Free Online OCD Test | Developed by Psychologists
The OCD test is an indicative screening tool developed by psychologists to help adults find out whether their repetitive rituals, intrusive thoughts or compulsive checking may indicate obsessive-compulsive disorder. The test is based on the internationally validated OCI-R and Y-BOCS instruments and the diagnostic criteria of DSM-5.
Do thoughts you do not want keep coming back, and do you struggle to push them away? Do you check the door, the gas or the hob even though you know you have already turned everything off? Do you need objects arranged in a precise way, and does any deviation from that arrangement make it impossible to concentrate? Do you spend an hour or more each day on mental rituals? This may be more than a cautious personality or everyday anxiety.
This OCD test will help you find out whether your difficulties may indicate obsessive-compulsive disorder. It is an indicative screening tool covering four clinically validated areas: contamination and washing rituals, checking and heightened responsibility, the need for symmetry and perfectionism, and intrusive thoughts alongside mental rituals.
The result is not a substitute for professional diagnosis, but it can be a useful first step to help you better understand what you are experiencing and decide whether it is worth discussing your situation with a psychologist.

What is OCD in adults?
OCD, or obsessive-compulsive disorder, is a chronic mental health condition characterised by two interrelated phenomena: obsessions and compulsions. Obsessions are recurrent, unwanted and difficult-to-dismiss thoughts, images or impulses that cause marked distress. Compulsions are repetitive, ritualised behaviours or mental acts carried out in response to an obsession, with the aim of reducing tension or preventing a feared event.
OCD is not simply being overly clean or a perfectionist. In more serious cases it can occupy an hour or more each day, significantly impair occupational performance, relationships and quality of life, and cause intense psychological suffering. According to estimates from the World Health Organization (WHO), OCD ranks among the ten most burdensome conditions in terms of its impact on daily functioning.
The lifetime prevalence of OCD is estimated at between 1.6 and 2.3 per cent of the population, with the disorder most commonly emerging in adolescence or early adulthood. In men, onset tends to be earlier (on average around the age of 20); in women, symptoms typically reach their full expression slightly later. A large proportion of people with OCD wait an average of eleven years before seeking professional help after the first appearance of symptoms, primarily because they feel ashamed of their obsessions or regard their compulsions as simply part of who they are.
The defining feature of OCD that distinguishes it from ordinary worry or perfectionism is the ego-dystonic nature of obsessions: the thoughts or impulses are in direct conflict with the values, beliefs and wishes of the person concerned. Someone with OCD does not want these thoughts and generally knows perfectly well that they are exaggerated or irrational. That is precisely one of the reasons why they feel so frightening, and why many people are so ashamed of them.
Can an adult have OCD that has never been identified?
Yes, and it is surprisingly common. OCD is consistently one of the most underdiagnosed mental health conditions. Many adults with OCD spend years believing they are simply anxious, excessively conscientious, or obsessed with tidiness, unaware that their difficulties have a clear clinical form and a highly effective treatment.
Three factors in particular contribute to late recognition. First, the manifestations of OCD are highly varied: from classic handwashing through repeated checking to so-called pure OCD, in which obsessions are predominantly mental with no visible rituals. Second, many people feel deeply ashamed of their obsessions and actively conceal them, especially when those obsessions involve intrusive sexual, religious or violent content. Third, OCD symptoms are easily confused with other conditions, including generalised anxiety disorder, depression, or obsessive-compulsive personality disorder (OCPD), which is clinically entirely distinct from OCD.
A late diagnosis of OCD is not a failure. For many adults, receiving a diagnosis is actually a relief, because it explains years of difficulty and opens the door to effective help.
How does OCD manifest in adults?
OCD differs from person to person, but research consistently identifies four main symptom domains, which also form the basis of this test. In each of these domains, OCD comprises two elements: an obsession (an intrusive thought or fear) and a compulsion (a ritual or behaviour aimed at neutralising the obsession or preventing the feared outcome).
