If you searched for an OCD test, you may be trying to work out whether repeated checking, intrusive thoughts, washing, ordering, or mental rituals have started to take too much space in your life. That question deserves a better answer than a made-up quiz score.
This page explains how to use the Obsessive-Compulsive Inventory-Revised, usually called the OCI-R, as a safer reference point than a made-up online quiz. The OCI-R is an 18-item self-report measure developed and validated by Foa and colleagues in 2002 to measure distress linked to obsessive-compulsive symptoms. Because its republication rights are not as clear as the PHQ-9 or GAD-7, this page does not reproduce all 18 items. It shows what the instrument covers, how the scoring works, and what a result can and cannot mean.
Key takeaways
- An OCD test can help estimate symptom load, but it cannot diagnose OCD.
- The OCI-R looks across six domains: washing, checking, ordering, obsessing, hoarding, and neutralising.
- The original validation work compared people with OCD, people with other anxiety disorders, and non-anxious controls; later work proposed practical severity bands.
- A high score is a reason to seek assessment, not proof that you have OCD.
- In England, OCD support usually starts with a GP or NHS Talking Therapies; Jersey has its own services and is not part of the NHS.

Before you start
An online OCD test cannot tell you whether you “are OCD”, whether a thought means something about your character, or whether a habit is serious enough to “count”. Diagnosis depends on a clinical assessment: the pattern of obsessions and compulsions, how much time they take, how much distress they cause, what you avoid, and whether another explanation fits better.
The useful question for a self-check is narrower: how much distress or interference do these symptoms seem to be causing right now? That is what the OCI-R was built to estimate.
Before using any score, keep three limits in mind.
First, OCD is not the same as being tidy. Someone can like order, dislike mess, or prefer routines without having OCD. OCD becomes more likely when thoughts, urges, images, or doubts feel intrusive and when rituals or avoidance start to run the day.
Second, intrusive thoughts are not confessions. Many people with OCD are frightened by thoughts that clash with their values. The presence of a thought is not evidence that you want it, endorse it, or will act on it.
Third, this page does not include depression or general-anxiety scoring. If a page mixes PHQ-9, GAD-7, and OCD scoring into one result, it may be useful for broad screening, but it is no longer an OCD-specific self-check.
OCD self-check questions
The OCI-R asks how much distress or discomfort you have felt over the past month across obsessive-compulsive symptom areas. It uses 18 items, scored from 0 to 4, where higher numbers mean greater distress. Because the instrument’s permission status for republication is not as clearly open as tools such as the PHQ-9 and GAD-7, this page does not reproduce all 18 item wordings.
You can still use the structure safely. Notice whether the past month has included distress in any of these six areas:
| Domain | What it asks you to notice |
|---|---|
| Washing | Fear of contamination, repeated cleaning, or feeling unable to stop washing or checking cleanliness. |
| Checking | Repeatedly checking locks, appliances, mistakes, harm, reassurance, or whether something bad might happen. |
| Ordering | Distress when things are not arranged, symmetrical, exact, or done in a particular order. |
| Obsessing | Unwanted thoughts, images, doubts, or urges that feel intrusive and hard to disengage from. |
| Hoarding | Difficulty discarding things because it feels unsafe, wrong, or intolerably distressing. |
| Neutralising | Mental rituals, counting, praying, repeating phrases, or doing something internally to make a thought feel less dangerous. |
For a true OCI-R score, use the original item set from a clinical source or rights-managed instrument listing that has the right to host it, such as the OCI-R listing on ePROVIDE or a licensed clinical assessment platform. Keep the wording unchanged and score each item from 0 to 4. The total possible range is 0 to 72.
As you answer, try not to argue with each item. The point is not whether the fear is rational. The point is whether the thought or behaviour has been distressing, repetitive, sticky, or hard to resist.
What your score may mean
The original OCI-R validation paper, published in Psychological Assessment, reported on samples including 215 people with OCD, 243 people with other anxiety disorders, and 677 non-anxious individuals. In that study, a total score around 21 helped distinguish people with OCD from people without a psychiatric diagnosis, while a lower cutoff around 18 helped distinguish OCD from other anxiety disorders.
Those cutoffs are not a diagnosis. They came from research samples, not from you, and not from a UK or Jersey population specifically. They are best read as signals about whether further assessment is worth considering.

Later benchmarking work proposed practical severity bands for OCI-R total scores:
| OCI-R total | How to read it |
|---|---|
| 0-15 | Lower symptom load. If distress is still meaningful, the low score does not make it unimportant. |
| 16-27 | Moderate symptom load. This is a sensible point to consider professional advice, especially if symptoms affect work, study, sleep, relationships, or avoidance. |
| 28+ | Higher symptom load. This is a stronger signal to seek assessment and support. |
Do not use one number to decide whether your experience matters. A low total can still hide one area that is causing real disruption. A high total can also be influenced by stress, grief, trauma, autism, tic disorders, depression, body dysmorphic disorder, or other conditions that need a more careful look.
If the thing you are checking is not OCD-specific, use the right tool for the right question. For example, a trauma self-check asks a different set of questions and should not be folded into an OCD score.
When to seek professional help
Consider speaking with a professional if obsessive thoughts, compulsions, or avoidance are taking more time than you want, making you late, affecting relationships, interfering with sleep, work, study, parenting, or faith practice, or making ordinary choices feel unsafe.
In England, you can usually start with a GP or refer yourself to NHS Talking Therapies if you are registered with a GP and meet the local eligibility rules. The NHS describes OCD treatment as usually involving cognitive behavioural therapy with exposure and response prevention, sometimes medication such as an SSRI, or a combination depending on severity. NICE guidance similarly places CBT with exposure and response prevention and SSRIs at the centre of care.
In Jersey, do not assume the NHS route applies. Jersey Talking Therapies is a Government of Jersey Health and Community Services service for adults living in Jersey, and Jersey Adult Mental Health Services says most people are referred by a GP or another professional. If you need urgent mental health help in Jersey, the crisis line is +44 (0)1534 445290.
If you feel at immediate risk of harming yourself or someone else, call 999 or go to the nearest emergency department. If you need to talk urgently, Samaritans are available on 116 123. In the UK, Shout offers free 24/7 text support by texting SHOUT to 85258.
Frequently asked questions
Can an online test diagnose OCD?
No. An online OCD test can show whether your answers resemble a pattern that is worth assessing. It cannot rule OCD in or out, and it cannot tell the difference between OCD and every other condition that can involve repetition, fear, doubt, avoidance, or intrusive thoughts.
What is the difference between being tidy and having OCD?
Being tidy is usually a preference. OCD is more likely when a thought, doubt, or feeling of incompleteness becomes distressing and when you feel driven to do something to reduce that distress, even when the action no longer feels useful or proportionate.
What happens if I score high?
A high score means it is worth speaking to someone qualified. It does not mean you have failed, that you are dangerous, or that OCD is certain. A GP, psychological therapist, or mental health professional can look at the full picture and discuss treatment options.
Are intrusive thoughts a sign of OCD?
They can be, but not always. Almost everyone has odd, unwanted, or upsetting thoughts sometimes. OCD is more likely when the thought becomes sticky, feels threatening because it happened, and leads to checking, reassurance-seeking, avoidance, mental review, or rituals.
