Does Depression Mediate the Effect of Work Organization Conditions on Job Performance?

Objective: The present study proposes to shed light on the impact of workers' depression on their work performance.

Methods: We implemented a path analyses adjusted for design effects resulting from cluster sampling using MPlus software on a sample of 1957 workers. These analyses allowed us to evaluate direct and indirect effects (mediation) while taking into account the nonindependence of observations due to cluster sampling (workers nested in their workplace).

Results: Results indicate that three indirect associations were found to be significant. Psychological demands, work schedule, and job insecurity were indirectly associated with lower levels of professional efficacy/job performance because of their positive associations with depression.

Conclusions: The results obtained suggest that interventions targeting specific work organization conditions could be warranted.
