Computer-based tests are widely used for the purpose of documenting baseline neurocognitive function, and athletes are often tested in groups. At present, there is limited research on the effects of administering these tests in a group versus individual setting.
Athletes assessed with neurocognitive tests in groups would show decreased performance compared with those assessed individually.
Cohort study; Level of evidence, 3.
High school athletes completed preseason baseline neurocognitive tests either in groups in their school or individually in a private neuropsychological clinic (with no significant between-group differences in sex, history of concussion, and attention deficit disorder/learning disability). All athletes completed the ImPACT (Immediate Post-Concussion Assessment and Cognitive Testing) test battery on 1 occasion, which yielded scores in the area of verbal memory, visual memory, motor processing speed, reaction time, and symptom scores.
Athletes in the group setting scored significantly lower on verbal memory (mean 83.4 vs 86.5; P = .003), visual memory (mean 71.6 vs 76.7; P = .0001), motor processing speed (mean 35.6 vs 38.4; P = .0001), and reaction time (mean 0.61 vs 0.57; P = .001), but not symptom scores (mean 6.1 vs 4.4; P = .11), and exhibited a greater rate of invalid baselines. Similar results were obtained after excluding athletes with attention deficit disorder/learning disability and/or a history of concussion.
Administering baseline neurocognitive testing to athletes in a group setting may introduce extraneous error, negatively affecting test performance.
计算机测试被广泛用于记录神经认知功能的基线，且经常对运动员进行群体测试。目前，关于在群体环境与个体环境下进行这些测试的效果，相关研究有限。
与个体评估相比，在群体环境下接受神经认知测试的运动员表现会下降。
队列研究；证据等级，3 级。
高中运动员在学校的群体环境中或私人神经心理诊所的个体环境中完成 preseason 基线神经认知测试（两组间在性别、脑震荡史和注意缺陷障碍/学习障碍方面无显著差异）。所有运动员均在 1 次就诊时完成了 ImPACT（即刻脑震荡后认知评估和测试）测试套件，其中包含言语记忆、视觉记忆、运动处理速度、反应时间和症状评分。
在群体环境中，运动员的言语记忆（平均 83.4 分比 86.5 分；P =.003）、视觉记忆（平均 71.6 分比 76.7 分；P =.0001）、运动处理速度（平均 35.6 分比 38.4 分；P =.0001）和反应时间（平均 0.61 比 0.57；P =.001）的得分显著更低，但症状评分（平均 6.1 分比 4.4 分；P =.11）无显著差异，且表现出更高的无效基线率。在排除注意缺陷障碍/学习障碍和/或脑震荡史的运动员后，得到了相似的结果。
在群体环境下对运动员进行基线神经认知测试可能会引入额外的错误，从而对测试表现产生负面影响。
