The Obsessive-Compulsive Inventory-Revised (OCI-R): psychometric properties of the Korean version and the order, gender, and cultural effects.
In this study, the psychometric properties of the Korean version of the OCI-R and the effects of order, gender, and culture on the inventory were examined in a nonclinical and in a clinical sample comprised of 702 college students and 91 patients with OCD. As a result, the original six-factor model is supported by the confirmatory factor analysis. The internal consistency, test-retest reliability, and the convergent and divergent validity of the OCI-R total and its subscales were good. Additionally, the receiver operating characteristic analyses showed that the OCI-R is an effective screening tool for OCD. For the negative results, the internal consistency of the neutralizing subscale was poor, and the hoarding and ordering subscale failed to distinguish patients with OCD from college students. Further, the divergent validity of the obsessing subscale appeared to be poor. A minor order effect on the OCI-R total score was observed-the decrease of the score when administered after another OCD symptom measure. No gender effects were found, whereas the cultural differences were found in some of the subscales.
