BACKGROUND
The Falls Efficacy Scale-International (FES-I) is a commonly used questionnaire to evaluate concerns about falling. We adapted a Taiwan Chinese version (FES-I) and evaluated its reliability and validity in community-dwelling elderly individuals. The discriminative validity was tested in relation to several known risk factors for fear of falling (FOF).
METHODS
The questionnaire was adapted through translation, back-translation, and expert review processes. A convenience sample of 135 community-dwelling elderly individuals (at least 60 years old) completed the adapted questionnaire, and 31 of them had a retest within 7-10 days. Cronbach's α and an intraclass correlation coefficient (ICC) were used to evaluate the internal consistency and test-retest reliability. Principal component factor analysis was performed to assess the factor-construct validity. The discriminative validity was tested in relation to demographic features, fall-related history and performances on three functional tests: timed up and go, four-stage balance and 30-s chair stand tests. Effect sizes were computed. Correlation coefficients between physical functional performance and FES-I scores were computed. Receiver operating characteristic curves were used to determine the cutoff point for the score to differentiate high and low concern of falling.
RESULTS
The FES-I questionnaire had high internal consistency (Cronbach's α = 0.94) and excellent test-retest reliability (ICC = 0.94). Principal component factor analysis yielded a two-factor model, with several items requiring high demand on postural control loading on factor 2. FES-I scores discriminated individuals with different ages, reporting FOF, reporting falls in the past year and using walking aids. However, FES-I scores did not differ between the participants who were at risk of falling and those who were not at risk based on functional test performance and there was no correlation found between them.
CONCLUSION
The FES-I was highly reliable and had adequate construct and discriminative validity. The lack of correlation between FES-I scores and functional test performance implied the presence of FOF even in individuals with good functional performance. Further follow up studies are warranted to verify the predictive validity of the FES-I.
背景
国际跌倒效能量表（FES-I）是一种常用于评估跌倒担忧的问卷。我们对其进行了繁体中文版改编（FES-I），并在社区居住的老年人中评估了其信度和效度。鉴别效度与跌倒恐惧（FOF）的几个已知危险因素相关进行了测试。
方法
通过翻译、回译和专家审查过程对问卷进行了改编。一个方便样本的 135 名社区居住的老年人（至少 60 岁）完成了改编后的问卷，其中 31 名在 7-10 天内进行了重测。Cronbach's α 和组内相关系数（ICC）用于评估内部一致性和重测信度。主成分因子分析用于评估因子结构效度。鉴别效度与人口统计学特征、跌倒相关史以及三项功能测试（计时起身行走、四阶段平衡和 30 秒椅站测试）的表现相关进行了测试。计算了效应量。计算了身体功能表现与 FES-I 评分之间的相关系数。使用受试者工作特征曲线确定区分高、低跌倒担忧得分的截断点。
结果
FES-I 问卷具有较高的内部一致性（Cronbach's α=0.94）和极好的重测信度（ICC=0.94）。主成分因子分析产生了一个两因素模型，几个对姿势控制要求较高的项目在因素 2 上加载。FES-I 评分可区分不同年龄、报告 FOF、报告过去一年跌倒和使用助行器的个体。然而，FES-I 评分在功能测试表现存在风险和无风险的参与者之间没有差异，且它们之间没有相关性。
结论
FES-I 具有较高的可靠性，且具有足够的结构和鉴别效度。FES-I 评分与功能测试表现之间缺乏相关性意味着即使在功能表现良好的个体中也存在 FOF。需要进一步的随访研究来验证 FES-I 的预测效度。
