Abstract:

Objective To sinicize Tyndall-Bailey Falls Risk Assessment Tool For ICU （ICU-FRAT） and test its reliability and validity. Methods Based on Brislin model，the original scale was translated，back-translated，checked and translated，cultural adjusted and pretest to form the Chinese version of ICU-FRAT. A total of 200 ICU patients from 3 hospitals in Nanjing from March to May 2022 were investigated by convenience sampling to evaluate the reliability and validity of the scale. Results The Chinese version of ICU-FRAT has a total of 10 items，with item level content validity index of 0.83 to 1.00，overall consistency level content validity index of 0.90，and average level content validity index of 0.98. After exploratory factor analysis，3 common factors were extracted，and the cumulative variance contribution rate was 79.32%. Confirmatory factor analysis suggested that each test quantity of scale model fit was within an acceptable range. The Cronbach’s α coefficient of the total scale was 0.857；the Cronbach’s α coefficient of each item ranged from 0.830 to 0.867；the half reliability was 0.838. Conclusion The Chinese version of the ICU-FRAT has good reliability and validity，and it can be used to assess the risk of falls in ICU patients.

摘要：

目的 对ICU跌倒风险评估工具（Tyndall-Bailey Falls Risk Assessment Tool for ICU，ICU-FRAT）进行汉化，并检验其信效度。 方法 基于Brislin模型对ICU-FRAT进行翻译、回译、检译、文化调试和预调查形成中文版ICU-FRAT。采用方便抽样法，选取2022年3月—5月南京市3所三级甲等医院ICU患者200例进行调查，以评价量表的信效度。 结果 中文版ICU-FRAT共10个条目，条目水平内容效度指数为0.83~1.00，全体一致性水平内容效度指数为0.90，平均水平内容效度指数为0.98。经探索性因子分析后提取3个公因子，累计方差贡献率为79.32%。验证性因子分析提示，量表模型适配度各检验量均在可接受范围内。量表总的Cronbach’s α系数为0.857，各维度的Cronbach’s α系数为0.830~0.867，折半信度系数为0.838。 结论 中文版ICU-FRAT具有较好的信度和效度，可用于ICU患者跌倒风险的评估。
