The Spanish version of the Obsessive-Compulsive Inventory-Revised (OCI-R): Reliability, validity, diagnostic accuracy, and sensitivity to treatment effects in clinical samples
MetadataShow full item record
This study examines the psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R) in Spanish and Argentinean samples. 90 OCD patients, 31 with non-OCD anxiety disorders and 84 non-clinical individuals completed the Spanish version of the OCI-R along with other OCD, depression, anxiety, and OCD-related cognition measures. The OCI-R showed significant associations with both OCD severity and other OCD symptom measures, beyond the relationships with depression, anxiety, and worry. The questionnaire also differentiated OCD from other anxiety disorders, except on the ordering and hoarding subscales. The relationships between the OCI-R subscales and dysfunctional beliefs were consistent with predictions based on cognitive models of OCD, although the coefficient sizes were generally weak. Our findings also indicate that the OCI-R is useful as a screening instrument and diagnostic tool, and has been shown to be sensitive to treatment.
