Introduction: The present study aimed to compare the effectiveness of group schema therapy and group-based acceptance and commitment therapy on emotion regulation strategies in substance abusers. Materials and Methods: The statistical population of this study was all men with substance abuse in Mashhad city in 2018. The samples included 60 substance abusers who were selected purposefully and assigned into 3 groups including schema therapy, acceptance and commitment therapy and control.

All participants completed emotion regulation questionnaire (Gratz and Roemer, 2004) in pretest, posttest and 3-months follow up. Data analyzed through descriptive statistics, Kolmogrov-Smirnov test, covariance analysis, and SPSS software. Results: The results showed that both experimental groups had a significant reduction in maladaptive strategies of emotional regulation and increase in adaptive strategies compared to the control group. The difference between the three groups was significant in the post-test phase (F= 8.119; P<0.001) and 3-month follow-up (F= 0.907; P<0.002). Conclusion: It seems that schema therapy is more effective than acceptance and commitment therapy to reduce maladaptive strategies of emotional regulation in substance abusers.
