Turkish Version of Lower Extremity Functional Scale in Elders

September 12, 2021 updated by: Güzin Kara, Pamukkale University

Validity and Reliability of Turkish Version of Lower Extremity Functional Scale in Elders

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lower Extremity Functional Scale
Time Frame: 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.
seven days
Five-Times-Sit-to-Stand Test
Time Frame: 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.
seven days
Falls Efficacy Scale International
Time Frame: 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).
seven days
