Ecological validity of a simplified version of the multiple errands shopping test

摘要: Shallice and Burgess (1991) reported the utility of Multiple Errands Test (MET) in discriminating executive deficits three frontal lobe patients with preserved high IQ, who were otherwise unimpaired on tests function. The aim this study was to ascertain value a simplified version MET (MET‐SV) for use range people more routinely encountered clinical practice. Main findings as follows: 1) test discriminated well between neurological controls, group effects remained when difference current general cognitive functions (WAIS‐R FSIQ) taken into account. 2) best predictors performance healthy control (n 5 46) age number times participants asked help (with requests associated poorer performance). 3) In group, two clear patterns failure emerged, either characterized by rule breaking or achieve tasks. These different dysexecutive symptoms everyday life. 4) not only made errors than but also ones. A scoring method that took account markedly increased sensitivity. 5) Many passed traditional function still failed MET‐SV. This pattern strongly observed results demonstrate test, suggest there are common independent sources multitasking population: memory dysfunction, initiation problems. (JINS, 2003, 9, 31‐44.)
