The mediating role of psychophysic strain in the relationship between workaholism, job performance, and sickness absence: a longitudinal study.

ABSTRACT

OBJECTIVE: To test a theoretical model in which workaholism predicts both directly and indirectly, via psychophysic strain, job performance and sickness absences. METHODS: A multimethod study was performed examining a sample of 322 workers in a private company. The study was articulated into two phases, over a time period of 15 months. Workaholism was assessed using a self-report measure (time 1). Psychophysic strain was measured by the occupational physician, performance by the supervisor, and data on sickness absences were collected from the company's database (time 2). RESULTS: Results highlighted a positive relationship between workaholism and psychophysic strain. Psychophysic strain was negatively associated with job performance and positively associated with sickness absences. In addition, workaholism predicted sickness absences. CONCLUSION: Workaholism negatively affects the health of workers. This is associated with lower working performance and greater sickness absences.
