Neurocognitive and Neurobehavioral Mechanisms of Change Following Psychological Treatment for Alcohol Use Disorder

The CBT condition will include 8 weekly, 60-minute sessions, and will be delivered according to the Epstein \& McCrady (2009) cognitive-behavioral treatment manual, excluding material provided in the platform treatment. The treatment manual and accompanying client workbook provide detailed therapist instructions for each session, client exercises, worksheets, and homework assignments. The treatment focuses on cognitive and behavioral coping skills training, and emphasizes problem-solving as an overall approach to dealing with drinking. Treatment sessions may be audio-recorded for supervision and to ensure that the treatment is being delivered as intended.

The MBT condition will be adapted from the 8-week version of the mindfulness-based relapse prevention (MBRP) manual (Bowen et al., 2011; Witkiewitz et al., 2005). The main adaptation will be to eliminate the relapse prevention/CBT components and focus attention on mindfulness practices. The mindfulness practices in MBT are designed to increase awareness of triggers and decrease reactivity to distress or discomfort in the presence of triggers (Witkiewitz \& Bowen, 2010). The relevant worksheets and homework assignments focusing on mindfulness tools will be maintained from the MBRP manual. Treatment sessions may be audio-recorded for supervision and to ensure that the treatment is being delivered as intended.
