Abstract

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.
