The relationships between work characteristics and mental health: examining normal,reversed and reciprocal relationships in a 4-wave study

This longitudinal study examined the causal relationships between job demands, job control and supervisor support on the one hand and mental health on the other. Whereas we assumed that work characteristics affect mental health, we also examined reversed causal relationships (mental health influences work characteristics). Further, the topic of the appropriate time lag for testing causal relationships was addressed. Our hypotheses were tested in a 4-wave study among a heterogeneous sample of 668 Dutch employees using structural equation modelling. The results provide evidence for reciprocal causal relationships between the work characteristics and mental health, although the effects of work characteristics on well-being were causally predominant. The best model fit was found for a 1-year time lag. Compared to earlier—predominantly cross-sectional—results, the present study presents a stronger case for the effects of work characteristics on the development of strain. The results also emphasize the need for a dynamic view of the relationship between work and health; the one-directional viewpoint in many work stress models does not seem to fully capture the relations between work characteristics and well-being.

The moderating role of social support in Karasek's job strain model

This paper examines whether social support is a boundary-determining criterion in the job strain model of Karasek (1979). The particular focus is the extent to which different sources of social support, work overload and task control influence job satisfaction, depersonalization and supervisor assessments of work performance. Hypotheses are tested using prospective survey data from 80 clerical staff in a university setting. Results revealed 3-way interactions among levels of support (supervisor, co-worker, non-work), perceived task control and work overload on levels of work performance and employee adjustment (self-report). After controlling for levels of negative affect in all analyses, there was evidence that high levels of supervisor support mitigated against the negative effects of high strain jobs on levels of job satisfaction and reduced reported levels of depersonalization. Moreover, high levels of non-work support and co-worker support also mitigated against the negative effects of high strain jobs on levels of work performance. The results are discussed in terms of the importance of social support networks both at, and beyond, the work context.     

Longitudinal influences of managerial support on employee well-being

A three-wave longitudinal survey of managers working for a food retailer (n = 148) assessed both job characteristics and individual well-being during a period of organizational restructuring. Repeated measures analysis of variance revealed significant changes in both job characteristics and well-being across the three surveys. In addition, longitudinal structural equation models were developed to model the relationships between job characteristics and two indices of strain (job satisfaction and mental health) over time, including the assessment of the relative fit of competing causal process models. After controlling for the temporal stability of all variables, both types of strain were predicted by a combination of prior strain, prior job characteristics and current job characteristics. More specifically, managerial support was found to influence job satisfaction both directly and through perceptions of role ambiguity and control. Mental health was consistently predicted by low current and prior work demands, and in addition was associated with high managerial support. These results suggest that interventions to enhance employee well-being might usefully focus on increasing managerial support. Recommendations for research intending to examine the direction of causal associations between job characteristics and strain are made.     

Workplace Change and Employee Mental Health: Results from a Longitudinal Study

This study is intended to improve understanding of the impact of workplace change on employee mental health and well‐being. We construct and test a comprehensive measure of organizational change, which is then applied in a prospective longitudinal study of nearly 5400 employees in six UK National Health Service Trusts. Self‐rated mental health was assessed using the 12‐item version of the General Health Questionnaire (GHQ). Just under a quarter of the sample were at increased risk of psychiatric morbidity (‘cases’). After controlling for a wide range of personal characteristics and work variables, it was found that respondents who reported an increase in the amount of work over the previous year were more likely to be classed as GHQ cases, whereas increased training and promotion and improved job security had a beneficial effect on employee mental health (less likelihood of being GHQ cases). Quantity or degree of change showed a somewhat ambiguous relationship with GHQ status. Our findings challenge the assumption that change will necessarily have an adverse effect on health, indicating areas, such as promotion and development, where a positive impact might be anticipated.     

A longitudinal study exploring the relationships between occupational stressors, non-work stressors, and work performance

There is a lack of intricate research into the relationships between work performance and other variables. This study examined the causal relationship between work, non-work stressors, and work performance. Using longitudinal multi-group data from three groups—university staff, trainee nurses, and part-time employees (overall N=244)—structural equation modelling was employed to explore one-way and reverse competing models. The results produced a good fitting model with one-way causal paths from work-related and non-work stressors (time 1) to job performance (time 2). Nested model comparison analysis provided further evidence to support this best fitting model, emphasizing the strong influence that non-work factors have within the workplace. This study has important implications for theory, methodology and statistical analysis, and practice in the field of work-related stressors and performance.

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.     

