The interest of the scientific community in the tactical skills of practitioners of collective invasion sports has generated the need for the development of instruments capable of measuring such skills in an attempt to contribute in this direction. The present study aimed to translate and analyse the psychometric properties (confirmatory validity and reliability) of the Tactical Skills Inventory for Sports into the Portuguese language in young Brazilian basketball players. A total of 866 basketball players with a mean age of 15.83± 1.25 years participated in the study. The Brazilian version of Tactical Skills Inventory for Sports was produced. Cronbach’s alpha was calculated, and the Confirmatory Factor Analysis was performed. The Cronbach’s alpha presented high indexes for 3 dimensions of Tactical Skills Inventory for Sports, and the sum of the items the Cronbach’s alpha value was 0.91. The results of the Confirmatory Factor Analysis presented values= 3.120; Confirmatory Fit Index= 0.925; Tucker-Lewis index= 0.914; Standardized Root Mean Square Residual= 0.039; Root Mean Square Error of Aproximation= 0.050 (90% CI= 0.045–0.054). The obtained results allow us to consider the adapted Brazilian version of Tactical Skills Inventory for Sports, with 22 items, a robust and valid questionnaire, for use in young Brazilian basketball players.
