The mediating role of work-to-family conflict in the relationship between shiftwork and depression

Abstract

With significant segments of the working population involved in shiftwork, there is the possibility of serious health outcomes. There are two possible pathways to ill health. In the biological pathway the body's circadian rhythms are affected, leading to physiological disturbances and the inability to cope. By contrast, the aim of this study is to elucidate a social pathway by which shiftwork may lead to mental ill health. It examines the mediating influence of work-to-family conflict in the association between shiftwork and depression. Gender differences are also investigated. The sample included 2,931 Canadian respondents with a spouse and at least one child living at home. Close to 28% of respondents were involved in some form of shiftwork. Structural equation modelling supported partial mediation through work-to-family conflict. Further analyses found that mediation was supported in sub-samples of male and female respondents. The results, however, suggest that the experience of shiftwork is quite similar for men and women as no significant differences were found between mediating models. Overall, the findings support the social explanation of the effect of shiftwork on mental health, but they do not rule out other social or biological pathways.     

Work hours and well-being: The roles of work-time control and work-family interference

This study focused on mediating and moderating processes underlying the relationship between work hours and well-being. Questionnaire data from 292 female employees in two UK public sector organizations were analysed. Drawing on effort-recovery theory and published empirical findings, it was hypothesized that work-family interference (WIF) would mediate the relationship between work hours and measures of well-being (psychological distress and family satisfaction), and that work-time control would moderate the association between work hours and WIF. Hierarchical regression analyses showed that, after controlling for demographic variables, neuroticism, and job demands, WIF mediated the effect of work hours on family satisfaction, although no evidence of mediation was found for the psychological distress outcome measure. Work-time control moderated the relationship between work hours and WIF; higher control buffered the effect of longer hours on WIF. These findings add to the literature on the role of WIF in the effort-recovery process by showing that longer work hours are not necessarily associated with higher work-family interference, and hence with poor recovery and impaired well-being. Instead, having a degree of control over work hours moderates the first link in this process. Thus, the provision by employers of some flexibility and control over work hours may help to reduce the potential negative impact of long work hours on employees.     

Measurement of negative affectivity: A comparison of self-reports and observer ratings

Abstract

Both self-report and non-self-report measures (co-worker ratings) of negative affectivity (NA) were obtained. Based on previous research, it was hypothesized that these two measures of NA would be moderately correlated. It was also expected that self-report measure of NA would be more strongly correlated with self-reported stressors and strains than would the co-worker measure. Finally, it was predicted that statistically controlling for self-reported NA would attenuate stressor-strain correlations more than would controlling for co-worker ratings of NA. A sample of 121 full-time employees who were pursuing graduate degrees completed self-report measures of stressors, strains, and negative affectivity. These individuals also asked two co-workers to assess their level of negative affectivity. Results supported all three hypotheses. Specifically, there was modest convergence between self-reported and co-worker NA. In addition, self-reported NA was more strongly correlated with self-reported stressors and strains than was the co-worker NA measure. Finally, statistically controlling for self-reported NA attenuated stressor-strain correlations much more than controlling for co-worker NA. These results suggest that observer ratings may be of some use in future NA research. Other implications of these findings are discussed.     

Evidence for the need to distinguish between self-initiated and organizationally imposed overload in studies of work stress

This study attempts to enhance our understanding of the inconsistencies reported in the literature concerning the relationship between work overload and work outcomes. We tested the proposition that work overload should be divided into two constructs based on its source: self-initiated overload (SIO), and organization-imposed overload (OIO). Based on the work stress and job crafting literatures, we expected that SIO and OIO would tend to relate differentially to the work outcomes of job satisfaction, emotional exhaustion, work–family conflict, job performance, and helping organizational citizenship behaviours. A study was conducted using three samples, the first consisting of full-time employed students in three countries (N?=?116), the second consisting of the nursing staffs of six private hospitals in Switzerland, and the third consisting of 161 middle manager–supervisor dyads in Switzerland. Two different measures of SIO and OIO were used. SIO was found to have a more beneficial relationship with the work outcomes than OIO, general supporting our hypothesis. Theoretical and practical implications are discussed.     

