Ultrabrief Behavioral Activation for Reducing Alcohol Use

This is a pilot study to assess feasibility, acceptability, and preliminary efficacy of a single-session ("ultrabrief") psychological intervention to reduce alcohol use in participants with mild to moderate alcohol use disorder (AUD). The intervention is a condensed form of the Life Enhancement Treatment for Substance Use (LETS ACT), behavioral activation (BA) for co-morbid depression and substance use. The investigators hypothesize that UBA is feasible and acceptable. The investigators hypothesize that UBA will reduce overall total alcohol consumption as determined by self-report measures capturing drinking behavior for the 3 months prior to treatment versus the 3 months after treatment when compared to an "assessment only" condition.
