The OCI-R is one of the most widely used self-report OCD measures. Eighteen items, six 3-item subscales each mapping to a distinct OCD symptom dimension. It's the natural choice when you suspect OCD or an OC-spectrum presentation and you want both a severity number and a profile of which symptom clusters are dominant. The dimension profile matters for treatment planning — washing-heavy presentations and checking-heavy presentations both score the same on a single-number measure but call for very different ERP (Exposure and Response Prevention) hierarchies. ## What it measures OCD symptoms across six 3-item subscales: | Subscale | Items | Cutoff | | ------------ | --------- | ------ | | Washing | 5, 11, 17 | ≥5 | | Checking | 2, 8, 14 | ≥6 | | Ordering | 3, 9, 15 | ≥6 | | Obsessing | 6, 12, 18 | ≥6 | | Hoarding | 1, 7, 13 | ≥6 | | Neutralizing | 4, 10, 16 | ≥4 | Subscale cutoffs from Abramowitz & Deacon (2006). Each item is rated 0–4 (Not at all / A little / Moderately / A lot / Extremely) over the past month. The total is the sum across all 18 items, range 0–72. ## When to send it * OCD differential screening — particularly when symptoms might be confused with GAD, social anxiety, or trauma-related avoidance * Pre/post for ERP protocols * Tracking which symptom dimensions respond to treatment (the dimension profile often changes faster than the total) * 4–6 week intervals during active OCD treatment The 18 items take about 5 minutes. Async administration works well; the 1-month time frame means you don't need it in the room. ## Scoring and severity cutoffs Sum of 18 items, range 0–72. The total cutoff for probable OCD is **≥21** (Foa 2002). The six subscale scores (each 0–12) and total surface in the live-scoring pill the moment your client submits, with the above-cutoff dimensions labeled. This is Rivet's first 6-subscale instrument — the pattern matches DASS-21 (3 subscales) and PCL-5 (4 clusters + total) but with more dimensions. ## OCI-R vs Y-BOCS The client fills in the OCI-R; you rate the [Y-BOCS](/clinical-templates/clinician-administered/y-bocs) in a structured interview. Beyond that, they answer different questions. The OCI-R tells you *which* symptoms are present, across six dimensions — washing, checking, ordering, obsessing, hoarding, neutralizing. That profile is what orients exposure and response prevention: it tells you what to build the hierarchy around. The Y-BOCS tells you *how bad* it is, by rating time spent, interference, distress, resistance and control for obsessions and compulsions separately. It is the severity measure the treatment literature uses, with response conventionally defined as a 35% drop. So: OCI-R at assessment to map the picture and as a self-report tracker between sessions, Y-BOCS when you need a defensible severity number or are measuring response to ERP or medication. ## Is it free to use? **Yes.** Free clinical use, per Foa and colleagues. ## Citation Foa, E.

Free clinical use; the verbatim canonical wording is preserved. ## When not to use it The OCI-R is a symptom-severity measure, not a diagnostic interview. A score above cutoff supports the OCD picture but doesn't replace the clinical interview, particularly when the differential includes trauma- related ritualistic behaviour, autism-spectrum restricted patterns, or psychotic-spectrum intrusive thoughts. For trauma-related symptoms in the differential, pair with the [PCL-5](/clinical-templates/screening/pcl-5). ## Related articles The 7-item generalized anxiety screen — often part of an OCD differential panel.
