Obsessive compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions, and affects approximately 1–2% of youth.[1; 2] Although OCD may develop in adulthood,[3] a majority of cases report symptom onset during childhood.[4] Youth with OCD frequently experience co-occurring psychiatric conditions including anxiety disorders, attention deficit hyperactivity disorders (ADHD), major depressive disorders (MDD), chronic tic disorders (CTDs) and oppositional defiant disorder (ODD).[5; 6] Youth with OCD experience functional impairment,[7] disrupted family functioning,[8] and a poor quality of life.[9] As OCD symptoms rarely remit without treatment,[10] effective and efficient treatments are essential.
