Helping people to sort it out: The role of social support in the Job Strain Model

This paper reports three studies of occupational stress investigating the role of social support as an intervening variable in the Job Strain Model (Karasek, 1979). A computer simulated mail-sorting work environment was used to assess the effect of demands, control and social support on measures of strain, satisfaction, and perceived and actual task performance. The first experiment ( N =60) tests the basic Job Strain Model by manipulating levels of task demand and control. The second experiment ( N =120) compares high and low levels of two types of social support (informational support and emotional support) to determine whether and how they interact with extreme conditions of the Job Strain Model (high strain and low strain). The final experiment ( N =90) investigates positive and negative forms of social support (praise and criticism) in relation to extreme job strain conditions. Results show that the job strain model is consistent with the stress and performance data, although stress showed no Demand 2 Control interaction. Social supports increased arousal, satisfaction and perceived performance, but did not affect stress or task performance. Moreover, contrary to buffer theories, social supports did not interact with the job strain variables. Congruence between preferred and experienced emotional support levels also predicted performance.     

Modelling relationships between job stressors and injury and near-miss outcomes for construction labourers

Construction work is an inherently dangerous occupation and exposure to additional job stressors is likely to exacerbate the level of danger, increasing workers’ risk for injury. Thus, it is important to identify and then reduce worker exposure to extraneous job stressors. This study examines the relationships between a variety of job stressors and injury or near-miss outcomes among construction workers. Self-reported questionnaire data collected from 408 construction labourers (male and female) via telephone interview were analysed using structural equation modelling. A theoretical model was tested whereby work stressors, classified into three groups, could be related, either directly or indirectly through the mediating effects of physical or psychological symptoms/strain, to self-reported injuries and near misses. Ten of the 12 work-related stressors were found to be directly related to either injury or near misses, including: job demands, job control, job certainty, training, safety climate, skill under-utilization, responsibility for the safety of others, safety compliance, exposure hours, and job tenure. Other stressors (i.e. harassment/discrimination, job certainty, social support, skill under-utilization, safety responsibility, safety compliance, tenure in construction) were indirectly related to injuries through physical symptoms or indirectly related to near misses through psychological strain. There was no support for the modelled gender differences. Implications for health and safety on construction sites are discussed.     

Beyond demand and control: The contribution of organizational risk factors in assessing the psychological well-being of health care employees

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.     

Bricks without clay: On urban myths in occupational health psychology

Abstract

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 investigation of competencies within professional domains

Nowadays much attention is paid to the concept of competence in labour organizations and in higher education. This paper investigates different approaches to investigate competencies for educational purposes. After a discussion of various approaches, the authors present a case study that was conducted to compose a competency profile for the Faculty of Economics, Business and Public Administration of the Open University of the Netherlands. In this case study, several approaches were combined. The design and the results of the case study are described. The paper concludes with a discussion on the advantages and disadvantages of the applied approach.     

Gender bias in job referrals: An experimental test

Employee referral programs, while efficient for the employer, have been shown to amplify sex-based occupational segregation in labor markets because of the tendency of workers to refer people of the same gender. We implement a controlled laboratory experiment that precludes any concern for network composition or reputation effects in referral choice. In this way, our experimental design allows us to disentangle statistical discrimination, preferences, and implicit same-gender bias. Our data suggest that women tend to favor women when choosing a candidate, whereas men do not attach much importance to the gender of potential candidates. We deduce from our various treatments that same-gender referrals are mainly driven by preferences in competitive environments and implicit same-gender bias in cooperative environments. Our findings add to the existing literature by highlighting that gendered networks alone fail to explain the observed gender homophily in referred-referrer pairs.     

Displacement in new economy labor markets: Post-displacement wage loss in high tech versus low tech cities

While scholars and politicians tout education as the salve to employment disruptions, we argue that the geography of the new economy, and the social closure mechanisms that geography creates, may be just as important as individuals’ characteristics for predicting post-displacement wage loss (or gain). We use data from the 2012 Displaced Workers ement of the Current Population Survey and from the 2010 United States Census to test hypotheses linking local labor markets in different industrial contexts to post-displacement wage loss. Our results point to age as a closure mechanism, and to the partially protective effect of education in high-tech versus low-tech economic sectors. This study is the first to use national level data to examine how employment in high-tech cities influences post-displacement wages. These findings are relevant both for theorizing about the new economy and for public policy.     

Millennial Generation’s Job Search Activity and Job Quality: Findings from the National Longitudinal Survey of Youth

Job quality of young adults in the USA has been eroding since the Great Recession of 2007. The intensity of job search activities are a well-established predictor of employment, yet little is known whether job search intensity is associated with the quality of subsequent secured employment. This study examined the 2013 sample of the National Longitudinal Survey of Youth (NLSY) (N?=?1566), which follows a sample of American youth born between 1980 and 1984 and contains reliable measures of job search activities and job quality. Multivariate regression models examined whether job search activities were associated with pay, paid vacation days, full time job status, regular work schedule, and availability of a union contract, controlling for demographic factors. The results demonstrated that the number of job search activities completed was positively associated with multiple positive employment-related outcomes. Programs to assist individuals in the job search process may benefit from these results when offering strategies for successfully securing employment of a higher quality that may offer increased quality of life.     

The Consequences of Job Displacement for Health: Moderating Influences of Economic Conditions and Educational Attainment

This paper examines the impact of worker displacement on health in the United States from 1975–2004, especially the extent to which the impact of displacement on health varies according to the economic conditions in the year of displacement and the education level of the displaced worker. Findings from ordered probit and fixed effects models suggest that the negative impact of displacement on health is exacerbated by a higher unemployment rate at the time of displacement and for displaced workers with a college degree.     

Does positivity enhance work performance?: Why,when, and what we don’t know

There is evidence, spanning many decades of research, that the subjective well-being (SWB) of workers, including life satisfaction, job satisfaction, and positive affect, positively correlates with the performance of workers and organizations. However, the size of the relationships is typically small to moderate. In this review we address the question of why the relationships are not stronger. We first review evidence of a relationship moving from well-being to performance through various pathways. Workers who are high in SWB are now understood to have: 1. better health, 2. lower absenteeism, 3. greater self-regulation, 4. stronger motivation, 5. enhanced creativity, 6. positive relationships, and 7. lower turnover. Each of these variables can predict individual and organizational performance. However, the sheer number of known and possible pathways means the relationships are bound to be complex, and there are mitigating conditions at every turn. Thus, second, we review the evidence of moderators of these mediators, hypothesizing when a happier workforce is a more productive one, and when not. Future research is needed to firmly establish the pathways from different types of SWB through the mediators to metrics of performance, to further establish the moderating conditions in which these relations are most likely to occur, and to evaluate how much SWB is needed to maximize effectiveness. We end by urging scholars to conduct this future research using the highest standards of scientific integrity.
