Abstract:
The Body Ball Coordination Test for Motor Control is a newly developed
assessment that aims to measure individuals' ability to utilize multiple body parts,
proprioception, balance, vision, and other coordination elements to prevent a ball
from touching the floor. This study focuses on evaluating the test's psychometric
properties, specifically its known-group validity and split-half reliability. Selected
through the purposive sampling method, participants included college-level
students, with 30 experienced student varsity athletes and 23 Service Physical
Education (PE) students. The test’s known-group validity was established by
comparing the performance of these two distinct groups using independent
samples t-test and Cohen’s d effect size (t [51] = -3.188, p= 0.002, d= -0.884),
demonstrating its capacity to differentiate between individuals with varying levels
of motor control skills. The experienced Varsity athletes outperformed the novice
Service PE students on the test, confirming their ability to assess coordination skills
effectively. Furthermore, the split-half reliability analysis using Pearson r
correlation revealed a moderate positive correlation (r = 0.547) between odd and
even sets of test scores, indicating good internal consistency and reliability. Despite
not yielding an exceptionally high correlation coefficient, the test remains a reliable
tool for measuring coordination skills consistently over time. This comprehensive
assessment, which requires precise coordination of various body parts, provides
valuable insights into motor control and brain-body coordination abilities. As
such, the Body Ball Coordination Test can benefit coaches, educators, researchers,
and practitioners in sports, education, and research, assisting in talent
identification, skill development, and studying the relationship between motor
coordination and various factors.
