The Job Demands–Resources model: An analysis of additive and joint effects of demands and resources

The present study investigated the additive, synergistic, and moderating effects of job demands and job resources on well-being (burnout and work engagement) and organizational outcomes, as specified by the Job Demands–Resources (JD-R) model. A survey was conducted among two Chinese samples: 625 blue collar workers and 761 health professionals. A series of multi-group structural equation modeling analyses supported the two processes proposed by the JD-R model: (1) the stress process that originates from job demands and leads, via burnout, to negative organizational outcomes (turnover intention and low organization commitment); and (2) the motivational process that originates from job resources and leads, via work engagement, to positive organizational outcomes. In contrast to moderating effects, synergistic effects of job demands and job resources on burnout and work engagement were found in both samples. However, after controlling for additive effects of job demands and job resources, these synergistic effects largely disappeared. In conclusion, the hypothesized additive effects of the JD-R model were found but the evidence for additional synergistic and moderating effects was weak.     

工作特征对工作者的影响——要求-控制模型与工作要求-资源模型的比较

工作特征是指与工作相关的因素或属性, 它对工作者的身心健康有重要影响。通过对比研究发现, 虽然要求-控制模型(Demand-Control Model, 简称DC模型)将工作特征分为相对具体的工作要求、工作控制和社会支持, 工作要求-资源模型(Job Demands-Resources Model, 简称JD-R模型)则将工作特征划分为更为概括的工作要求和工作资源两个维度, 但是它们关注的结果变量都包含个体身心健康和组织工作绩效, 都强调了工作特征对工作者的影响。在今后的研究中, 应深入探讨不同职业中起关键作用的工作特征和不同资源与要求组合的作用, 进一步研究工作特征模型对不同特点个体和我国民众群体的适用性, 并尝试将研究成果应用于工作再设计的实践, 以促进工作者的职业健康。     

Burnout and connectedness among Australian volunteers: A test of the Job Demands-Resources model

This study used the Job Demands-Resources (JD-R) model, developed in the context of occupational well-being in the paid workforce, to examine the antecedents of burnout and connectedness in the formal volunteer rural ambulance officer vocation (N = 487). Structural equation modeling using self-reports provide strong evidence for the central assumptions of the JD-R model. The findings confirm that burnout fully mediates the relationship between job demands and health problems (Hypothesis 1), and between job demands and determination to continue (Hypothesis 2). In addition, results show that connectedness fully mediates the relationship between job resources and determination to continue (Hypothesis 3). These findings have important practical implications because of the increasing problem of volunteer recruitment and retention.     

Not all job demands are equal: Differentiating job hindrances and job challenges in the Job Demands–Resources model

This study aimed to integrate the differentiation between two types of job demands, as made in previous studies, in the Job–Demands Resources (JD-R) model. Specifically, this study aimed to examine empirically whether the differentiation between job hindrances and job challenges, next to the category of job resources, accounts for the unexpected positive relationships between particular types of job demands (e.g., workload) and employees' work engagement. Results of confirmatory factor analyses supported the differentiation between the three categories of job characteristics in two samples (N ₁ = 261 and N ₂ = 441). Further, structural equation modelling confirmed the hypotheses that job hindrances associate positively with exhaustion (i.e., the main component of burnout) and negatively with vigour (i.e., the main component of work engagement). Job resources displayed the reversed pattern of relations. Job challenges were positively related to vigour. Rather unexpectedly, they were unrelated to exhaustion. Based on these findings, we discuss the importance of the differentiation between different types of job demands in the JD-R model for both theory and practice.     

Applying the job demands–resources model to the work–home interface: A study among medical residents and their partners

Work–home interference (WHI) is a prevalent problem because most employees have substantial family responsibilities on top of their work demands. The present study hypothesized that high job demands in combination with low job resources contribute to WHI. The job demands–resources (JD-R) model was used as a theoretical framework. Using a sample of 230 medical residents and their partners, our results show that the combination of high job demands (i.e., work overload, emotional and cognitive demands) and low job resources (i.e., participation in decision making, supervisory coaching, feedback, and opportunities for development) was positively related to partner ratings of the employee's WHI. When job resources were high, most job demands were not related to WHI. These findings show that the JD-R model is a conceptual framework that can be fruitfully applied to the work–family interface, adding to our understanding of which particular job designs facilitate or prevent work–home interference.     

The job demands-resources model of burnout.

