简明国际跌倒效能感量表在脑梗死患者中的信度和效度检验

Reliability and Validity of Chinese Version of Short Falls Efficacy Scale International in Patients with Cerebral Infarction

目的引入简明国际跌倒效能感量表（简明FES-I）,探讨该量表在脑梗死患者中应用的信度和效度。方法联系欧洲跌倒预防网络工作组（Pro Fa Ne）取得英文版和繁体中文版简明FES-I,进一步修订形成简体中文版。采用便利抽样方法选取2014年12月-2015年5月在天津市2所三级甲等医院住院的脑梗死患者105例,发放简体中文版简明FES-I、修订版跌倒效能感量表（MFES）、广泛性焦虑量表-7（GAD-7）和病人健康状况问卷-9（PHQ-9）进行问卷调查,同期收集患者实验室指标。结果简明FES-I的内在一致性Cronbachα系数为0.98,简明FES-I与MFES呈负相关（r=-0.41,P〈0.001）;与GAD-7（r=0.52,P〈0.001）、PHQ-9（r=0.46,P〈0.001）、C反应蛋白（r=0.21,P=0.032）相关,与其他实验室指标不相关（P〉0.05）。有跌倒史者和无跌倒史者之间简明FES-I评分有显著性差异（P〈0.05）。结论简明FES-I内部一致性高且有效,是一种可应用于筛查国内脑梗死患者跌倒恐惧发生的直接、简便的临床测评工具。

Objective To introduce the Chinese version of short Falls Efficacy Scale International（short FES- I） and test its reliability and validity in patients with cerebral infarction. Methods The English version and the traditional Chinese version of short FES-I were obtained from the Prevention of Falls Network Europe, and the simplified Chinese version was developed after a further revision. A sample of105 inpatients with cerebral infarction from December 2014 to May 2015 were recruited from 2 tertiary hospitals in Tianjin. They were investigated with the simplified Chinese version of short FES- I, modified Falls Efficacy Scale（MFES）, Generalized Anxiety Disorder- 7（GAD-7） and Patient Health Questionnaire-9（PHQ-9）. At the same time, the laboratory indexes of the patients were collected. Results The Cronbach＇s α coefficient of short FES-I was 0.98 and the score of short FES-I was negatively correlated with MFES（r=-0.41, P〈0.001）.Short FES-I was correlated wtih GAD-7 score（r=0.52, P〈0.001）, PHQ-9 score（r=0.46, P〈0.001） and the level of C reaction protein（r=0.21, P=0.032）, but uncorrelated with other laboratory indexes（P〉0.05）. There was significant difference in the score of short FES- I between the patients with or without falling. Conclusion Short FES-I is valid and internal consistant, and can be used as an assessment tool to screen fear of falling among patients with cerebral infarction.
