The OCI-R (Obsessive-Compulsive Inventory — Revised) is an 18-item questionnaire about obsessive-compulsive experiences, grouped into six areas: washing, checking, ordering, obsessing (unwanted intrusive thoughts), hoarding, and mental neutralising. It is a well-validated, widely used OCD screening measure.
This is a self-check you can complete online in about four minutes. You get your score immediately, with a plain-language interpretation of what it may point to. It is a first orientation, not a diagnosis — a formal assessment of OCD is always made by a qualified professional.
Obsessive-compulsive experiences frequently co-occur with autism and ADHD, and intrusive thoughts or repetitive routines can mean different things in a neurodivergent life. The interpretation here is written to inform, not to alarm, and to help you decide whether talking it through with someone is a useful next step.

"What does this mean?" if a question is not clear, tap this under the question for a plain explanation.
"Not sure about my answer" if your answer is only an approximation, mark it. It does not change the score; it just shows where it may help to come back to it.
