Computerized neuropsychological testing has become an important tool in the identification and management of sports-related concussions; however, the psychometric effect of repeat testing has not been studied extensively beyond test-retest statistics. The current study analyzed data from Division I collegiate athletes who completed Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) baseline assessments at four sequential time points that varied over the course of their athletic careers. Administrations were part of a larger National Institutes of Health (NIH) study. Growth curve modeling showed that the two memory composite scores increased significantly with successive administrations: Change in Verbal Memory was best represented with a quadratic model, while a linear model best fit Visual Memory. Visual Motor Speed and Reaction Time composites showed no significant linear or quadratic growth. The results demonstrate the effect of repeated test administrations for memory composite scores, while speed composites were not significantly impacted by repeat testing. Acceptable test-retest reliability was demonstrated for all four composites as well.
计算机化神经心理学测试已成为识别和管理与运动相关脑震荡的重要工具；然而，除了重测统计数据外，重复测试的心理测量效应尚未得到广泛研究。当前研究分析了来自美国大学体育协会（NCAA）一级联盟大学生运动员的数据，这些运动员在其运动生涯的不同阶段的四个连续时间点完成了脑震荡后即刻评估和认知测试（ImPACT）基线评估。这些测试是美国国立卫生研究院（NIH）一项更大规模研究的一部分。生长曲线模型显示，随着测试次数的增加，两个记忆综合得分显著提高：言语记忆的变化最适合用二次模型表示，而视觉记忆最适合用线性模型表示。视觉运动速度和反应时间综合得分未显示出显著的线性或二次增长。结果表明重复测试对记忆综合得分有影响，而速度综合得分未受到重复测试的显著影响。所有四个综合得分的重测信度也都在可接受范围内。
