The aim of the present study was to assess the validity and reliability of the Falls Efficacy Scale (FES) in Parkinson's disease (PD) patients in Serbia.
A cross-sectional study was carried out at the Clinic for Neurology, between June 2011 and June 2012. A total of 201 consecutive PD outpatients were recruited. The inclusion criteria were: ability to walk independently for at least 10 m, ability to stand for at least 90 s and a Mini-Mental State Examination score >24. The exclusion criteria were: the presence of other major neurological, psychiatric, visual, audio-vestibular and orthopedic disturbances. The 10-item FES was translated according to internationally-accepted methodology. The internal reliability of the Serbian version of the FES was evaluated using Cronbach's alpha coefficient. Reproducibility of the FES was evaluated using the Spearman-Brown coefficient. To evaluate construct validity, an exploratory factor analysis (principal component analysis, varimax rotation) was carried out.
The internal consistency of the Serbian version of the FES was 0.98. Age, duration of disease, Hoehn and Yahr stage, Unified Parkinson's Disease Rating Scale motor score, history of falls, and the Hamilton depression and anxiety scores were significantly correlated with the total FES score. On factor analysis, all 10 items were compact in a one-factor cluster, with an explained variance of 85%. Spearman-Brown's correlation coefficient between the total scores was 0.99.
The psychometric characteristics of the Serbian version of the FES have excellent reliability and validity as an instrument for measuring the fear of falling in PD patients.
本研究旨在评估 Falls Efficacy Scale（FES）在塞尔维亚帕金森病（PD）患者中的有效性和可靠性。
这是一项在神经病学诊所进行的横断面研究，时间为 2011 年 6 月至 2012 年 6 月。共招募了 201 例连续 PD 门诊患者。纳入标准为：能够独立行走至少 10 米，能够站立至少 90 秒，且 Mini-Mental State Examination 评分>24。排除标准为：存在其他主要神经、精神、视觉、听觉-前庭和骨科障碍。根据国际公认的方法对 10 项 FES 进行了翻译。使用 Cronbach's alpha 系数评估塞尔维亚语 FES 的内部信度。使用 Spearman-Brown 系数评估 FES 的可重复性。为评估结构效度，进行了探索性因子分析（主成分分析，方差极大旋转）。
塞尔维亚语 FES 的内部一致性为 0.98。年龄、疾病持续时间、Hoehn 和 Yahr 分期、统一帕金森病评定量表运动评分、跌倒史以及汉密尔顿抑郁和焦虑评分与总 FES 评分显著相关。在因子分析中，所有 10 项都集中在一个因子簇中，解释方差为 85%。总分数之间的 Spearman-Brown 相关系数为 0.99。
作为测量 PD 患者跌倒恐惧的工具，塞尔维亚语 FES 具有良好的信度和效度。
