Moderating effects of social support in shiftworking and non-shiftworking nurses

In this study the causal relationships between work characteristics, in terms of job demands and job resources, and both targets’ and perpetrators' reports of workplace bullying, are investigated. In line with the Job Demands-Resources model and the bullying literature, we assumed that both high job demands (i.e. workload, role conflict and job insecurity) and low job resources (i.e. task autonomy, social support and skill utilization) increase bullying over time (i.e. normal causation). Our sample included 177 employees of various establishments of a large Belgian organization. The results of structural equation modelling analyses partially supported our hypothesis. As expected, we found that T1 job demands related positively to targets’ reports of bullying at T2 one year later, and that T1 job resources related negatively to T2 targets’ reports of bullying. Unexpectedly, there was no significant cross-lagged effect of T1 job demands and resources on T2 perpetrator's reports of bullying. No evidence was found for reverse causation or reciprocal effects. Overall, at least for targets, these findings support the validity of the theoretical models postulating a causal link from work characteristics to workplace bullying.     

Long-term profiles of work-related rumination associated with leadership,job demands,and exhaustion: A three-wave study

This study extends previous research on recovery from work stress by investigating the role of qualitative job demands and leadership in employees’ work-related rumination (WRR). The long-term development of WRR was examined from a person-centred approach across 22 months. Drawing on the stressor-detachment framework and conservation of resources theory, we investigated whether different WRR profiles could be understood in terms of levels of and changes in quantitative, cognitive, and emotional job demands, several aspects of supervisory leadership, and exhaustion that was expected to result from the impeded energy restoration process. A three-wave questionnaire study was conducted among Finnish municipal employees in heterogeneous occupations. Factor mixture modelling was used to identify latent classes (i.e. subgroups of participants with similar mean levels and mean-level changes) of WRR. The results indicated five distinct classes of WRR. Participants in the higher WRR classes reported higher levels of job demands, less supervisor fairness, and more abusive supervision. In the decreasing class, WRR decreased concurrently with decreasing job demands. Exhaustion showed considerable congruence with WRR both between and within persons. The findings are discussed from the point of view of a loss cycle concerning energetic psychological resources and difficulties in goal attainment.     

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.     

Exploring work- and organization-based resources as moderators between work-family conflict, well-being, and job attitudes

In modern Western life it is difficult to avoid work-family conflict. Therefore the resources that might reduce its negative outcomes on well-being and job attitudes come into focus. Our study contributes to the work-family conflict literature by exploring the indirect (moderator) and direct role of three work- and organization-related resources, i.e., job control, family supportive climate, organization-based self-esteem (OBSE), in the work-to-family conflict and well-being/job attitude relationship. Theoretically, the study tested the recently developed Job Demands-Resources (JD-R) model in the Scandinavian context. Data for the study were gathered from three differing Finnish organizations (health care district, ICT company, Cardboard mill; n=1252). In line with the predictions of the JD-R model, job demands (time- and strain-based work-to-family conflict) were more robustly associated with strain-based outcomes (physical symptoms), whereas job resources (job control, family supportive climate, OBSE) were more strongly linked to motivational-based outcomes (job satisfaction, organizational commitment). Both job control and family supportive climate moderated the relationships studied; high job control and family supportive climate buffered against the aversive effects of work-to-family conflict on well-being and job attitudes. These indirect effects also varied in relation to the independent, moderator, and dependent variables. However, OBSE did not operate as a buffering factor, although it showed significant direct effects. From a practical viewpoint, our findings suggest that job control and family supportive climate are resources that help employees to reduce the negative effects related to work-family conflict.     

