Increasing the probability of finding an interaction in work stress research: A two‐wave longitudinal test of the triple‐match principle

Research into work stress has attempted to identify job resources that can moderate the effects of job demands on strain. The recently developed triple‐match principle (TMP) proposes that job demands, resources, and strain can be conceptualized as being composed of cognitive, emotional, and physical dimensions. When a psychological imbalance is induced by job demands, individuals activate corresponding resources to reduce the effects of the demands. A closer match occurs when the resources are processed in the same psychological domain as the demands. The further away from a match, the less likely an interactive effect will become. Put simply, the likelihood of finding an interactive effect between job demands and job resources is greatest when demands, resources, and strain are based on qualitatively similar dimensions (i.e. cognitive, emotional, and physical). For example, emotional support from colleagues is likely to buffer the effects of emotional demands on emotional exhaustion. The TMP was tested in a sample of 179 Australian police officers in a two‐wave longitudinal study. The likelihood of finding an interactive effect was related to the degree of match between job demands, job resources, and strain with 33.3% of triple‐match interactions significant, 22.2% when there was a double‐match, and 0.0% when there was no match. These findings lend support to the TMP as a guiding framework, for research, to explore possible interactive effects in work stress research, and for practice, to inform interventions matching resources to occupational demands, to offset strain.     

Perceived Emotional Demands–Abilities Fit

The purposes of this paper are to introduce the concept of perceived emotional demands–abilities (ED–A) fit and develop theory about how it relates to other fit perceptions as well as employee well‐being and performance outcomes. ED–A fit is defined as the perceived congruence or match between the emotional demands of the job and one's abilities to meet those demands. In two studies using occupationally diverse samples from Western and Eastern cultures, we empirically distinguished perceived ED–A fit from other fit perceptions (i.e. person–organisation, demands–abilities, needs–supplies, person–group, person–supervisor). In addition, across the two studies, we found that perceived ED–A fit accounted for incremental variance in job satisfaction, work tension, felt inauthenticity, burnout, self and supervisor ratings of job performance, and psychological need satisfaction, controlling for the effects of other fit perceptions.     

The role of matching job resources in different demanding situations at work: A vignette study

This study examines human service employees' beliefs about the availability, relevance, and use of specific types of job resources (i.e. cognitive, emotional, and physical) in similar types of demanding situations at work. To gain a better understanding of these intra‐psychic processes assumed to underlie the relation between job demands, job resources, and job‐related outcomes, a quasi‐experimental survey study with vignettes was developed. Results showed that different patterns could be observed between the availability, relevance, and use of matching and non‐matching job resources in a physically demanding situation at work. No such differences were observed in a cognitively and emotionally demanding job. Further, it was shown that there generally seems to be a dominant role for emotional job resources in the job stress process, whereas the role of physical job resources and, to a lesser extent, cognitive job resources appears much weaker and mainly restricted to corresponding types of job demands. Finally, results suggested that employees who are faced with a particular type of job demands may take advantage of both matching and non‐matching job resources, implying that the ‘matching hypothesis’ is a probabilistic rather than a static principle.     

Extending the demands‐control model: A daily diary study of job characteristics,work‐family conflict and work‐family facilitation

Using personal digital assistants, 91 parents employed in non‐professional occupations were surveyed for 14 consecutive days about their job characteristics and work‐family experiences. We found significant daily variation in work‐to‐family conflict (WFC) and work‐to‐family facilitation (WFF) that was predictable from daily job characteristics. Higher levels of WFC were associated with greater job demands and control at work. Contrary to the demands‐control model ( Karasek, 1979 ), these two job characteristics interacted such that the relationship between demands and WFC was stronger when control was high. We also found that demands were negatively related and control and skill level positively related to WFF. The results suggest ways in which jobs may be redesigned to enhance individuals' work‐family experiences.     

