There is a need to identify students at risk for suicide. Predictors of suicidality were examined separately for men and women in a college health survey of 630 students. Women reported higher levels of suicidal ideation than men in the previous year. Separate regression analyses for men and women accounted for significant amounts of the variance in suicidal ideation, 25% for men and 26% for women. Both men and women shared frequency of depression and hopelessness in the previous year as predictors of suicidal ideation but gender specific predictors also emerged. Chronic recent alcohol consumption and reports of sexual assault were important predictors of suicidal ideation for women, while reports of having been physically assaulted were uniquely reported as predictors of suicidal ideation for men. Reports of being in a fight were significantly associated with suicidal ideation for the entire sample. Reports of prior suicide attempts were predicted for the whole sample by recent alcohol use and depression in the previous year. Future research should focus on gender specific predictors of college student suicide. Therapist assessments of suicidality should be driven by gender specific risks as well as by shared risk factors such as hopelessness. (Contains 2 tables.)