Testing the Vitamin Model of job stress in Dutch health care workers

Three central hypotheses of Warr's Vitamin Model concerning the relationship between job characteristics and well-being and health outcomes were tested: (1) differential effects of job characteristics on the various well-being and health outcomes; (2) predominance of curvilinear associations; and (3) moderate influence of negative and positive affectivity on these relationships. The study participants were 162 employees from a health care organization (aged 19-54 years, 95% women) who completed questionnaires on job demands and job autonomy, as well as on the outcome variables depression, anxiety, job satisfaction, and health complaints. In addition, data on short-term sickness absence were collected. A higher level of job demands was significantly associated with a lower level of well-being and self-reported health. Job autonomy showed weaker relationships with the outcome variables. The effects of job demands were still large after controlling for negative and positive affectivity, while the effects of job autonomy in most cases became non-significant. The predicted curvilinear relationship between job characteristics and outcome variables did not have an additional value over a linear model in predicting the data. It is concluded that the present data from a homogeneous sample of mostly female nurses support Warr's Vitamin Model to a limited extent.     

Cardiac measures of stress in British prison officers

Abstract

Previous research has found that alternative employment arrangements are associated with both impaired and improved well-being. Since such inconsistencies are likely to derive from the type of employment contract as well as the characteristics of the job, this paper compares permanent full-time work with forms of alternative employment (permanent part-time, fixed-term and on-call work) in order to investigate how different employment contracts and perceptions of job conditions relate to individual well-being. This study contributes to the literature by addressing several questions. Different forms of alternative employment are distinguished and individual background characteristics that might be intertwined with the employment contract are controlled for. Moreover, the scope of this study extends to the effects of perceived job conditions, and possible interactive effects with type of employment are tested. Analyses of questionnaire data from 954 Swedish healthcare workers show that perceptions of the job (job insecurity, job control and demands), but not the type of employment contract, predicted health complaints. However, type of employment interacted with perceptions of job insecurity, in that insecurity was associated with impaired well-being among permanent full-time workers, while no relationship was found for on-call or core part-time employees. Despite the absence of interactions between employment contract and job demands or job control, it can be concluded that knowledge about the relationship between alternative employment arrangements and the well-being of workers can be enhanced when the combined effects of employment contract and job conditions are studied.     

The importance of context specificity in work stress research: A test of the Demand-Control-Support model in academics

The Demand-Control (D-C) (Karasek, 1979) and the Demand-Control-Support (D-C-S) (Johnson & Hall, 1988; Johnson, Hall, & Theorell, 1989; Karasek & Theorell, 1990) models of work stress suggest that jobs with high demands and low control (and low support) are stressful. In line with the support in the literature for context-specificity in occupational stress research (Sparks & Cooper, 1999) and the limited and even contradictory support for interaction effects, the main aim of the present study was to examine how the D-C-S model applied in a well-defined occupational group. Using hierarchical regression analyses, and controlling for negative affect, the D-C-S model accounted for 26%, 6%, and 8% of the variance in job satisfaction, psychological distress and burnout, respectively, among 166 academics in a UK university. No two-way or three-way interactive effects were evident, but additive effects of job demands and control on psychological well-being and of job demands and support on both burnout and job satisfaction were shown, corroborating research showing that high job strain is linked to ill health and job dissatisfaction in this homogenous occupational sample. It is recommended that, in future, research includes more variables that are specific to a particular occupation.

Learning new behaviour patterns: a longitudinal test of Karasek's active learning hypothesis among Dutch teachers

This investigation deals with the active learning hypothesis in Karasek and Theorell's (1990) job demands-control model. The active learning hypothesis holds that high levels of learning and self-efficacy will occur among incumbents of high job demands/high job control jobs, whereas low levels of learning and self-efficacy will be found in low demands/low control jobs. This study tested these notions in the context of a two-wave study conducted over a period of one year among 876 Dutch teachers. Regression analysis revealed that job demands had a lagged negative (rather than a positive) effect on learning and self-efficacy; as expected, job control had a positive effect. Thus, the highest levels of learning and self-efficacy were found among incumbents of high control/low demands jobs (and not among incumbents of high control/high demands jobs). Further, the effects of changes in work characteristics on changes in learning behaviour and self-efficacy were examined, providing additional evidence that especially the transition from a low demands/low control to a high demands/low control job is associated with a strong deterioration of learning and self-efficacy. It is concluded that future research should address the interrelationships between learning and strain, preferably using longitudinal designs.     

