Introdução: O raciocínio estadístico é crítico para a tomada de decisão baseada na evidência nas ciências do desporto. No entanto, existem instrumentos psicométricos válidos para esta população.
Objectivo: Desenvolver e apresentar evidências de validade de conteúdo, estrutura interna e fiabilidade de um questionário para avaliar o raciocínio estadístico dirigido a estudantes de ciências do desporto.
Métodos: Foi realizado um estudo de validação psicométrica, que integrou um consenso trietápico Delphi (n=13, especialistas) para a geração de itens. A validade do conteúdo foi quantificada através do índice de validade do conteúdo por item (IVC-I), índice de validade do conteúdo global (IVC-G) e Kappa modificado (K*). Uma mostra de (n=99) alunos (21,9± 2,04 anos) completou o instrumento. Foi executada uma análise fatorial exploratória com uma estimativa robusta de mínimos quadrados ponderados diagonalmente. A fiabilidade foi determinada através da alfa de Cronbach e do coeficiente de correlação intraclasse (CCI).
Resultados: A validade do conteúdo foi ótima (IVC-G: 0,93; K*>0,84). A análise fatorial exploratória indicou uma estrutura bifatorial parcimoniosa de 10 reativos, que explicou os 62,4% da variação total. A consistência interna foi aceitável (α = 0,746), e a estabilidade temporal adequada (ICC= 0,820; IC95%:0,672-0,813).
Conclusões: O questionário REI-Sports mostra propriedades psicométricas de validade e fiabilidade sólidas para avaliar o raciocínio estadístico em estudantes das ciências do desporto. São necessários estudos adicionais para confirmar a sua estrutura fatorial e a sua aplicabilidade noutros contextos.
