College students’ alcohol expectancies and sexual assault bystander behavior

College students, alcohol, sexual assault


Many college sexual assault prevention efforts have focused on the bystander approach. While
most sexual assaults among students occur within the context of alcohol, no studies have examined the
impact of alcohol-related factors on bystander behavior. This exploratory study assessed relationships
between students’ alcohol expectancies and the likelihood of intervening in a potential sexual assault.
Students(n=220) completed an online survey. Linear regressions were performed. Among men, greater
overall expectancy scores(Stnd.ß=0.375,p=.008) and greater sociability scores(Stnd.ß=0.354,p=.012)
were related to greater likelihood of action. Among women, greater self-perception scores were related to
less likelihood of action(Stnd.ß=-0.215,p=.010). Explanations for differences between sexes are explored.
