Cognitive-Behavioural Therapy (CBT) is a highly effective treatment for childhood obsessive-compulsive disorder. This treatment involves gradually exposing children to feared situations while they practise managing their distress. Despite strong research evidence that this treatment is effective, it is still not widely available. More practitioners therefore need to be trained and supported to offer CBT. For more information, see Vol. 1, No. 3 of the Children’s Mental Health Research Quarterly.
