The main objective of this study was to estimate evidence of validity based on internal structure and internal consistency of the Brazilian version of the Mindfulness Scale for Physical Activity (SMS-PA2) in physical activity and sports practitioners. The sample included 231 participants aged between 18 and 72 years. Confirmatory factor analysis showed better fit for the bifactor model (CFI = .990, TLI = .987, RMSEA = .035), with adequate internal consistency indices. Validity evidence was also estimated based on relationships with other variables: positive affect, exercise satisfaction, and negative affect. The study concluded that the Brazilian version of SMS-PA2 is a valid measure, consistent with the original bifactor theoretical structure, supporting its use in assessing mindfulness in the context of physicalactivity, with relevant applications for both research and practice
