OBJECTIVE: Poor sleep quality exacerbates suicidal ideation. Depression, anxiety, and stress may play important roles in this relationship. However, the underlying mechanisms remain unknown.
METHOD: A total of 2,598 young men were recruited for a cross-sectional study focusing on a range of sociodemographic factors, emotions, sleep quality, and suicidal ideation. Parallel, serial, and moderated mediation models were used to determine whether depression, anxiety, and stress mediated the relationship between poor sleep quality and suicidal ideation.
RESULTS: Direct and indirect effects of poor sleep quality on suicidal ideation were observed. Depression, anxiety, and stress mediated the relationship between poor sleep quality and suicidal ideation (βDepression = 0.166, 95% confidence interval [CI]: 0.144, 0191; βAnxiety = 0.153, 95% CI: 0.130, 0.177; βStress = 0.176, 95% CI: 0.154, 0.200). The serial mediation model indicated that depressive and stress symptoms co-play a serial mediating role in the relationship between poor sleep quality and suicidal ideation (βa = 0.049, 95% CI: 0.036, 0.062; βb = 0.099, 95% CI: 0.080, 0.120). The moderated mediation model revealed that the mediating role of stress on the relationship between poor sleep quality and suicidal ideation was moderated by depression (β = 0.173, 95% CI: 0.150, 0.197). Self-reported measures and the study's cross-sectional design preclude the causal inferences reported.
CONCLUSIONS: The findings of this study prompt clinical and scientific researchers to consider the interplay among affective disorders when investigating etiological and psychological factors that may contribute to suicidal ideation.
