This study aimed to translate the Group Environment Questionnaire (GEQ) to the Portuguese language and check its validity by validating the items through confirmatory factor analysis, internal consistency and test-retest reliability of this version. The subjects were seven professionals (four translators and three doctors in Sport Psychology) and 502 athletes of different kinds of collective sports of the state of Paraná. The Portuguese version was obtained from the method of cross-cultural translation. For data analysis it was used confirmatory factor analysis, Cronbach's alpha and the intraclass correlation coefficient. The results showed the Brazilian version contains clear and relevant items, showing Coefficient of Content Validity (CVC) > 0,70; it shows satisfactory internal consistency (r > 0,70) and acceptable test-retest reliability (r > 0,80). The confirmatory factor analysis showed that items 2 ("I'm happy with the amount of playing time I get") and 5 ("Some of my best friends are on this team") don't demonstrated acceptable reliability individually, thus they were excluded; the model with 16 items had satisfactory indices of fit of confirmatory factorial validity. It was concluded that Brazilian version of the GEQ has shown good psychometric characteristics and it proved to be valid to assess the group cohesion in sports teams.