It's all about me: The role of narcissism in exacerbating the relationship between stressors and counterproductive work behaviour

Although studies have found that personality variables moderate the relationship between stressors and counterproductive work behaviour, few have examined the role of narcissism and those that did have found inconsistent results. Using a sample of 515 United States employees, we found that narcissism moderated the relationships between interpersonal conflict at work and counterproductive work behaviours directed at others, and between organizational constraints and counterproductive work behaviours directed at the organization, making both relationships stronger for those high on narcissism. We also found that narcissism moderated the relationship between organizational constraints and counterproductive work behaviours directed at others. Further, we demonstrated that the grandiose exhibitionism facet of narcissism moderated these same stressor–counterproductive work behaviours relationships, whereas the facets of leadership/authority and entitlement/exploitiveness did not. Our study indicates that organizational scholars should examine narcissism as an important antecedent of work behaviour, and that research needs to consider potential differential prediction by each of its facets.     

Effects of vacation from work on health and well-being: Lots of fun,quickly gone

Abstract

Although vacation from work provides a valuable opportunity for recovery, few studies have met the requirements for assessing its effects. These include taking measurements well ahead of the vacation, during the vacation and at several points in time afterwards. Our study on vacation (after-) effects focused on two related questions: (1) Do health and well-being of working individuals improve during a vacation? and (2) How long does a vacation effect last after resumption of work? In a longitudinal study covering seven weeks, 96 Dutch workers reported their health and well-being levels two weeks before a winter sports vacation, during vacation and one week, two weeks and four weeks after vacation on seven indicators. Participants' health and well-being improved during vacation on five indicators: health status, mood, tension, energy level and satisfaction. However, during the first week of work resumption, health and well-being had generally returned to pre-vacation levels. In conclusion, a winter sports vacation is associated with improvements in self-reported health and well-being among working individuals. However, these effects fade out rapidly after work resumption. We propose a framework for future vacation research and suggest investigating the role of vacation type, duration and means to prolong vacation relief.     

The mediating role of frustration of psychological needs in the relationship between job insecurity and work-related well-being

Abstract

This study aims to test a new process underlying the negative relationship between job insecurity and work-related well-being. Specifically, based on Self-Determination Theory, frustration of the psychological needs for autonomy, belongingness and competence was expected to explain the associations between job insecurity and emotional exhaustion and vigour (i.e. the core energy-related components of burnout and work engagement, respectively). Structural equation modelling using data from a heterogeneous sample of 3185 Flemish employees confirmed that frustration of the three needs mediated the association between job insecurity and both outcomes. These results suggest that job insecurity is related to impaired work-related well-being, because it frustrates employees’ psychological needs. This study contributes to a rather small, but growing body of research on the theoretical explanations of the negative consequences of job insecurity for employees’ work-related well-being.     

Job resources and emotional exhaustion: The mediating role of learning opportunities

The Job Demands-Resources model predicts that job demands increase and job resources decrease emotional exhaustion in employees. In this study, we investigated one possible mechanism for this, in order to provide a deeper insight into the role of job resources in this energy-depletion process. We assumed that job resources (autonomy and task variety) reduce emotional exhaustion through the promotion of opportunities for personal growth and development, especially workplace learning. Moreover, we expected that job demands (workload, cognitive and emotional demands) would be positively related to work-related learning opportunities. Our research model was tested in a large and heterogeneous sample out of the Dutch working population (N = 4589), following a cross-validation procedure. Multi-group structural equation modelling revealed that autonomy and task variety promoted learning opportunities, which in turn partially mediated between these job resources and emotional exhaustion. With respect to job demands, our study showed mixed results: cognitive demands promoted learning opportunities, workload frustrated such opportunities, and emotional demands were not significantly related to learning opportunities. Our results contribute to a better understanding of the interplay between job demands, job resources and learning opportunities in the energy-depletion process, and support the need for the promotion of learning opportunities in the workplace.     

