Acta Psychiatr Scand 2004: 110: 4–13. © Blackwell Munksgaard 2004. To review the extant literature on the long-term outcome of child/adolescent-onset obsessive–compulsive disorder (OCD). Medline and Psychlit databases were systematically searched for articles regarding long-term outcomes of child/adolescent-onset OCD. Meta-analysis regression was applied to evaluate predictors and persistence of OCD. Sixteen study samples ( n = 6–132; total = 521 participants) in 22 studies had follow-up periods ranging between 1 and 15.6 years. Pooled mean persistence rates were 41% for full OCD and 60% for full or subthreshold OCD. Earlier age of OCD onset ( z = −3.26, P = 0.001), increased OCD duration ( z = 2.22, P = 0.027) and in-patient vs. out-patient status ( z = 2.94, P = 0.003) predicted greater persistence. Comorbid psychiatric illness and poor initial treatment response were poor prognostic factors. Although psychosocial function was frequently compromised, most studies lacked comprehensive outcome measures. Long-term persistence of pediatric OCD may be lower than believed. Future studies should include broader measures of outcome including symptomatic persistence and functional impairment in multiple domains. [ABSTRACT FROM AUTHOR]
