Abstract

The psychometric properties of a new scale, the Obsessive Compulsive Inventory (OCI; Foa, Kozak, Salkovskis, Coles, & Amir, 1998), were examined in a nonclinical student sample. The study was a partial replication of the original validation study by Foa et al. Test-retest reliability, internal consistency, and convergent validity were examined using a sample of 126 undergraduate psychology students. Statistical analyses (Pearson's r and Cronbach's alpha) indicated adequate test-retest reliability for the full scales and subscales (coefficients ranging from 0.69 to 0.88) and high internal consistency (all coefficients exceeding 0.7). Convergent validity with the Maudsley Obsessional Compulsive Inventory (MOCI; Hodgson & Rachman, 1977) was adequate for the full scales and for the Washing and Checking subscales (coefficients ranging from 0.61 to 0.75). The OCI is a useful supplement to existing self-report measures of obsessive-compulsive symptomatology.
