The authors aimed to integrate the differentiation between two types of job demands in the Job-Demands Resources (JD-R) model. Specifically, this study examined whether the differentiation between job hindrances and job challenges, next to the category of job resources, accounts for the 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 (N1 = 261 and N2 = 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, the authors discuss the importance of the differentiation between different types of job demands in the JD-R model for both theory and practice.