The Relation of Self‐Control Demands to Job Strain: The Moderating Role of Organisational Commitment

Drawing on recent theoretical developments in cognitive and social psychology, self‐control demands were introduced as a new source of stress at work. Affective organisational commitment was expected to operate as a buffer in the relation between self‐control demands and indicators of job strain. Data provided by 260 nurses in homes for elderly people revealed both significant relationships of self‐control demands and commitment to a broad spectrum of strain indicators that included not only self‐report measures (burnout, psychosomatic complaints, intentions of quitting), but also a measure of absenteeism. Self‐control demands were positively related to all indicators of job strain, whereas the associations were negative for affective commitment. In addition, the results provided clear evidence for the buffer hypothesis of commitment. The positive relations of high self‐control demands to all strain indicators were attenuated as a function of affective commitment. The results suggest that the buffer effect of commitment is mainly due to stress‐contingent appraisal processes rendering highly committed employees less vulnerable to the adverse effects of high stress.     

Inability to Withdraw from Work as Related to Poor Next‐Day Recovery and Fatigue among Women

Recovery from work stress is crucial in avoiding stress‐related ill‐health. The aim of this longitudinal study was to investigate whether processes that prolong the mental exposure to work stressors, such as inability to withdraw from work (IW), the core construct in overcommitment, predicts fatigue and poor next‐day recovery 6 months later over what is predicted by job control and job demands. Self‐ratings in questionnaires were completed by 160 women working in dental care at two time points, 6 months apart. Job demands, job control, and IW were used to predict fatigue and poor next‐day recovery, respectively. Multiple regression analyses show that having children living at home, high job demands, and high IW were associated with fatigue 6 months later. Job demands and IW, but not having children at home, predicted poor next‐day recovery. Mediation analyses using a bootstrapping procedure indicated that IW partly mediated the relationship between job demands and fatigue and between job demands and next‐day recovery. These findings highlight the importance of considering IW in relation to fatigue and recovery from work and that such factors should be included in interventions targeting work‐related stress.     

Testing the Triple‐Match Principle in the Technology Sector: A Two‐Wave Longitudinal Panel Study

The present study investigates the issue of match between job demands and job resources in the prediction of changes in job‐related well‐being outcomes as outlined by the Demand‐Induced Strain Compensation (DISC) model. Job demands, resources, and well‐being outcomes are considered to be multidimensional constructs comprising physical, cognitive, and/or emotional components. The Triple‐Match Principle (TMP) proposes that the strongest, interactive relationships between job demands and resources are observed when demands, resources, and outcomes are based on identical dimensions. This principle was tested using a two‐wave longitudinal panel study among 720 Belgian employees in the technology sector. Analyses were conducted with cross‐lagged structural equation modeling, and results tend to confirm the matching hypothesis. Specifically, the likelihood of finding valid interaction effects was nearly linearly related to the degree of match between demands, resources, and outcomes. Generalisability of the TMP in the technology sector was shown. Practically, findings indicate that enhancing specific, matching, job resources enables employees to deal with corresponding high job demands to improve employee well‐being.     

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.     

Resources and time pressure as day‐level antecedents of work engagement

This diary study adds to research on the Job Demands‐Resources model. We test main propositions of this model on the level of daily processes, namely, additive and interaction effects of day‐specific job demands and day‐specific job and personal resources on day‐specific work engagement. One hundred and fourteen employees completed electronic questionnaires three times a day over the course of one working week. Hierarchical linear models indicated that day‐specific resources (psychological climate, job control, and being recovered in the morning) promoted work engagement. As predicted, day‐specific job control qualified the relationship between day‐specific time pressure and work engagement: on days with higher job control, time pressure was beneficial for work engagement. On days with lower job control, time pressure was detrimental for work engagement. We discuss our findings and contextualize them in the current literature on dynamic and emergent job characteristics.     

Job stress and coping strategies in patients with subjective food hypersensitivity

Lind, R., Lillestøl. K., Valeur, J., Eriksen, H. R., Tangen, T., Berstad, A. & Arslan Lied, G. (2009). Job stress and coping strategies in patients with subjective food hypersensitivity. Scandinavian Journal of Psychology, 51, 179–184. Psychological distress may be causally related to multiple, unexplained somatic symptoms. We have investigated job stress, coping strategies and subjective health complaints in patients with subjective food hypersensitivity. Sixty‐four patients were compared with 65 controls. All participants filled in questionnaires focusing on job stress, job demands and control, work environment, coping strategies and subjective health complaints. Compared with controls, patients scored significantly lower on job stress and job demands, and significantly higher on authority over job decisions. Coping strategies and satisfaction with work environment did not differ significantly between the two groups, but the patients reported significantly more subjective health complaints than the controls. Scores on job stress and job demands were generally low in patients with subjective food hypersensitivity. It is unlikely, therefore, that the patients’ high scores on subjective health complaints are causally related to the work situation.     

