Safety checking

What is it?

Safety checking is repeated checking behavior meant to reduce anxiety or prevent something from going wrong. This can look like rereading messages, checking locks, looking up symptoms, confirming plans, reviewing work, monitoring tone, or repeatedly making sure you didn’t make a mistake. Checking can be useful once or twice, but when it becomes compulsive, it teaches the brain that uncertainty is dangerous and must be neutralized. The more you check, the less you may trust your own memory, judgment, or ability to handle uncertainty.

How do people work on it?

Safety checking becomes a problem when checking no longer gives you trustworthy information and instead feeds doubt. The way to work on it is to separate reasonable checking from anxiety checking. Reasonable checking is limited and functional: checking the stove once before leaving. Anxiety checking is repetitive and driven by the feeling that you need to be absolutely sure. A good first step is to create a rule before anxiety spikes, like: “I check once, slowly and deliberately, then I leave.” The point is to make checking conscious and bounded rather than automatic.

A useful exercise: practice single-checking. When you check something, narrate it clearly: “The door is locked.” Then walk away without rechecking. If anxiety rises, treat that as the practice, not as a sign you need to go back. You’re teaching your brain that the feeling of doubt doesn’t require another check.

Additional resources to explore: CBT with exposure and response prevention principles can be useful when checking is repetitive or compulsive. If checking is severe, time-consuming, or tied to intrusive thoughts, it may be worth exploring OCD-informed CBT/ERP with a clinician.
