THE ROLE OF ALCOHOL-RELATED EXPECTANCIES IN THE PREDICTION OF DRINKING BEHAVIOR IN A SIMULATED SOCIAL-INTERACTION

This study investigated the relationship between socially-relevant alcohol-related beliefs and drinking behaviour in a laboratory-based study. Ninety male subjects were told they would be videotaped while completing the Simulated Social Interaction Test; they were then assigned to one of three conditions. In the first, alcohol consumption prior to the interaction was optional, in the second, a standard dose was administered, and in the third, no alcohol was offered ne outcome measures included drinking behaviour and rated level of social skill. In the optional condition, beliefs that alcohol would reduce anxiety in social situations and enhance social competence predicted amount consumed. The decision to continue drinking after the compulsory dose was predicted by anxiety level. In the no alcohol condition, rated social skill was negatively correlated with the beliefs that alcohol reduces tension and reduces fear of negative evaluation. Results are discussed with reference to social learning approaches to understanding drinking behaviour.
