Objective: The purpose of this study was to investigate the effectiveness of transdiagnostic treatment on experiential avoidance, cognitive emotion regulation in patients with obsessive-compulsive disorder and its comparison with exposure and prevention response therapy
Method: The present study is a pre-test and post-test semi experimental design. The study population in this study was all obsessive compulsive patients referring to Qazvin psychological services centers in 2018. 40 patients were selected by purposeful sampling method and randomly assigned to 2 groups of 20 (the first group was treated with transdiagnostic treatment and the second group was treated with ERP). In this study, variables such as age and sex were controlled. The tools used in the present study were: Yale Brown Obsessive Compulsory Inventory (YBOCS), Structured Clinical Interview (SCID-I), Obsessive-Compulsive Questionnaire, , Multidimensional Experiential Avoidance QuestionnairQ( and cognitive emotional regulation questionnaire (CERQ). The collected data were analyzed by SPSS software and with using covariance analysis and paired t-test.
Results: The results showed that transdiagnostic treatment significantly decreased experiential avoidance and also improved, cognitive emotion regulation, in patients with OCD (p <0.001). On the other hand, the effectiveness of frat diagnostic therapy on these variables (except obsessive thoughts) was different in ERP patients (p <0.05) and transdiagnostic treatment in reducing and experiential avoidance and improvement in, cognitive emotion regulation, are more effective than ERP treatment.
Conclusion: The results of the present study were discussed with regard to the studies conducted in this field and the content of the transdiagnostic treatment protocol and ERP treatment
