OCI-R is a self-report OCD symptom scale assessing distress from checking, washing, ordering, obsessing, hoarding, and neutralizing behaviors over the recent period.
Formula: Approx OCI-R total = (sum of 6 domain average ratings) x 3, range 0-72.
The OCI-R was developed by Foa and colleagues as an 18-item, six-domain measure (checking, washing, ordering, obsessing, hoarding, neutralizing) with strong reliability/validity for OCD symptom severity monitoring. A score around 21 is often used as a screening threshold in adult samples, but this implementation uses domain averages multiplied by 3 to approximate the 18-item total and should not be treated as a full-form equivalent.
Higher OCI-R scores indicate greater obsessive-compulsive symptom burden and support specialized OCD-focused evaluation.
Use when OCD symptom domains are suspected and a structured symptom-burden screen is needed.
This version uses domain averages to estimate total burden and is not a substitute for full 18-item administration or diagnostic interview.
