医院科研竞争力评价体系的信度和效度分析

Analysis of the reliability and validity about scientific research competence indicators system of hospitals in Shanghai

目的 对已经建立的医院科研竞争力评价体系进行信度和效度分析.方法 利用评价体系对上海市34家三甲医院及其业务科室的科研竞争力进行评价.采用Cronbach＇s alpha系数对指标体系的信度进行评价,采用基于结构方程模型的验证性因子分析评价体系的结构效度.结果 经结构调整后,比较拟合指数CFI为1.000,麦氏拟合指数MFI为1.009,近似平方根误差RMSEA为0.000,增量拟合指数IFI为1.028,提示模型拟合度好,当前的变量间结构关系较好.整体的Cronbach＇s alpha系数为0.768.结论 该评价体系有较好的信度和结构效度.

Objective To analyze the reliability and validity of an established ＂Research Hospital Competitiveness Evaluation System＂.Methods To evaluate the research competitiveness of 34 tertiary hospitals and their departments in Shanghai using above system.The reliability and validity of the indicator system were analyzed with the Cronbach＇s alpha coefficient, and confirmatory factor analysis based on the structural equation model.Results After adjusting for structure of the index system via item parceling, the CFI, MFI, RMSEA AND IFI were 1.000, 1.009, 0.000 and 1.028, the Cronbach＇s alpha of whole set indicators system was 0.768.Conclusions The results suggested that the measured reliability and validity are both in good degree, survey results can reflect the actual competence of evaluated hospitals.
