Development and validation of a child version of the obsessive compulsive inventory.

Surprisingly, only 3 self-report measures that directly assess pediatric obsessive-compulsive disorder (OCD) have been developed. In addition, these scales have typically been developed in small samples and fail to provide a quick assessment of symptoms across multiple domains. Therefore, the current paper presents initial psychometric data for a quick assessment of pediatric OCD across multiple symptom domains, a child version of the Obsessive Compulsive Inventory (the OCI-CV). Data from a sample of over 100 youth ages 7 to 17 with a primary DSM-IV diagnosis of OCD support the use of the 21-item OCI-CV. Results support the use of the OCI-CV as a general index of OCD symptom severity and in 6 symptom domains parallel to those assessed by the revised adult version of the scale (OCI-R). The OCI-CV showed strong retest reliability after approximately 1.5 weeks in a subsample of 64 participants and was significantly correlated with clinician-rated OCD symptom severity and parent and child reports of dysfunction related to OCD. Significantly stronger correlations with self-reported anxiety than with depressive symptoms provide initial support for the divergent validity of the measure. Finally, preliminary data with 88 treatment completers suggest that the OCI-CV is sensitive to change.
