title: Psychometric properties of the Obsessive Compulsive Inventory-Revised among Icelandic college students.
abstract: In the present study, the psychometric properties of the Obsessive Compulsive Inventory-Revised (OCI-R) (Foa, et al., 2002) were investigated. The OCI-R was administered to a total of 816 Icelandic college students. The Maudsley Obsessive Compulsive Inventory (MOCI) and the Penn State Worry Questionnaire (PSWQ) were administered to a subsample of 304 students, and the PI-WSUR (Padua Inventory Washington State University Revision), the PSWQ and the Multidimensional Perfectionism Scale (MPS) to another subsample of 212 students. Also, 89 students filled in the OCI-R twice with two weeks in between. The factor structure of the instrument was replicated in a confirmatory factor analysis. Cronbach's alpha and test-retest reliabilities of the OCI-R total scale and all subscales were satisfactory. Further, the OCI-R total score showed a significantly higher correlation with the PI-WSUR and the MOCI than with the PSWQ or the MPS. Finally, conceptually similar scales of the OCI-R and the MOCI as well as the PI-WSUR showed higher inter-correlations than the correlations that were observed between conceptually more distinct scales. It is concluded that the Icelandic version of the OCI-R has strong psychometric properties in a student population.
