背景认知状态测验（CBB）是一种计算机化的认知评估工具，可以在诊所或家中完成。设计/实验本回顾性研究调查CBB的练习效果/表现轨迹是否因给药位置而不同。参与者/设置参与者包括1439名基线时年龄50-75岁的认知未受损个体，参与了马约诊所衰老研究（MCSA），一项基于人群的认知老化研究。63%的参与者仅在诊所完成CBB，37%的参与者在诊所和家中完成CBB。线性混合效应模型被用来评估性能轨迹在诊所和在home.ResultsResults会议1至2之间的显着的实践效果，大多数CBB措施。在随后的测试阶段，练习效果继续存在，但程度较低。每个位置的平均练习效果/轨迹相似（家庭与诊所）。一卡学习和一回准确性性能在家里比在诊所，这种差异是很大的幅度为一卡学习的准确性。参与者在家里检测反应时间更快，虽然这种差异是小的幅度。ConclusionsResults表明CBB完成的位置对性能有重要影响，特别是对于一张卡学习的准确性，并有跨重复的会议是类似的实践效果，无论在哪里测试完成。
BackgroundThe Cogstate Brief Battery (CBB) is a computerized cognitive assessment that can be completed in clinic or at home.Design/ObjectiveThis retrospective study investigated whether practice effects / performance trajectories of the CBB differ by location of administration.Participants/SettingParticipants included 1439 cognitively unimpaired individuals age 50-75 at baseline participating in the Mayo Clinic Study of Aging (MCSA), a population-based study of cognitive aging. Sixty three percent of participants completed the CBB in clinic only and 37% completed CBB both in clinic and at home.MeasurementsThe CBB consists of four subtests: Detection, Identification, One Card Learning, and One Back. Linear mixed effects models were used to evaluate performance trajectories in clinic and at home.ResultsResults demonstrated significant practice effects between sessions 1 to 2 for most CBB measures. Practice effects continued over subsequent testing sessions, to a lesser degree. Average practice effects/trajectories were similar for each location (home vs. clinic). One Card Learning and One Back accuracy performances were lower at home than in clinic, and this difference was large in magnitude for One Card Learning accuracy. Participants performed faster at home on Detection reaction time, although this difference was small in magnitude.ConclusionsResults suggest the location where the CBB is completed has an important impact on performance, particularly for One Card Learning accuracy, and there are practice effects across repeated sessions that are similar regardless of where testing is completed.