The New Zealand government approach to stress and fatigue

Abstract

Self-control involves inhibiting undesired behaviours and emotions, and it can be particularly relevant in the service sectors. Recent theoretical developments in cognitive and social psychology suggest that the demands on an individual of exercising self-control have an effect as a source of stress at work. In turn, burnout could be associated with being unable to meet those demands. It was expected that cognitive control deficits, as assessed by a questionnaire measure of self-reported failures in perception, memory, and action, would function as a vulnerability factor in the relationship between self-control demands and indicators of job strain. Data from 630 staff members of a German municipal administration revealed significant main effects of both self-control demands and cognitive control deficits on the burnout dimensions of emotional exhaustion and depersonalization. Both predictors were positively related to burnout. In addition, the results provided clear evidence of the vulnerability hypothesis of cognitive control deficits. By way of contrast, musculoskeletal complaints did not reflect similar main and interactive effects of self-control demands and cognitive control deficits. The requirements for self control in the service sector are expected to increase as the sector expands, and the practical implications for this are discussed.     

Is it worth it? Linking perceived high-performance work systems and emotional exhaustion: The mediating role of job demands and job resources

The present study utilizes the job demands–resources model and examines the effects of employees’ perceptions of high-performance work systems (HPWS) on emotional exhaustion. For the needs of this study, structural equation modeling (SEM) was used on a sample of 343 frontline employees in a Greek manufacturing company. The findings do not support the critical arguments regarding HPWS, which suggest that these systems lead to work intensification and emotional exhaustion through increased job demands. In contrast, HPWS was positively related to job resources, although no support was found for a direct and negative relationship with emotional exhaustion. Last but not least, this study calculates HPWS as both a system and bundles of practices and provides useful insights regarding the differences between the two different measurement methods. Finally, theoretical and managerial implications are drawn for improving our understanding of how HPWS influences job demands and resources and employees’ emotional exhaustion.     

Control, stress, and job satisfaction in Canadian nurses

The main effects of four domains of control (task, decision, resource, physical environment) on job satisfaction and their interactions with three types of job stressors (task demands, role conflict, interpersonal conflict) were examined in a sample of 765 Canadian nurses. Multiple regression analyses were conducted to determine the proportion of variance in job satisfaction that could be accounted for by job stressors, control, and the interaction of stressors and control in that order. The job stressors were analysed separately and as a composite job demands score, as were the four domains of control. The results indicated that the proportion of variance in job satisfaction increased with the addition of control for the composite scores and for task, resource, and physical environment control. However, decision control did not account for additional variance in job satisfaction above that for any of the job stressors. In addition, none of the stressor x control interactions were significant. The results support previous attempts to test the moderating effects of control, suggesting that perceived control is not a moderator of job stress but rather that it has a direct influence. The relevance of the different domains of control for nurses is discussed.     

Back to basics: Re-examination of Demand-Control Theory of occupational stress

The Demand-Control model of occupational stress posits an interaction between job demands and job control predicting psychological strain, but previous research has found such an interaction only rarely or inconsistently. Such research, however, has often failed to measure either demands or strain faithfully to the model's constructs, or has simply failed to test for a statistical interaction. The present study corrected these shortcomings by going back to basics. Using a sample of 115 employees in a manufacturing company, it operationalized the variables more consistently with their original conceptualizations. However, when the hypothesized Demand-Control interaction was then tested, it still failed. Outcomes other than psychological strain (e.g. job dissatisfaction) were related negatively rather than positively to demands. This highlights the difference between psychological strain and dissatisfaction and casts doubt on models positing dissatisfaction as an intervening variable between stressors and strains.     

