Testing Mindfulness-Based Relapse Prevention with Medications for Opioid Use Disorder Among Adults in Outpatient Therapy: a Quasi-experimental Study

Abstract

Objectives: This study aimed to explore the effectiveness of mindfulness-based relapse prevention (MBRP) with individuals receiving medication for opioid use disorder (MOUD) in a naturalistic, open-ended outpatient group treatment setting. Methods: Eighty participants (mean age 36.3) who had at least 90 consecutive days substance free self-selected into treatment (MBRP, n = 35) or comparison groups (treatment as usual, TAU, n = 45). Outcomes tracked included treatment retention and relapse, and self-reported craving, anxiety, depression, and mindfulness at baseline, 12 weeks, 24 weeks, and 36 weeks post-recruitment. MBRP group participants attended biweekly 60-min sessions for 24 weeks. A linear mixed model analysis of variance determined the significance of the MBRP intervention on changes in craving, anxiety, depression, and mindfulness. Results: No significant differences in sex, education level, insurance status, relationship status, or employment status were detected at baseline between groups. The 36-week retention (74%, MBRP/MOUD; 71%, TAU/MOUD) and relapse rates (43%, MBRP/MOUD; 47%, TAU/MOUD) were similar for the groups. There were only four relapses on opioids. Significant reductions (p
