title: Psychometric properties and construct validity of the Obsessive-Compulsive Inventory--Revised: Replication and extension with a clinical sample.
abstract: The present study examined the psychometric properties and construct validity of the Obsessive-Compulsive Inventory--Revised (OCI-R) with the aim of replicating and extending previous findings, and addressing limitations of previous investigations. Individuals with OCD (n = 167) and other anxiety disorders (n = 155) completed the OCI-R, measures of OCD and related symptom severity, and measures of cognitive variables associated with OCD symptoms. Results indicate that the OCI-R is a psychometrically sound and valid measure of OCD and its various symptom presentations. Confirmatory factor analysis confirmed a six-factor solution. The instrument also evidenced good convergent validity, and performed well in discriminating OCD from other anxiety disorders. Theoretically consistent patterns of associations between OCI-R symptom-based subscales and OCD-related cognitive variables were found, and five of the six OCI-R subscales corresponded closely to identified OCD symptom dimensions. The OCI-R is recommended as an empirically validated instrument that can be used in a range of clinical and research settings for research on OCD.
