Abstract
INTRODUCTION: The Obsessive-Compulsive Inventory-Revised (OCI-R) is a widely used self-report instrument developed to overcome the problems with the available instruments. The aim of this study was to assess the psychometric properties of the revised Obsessive Compulsive Inventory (OCI-R) in Turkish sample. METHODS: The psychometric properties of the Turkish version of the Obsessive-Compulsive Inventory-Revised (OCI-R) were assessed in clinical samples (n=44 for patients with obsessive-compulsive disorder (OCD), and n=44 for patients with major depression (MD) and a non-clinical student sample (n=287). RESULTS: The confirmatory factor analysis demonstrated that the original six-factor structure was valid in the Turkish sample. The overall and each of the subscales showed moderate to good internal consistency and convergent validity as well as test-retest reliability. However, the Cronbach's alpha was excessively low for the hoarding subscale in the OCD group. The total and subscale scores of the OCI-R satisfied at discriminating patients with OCD from both patients with MD and healthy controls, with an exception of the neutralizing subscale. CONCLUSION: The Turkish version of the OCI-R did not reveal sound psychometric properties. Findings are discussed in the light of current theoretical considerations.
