The psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R) subscales have not been validated in a clinical sample of individuals diagnosed with obsessive-compulsive disorder (OCD). Data were collected on 186 patients diagnosed with OCD and 17 patients diagnosed with generalized anxiety disorder (GAD) using the OCI-R and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Confirmatory factor analysis revealed an acceptable factor structure. Patients with a given primary symptom subtype were elevated on the corresponding subscale of the OCI-R compared to other OCD patients and patients with GAD. In addition, patients who acknowledged that symptom subtype as present but not primary on the Y-BOCS had elevated OCI-R scores on that scale compared to patients who did not endorse that symptom subtype and patients with GAD. Results indicate that the subscales of the OCI-R are valid measures of six symptom subtypes of OCD. The OCI-R is a psychometrically sound, brief instrument. The current data combined with previous efforts suggest that it is appropriate for clinical and non-clinical populations, and for clinical and research purposes. Further research should examine the sensitivity of the specific subscales to treatment effects, and the potential for adding more items to account for other symptom domains of OCD.
