简版老年综合评估问卷的汉化及在癌症患者中的信效度研究

Chinese version of the abbreviated Comprehensive Geriatric Assessment and its reliability and validity in cancer patients

目的汉化简版老年综合评估问卷,并对其进行信效度检验。方法根据量表跨文化研究指南对英文版简版老年综合评估问卷进行正译、回译和跨文化调适,最终形成中文版简版老年综合评估问卷。采用便利抽样法,选取2021年2—7月南通大学附属医院3个科室的275例老年癌症患者为研究对象,采用一般资料调查表、中文版简版老年综合评估问卷和衰弱身体表型量表对患者进行调查。运用SPSS 25.0和AMOS 24.0软件检验问卷的信效度。结果中文版简版老年综合评估问卷共3个维度15个条目,问卷的Cronbach’’sα系数为0.806,抑郁、功能、认知维度的Cronbach’’sα系数分别为0.919,0.957,0.806,评分者间一致性的Kappa值为0.778。条目水平的内容效度指数为0.833~1.000,问卷水平的内容效度指数为0.943。探索性因子分析共析出3个公因子,累计方差贡献率为81.181%。该问卷测评结果与衰弱身体表型量表呈强相关(r=0.629,P<0.01)。结论中文版简版老年综合评估问卷信效度良好且筛查性能较佳,适用于对老年癌症患者衰弱的初步筛查。

Objective To translate the abbreviated Comprehensive Geriatric Assessment(aCGA)into Chinese and test its reliability and validity.Methods According to the guideline of instruments or scales for use in cross-cultural health care research,the English version of aCGA was translated correctly,back translated,and cross-cultural adapted,ultimately forming the Chinese version of aCGA.From February to July 2021,275 elderly cancer patients from three departments of Affiliated Hospital of Nantong University were selected as the study subject by convenience sampling.Patients were surveyed using the General Information Questionnaire,Chinese version of aCGA,and the Fried Frailty Phenotype.SPSS 25.0 and AMOS 24.0 software were used to test the reliability and validity of the questionnaire.Results The Chinese version of aCGA consisted of three dimensions and 15 items.The Cronbach'sαcoefficient of the questionnaire was 0.806,and the coefficients of depression,function,and cognition dimensions were 0.919,0.957,and 0.806,respectively.The Kappa value for consistency between raters was 0.778.The content validity index at the item level was 0.833 to 1.000,and the content validity index at the questionnaire level was 0.943.Exploratory factor analysis identified three common factors,with a cumulative variance contribution rate of 81.181%.The evaluation results of the questionnaire was strongly correlated with the Fried Frailty Phenotype,and the difference was statistically significant(r=0.629,P<0.01).Conclusions The Chinese version of aCGA has good reliability,validity,and screening performance,making it suitable for preliminary screening of frailty in elderly cancer patients.
