The most important thing I’ve learned about OCD is that most people who have it don’t look like the stereotype. They’re not necessarily washing their hands obsessively or checking the stove repeatedly. If you’ve been Googling something like “OCD quiz” or “do I have OCD,” there’s a good chance you’re noticing something in yourself that doesn’t quite fit the picture you’ve always had in your head — and that’s exactly why I put this post together.

OCD very often looks like persistent, distressing intrusive thoughts — the kind you feel you shouldn’t be having — and the exhausting mental effort of trying to neutralise them. When I was going through my own difficult period with anxiety in my mid-twenties, I had no idea that the relentless mental loops I was caught in had a name, a framework, and — crucially — an effective treatment pathway. I spent two years thinking I was just an anxious, overthinking person. I wasn’t diagnosed with anything, but I understand now how easily OCD can be missed, misunderstood, or mistaken for “just anxiety.”
I want to be upfront: I’m not a therapist or clinician. I’m a mental health blogger with a BSc in Psychology, a postgrad certificate in Mental Health Communication, and a lot of lived experience. This screener is a reflection tool, not a diagnostic instrument. But sometimes having a structured set of questions in front of you is the thing that finally makes you go, “Oh. Maybe I should talk to someone about this.” If that’s what this does for you today, it’s done its job.
The OCD (Obsessive-Compulsive Disorder) Quiz: 10 Questions to Reflect On
Read through each question honestly and note how many you’d answer “Yes” to — even if it’s a reluctant or partial yes.
- Do you experience recurrent, unwanted thoughts, images, or urges that feel intrusive and difficult to control?
- Do these thoughts cause you significant distress or anxiety?
- Do you feel a strong need to perform certain actions, rituals, or mental behaviours to reduce the anxiety caused by these thoughts?
- Do you engage in repetitive checking behaviours (checking the door, the stove, messages sent, etc.)?
- Do you seek reassurance from others repeatedly about the same concerns, even when you’ve already been reassured?
- Do you avoid certain situations, objects, or places because they trigger your intrusive thoughts?
- Do you experience mental rituals — like counting, praying, repeating phrases, or mentally reviewing events — to “neutralise” an intrusive thought?
- Do these thoughts and any related behaviours take up more than an hour of your day, or significantly interfere with your life?
- Do you know logically that the thoughts are probably unfounded, yet still feel compelled to respond to them?
- Do you feel significantly ashamed or frightened by the content of the intrusive thoughts?
Give yourself 1 point for every “Yes.” Check what your score might mean below — but remember, this is a reflection tool, not a diagnosis.
What Your Score Might Mean
0–3: Significant OCD is less likely, though intrusive thoughts are near-universal — virtually everyone has odd, unwanted thoughts from time to time. If you scored in this range but still feel like something is off, distress around thoughts is always worth exploring with a professional if it is affecting your daily life. Low scores don’t invalidate your experience.
4–6: This suggests a moderate cluster of symptoms that may resonate with OCD, particularly if the thoughts and responses take up significant time or cause real distress. This range is worth taking seriously. Speaking to a GP or a therapist with OCD experience is a genuinely good next step — not because something is definitely wrong, but because you deserve clarity and support.
7–10: A strong pattern consistent with OCD. Please do take the IOCDF screener linked below and consider bringing the results to your GP or a mental health professional. I want to be clear here: OCD is highly treatable. ERP (Exposure and Response Prevention) therapy has a very strong evidence base and helps a great many people reclaim their lives. But the right kind of support matters enormously — not every therapist is trained in OCD-specific approaches, so it’s worth seeking someone who is.
What’s Really Going On Here?
OCD is fundamentally a cycle. An intrusive thought arrives — and intrusive thoughts, it’s worth knowing, are extremely common across the general population. Research by psychologists like Stanley Rachman and Adam Radomsky has shown that the vast majority of people experience unwanted, odd, or disturbing thoughts at some point. What makes OCD different isn’t the presence of intrusive thoughts but the meaning a person attaches to them, and the compulsive response that follows. If you believe the thought means something terrible about you — or that you must act to prevent a feared outcome — the anxiety escalates, and the compulsion provides temporary relief. That relief is the trap, because it teaches the brain that the compulsion was necessary.
