This study analyzed the cross-cultural adaptation of the Sport Motivation Scale-II (SMS-II). To this end, three studies were conducted. The first consisted of translating SMS-II to the Portuguese language and adapt its content to the Brazilian context. In the second, 364 athletes from a range of individual and team sports responded to the adapted version of SMS-II. In study 3, 50 athletes responded to the SMS-II at two moments. Study 1 showed that the Portuguese version contains clear and relevant questions (CVC>0.80). Study 2 revealed that SMS-II has good internal reliability (α>0.70/CR>0.70), except the Introjected Regulation (α>0.61/CR>0.56). Confirmatory Factor Analysis revealed that all items had acceptable factor loadings, except itens 1 and 7 (introjected regulation); the final (modified) SMS-II model had satisfactory fit and the multi-group analysis showed the invariance between men and women. Further, study 3 showed acceptable temporal stability (ICC>0.70). It was concluded that the cross-cultural adaptation of the SMS-II to the Portuguese language showed acceptable psychometric properties, however, its limitations must be explored in future studies.
