What is an OCD test?
An OCD test online is a self-screening questionnaire that measures how often you experience obsessive-compulsive symptoms—unwanted thoughts (obsessions) and repetitive behaviors or mental rituals (compulsions). Tests Pro uses 12 items inspired by the Obsessive-Compulsive Inventory–Revised (OCI-R), a widely cited research measure.
You rate each item from “Not at all” to “Extremely” over the past month. The total runs from 0 to 48 on 12 items written in an OCI-R–style frequency format. Researchers often discuss 21 as a screen on the full 18-item OCI-R (Foa et al., 2002). Tests Pro uses 21 as an educational flag on this shorter quiz—not a validated cutoff for this form, and not a diagnosis.
People often search for an OCD test when intrusive thoughts feel sticky, when rituals take more time than they used to, or when a friend or clinician suggested a brief screening. A higher score is a reason to consider professional follow-up—not proof that you have OCD.
This free OCD test is for education and self-reflection only. Only a licensed mental health professional can diagnose obsessive-compulsive disorder after a full clinical assessment. Evidence-based treatments such as ERP and CBT help many people reduce symptom severity.

Important
Screening only — not a diagnosis
This OCD test is a self-screening tool for informational purposes. It cannot diagnose obsessive-compulsive disorder or any other condition.
Not a diagnosis
Only a licensed mental health professional can diagnose OCD using clinical interviews and established criteria.
Screening only
A score of 21 or higher is an educational flag on this 12-item quiz. The published OCI-R is an 18-item scale, and its research screen does not automatically transfer to this shorter form. Distress that interferes with daily life is a reason to seek care either way.
Seek professional help
If symptoms interfere with daily life, ERP-based therapy and other treatments can significantly reduce OCD severity.
Tests Pro does not provide medical advice, diagnosis, or treatment. Use this tool as a starting point for conversation with a qualified provider. Educational content last reviewed September 2026 (OCI-R–inspired format; not the official instrument).

How to interpret your OCD test score
Total scores range from 0–48 on this 12-item adaptation. A score of 21+ is an educational flag borrowed from research on the full 18-item OCI-R—not a validated cutoff for this shorter quiz, and not a label.
Minimal range
0–10 points
Few obsessive-compulsive symptoms endorsed at moderate or higher frequency on this screening.
Next step: If specific rituals or thoughts still cause distress, mention them to a doctor or therapist—they may not show up on a brief screen.
Mild to moderate range
11–20 points
Some OCD-related patterns may be present, but the total is below the educational flag of 21. Symptoms may still be situational or mild.
Next step: Track whether checking, washing, ordering, or intrusive thoughts are growing. Early CBT or ERP can prevent symptoms from worsening.
Elevated screening range
21+ points
The total is at or above 21 on this shorter quiz. That is an educational flag, not the validated OCI-R cutoff and not proof of OCD. Professional follow-up is worth considering if symptoms cause distress.
Next step: Schedule an evaluation with a psychologist or psychiatrist experienced in OCD. ERP and medication are effective for many people.
Common OCD symptom areas
The OCI-R covers these obsessive-compulsive domains:
- Washing: Excessive cleaning or fear of contamination.
- Checking: Repeatedly verifying locks, appliances, or work.
- Obsessing: Persistent unwanted thoughts that are hard to dismiss.
- Ordering: Need for symmetry, exactness, or things to feel "just right."
- Neutralizing: Counting, repeating, or mental rituals to undo thoughts.
- Hoarding: Difficulty discarding items due to fear of needing them later.
- Doubting: Uncertainty about whether an action was completed correctly.

FAQ
OCD test: questions answered
Everything you need to know before you take the free OCD test on Tests Pro.
Is this OCD test free?
Yes. The full screening and instant results are free. No account or payment is required.
What score indicates possible OCD on this test?
A total of 21 or higher is an educational flag on this 12-item screen. The full OCI-R (Foa et al., 2002) is 18 items, and a similar number is often cited there as a research screen. Crossing 21 here is not a diagnosis and is not a validated cutoff for this shorter quiz.
How accurate is this OCD screening?
The OCI-R is a validated research instrument, but any online self-report depends on honest answers and cannot replace a clinical interview. Use results to guide follow-up with a professional.
Can I retake the OCD test?
Yes. Retake after treatment or when symptoms change to track progress over time.
Is this OCD test a diagnosis?
No. Only a qualified mental health professional can diagnose OCD after a comprehensive assessment.
Where can I read more about scoring and next steps?
Tests Pro publishes guides on what an OCD test is, how OCI-R–style scoring works, and what to do after your results. Use them alongside—not instead of—professional care.
What is the difference between obsessions and compulsions?
Obsessions are unwanted, recurring thoughts or images. Compulsions are behaviors or mental acts performed to reduce anxiety from obsessions—such as checking, washing, counting, or seeking reassurance.
