Abstract
Introduction
The Fried phenotype is one of the most commonly used scales for assessing frailty, although its implementation in clinical practice can be complex. A simplified and modified version has been developed in Turkey, and the aim of this study is to translate and validate it into Spanish.
Methods
A cross-sectional study was conducted with 100 participants. Internal consistency, inter-rater reliability, test-retest reliability, criterion validity (comparing the simplified and modified versions of Fried with the FRAIL scale), sensitivity, and specificity were evaluated.
Results
Inter-rater reliability and test-retest reliability were excellent (kappa indices of 0.83 and 0.86, respectively), while internal consistency was moderate (Cronbach's alpha of 0.67). Criterion validity was also moderate, with Cohen's kappa coefficients of 0.50 and 0.51 when compared to the modified version of Fried and FRAIL, achieving a sensitivity of 63% and a specificity of 89%.
Conclusions
The Spanish version shows excellent reliability but moderate internal consistency and validity, as well as low sensitivity. These limitations may hinder its utility in detecting frailty, potentially due to sample selection or cultural differences.
