The objective of the study was to determine the psychometric properties of the Dundee Ready Education Environment Measure (DREEM) questionnaire in students of a Peruvian medical school. Participants were first-to-sixth-year students, invited to participate through a web platform. In the analysis the alpha coefficient of Cronbach was used to evaluate internal consistency. In addition, a confirmatory factorial analysis was performed to evaluate the construct validity of the subscales of the DREEM. The adjustment quality indexes used were: Root Mean Square Error Approximation (RMSEA), the Index of Benchmarking (CFI), Tucker-Lewis Index (TLI), and the Standardized Root Mean Residual (SRMR). The results showed that the social self-perception dimension had an alpha of Cronbach of less than 0.70. In addition, the quality indices did not support the five-dimensional structure of the DREEM. In conclusion, the DREEM questionnaire did not perform optimally in this Peruvian sample.
