Social norms approaches to understanding problematic alcohol use have become popular on college campuses. Failure to understand the campus norms may lead to ineffective interventions and possibly increased alcohol use. A randomly drawn sample of 2.487 students from a western university where the nonnative use of alcohol is low was invited to participate in an on-line study of drinking norms, religiosity, and rebelliousness. Of those invited, 585 students submitted valid questionnaires. Results suggest that normative beliefs about friends' alcohol use are predictive of personal use. Additionally, normative beliefs about alcohol use by the average student were not predictive of personal use. Religiosity was found to be a protective factor. Tendencies to rebel were predictive of increased alcohol use. The findings suggest that interventions should target normative groups that students who drink identify with. Also, the promotion of those facets of religion that promote social identification may reduce problematic alcohol use.
