Research indicates that social influences impact college alcohol consumption. However, little work has addressed how selection processes may serve as an influential factor predicting alcohol use in this population. A model of influence and selection processes contributing to alcohol use across the transition to college was examined using structural equation modeling among a sample of late adolescents (N=193). Results indicate selection processes occur as students transition into college and have the opportunity to seek out and join new friend circles, while peer influence occurs once students have settled within a circle of friends at college. Implications for prevention are discussed.
