Job strain and evolution of mental health among nurses.

The objective of this 2nd phase of a 2-year study among female nurses was to provide further empirical validation of the demands-control and social support model. The association of job strain with psychological problems and the potential modifying role of social support at work were examined. A questionnaire was sent at the workplace to 1,741 nurses. The same associations were found between psychological demands, decision latitude, and a combination of the 2 with psychological distress and emotional exhaustion for current exposure and for cumulative exposure. Social support had a direct effect on these psychological symptoms but did not modify their association with job strain. Longitudinal and prospective data are needed to study the occurrence and persistence of health problems when exposure is maintained or retrieved.

Job control and job strain: A test of three models.

Examined the relationship between job control and job strain. Three models of that relationship provide a framework for the study hypotheses: (H1) Control is inversely related to job strain, (H2) job demands interact with job control such that job strain will be highest when job demands are high and job control is low, and (H3) strain increases as the discrepancy between actual and desired levels of job control increases. Study participants (N?=?316) were health care workers in 2 hospitals in the northeastern US. Objective measures of job control and job demands were obtained through supervisor evaluations of incumbents' job characteristics, and perceptual measures were obtained through incumbents' self-reports. Results provide support for Hypotheses 1 and 3; little support was found for an interaction between job control and job demands. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Role of Job Security in Understanding the Relationship Between Employees' Perceptions of Temporary Workers and Employees' Performance.

On the basis of psychological contract and social cognition theories, the authors explored the role of full-time employees' perceived job security in explaining their reactions to the use of temporary workers by using a sample of 149 full-time employees who worked with temporaries. As hypothesized, employees' perceived job security negatively related to their perceptions that temporaries pose a threat to their jobs, but it did not relate to their perceptions that temporaries are beneficial. Furthermore, employees' job security moderated the relationships between benefit and threat perceptions and supervisor ratings of job performance. For those with high job security, there was a positive relationship between benefit perceptions and performance. For those with low job security, there was a negative relationship between threat perceptions and performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Job Strain, Job Insecurity, and Health: Rethinking the Relationship.

Job strain (high demands and low control) is a widely used measure of work stress. The authors introduce a new way of looking at work stress by combining job strain with job insecurity, a combination increasingly prevalent in contemporary economies, using data from a cross-sectional survey (N = 1,188) of mid-aged Australian managers and professionals. Those reporting both strain and insecurity showed markedly higher odds for mental and physical health problems (depression: odds ratio [OR] 13.88, 95% confidence interval [CI] 5.67-34.01; anxiety: OR 12.88, CI 5.12-32.39; physical health problems: OR 3.97, CI 1.72-9.16; and poor self-rated health: OR 7.12, CI 2.81-18.01). Job strain and insecurity showed synergistic associations with health, and employees experiencing both could be at heightened health risk.

Job characteristics and college performance and attitudes: A model of work-school conflict and facilitation.

The processes linking job characteristics to school performance and satisfaction in a sample of 253 full-time college students were examined from 2 role theory perspectives, 1 of which emphasized resource scarcity and the other resource expansion. Model tests using structural equation modeling showed that 2 resource-enriching job characteristics, job-school congruence and job control, were positively related to work-school facilitation (WSF). Two resource-depleting job characteristics, job demands and work hours, were positively related to work-school conflict (WSC), and job control was negatively related to WSC. In turn, WSF was positively related to school performance and satisfaction, and WSC was negatively related to school performance. Both WSF and WSC mediated the relationship between the job characteristics and school outcomes. There was no evidence of interactive effects between enriching and depleting job characteristics on interrole processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Job mobility, its determinants, and its effects: Longitudinal data from the Maastricht cohort study.

