Abstract

Abstract: 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's α, 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.

Key words: Dundee Ready Educational Environment Measure, Reliability, Validity
