Summary

Obsessive-compulsive disorder affects approximately 2% of the population, frequently has its onset during childhood or adolescence and is potentially incapacitating. If not properly treated, this disorder tends to follow a chronic course. Pharmacotherapy with clomipramine and selective serotonin reuptake inhibitors (SSRIs), such as fluvoxamine, fluoxetine and sertraline, has been approved for pediatric OCD. However, up to 30% of patients may not benefit from these treatments, and the presence of residual symptoms is frequent among treatment responders. Cognitive-behavioral therapy (CBT) is also recognized as first line treatment for pediatric OCD, either administered in individual or group format. There is evidence suggesting equivalent efficacy for SSRIs and CBT in pediatric OCD, but there is no data on adaptive treatment strategies regarding such treatments on the long term outcome of OCD patients. The aim of this study is to verify, in a randomized design, if there is an optimal sequential treatment strategy for pediatric OCD, adopting the two most studied treatments for this disorder: an SSRI and group CBT (GCBT). The investigators hypotheses are: (1) both types of treatment will present similar efficacy in the short term (14 weeks); (2) for non-responders to the first type of treatment (fluoxetine up to 80mg/day or GCBT for 14 weeks), combined treatment (fluoxetine + GCBT for another 14 weeks) will be more effective than switching treatment modality (from fluoxetine to GCBT or from GCBT to fluoxetine for additional 14 weeks) after additional 14 weeks.
