Treating Obsessive-Compulsive Disorder in Intimate Relationships: A Pilot Study of Couple-Based Cognitive-Behavior Therapy

Although cognitive-behavioral therapy (CBT) involving exposure and response prevention (ERP) is an established treatment for obsessive-compulsive disorder (OCD), not all patients respond optimally, and some show relapse upon discontinuation. Research suggests that for OCD patients in close relationships, targeting relationship dynamics enhances the effects of CBT. In the present study, we developed and pilot tested a 16-session couple-based CBT program for patients with OCD and their romantic partners. This program included (a) partner-assisted ERP, (b) techniques targeting maladaptive relationship patterns focal to OCD (e.g., symptom accommodation), and (c) techniques targeting non OCD-related relationship stressors. OCD, related symptoms, and relationship functioning were assessed at baseline, immediately following treatment (posttest), and at 6- and 12-month follow-up. At posttest, substantial improvements in OCD symptoms, relationship functioning, and depression were observed. Improvements in OCD symptoms were maintained up to 1 year. Results are compared to findings from studies of individual CBT for OCD and discussed in terms of the importance of addressing interpersonal processes that maintain OCD symptoms.
