Comparison of the Effectiveness of Dialectical Behavior Therapy and CompassionFocused Therapy on Blood Cortisol and Serotonin Levels in Drug Abusers

Abstract Background: This study aimed at comparing the efficacy of dialectical behavioral therapy and compassionate focused therapy on blood cortisol and serotonin levels among drug abusers. Materials: It was a quasi-experimental study with pretest-posttest design and control group. The statistical population consisted of all men with drug abuse referring to Torbat-e-Heydariyeh Adult Drug Abuse Clinic in 2018, 60 of whom were selected by simple random sampling for two experimental groups (DBT, CFT) and a control group. The experimental group was trained for 10 90-min sessions, but the control group was on the waiting list and received no training. Demographic questionnaire and in vitro serum levels of cortisol and serotonin were used for data collection before and after the intervention. Data were analyzed using multivariate analysis of covariance (MANCOVA) in spss 24 software. Results: The results of multivariate analysis of covariance showed that in the two groups of dialectical and compassionate-focused behavioral therapy, intervention on self-control and blood cortisol had a significant effect on post-test (p
