The Obsessive Compulsive Inventory-Revised (OCI-R) (Foa et al., 2002) is an 18-item self-report questionnaire and measures OCD symptoms across 6 subscales including washing, checking, neutralising, obsessing, ordering and hoarding. The scale is suitable for use with adults and adolescents (16 years +; Piqueras et al., 2009).
