Testing Basic Basketball Skills: Evaluating Validity and Reliability in the Context of Gross Motor Development

Objective: This study aims to measure the validity and reliability of the basketball ability test and the Test of Gross Motor Development (TGMD) as a tool for assessing motor and basketball abilities in early childhood. Methods: Research subjects consisted of 21 young basketball players from clubs and academies in the Jakarta Region, with x̅ age of 5.9 years old (SD ± .831) and x̅ BMI of 16.2 (SD ± 1.23). The basketball ability test includes running, jumping, changing direction, and throwing and catching the ball. TGMD is used to assess locomotor skills and object control. Results: The results of the analysis show that both tests have high validity and reliability in measuring children's basketball and motor skills. Correlations between tests indicate effectiveness in evaluating important aspects of motor skills. A significant relationship between test results and measured motor abilities supports construct validity. High reliability shows the consistency of test results over time. Conclusion: The basketball ability test and TGMD were proven to be valid and reliable for assessing motor skills and basketball in early childhood. Both tests can be used in physical education and motor skill development, providing valuable insight for coaches and educators. Further research is needed to test the applicability of this test to a broader population.
