Obsessive-compulsive disorder (OCD) can be successfully treated with cognitive behaviour therapy (CBT). However, as few patients have access to CBT, there is a strong push to develop and evaluate scalable and cost-effective internet-delivered interventions. BIP OCD is a therapist-guided online CBT intervention for pediatric OCD that has shown promise in trials conducted at a single site in Stockholm, Sweden. In this study, we evaluated if BIP OCD is an acceptable, feasible, and effective treatment in other countries and clinical contexts. Thirty-one patients were recruited at three different sites; a specialist OCD clinic in Gothenburg (Sweden), a specialist OCD clinic in London (United Kingdom), and a university-based clinic in Brisbane (Australia). Acceptability and feasibility measures included treatment adherence and feedback from therapists. Clinician assessments were conducted at baseline, post-treatment, and 3-month follow-up. The average module completion for the participants was 8.1/12 (SD = 3.2) and the majority of patients completed the BIP OCD treatment (100% in Gothenburg, and 55.6% in both London and Brisbane). Pooling data from the three sites, the within-group effect sizes from baseline to post-treatment on the Children’s Yale-Brown Obsessive-Compulsive Scale were in the expected range (bootstrapped Cohen’s d = 1.78; 95% CI 1.18-2.39), with an additional symptom reduction to the 3-month follow-up (bootstrapped Cohen’s d = 0.27; 95% CI 0.02-0.51). Participating therapists identified both advantages and difficulties supporting patients in this digital format. The results of this study suggest that the treatment effects obtained in the original BIP OCD trials can be generalized to other clinical contexts nationally and internationally. Lessons learned provide important information for successful implementation of BIP OCD in regular healthcare contexts.
