To assess the level of agreement between the Subjective Frailty Assessment (SFA) and Clinical Functional Vulnerability Index (CFVI-20) for the diagnosis of frailty in older adults.
A descriptive, comparative, cross-sectional study was conducted in 2018/2019 with 492 older adults at nine Family Health Strategy units in the city of Três Lagoas, state of Mato Grosso do Sul, Brazil. Frailty was assessed using the SFA and CFVI-20 in addition to a structured interview. The Wilcoxon test and Pearson's chi-squared test were used for the comparisons.
Agreement was 35.4%, with a Kappa coefficient of 0.11. After dichotomizing the sample into frail and non-frail individuals, agreement was 70.1%, with a Kappa coefficient of 0.41 and Cronbach's alpha coefficients of 0.61 and 0.74 for IVCF-20 and SFA, respectively. The prevalence of frailty was lower using the IVCF-20 (17.1%) compared to 59.8% using the SFA.
Agreement regarding the classification of frailty between the two instruments ranged from low to moderate. This finding underscores the need for a standardized instrument for measuring frailty in community-dwelling older adults.
评估主观脆弱性评估（SFA）与临床功能脆弱性指数（CFVI-20）在诊断老年人脆弱性方面的一致性水平。
2018/2019 年，巴西南马托格罗索州特雷斯拉戈斯市的 9 个家庭健康战略单位进行了一项描述性、比较性、横断面研究，共纳入 492 名老年人。采用 SFA 和 CFVI-20 以及结构化访谈评估脆弱性。采用 Wilcoxon 检验和 Pearson 卡方检验进行比较。
一致性为 35.4%，Kappa 系数为 0.11。将样本分为脆弱组和非脆弱组后，一致性为 70.1%，Kappa 系数为 0.41，IVCF-20 和 SFA 的 Cronbach's alpha 系数分别为 0.61 和 0.74。使用 IVCF-20 时，脆弱性的患病率较低（17.1%），而使用 SFA 时则为 59.8%。
两种工具在脆弱性分类方面的一致性程度从低到中等不等。这一发现强调了需要一种标准化的工具来衡量社区居住的老年人的脆弱性。
