It’s common to double-check things from time to time—making sure the stove is off or the door is locked. It’s natural to want that reassurance. But for some, these behaviors become extreme, constant, and compulsive, reinforcing an exhausting cycle that’s hard to break.
Maybe you’re out with friends when a nagging thought hits: Did I lock my car? Did I pack everything I need? Even if you remember doing it, you second-guess yourself. You find yourself stepping away just to check your car or repack your bag over and over, never quite sure you got it right.
If this sounds familiar, you might be experiencing checking OCD—a form of obsessive-compulsive disorder (OCD) that fuels persistent doubts and the urge to check, even when there’s no logical reason to do so.

What is checking OCD?
OCD is a mental health condition marked by intrusive thoughts, feelings, urges, images, and sensations that cause distress. In an attempt to find relief, people with OCD engage in compulsions—repetitive behaviors or mental rituals meant to ease anxiety.
Checking OCD is a specific subtype of OCD, where intrusive thoughts create intense doubt and fear—often centered around the possibility of causing harm, making a mistake, or being responsible for something bad happening. To manage this distress, you might feel compelled to check your past actions, even when there’s no obvious reason to do so.
Experts say the lengths people go to in order to check vary from person to person. “Some people are satisfied by reassurance from someone else—for instance, your husband telling you that you turned off all the lights before you left home,” says Gary VanDalfsen, PhD. “Others need visual confirmation, like driving home from the office in the middle of the workday to check for themselves.”
These compulsions may provide temporary relief, but that relief is fleeting, strengthening anxiety and reinforcing the urge to check again.
What causes checking OCD?
There’s no single cause of checking OCD, but a combination of neurobiological, genetic, cognitive, behavioral, and environmental factors play a role. While researchers are still learning more about what leads to OCD in some people and not others, we do know what perpetuates the symptoms.
Compulsions, like checking, provide temporary relief from anxiety. Because that relief feels reassuring in the moment, the brain learns to rely on it as a way to ease doubt. “This becomes a closed loop in which the person with OCD gets trapped, never learning that there is another way out,” explains Dr. VanDalfsen. The more someone checks, the stronger the habit becomes, making it even harder to resist compulsion in the future.
Signs and symptoms of checking OCD
If you have checking OCD, you probably experience significant concerns about bad things happening—either to yourself or others—and you may feel an overwhelming sense of responsibility.
“These obsessive concerns create intense distress, usually in the form of anxiety,” explains Dr. VanDalfsen. In response, people engage in checking to try to gain certainty that these feared outcomes haven’t happened—or won’t happen.
| Common Checking OCD Obsessions | Common Checking OCD Compulsions |
| Safety: Fear of causing harm, such as starting a fire, flooding or burglary. | Physical inspection: Closely examining objects, rechecking locks, appliances, or documents; taking photos for proof. |
| Health: Worrying about developing a serious illness or infecting someone else. | Reassurance seeking: Asking others to confirm you haven’t made mistakes; repeating reminders out loud. |
| Mistakes: Fear of making errors, no matter how small. | Mental rituals: Replaying past events in your mind to try to gain certainty that nothing bad has happened. |
| Inappropriate behavior: Excessive worry about unintentionally saying or doing something offensive. | Avoidance: Avoiding situations where mistakes might happen, like asking a partner to lock up for you or avoiding important conversations. |
Is checking OCD treatable?
The good news is that checking OCD, like all forms of OCD, is highly treatable. The most effective, evidence-based treatment is a specialized form of cognitive behavioral therapy (CBT) called exposure and response prevention (ERP) therapy.
ERP is a proven, evidence-based approach that helps you gradually face your fears through exposure exercises, while learning techniques to resist the urge to engage in compulsions. Rather than relying on checking or reassurance seeking to ease your anxiety, ERP teaches you how to tolerate uncertainty. “ERP teaches people that they can handle uncertainty and that their anxiety will subside on its own,” explains Dr. VanDalfsen.
What does ERP look like for checking OCD?
Imagine your checking OCD makes you consistently late to work. You wake up early, get ready, but as you approach the door, intrusive thoughts flood your mind. You can’t remember if you turned off your stove and are gripped by a fear of starting a fire. The doubt is unbearable, so you go back to check–losing precious time and ending up late for work.
In ERP, your therapist would guide you to practice leaving your home without checking, even though it feels uncomfortable. At first, your anxiety might spike, and the urge to check will feel overwhelming. But, instead of giving in, you’d sit with the discomfort and let it pass. With time and repetition, your brain will learn that resisting the compulsion doesn’t lead to disaster. In fact, you may even find the distress passes sooner than you expected.
ERP doesn’t eliminate intrusive thoughts, but it helps you to stop wasting time on compulsions. It teaches you that you’re stronger than you think, and that you don’t need to check to feel safe or certain enough to go about your day.
Bottom line
Checking OCD can make daily life feel exhausting, turning simple tasks into rituals that take hours to complete. But, effective treatment is available. ERP therapy helps you break free from the checking cycle by teaching you that you don’t need compulsions to feel safe. While facing uncertainty can feel difficult at first, recovery is possible with the right support. If checking rituals are taking over your life, consider reaching out for professional help. You deserve to reclaim your time, energy, and confidence without getting stuck in the checking cycle.
