Much research into work-related stress is based on retrospective self-reports, whereas records made at the time could be more valuable. In this study the primary components of two models of work stress, Karasek's demand-control (DC) model and Siegrist's effort-reward imbalance (ERI), were assessed in trained nurses using ambulatory diaries and traditional questionnaire methods. The diaries were entered on small hand-held computers and the method used has been termed ecological momentary assessment (EMA), in which recordings are made in real time in the working environment. The participants were 36 nurses who completed standardized questionnaires evaluating ERI, strain (from DC model), and, over three shifts, computerized behavioural diaries that measured effort-demand, control, reward, and stress every 90 minutes on average, enabling determination of strain and ERI repeatedly in the work situation. A total of 674 observations were recorded. Using multilevel linear modelling, it was found that the questionnaire and computerized diary derived measures of strain (DC) and ERI were reliably correlated. In addition, the ambulatory measures of both strain (DC) and ERI correlated with ratings of stress taken at the same time. From this study it would appear that ambulatory diaries could be a powerful and flexible way of assessing work related stress and its putative determinants in a real life work setting.  相似文献

Abstract

Numerous tools have been developed that attempt to measure work-related stress and working conditions, but few practical instruments in the literature have been found to have a reliable psychometric factor structure. In the UK, the Health and Safety Executive (HSE) Management Standards (MS) Indicator Tool is increasingly used by organizations to monitor working conditions that can lead to stress. In Health and Safety Executive (2004), a factor analysis was conducted demonstrating the reliability of the scales. However, the authors acknowledged that direct reassessment of the same factor structure was impossible as the questionnaire was split into two separate modules for data collection. Furthermore, the tool is designed to enable comparisons between as well as within organizations to take place, yet reliability has only previously been tested at the individual level. The current study is the first to examine the factor structure of the HSE MS Indicator Tool using organizational-level data. Data collected from 39 UK organizations (N=26,382) was used to perform a first-order Confirmatory Factor Analysis (CFA) on the original 35-item seven-factor measurement scale. The results showed an acceptable fit to the data for the instrument. A second-order CFA was also performed to test if the Indicator Tool contains a higher order uni-dimensional measure of work-related stress. These findings also revealed an acceptable fit to the data, suggesting that it may be possible to derive a single measure of work-related stress. Normative data comprising tables of percentiles from the organizational data are provided to enable employers to compare their organizational averages against national benchmarks.  相似文献

Abstract

This study aimed to test whether curvilinearity would add explanatory power to the long-term relationships between job characteristics and mental well-being. The study was based on cross-sectional and longitudinal data from phases 3 and 5 of the Whitehall II sample (N=4154 for job satisfaction and 6000 for context-free mental well-being, mean follow-up 5.8 years). The curvilinear components of the job characteristics were introduced after controlling for the baseline outcome measure, demographic factors, and the linear measures of the job characteristics. The cross-sectional analyses showed only a curvilinear association with the expected U-shape between job demands and context-free mental well-being. The longitudinal analyses showed no curvilinear relationships between the job characteristics and context-free mental well-being. While small non-linear relationships were found between social support and decision latitude and job-related mental well-being, the shape of these relationships was the reverse of that expected. Post hoc analyses revealed that only the positive segment of the relationship between decision latitude and job satisfaction was significant, while both segments of the relationship between social support and job satisfaction were significant. The findings from this study, based on a large sample with high variety in working conditions, provide little support for the assumption of curvilinearity in the long-term relationship between psychosocial working conditions and mental well-being. This has practical implications, as if associations are linear this would indicate that it would be reasonable to take a population (rather than individually targeted) approach to stress management interventions.  相似文献

Transactional models of stress emphasize the importance of cognitive appraisal of potential stressors in the determination of the stress response. This appraisal can be modified by the use of techniques normally associated with cognitive therapy. The contribution of a specifically cognitive component when intervening in work-related stress has not been well evaluated to date. This research seeks to determine the effectiveness of stress management training in the treatment of the work-related effects of stress by comparing the role of modifying dysfunctional cognitions with the teaching of appropriate behavioural coping strategies. Participants were allocated to one of two intervention conditions or to a waiting list control group. Those in the intervention conditions received group stress management either with the focus on delivering cognitive therapy techniques or with the focus on behavioural coping skills. Measures of general health were taken at the beginning and end of intervention and at 3-month follow-up. Participants in the cognitive therapy groups who were reporting symptoms of general ill-health at the start of the intervention showed a significant improvement at follow-up. Cognitive therapy appears to have been an effective intervention in work-related stress. Those in the behavioural group showed a smaller but still clinically effective improvement. Results are discussed in terms of methodological issues and implications for future research. It is suggested that changes in cognitive appraisal may need to be developed.  相似文献

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.  相似文献

Abstract

The Effort-Reward Imbalance (ERI) model comprises both situational components (i.e. effort and reward) and a person-specific component (overcommitment). The aims of this study were to investigate the role of theoretically and historically linked personality variables (i.e. overcommitment and Type A personality) within the ERI model and to expand and extend the ERI model by investigating the contribution of individual reward components to both psychological (i.e. psychological distress) and attitudinal (i.e. affective commitment) employee strain indicators. A total of 897 police officers from a large Australian police agency participated in the study. The results provided no evidence of an interaction effect of effort or reward with overcommitment. The Type A variables did, however, make significant contributions and were involved in a number of interactions, suggesting that the person-specific component of the ERI model could be extended with the Type A personality profile. The findings also suggest that the esteem component of reward has the greatest relevance to employee outcomes, although tangible aspects of reward are more likely to act as a buffer of perceived work demand.  相似文献

Job stress can lead to various system dysfunctions, but until now no reliable biomarkers for its assessment have been identified. Allostatic load (AL) is an index that enables the cumulative effect on the body of chronic stress to be assessed, and is derived from a set of relevant biological measures. In this study, a 13-parameter index (building on the original 10-item index) was used to examine the relationship between job strain and AL. Participants were 1219 healthy Chinese employees. Job strain was measured using the Job Content Questionnaire, and AL was assessed by various possible stress responses, including blood pressure, cholesterol, indicators of glucose metabolism, and hormone and inflammation markers. AL in the high job strain group differed sharply from that in the low job strain group. The AL score was positively associated with age and educational level. Several individual parameters also differed between the two groups. Men scored significantly higher on AL and cardiovascular and metabolic health outcomes, whereas for women the associations appeared in the biological indicators. Analyses indicated that decision latitude (DL) and job demands were significantly related to AL. Job demands correlated significantly with the primary biological indicators and DL with the secondary health outcomes. In conclusion, this study provides evidence of the value of measuring allostatic load in assessing the chronic effects of job stress.  相似文献

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.  相似文献

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.  相似文献

This study assessed the mental health, job satisfaction and sickness absence of comparative groups of 236 managers and 377 shopfloor workers in the brewing industry in Scotland and northern England. The results showed significant differences between the groups' scores on type A behaviour, locus of control, job satisfaction, and number of incidents of sickness absence. Multiple regression was used to elucidate similarities and differences between managers and shopfloor workers in the predictors of stress outcomes.  相似文献
