Psychometric properties of the OCI-R in a college sample.
Two studies examined the psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R; Psychol. Assessment 14 (2002) 485) in a nonclinical student sample. In Study 1, we investigated the factor structure and internal consistency of the OCI-R using a sample of 395 undergraduate students. At a second testing session 1 month later, 178 students completed the OCI-R. Test-retest reliability was examined using data from 94 students who completed the OCI-R in both sessions. Convergent validity was also assessed with the Maudsley Obsessive-Compulsive Inventory (MOCI). In Study 2, we further investigated the convergent and divergent validity of the OCI-R using a new sample of 221 students who completed a battery of measures of obsessive-compulsive symptoms, worry, and depression. There was a significant order effect for both the OCI-R and the MOCI: means of each measure were significantly lower when presented second. Despite the order effect, statistical analyses indicated that the OCI-R has adequate test-retest reliability for the full scale and subscale scores, solid factor structure, and high internal consistency. Convergent validity with other measures of obsessive-compulsive symptoms was moderate to excellent, and divergent validity was good. The results indicate that the OCI-R is a short, psychometrically sound self-report measure of obsessive-compulsive symptoms.
