方法：在基线和12个月时，对500名社区居住的老年人（70-90岁）进行了FES-I评估，并结合人口统计学、生理学和神经心理学测量。结果：两个量表的整体结构和测量性能，项目反应理论评价，是良好的。在基线（n = 500，收敛有效性）和1年随访（n = 463，预测有效性）时，生理和神经心理学测量的辨别能力显示出良好的有效性。纵向随访表明，无论是否发生跌倒事件，FES-I评分均随时间推移而增加，当一个人在3个月内遭受多次福尔斯跌倒时，FES-I评分有更强的增加趋势。此外，使用受试者工作特征（ROC）曲线，临界点被定义为区分较低和较高的水平的concerns.Conclusions：目前的研究建立在以前建立的心理特性的FES-I。两种量表具有可接受的结构，良好的效度和信度，可以推荐用于研究和临床目的。未来的研究应探讨FES-I对干预研究期间变化的反应，并确认在其他环境、更大样本和不同文化中建议的临界点。
Method: five hundred community-dwelling older people (70-90 years) were assessed on the FES-I in conjunction with demographic, physiological and neuropsychological measures at baseline and at 12 months. Falls were monitored monthly and fear of falling every 3 months.Results: the overall structure and measurement properties of both FES-I scales, as evaluated with item response theory, were good. Discriminative ability on physiological and neuropsychological measures indicated excellent validity, both at baseline (n = 500, convergent validity) and at 1-year follow-up (n = 463, predictive validity). The longitudinal follow-up suggested that FES-I scores increased over time regardless of any fall event, with a trend for a stronger increase in FES-I scores when a person suffered multiple falls in a 3-month period. Additionally, using receiver-operating characteristic (ROC) curves, cut-points were defined to differentiate between lower and higher levels of concern.Conclusions: the current study builds on the previously established psychometric properties of the FES-I. Both scales have acceptable structures, good validity and reliability and can be recommended for research and clinical purposes. Future studies should explore the FES-I's responsiveness to change during intervention studies and confirm suggested cut-points in other settings, larger samples and across different cultures.
