Measuring the Concurrent Validity of the Athletic Skills Track Using Expert Judgment

Purpose: The aim of this study is to measure the concurrent validity of the Athletic Skills Track (AST) by examining whether its outcome score correlates with the holistic judgments of experts about the quality of movement. Method: Video recordings of children performing the AST were shown to physical education teachers who independently gave a holistic rating of the movement quality of each child. Results: Both intra- and interrater reliability of the teachers' ratings were moderate to good. The holistic judgments on movement quality were significantly correlated with AST time, showing that higher ratings were associated with less time required to complete the track. Next, hierarchical stepwise regression indicated that in addition to the holistic rating, also age, but not gender, explained part of the variance in AST time. Conclusion: The findings show that the AST has good concurrent validity and provides a fast, indirect indication for quality of movement.

Automated summary

The purpose of this study is to measure the concurrent validity of the Athletic Skills Track (AST) by examining its correlation with the holistic judgments of experts about movement quality. The results show that the holistic ratings of movement quality by teachers are significantly correlated with AST time, indicating that higher ratings are associated with shorter completion time. In addition to holistic ratings, age also explains part of the variance in AST time, while gender does not. This study suggests that the AST has good concurrent validity and can provide a fast, indirect indication of movement quality.
