OBJECTIVE
The Multiple Errands Test (MET) was designed to measure the effect of executive dysfunction on everyday life activities, but little is known about the cognitive requirements for successful performance. This study's objective was to investigate cognitive functions associated with successful MET performance, specifically, the Baycrest-MET.
METHOD
Correlation analysis examined relationships between Baycrest-MET performance and neuropsychological functioning in participants with acquired brain injury (ABI; N = 27).
RESULTS
The association of tasks omitted with executive function (EF) accounted for 15.2%-42.3% of the variance; the association of tasks omitted with attention and processing speed, for 16.8%-24.0%; and the association of tasks omitted and total rule breaks with visuospatial memory, for 18.5%-31.4%.
CONCLUSION
Poor performance on the Baycrest-MET in people with ABI is associated with impairments of EF, attention, memory, and processing speed. Different patterns of performance may arise from different constellations of impairments.
目的
多任务测试（MET）旨在测量执行功能障碍对日常生活活动的影响，但对于成功完成该测试所需的认知要求知之甚少。本研究的目的是调查与成功完成MET（特别是贝克里斯特 - MET）相关的认知功能。
方法
采用相关性分析研究了获得性脑损伤（ABI；N = 27）参与者的贝克里斯特 - MET表现与神经心理功能之间的关系。
结果
遗漏任务与执行功能（EF）的关联解释了15.2%-42.3%的变异；遗漏任务与注意力和处理速度的关联解释了16.8%-24.0%；遗漏任务和总违规次数与视觉空间记忆的关联解释了18.5%-31.4%。
结论
ABI患者在贝克里斯特 - MET上的表现不佳与EF、注意力、记忆和处理速度受损有关。不同的损伤组合可能导致不同的表现模式。