The effects of transformational leadership on followers' perceived work characteristics and psychological well-being: A longitudinal study

Transformational leaders employ a visionary and creative style of leadership that inspires employees to broaden their interest in their work and to be innovative and creative. There is some evidence that transformational leadership style is linked to employee psychological well-being. However, it is not clear whether this is due to (1) a direct relationship between leadership behaviour and affective well-being outcomes, or (2) a relationship between leadership behaviour and well-being that is mediated by followers' perceived work characteristics. (Such characteristics include role clarity, meaningfulness, and opportunities for development.) This study aims to extend previous work by examining the validity of these two mechanisms in a longitudinal questionnaire study. The study was carried out within the elderly care sector in a Danish local governmental department. A theory-driven model of the relationships between leadership, work characteristics, and psychological well-being was tested using Structural Equation Modelling. The results indicated that followers' perceptions of their work characteristics did mediate the relationship between transformational leadership style and psychological well-being. However, there was only limited evidence of the existence of a direct path between leadership behaviour and employee well-being. These findings have implications for design, implementation, and management of efforts to improve employee well-being.     

The downside of organizational identification: Relations between identification,workaholism and well-being

Abstract

Employee organizational identification has been proposed and found to be positively related to employee health and well-being. The empirical evidence, however, is not unequivocal, and some authors have suggested possible downsides of identification with the organization as a whole or with a group within it. The potential negative effect of over-identification was tested empirically for the first time in the present paper. Two studies were conducted; Study 1 was cross-sectional and used a sample of Italian law court clerks (N=195) and Study 2 was longitudinal and employed a sample of Italian teachers (N=140 at T2). We proposed a curvilinear mediation model with identification curvilinearly predicting workaholism, and workaholism, in turn, negatively affecting employee well-being. This curvilinear link between organizational identification and workaholism means that workaholism at first decreases with growing identification, but when identification becomes too strong, workaholism increases. The results confirmed our hypotheses, and we discuss theoretical and practical implications.     

Warr's scale of job-related affective well-being: A longitudinal examination of its structure and relationships with work characteristics

The aims of this 3-year follow-up study among Finnish managers (n=615) were first, to test the theoretically-based structure of the job-related affective well-being scale (Warr, 1990b), and second, to examine the linear and curvilinear longitudinal associations between work characteristics and job-related affective well-being. Confirmatory factor analysis showed that the hypothesized four-factor model best described the structure of the job-related affective well-being scale; that is, the scale included four interrelated factors of job-related anxiety, comfort, depression, and enthusiasm at both measurement times. Structural equation modelling showed that high feelings of comfort at work were longitudinally associated with a positive perception of the supportiveness of the organizational climate, after controlling for sense of coherence. Conversely, the work characteristics included in this study (job control and supportive organizational climate) did not serve as antecedents of job-related affective well-being during the follow-up. In addition, there were no cross-sectional or longitudinal curvilinear associations between work characteristics and job-related affective well-being: associations were found to be linear. We conclude that (a) Warr's scale of job-related affective well-being is best conceptualized as consisting of four interrelated dimensions whose factor structure is (b) highly stable across a 3-year time interval.     

Transformational leadership and optimal functioning at work: On the mediating role of employees' perceived job characteristics and motivation

This study aimed to deepen our understanding of the motivational mechanisms involved in the relationship between transformational leadership (TFL) and employee functioning. Drawing on the TFL literature, the job demands–resources model and self-determination theory, we propose an integrative model that relates TFL to employee psychological health (burnout and psychological distress), attitudes (occupational commitment and turnover intention) and performance (professional efficacy, self-reported individual and objective organizational performance) through two explanatory mechanisms: perceived job characteristics (job demands and resources) and employee motivation (autonomous and controlled). This research was conducted in two occupational settings (nurses and school principals), using a distinct variable operationalization for each. Results of both studies provide support for the hypothesized model, suggesting that TFL relates to optimal job functioning (psychological health, job attitudes and performance) by contributing to favourable perceptions of job characteristics (more resources and less demands) and high-quality work motivation (more autonomous motivation and less controlled motivation) in employees. Theoretical contributions and managerial implications as well as directions for future research are presented.     

