Abstract

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