| Domain | Clinical grounding and description |
|---|---|
| 1. Contamination and washing | The Washing subscale of the OCI-R (Foa et al., 2002). Measures distress related to contamination, washing and cleaning rituals, and avoidance behaviour typical of contamination OCD. Obsessions typically centre on bacteria, illness, poisons or the idea of negative properties being transferred through touch. |
| 2. Checking and responsibility | The Checking subscale of the OCI-R (Foa et al., 2002) and the responsibility dimension of the Y-BOCS (Goodman et al., 1989). Encompasses repeated checking, an inflated sense of responsibility, and harm OCD. The compulsion takes the form of repeated physical or mental checking of locks, switches or safety. |
| 3. Ordering, symmetry and perfectionism | The Ordering subscale of the OCI-R (Foa et al., 2002). Encompasses the not-just-right experience (NJRE), the need for symmetry and precision, and the repetition of actions until a sense of correctness is achieved. The compulsion may be physical (rearranging objects) or mental (repeating an action until it feels right). |
| 4. Intrusive thoughts and mental rituals | The Obsessing and Neutralising subscales of the OCI-R (Foa et al., 2002). Encompasses ego-dystonic obsessions, OCD with themes of harm, sexuality or religion, mental compulsions, and thought-action fusion (TAF). This type of OCD is often the hardest to identify because the rituals are not visible to others. |
Many people with OCD experience symptoms across more than one domain. The test will show you not only an overall score but also which domain your symptoms are strongest in.
Who is this OCD test for?
The test is intended for adults who have been noticing repetitive thoughts, rituals, compulsions or patterns of behaviour that cause them distress or interfere with their daily functioning.
The test may be particularly useful if:
- you are troubled by recurring intrusive thoughts or images you do not want and find difficult to dismiss
- you carry out rituals (washing, checking, ordering, counting) that you know are excessive but cannot bring yourself to skip
- you attach great moral significance to your thoughts, as though the mere fact of having them says something bad about you
- you need objects arranged in a precise way, and having them moved causes you marked distress
- you repeatedly check things (locks, appliances, messages) even though you know you have already done everything correctly
- rituals or obsessions take up an hour or more of your day, or are interfering with your work, relationships or leisure time
The test is also suitable for those who are unsure whether they are dealing with OCD or simply an anxious disposition. The result will help name the situation more clearly and indicate whether seeking professional support makes sense.
How does this OCD test work and what is it based on?
The test draws on three internationally recognised and scientifically validated instruments that underpin modern clinical diagnostics and screening for OCD.
Y-BOCS (Yale-Brown Obsessive Compulsive Scale) – Goodman et al. (1989). The gold standard for clinical assessment of OCD severity, on which treatment protocols worldwide are built. Evaluates time, distress, functional impairment, resistance and control over both obsessions and compulsions. Scale 0–40, categories: subclinical (0–7), mild (8–15), moderate (16–23), severe (24–31), extreme (32–40).
DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) – APA (2013). OCD criteria: A) presence of obsessions and/or compulsions; B) time-consuming (>1 hour per day) or clinically significant impairment of functioning; C) symptoms not attributable to a substance or another medical condition; D) not better explained by another mental disorder.
The test contains 20 questions distributed evenly across four domains (five per domain), corresponding to the subscales of the OCI-R. Each question is rated on a scale from 0 to 3 (never, rarely, fairly often, almost always). A total score of between 0 and 60 places you in one of four categories. You also receive a sub-score for each domain, so you can see exactly where your symptoms are strongest.
Completing the test typically takes between 8 and 12 minutes.
Is an online OCD test reliable?
This test serves as an indicative screening tool, not a clinical diagnosis. This means that it:
- can flag possible symptoms of obsessive-compulsive disorder
- helps you better name and organise what you have been repeatedly experiencing in your day-to-day life
- shows which of the four domains your symptoms are most pronounced in
- does not replace a professional psychological or psychiatric assessment
The OCI-R, on which the test is based, is one of the best-validated screening tools for OCD available in international psychological practice and research. Even so, an accurate diagnosis of obsessive-compulsive disorder can only be made by a psychologist or psychiatrist following a comprehensive clinical assessment.
If your result indicates a more pronounced level of symptoms, or you feel the difficulties described very closely match your own experience, we recommend following up with a psychologist specialising in OCD and anxiety disorders.
What should you do if the test shows more pronounced OCD symptoms?
A test result is not a diagnosis. It is a signal that it is worth taking the next step. The recommended course of action is to consult a psychologist experienced in working with OCD, who will carry out a more detailed assessment of your situation and suggest an appropriate way forward. If needed, your psychologist may recommend a psychiatric evaluation, where OCD can be formally diagnosed and a combination of therapy and medication considered.
The gold standard treatment for OCD is Exposure and Response Prevention (ERP) within cognitive behavioural therapy (CBT). Research consistently confirms that 60 to 80 per cent of clients who complete a course of ERP achieve significant relief from symptoms. The therapy involves deliberately confronting feared situations without performing a ritual, which gradually teaches the brain to stop evaluating the obsession as a genuine threat. In more severe cases, a psychiatrist may consider prescribing an SSRI, which is used in OCD at specifically higher doses than in the treatment of depression.
