Staying well and engaged when demands are high: The role of psychological detachment.

The authors of this study examined the relation between job demands and psychological detachment from work during off-job time (i.e., mentally switching off) with psychological well-being and work engagement. They hypothesized that high job demands and low levels of psychological detachment predict poor well-being and low work engagement. They proposed that psychological detachment buffers the negative impact of high job demands on well-being and work engagement. A longitudinal study (12-month time lag) with 309 human service employees showed that high job demands predicted emotional exhaustion, psychosomatic complaints, and low work engagement over time. Psychological detachment from work during off-job time predicted emotional exhaustion and buffered the relation between job demands and an increase in psychosomatic complaints and between job demands and a decrease in work engagement. The findings of this study suggest that psychological detachment from work during off-job time is an important factor that helps to protect employee well-being and work engagement.

Theories of job stress and the role of traditional values: A longitudinal study in China.

This study examines how traditionality influences the relationships between job stressors and health. A sample of 496 Chinese employees provided longitudinal questionnaire data, and their health was assessed by collecting blood samples and monitoring blood pressure. The results indicated that the positive relationship between job control and health was stronger among the less traditional workers, whereas the positive relationship between distributive justice and health was stronger among the more traditional workers. Furthermore, traditionality moderated the interactive effects of job demands and perceived control/justice on health. Perceiving higher control mitigated the effects of job demands on upper respiratory infections among low traditionalists, but it exacerbated the effects among the high traditionalists. Perceptions of higher justice mitigated the effects of job demands on emotional exhaustion and immunoglobulin A for high traditionalists but not for low traditionalists. These results suggest that, in the relationship between job demands and psychological and physiological health, concern for equity is an important moderator for individuals with more traditional values, whereas perceived personal control is salutary for health primarily among people with less traditional values.

Balancing Work and Home: How Job and Home Demands Are Related to Burnout.

The aim of the present study was to make a clear distinction between work and home domains in the explanation of burnout. First, a 3-factor structure of job and home demands was hypothesized, consisting of quantitative demands, emotional demands, and mental demands. Next, a model was tested that delineates how demands in both life domains are related to occupational burnout through work-home interference (WHI) and home-work interference (HWI). In doing so, the partial mediating role of WHI and HWI was examined. Consistent with hypotheses, empirical support was found for the 3-factor structure of both job and home demands as well as for the partial mediating effects of both WHI and HWI. Job demands and home demands appeared to have a direct and indirect effect (through WHI and HWI, respectively) on burnout. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of psychological hardiness, job demands, and job control on sickness absence: A prospective study.

This study prospectively investigated the effects of psychological hardiness, job control, and job demands on medically certified sickness absence. Data from a questionnaire survey were combined with archival data for sickness absence among 7,239 civilian and military employees of the Norwegian Armed Forces (84.3% male, 69.8% military). A 2-component hurdle regression was used in the statistical analyses of the sickness absence data. After controlling for age, sex, and baseline absence, hardiness predicted both the likelihood of having any sickness absence (odds ratio = 0.97) and the number of absence spells (a 6.5% decrease in the expected count for 1 standard deviation change in hardiness). In addition, an interaction was found among hardiness, job control, and psychological demands. When demands were high, high job control was associated with more absence among employees with low levels of hardiness. Together, these findings point to hardiness as an important individual resource in relation to health, and that it is necessary to consider individual differences when examining the effects of work characteristics.

Workplace bullying: The role of psychosocial work environment factors.

Utilizing reports from both observers and direct targets, the authors examined the role of psychosocial work environment factors in workplace bullying, focusing on the moderating effects of control and support resources against job demands. Our sample was 716 Australian frontline police officers who completed an anonymous mail survey. In a direct test of Job Demand-Control-Support theory, the authors found that increased levels of bullying (as assessed by targets and observers) were associated with potentially high stress situations: as job demands increased and as support and control resources decreased. Also, consistent with previous research, most perpetrators were ranked higher than the target, reflecting the role of power in facilitating bullying. Our research is unique in finding evidence for moderating factors within the psychosocial environment and suggests risk assessment of the work environment as an avenue for bullying prevention. Future research should examine more closely the mechanisms underlying bullying within stressful work environments and the reciprocal effect of witnessing and experiencing bullying on psychosocial working conditions.

