Affective factors explaining the association between depressive functioning and alcohol outcomes among college students

Abstract

Rates of co-occurring depression and alcohol use are higher among college students than in the general population. Further research is needed to illuminate how the mechanisms with which individuals process negative emotions may clarify the link between depressive symptoms and drinking. Objective: To assess how three potential mediators representing affective functioning (ie, need for affect, distress tolerance, emotion regulation) explain the relationship between depressive symptoms and alcohol use (ie, quantity and problems). Participants: The sample consisted of 227 college student heavy drinkers. Methods: Participants completed computerized self-report surveys in Fall 2016. Results: Path analyses revealed need for affect mediated the association between depressive symptoms and alcohol quantity, while emotion regulation mediated the relationship between depressive symptoms and alcohol-related problems. Conclusions: Findings highlight the importance of various affective functioning mechanisms to the depressive symptom-drinking link. Future research could target these mechanisms in college interventions for co-occurring mood symptoms and alcohol use.
