Methods: Three translations and back translations were conducted by independent evaluators, the semantic equivalence and versions’ evaluation were made, producing a synthesized version. Comments from participants on the preliminary version of the questionnaire were examined. Results: The preliminary Brazilian version of the questionnaire was developed.
