| Abstrakt: | Background: Although poor sleep quality is the most common subjective complaint of workers and is a risk factor for depressive symptoms and suicide, researchers have not yet provided definitive links between insomnia symptoms, depressive symptoms, and suicide. Purpose: In our mediation model, we hypothesized relationships among insomnia symptoms, depressive symptoms, and suicide ideation. The purpose here was to use structural equation modeling (SEM) to test our mediation model. Method: Three hundred forty-three Japanese full-time white-collar workers completed the measures to assess insomnia symptoms, depressive symptoms, and suicide ideation over an approximately 3-month period. Results: A SEM analysis revealed that insomnia symptoms were positively and significantly associated with depressive symptoms, and depressive symptoms were positively and significantly associated with suicide ideation. Two tests showed a significant indirect effect of insomnia symptoms on suicide ideation through depressive symptoms. Thus, these results supported our mediation model. Conclusion: We conclude that insomnia symptoms were positively associated with suicidal ideation, though this relation was accounted for by depressive symptoms in Japanese white-collar workers.
