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.
