Children’s Yale-Brown Obessive Compulsive Scale (CY-BOCS)

The Children’s Yale-Brown Obsessive Compulsive Symptom Scale asks about symptoms of obsessive compulsive disorder in young people (4 to 18). It can be used as a clinician rated checklist or completed by the child/adolescent themselves, or with the help of their parent(s).

The CY-BOCS has good convergent validity with a measure of global psychological impairment, and reasonable divergent validity with measures of anxiety and depression. The CY-BOCS is a clinically useful tool for assessment of the degree of impairment and stress in child and adolescent patients diagnosed as suffering from Obsessive Compulsive Disorder.

A list of past and current symptoms are provided which are used to determine target obsessions and compulsions in treatment. A total score of between 0 and 118 is computed, however interpretation is best clinicans.
