ABSTRACT

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.

牛津数字多任务测试 (OxMET):验证基于简化的平板电脑多任务测试

摘要

执行功能障碍在获得性脑损伤后很常见,尽管很少有筛选工具能够提供一种时间有效且生态有效的方法来评估执行障碍的后果。我们介绍了牛津数字多任务测试 (OxMET),这是多任务测试的新颖且简化的计算机平板电脑版本。我们招募了 124 名神经健康对照和 105 名中风幸存者来完成 OxMET 任务。从健康对照数据建立规范数据和内部一致性。在完成 OxMET 和 OCS-Plus 的 158 名参与者的混合子集中评估了收敛和发散验证。在 39 名参与者的混合子集中检查了重测信度。最后,我们调查了 OxMET 的已知群体可辨别性。OxMET 表现出非常高的内部一致性、稳定的组级重测性能以及良好的收敛和发散效度。OxMET 在中风幸存者与对照组的总体区分中表现出高灵敏度和良好的特异性。Oxford Digital Multiple Errands Test 是一个简短、易于管理的工具,旨在快速筛查在平板电脑上的虚拟环境购物任务中执行障碍的潜在后果。介绍了慢性中风队列中的初始规范数据和验证。Oxford Digital Multiple Errands Test 是一个简短、易于管理的工具,旨在快速筛查在平板电脑上的虚拟环境购物任务中执行障碍的潜在后果。介绍了慢性中风队列中的初始规范数据和验证。Oxford Digital Multiple Errands Test 是一个简短、易于管理的工具,旨在快速筛查在平板电脑上的虚拟环境购物任务中执行障碍的潜在后果。介绍了慢性中风队列中的初始规范数据和验证。
