The experimental group received dialectical behavior therapy-based skill training in 12 sessions of 120 min. The emotional regulation, social avoidance and distress were investigated at both groups. Data were analyzed using SPSS-22 software through a covariance analysis. Results: The mean of age of the subjects was 12.93±3.20 years and 13.00±3.10 years in experimental and control groups, respectively. Following the balanced pre-test scores, the results showed that dialectical behavior therapy could decrease social anxiety disorder (P<0.0001) and negative emotional regulation (P<0.0001 ) in adolescents with social anxiety disorder in post-compared to pre-test, while, no significant difference was found between groups for pre-test and post-test in control group (P>0.05).
