Web-Based Treatment of Heavy Drinking Among Women With a History of Sexual Trauma

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to empirically evaluate a web-based intervention to reduce heavy drinking among college women with a history of sexual assault who display elevated levels of psychological distress. College women with a history of sexual assault often report more heavy drinking and psychological distress than women without a history of assault. Moreover, women with assault histories often have difficulty regulating their emotions and tolerating distress which can lead to a pattern of drinking to cope distress. Trauma exposure, negative mood, and poor coping strategies have been associated with poor treatment outcomes and relapse following alcohol treatment. Incorporating distress tolerance and emotion regulation skills with an alcohol intervention may enhance treatment effects among women with a history of sexual assault by decreasing their motivation to drink to cope with depression or anxiety and by building adaptive coping strategies. Therefore, the web-based intervention will include cognitive behavioral skills for reducing alcohol consumption and incorporate emotion regulation and distress tolerance skills from Dialectical Behavior Therapy.

Detailed Description
-----------------
For the small randomized controlled trial, heavy drinking college women with a history of sexual assault will be recruited and randomized to receive the intervention or an assessment only control. Online surveys will be administered at baseline, and post-treatment as well as 1-month and 6-months post-treatment.
