肿瘤患者跌倒风险感知量表的编制及信效度检验

Development of Fall Risk Perception Scale for Cancer Patient:reliability and validity testing

目的编制肿瘤患者跌倒风险感知量表并检验信效度,为肿瘤患者跌倒防范提供自评工具。方法通过文献回顾、专家函询、小组讨论等方式构建量表,选取407例肿瘤患者进行调查,检验量表信效度。结果肿瘤患者跌倒风险感知量表包括跌倒认知易感知性(5个条目)、生理状况易感知性(12个条目)、个人活动易感知性(5个条目)、环境因素易感知性(5个条目)、跌倒严重性感知(3个条目)5个维度共30个条目。探索性因子分析提取5个公因子,累计方差贡献率66.746%。量表总的Cronbach′sα系数为0.926,折半信度为0.672,各维度Cronbach′sα系数为0.914~0.970,折半信度为0.877~0.963。量表水平的内容效度指数为0.867,条目水平的内容效度指数为0.813~1.000。验证性因子分析结果显示,χ^(2)/df=1.845,RMSEA=0.059,GFI=0.840,CFI=0.971,NFI=0.939,AGFI=0.811,模型适配良好;AVE平方根均显著大于相关系数,各维度之间有显著相关性(均P<0.05)。结论肿瘤患者跌倒风险感知量表信效度良好,可用于肿瘤患者跌倒风险感知的评估。

Objective To develop the Fall Risk Perception Scale for Cancer Patient and test its reliability and validity,so as to provide a valid self-assessment tool for fall prevention.Methods The scale was constructed through literature review,expert consultations and group discussion.A total of 407 inpatients with cancer were surveyed to examine the reliability and validity of the scale.Results The Fall Risk Perception Scale for Cancer Patients consisted of 30 items factored into 5 dimensions:cognitive susceptibility to falls(5 items),physiological susceptibility(12 items),individual activity susceptibility(5 items),environmental susceptibility(5 items),and perceived severity of falls(3 items).The S-CVI/UA was 0.867,and the I-CVI was between 0.813-1.000.Five common factors were extracted from exploratory factor analysis,and the cumulative variance contribution rate was 66.746%.The total Cronbach′sαcoefficient was 0.926,and the split-half reliability coefficient was 0.672.The Cronbach′sαcoefficient of each dimension was between 0.914-0.970,and the split-half reliability coefficient was between 0.877-0.963.The results of confir-matory factor analysis showed thatχ^(2)/df=1.845,RMSEA=0.059,GFI=0.840,CFI=0.971,NFI=0.939,AGFI=0.811,indicating the model fitted well.The AVE square root was significantly greater than the correlation coefficients,and there was a significant correlation among all dimensions(all P<0.05).Conclusion The Fall Risk Perception Scale for Cancer Patient has good reliability and validity,and can be used to assess patient′s perceived risk of fall.
