Research indicates that social influences impact college students' alcohol consumption; however, how selection processes may serve as an influential factor predicting alcohol use in this population has not been widely addressed. 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 with 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 of alcohol abuse are discussed. (Contains 1 table and 2 figures.)
