Method: A total of 117 university students of both sexes were evaluated. The validated questionnaire was the body figure scale. Data were compared using a t-test for paired samples, concordance between versions was tested by the kappa index, and reliability by the intraclass correlation coefficient and the percentage of agreement, using the Statistical Package for the Social Sciences 15.0 software. Results: The percent agreement and intraclass correlation coefficient values ranged from low to high according to version, sex and the item analyzed. The kappa index was higher than 0.60, indicating good correlation. Conclusions: The version of the questionnaire does not modify the assessment of body image.
