Use of an Augmented Exposure and Response Prevention Procedure in the Treatment of Obsessive-Compulsive Disorder: A Case Report

This case report describes the assessment and treatment of a 21-year-old male with obsessive-compulsive disorder (OCD) using an intensive exposure and response prevention (ERP) treatment program. The patient and his father received daily 2-hour ERP sessions delivered across 10 consecutive weekdays, and monthly follow-up appointments. In addition to the condensed treatment schedule, ERP procedures were augmented to address ongoing family conflict and depressive symptoms. To the best of the our knowledge, this is the first study to include such treatment adaptations within the context of intensive ERP for an adult with OCD. Results indicated target behaviors decreased over the 2-week intensive treatment phase and were maintained during 4 months of follow-up. Ancillary outcomes reported by the patient and his father included more frequent engagement in activities of daily living and improved family communication. Outcomes of this study provide an important step toward establishing recommendations regarding ERP session frequency, especially among patients with comorbid disorders.
