Examining psychometric properties of distress tolerance and its moderation of mindfulness-based relapse prevention effects on alcohol and other drug use outcomes

► We examined whether distress tolerance moderated treatment effects on AOD outcomes. ► Clients with lower distress tolerance receiving MBRP vs. TAU had fewer AOD use days. ► A plateau effect suggests that effects were not maintained at the 4-month follow-up. ► Distress tolerance is a characteristic to consider in matching clients to aftercare. ► MBRP may be particularly helpful for individuals with lower distress tolerance.
