The Iconographical Falls Efficacy Scale (Icon-FES) is an innovative tool to assess concern of falling that uses pictures as visual cues to provide more complete environmental contexts. Advantages of Icon-FES over previous scales include the addition of more demanding balance-related activities, ability to assess concern about falling in highly functioning older people, and its normal distribution.
To perform a cross-cultural adaptation and to assess the measurement properties of the 30-item and 10-item Icon-FES in a community-dwelling Brazilian older population.
The cross-cultural adaptation followed the recommendations of international guidelines. We evaluated the measurement properties (i.e. internal consistency, test-retest reproducibility, standard error of the measurement, minimal detectable change, construct validity, ceiling/floor effect, data distribution and discriminative validity), in 100 community-dwelling people aged ≥60 years.
The 30-item and 10-item Icon-FES-Brazil showed good internal consistency (alpha and omega >0.70) and excellent intra-rater reproducibility (ICC=0.96 and 0.93, respectively). According to the standard error of the measurement and minimal detectable change, the magnitude of change needed to exceed the measurement error and variability were 7.2 and 3.4 points for the 30-item and 10-item Icon-FES, respectively. We observed an excellent correlation between both versions of the Icon-FES and Falls Efficacy Scale - International (rho=0.83, p<0.001 [30-item version]; 0.76, p<0.001 [10-item version]). Icon-FES versions showed normal distribution, no floor/ceiling effects and were able to discriminate between groups relating to fall risk factors.
Icon-FES-Brazil is a semantically and linguistically appropriate tool with acceptable measurement properties to evaluate concern about falling among the community-dwelling older population.
Iconographical Falls Efficacy Scale（Icon-FES）是一种评估跌倒担忧的创新工具，它使用图片作为视觉提示，提供更完整的环境背景。与之前的量表相比，Icon-FES 的优势包括增加了更具挑战性的平衡相关活动、能够评估高功能老年人对跌倒的担忧，以及其正态分布。
对 30 项和 10 项 Icon-FES 进行跨文化调适，并评估其在巴西社区居住的老年人群中的测量特性。
跨文化调适遵循国际指南的建议。我们评估了测量特性（即内部一致性、重测信度、测量的标准误差、最小可检测变化、结构效度、天花板/地板效应、数据分布和判别效度），纳入了 100 名年龄≥60 岁的社区居住者。
30 项和 10 项 Icon-FES-Brazil 具有良好的内部一致性（alpha 和 omega>0.70）和极好的内部重测信度（ICC=0.96 和 0.93）。根据测量的标准误差和最小可检测变化，需要改变 7.2 点和 3.4 点才能超过测量误差和变异性，这对于 30 项和 10 项 Icon-FES 分别是需要改变的幅度。我们观察到两个版本的 Icon-FES 和 Falls Efficacy Scale-International 之间有极好的相关性（rho=0.83，p<0.001 [30 项版本]；0.76，p<0.001 [10 项版本]）。Icon-FES 版本显示正态分布，无地板/天花板效应，能够区分与跌倒危险因素相关的组。
Icon-FES-Brazil 是一种语义和语言上合适的工具，具有可接受的测量特性，可用于评估社区居住的老年人群对跌倒的担忧。
