Under the proposed controlled trial, we plan to examine the efficacy of daily cognitive-behavioral psychotherapy to 50 consecutive children and adolescents who enroll in the UF OCD program. Children will be randomized to one of two treatment conditions: one consists of receiving cognitive-behavioral therapy every weekday for three-weeks; the other consists of receiving treatment as usual, which consists of once per week outpatient cognitive-behavioral therapy sessions . As compared to the once per week therapy condition, we predict decreases in OCD, general anxiety, and depressive symptomatology, and functional impairment at post-intervention for youth in the daily therapy condition.
