Study hypothesis
To evaluate the efficacy of cognitive behavioural treatment for children and adolescents with obsessive compulsive disorder. OCD is a severely handicapping chronic relapsing psychological disorder with affects 0.5% to 2% of the population. 50% of adults with OCD develop the condition in adolescence, and 50% of the children with OCD continue to be disabled by it in adulthood. Although cognitive behavioural treatment (CBT) is the first choice treatment in childhood according to recent consensus guidelines, there has only been one RCT in adolescents and children. That study suffers from difficulties of interpretation and used a less powerful form of CBT than the best currently used with adults. RCTs in adulthood have found that 70& of patients with OCD benefit from CBT, and remain well following the end of treatment.
Research Objectives: To carry out a trial of a manulised cognitive behavioural treatment for obsessional compulsive disorder in children and adolescents, in order to ensure that it is effective in reducing the level of symptoms. To investigate the extent of the improvements in functioning resulting from the treatment method and compare them with the effects of time spent waiting for treatment.

Primary outcome measure
The clinical status of the children and adolescents will be the main focus of the trial. The following tools will be used:
1. KIDDIE-SADS or equivalent semi-structured interview used to assess Mental state of the children
2. YBOCS (child version) used to measure obsessional compulsive symptoms by interview
3. Obsessive compulsive Inventory (OCI) - self-report measure of OCD
4. Responsibility Interpretation Questionnaire (RIQ) - self-report to measure cognitions specific to the treatment methods
5. Children's Depression Inventory (CDI)
6. Multidimensional Anxiety Scale for children (MASC) - self report
7. National Institute of Mental Health (NIMH) global obsessive compulsive scale
Following the example of most other studies in this field the YBOCS total score is considered to be the main focus of analysis.