人事选拔决策过程的匹配评价研究: 基于策略捕捉技术

传统的人事选拔是以胜任力或者说是人－职匹配为基础的,即强调基于胜任力,但研究者和实践者们越来越多的强调人－组织匹配在人事选拔中的重要性,即强调人事选拔过程中招募者匹配评价的多维性。本研究通过实验运用策略捕捉技术,检验多种职位特征和不同层次的匹配评价对选拔雇佣结果的影响。通过HLM分析结果发现四种匹配类型需要－供给匹配、要求－能力匹配、个性匹配和价值观匹配对雇佣决策都有显著的独立主效应,招募者在长期招募比短期招募中更多依靠个性匹配来评价应聘者,招募者在对管理类职位更多依靠价值匹配来进行评价,而对专业类职位则更多依靠要求－能力匹配进行评价。     

Work stress and employee well‐being: The critical role of Zhong‐Yong

In the pursuit of well‐being at work, work stress is always an inescapable challenge. However, existing research shows that the relationships between work stress and employee outcomes are inconsistent, which indicates that the concept of work stress needs further investigation. Moreover, Zhong‐Yong serves as a cognitive strategy to coping with stress as well as being a pivotal life wisdom and practical rationality. Using a questionnaire survey, this study explores the relationship between work stress, employee well‐being, and Zhong‐Yong beliefs. The work stress was classified into challenge‐ and hindrance‐related stress while emotional exhaustion and job satisfaction were used as well‐being indicators. Using a sample of 394 employees from private enterprises in Taiwan as subjects, the results show that (1) hindrance‐related stress is destructive to employee well‐being; (2) challenge‐related stress is positively associated with emotional exhaustion but has no significant relation with job satisfaction; (3) Zhong‐Yong beliefs mitigate the harm from hindrance‐related stress on employee well‐being; and (4) Zhong‐Yong beliefs weaken the negative effects of challenge‐related stress on emotional exhaustion, and transform challenge‐related stress into eustress for job satisfaction.     

An intra‐individual test of the demands‐control model: A weekly diary study of psychological strain in portfolio workers

Twenty‐five years of research on Karasek's job strain model has produced evidence that jobs involving high demands, low control and low social support may produce psychological strain. The present study takes this research in a new direction by using a time‐sampling methodology with a group of portfolio workers (self‐employed individuals who work for multiple clients) to examine whether working weeks that involve more of these characteristics are associated with greater psychological strain. The study also examines whether workers' optimism moderates the intra‐individual relationship between job characteristics and strain. Every week for 26 weeks, 65 portfolio workers completed a diary containing measures of work demands, job control, social support and strain. Multi‐level analyses supported the additive but not the interactive form of the job strain model. However, differences in portfolio workers' optimism moderated an interactive effect of weekly demands and control on anxiety and depression, such that the highest levels of strain were experienced by pessimists under conditions of low control and high demands. The results suggest that psychological strain can vary with temporal variations in job characteristics and that a person‐situation approach is appropriate for understanding these dynamics.     

Psychosocial safety climate as a precursor to conducive work environments,psychological health problems,and employee engagement

We constructed a model of workplace psychosocial safety climate (PSC) to explain the origins of job demands and resources, worker psychological health, and employee engagement. PSC refers to policies, practices, and procedures for the protection of worker psychological health and safety. Using the job demands–resources framework, we hypothesized that PSC as an upstream organizational resource influenced largely by senior management, would precede the work context (i.e., job demands and resources) and would in turn predict psychological health and work engagement via mediation and moderation pathways. We operationalized PSC at the school level and tested meso‐mediational models using two‐level (longitudinal) hierarchical linear modelling in a sample of Australian education workers (N = 209–288). Data were repeated measures separated by 12 months, nested within 18 schools. PSC predicted change in individual psychological health problems (psychological distress, emotional exhaustion) through its relationship with individual job demands (work pressure and emotional demands). PSC moderated the relationship between emotional demands and emotional exhaustion. PSC predicted change in employee engagement, through its relationship with skill discretion. The results show that the PSC construct is a key upstream component of work stress theory and a logical intervention site for work stress intervention.     