The job demands-resources (JD-R) model proposes that working conditions can be categorized into 2 broad categories, job demands and job resources. that are differentially related to specific outcomes. A series of LISREL analyses using self-reports as well as observer ratings of the working conditions provided strong evidence for the JD-R model: Job demands are primarily related to the exhaustion component of burnout, whereas (lack of) job resources are primarily related to disengagement. Highly similar patterns were observed in each of 3 occupational groups: human services, industry, and transport (total N = 374). In addition, results confirmed the 2-factor structure (exhaustion and disengagement) of a new burnout instrument--the Oldenburg Burnout Inventory--and suggested that this structure is essentially invariant across occupational groups.     

Job demands–resources model in the context of recovery: Testing recovery experiences as mediators

The aim of the present study was to extend the original Job Demands–Resources (JD-R) model by taking into account recovery as an important mediation mechanism between work characteristics and well-being/ill-health. Specifically, we examined whether recovery experiences—strategies promoting recovery—might have a mediating role in the JD-R model among 527 employees from a variety of different jobs. The results showed that psychological detachment fully mediated the effects of job demands on fatigue at work and mastery partially mediated the effects of job resources on work engagement. Altogether, the results suggest that recovery merits consideration as a mediating mechanism in the JD-R model.     

Work engagement and burnout: testing the robustness of the Job Demands-Resources model

This study focuses on work engagement and its negative antipode, burnout, as well as their antecedents and consequences. According to the Job Demands-Resources (JD-R) model, two different processes have to be distinguished: a motivational process that links job resources with turnover intention through work engagement, and an energetic process that links job demands and health complaints via the mediating role of burnout. The robustness of the JD-R model was tested in a heterogeneous occupational sample (N = 846). Structural equation modeling analyses yielded a slightly modified model with only exhaustion being indicative of burnout and vigor, dedication along with absorption being indicative of engagement. The results provide evidence for the dipartite structure of the JD-R model. Multi-group analyses revealed the model to be invariant across age and gender. Although strengths of path coefficients and factor loadings differed among white- and blue-collar workers, the basic structure of the model was also confirmed among these subgroups. Therefore, the findings underscore the robustness of the JD-R model.     

工作要求-资源模型与工作倦怠的相互影响

采用间隔六个月的三波纵向设计,对国内263名企业员工的工作倦怠、工作要求、工作资源进行测量,探讨中国文化背景下企业员工工作环境的动态变化和倦怠体验的相互影响及其作用机制。研究结果表明,控制基线水平后,工作要求增量正向影响工作倦怠增量,工作资源增量负向影响工作倦怠增量;而工作倦怠增量进一步对员工所处的微工作环境产生一定的负面影响,导致工作要求进一步增加,工作资源进一步降低,因此易形成“工作环境恶化→工作倦怠加剧→工作环境进一步恶化”的恶性因果关系回路。     

The role of personal resources in explaining well-being and performance: A study among young veterinary professionals

This study examines the role of three personal resources (i.e., proactive behaviour, reflective behaviour, and self-efficacy) in the Job Demands–Resources (JD-R) model in order to predict self and other ratings of performance. The sample consisted of 860 Dutch veterinary professionals and 170 colleagues. We hypothesized and found that work engagement mediates the relationship between job as well as personal resources and extrarole performance and the relationship between job resources and work engagement. Although hypothesized, we found no support for the mediating role of exhaustion in the relationship between job demands as well as personal resources and inrole performance. Moreover personal resources were directly related to in- and extrarole performance. In conclusion, the study expands the JD-R model by integrating personal resources at a behavioural level and performance measures in the model, and shows that personal resources have a mediating and initiating role in explaining work engagement and performance in young veterinary professionals.

Weekly work engagement and flourishing: The role of hindrance and challenge job demands

Two studies were conducted to examine how home healthcare nurses stay engaged in their work and maintain their psychological well-being. In Study 1, we hypothesized that nurses would perceive work pressure more as a hindrance demand than as a challenge demand, and that the reverse would be true for emotional demands. We approached 120 home healthcare nurses who filled in a survey. Results of a series of paired sample t-tests supported our hypotheses. In Study 2, we used the JD-R model to hypothesize that weekly job demands can either facilitate or undermine the positive impact of personal resources on work engagement and flourishing, depending on the nature of the job demand (hindrance vs. challenge). A sample of 63 nurses filled in a questionnaire at the end of the working week during three consecutive weeks (N = 3 × 63 = 189 occasions). Results of hierarchical linear modeling showed that emotional job demands strengthened the effect of personal resources on weekly well-being, whereas work pressure undermined this effect. Taken together, the present findings challenge the idea that whether job demands act as hindrances or challenges is the same for all occupations and for all individuals.     

