This study aimed to translate the Pictorial Scale of Physical Self-Concept for Brazilian Children (PSPPS-BR) into the Brazilian-Portuguese language, conduct a transcultural adaptation of it, and investigate its validity. Method: The authors adopted the reverse translation procedures to obtain the PSPPS-BR's Brazilian-Portuguese version. Three motor behavior experts assessed the scale items' clarity and pertinence. Ten professionals participated in the face validity study. Children (N = 300; 150 girls and 150 boys; 8-10 years old; M[subscript age] = 9.0, SD = 0.81) were randomly selected from six schools in Brazil and assessed using the PSPPS-BR, the Pictorial Scale of Perceived Movement Skill Competence, and the Self-Perception Profile for Children. The children (N = 100) were reassessed for test-retest reliability. Results: High clarity and pertinence agreement among experts (content validity coefficient from 98.4% to 100%; Gwet's agreement coefficient from 0.85 to 1.00, p < 0.001) and among professionals (content validity coefficient clarity: 83-100%, relevance: 90-100%) were obtained. The confirmatory factorial analysis showed adequate model fits (root mean square error of approximation = 0.067; comparative fit index = 0.968; Tukey-Lewis index = 0.949). Polychoric correlations showed an adequate internal consistency for total scale ([alpha] = 0.78) and items (alpha from 0.73 to 0.78). The intraclass coefficient correlation shown strong test-retest reliability (intraclass correlation coefficient > 0.95). Conclusion: The PSPPS-BR showed adequate validity and reliability for Brazilian children.
