Pictorial Scale of Physical Self-Concept for Brazilian Children: Validity and Reliability

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; Mage = 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 .85 to 1.00, p < .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 = .067; comparative fit index = .968; Tukey–Lewis index = .949). Polychoric correlations showed an adequate internal consistency for total scale (α = .78) and items (alpha from .73 to .78). The intraclass coefficient correlation shown strong test–retest reliability (intraclass correlation coefficient > .95). Conclusion: The PSPPS-BR showed adequate validity and reliability for Brazilian children.
