Abstract

Background: If an institute is looking for improvement of its learning environment, a reliable and valid assessment tool is needed for measurement of the educational environment .The Dundee Ready Educational Environment Measure (DREEM) has been used in various studies to evaluate the educational environment. However, psychometric evaluations of the instrument seem necessary, for all known versions of the instrument. The aim of this study was to investigate the reliability and validity of Persian version of the DREEM in the major clinical wards in teaching hospitals affiliated to Iran University of Medical Sciences. Methods: This descriptive - analytical study, involved medical students (clinical stagers and interns) in 4 major clinical wards. In this study, DREEM questionnaire was reviewed in content, face validity and construct validity through confirmatory factor analysis. The reliability was calculated according to test - retest and the internal consistency was measured using Cronbach's alpha coefficient. Results: A total number of 267 questionnaires were completed by medical stagers (60%) and interns (40%) including 181 females and 82 males. The mean age of stagers and interns were 23.60 ± 1.27 and 25.45 ± 1.22 years, respectively. The total mean of the questionnaire was calculated as 96.15 (93.5375, 98.7547) out of 176, with 95% confidence interval. The face validity of the questionnaire was confirmed. The mean of content validity ratio (CVR) was calculated as 0.35, and 6 questions were omitted in this step. The content validity index (CVI) was 0.39. The reliability coefficient mean was 0.71. In confirmatory factor analysis five factors were confirmed that changed the orientation of some questions. The Cronbach's alpha coefficient of the whole questionnaire was obtained as 0.914. Conclusion: The modified and validates DREEM questionnaire in Persian language with 44 items and appropriate psychometric attributes is capable of being used in assessment of clinical education environments in Iran.
