Background: Despite many studies on children's physical literacy, less attention has been paid to adolescents' physical literacy. The aim of this study was to design and psychometrics a tool for assessing physical literacy of Iranian adolescents.
Materials and Methods: This study was a mixed study conducted at two stages. At the first stage, the concept of adolescents' physical literacy was identified using a content analysis approach. At the second stage, 12 specialists investigated the content validity and 10 adolescents investigated the face validity of the tool. Then, in a cross-sectional study on 510, 16-18-year-old adolescents who were randomly selected, the validity of the structure was measured by exploratory factor analysis and the reliability of the tool was confirmed through internal consistency and stability of the tool.
Results: A questionnaire with 62 questions was designed based on the qualitative stage, which was refined through validity and reliability stages, and finally a questionnaire with 34 questions was formed. In the exploratory factor analysis, 34 items were loaded in 5 factors. According to the research team, the items of Factor 5 were transferred to Factor 2 due to the conceptual similarity. Finally, the questionnaire included 34 items with 4 factors. Cronbach's alpha coefficient of the tool was 0.93. The retest of the questionnaire at a two-week interval confirmed the stability of the questionnaire (ICC = 0.97).
Conclusion: Based on the results, Adolescents' Physical Literacy Questionnaire with 34 items and 4 dimensions was approved as a valid and reliable tool to measure Iranian adolescents' physical literacy.
