摘要

摘要目的:鉴于绩效效度测试(pvt)知识在公众中扩散的危害,需要不断开发新的pvt。本研究的目的是验证新开发的视觉关联扩展测试(VAT-E)。方法:VAT-E由24对线图组成;它部分基于格林的单词记忆测试(WMT)范式。在研究1中,我们比较了健康对照(n = 226)、轻度认知障碍(MCI)患者(n = 76)、阿尔茨海默病(AD)患者(n = 26)和被指示假装记忆缺陷的人(n = 29)的vas - e总分。在研究2中,我们比较了按Slick标准分类为神经认知功能障碍(MND) (n = 26)和非MND (n = 67)的诉讼患者。此外,我们将VAT-E与记忆装病测试(Test of Memory Malingering, TOMM)(研究1)和WMT(研究2)进行了比较。结果:结果表明,VAT-E可以将MCI患者(特异性93-100%)或AD患者(特异性92-100%)与被指示假装的患者(敏感性86-100%)区分开来。VAT-E也能区分MND和非MND(敏感性54%,特异性97%)。VAT-E与TOMM对健康对照者和被试者的分类完全一致,与WMT对非MND和MND的分类中等一致。结论:初步证据表明,VAT-E可能是一种有用的PVT,它能够区分真正的记忆障碍,被指示假装记忆障碍的人,以及被怀疑是装病的认知缺陷的人。

The Visual Association Test-Extended: a cross-sectional study of the performance validity measures
Abstract Objective: Given the hazards of knowledge about performance validity tests (PVTs) being proliferated among the general public, there is a continuous need to develop new PVTs. The purpose of these studies was to validate the newly developed Visual Association Test-Extended (VAT-E). Method: The VAT-E consists of 24 pairs of line drawings; it is partly based on Green’s Word Memory Test (WMT) paradigm. In study 1, we compared VAT-E total scores of healthy controls (n = 226), patients with mild cognitive impairment (MCI) (n = 76), patients with Alzheimer’s disease (AD) (n = 26), and persons instructed to feign memory deficit (n = 29). In study 2, we compared litigating patients classified by Slick’s criteria as Malingering of Neurocognitive Dysfunction (MND) (n = 26) or non-MND (n = 67). In addition, we compared the VAT-E to the Test of Memory Malingering (TOMM) (study 1) and the WMT (study 2). Results: Results showed that the VAT-E differentiated patients with MCI (specificity 93–100%) or patients with AD (specificity 92–100%) from persons instructed to feign (sensitivity 86–100%). The VAT-E also differentiated MND from non-MND (sensitivity 54%, specificity 97%). The VAT-E was in perfect agreement with the TOMM in classifying healthy controls and persons instructed to feign, and it was in moderate agreement with the WMT in classifying non-MND and MND. Conclusion: Preliminary evidence shows that the VAT-E may be a useful PVT based on the ability to differentiate between those with genuine memory impairment, persons instructed to feign memory impairment, and a group suspected of malingering cognitive deficits.
