斯坦福谵妄评估量表的汉化及在胃肠外科术后患者中的信度效度评价

The Chinese version of Stanford Proxy Test for Delirium:reliability and validity study in postoperative patients

目的:汉化斯坦福谵妄评估量表(Stanford Proxy Test for Delirium,S-PTD)并检测其信度、效度,评价其在我国胃肠外科手术患者中的敏感度及特异度。方法:采用Brislin模型对S-PTD进行双人翻译-回译、跨文化调适、预实验,形成中文版S-PTD量表。采取便利抽样法,选取在南京市某三级甲等医院行胃肠外科手术的458例患者进行调查评估。结果:中文版S-PTD量表总内容效度为0.95,各条目内容效度为0.78~1.00。经探索性因子分析,共提取3个公因子,累计方差贡献率为59.368%。量表评估者间信度Kappa值为0.981。量表总的Cronbach’sα系数为0.827,各维度的Cronbach’sα系数为0.726~0.741,Guttman折半信度为0.738,重测信度为0.783;量表阈值为3分,ROC曲线下面积为0.853,灵敏度为0.678,特异度为0.935。结论:中文版S-PTD具有良好的信度、效度,可供我国护士用于术后谵妄患者的筛查。

Objective:To translate the Stanford Proxy Test for Delirium(S-PTD)into Chinese and test its reliability and validity.Methods:The translation process followed the Brislin's model.We recruited 458 patients who were undergoing gastrointestinal surgery in a tertiary grade A hospital in Jiangsu province from October 2021 to September 2022 by convenience sampling method to test the scale's reliability and validity.Results:The content validity of Chinese S-PTD scale was 0.95,and the content validity of each item was 0.78-1.00.By exploring factor analysis,three common factors were extracted,and the cumulative variance contribution rate was 59.368%.The Kappa value of inter-evaluator reliability was 0.981.The Cronbach'sαcoefficient of the scale was 0.827,the Cronbach'sαcoefficient of each dimension was 0.726-0.741,Guttman's half-reliability was 0.738,and the test-retest reliability was 0.783.The scale threshold was 3 points,the area under ROC curve was 0.853,the sensitivity was 0.678,and the specificity was 0.935.Conclusion:The Chinese version of S-PTD scale has good reliability and validity,it can be used for the screening of postoperative delirium patients by Chinese nurses.
