Cross-Cultural Adaptation and Validation of the Balance in Daily Life Scale in Frail Older Adults: A Turkish Study
This study successfully validated the Turkish version of the Balance in Daily Life Scale for frail older adults, confirming its original unidimensional structure and demonstrating high reliability and validity for assessing balance in daily activities within this population.

As people grow older, their bodies undergo a quiet but profound shift. Muscles weaken, senses dull, and the delicate internal systems that keep a person upright become less resilient. For many, this leads to a state known as frailty, where even a small challenge can disrupt their daily life. In this vulnerable period, the ability to maintain balance is not just a physical skill; it is the foundation of independence. Without it, simple acts like walking to the kitchen or turning in a chair become dangerous, leading to falls, fear, and a loss of freedom. While doctors and therapists have long used various tools to measure how well a person stands or walks, there has been a gap in Turkey: no specific, reliable way to measure how frail older adults actually manage their balance during the routine tasks of their everyday lives.
To fill this gap, a team of researchers in eastern Turkey set out to adapt a new measurement tool for their local population. They focused on a scale called the Balance in Daily Life Scale, which was originally developed to test how well people handle seven specific, common activities. The goal was not to invent a new test, but to translate and verify the existing one so it would work perfectly for Turkish speakers who are frail. The researchers gathered a large group of 330 older adults, all aged 65 or older, who were already receiving care at a hospital for physical therapy. These participants were carefully chosen to ensure they were frail but still able to understand instructions and move around with or without a walking aid.
The process began with a careful translation of the scale from English into Turkish. Two language experts translated the questions, and a panel of ten specialists, including doctors and nurses, reviewed the new version to ensure the words made sense culturally and linguistically. They checked that every item was clear and relevant, making only minor tweaks to improve the flow of language without changing the meaning. Once the Turkish version was ready, the researchers put it to the test. They asked the 330 participants to perform the seven daily-life tasks, such as sitting, standing, and walking, while the researchers scored their performance. To see if the results were consistent over time, a smaller group of 30 people repeated the test two weeks later.
The results showed that the Turkish version of the scale worked exactly as the original did. The data confirmed that the seven items measured a single, unified concept of balance in daily life, just as the creators of the original scale intended. The questions were all strongly connected to the overall score, meaning each task provided valuable information about a person's stability. When the researchers looked at how well the scores held up over the two-week period, they found them to be remarkably stable; a person who scored well on the first day scored well on the second, and the scores did not drift or change randomly. The internal consistency was also very high, indicating that the questions worked together as a cohesive whole to tell a clear story about a person's balance.
This study proves that the Turkish version of the Balance in Daily Life Scale is a trustworthy tool for doctors and researchers in Turkey. It offers a practical way to assess how frail older adults are managing their movement in the real world, rather than just in a clinic setting. By confirming that the scale is valid and reliable, the researchers have provided healthcare professionals with a new way to identify those at risk and plan better rehabilitation. The tool is now ready to be used to help protect the independence of frail older adults, ensuring that their daily lives remain safe and supported.
