The relationship between binge drinking and prosocial bystander behavior among college men

Abstract

Objectives: This study prospectively examined binge drinking’s effect on prosocial bystander behavior and indicators of bystander behavior: intentions to intervene, self-efficacy to intervene, and positive outcome expectancies for intervening. Participants: College men were recruited from February to April 2010. Methods: Pre- and posttest surveys were administered as part of a randomized controlled trial (n?=?743). Potential confounders were identified using Pearson product-moment correlations. Controlling for covariates, multiple linear regression was used to examine whether binge drinking was predictive of prosocial bystander behavior and indicators of bystander behavior. Results: Binge drinking was related to lower bystander behavior (p<.05), lower intentions to intervene (p<.001), and less positive outcome expectancies for intervening (p<.05). Conclusions: Binge drinking may reduce the ability to notice a risk situation and intervene as a prosocial bystander. Results highlight the need for bystander programs to address alcohol use within the context of bystander behavior.
