Checking OCD: The Fear of Making Mistakes
You check the front door three times before you can leave for work. You re-read an email four times before sending it, and even then you worry you missed a mistake. The fear that you have done something wrong, or will do something wrong, can feel endless.

What is checking OCD?
Checking OCD is a common pattern where the main compulsion is to check something over and over. The fear underneath is usually about making a mistake that could harm someone, or that could have serious consequences you cannot undo. You might check locks, appliances, paperwork, your own body, or even your memory of an event.
The checking feels necessary because the doubt is so loud. But the checking itself feeds the doubt. The more you check, the more your brain learns that checking is what keeps you safe. It never learns that you are safe without the check.
This is the same cycle that drives all OCD: an obsessive thought or fear leads to a compulsion to do something, which gives temporary relief, but the relief wears off and the fear comes back stronger. For a fuller explanation of this cycle, you can read more in What is OCD? Obsessions, compulsions and the cycle.
The doubt that never settles
The core of checking OCD is a specific kind of doubt. It is not the ordinary doubt everyone feels. It is a doubt that does not respond to evidence. You can check the door is locked, see it is locked, feel the bolt slide home, and still wonder if it is really locked. You can read your email three times, see no errors, and still worry you missed one.
This doubt is not a sign that you are careless or stupid. It is a symptom. The OCD brain has a fault in its error-detection system. It keeps sending a "something is wrong" signal even when nothing is wrong. The checking is your attempt to turn that signal off, but the signal does not turn off because the brain is not listening to the evidence.
Reassurance-seeking: the hidden compulsion
Not all checking is physical. You might ask someone else to check for you. "Can you just read this and see if it makes sense?" "Did I lock the back door?" "Do you think I hurt that person's feelings?" This is called reassurance-seeking, and it works exactly the same way as checking the door yourself. You get a moment of relief, and then the doubt comes back.
Reassurance-seeking can be harder to spot because it feels like you are being sensible. You are asking for help. But if you find yourself asking the same question over and over, or needing a specific person to reassure you before you can settle, it is likely a compulsion.
Family members and friends often get pulled into this. They want to help, so they answer the question. But each time they answer, they make the OCD stronger. If you are supporting someone with this, you can find practical advice in How to Support Someone With OCD.
How it can look in daily life
Checking OCD can attach to almost anything. Here are some common examples:
- Checking that the iron is unplugged, the stove is off, or the tap is closed, sometimes multiple times before leaving the house.
- Re-reading letters, emails, or text messages many times before sending, and sometimes after sending too.
- Checking your body for signs of illness, injury, or changes, and then checking again later.
- Going over your memory of a conversation to make sure you did not say something wrong or offensive.
- Checking that you have not hit someone with your car, sometimes circling the block to look again.
For a grandmother raising grandchildren in Kingston, this might look like checking the children's homework over and over, or checking the windows and doors every night long after the children are asleep. She knows logically the house is safe, but the worry does not stop.
A security guard in Sharjah might find himself checking the same CCTV feed several times during his shift, even though he knows he watched it a minute ago. He worries he missed something important, and the worry costs him his concentration for the rest of his shift.
What is ERP and how does it help?
ERP stands for exposure and response prevention. It is a common approach in therapy for OCD. The idea is simple, though doing it is hard. You deliberately face the feared situation (the exposure) and you stop yourself from doing the compulsion (the response prevention).
For checking OCD, an ERP exercise might look like this:
- You lock the front door once. You do not go back to check it.
- You feel the anxiety rise. You sit with it. You do not check.
- The anxiety will peak and then come down on its own, usually within 20 to 30 minutes.
- You repeat this so your brain learns that nothing bad happens when you do not check.
The exposure does not have to be real. You can do it in imagination. You can do it with a therapist guiding you. The key is that you prevent the response. You do not check, and you do not seek reassurance.
For a full guide on how this works, see ERP therapy for OCD: how exposure and response prevention works.
Practical things you can try
ERP is often done with a therapist, but there are small steps you can start on your own.
- Notice the checking. Keep a simple log for a few days. What are you checking? How many times? What do you feel right before you check?
- Delay the check. If you feel the urge to check, tell yourself you will wait five minutes. Then ten. Then fifteen. Often the urge fades.