Return to work among employees with mental health problems: Development and validation of a self-efficacy questionnaire

Abstract

Because of the costs to both the organization and the individual, it is important that employees who are sick-listed with mental health problems are facilitated in their return to work (RTW). In order to provide adequate interventions, it is necessary to obtain a better understanding of the RTW process of people with mental health problems. Work-related self-efficacy (SE) might play a key role within this process. This paper describes the development and validation of the return-to-work self-efficacy’ scale (RTW-SE) for employees with mental health problems. Three Dutch samples of sick-listed employees were used to validate the 11-item instrument (N=2214). Based on the factor structure and reliability results, RTW-SE was conceptualized as a unitary construct. The associations with general SE, locus of control, coping, physical workload and mental health problems support the construct validity of this scale. Most importantly, RTW-SE proved to be a robust predictor of actual return to work within three months. The encouraging preliminary psychometric properties of the scale make it a potentially valuable tool in research and in clinical practice and occupational health care settings, both before and after employees have returned to work.     

Interruptions to workflow: Their relationship with irritation and satisfaction with performance,and the mediating roles of time pressure and mental demands

Understanding the mechanisms of workflow interruptions is crucial for reducing employee strain and maintaining performance. This study investigates how interruptions affect perceptions of performance and irritation by employing a within-person approach. Such interruptions refer to intruding secondary tasks, such as requests for assistance, which occur within the primary task. Based on empirical evidence and action theory, it is proposed that the occurrence of interruptions is negatively related to satisfaction with one's own performance and positively related to forgetting of intentions and the experience of irritation. Mental demands and time pressure are proposed as mediators. Data were gathered from 133 nurses in German hospitals by means of a five-day diary study (four measurements taken daily; three during a morning work shift and one after work, in the evening). Multilevel analyses showed that workflow interruptions had detrimental effects on satisfaction with one's own performance, the forgetting of intentions, and irritation. The mediation effects of mental demands and time pressure were supported for irritation and (partially) supported for satisfaction with performance. They were not supported for the forgetting of intentions. These findings demonstrate the importance of reducing the time and mental demands associated with interruptions.     

The association between blood pressure and work stress: The importance of measuring isolated systolic hypertension

The objective was to study whether the relationships between elevated blood pressure and (a) work stress as related to the stressor overtime, and (b) unwinding after work, depend on what kind of criteria are used for the diagnosis of hypertension. A total of 126 healthy men (aged 20-66 years) employed in white-collar jobs were tested over 24 hours by means of ambulatory blood pressure monitoring on a regular working day. Four groups were defined according to their blood pressure status: normotensives (NT), hypertensives (HT), isolated systolic hypertensives (ISH), and isolated diastolic hypertensives (IDH). No differences of age, body mass index, overtime work, and disturbed unwinding were found between the normotensives and the hypertensives. ISH was found to be related to working overtime and to disturbed unwinding but not to biological risk factors; IDH, however, was related exclusively to the biological risk factor high body mass index. Thus, significant differences associated with overtime were found between ISH and both NT and IDH, with the isolated systolic hypertensives carrying out more than twice as much overtime as the normotensives or isolated diastolic hypertensives. More men with a disturbed ability to relax and vital exhaustion were found in the ISH group than in the NT group. It seems that, in addition to the usual diagnosis of hypertension, the classification of ISH and IDH adds new information about the relationship between blood pressure elevation and both work stress and disturbed unwinding.     

The Job Demands-Resources Model in emergency service volunteers: Examining the mediating roles of exhaustion,work engagement and organizational connectedness

Using a sample of 887 volunteer emergency service workers in South Australia, we conducted a study based on the JD-R framework to examine the roles of three mediators in the relationship between job characteristics and volunteer well-being. These were (i) exhaustion as a mediator in the relationships between job demands and both poor mental health and turnover intentions; and (ii) work engagement and organizational connectedness as mediators in the relationships of job resources (training and organizational support) with happiness and turnover intentions. Organizational connectedness, a relatively new construct, is a positive state of well-being that involves an emotional connection with other workers, with service recipients and with aspects of the task and the organization's values. Results indicated that all three mediators were important in explaining volunteer well-being. Specifically, job demands were positively related to exhaustion, which, in turn, was linked to ill-health and turnover intentions. Job resources were positively related to work engagement and organizational connectedness, which were, in turn, negatively related to turnover intentions. However, while organizational connectedness mediated the relationship between job resources and happiness, this was not the case for work engagement. The roles of these variables in future research in paid and voluntary work are discussed.     

