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

TLDR

The study aimed to empirically test whether distinguishing job hindrances and job challenges, alongside job resources, explains the unexpected positive links between certain job demands (e.g., workload) and work engagement within the JD‑R model. Confirmatory factor analyses and structural equation modeling across two samples confirmed that job hindrances predict higher exhaustion and lower vigor, job resources show the opposite pattern, and job challenges increase vigor but are unrelated to exhaustion, underscoring the value of differentiating demand types.

Abstract

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.
