Questionário do perfil de alfabetização física (qpaf): análise da validade estrutural e consistência interna do instrumento para avaliação de crianças e jovens com deficiências

Abstract

Introduction: This study aims to analyze the measurement properties of the Physical Literacy Profile Questionnaire (PLPQ), developed to assess the level of physical literacy in children, adolescents, and young adults with disabilities, encompassing the skills, behaviors, and values needed for active participation in different contexts. The study is based on the need to confirm that the items of the PLPQ are appropriate for measuring the construct of physical literacy consistently and accurately. Methodology: The sample consisted of 110 caregivers of children with disabilities with an average age of 10.08 ± 3.96 years. The internal consistency of the instrument was evaluated using Cronbach's alpha. Structural validity was tested through confirmatory factor analysis, assessing unidimensionality, local independence, and item monotonicity, using Item Response Theory models to estimate item parameters, including characteristic curves and information curves. Results: The analysis revealed that two items from the initial version of the instrument did not exhibit the expected behavior. Specifically, item 1 showed a discrimination level of 0.069, well below the reference value of 0.7. Additionally, item 9 had a positioning on the scale of -4.93, also below the critical value of -3.0. As a result, these items were removed, leading to the final version of the PLPQ with 22 items, which displayed good discrimination and positioning indices and satisfactory overall internal consistency, with a Cronbach’s alpha=0.93. Conclusion: The results indicate that the final version of the PLPQ has adequate measurement properties for assessing physical literacy in children, adolescents, and young adults with disabilities. The internal consistency and structural validity of the instrument were confirmed, suggesting that the PLPQ can be a useful tool for assessing this construct in populations with similar characteristics.
