Internet-Delivered Cognitive Behavior Therapy for Adolescents with Obsessive-Compulsive Disorder: An Open Trial

Background: International guidelines recommend Cognitive Behavior Therapy (CBT) as the first line treatment for pediatric obsessive-compulsive disorder (OCD). However, a substantial proportion of patients do not have access to such treatment. We developed and tested the feasibility, efficacy and acceptability of a novel therapist-guided, Internet-delivered CBT (ICBT) platform for adolescents with OCD. Methods: An interactive, age-appropriate ICBT platform (BiP OCD) was developed. Twenty-one adolescents (12-17 years) with a DSM-IV diagnosis of OCD and their parents were enrolled in the study. All participants received 12 weeks of ICBT with therapist support. The primary outcome measure was the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). Acceptability was assessed at post-treatment. Results: Participants completed on average 8.29 (SD = 3.0) of the 12 treatment chapters. Treatment yielded significant improvements on all clinician-, parent-and most self-administered outcome measures, with a large effect size of d = 2.29 (95% CI 1.5-3.07) on the CY-BOCS. Patients continued to improve at follow-up. At 6-month follow-up, 71% were classified as responders (>= 35% decrease on the CY-BOCS) and 76% as being in remission (CY-BOCS score <= 12). Average clinician support time was less than 20 minutes per patient per week. The majority of participants felt that BiP OCD was age-appropriate and rated the treatment as good or very good. Conclusions: ICBT could be efficacious, acceptable, and cost-effective for adolescents with OCD. More rigorously controlled studies are needed to further evaluate the treatment.
