Background Perceptions of peer drinking and alcohol expectancies have been consistently associated with alcohol use among college students. There is evidence that perceived peer drinking also shapes alcohol expectancies. Research has yet to address the potential differential impact of perceived drinking by close friends versus by typical college students on alcohol use among first-semester college students. Relatedly, mediation of these associations by specific domains of alcohol expectancies has yet to be examined.
OBJECTIVES: The first aim of the present study was to investigate whether perceptions of close friend drinking were more strongly associated with alcohol expectancies, alcohol use, and consequences of alcohol use than perceptions of typical college student drinking. The second aim focused on which alcohol expectancy domains partially accounted for the association between close friend drinking, typical college student drinking, and alcohol use and consequences.
METHOD: Participants (n = 400 first-semester college students) completed survey questionnaires, which included measures of perceived close friend/typical student alcohol use, alcohol expectancies, and drinking behaviors.
RESULTS: Results showed that close friend alcohol use was more strongly associated with alcohol use and consequences compared to typical college student use both directly and indirectly through expectancies about alcohol enhancing social behaviors.
CONCLUSIONS/Importance: These findings suggest that first-semester college student drinking is more influenced by perceived alcohol use among close friends than typical college students. Future intervention efforts for alcohol use on college campuses may benefit from including close friend network components along with targeting alcohol expectancies regarding social behaviors.