Testing the triple-match principle among technology employees

The triple-match principle (TMP) proposes that the strongest, interactive relationships between job demands and job resources are observed when job demands, job resources and job-related outcomes are based on qualitatively identical dimensions. This principle is tested with regard to three outcomes: cognitive failure, emotional exhaustion, and physical health complaints. Data were collected in a large sample of employees in the technology sector (n = 1533). Results demonstrate that the positive association between emotional job demands and emotional exhaustion is compensated by the availability of emotional job resources. No triple-match interactions are found with regard to cognitive failure or physical health complaints. In line with the TMP, results show that the likelihood of finding theoretically valid interactions is related to the degree of match between job demands, job resources, and outcomes.     

A Longitudinal Test of the Job Demands‐Resources Model among Australian University Academics

A longitudinal test of the Job Demands‐Resources (JD‐R) model of work stress and engagement ( Bakker & Demerouti, 2007 ; Demerouti et al., 2001 ) was conducted in a sample of Australian university academics (N= 296). The aim was to extend the JD‐R model by (1) determining how well job demands (work pressure, academic workload) and job resources (procedural fairness, job autonomy) would predict psychological strain and organisational commitment over a three‐year period, and (2) incorporating longitudinal tests of reversed causation. The results of SEM analyses showed that Time 1 resources directly predicted Time 2 strain and organisational commitment, but that Time 1 demands predicted Time 2 strain only indirectly via job resources. We did not find evidence for reversed causation. We discuss possible mediators of the relationships between working conditions and work stress outcomes, and the practical implications of the results.     

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.     

Worked to Death: The Relationships of Job Demands and Job Control with Mortality

Despite recent calls in the literature to examine the effects of the occupational context on physiological outcomes, such as mortality, little research has accumulated on this front. Thus, the purpose of this study is to investigate the interactive relationship between job demands, control, and death. Drawing from the job design, stress, and epidemiology literatures, we argue that job demands will be positively related to mortality under conditions of low control, and negatively related to mortality under conditions of high control. We tested our hypothesis using a 7‐year time‐lagged design in a sample of 2,363 individuals from the Wisconsin Longitudinal Study. Our results supported our hypothesis, with results showing that for individuals in low control jobs, high job demands are associated with a 15.4% increase in the odds of death compared to low job demands. For those in high control jobs, high job demands are associated with a 34% decrease in the odds of death compared to low job demands. Supplementary analyses revealed a similar pattern predicting body mass index in the group of surviving individuals. We discuss the implications of these findings for theory and practice, while proposing several avenues for future research.     

How job characteristics relate to need satisfaction and autonomous motivation: implications for work effort

To explore the motivational potential of job design, we linked job demands and job resources, as defined in the job demands–resources model, to the motivational process defined in self‐determination theory. Specifically, we introduced basic need satisfaction and autonomous motivation as consecutive process variables mediating the relationship between job design and work effort. We tested this model by means of structural equation modeling in a sample of 689 employees. The comparison of several competing models provided support for the hypothesized model. We conclude that job demands thwart and job resources promote the fulfillment of 3 psychological needs. High levels of need satisfaction, in turn, are associated with autonomous motivation and, therefore, with high levels of effort.     

Professional efficacy,exhaustion, and work characteristics among police officers: A longitudinal test of the learning‐related predictions of the demand—control model

The present study addressed the relationships among professional efficacy, emotional exhaustion, and job characteristics (job demands and job control) in the context of a two‐wave panel study among 828 Dutch police officers. Based on the demand–control model, we expected that high demands/high control would be positively related to professional efficacy, and that high demands/low control would be related to high levels of exhaustion. Moreover, we hypothesized that high levels of exhaustion would lead to lower levels of professional efficacy and that high levels of efficacy would lead to low levels of exhaustion. Structural equation modelling largely supported these predictions. High demands were longitudinally related to high levels of efficacy and high levels of exhaustion; high control was longitudinally related to high levels of efficacy. Further, efficacy and exhaustion were indeed mutually related. Finally, high levels of exhaustion were longitudinally related to high levels of demands. We conclude that there are complex, yet theoretically, and practically interpretable relations among efficacy, strain and work characteristics.
