Abstract
Suicidal ideation (SI) is common among college students. Trait impulsivity (i.e., negative urgency, lack of premeditation, lack of perseverance, sensation seeking, positive urgency) and alcohol use/problems may serve as developmentally and contextually relevant risk factors of SI among college students. This study examined alcohol use/problems as a moderator of the associations between five impulsivity traits and SI, hypothesizing that alcohol use/problems would interact with negative urgency, lack of premeditation, and sensation seeking to increase the likelihood of SI. A sample of 931 undergraduate students completed an online survey, and a moderation analysis was conducted in Mplus. Alcohol use/problems significantly interacted with sensation seeking to increase one’s likelihood of SI (β=0.16, p<.05). There was a main effect of negative urgency on SI such that negative urgency increased the likelihood regardless of alcohol use/problems (β=0.28, p<.001). There was a main effect of positive urgency on SI such that positive urgency decreased the likelihood regardless of alcohol use/problems (β=-0.15, p<.01). These findings should be considered in light of limitations (e.g., homogenous sample, cross-sectional design). Despite limitations, these findings carry important implications for future directions for research and clinical interventions related to suicide, alcohol use/problems, and impulsivity among college students.
