Sports concussions are recognized as significant injuries among young athletes. Research demonstrates that return-to-play prior to becoming asymptomatic has significant repercussions including sustained cognitive deficits. Many programs have begun to use computerized testing rather than traditional neuropsychological tests to (a) determine baseline performance, (b) track symptoms, and (c) measure symptoms following concussion. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is one such tool. The current study examined ImPACT's convergent and discriminant validity by comparing scores from sports-related concussion athletes (SRC) to those from nonconcussed controls (CTL). SRC included 29 athletes, ages 12-16, referred for neuropsychological assessment following sports-related concussions. CTL included 25 healthy athletes, ages 12-16, who were concussion-free in the past year. Overall, results showed general support for ImPACT, when used to screen cognition. In fact, all ImPACT domains successfully differentiated between SRC and CTL athletes. Evidence supporting appropriate convergent validity was best for the Visual Memory domain. Further, ImPACT domains demonstrated variable discriminant validity. Overall examination of validity demonstrated that ImPACT has some weaknesses but may have utility in detecting postconcussion cognitive impairment.
运动性脑震荡被认为是年轻运动员中的重大损伤。研究表明，在症状未消失之前就恢复运动有重大影响，包括持续的认知缺陷。许多项目已开始使用计算机化测试而非传统的神经心理学测试来（a）确定基线表现，（b）跟踪症状，以及（c）测量脑震荡后的症状。即时脑震荡后评估和认知测试（ImPACT）就是这样一种工具。本研究通过比较与运动相关脑震荡运动员（SRC）和未受过脑震荡的对照组（CTL）的得分，检验了ImPACT的聚合效度和区分效度。SRC包括29名年龄在12至16岁之间的运动员，他们在与运动相关的脑震荡后被转介进行神经心理学评估。CTL包括25名年龄在12至16岁之间的健康运动员，他们在过去一年中未受过脑震荡。总体而言，结果表明，在用于筛查认知时，对ImPACT有普遍支持。事实上，所有ImPACT领域都成功地区分了SRC和CTL运动员。支持适当聚合效度的证据在视觉记忆领域最为充分。此外，ImPACT领域表现出不同的区分效度。效度的总体检验表明，ImPACT有一些弱点，但在检测脑震荡后认知障碍方面可能有用。