Work and health outcomes among police officers: The mediating role of police cynicism and engagement.

This study examined the relationship between personality variables (Type A), job demands and job resources, and police cynicism and engagement, and also examined the mediating role of cynicism and work engagement in predicting both work and health related outcomes among police officers. The participants were 150 Norwegian police officers, and data were collected using questionnaires. Results showed that Type A behavior was related to both cynicism and engagement. As predicted, both job demands and lack of job resources were related to cynicism, and job resources were positively related to engagement. A series of regression analyses indicated direct relationships between Type A behavior, job demands and health complaints with no mediating effect of cynicism. Work engagement partially mediated the effects of individual characteristics, job demands and job resources on organizational commitment and self-efficacy. However, direct links between demands and resources and organizational commitment were also found, as well as direct links between Type A behavior, work demands and self-efficacy. The implications of work engagement for organizations were discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Job Resources Buffer the Impact of Job Demands on Burnout.

This study tested and refined the job demands-resources model, demonstrating that several job resources play a role in buffering the impact of several job demands on burnout. A total of 1,012 employees of a large institute for higher education participated in the study. Four demanding aspects of the job (e.g., work overload, emotional demands) and 4 job resources (e.g., autonomy, performance feedback) were used to test the central hypothesis that the interaction between (high) demands and (low) resources produces the highest levels of burnout (exhaustion, cynicism, reduced professional efficacy). The hypothesis was rejected for (reduced) professional efficacy but confirmed for exhaustion and cynicism regarding 18 out of 32 possible 2-way interactions (i.e., combinations of specific job demands and resources).

Work characteristics, learning-related outcomes, and strain: A test of competing direct effects, mediated, and moderated models.

Direct effect, mediated, and moderated models of the relationship among work characteristics (job control, job demands), learning-related outcomes (skill utilization, self-efficacy), and strain (anxiety, depression) were compared. Three independent samples of call center employees were used, 2 cross-sectional (Ns=427 and 203) and 1 longitudinal (N=144). Initial analysis of the cross-sectional samples using structural equation modeling revealed that mediated models provided the best fit to the data. Skill utilization mediated the effect of control on depression, and depression partially mediated the effect of control on skill utilization. Longitudinal hierarchical regression analysis confirmed these findings. Results indicate that, in this occupational context learning reduces strain, strain inhibits learning, and job control is an important precursor of both these relationships.

"The very best of the millennium": Longitudinal research and the demand-control-(support) model.

This study addressed the methodological quality of longitudinal research examining R. Karasek and T. Theorell's (1990) demand-control-(support) model and reviewed the results of the best of this research. Five criteria for evaluating methodological quality were used: type of design, length of time lags, quality of measures, method of analysis, and nonresponse analysis. These criteria were applied to 45 longitudinal studies, of which 19 (42%) obtained acceptable scores on all criteria. These high-quality studies provided only modest support for the hypothesis that especially the combination of high demands and low control results in high job strain. However, good evidence was found for lagged causal effects of work characteristics, especially for self-reported health or well-being outcomes.

Impact of daily mood, work hours, and iso-strain variables on self-reported health behaviors.

Four hundred and twenty-two employees completed daily diaries measuring positive affect, negative affect, work hours, and health behaviors (snacking, smoking, exercise, alcohol, caffeine consumption) on work days over a 4-week period. In addition, measures of job demands, job control, and social support (iso-strain variables) were completed on 1 occasion. Multilevel random coefficient modeling was used to examine relationships between the job characteristics, daily work variables, and self-reported health behaviors. Results indicated a more important role for within-person daily fluctuations than for between-persons variations in predicting health behaviors. Whereas negative affect was negatively related to health behavior for both men and women, work hours had negative impacts for women only. Iso-strain variables showed few main effects and a modest number of interactions with daily variables (mainly for men). Findings point to the limited impact of stable features of work design compared to the effects of daily work stressors on health behaviors.

