Objective: To describe the characteristics of a series of children and
adolescents with obsessive-compulsive disorder (OCD) and evaluate the
outcome of treatment. Method: Type of symptoms, severity before and a
fter treatment and factors associated with outcome were examined in a
large group (n=82) of consecutive OCD cases referred for treatment. Re
sults: Most children (95%) had both obsessions and compulsions. Sympto
ms had been present for 2 years on average. Seventy-one per cent (n=57
) of all eligible patients completed a combined behavioural and pharma
cological protocol. Among these, there was a 68% remission rate and a
60% decrease of symptoms at 4 weeks. Comorbidity with oppositional def
iant disorder and high aggression scores were associated with poor out
come. Conclusions: Juvenile OCD can be treated effectively in a standa
rd clinical setting. Treatment programs of the kind described are acce
pted by young people. It remains to be seen whether in this age group
a combined treatment produces better results than medication alone or
cognitive-behaviour therapy alone.