Something I’ve noticed — both in my own experience with anxiety and in the enormous amount of reading I’ve done since — is how much shame wraps itself around OCD. Particularly with what’s sometimes called “Pure O” (primarily obsessional OCD), where the compulsions are largely mental rather than visible, people often suffer in complete silence for years. The thoughts can be deeply disturbing in content — about harm, religion, sexuality, relationships — and the person experiencing them is often the last person who would ever act on them. The horror they feel about the thought is, in many ways, evidence of how out of character it is for them.
From my own experience of being in an anxious loop for two years without understanding what was driving it, I know how isolating it feels to think your brain is just broken. It isn’t. There’s a well-understood mechanism at work, and there are evidence-based tools that genuinely help. Understanding the cycle — obsession, anxiety, compulsion, short-term relief, reinforcement — is often the first step toward breaking it.
Take a More Formal OCD (Obsessive-Compulsive Disorder) Assessment
If this quiz has resonated with you, I’d encourage you to work through one of these more clinically developed screening tools before speaking to your GP or a therapist. They’re free, brief, and designed to give you more structured information to bring to a professional conversation.
- International OCD Foundation Official Screener — The IOCDF is the definitive authority on OCD research and treatment. Their screener is a 4-question tool based on the OCI-4, which is psychometrically validated and widely respected. I’d consider this the most important one to complete. Take the IOCDF OCD Screener here.
- Mental Health America OCD Screening Tool — MHA is a major mental health organisation in the United States, and their OCD screening tool is clinically vetted and straightforward to complete. A useful second perspective. Take the MHA OCD Screening Tool here.
Please don’t use these tools as a substitute for professional support. If your results suggest significant OCD symptoms, bringing them to your GP, a psychiatrist, or a therapist trained in OCD (specifically ERP or I-CBT approaches) is the right next move. You deserve a proper assessment from someone qualified to provide one.
What I’d Suggest If This Resonates
First: please do speak to a professional. Everything I’m about to suggest is meant to complement that, not replace it. That said, I know from personal experience that the waiting lists can be long, the appointments can feel brief, and sometimes having something concrete to work through in the meantime genuinely helps.
If you’re at the beginning of understanding your symptoms and want a solid, evidence-based starting point, I’d recommend The Mindfulness Workbook for OCD: A Guide to Overcoming Obsessions and Compulsions Using Mindfulness and Cognitive Behavioral Therapy from New Harbinger. It’s grounded in CBT, written accessibly, and really helpful for building awareness of the obsession-compulsion cycle before you’re working with a therapist — or while you are.
If ERP (Exposure and Response Prevention) is something you’ve already heard about and you want a structured, practical guide to the gold-standard treatment approach, The ERP Workbook for OCD: A Practical Step-by-Step Guide to Break Free From Obsessive-Compulsive Disorder is a clear, approachable workbook that walks you through the process step by step. It’s not a replacement for a trained ERP therapist — but it can help you understand what the therapy involves and start building some of those skills.
If your intrusive thoughts are specifically centred around your relationships — persistent doubt about your partner, your feelings, or whether you’re in the “right” relationship — it may be worth looking into Relationship OCD (ROCD) specifically. ERP Therapy for Relationship OCD (ROCD): The Complete Guide to Breaking Free from Relationship Doubt addresses this subtype directly and is a valuable resource if that description resonates with you.
If you’ve got this far — whether your score was high or low — I hope something here has been useful. I know what it’s like to spend months quietly wondering whether the way your brain works is something you just have to live with. For most people with OCD, the answer is genuinely no — not because they can make the thoughts disappear entirely, but because it is absolutely possible to change your relationship with them, reduce their power, and get back to living your life. You’re not broken, you’re not dangerous, and you’re not alone in this. If today is the day you decide to look into it properly, I’m really glad this post was here for you. Take care of yourself — and please do reach out to a professional when you’re ready. — Lucy x
