Objective: To examine whether obsessive-compulsive disorder (OCD) symptom subtypes are associated with response rates to cognitive-behavioural therapy (CBT) among pediatric patients. Method: Ninety-two children and adolescents with OCD (range = 7-19 years) received 14 sessions of weekly or intensive (daily psychotherapy sessions) family-based CBT. Assessments were conducted at baseline and post-treatment. Primary outcomes included scores on the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), remission status, and ratings on the Clinical Global Improvement (CGI) and Clinical Global Impression - Severity (CGI-Severity) scales. Results: Seventy-six per cent of study participants (n = 70) were classified as treatment responders. Patients with aggressive/checking symptoms at baseline showed a trend (P = 0.06) toward improved treatment response and exhibited greater pre/post-treatment CGI-Severity change than those who endorsed only non-aggressive/checking symptoms. Step-wise linear regression analysis indicated higher scores on the aggressive/checking dimension were predictive of treatment-related change in the CGI-Severity index. Regression analysis with CY-BOCS score as the dependent variable showed no difference between OCD subtypes. Conclusion: Response to CBT in pediatric OCD patients does not differ substantially across subtypes.
