for social support. Social support on the other hand also has an impact

on depression [58, 106]. Maciejewski et al. [59] examined general self-efficacy. Their effect size

for the indirect effect of baseline self-efficacy on follow-up depression for the subsample with-

out prior depression (βindirect = -0.114, s.e. = 0.033, p < 0.001) resembles ours (βindirect = -0.095, s.e. = 0.066, p = 0.153), but Maciejewski et al. [59] have a much larger sample. Further- more, overlaps between hope, optimism and self-efficacy have been controlled for in our sam-

ple, which might reduce the effect of self-efficacy. Taken together, the results suggest that there

is a possible small effect of self-efficacy on later depression.

Concurrently, optimism, hope and self-efficacy were all correlated with flexible goal adjust-

ment. Contrary to the results of Hanssen et al. [11] however, flexible goal adjustment did not

mediate the relation between optimism and self-efficacy with well-being nor with depression

over a three-year period. Hence, flexible goal adjustment might have cross-sectional assoca-

tions with well-being [11] but no long-time mediating effect.

The substantially long period of time (three years in our study) might be a drawback as

adjusted goals might rather be accepted as new goals. In order to examine the mediating effects

of flexible goal adjustment in the relation of positive organizational behavior and subjective

well-being respectively ill-being, longitudinal designs with shorter time periods could therefore

be appropriate. Furthermore, tenacious goal pursuit [66] might be an alternative for the long-

time mediation, as the modification of behavior or the situation in order to fit with one’s goals

might rather be the appropriate long-term strategy resulting in higher levels of subjective well-

being and lower levels of ill-being. Following the argumentation of Heyl, Wahl, and Mollen-

kopf [72] both flexible goal adjustment and tenacious goal pursuit are necessary for an adaptive

self-regulation and both have differential effects on the affective aspects of subjective well-

being. In order to get a complete picture, both aspects as well as their interactions should be

considered.

Practical implications

Subjective well-being has many desirable effects on a personal but also on the organizational

level (e.g. health and longevity, [45], or work-related productivity, [47]). Knowing about ante-

cedents of subjective well-being, and especially about developable factors is therefore helpful

in many ways. Positive organizational behavior subsumes developable factors that have an

effect on organizational well-being, optimism, hope and self-efficacy being among them.

There are intervention programs, even online interventions, in order to develop these facets,

e.g. the interventions to strengthen psychological capital [107, 20], that can support subjective

well-being and reduce ill-being. Focussing especially on optimism and self-efficacy can help to

develop easy to handle and little time-consuming interventions and strengthen the organiza-

tions following a people-based approch as e.g. described by Manuti and de Palma [108].

Furthermore, subjective well-being has an impact on the retention intentions of older

workers [109]. Supporting an optimistic outlook and self-efficacy in older workers might

therefore be one part of the puzzle to retain them in the active workforce in order to face the

demographic change. One has to bear in mind, however, that optimism and self-efficacy do

not inherently have a positive effect, but that this effect depends on the context [110]. There-

fore, “the best interventions to promote well-being may thus be those that teach people differ-

ent skills [. . .] and the best time and place to use each one” ([111] p577).

Limitations

As we used the panel data of the German Ageing Survey [79], we were restricted in our mea-

sures as well as in the age range of our participants. We had to rely on the measures used in the

German Ageing Survey and they proved to have satisfying internal consistency scores, but we

have to point out, that our results only hold for the measures used. Other measures that focus

on different aspects might yield different results [38]. Furthermore, our results are specific for

an older population. As we mentioned, certain coping strategies might be more relevant in

later life [78, 68], implications for younger populations therefore cannot be deviated and need

further research.

Also we used context-free measures of well-being. Referring to the happy-productive

worker hypothesis, and the remarks made by Cropanzano and Wright [1], these overall mea-

sures of well-being have an impact on work outcomes. This relation is empirically supported

e.g. by Tsai, Chen, and Liu [112] or Fritz and Sonnentag [113] (see also [114]). One has to

note, however, that the effects are smaller than those between context-specific measures and

work performance. All in all, context-specific and context-free measures of well-being are

overlapping to a large extent [44], which is especially the case for the working context as work

takes a large amount of time. Investing in possibilities to enhance general well-being should

pay off for organizations. Furthermore, the work context can be a place full of opportunities in

order to enhance self-efficacy.

Another possible limitation of this study is the issue of self-report measures and common

method variance [115]. This issue is heavily debated in work and organizational psychology

with unclear results if common method is in fact a problem to the results in this field or how

big the problem might be [116–119]. Even with the open debate we think that it is worth men-

tioning that it could be a possible limitation.
