Abstract
ABSTRACT Due to the need for a validated and relevant scale for assessing frailty, we aimed to translate and adapt a specific tool, ‘Edmonton Frail Scale’ (EFS), into the Persian language and evaluate its psychometric properties. In this methodological and cross-sectional study, we recruited 347 older adults in Naqadeh, Iran. Next, by using the Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), we examined the construct validity of the p-EFS. The internal consistency/reliability was estimated by computing Cronbach’s coefficient alpha. The Exploratory factor analysis revealed a three-factor model that included 11 items and accounted for 49.00% of the variance. Additionally, the construct validity of this three-factor model was supported by the results of the confirmatory factor analysis. The remerged factors were 1) functional, physiological, and cognition status, 2) medication, nutrition status, and social support, and 3) general health status. The Iranian version of EFS is a valid and reliable scale that we suggest for specialists, physicians, and health workers to measure frailty.
