This single-arm pilot study will recruit participants with moderate to severe alcohol use disorder for a 4-week virtual intensive outpatient program (IOP). The program aims to replicate the structure and abstinence monitoring of a residential treatment program although the program is delivered entirely virtually.

This pragmatic single-arm pilot study will recruit participants with moderate to severe alcohol use disorder who are seeking abstinence for a virtual intensive outpatient program (virtual IOP) The IOP will take place primarily over a 4 week period. Components of the program include a cognitive behavioral therapy for alcohol use disorder group (12 sessions), a DBT skills group (12 sessions), a Health and Wellness group (8 sessions), weekly individual therapy, weekly medication management appointments, and abstinence monitoring multiple times per day using breathalyzers equipped with facial recognition and internet connectivity. Following completion of the program, participants will complete an on-site end of treatment visit and two follow up visits at approximately day 30 and day 60 following termination of the virtual IOP. Participants will be offered the opportunity to participate in an optional weekly aftercare group for approximately 2 months after completion of the virtual IOP. Interested participants will also be able to complete optional follow-up sessions every 2 months for an additional 10 months following the end of the 60-day follow-up session.
