Objective: The aim of this study was to evaluate the effectiveness of acceptance and commitment therapy (ACT) in treating obsessive compulsive disorder (OCD).
Method: In a single-subject experiment trial, the treatment process was carried out on a 39-year old male subject. The patient satisfied the DSM-IV-TR criteria for OCD and was assessed for pre-duration and post treatment. The scales used in this study included: The Yale-Brown Obsessive Compulsive Scale(Y-BOCS), Beck Depression Inventory-II-second edition (BDI-II), and Beck Anxiety Inventory (BAI). In addition, all scales were again completed by the subject at 1-month, 3-months, and 6-months follow-ups.
Results: The treatment led to reductions in symptoms of OCD, depression and anxiety. Gains were maintained at follow-ups.
Conclusion: The treatment approach appears to be effective in the treatment of OCD.
