简要总结
This study was conducted in order to analyze the validity and reliability, and psychometric properties of the Turkish version of the Lower Extremity Functional Scale (LEFS-T) in elder adults. The LEFS was translated and cross-culturally adapted to Turkish. Totally 214 elders were included in the study. The LEFS-T, Five-Times-Sit-to-Stand Test (FTSTS), and Falls Efficacy Scale International (FES-I) were applied to all older adults. Item-total correlations of factors and Cronbach alpha internal consistency coefficients were determined to examine the reliability. The relationship between the LEFS-T, FTSTS, and FES-I was analyzed. Exploratory (EFA) and confirmatory factor analysis (CFA) were used for construct validity. Spearman Correlation Analysis was used for concurrent validity. Davis technique was used to calculate the content validity index. Floor and ceiling effect were calculated. It has been concluded that the LEFS-T has good psychometric qualities and can be recommended as a choice of measurement tool to assess self-reported physical functioning in elder adults.

结局指标
主要结局
Five-Times-Sit-to-Stand Test
时间窗: seven days
The elders were instructed to stand from a standard chair five consecutive times as fast as possible.The duration of the test was recorded in terms of seconds. Less duration means better performance.
Lower Extremity Functional Scale
时间窗: seven days
The Lower Extremity Functional Scale was translated and cross-culturally adapted to Turkish. Items are scored as a 5-point Likert Scale (0 = extreme difficulty/ unable to perform an activity, 4 = no difficulty). The highest total score of 80 indicates that the person has a high functional level.
Falls Efficacy Scale International
时间窗: seven days
The Prevention of Falls Network Europe developed the Falls Efficacy Scale International to assess people's fear of falling during daily living activities. The items score between 1 (not at all concerned) to 4 (very concerned).
