Introduction: The purpose of the study was to compare the effectiveness of group interpersonal therapy and group cognitive behavioral therapy to reduce the depression symptoms of the patient with social anxiety disorder. Method: It is an experimental research with pretest and posttest. The participants were female students who suffered from social anxiety disorder. 40 students were selected and then randomly divided into two CBT and ICP groups. The research tools were Social Phobia Inventory (SPIN), Beck Depression Inventory-II (BDI-II) and Structural Clinical Interview for DSM-IV (SCID). Data were analyzed by Multivariate Covariate Analysis. Results: Data analysis indicated that there's a significant relationship between group interpersonal therapy and group cognitive behavioral therapy in reducing the depression of social phobic patients. In a way that the efficacy of group interpersonal therapy on depression reduction (f= 16.2, p= 0.001) and social phobia symptoms (f= 12.4, p= 0.002) is more than group cognitive behavioral therapy. Discussion and Conclusion: Findings indicate that group interpersonal therapy is more effective in reducing depression symptoms and social phobia than group cognitive behavioral therapy; thus, group interpersonal therapy is considered as the preferred psychotherapeutic treatment for social anxiety disorder especially in the presence of co-morbid condition.
