Impairments in executive functioning are common following Acquired Brain Injury, though there are few screening tools which present a time efficient and ecologically valid approach to assessing the consequences of executive impairments. We present the Oxford Digital Multiple Errands Test (OxMET), a novel and simplified computer-tablet version of a Multiple Errands Test. We recruited 124 neurologically healthy controls and 105 stroke survivors to complete the OxMET task. Normative data and internal consistency were established from the healthy control data. Convergent and divergent validation was assessed in a mixed subset of 158 participants who completed the OxMET and OCS-Plus. Test-retest reliability was examined across a mixed subset of 39 participants. Finally, we investigated the known-group discriminability of the OxMET. The OxMET demonstrated very high internal consistency, and stable group level test-retest performance as well as good convergent and divergent validity. The OxMET demonstrated high sensitivity and good specificity in overall differentiation of stroke survivors from controls. The Oxford Digital Multiple Errands Test is a brief, easy to administer tool, designed to quickly screen for potential consequences of executive impairments in a virtual environment shopping task on a computer tablet. Initial normative data and validation within a chronic stroke cohort is presented.
执行功能障碍在获得性脑损伤后很常见，但很少有筛查工具能够有效地评估执行功能障碍的后果，并且具有生态有效性。我们提出了牛津数字多项任务测试（OxMET），这是一种新颖而简化的计算机平板电脑版多项任务测试。我们招募了 124 名神经健康对照者和 105 名中风幸存者来完成 OxMET 任务。从健康对照组的数据中建立了规范数据和内部一致性。在混合的 158 名参与者中评估了收敛和发散验证，他们完成了 OxMET 和 OCS-Plus。在混合的 39 名参与者中检查了测试 - 重测的可靠性。最后，我们研究了 OxMET 的已知组区分能力。OxMET 表现出非常高的内部一致性，以及稳定的组水平测试 - 重测表现以及良好的收敛和发散有效性。OxMET 在总体上将中风幸存者与对照组区分开来，具有较高的敏感性和特异性。牛津数字多项任务测试是一种简短，易于管理的工具，旨在在计算机平板电脑上的虚拟环境购物任务中快速筛查潜在的执行功能障碍后果。目前提出了初步的规范数据和慢性中风队列内的验证。
