Fear of falling may be related to falling during stroke onset. The Fall Efficacy ScaleInternational (FES-I) with excellent psychometric properties, is an instrument developed to assess patients' concerns about fallings. The aim of this study was to determine validation of this scale in Iranian patients with stroke.
The "forward-backward" procedure was applied to translate the FES-I from English to Persian. One hundred-twenty patients who had suffered stroke, aged 40 to 80 years (55% male) completed the Persian FES-I, Geriatric Depression Scale-15 (GDS-15), General Health Questionnaire-28 (GHQ-28), Berg Balance Scale (BBS) and Timed up and Go (TUG) questionnaires. The interval time for the test-retest of the Persian scale was 7-14 days.
The test-retest and inter-rater reliabilities of the Persian FES-I were excellent (ICC2,1=0.98, p<0.001) and the internal consistency was high (Cronbach's alpha=0.78). Factor analysis of the 16 items in the Persian scale showed only one significant factor. The total Persian FES-I score had a significantly negative correlation (p<0.001) with the BBS, but it had significantly positive correlation with the TUG, GHQ-28, and GDS-15. The difference in responsiveness scores across fallers and non-fallers yielded a large effect size (0.46), which indicated a good discriminating validity.
The Persian FES-I proved to be an effective and valuable measurement tool to assess stroke patients' fear of falling in practice and research setting.
对跌倒的恐惧可能与中风发作时的跌倒有关。国际跌倒效能量表（FES-I）具有出色的心理测量特性，是一种用于评估患者对跌倒担忧的工具。本研究的目的是确定该量表在伊朗中风患者中的有效性。
采用“前后”程序将FES-I从英语翻译成波斯语。120名年龄在40至80岁之间（男性占55%）的中风患者完成了波斯语FES-I、老年抑郁量表-15（GDS-15）、一般健康问卷-28（GHQ-28）、伯格平衡量表（BBS）和计时起立行走（TUG）问卷。波斯语量表重测的间隔时间为7至14天。
波斯语FES-I的重测信度和评分者间信度极佳（ICC2,1 = 0.98，p < 0.001），内部一致性较高（克朗巴哈系数 = 0.78）。对波斯语量表中16个条目的因子分析仅显示一个显著因子。波斯语FES-I总分与BBS呈显著负相关（p < 0.001），但与TUG、GHQ-28和GDS-15呈显著正相关。跌倒者和非跌倒者反应性得分的差异产生了较大的效应量（0.46），表明具有良好的区分效度。
波斯语FES-I被证明是一种在实践和研究环境中评估中风患者跌倒恐惧的有效且有价值的测量工具。
