The mediating role of frustration of psychological needs in the relationship between job insecurity and work-related well-being

This study aims to test a new process underlying the negative relationship between job insecurity and work-related well-being. Specifically, based on Self-Determination Theory, frustration of the psychological needs for autonomy, belongingness and competence was expected to explain the associations between job insecurity and emotional exhaustion and vigour (i.e. the core energy-related components of burnout and work engagement, respectively). Structural equation modelling using data from a heterogeneous sample of 3185 Flemish employees confirmed that frustration of the three needs mediated the association between job insecurity and both outcomes. These results suggest that job insecurity is related to impaired work-related well-being, because it frustrates employees' psychological needs. This study contributes to a rather small, but growing body of research on the theoretical explanations of the negative consequences of job insecurity for employees' work-related well-being.
