The purpose of this study is to develop and test a new brief intervention to reduce heavy drinking and social anxiety in college drinkers.

Episodic alcohol abuse is common among college students. Recently, brief interventions focusing on motivational strategies and behavior skills to reduce heavy drinking and alcohol-related problems have shown beneficial small to medium effects in college drinkers who reported heavy drinking and/or alcohol-related problems. Most interventions have not taken into account psychiatric comorbidity, in particular social anxiety, a frequent problem for college students that has been linked to excessive alcohol use. This project will extend knowledge on brief interventions by integrating cognitive-behavioral therapeutic strategies for social anxiety with an existing alcohol intervention designed for college students.

The efficacy of a new integrated treatment, the Brief Intervention for Socially Anxious Drinkers (BISAD) was developed and tested. All participants reported heavy alcohol use, alcohol-related problems and social anxiety based on standardized measures. Phase I of the study focused on the development of the treatment manuals and measures of therapy integrity for BISAD and an alcohol-focused intervention, a modified treatment-as-usual at the local university. During this phase therapists were trained to administer the manualized interventions to study participants (N=12). Phase II included further refinement of the therapy integrity measures and data collection for the pilot study (N=41). Participants were randomized to either BISAD (n=21) or a modified treatment-as-usual (n=20) condition. The pilot study provide preliminary data on the efficacy of the proposed intervention in reducing heavy drinking, social anxiety, and their negative consequences at 1-month and 4-month follow-ups after treatment termination. These data provide estimated effect sizes for future testing of BISAD in a full-scale clinical trial. Furthermore, the study results contribute to the conceptualization and methodological development of combined interventions for other substance use and psychiatric problems.
