Abstract This study investigated the psychometric properties of the Brazilian version of the Multidimensional Sportspersonship Orientations Scale (MSOS). The cross-cultural adaptation committee was composed of three experts. Our validation sample consisted of 643 athletes from individual and team sports. The results showed clear and relevant content validation and satisfactory internal consistency of the items in the Portuguese version. EFA suggested the exclusion of nine items and the retention of four factors. The CFA analysis with 16 items showed satisfactory adjustment of the model [X²/df = 2.70; CFI = 0.928; TLI = 0.911, RMSEA = 0.05]. The 16-item scale had adequate reliability (> 0.70). It was concluded that the Brazilian version of MSOS showed acceptable psychometric properties.
