主要目的：本研究检验了用于评估运动相关脑震荡的计算机化神经心理测试组合Impact的结构和同时效度。研究设计：大约100名神经功能正常的本科生完成了Impact，国家橄榄球联盟(NFL)使用了一系列传统的神经心理测试。方法和程序：参与者按平衡顺序完成两个测试。因子分析考察了冲击的成分结构和NFL电池的因子结构。相关分析评估了两个电池内和两个电池之间的变量之间的关系。主要结果：使用NFL电池发现了一个四因素解决方案，可以解释70%的变异，包括一般记忆、心理加工速度、言语记忆和加工速度以及听觉和言语工作记忆。用Impact电池找到了一个解释69%差异的五因素解决方案，其中包括评估强迫选择效率的组件、言语和视觉记忆、抑制认知能力、使用记忆组件的视觉处理能力和来自Colour Match Total Commission的单一加载的因素。相关性揭示了两个电池之间的一系列显著和不显著的相关性。结论：尽管两个电池在其评估的结构(如记忆、抑制认知能力)上存在重叠，但它们的因子结构也存在显著差异。
Primary objective: This study examined the construct and concurrent validity of ImPACT, a computerized neuropsychological test battery used for evaluating sports-related concussion.Research design: Approximately 100 neurologically intact undergraduates completed ImPACT and a battery of traditional neuropsychological tests utilized by the National Football League (NFL).Methods and procedures: Participants completed the two batteries in a counterbalanced order. Factor analyses examined the component structure of ImPACT and the NFL battery's factor structure. Correlational analyses assessed relationships among variables within and across the two batteries.Main results: A four-factor solution explaining 70% of variance was found with the NFL battery, including general memory, mental processing speed, verbal memory and processing speed and auditory and verbal working memory. A five-factor solution explaining 69% of variance was found with the ImPACT battery, with components assessing forced choice efficiency, verbal and visual memory, inhibitory cognitive abilities, visual processing abilities with a memory component and a factor with a single loading from Colour Match Total Commissions. Correlations revealed a range of significant and nonsignificant correlations between the two batteries.Conclusions: While both batteries overlap regarding their assessed constructs (e.g. memory, inhibitory cognitive abilities) notable differences in their factor structures were present as well.