A diagnosis of OCD in adulthood is not an ending. For many people it is, in fact, a beginning. It makes it possible to stop explaining rituals and obsessions as personal weakness or moral failure, and to choose an approach that genuinely helps.
Why is it important to address suspected OCD early?
Untreated OCD tends to deepen over time. Rituals grow longer, areas of avoidance expand, and obsessions gradually encroach on more and more areas of life. Many adults with OCD describe years of shame, secrecy and exhaustion from hiding their rituals from those around them. The average delay between first symptoms and the start of treatment is over ten years worldwide.
Untreated OCD significantly increases the risk of depression and social isolation. It is estimated that co-occurring depression affects up to 67 per cent of people with OCD. Early and targeted care substantially reduces these risks, and quality of life can improve very quickly, sometimes after just the first few weeks of ERP therapy.
The goal of professional support is not only to reduce the number of rituals or the frequency of obsessions. It is also to reclaim the time, energy and freedom that OCD gradually takes away, and to learn to live a full life without unnecessary restriction.

Professional credentials
The OCD test is designed as a psychologically grounded screening tool for adults, based on clinically established and scientifically validated methods: OCI-R (Foa et al., 2002), Y-BOCS (Goodman et al., 1989) and the diagnostic criteria of DSM-5 (APA, 2013). It covers four clinically relevant dimensions of OCD: contamination and washing, checking and responsibility, ordering and symmetry, and intrusive thoughts and mental rituals. The test is not intended to establish a diagnosis; its purpose is to help identify possible OCD symptoms and provide an initial orientation towards what may be worth addressing with a professional. The test content is reviewed regularly in line with current developments in clinical psychology and psychiatry.
Frequently asked questions
Is the OCD test free and anonymous?
Yes, the test is completely free and anonymous. It does not require registration or the submission of any personal details. Your responses are not sent or stored anywhere, and all calculations take place directly in your browser.
How accurate is an online OCD test?
The test is based on the OCI-R, an instrument with a clinical cut-off of 21 points and a Cronbach's alpha of 0.81 to 0.93 in clinical samples, and on the Y-BOCS, the gold standard for OCD assessment. It is an indicative screening tool, not a diagnosis. An accurate diagnosis of obsessive-compulsive disorder can only be made by a psychologist or psychiatrist on the basis of a comprehensive clinical assessment.
How long does the OCD test take to complete?
Completing the test typically takes between 8 and 12 minutes. The test contains 20 questions. We recommend setting aside a quiet moment and answering honestly based on the past two weeks rather than just how you feel right now.
What is the difference between OCD and OCPD?
OCD (obsessive-compulsive disorder) and OCPD (obsessive-compulsive personality disorder) are two entirely distinct diagnoses, despite the similarity of their names. In OCD, obsessions and rituals are ego-dystonic: the person does not want them, experiences them as alien, and finds them distressing. In OCPD, perfectionism, rigidity and control are ego-syntonic: the individual perceives them as part of their personality and usually does not regard them as a problem. This test relates exclusively to OCD symptoms.
Does OCD present differently in women and men?
Yes. In men, OCD tends to emerge earlier (adolescence, early adulthood); in women, the disorder typically reaches its full expression somewhat later, and the content of obsessions may differ. Contamination OCD and postpartum OCD (with obsessions centring on the safety of a newborn) are more common in women, for example. Overall prevalence and response to treatment are, however, broadly similar across both sexes.
What happens after I complete the test?
Once you have answered all 20 questions, your result appears immediately. You will see your total score, placement in a category (minimal, mild, pronounced or severe OCD symptoms), a sub-score for each of the four domains, and specific recommendations for next steps. The result is not sent or stored anywhere. The test is fully anonymous.
What is the difference between OCD and an anxiety disorder?
OCD and anxiety disorders such as generalised anxiety disorder or panic disorder share a number of symptoms, particularly intense distress and avoidant behaviour. The key distinguishing feature is the presence of rituals: always present in OCD, absent in GAD or panic disorder. The second key difference lies in the content of the obsessions: OCD is characterised by specific, recurring thematic clusters (contamination, harm, symmetry, taboo thoughts), whereas concerns in GAD relate to realistic, everyday topics. Since 2013, DSM-5 has classified OCD in its own separate category, distinct from the anxiety disorders.
Is OCD treatable?
Yes. OCD is among the mental health conditions with the strongest scientific evidence base for treatment. Exposure and Response Prevention (ERP) within CBT brings significant relief to 60 to 80 per cent of clients. Therapy can be delivered in person or online, with research confirming comparable effectiveness across both formats. In more severe cases, a combination of ERP and SSRI medication is effective. If a suspicion of OCD is confirmed, professional help is available and the outcomes are highly encouraging.