Beyond demand and control: The contribution of organizational risk factors in assessing the psychological well-being of health care employees

Abstract

The job demand–control(–support) model is frequently used as a theoretical framework in studies on determinants of psychological well-being. Consequently, these studies are confined to the impact of job characteristics on worker outcomes. In the present study the relation between work conditions and outcomes (job satisfaction, emotional exhaustion, psychological distress, and somatic complaints) is examined from a broader organizational perspective. This paper reports on an analysis that examines both the unique and the additional contribution of organizational characteristics to well-being indicators, beyond those attributed to job characteristics. A total of 706 care staff from three public residential institutions for people with mental or physical disabilities in the Netherlands took part in this research. To assess organizational risk factors a measurement instrument was developed, the organizational Risk Factors Questionnaire (ORFQ), based on the safety-critical factors of the Tripod accident causation model. Factor analyses and reliability testing resulted in a 52-item scale consisting of six reliable sub-scales: staffing resources, communication, social hindrance, training opportunities, job skills, and material resources. These organizational risk factors explained important parts of the variance in each of the outcome measures, beyond that accounted for by demographic variables and job demand–control–support (JDCS) measures. Communication and training opportunities were of central importance to carers’ job satisfaction. Social hindrance, job skills, and material resources explained a substantial amount of unique variance on the negative outcomes investigated.     

Overcoming the dark side of task conflict: Buffering roles of transformational leadership,tenacity, and passion for work

Drawing from the job demands–resources model, this study considers how task conflict reduces employees' job satisfaction, as well as how the negative task conflict–job satisfaction relationship might be buffered by supervisors' transformational leadership and employees' personal resources. Using data from a large organization, the authors show that task conflict reduces job satisfaction, but this effect is weaker at higher levels of transformational leadership, tenacity, and passion for work. The buffering roles of the two personal resources (tenacity and passion for work) are particularly salient when transformational leadership is low. These findings indicate that organizations marked by task-related clashes can counter the accompanying stress by developing adequate leadership and employee resources within their ranks.     

Measuring exposure to bullying at work: The validity and advantages of the latent class cluster approach

Abstract

This paper addresses the construct and predictive validity of two methods for classifying respondents as victims of workplace bullying. Although bullying is conceived as a complex phenomenon, the dominant method used in bullying surveys, the operational classification method, only distinguishes two groups: victims versus non-victims. Hence, the complex nature of workplace bullying may not be accounted for. Therefore a latent class cluster approach is suggested to model the data, which was obtained by using the Negative Acts Questionnaire (NAQ) administered to employees in Belgium (n=6,175). Latent class modelling is a method of analysis that does not appear to have been used in occupational health psychology before. In this study, six latent classes emerged: “not bullied,” “limited work criticism,” “limited negative encounters,” “sometimes bullied,” “work related bullied,” and “victims.” The results show that compared to the traditional operational classification method, the latent class cluster approach shows higher construct and higher predictive validity with respect to self-assessments and indicators of strain and well-being at work. The consequences of these results for theory, future research, and practice are discussed.     

Job demands and work-related psychological responses among Malaysian technical workers: The moderating effects of self-efficacy

Abstract

Job design has long been found to affect the work-related psychological responses of employees, such as psychological strain, job satisfaction, and turnover intentions, but scholars have begun to question whether established theoretical relations regarding job design continue to hold given the enormous changes in the nature of work during the past two decades. It is also increasingly recognized that individual differences affect work behaviours in substantial ways, but few studies on work design have investigated these differences. We addressed these concerns with a two-wave longitudinal study among 245 technical workers at a telecommunications company in Malaysia, a country that has a collectivist culture and a high power distance between managers and subordinates. We examined the moderating effects of job control and self-efficacy on the relationships between job demands and employee responses. The results failed to support the job demands-control model, as job control variables did not moderate the impact of demands on employee work-related psychological responses. However, self-efficacy moderated their impact on psychological strain (although not on job satisfaction or turnover intentions). Our findings provide insight into the moderating effect of self-efficacy, and suggest that practitioners interested in reducing psychological strain should consider making efforts to increase self-efficacy among employees.