This prospective study of 12,140 employees examined the effects of work characteristics and situational, psychological, and health aspects on job mobility. Before job change, the mobility group reported significantly more conflicts with the supervisor, higher physical and emotional strain, higher degree of job insecurity, lower job satisfaction, and lower degree of commitment compared with employees who did not change jobs. After job change, the mobility group reported improved autonomy, task diversity, decreased occurrence of conflicts with the supervisor, decreased physical and emotional strain, and improved training possibilities and job security than before the change. Changing jobs had a positive effect on employees with respect to job perception and job satisfaction and led to reduced fatigue and need for recovery.

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).

Job insecurity in white-collar workers: Toward an explanation of association with health.

This article describes 2 studies that examined changes in psychosocial work characteristics (job strain model) and health-related behaviors as potential explanations of the job insecurity–health relationship in a longitudinal cohort of white-collar British civil servants. Job insecurity arising from anticipation of change was associated with a modest increase in self-reported morbidity, whereas chronic job insecurity was associated with some adverse physiological changes. Anticipation of change and chronic job insecurity were associated with adverse changes in other psychosocial work characteristics, but few changes were significant and consistent across both exposure groups. Changes in health-related behaviors associated with either exposure were slight. Apart from a minor role for social support at work in both sexes and a modest role for job demands in women, adverse changes in these factors explain little of the job insecurity–health relationship.

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.

Happy, healthy, and productive: The role of detachment from work during nonwork time.

Mentally distancing oneself from work during nonwork time can help restore resources lost because of work demands. In this study, we examined possible outcomes of such psychological detachment from work, specifically well-being and job performance. Although employees may need to mentally detach from work to restore their well-being, high levels of detachment may require a longer time to get back into “working mode,” which may be negatively associated with job performance. Our results indicate that higher levels of self-reported detachment were associated with higher levels of significant other-reported life satisfaction as well as lower levels of emotional exhaustion. In addition, we found curvilinear relationships between psychological detachment and coworker reported job performance (task performance and proactive behavior). Thus, although high psychological detachment may enhance employee well-being, it seems that medium levels of detachment are most beneficial for job performance.

Gender differences in job strain, social support at work, and psychological distress.

Using the demand-control-support model of job strain, the authors examined gender differences in the relationship between psychosocial work exposures and psychological distress in a cross-sectional sample of 7,484 employed Canadians. Compared with low-strain work, high-strain and active work were associated with a significantly higher level of distress in both men and women. Differences in psychological distress in relation to psychosocial work exposures were greater for men than for women. Low social support was associated with higher distress across all categories of job strain, and the combined effect of low social support and high job strain was associated with the greatest increase in distress. This pattern was similar in men and women. This study suggests that psychosocial work exposures may be a more significant determinant of psychological well-being in male workers compared with female workers.

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.

Work stress and health

OBJECTIVES: This article describes work stress experienced by the employed population. It examines associations between job strain, job insecurity, physical demands, low co-worker support and low supervisor support, and four health outcomes: migraine, work injury, high blood pressure and psychological distress. DATA SOURCE: The data are from the household component of the 1994/95 National Population Health Survey conducted by Statistics Canada. Results are based on a sample of 9,023 employed Canadians aged 18 to 64. ANALYTICAL TECHNIQUES: Multivariate analyses were used to estimate associations between work stress and health problems, while controlling for other potential stressors. MAIN RESULTS: Among men, job strain was associated with migraine and psychological distress, and among women, with work injury. Job insecurity was associated with migraine among women. High physical demands were related to work injury in both sexes. Low co-worker support was related to migraine among men, and to work injury and psychological distress among women.     

The Role of Acceptance and Job Control in Mental Health, Job Satisfaction, and Work Performance.

Acceptance, the willingness to experience thoughts, feelings, and physiological sensations without having to control them or let them determine one's actions, is a major individual determinant of mental health and behavioral effectiveness in a more recent theory of psychopathology. This 2-wave panel study examined the ability of acceptance also to explain mental health, job satisfaction, and performance in the work domain. The authors hypothesized that acceptance would predict these 3 outcomes 1 year later in a sample of customer service center workers in the United Kingdom (N = 412). Results indicated that acceptance predicted mental health and an objective measure of performance over and above job control, negative affectivity, and locus of control. These beneficial effects of having more job control were enhanced when people had higher levels of acceptance. The authors discuss the theoretical and practical relevance of this individual characteristic to occupational health and performance.

