Suicidal ideation and behavior among college students are serious and prevalent problems that warrant considerable attention. While a variety of situational and personality factors have been linked to suicidal behavior, alcohol use is one of the most commonly cited factors. As alcohol consumption is a frequent activity for many college students, the association between alcohol use and suicidal behavior may have particularly lethal consequences for students. Yet, to date, few studies have examined the relationship between drinking and suicidal ideation and behavior in this population. This study provides empirical support for this relationship. That is, significant relationships were found between past alcohol use and past suicide attempt(s) and between past binge drinking and past suicidal behavior and ideation. The results are discussed in light of their implications for intervention with and assessment of students presenting with suicidal ideation, behavior, and/or binge drinking.
