背景资料：有必要制定一种评估容易和困难的身体活动和社会活动的跌倒恐惧指标，并适用于各种语言和文化背景，以便在不同国家和环境的研究和人群之间进行直接比较。开发一种改进版的福尔斯效能量表以满足这一需要，并建立其心理测量学特性、可靠性，和同时效度（即，它表明了预期的关系与年龄，福尔斯历史和福尔斯危险因素）。设计：横断面调查。设置：社区样本。方法：704人年龄在60和95岁之间完成了福尔斯疗效量表-国际（FES-I），无论是在邮政自我完成格式或结构化面试。结果：FES-I具有良好的内部信度和重测信度（Cronbach’s α =0.96，ICC=0.96）。因素分析表明，一个单一的潜在因素，两个维度评估关注要求不高的体育活动，主要是在家里，和关注更多的要求体育活动，主要是在家庭以外。FES-I在区分性别、年龄、职业、过去一年中的福尔斯跌倒和福尔斯跌倒风险因素方面的差异方面略优于原始FES项目（慢性疾病，服用多种或精神药物，头晕）。结论：FES-I与现有的最佳跌倒恐惧测量方法具有密切的连续性，良好的心理测量特性，并评估与体力和社会方面的基本活动和要求更高的活动有关的问题。需要进一步的研究来确认跨文化和预测效度。
Background: there is a need for a measure of fear of falling that assesses both easy and difficult physical activities and social activities and is suitable for use in a range of languages and cultural contexts, permitting direct comparison between studies and populations in different countries and settings.Objective: to develop a modified version of the Falls Efficacy Scale to satisfy this need, and to establish its psychometric properties, reliability, and concurrent validity (i.e. that it demonstrates the expected relationship with age, falls history and falls risk factors).Design: cross-sectional survey.Setting: community sample.Method: 704 people aged between 60 and 95 years completed The Falls Efficacy Scale-International (FES-I) either in postal self-completion format or by structured interview.Results: the FES-I had excellent internal and test-retest reliability (Cronbach's alpha=0.96, ICC=0.96). Factor analysis suggested a unitary underlying factor, with two dimensions assessing concern about less demanding physical activities mainly in the home, and concern about more demanding physical activities mainly outside the home. The FES-I had slightly better power than the original FES items to discriminate differences in concern about falling between groups differentiated by sex, age, occupation, falls in the past year, and falls risk factors (chronic illness, taking multiple or psychoactive medications, dizziness).Conclusions: the FES-I has close continuity with the best existing measure of fear of falling, excellent psychometric properties, and assesses concerns relating to basic and more demanding activities, both physical and social. Further research is required to confirm cross-cultural and predictive validity.
