Projection, conformity and deviance regulation: a prospective study of alcohol use.

We examine how alcohol-related attitudes and behaviour are related to injunctive and descriptive norms over time, and how these perceptions are linked to the experience of alcohol-related problems. In a longitudinal study of alcohol use (n=239, over three time points), we explored the presence of projection, conformity and deviance in college students--a group in the process of identity formation and redefining peer relationships. We found that the first year of college was characterised by both conformity and projection, and that positive attitudes towards alcohol, greater drinking, and higher descriptive norms were associated prospectively with more alcohol-related problems. However, in the second year, the pattern changed such that alcohol consumption behaviour was characterised by deviance such that those who believed others engaged in more drinking reported relatively lower consumption. The longitudinal findings support deviance regulation theory (Blanton, H., & Christie, C. (2003). Deviance regulation: A theory of action and identity. Review of General Psychology, 7, 115-149), which states that individuals form identities by deviating from peers in ways they perceive as desirable. In general, one must consider the role and stage of identity development when making predictions about how attitudes and perceived norms influence alcohol use and the experience of alcohol-related problems.
