Abstract

The present study sought to determine whether the co-occurrence of problem drinking heightens suicide risk in individuals with depression in Japan, using a sample of 784 outpatients (287 men and 497 women) with depressive disorder. Female subjects with at least a moderate problem drinking showed significantly more severe depression and suicidality than those without, but no such difference was identified in men.
