Abstract
The work aimed to revise the Physical Education Grit Scale (PE-Grit) applicable to Chinese athletes. Five hundred and thirty-eight professional athletes from Chinese sports colleges and provincial sports teams were selected by cluster random sampling. Then, the PE-Grit was analyzed for project analysis, exploratory factor analysis, confirmatory factor analysis, criterion-related validity analysis, and reliability analysis. Independent sample t-test and item-total correlation analysis of the questions showed that 16 items of the scale had good discrimination. According to the confirmatory factor analysis model, the factor structure consisted of 2 subscales and 4 dimensions (χ2/df = 1.827; CFI = 0.961; TLI = 0.953; IFI = 0.961; RMSEA = 0.051). Moreover, Cronbach's α of the total scale and the 4 dimensions were between 0.751 and 0.865. A significant positive correlation existed between the PE-Grit, and self-control, which showed good criterion-related validity. Revised PE-Grit can measure Chinese athletes' physical education grit for its good reliability and validity.
