Long-term course of pediatric obsessive-compulsive disorder: 3 years of prospective follow-up.

ABSTRACT

OBJECTIVE: This study assesses the long-term course of treatment-seeking youth with a primary diagnosis of DSM-IV OCD. METHOD: Sixty youth and their parents completed intake interviews and annual follow-up interviews for 3 years using the youth version of the Longitudinal Interval Follow-up Evaluation (Y-LIFE) and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Remission was defined as no longer meeting DSM-IV criteria for OCD for 8 weeks or more, and recurrence was defined as meeting full criteria for OCD for 4 consecutive weeks after having achieved symptom remission. Remission rates for youth were compared to rates of adults participating in the same study. RESULTS: The probability of achieving partial remission of OCD was 0.53 and the probability of achieving full remission was 0.27. Among the 24 youth participants who achieved remission, 79% stayed in remission throughout the study (mean of 88 weeks of follow-up) and 21% experienced a recurrence of symptoms. Better functioning at intake and a shorter latency to initial OCD treatment were associated with faster onset of remission (P<.001). CONCLUSIONS: Remission is more likely among youth versus adults with OCD. Treatment early in the course of illness and before substantial impact on functioning predicted a better course.
