How to do it
- Name the question you keep asking. Write it down once.
- Pick one check that can actually settle it, a doctor's appointment or one straight conversation. Not a search, not a friend's guess.
- Do the check, then stop. When the urge to ask again comes, the answer is that it's been checked.
- New information is different. A symptom that persists, gets worse or changes goes back to the doctor.
How checking keeps going
- Doubthard to sit with
Across many studies, finding uncertainty hard to bear went with worry and anxiety. A snapshot, so it doesn't show which comes first.
- Asking againgoes with low mood
Across 38 studies, people who kept seeking reassurance had more depression at the same time. Which drives which isn't shown.
- Other peoplecan pull away
In 16 studies, reassurance-seeking also went with more rejection, often as the person reported it. A small link, and a snapshot too.
- Youone check, then stop
Swapping repeat checks for one proper one is my suggestion. Nobody has tested it.
Why it works
When something nags at you, a symptom, a short reply from a friend, whether things are fine with your partner, the pull is to check again. Google again. Ask again. Across 38 studies and 6,973 people, people who kept seeking reassurance had more depression. Evidence: decent Those were snapshots, so it's a link: low mood could drive the asking as much as the other way round. Evidence: decent
One proper check, then stop, is my way of cutting the loop. It's the same idea as three checks, not three hundred: fixed checks, not every pull. Nobody has tested it for reassurance. Evidence: worth trying

Doubt is hard to sit with. A meta-analysis, which pools many studies, found that intolerance of uncertainty, finding not-knowing hard to bear, went with symptoms of generalised anxiety, the worry-about-everything kind, and of depression and obsessive-compulsive disorder, at similar strength. Evidence: decent Snapshot data again. Evidence: decent
Asking again goes with low mood. Across 38 studies, excessive reassurance-seeking correlated .32 with depression measured at the same time. On a scale where 0 is no link and 1 is a perfect one, that's moderate. Evidence: decent
Other people can pull away. Across 16 studies, it also went with more rejection, a small link of .14. Evidence: decent The link was stronger when the person reported the rejection than when others did. Evidence: decent
You check once, then stop. Swapping repeat checks for one proper one is my suggestion. The studies didn't test stopping. Evidence: worth trying
Searching symptoms online has its own name, cyberchondria, and a questionnaire built to measure it. Evidence: solid A study that followed 5,322 people over four surveys found health-anxious people searched more, with early signs that the searching and the worry feed each other. Evidence: decent That held for people below clinical levels of health anxiety, not for those above. Evidence: decent
The proof
- Starr and Davila, 2008: a meta-analysis of 38 studies, 6,973 people. Excessive reassurance-seeking went with depression at the same time, r = .32. Evidence: decent The link was stronger in samples with more women. Evidence: decent Across 16 studies, it went with more rejection, r = .14. Evidence: decent Correlational, measured at one point in time. Evidence: decent
- Gentes and Ruscio, 2011: a meta-analysis linking intolerance of uncertainty with generalised anxiety, depression and obsessive-compulsive symptoms, at similar strength for all three. Evidence: decent
- te Poel et al., 2016: 5,322 people, four surveys. Health-anxious people searched more online; searching and health worry fed each other in people below clinical levels. The authors call it initial evidence. Evidence: decent
- McElroy and Shevlin, 2014: a questionnaire for measuring cyberchondria. Evidence: solid

Watch out
The reassurance studies are snapshots. They show constant checking goes with low mood, not that it causes it, or that stopping helps. Evidence: decent The one-check rule is my suggestion and untested. Evidence: worth trying
This is about asking again after you've had an answer. It's not a reason to skip care. A symptom that persists, gets worse or changes goes to a doctor, as often as that takes. If your mood has been low for a couple of weeks, start with two questions, then a doctor. If the checking is taking hours of your day, that's worth a doctor too.
Doubt about a partner that keeps coming back isn't fixed by discipline. It needs one real conversation. If it still keeps coming back after that, find someone outside it to talk it through with.