Turnover intention and emotional exhaustion "at the top": Adapting the job demands-resources model to leaders of addiction treatment organizations.

Compared with the large literature on subordinate employees, there are few studies of emotional exhaustion and turnover intention for organizational leaders. There is little research that has extended the job demands-resources (JD-R) model of emotional exhaustion to leaders. In this study, the authors adapted the JD-R framework to analyze data collected from a sample of 410 leaders of addiction treatment organizations. The authors considered whether two job demands (performance demands and centralization) and two job resources (innovation in decision making and long-range strategic planning) were associated with emotional exhaustion and turnover intention. The authors also examined whether emotional exhaustion fully or partially mediated the associations between the job-related measures and turnover intention. The results supported the partially mediated model. Both job demands were positively associated with emotional exhaustion, and the association for long-range strategic planning was negative. Emotional exhaustion was positively associated with turnover intention. Centralization and innovation in decision making were also directly associated with turnover intention. Future research should continue to examine this theoretical framework among leaders of other types of organizations using more refined measures of demands and resources.

Job characteristics and off-job activities as predictors of need for recovery, well-being, and fatigue.

Two empirical studies examined need for recovery (i.e., a person's desire to be temporarily relieved from demands in order to restore his or her resources) as a mediator in the relationship between poor job characteristics (high job demands, low job control) and high off-job demands, on the one hand, and fatigue and poor individual well-being, on the other hand. Multilevel data from a daily survey study in the health service sector (Study 1) showed that high job demands, low job control, and unfavorable off-job activities predicted a high need for recovery. Need for recovery in turn was negatively related to individual well-being. A large-scale survey with a representative sample of the Dutch working population (Study 2) confirmed these findings for fatigue. In both studies, need for recovery mediated the effects of job characteristics and off-job activities on fatigue and poor well-being, respectively.

Costs of simultaneous coping with emotional dissonance and self-control demands at work: Results from two German samples.

In the present study, we examine interactive effects of emotional dissonance (ED) and self-control demands (SCDs; impulse control, resisting distractions, and overcoming inner resistances) on emotional exhaustion, depersonalization, depressive symptoms, and absenteeism. We derived the prediction of interactive effects from the well-founded theoretical argument that both sources of work stress draw on and compete for a common limited regulatory resource. On the basis of 2 German samples (1 cross-sectional and 1 longitudinal sample; NTOTAL = 367), 7 of the 8 interactions tested were found to explain significant proportions of variance in all 4 outcomes considered over and beyond that accounted for by demographic characteristics, outcome stability (longitudinal sample), and main effects. Consistent with our hypotheses, the positive relations of 1 of both stressors (ED or SCDs) to psychological strain and absenteeism were amplified as a function of the other stressor. Theoretical and practical implications of the findings are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Emotional Labor Demands and Compensating Wage Differentials.

The concept of emotional labor demands and their effects on workers has received considerable attention in recent years, with most studies concentrating on stress, burnout, satisfaction, or other affective outcomes. This study extends the literature by examining the relationship between emotional labor demands and wages at the occupational level. Theories describing the expected effects of job demands and working conditions on wages are described. Results suggest that higher levels of emotional labor demands are associated with lower wage rates for jobs low in cognitive demands and with higher wage rates for jobs high in cognitive demands. Implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Railing for Safety: Job Demands, Job Control, and Safety Citizenship Role Definition.

