Abstract
Depression in the workplace is prevalent and can result in substantial negative effects. Many studies have documented the association between trait hostility and depressive symptoms. It has been demonstrated that resilience modulates the association between trauma or life event, and depression. The aim of this study was to investigate the effect of the interaction among resilience, trait hostility, and life events on depressive symptoms in company workers. Participants were 575 Japanese workers at three worksites. Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression (CES-D) scale, trait hostility with Buss-Perry Aggression Questionnaire (BPAQ), resilience with the 14-item Resilience Scale (RS-14) and whether participants had experienced life events within the past month. Regression analyses were conducted to investigate the interaction of hostility, resilience, and life events on depression. Post hoc analysis using the Johnson-Neyman technique were conducted. Regression analysis showed that the model was significant: R2 = 0. .470, F(7, 567) =44.5, p 85.1). and that that there were no significant association between life event and depressive symptoms (RS-14 > 75.9). The results of this study suggest that an association between trait hostility and depressive symptoms and an association between life event and depressive symptoms, depended on resilience.
