ABSTRACT Objective: describe the process of translation and cross-cultural adaptation of the Mayo High Performance Team Scale into Brazilian Portuguese. Method: descriptive study of validation and cross-cultural adaptation of the scale, carried out virtually, following assumptions proposed by Beaton and collaborators. It had a sample of 40 experts, and carried out two rounds, one for validation and one for final assessment. Results: after following all translation steps, the scale was presented to the committee of experts who reached a consensus (IVC between 0.9 and 1.0) that there was no discrepancy, after evaluating the semantic, idiomatic, experiential and conceptual equivalences between the original scale and the translated version. Conclusion: The Brazilian Portuguese version of the MHPTS was adequately translated and validated, revealing excellent potential for use in clinical simulation contexts for multidisciplinary scenarios.
