Reliability and Validity of the Physical Literacy Questionnaire for Chinese Children Aged 4-6 Years

The study was to validate the reliability and validity of the Physical Literacy Questionnaire (PL-C Quest) for Chinese children aged 4-6 years. Data were collected from 1677 kindergarten children (864 boys and 813 girls) aged 4-6 years in five cities cross different regions in China. The item analysis was conducted to assess item discrimination. Reliability was assessed through both internal consistency (Cronbach’s alpha) and test-retest reliability (ICC). Construct validity was examined using Exploratory Factor Analysis (EFA) and subsequently confirmed with Confirmatory Factor Analysis (CFA). The results revealed that (1) in the item analysis, the t-values of the 30 items ranged from 11.553 to 27.685 (p < 0.05); (2) in the reliability test, the Cronbach’s alpha of the PL-C Quest total assessment was 0.896, and the retest reliability was 0.866, indicating that the questionnaire has high internal consistency and measurement stability; (3) in the validity analysis, EFA validated the four-factor structure of the PL-C Quest, and the results of the CFA indicated a good model fit (χ2/df = 2.985, RMSEA = 0.049, GFI = 0.896). The PL-C Quest has shown good reliability and validity in the assessment of Physical Literacy (PL) for children aged 4-6 years in China.
