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.
更简单的修改Fried虚弱量表:西班牙语翻译和验证
Fried表型是最常用的评估虚弱的量表之一,尽管它在临床实践中的实施可能是复杂的。土耳其已经开发了一个简化和修改的版本,本研究的目的是将其翻译并验证为西班牙语。方法采用横断面研究方法,纳入100例受试者。评估了内部一致性、量表间信度、重测信度、标准效度(将Fried量表的简化版和修改版与脆弱量表进行比较)、敏感性和特异性。结果量表的内部信度和重测信度较好(kappa指数分别为0.83和0.86),内部信度为中等(Cronbach’s alpha为0.67)。标准效度也中等,与改良版的Fried和weak相比,Cohen的kappa系数分别为0.50和0.51,灵敏度为63%,特异性为89%。结论西班牙语版本具有良好的信度,但内部一致性和效度一般,敏感性较低。这些限制可能会阻碍其在检测脆弱方面的效用,可能是由于样本选择或文化差异。
