To cross-culturally adapt and validate the Comprehensive Frailty Assessment Instrument (CFAI) among Chinese community-dwelling older adults.
The Chinese CFAI was developed through forward-backward translations. An urban sample of 1235 community-dwelling older adults received face-to-face interviews to examine the validity (construct validity and criterion validity) and reliability (internal consistency and test-retest reliability).
The Chinese CFAI achieved semantic and idiomatic equivalence, and showed acceptable reliability and an expected factor structure, except for the social support domain. The exploratory factor analysis extracted five factors explaining 53.8% of the total variance of frailty. The confirmatory factor analysis showed that the data fit well to the second-order factor theoretical model, with a root mean square error of approximation of 0.05, Tucker-Lewis Index of 0.93 and Comparative Fit Index of 0.95. The receiver operating characteristic analysis presented an acceptable criterion validity using the Rockwood Frailty Index as an external criterion (area under the curve 0.80), with balanced sensitivity (65.31%) and specificity (81.19%) at the optimal 39-point frailty cut-off of the CFAI.
The Chinese CFAI has good validity and reliability as a practical frailty measure in Chinese community-dwelling older adults. Geriatr Gerontol Int 2018; 18: 301-307.
跨文化调适和验证综合虚弱评估工具（CFAI）在中国社区居住的老年人中。
通过正向和反向翻译开发了中文 CFAI。对 1235 名居住在社区的老年人进行了面对面访谈，以检验其有效性（构念效度和标准效度）和可靠性（内部一致性和重测信度）。
中文 CFAI 实现了语义和习惯用法的等效性，具有可接受的可靠性和预期的因素结构，但社会支持领域除外。探索性因子分析提取了五个因素，解释了虚弱的总方差的 53.8%。验证性因子分析表明，数据与二阶因子理论模型拟合良好，逼近均方误差为 0.05，Tucker-Lewis 指数为 0.93，比较拟合指数为 0.95。使用 Rockwood 虚弱指数作为外部标准的受试者工作特征分析显示出可接受的标准效度（曲线下面积为 0.80），在 CFAI 的最佳 39 分虚弱切点处具有平衡的敏感性（65.31%）和特异性（81.19%）。
中文 CFAI 作为一种实用的中国社区居住老年人虚弱评估工具，具有良好的有效性和可靠性。老年医学杂志 2018; 18: 301-307.
