An Internet administered treatment program for obsessive-compulsive disorder: A feasibility study

The present study evaluates efficacy of a new Internet-administered cognitive behavioral therapy (CBT) protocol, The OCD Program, designed to treat obsessive-compulsive disorder (OCD) remotely. This protocol comprises 8 online lessons delivered over 8 weeks and incorporates cognitive and behavioral techniques. Twenty-two individuals with a principal diagnosis of OCD received CBT-based online lessons, homework assignments, twice weekly contact from a clinical psychologist, and automated emails. Eighty-one percent of participants completed the lessons within the 8-week program. Post-treatment and 3-month follow-up data were collected from 21/21 (100%) and 19/21 (91%) participants, respectively. Participants improved significantly on the primary outcome measures, the Yale-Brown Obsessive Compulsive Scale and Obsessive Compulsive Inventory-Revised, with within-groups effect sizes (Cohen's d) at follow-up of 1.28 and 0.60, respectively. Participants rated the procedure as highly acceptable despite receiving an average of only 86 min (SD = 54.4 min) telephone contact with the therapist over the 8 weeks. These results provide preliminary support for efficacy of Internet-administered treatment for obsessive-compulsive disorder.
