0152/2019 - Validity and reliability of an instrument to measure factors associated with screen time in Brazilian students. Validade e confiabilidade de um instrumento para avaliar fatores associados ao tempo de tela em escolares Brasileiros.
Este estudo analisou a validade e a confiabilidade de um instrumento com escalas de fatores associados ao tempo de tela em adolescentes. Dois estudos transversais incluíram escolares para análises de validade (n=1138, 51,5% meninos) e reprodutibilidade teste-reteste (n=194, 56,2% meninos) do instrumento. Fatores individuais (atitude, autoeficácia e expectativas), do ambiente social (comportamentos, regras, crenças e suporte familiar e suporte dos membros da escola) e físico (casa e no quarto) associados ao tempo de tela foram avaliados. Todas as escalas do instrumento atenderam os critérios estatísticos de validade da análise fatorial exploratória (p

Abstract:
This study analyzed the validity and reliability of an instrument with scales measuring factors associated with screen time in adolescents. Two cross-sectional studies included students for analyses of validity and internal consistency (n=1138, 51.5% boys) and test-retest reproducibility (n=194, 56.2% boys). Individual (attitude, self-efficacy and expectations), social (behaviors, rules, beliefs and family support and support of school members) and physical environmental (home and bedroom equipment) factors of screen time were evaluated. All the scales of the instrument met the statistical criteria of the validity of the exploratory factorial analysis (p
