Obsessive-Compulsive Inventory-Revised

The Obsessive-Compulsive Inventory-Revised (OCI-R) is a self-report measure for assessing symptoms of obsessive-compulsive disorder (OCD). It consists of 18 items composing 6 subscales: washing, checking, ordering, obsessing, hoarding and neutralizing. It is a highly useful diagnostic screening instrument in research and clinical settings. The revised OCI (OCI-R) improves on the parent version in 3 ways: It eliminates the redundant frequency scale, simplifies the scoring of the subscales, and reduces overlap across subscales.
