Obsessive-compulsive disorder (OCD), characterized by intrusive thoughts (obsessions) and related behavioral rituals (compulsions), is a common psychiatric illness that often emerges in childhood and causes life-long disability in over 50% of patients. Psychological theory suggests that OCD symptoms are driven by a person's difficulty disengaging their feelings from simple tasks (e.g. washing hands, locking a door) due to excessive anxiety about performance errors. Cognitive behavioral therapy (CBT), the gold standard treatment for OCD, repeatedly exposes patients to their OCD-stressor until this anxiety is reduced. While CBT is typically more effective in teenagers than adults, patients from both age groups are usually left with residual symptoms, highlighting the need for better treatments. In this study, CBT will be studied in both teen-aged and adult patients. Two groups, both with childhood onset OCD, will be randomized to either CBT for OCD or stress management training (SMT), an active therapy but with minimal effects on OCD symptoms. The investigators will also study age-matched, healthy controls as comparison subjects. Before and after 12 weeks of CBT, all subjects will undergo functional Magnetic Resonance Imaging (fMRI) scans to see what regions of the brain become active when a concentration task is performed and how that activation is changed after CBT. The purpose of this study is to demonstrate the brain changes associated with CBT treatment and how differences in these changes in teenage compared to adult patients may drive differences in CBT response.

Study summary:

While the study itself is of parallel design for its data-collection and measurement purpose, it is listed as a partial-crossover design in the IRB-approved protocol because subjects randomized to the SMT group are given the option of entering 12-weeks of CBT sessions after all of their SMT data collection. To understand brain changes that occur with CBT compared to SMT in both age groups, the investigators will collect fMRI data before and after therapy. Some limited data will be collected in patients who are initially randomized to SMT but then opt to crossover to CBT. fMRI data will also be collected in healthy teens and adults before and after 12 weeks (but without intervening therapy) to allow the investigators to control for the simple effects of time that may cause brain changes that are not related to therapy.