Work conditions, mastery and psychological distress: are housework and paid work contexts conceptually similar?

This research examined how the conditions of paid work and unpaid housework were related to women's sense of mastery, depressed mood and anxiety. The data for these analyses were taken from the American Changing Lives (ACL) survey (House, 1986). This research draws from a subsample of 992 black and non-Hispanic white women aged 24 to 59. The conditions of work on the job and in the home are not consistently related to women's psychological functioning. Among employed women, decision latitude on the job is related to depressed mood indirectly through their sense of mastery; the physical demands of work are directly related to depressed mood, but the effect is stronger among employed women than employed homemakers. In contrast, decision latitude at home is directly related to depressed mood among homemakers; the physical demands of housework are related to depressed mood only indirectly through women's sense of mastery. This pattern is repeated in the relationship between anxiety and decision latitude both at home and on the job, and in the relationship between anxiety and physical demands of work on the job. Both unpaid housework and paid work are forms of productive activity, but these findings suggest they are not a ubiquitous entity with similar effects for all women. Rather the context of work shapes the effect of work conditions for women's psychological functioning.     

Job Strain or Healthy Work: A Question of Task Design.

Objectively evaluated task requirements were used to classify jobs causing high strain, low strain, and jobs conducive to personal development. Effects of these job characteristics on psychophysiological outcomes were tested in 241 employees by using 24-hr ambulatory assessment of blood pressure (BP), heart rate, and mood. Self-reports about job characteristics showed that employees working in jobs conducive to personal development perceived the highest job demands and decision latitude. They also showed a healthy cardiovascular behavior with increased diastolic BP at work and its strong unwinding at night. Although self-reports about job characteristics did not differ between low- and high-strain jobs, employees exposed to high-strain jobs had higher systolic and diastolic BP during work and more often a disturbed relaxation ability.

Change in job strain and progression of atherosclerosis: The Cardiovascular Risk in Young Finns study.

[Correction Notice: An erratum for this article was reported in Vol 16(2) of Journal of Occupational Health Psychology (see record 2011-06502-001). The order of authorship was listed incorrectly. The correct order is listed in the correction.] Evidence of the association between job strain, that is, a combination of high psychological demands and low job control, and markers of atherosclerosis is mixed, but few studies with repeat measures are available. The purpose of this study was to examine cross-sectional and longitudinal associations between job strain and atherosclerosis. The participants were 335 men and 374 women from the prospective Cardiovascular Risk in Young Finns study (mean age 38.5 years). Two sequential measurements of job strain and carotid intima-media thickness (IMT) were analyzed. No cross-sectional or longitudinal association between job strain and IMT was observed in women. In men, a cross-sectional association was found in 2001, but not in 2007. No dose-response effect was visible, nor a simple association between progression of job strain and progression of IMT. Instead, a more complex pattern of correlation was found in men with large decreases in job strain being associated with slower progression of IMT and combined decreases in job control and demands (a change toward passive jobs) being associated with greater IMT progression. These data suggest that temporal changes in job demands and control are associated with IMT in men via multiple mechanisms. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Gendered Work Conditions, Health, and Work Outcomes.

This cross-sectional study of nonfaculty university employees examined associations among gendered work conditions (e.g., sexism and discrimination), job demands, and employee job satisfaction and health. Organizational responsiveness and social support were examined as effect modifiers. Comparisons were made by gender and by the male-female ratio in each job category. The relationship of gendered conditions of work to outcomes differed on the basis of respondents' sex and the job sex ratio. Although the same predictors were hypothesized for job satisfaction, physical health, and psychological distress, there were some differing results. The strongest correlate of job satisfaction was social support; perceived sexism in the workplace also contributed for both men and women. Organizational factors associated with psychological distress differed between female- and male-dominated jobs. (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)