Job design and levels of physical and mental strain among Australian prison officers

Over the past 15 years much has been made of the moderating influence of job discretion and support in occupations that are perceived to be high in demands. Such an effect seems to be most prevalent when subject populations are large and heterogeneous. One aim of this study was to examine the influence of subjective perceptions of these variables on strain reactions among a group of relatively homogeneous workers such as, in the present study, prison officers (n = 274). A second aim was to extend previous research and examine the joint influence of negative affectivity and perceptions of demands, discretion, and support on mental and physical well-being. It was hypothesized that those high in negative affect would be particularly strained by jobs perceived as being demanding. The hypothesized relationship between job demands, discretion and support were found to be weak and at times inconsistent. Social support, in particular, was found to have both positive and negative consequences for different aspects of well-being. Those high in negative affect were in general found to suffer lower mental well-being. More importantly, the interactive effect of negative affectivity and job demands was found to significantly predict the majority of the dependent variables used in this study. The valences of these relationships were inconsistent and are interpreted in light of Warr's (1987) vitamin model of stress.

There are several conclusions that can be drawn from the present study. Negative affectivity appears to have a truly interactive effect with job components, job demands in particular, to influence a range of variables relating to physical and mental health as well a job-related attitudes. The nature of these effects, however, suggests a dissociation in the ways that different independent variables influence a range of indices of well-being and affect. This result requires further investigation since there are important theoretical implications which will follow if the data are replicable.

In order to examine such complex effects, in addition to the need for more longitudinal studies, it is also important that standardized measures of job components are developed so that levels of stress exposure can be equated and their impact assessed across organizational settings.

Finally, the data reported in this study suggest that some effective stress management may be undertaken by adopting selection strategies which take into consideration individual characteristics. In view of the fact that individual stress management programmes are of unproven benefit (Murphy 1986, 1988) such an approach is recommended especially for those organizations which are highly constrained in the services that must be performed.     

Expatriate adjustment and effectiveness: The mediating role of managerial practices

The purpose of this study was to examine the mediating effects of relations-oriented managerial behaviors on the relationship between two modes of expatriate adjustment—role innovation and personal change—and contextual performance. Using data from 194 expatriates and 505 of their subordinates, we found evidence of full mediation for the role innovation–performance relationship. For ratings of expatriate effectiveness, recognizing and team building behaviors appear to fully mediate the role innovation–performance relationship. For ratings of supervisor satisfaction, inspiring, supporting, and team building appear to fully mediate the role innovation–performance relationship. No significant results were found for the personal change–performance relationship. The results provide insights for extending current models of the expatriate adjustment process, and understanding the means by which expatriates fulfill their responsibilities.

Work-self balance: A longitudinal study on the effects of job demands and resources on personal functioning in Japanese working parents

Abstract

In work-family research the effects on the individual, or the “self”, in terms of personal interests independent of the work and family domains, have been largely neglected. This longitudinal study on 471 Japanese employees with young children investigated how job demands and job resources may have an impact on well-being by facilitating or hindering personal functioning. It was hypothesized that workload would have an unfavourable impact on work-to-self conflict, while supervisor support would have a favourable impact on work-to-self facilitation. In addition, we hypothesized that work–self conflict would diminish well-being (psychological distress and happiness), while work–self facilitation would enhance well-being over time. Structural equation modelling analyses using a full panel design showed that work overload was positively related to work–self conflict over time, whereas supervisor support was positively related to work–self facilitation. Furthermore, work–self conflict predicted psychological distress and happiness at T2, one year later, after controlling for T1 levels. These findings suggest that the demands and resources encountered at work can spill over to the home domain and have an impact on personal functioning and context-free well-being. Further research is needed to determine the importance of work-self constructs in relation to work-family constructs.     

Job stress, satisfaction and mental health of factory workers in Bangladesh

The present study examined the relationship between job stress, job satisfaction and mental health, and attempted to assess the effects of job stress on different parameters of satisfaction and mental health in the context of two groups of Bangladeshi factory workers. There were 26 subjects in a 'high stress' group and 33 in a 'low stress' group. Individual data were collected by using the Stress and Arousal Checklist, the Job Satisfaction Scale, the General Health Questionnaire, absenteeism by sick leave, a self-esteem at work scale and heart rate monitor. Chi-square and t-tests were applied in the analyses of these data by group. The results, quite expectedly, showed that a greater number of high stress subjects were dissatisfied and had poorer mental health than low stress subjects. The results also showed that low stress subjects were significantly more satisfied and possessed better mental health than the high stress subjects. It would appear that the experience of stress plays an important role in determining the quality of working life of Bangladeshi factory workers having similar consequences in terms of health and well-being to those observed in developed countries. The dynamics of absenteeism in Bangladesh are discussed.     

The physical activity-mediated Demand–Control (pamDC) model: Linking work characteristics,leisure time physical activity,and well-being

Only recently has research begun to investigate the interplay between work characteristics, leisure time physical activity (LTPA), health, and well-being. So far, however, this research lacks a theoretical foundation. In this article, we introduce the physical activity-mediated Demand–Control (pamDC) model as a new theoretical framework. The two key ideas of the pamDC model are (1) that job demands and job control affect LTPA and (2) that LTPA partially mediates the effects of job demands and job control on health and well-being. We present eight propositions explaining how work characteristics affect LTPA, health, and well-being. For each of these propositions, we discuss empirical evidence and theoretical foundations. We then sketch a research agenda on how to adopt the pamDC model as a new theoretical framework for future research linking work characteristics, LTPA, and health. Finally, we discuss the practical implications of our new model.     

