摘　　要：目的 汉化临床流行病学知识评估量表(U-CEP)并评价中文版U-CEP的信度和效度,旨在为临床流行病学教育和研究提供测量与评估工具。方法 依据Brislin量表翻译模型对U-CEP量表进行翻译和调适,以全国临床医生作为研究对象,采用网络调查方法对研究对象开展中文版U-CEP调查,使用SPSS 26.0软件对中文版U-CEP进行项目分析、信度分析和效度分析。结果 项目分析结果显示,除条目4外其他24个条目的区分度决断值为2.902~14.609(P<0.01);所有条目的 ITC均为正数,5个条目的 ITC<0.15(20%),2个条目ITC≥0.15~0.20(8%),6个条目ITC≥0.20~0.40(24%),12个条目ITC≥0.40(48%)。在信度方面,中文版U-CEP整体Cronbach’s α系数为0.80,逐项删除条目的 Cronbach’s α系数范围为0.752~0.805;量表重测信度为0.848(P<0.001);量表复本信度为0.838(P<0.001)。在效度方面,专家分析结果显示量表内容效度良好;结构效度分析显示量表条目的累积方差贡献率为57.50%;没有调查对象得满分或零分,未发现天花板效应和地板效应;不同学历、有无系统学习过相关知识的临床医生的U-CEP总得分差异有统计学意义(P<0.05)。结论 中文版U-CEP量表有良好的信效度,且有着良好的文化适配性,能够有效评估中国临床医生的临床流行病学知识。Objective The purpose of this study was to translate the U-CEP scale into Chinese,and evaluate the reliability and validity of the Chinese version of the U-CEP,in order to provide a measurement and evaluation tool for clinical epidemiology education and research.Methods The U-CEP scale was translated and adapted using the Brislin translation model.A nationwide survey of clinicians was conducted using the Chinese version of the U-CEP.Item analysis,reliability analysis,and validity analysis were performed using SPSS 26.0 software.Results The discriminant validity analysis showed that except for item 4,the critical value(CR)of the other twenty-four items differed significantly between high and low groups(P<0.01),with CR values ranging from 2.902 to 14.609.The ITCs of the 25 items were all positive,with 5 items having an ITC<0.15(20%),2 items having ITC≥0.15~0.20(8%),6 items having ITC≥0.20~0.40(24%)and 12 items having ITC≥0.40(48%).In terms of reliability,the overall Cronbach'sαcoefficient of the Chinese version of the U-CEP was 0.80,with Cronbach'sαcoefficient ranging from 0.752 to 0.805 when deleting each item one by one.The test-retest reliability was 0.848(P<0.001).The alternative-form reliability was 0.838(P<0.001).In terms of validity,expert analysis showed that the content validity of the Chinese version of the U-CEP was good.The construct validity analysis showed that the cumulative contribution rate of the 25 items was 57.50%.No respondent scored full marks or zero marks,indicating that no ceiling or floor effects were found.There were statistically significant differences in the total scores among clinicians with different educational backgrounds or with or without systematic learning of relevant knowledge(P<0.05).Conclusion The Chinese version of the U-CEP has good reliability and validity,as well as good cultural adaptability.It can effectively assess a physician's knowledge of clinical epidemiology.
