The efficacy of a protocol of accelerated resolution therapy (ART) on clinical symptoms of obsessive-compulsive disorder (OCD)

Background: Obsessive-compulsive disorder is one of the most common debilitating neuro-psychological disorders, which is characterized by features such as recurrent obsessions or compulsions or both, and disrupts the life of the affected person. Aims: This research aimed to design and validate the therapeutic protocol of accelerated resolution therapy (ART) and to evaluate its effectiveness on the clinical symptoms of obsessive-compulsive disorder (OCD). Methods: The research was carried out in two stages, which were designed and implemented for this specific purpose. In the first stage, the initial treatment protocol was developed based on a comprehensive review of previous studies, existing methods, and guidelines. After that, the validity of the protocol was evaluated by two qualitative and quantitative methods by calculating the content validity ratio.In stage two of the research, a new protocol was tested with a single-subject study and multiple baseline controls. A 6-week follow-up was conducted to measure the protocol's effectiveness. The statistical population for this research comprised all patients diagnosed with obsessive-compulsive disorder who were referred to counseling centers in Urmia City. Out of the total population, 4 patients were selected through a structured diagnostic and clinical interview, based on the criteria of DSM-5-TR, using the available sampling method. Patients participated in the research after meeting the entry criteria and not meeting the exit criteria. The effectiveness of the treatment protocol during 3 stages (baseline, treatment, and follow-up) was evaluated using the revised obsessive-compulsive questionnaire. Results: Based on the results of the CVR index, the developed protocol can be implemented to reduce the clinical symptoms of obsessive-compulsive disorder in patients. Conclusion: It appears that accelerated resolution therapy may alleviate the symptoms of obsessive-compulsive disorder and should be considered in macro health management programs.
