Resumo

Introdução: A restrição injustificada de hidratos de carbono nos deportistas pode comprometer o rendimento, a recuperação e a saúde, embora a sua avaliação através de instrumentos válidos e específicos se for limitada.

Objectivo: Desenvolver e validar um instrumento para avaliar a relação disfuncional com os hidratos de carbono em deportistas do Chile e da Argentina.

Metodologia: Foi realizado um estúdio instrumental, transversal e não experimental em 697 deportistas, distribuídos por dois expositores independentes para AFE (n = 288) e AFC (n = 409). O instrumento foi elaborado através de revisão da literatura, avaliação de especialistas e validação aparente. A AFE foi realizada com correlações policóricas, extração por minutos e rotação oblíqua. Posteriormente, foram comparados modelos confirmatórios e avaliada a invariabilidade fatorial entre países.

Resultados: El AFE identificou uma solução de 21 itens e três fatores, com fatorização adequada (KMO = 0,919; p < 0,001) e 42,2% de variação explicada. No AFC, o modelo bifator apresentou um melhor ajuste do que o modelo de três fatores (CFI = 0,951; TLI = 0,939; RMSEA = 0,053; SRMR = 0,044). A fiabilidade foi adequada (α = 0,92; ωt = 0,94; ωh = 0,83), evidenciando uma clara predominância do fator geral. Assim, observou-se invariabilidade fatorial configural, métrica e escalar entre o Chile e a Argentina (ΔCFI ≤ 0,01; ΔRMSEA ≤ 0,015), o que suporta a equivalência do instrumento entre contextos.

Conclusões: O instrumento apresenta validade estrutural, fiabilidade e invariabilidade fatorial adequadas, constituindo uma ferramenta útil para avaliar a relação disfuncional com os hidratos de carbono nos deportistas, facilitando a deteção da temperatura e a intervenção nutricional orientada.
