Abstract
The current study examined the effects of social anxiety, depressive symptoms, and alcohol expectancies of social behavior change on alcohol involvement to determine whether the self-medication and/or social learning models predicted drinking behavior in a sample of over 400 eighth grade students. Middle school students completed confidential surveys that assessed current alcohol use and expectancies as well as negative affectivity including social anxiety and depressive symptoms. Consistent with the self-medication hypothesis, depressive symptoms predicted more frequent and heavier alcohol use as well as solitary drinking. The social learning model was supported by a negative association between social anxiety and quantity/frequency of drinking and less drinking at parties, and a positive association between alcohol expectancies and all drinking outcomes. Additionally, social anxiety moderated the association between expectancies and alcohol use. These findings suggest that self-medication and social learning processes may both play a role in predicting early adolescent alcohol use and the contexts in which youths drink.
