A Pilot Randomized Controlled Trial of Dialectical Behavior Therapy (DBT) for Craving and Cessation in Marijuana Use Disorder Patients: Feasibility, Acceptability, and Appropriateness

Abstract Purpose: This study has investigated the feasibility and preliminary efficacy of DBT for Marijuana cessation and craving reduction as a pilot RCT.Methods: Sixty-one participants were randomly assigned to one of the DBT or psycho-education as active control-group with two-month follow-up. Patients completed measures at pre-interventions, post-interventions, and a two-month follow-up.Results: feasibility in DBT is significantly higher than the control group. In the DBT group 29/30 (96% retention) and in control group 24/31 (77% retention) completed all sessions (χ2= 4.95, p = 0.02). Moreover, 29/30 (96%) in the DBT group and 20/31 (64.5%) in the control group completed the two-month follow-up (χ2= 9.97, p = 0.002). For the acceptability of the intervention, results showed 16.57 (agree) in DBT and 9.6 (neither agree nor disagree) in control groups for p < 0.05. For appropriateness, results showed 17.03 (completely agree) in DBT and 10.7 (neither agree nor disagree) in control-groups for p 0.05); however, in “emotionality,” subscale DBT showed a significant reduction rather than the control group (F = 19.94, p < 0.05). For cessation rates, DBT was compared with the control group at the posttest (46% vs. 16%) and follow-up (40% vs. 9.5%), and results proved higher effectiveness in the DBT group for p < 0.05. Furthermore, among those who have lapsed, participation in the DBT group had fewer days than consume for p <0.05.Conclusions: DBT shows feasibility, acceptability, and promise in improving cessation rate in Marijuana use disorder and warrants further investigations.
