Research has established that student-athletes drink more alcohol and experience greater consequences compared to their non-athlete peers, prompting many investigators to consider university athletes an "at risk" subpopulation of college students. However, a dearth of research exists on explaining drinking behavior among student-athletes in general, and among team leaders compared to nonleaders in particular. This article responds to calls in the literature for more explanatory research assessing differences in alcohol use between team members and team leaders. Specifically, the aim of this study was to investigate, in a multivariate assessment, the ability of normative beliefs, perceptions of risk, coaches' attitudes toward drinking, and socio-demographic variables to discriminate among four groups of student athletes classified across levels of drinking intensity and leadership status. An anonymous survey was administered to 211 student-athletes at a mid-size, southeastern university. Results indicated substantial drinking behavior among this group. A multiple discriminant function analysis revealed that student-athletes who were non-leaders and engaged in heavy, episodic drinking perceived greater risks associated with alcohol consumption, greater leniency from coaches, and greater levels of alcohol use among peers. Implications for university interventions are discussed. (Contains 3 tables.)
