老年人跌倒警觉度量表在老年住院病人中的信效度检验

Reliability and validity of the Self-Awareness of Falls in Elderly Scale in elderly inpatients

目的:检验跌倒警觉度量表在老年住院病人中的信效度。方法:采用一般资料量表、跌倒警觉度量表对湖北省某三级甲等医院住院的270例老年病人进行调查。结果:项目分析显示,跌倒警觉度量表的21个条目在高分组和低分组差异均有统计学意义(P<0.01),临界比值为4.682~21.020(P<0.01);4个维度与总分之间的相关系数为0.666~0.856(均P<0.01),21个条目与总分相关系数为0.400~0.781(P<0.01)。条目水平的内容效度指数(I⁃CVI)为0.875~1.000,量表水平的平均内容效度指数(S⁃CVI/Ave)为0.988。探索性因子分析提取4个公因子,分别为身体功能警觉性、安全及环境警觉性、认知行为警觉性、药物警觉性,累积方差贡献率为69.254%。量表总体Cronbach's α系数为0.923,折半信度为0.812。结论:跌倒警觉度量表具有良好的信效度,可作为我国老年住院病人跌倒警觉度评估的可靠工具。

Objective:To examine the reliability and validity of the Self⁃Awareness of Falls in Elderly Scale in hospitalized elderly patients.Methods:270 elderly patients in a tertiary grade A hospital in Hubei province were investigated by general data scale and Self-Awareness of Falls in Elderly Scale.Results:Item analysis showed that there were statistically significant differences between the 21 items of the Self-Awareness of Falls in Elderly Scale in the high score group and the low score group(P<0.01),and the CR value were 4.682-21.020(P<0.01).The correlation coefficients between the four dimensions and the total score were 0.666-0.856(P<0.01),and the correlation coefficients between the 21 items and the total score were 0.400-0.781(P<0.01).Content validity test showed that I-CVI ranged from 0.875 to 1.000,AND S-CVI/Ave was 0.988.Four common factors,which were awareness of physical functions,awareness of activity safety and environment,awareness of cognitive behavioral and awareness of medication,were extracted using exploratory factor analysis,which could explain 69.254% cumulative variance contribution rate.Reliability test showed that the overall Cronbach's α coefficients was 0.923,and the half-fold reliability was 0.812.Conclusion:The Self⁃Awareness of Falls in Elderly Scale has good reliability and validity,and it can be used as a reliable tool for assessment of fall alertness in hospitalized elderly patients in China.