The role of workaholism in the job demands-resources model

Background and Objectives: The present study tries to gain more insight in workaholism by investigating its antecedents and consequences using the job demands-resources model. Design: We hypothesized that job demands would be positively related to workaholism, particularly when job resources are low. In addition, we hypothesized that workaholism would be positively related to negative outcomes in three important life domains: health, family, and work. Methods: The research involved 617 Italian workers (employees and self-employed). To test the hypotheses we applied structural equation modeling (SEM) and moderated structural equation modeling (MSEM) using Mplus 6. Results: The results of SEM showed a good model where workload, cognitive demands, emotional demands, and customer-related social stressors were positively related to workaholism and work–family conflict (WFC) (partial mediation). Additionally, workaholism was indirectly related to exhaustion and intentions to change jobs through WFC. Moreover, MSEM analyses confirmed that job resources (job security and opportunities for development) buffered the relationship between job demands and workaholism. Particularly, the interaction effects were statistically significant in five out of eight combinations. Conclusions: These findings suggest that workaholism is a function of a suboptimal work environment and predicts unfavorable employee outcomes. We discuss the theoretical and practical implications of these findings.     

The determinants of employee absenteeism: An empirical test of a causal model*

LISREL estimates of the parameters of a causal model of absenteeism are reported for a sample of 425 full-time employees of a 327-bed medical centre. The model modifies and extends the conceptual framework of Steers & Rhodes (1978) and includes routinization, centralization, pay, distributive justice, work involvement, role ambiguity, conflict and overload, kinship responsibility, organizational permissiveness, job satisfaction, job involvement, organizational commitment, health status and alcohol involvement as the determinants of absenteeism. Based on self-report measures of absence frequency, significant positive direct effects of kinship responsibility, organizational permissiveness, role ambiguity and alcohol involvement, and negative direct effects of centralization, pay and job satisfaction yielded an R² for absenteeism of 21.6. Job satisfaction completely mediated the effects of routinization and work involvement, and partially mediated the effects of centralization and role ambiguity.

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.     

Antecedents and Consequences of Job Stressors: A Study in a Third World Setting

The present study investigates the antecedents and consequences of job stressors, especially role conflict and role ambiguity, in an environment where multiculturalism is a dominant feature of the workforce. This study used a sample of 397 employees in various manufacturing and service organizations in the United Arab Emirates (UAE). Path analysis revealed that age is negatively related to role conflict and positively to role ambiguity, and that nationality is positively related to role ambiguity. Results further indicate that role conflict directly and negatively influences job satisfaction, whereas role ambiguity directly and indirectly influences job satisfaction. Role conflict (directly), role ambiguity (directly and indirectly) and positively influence absenteeism. Both role conflict and role ambiguity negatively influence affective and behavioral tendency dimensions of attitudes toward organizational change, while role ambiguity directly and negatively influences cognitive attitude toward organizational change. Implications, limitations, lines of future research, and contributions were discussed.     

The longitudinal impact of a job crafting intervention

This study examined the impact of a job crafting intervention based on job demands-resources (JD-R) theory. We hypothesized that the intervention would influence participants’ job crafting behaviours, as well as their job demands, job resources, and personal resources. In addition, we hypothesized a positive impact of the intervention on work engagement and self-rated job performance. The study used a quasi-experimental design with a control group. Teachers (N = 75) participated in the job crafting intervention on three occasions with 9 weeks in-between the first and second measurement, and 1 year in-between the second and third measurement. Results showed that the intervention had a significant impact on participants’ job crafting behaviours, both at time 2 and time 3. In addition, the results showed a significant increase of performance feedback, opportunities for professional development, self-efficacy, and job performance 1 year after the job crafting intervention. Participants’ levels of job demands, resilience, and work engagement did not change. We discuss the implications of these findings for JD-R theory and practice.     

Job crafting and job performance: A longitudinal study

In this three-wave study (N = 288), we examined whether job crafting intentions and work engagement led to actual job crafting behaviours and, in turn, to higher levels of prospective work engagement and job performance. We used the Job Demands-Resources model as a theoretical framework and defined job crafting as the self-initiated changes that employees make in their job demands and resources. One month after reporting their job crafting intentions, respondents rated their actual job crafting behaviours. Again one month later, they rated their levels of work engagement, in-role performance, and organizational citizenship behaviour towards individuals (OCBI). Results of structural equation modelling showed that job crafting intentions and work engagement significantly related to actual job crafting, which, in turn, related to higher levels of work engagement, while controlling for job characteristics. Results further showed that engaged employees performed better on their in-role tasks but did not perform more OCBIs. The findings suggest that employees can increase their own work engagement and job performance through job crafting.
