目的：在脑震荡管理中，将伤后表现与伤前基线进行重复认知评估是常见的。尽管伤后测试通常在临床环境中进行，但基线测试可能在一对一监督下单独进行、在有监督的小组中进行或无监督进行。这些不同的测试环境对认知表现的影响程度尚未得到很好的理解。为了评估在这些环境下Cogstate简易测试组（CBB）的表现是否存在差异，将在一对一监督下单独完成的测试与在有监督的小组中或单独但无监督情况下进行的测试进行了比较。
方法：采用交叉研究设计，以考虑个体差异或测试顺序的任何影响，从而对测试环境对认知表现的影响进行无偏检验。年轻成年参与者在完成小组或无监督测试之前或之后完成了一项有个体监督的测试。
结果：同一个体在不同测试环境下的CBB分数没有显著差异。在有监督与无监督测试中，效应量的大小范围从0.09到0.12；在CBB各项任务中，个体与小组测试的效应量从0.01到0.37。
结论：这些结果表明，在不同环境下使用CBB进行的认知测试能够提供与在个体监督测试期间获得的数据相当的有效认知数据。
Objective: Repeat cognitive assessment comparing post-injury performance to a pre-injury baseline is common in concussion management. Although post-injury tests are typically administered in clinical settings, baseline tests may be conducted individually with one-on-one supervision, in a group with supervision, or without supervision. The extent to which these different test settings affect cognitive performance is not well understood. To assess if performance on the Cogstate Brief Battery (CBB) differs across these settings, tests completed individually with one-on-one supervision were compared to those taken either in a group with supervision or individually but without supervision. Method: A crossover study design was utilized to account for any effect of individual variability or test order to provide an unbiased examination of the effect of test setting on cognitive performance. Young adult participants completed an individually supervised test either before or after also completing a group or unsupervised test. Results: CBB scores from the same individuals were not significantly different across test settings. Effect sizes ranged in magnitude from .09 to .12 for supervised versus unsupervised tests and from .01 to .37 for individual versus group tests across CBB tasks. Conclusion: These results suggest that cognitive testing with the CBB in alternate settings can provide valid cognitive data comparable to data obtained during individually supervised testing.
