The two aims of this study are (1) to examine the concurrent and discriminant validity of a newly developed virtual ball catching test and (2) to explore the ball catching performance of typically developing children in a virtual environment.
Three groups of children aged 60- to 140-mo-old (n = 368) participated in this study: (1) typically developing children (n = 272), (2) children with diagnoses of developmental coordination disorders (n = 33), and (3) children with premature birth history (n = 63).
The concurrent validity of the virtual ball catching test was good, with Pearson's correlation coefficient = 0.67 between the virtual ball catching test and the Van Waelvelde's short ball catching test in successful catching rate. The discriminant validity of the virtual ball catching test was acceptable in differentiating the performance among typically developing children, children with developmental coordination disorders, and children with preterm history. The significant main effects in age, sex, speed, and location (Ps < 0.001) as well as significant interaction effects in age x location and age x speed were found when examining the virtual ball catching performance of typically developing children.
The virtual ball catching test demonstrates acceptable psychometric properties in assessing the ball catching performance of children aged 5-11 yrs. We propose that testing children's motor performance in a virtual environment might be a useful and promising alternative for clinical assessment. Future research on its clinical application is needed.
本研究有两个目的:(1)检验新研发的虚拟接球测试的同时效度和判别效度;(2)探索正常发展儿童在虚拟环境中的接球表现。
三组年龄在 60-140 个月(n=368)的儿童参与了本研究:(1)正常发展儿童(n=272);(2)有发展性协调障碍诊断的儿童(n=33);(3)有早产史的儿童(n=63)。
虚拟接球测试的同时效度良好,在成功接球率上,虚拟接球测试与 Van Waelvelde 短球接球测试的 Pearson 相关系数为 0.67。虚拟接球测试在区分正常发展儿童、有发展性协调障碍儿童和有早产史儿童的表现方面具有可接受的判别效度。在检查正常发展儿童的虚拟接球表现时,发现年龄、性别、速度和位置有显著的主效应(P<0.001),以及年龄 x 位置和年龄 x 速度的显著交互效应。
虚拟接球测试在评估 5-11 岁儿童的接球表现方面具有可接受的心理测量特性。我们提出,在虚拟环境中测试儿童的运动表现可能是临床评估的一种有用且有前途的替代方法。未来需要对其临床应用进行研究。
