Development of a screening tool for risk of locomotive syndrome in the elderly: the 25-question Geriatric Locomotive Function Scale.

摘要

To evaluate the reliability and validity of a new questionnaire, the 25-question Geriatric Locomotive Function Scale (GLFS-25), for early detection of locomotive syndrome.This new screening tool was designed to detect Japanese individuals under high-risk conditions who may soon require care services because of problems of the locomotive organs. Content validity, construct validity, criterion validity, internal-consistency reliability, and reproducibility (test-retest reliability) were examined using psychometric analysis, and a cutoff score to detect locomotive syndrome was determined. To investigate construct validity of the GLFS-25 and determine the cutoff score, the Akaike Information Criteria (AIC) were used.Study 1 analyzed 711 Japanese elderly people ≥65?years old. No floor or ceiling effects were included in the GLFS-25. Internal consistency was confirmed by a Cronbach's α reliability coefficient of 0.961. As for the association between the GLFS-25 and European Quality of Life Scale-5 Dimensions (EQ-5D), Spearman's correlation coefficient was 0.85 (P?
