摘要
目的:评价医学教育环境评估量表(DREEM)在我国口腔医学生中应用的信度和效度。方法:采用DREEM量表中文版在重庆医科大学口腔医学本科生中进行问卷调查,最终对调查结果进行统计学分析,考评量表的信度和效度。其中信度采用内部一致性信度和分半信度进行分析;效度采用探索性因素分析和收敛效度进行分析。采用SPSS22.0软件包对数据进行信度和效度检验。结果:共回收有效问卷260份。量表总的Cronbachα系数为0.936,Guttman分半信度系数为0.816。经过探索性因子分析,提取5个因子,累积贡献率达47.071%,显示量表存在预想的连带关系和逻辑关系。量表的Spearman等级相关系数为0.447~0.556之间。结论:医学教育环境评估量表在我国口腔医学生中应用具有良好的信度和效度,可在我国口腔医学教育环境的评价中进一步推广应用。
PURPOSE:To evaluate the reliability and validity of the Dundee Ready Educational Environment Measure(DREEM)among Chinese dental students.METHODS:Students’perceptions of the educational environment were evaluated using the Chinese version of the 50-item DREEM.When they accomplished the questionnaires,the collected data were analyzed to evaluate the reliability and validity of the scale.Reliability was analyzed by internal consistency and split half reliability,and validity was analyzed by exploratory factor analysis and convergent validity.The data were analyzed by reliability and validity test using SPSS 22.0 software package.RESULTS:A total of 260 dental students were enrolled in this study.All the DREEM questionnaires were completely filled out.The Cronbach’sα,split-half reliability of the scale was 0.936,0.816.By factor analysis of construct validity,the 50 items were classified into 5 domains,the cumulative proportion was 47.071%.The scale had certain logical relation between the items in the same domains.The Spearman’s rank correlation coefficient of the scale was between 0.447 and 0.556.CONCLUSIONS:With satisfactory psychometric properties,DREEM is suitable for assessing educational environments among Chinese dental students.
