Exploring Self-Perception Bias of Fall Risk and Its Influencing Factors in Older Adults
This cross-sectional study of 8,195 older adults reveals that approximately 31% exhibit a discrepancy between their subjective and objective fall risk, with overestimation linked to female gender and psychological distress, while underestimation is associated with male gender and poorer physical mobility, highlighting the need for targeted, multidimensional fall prevention interventions.

Falling is a universal fear for older adults, often triggering a cycle where the worry of falling leads to less movement, which in turn makes the body weaker and the fall more likely. For this reason, doctors and researchers have long tried to understand how well people can judge their own safety. The core idea is simple: if an older person knows they are at risk, they might take steps to stay safe, like using a cane or removing loose rugs. But if they think they are safe when they are not, they might ignore warning signs. Conversely, if they are afraid of falling when they are actually steady, they might stop moving altogether, which creates a different kind of danger. The question researchers have struggled with is not just whether people are wrong about their risk, but in which direction they are wrong, and why.
A team of researchers at the Chinese PLA Medical School and the Chinese PLA General Hospital set out to solve this puzzle by looking at a massive group of older adults. They gathered 8,195 people, all aged 60 or older, who had visited a specialized clinic designed to prevent falls. The team wanted to see if these individuals could accurately match their own feelings of safety with their actual physical abilities. To do this, they used two different tools. First, they asked the participants to fill out a questionnaire about their own worries, their history of falling, and how they felt about their balance. This gave the researchers a picture of what the people thought about their risk. Second, they put everyone through a simple physical test called the Timed Up and Go. In this test, a person stands up from a chair, walks three meters, turns around, walks back, and sits down again. The time it takes to complete this task is a reliable measure of how steady and mobile a person really is. By comparing the answers on the questionnaire with the time on the stopwatch, the researchers could see who was accurate, who was too worried, and who was too confident.
The results revealed that about one-third of the people in the study had a mismatch between their feelings and their reality. This group was split almost evenly between those who overestimated their danger and those who underestimated it. The people who thought they were in more danger than they actually were tended to be women, had higher levels of education, and reported feeling more anxious or depressed. They also experienced more sudden, episodic symptoms like dizziness when standing up or low blood sugar. These individuals often had excellent physical balance, finishing the walking test very quickly, yet they still felt unsafe. On the other side of the spectrum were the people who underestimated their risk. This group was more likely to be men, have less education, and report feeling psychologically well. However, their physical test results told a different story: they took significantly longer to complete the walking task, indicating they were physically more vulnerable to falling, even though they felt fine.
The study found that the physical speed of walking was the strongest clue for understanding which way a person's bias would lean. For those who moved quickly, the faster they were, the more likely they were to overestimate their risk. For those who moved slowly, the slower they were, the more likely they were to underestimate their risk. This suggests that the body's actual performance plays a central role in how the mind interprets safety, but it does so in opposite ways depending on the person. The researchers also used advanced computer models to confirm these findings, which showed that the time it took to walk the short distance was the single most important factor in predicting whether someone would be an over-worrier or an over-confident risk-taker. Age and feelings of depression also played significant roles, but the physical test remained the most powerful indicator.
These findings suggest that a single approach to fall prevention will not work for everyone. The study argues that doctors need to look at the whole person, not just their physical strength. For the women who are physically strong but feel afraid, the solution might involve addressing their anxiety and helping them trust their bodies again. For the men who are physically weak but feel confident, the solution might involve showing them concrete evidence of their slowness and helping them build strength. The researchers emphasize that understanding the direction of the bias—whether a person is too scared or too careless—is essential for creating the right kind of help. By recognizing that these two groups have very different backgrounds, moods, and physical traits, healthcare providers can move away from a one-size-fits-all approach and offer targeted support that helps older adults find a balance between safety and confidence.
