A second well-researched approach to couple-involved therapy is behavioral couples therapy (BCT) for AUD and other SUD.31 BCT is a 12- to 20-session intervention that lasts 3 to 6 months. The core components of BCT include (a) a daily “recovery contract” to encourage abstinence from substance use, (b) interventions to increase positive couple behaviors, and (c) training in behavioral communication skills. Participants with SUD also complete weekly urine drug screens, and progress is monitored in a calendar-assisted approach (similar to the Timeline Follow-Back procedure).32
