INTRODUCTION
Geriatric Locomotive Function Scale-25 (GLFS-25) is a 25-item tool most commonly used to diagnose locomotive syndrome in the elderly. The purpose of the present study was to investigate the validity and reliability of the GLFS-25 questionnaire using factor analysis.
MATERIALS AND METHODS
This descriptive-analytical study was conducted on 186 elderly people. The GLFS-25 questionnaire contains 25 items, and each item is scored on a five-point Likert scale from 0 to 4. Data were analyzed by SPSS V.19 software. Descriptive (frequency, percentage, mean, and standard deviation) and inferential (Cronbach's alpha, correlation coefficient, Bartlett test, KMO index, scree plot, and factor analysis) statistics were used to present the findings.
RESULTS
Factor analysis revealed two hidden factors in the four dimensions of the questionnaire (i.e., pain, daily activities, social relations, and mental health). The first factor, named mobility and its consequential concerns), with a variance percentage of 74.323, had an effect on questions No. 19, 11, 25, 16, 6, 24, 5, 4, and 3. The second factor, named the problems and risks associated with daily and social activities, with a variance percentage of 78.680, had an effect on questions No. 17, 22, 7, 18, 14, 20, 13, 9, 12, 8, 10, 21, 2, 15, 1, and 23. Cronbach's alpha coefficient among the questionnaire's dimensions was 78.4%.
CONCLUSION
The GLFS-25 questionnaire can be used as a valid and reliable tool to diagnose locomotive syndrome in the elderly.
引言
老年运动功能量表-25（GLFS-25）是一个包含25个条目的工具，最常用于诊断老年人的运动综合征。本研究的目的是通过因子分析来探究GLFS-25问卷的有效性和可靠性。
材料与方法
本描述性分析研究针对186名老年人开展。GLFS-25问卷包含25个条目，每个条目采用从0到4的五点李克特量表进行评分。数据通过SPSS V.19软件进行分析。描述性统计（频率、百分比、均值和标准差）和推断性统计（克朗巴哈系数、相关系数、巴特利特检验、KMO指数、碎石图和因子分析）用于呈现研究结果。
结果
因子分析揭示了问卷四个维度（即疼痛、日常活动、社会关系和心理健康）中的两个潜在因子。第一个因子名为“ mobility and its consequential concerns”，方差百分比为74.323，对第19、11、25、16、6、24、5、4和3题有影响。第二个因子名为“日常和社会活动相关的问题和风险”，方差百分比为78.680，对第17、22、7、18、14、20、13、9、12、8、10、21、2、15、1和23题有影响。问卷各维度间的克朗巴哈系数为78.4%。
结论
GLFS-25问卷可作为诊断老年人运动综合征的有效且可靠的工具。
