Design and psychometrics evaluation of Adolescent Physical Literacy Questionnaire (APLQ).

Purpose Despite the global introduction of physical literacy in recent years, a lack of a comprehensive physical literacy tool is still evident in adolescents. This study was conducted to design and perform psychometric evaluation of self-assessment adolescent physical literacy questionnaire in the Iranian sample. Methods A mixed research method, including 3 phases, was used on 836 adolescents in the age range of 12-18 years old. A questionnaire with 59 items was designed based on the qualitative stage, refined during the validity and reliability stages, and finally, formed a questionnaire with 25 items. Results The exploratory factor analysis showed 3 factors with an explanation of 59.5% of the total variance, and the results of confirmatory factor analysis confirmed the 3-factor model. Results also showed good internal consistency (α = 0.951), retest reliability (0.981-0.837), and concurrent validity of the questionnaire with the PPLI instrument (0.680-0.790). Conclusion The results showed good validity and reliability of the Adolescent Physical Literacy Questionnaire (APLQ) with 3 dimensions. Therefore, it can be a suitable tool to assess adolescent physical literacy. Supplementary Information The online version contains supplementary material available at 10.1007/s11332-021-00818-8.