- Reduce the number of checks. If you usually check the door three times, try checking it twice. Then once. Then not at all.
- Stop asking for reassurance. This is hard, but you can tell the person you usually ask: "I am working on my OCD. Please do not answer if I ask you to check something for me."
- Use a hierarchy. Start with something that feels easier to resist, not the hardest thing. Build up gradually.
A temple committee member in Leicester might start by sending one email without re-reading it. He feels the anxiety, but he lets the email go. The next day, nothing bad has happened. He tries again with a longer message. Over weeks, the anxiety shrinks.
When and how to get professional help
You do not have to do this alone. Many people find that checking OCD gets worse over time if left untreated. A therapist who works with OCD can help you design an ERP plan that fits your life. They can also help with the underlying beliefs that feed the OCD, such as the idea that you must be completely certain about everything, or that a mistake would be catastrophic.
You can start by talking to your GP or family doctor. They can refer you to a specialist. You can also look for therapists who list OCD as a specialty. Therapy O'Clock has a professionals directory where you can find therapists who work online, which can be useful if you live far from services.
For some people, medication can also help reduce the intensity of the anxiety, making the ERP work more manageable. A doctor can talk through the options. You can read more about this in What Helps for OCD: Therapy and Medication Basics.
If faith is important to you, you might worry that treatment conflicts with your beliefs. Many therapists are experienced in working with people of faith. There is also a page specifically about this: Faith and OCD treatment: getting help without losing your deen.
What recovery looks like
Recovery from checking OCD does not mean you will never check anything again. Everyone checks things sometimes. Recovery means the checking is a choice, not a compulsion. You can decide to check the door once, and then walk away without the anxiety chasing you.
It takes time. There will be good days and bad days. The goal is not perfection. The goal is to live your life without the OCD running it.
Questions people ask
Is checking OCD the same as being careful?
No. Being careful is a choice. Checking OCD feels like you have no choice. The urge to check is driven by anxiety and doubt, not by a sensible decision. The checking is also repeated, and it does not settle the doubt.
Why do I still feel doubt even after I check?
The doubt in OCD is not based on evidence. It is a brain signal that keeps firing. Checking does not fix the signal. It only gives you a few seconds of relief before the signal starts again.
Can checking OCD get worse over time?
Yes. The more you check, the more your brain learns that checking is necessary. The anxiety and doubt can grow. This is why treatment focuses on stopping the checking, not on getting better at it.
What if I stop checking and something bad really happens?
This is the fear at the heart of the OCD. In ERP, you learn to tolerate the risk that something could go wrong, just like everyone else does. The goal is not zero risk, but living with ordinary uncertainty.
Is reassurance-seeking a form of checking?
Yes. Asking someone else to confirm that something is okay works the same way as checking it yourself. It gives temporary relief and strengthens the OCD cycle.
Can ERP be done without a therapist?
You can try small exercises on your own, but ERP is most effective with a therapist who can guide you through the hierarchy of fears and help you stay on track. It is hard to do alone.
How long does ERP take to work?
Some people notice a difference in a few weeks. For others, it takes months. The key is consistency. Doing small exposures regularly is more helpful than big ones done rarely.
Is checking OCD related to contamination OCD?
They are different patterns, but they share the same OCD cycle. Contamination OCD focuses on fear of dirt or germs, while checking OCD focuses on fear of mistakes. You can read about the other pattern in Contamination OCD: Fear and Cleaning.
What if I check my thoughts or memories?
This is a form of mental checking. You might go over a memory again and again to see if it is accurate. Mental checking works the same way as physical checking and can be treated with the same ERP approach.
Can children have checking OCD?
Yes. Children can show the same patterns, sometimes around homework, bedtime routines, or checking on family members. Treatment for children uses the same principles but is adapted to their age.
Does OCD ever go away completely?
For many people, the symptoms become much quieter with treatment. The OCD may never vanish, but it stops controlling your life. You learn to manage it so it takes up very little space.
What if I live in a country with few mental health services?
Online therapy can help. You can also use self-guided ERP resources. The Find A Helpline website lists helplines by country, and organisations like OCD-UK offer information and support.
