RESUMO -Objetivou-se avaliar a validade de construto e a fidedignidade das escalas de silhuetas de Kakeshita (2008) em adolescentes brasileiros. Após a condução do teste-reteste em 112 participantes com intervalo de um mês, os resultados demonstraram que as escalas foram capazes de discriminar os diferentes grupos de estado nutricional em ambos os sexos; apresentaram coeficientes de correlação entre IMC real, IMC atual e insatisfação e coeficientes de correlação intraclasse elevados, comprovando que o instrumento é apropriado para avaliar a imagem corporal nessa faixa etária.
