Evaluation of a treatment-appropriate cognitive intervention for challenging alcohol outcome expectancies

The current study evaluated an alcohol expectancy challenge (EC) that did not require alcohol administration and could therefore be implemented in a treatment setting. Participants in the treatment group directly challenged alcohol expectancies endorsed on an expectancy questionnaire. A total of 62 male and female undergraduates completed the study (32 control participants, 30 EC participants). Self-report questionnaires were collected pre- and post-intervention, and alcohol logs were kept during the study. The EC resulted in significant reductions in alcohol expectancies across multiple expectancy dimensions. Although the analysis for alcohol consumption was not significant, there was a trend toward better outcomes for male participants in the EC condition. In contrast to study hypotheses, women in the EC condition increased their alcohol consumption from pre to post-test to a greater degree than did control participants.
