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. Your total score is compared to a validated cutoff (21+) used in OCI-R research to flag when formal evaluation may be helpful. Domain highlights can also show which symptom areas scored higher, such as checking, washing, ordering, or unwanted thoughts.
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 at or above the OCI-R cutoff suggests follow-up is worth considering—it does not mean you have OCD.
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.

How to interpret your OCD test score
Total scores range from 0–48. The OCI-R clinical cutoff is 21—use your result as a screening signal, 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 present but below the common OCI-R cutoff. Symptoms may 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
Score meets the OCI-R cutoff suggesting clinically significant obsessive-compulsive symptoms warranting professional follow-up.
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 score of 21 or higher matches the widely used OCI-R clinical cutoff. It suggests obsessive-compulsive symptoms strong enough to warrant professional evaluation—not a confirmed diagnosis.
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.
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.
