Obsessive-Compulsive Inventory-Revised (OCI-R)

What does the OCI-R measure?
Do you have thoughts you cannot shake, or urges to check, clean, or arrange things until they feel "right"? The OCI-R covers six types of OCD symptoms in 18 items — washing, checking, obsessing, mental neutralizing, ordering, and hoarding. About 5-8 minutes.
It started as a 42-item inventory. Foa and colleagues trimmed it to 18 in 2002 because the shorter version turned out to work just as well for screening and tracking treatment. It is one of the more common tools in the area, mostly because it is short enough to use repeatedly.
Domains
- Washing — excessive washing and cleaning
- Checking — repeated checking behaviors
- Obsessing — distressing intrusive thoughts
- Mental Neutralizing — mental rituals
- Ordering — arranging and symmetry needs
- Hoarding — difficulty discarding items