This study investigated job demands and job control as predictors of safety citizenship role definition, that is, employees' role orientation toward improving workplace safety. Data from a survey of 334 trackside workers were framed in the context of R. A. Karasek's (1979) job demands-control model. High job demands were negatively related to safety citizenship role definition, whereas high job control was positively related to this construct. Safety citizenship role definition of employees with high job control was buffered from the influence of high job demands, unlike that of employees with low job control, for whom high job demands were related to lower levels of the construct. Employees facing both high job demands and low job control were less likely than other employees to view improving safety as part of their role orientation.

Self-control demands: A source of stress at work.

Recent developments in cognitive and social psychology suggest that self-control demands have an effect as a source of stress at work. Initial findings revealed that self-control demands were positively related to job strain. However, evidence is lacking so far as to whether self-control demands exert unique influences on strain. Consequently, in the present study different forms of self-control demands (impulse control, resisting distractions, overcoming inner resistances) were investigated in combination with role ambiguity as a well-established work stressor. The results showed that (a) the measured forms of self-control demands jointly contributed significant portions of incremental variance to the prediction of various measures of strain, and (b) each form was able to explain specific portions of variance in strain.

Display Rule "Regulators": The Relationship Between Supervisors and Worker Emotional Exhaustion.

This field study examined the effect of supervisory regulation of display rules--the rules about what kind of emotion to express on the job (R. Ekman, 1992; A. Rafaeli & R. I. Sutton, 1987)--on the emotional exhaustion of subordinates. On the basis of a sample of 940 call center employees, the authors found that worker emotional exhaustion varied across supervisors within jobs, suggesting that emotion work is influenced at the supervisory, rather than job, level. Moreover, the authors found that the importance supervisors place on interpersonal job demands of their workers was positively related to worker emotional exhaustion. Worker career identity moderated the interpersonal-job-demands--emotional-exhaustion relationship, but self-efficacy did not. Study conclusions and suggestions for future research are provided.

Life on the line: Job demands, perceived co-worker support for safety, and hazardous work events.

The present study of 334 United Kingdom trackside workers tested an interaction hypothesis. We hypothesized, drawing on the job demands-resources framework, that perceived support for safety (from senior managers, supervisors, and coworkers) as job resources would weaken the relationship between higher job demands and more frequent hazardous work events. Consistent with social impact theory, we predicted that perceived coworker support for safety would be particularly influential when trackside workers faced higher job demands. Moderated multiple regression showed that, of all three sources of perceived support for safety, perceived coworker support for safety was most important for keeping employees safe in the face of high job demands.

A multigroup analysis of the job demands-resources model in four home care organizations.

The job demands-resources (JD-R) model was tested in a study among 3,092 employees working in 1 of 4 different home care organizations. The central assumption in the model is that burnout develops when certain job demands are high and when job resources are limited because such negative working conditions lead to energy depletion and undermine worker motivation and learning opportunities, respectively. A series of multigroup structural equation modeling analyses provide strong evidence for the JD-R model. Specifically, results showed that job demands are primarily and positively related to the exhaustion component of burnout, whereas job resources are primarily related to cynicism (negatively) and professional efficacy (positively). The theoretical and practical implications of the JD-R model are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stressful Work, Psychological Job Strain, and Turnover: A 2-Year Prospective Cohort Study of Truck Drivers.

Based on a model that combines existing organizational stress theory and job transition theory, this 2-year longitudinal study examined antecedents and consequences of turnover among Dutch truck drivers. For this purpose, self-reported data on stressful work (job demands and control), psychological strain (need for recovery after work and fatigue), and turnover were obtained from 820 drivers in 1998 and 2000. In agreement with the model, the results showed that strain mediates the influence of stressful work on voluntary turnover. Also in conformity with the model, job movement to any job outside the trucking industry (i.e., interoccupational turnover) resulted in a larger strain reduction as compared to job movement within the trucking industry (intraoccupational turnover). Finally, strain was found to stimulate interoccupational turnover more strongly than it stimulated intraoccupational turnover. These findings provide a thorough validation of existing turnover theory and give new insights into the turnover (decision) process. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