The relationship between perceived employability and subsequent health

Being capable of getting new employment may enable an employee to cope with turbulent situations or deteriorating job conditions. Individuals who have higher perceived employability are likely to appraise a situation at work more favourably, and consequently experience better health and well-being. The aim of the present study was to investigate the relationship between perceived employability and subsequent health, while controlling for baseline health, background factors, and work environment exposures. The study is based on 53 items in the National Working Life Cohort in Sweden from two data collections (2004 and 2005), comprising 1918 individuals. Forced entry hierarchical regression analysis showed that, after controlling for demographics, psychological demands, control, and ergonomic exposures, perceived employability was positively associated with global health and mental well-being, but unrelated to physical complaints. When baseline health status was added, perceived employability was still a significant predictor of two out of three outcome variables. Individuals with higher perceived employability had a tendency to report better health and well-being a year later. It is concluded that how an employee perceives his or her possibilities in regard to acquiring new employment is relevant for well-being at a later stage. Perceived employability, which has been little studied before, is therefore a useful concept in health promotion, both at the individual and at the organizational level.     

Reducing turnover intent: supervisor and co-worker incivility and socialization-related learning

Emerging leaders are involved in a continual learning process that includes professional and personal identities that intersect and diverge. The identities are coupled with multiple roles and expectations that are embedded within work and non-work identities. This paper examines the impact of leadership development programmes on emerging leaders including the expectations and job demands that are integral to leadership work. More specifically, the paper examines the discourse between work and non-work identities and the strategies of leaders and organizations to strengthen or modify those identities. Monthly Activity Reports prepared by leadership participants were examined and used to support the findings. Additionally, environmental factors that shape the leaders' thoughts and behaviours were examined as the leaders struggled to maintain their core beliefs and work practices in a quest to become leaders or loyalists.     

Job satisfaction and mental health of temporary agency workers in Europe: a systematic review and research agenda

ABSTRACT

The current systematic literature review aimed to analyse the associations between temporary agency work (TAW), job satisfaction, and mental health in Europe, as well as to outline a future research agenda. Twenty-eight scientific articles were identified by searching different data bases (i.e. PSYNDEX, PsycINFO, PubMed, and Web of Science) for the time span from January 2000 to December 2016. Our review reveals first that TAW is not consistently negatively related to job satisfaction. However, job insecurity and working conditions are important mediators in the relation of TAW and lowered job satisfaction. Second, TAW is not consistently related to all investigated types of mental health impairments. However, when focusing on specific outcomes and comparing temporary agency workers to permanent employees, we still find consistent evidence regarding higher levels of depression and fatigue among temporary agency workers. Inconsistent associations between TAW, job satisfaction and mental health can partly be attributed to unfavourable methodological aspects of the included primary studies. To address these aspects, future research should consider applying a standard measurement of TAW, including a minimum of meaningful confounding variables, improving the operationalisation of outcome variables and the study design.     

The relationship between perceived employability and subsequent health

Abstract

Being capable of getting new employment may enable an employee to cope with turbulent situations or deteriorating job conditions. Individuals who have higher perceived employability are likely to appraise a situation at work more favourably, and consequently experience better health and well-being. The aim of the present study was to investigate the relationship between perceived employability and subsequent health, while controlling for baseline health, background factors, and work environment exposures. The study is based on 53 items in the National Working Life Cohort in Sweden from two data collections (2004 and 2005), comprising 1918 individuals. Forced entry hierarchical regression analysis showed that, after controlling for demographics, psychological demands, control, and ergonomic exposures, perceived employability was positively associated with global health and mental well-being, but unrelated to physical complaints. When baseline health status was added, perceived employability was still a significant predictor of two out of three outcome variables. Individuals with higher perceived employability had a tendency to report better health and well-being a year later. It is concluded that how an employee perceives his or her possibilities in regard to acquiring new employment is relevant for well-being at a later stage. Perceived employability, which has been little studied before, is therefore a useful concept in health promotion, both at the individual and at the organizational level.     

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.     

Personality and organizational health: the role of conscientiousness

Organizational health research identifies processes through which the work environment and individual differences combine to influence both individual and organizational outcomes. This study investigated the contribution of conscientiousness to organizational health. Research in the areas of occupational stress, work performance, and organizational climate was used to develop a framework for integrating different elements of organizational health. Within this framework, the work environment was assessed by perceptions of workload and role clarity ; individual well-being was assessed by psychological distress and job satisfaction ; and behaviour important for organizational success was assessed by contextual performance. Conscientiousness was investigated within the framework using self-reports from a sample of 104 Australian employees. Conscientiousness directly influenced contextual performance but did not influence well-being or perceptions of the work environment. Conscientiousness also reduced the impact of role clarity on both psychological distress and job satisfaction. The role of conscientiousness in a comprehensive model of organizational health is discussed.