Occupational stress in universities: staff perceptions of the causes, consequences and moderators of stress

In recent years, the Australian university sector has undergone large-scale organizational change, including restructuring, downsizing and government funding cuts. At the same time, research from across the globe reports an alarming increase in the occupational stress experienced by university staff. We report on the first phase of a longitudinal investigation of occupational stress. A total of 22 focus groups were conducted with a representative sample of 178 academic and general staff from 15 Australian universities. The groups focused on understanding staff 's experience of occupational stress, and perceptions of the sources, consequences and moderators of stress. Both general and academic staff reported a dramatic increase in stress during the previous 5 years. As a group, academic staff reported higher levels of stress than general staff. Five major sources of stress were identified including: insufficient funding and resources; work overload; poor management practice; job insecurity; and insufficient recognition and reward. The majority of groups reported that job-related stress was having a deleterious impact on their professional work and personal welfare. Aspects of the work environment (support from co-workers and management, recognition and achievement, high morale, flexible working conditions), and personal coping strategies (stress management techniques, work/ non-work balance, tight role boundaries and lowering standards), were reported to help staff cope with stress. The findings provide a timely insight into the experience of stress within universities.     

Job crafting and well-being among school principals: The role of basic psychological need satisfaction and frustration

This study investigates the associations between school principals’ job crafting and well-being. Drawing on the job demands-resources approach of the job crafting model and self-determination theory, we hypothesized that need satisfaction and need frustration act as likely mechanisms between the positive and negative effects of job crafting behaviors and work-related well-being (work engagement and burnout). Using cross-sectional data collected from a sample of Finnish school principals (n = 518), our structural equation model revealed that crafting structural job resources was positively associated with need satisfaction and negatively with need frustration. Increasing challenge job demands was positively associated with need satisfaction, which, in turn, was associated with higher work-related well-being. In addition, crafting structural job resources was directly positively linked to burnout as well as work engagement. Moreover, we found that decreasing hindrance demands was positively associated with burnout and negatively associated with work engagement via need frustration. No associations were found between crafting social resources, indicators of basic psychological needs, or work-related well-being. These findings provide insights into how principals determine their own basic psychological needs via job crafting, and how this is reflected in their work-related well-being. The study advances job crafting theory and self-determination theory, with important implications for practice and future research.     

Exploring work- and organization-based resources as moderators between work–family conflict,well-being,and job attitudes

The impact of a participatory organizational intervention on job stress in community health care institutions

The aim of the present study was to investigate the effect of a short-term participatory intervention in health care institutions in Norway on workers' control, other job characteristics, job stress, subjective health and job satisfaction. Participants (including managers and supervisors) were randomly allocated to intervention groups and to a control group. Actions to solve problems based on the employees' own perceptions of the main problems were seen as the key motivators for organizational improvement and increased control at the task and office level in the work situation. The main stressors identified by the participants in this study were lack of information, communication and respect between professions, as well as the need for professional and personal development. The participatory intervention had a positive, but limited effect on work-related stress, job characteristics, learning climate and management style, and seemed to have started a beneficial change process. There were no negative short-term effects on work-related stress and job demands. Organizational interventions may be a potential training ground for acquiring participatory skills and resources, and if sustained after the intervention period, they can have long-term effects on problem solving, job stress and employee satisfaction.     

The development and validation of a job crafting measure for use with blue-collar workers

Abstract

Job crafting describes a set of proactive behaviours in which employees may engage to shape their work in order to minimize hindering job demands and maximize resources and challenging demands. Such behaviours may be particularly important among blue-collar workers whose jobs are characterized by poor working conditions and low well-being. We present the development and adaptation of a job crafting measure that may be used among blue-collar workers, based on an existing scale by Tims, Bakker, and Derks (2012) that was not specifically developed for blue-collar workers. We test the validity and reliability of the measure in a longitudinal study based on multiple source information from mail delivery workers in Denmark (N=362 at Time 1; N=408 at Time 2). Results indicate the presence of five job crafting dimensions: increasing challenging demands, decreasing social job demands, increasing social job resources, increasing quantitative demands and decreasing hindering job demands. These can be reliably measured with 15 items. The measure shows acceptable discriminant and criterion validity, and test-retest reliability. The findings extend the application of the original questionnaire. They also add to knowledge of the job crafting behaviours in which blue-collar workers engage and link them to well-being outcomes.
