韦氏成人智力量表(WAIS)和韦氏记忆量表(WMS)是临床护理和神经病学研究中最常用的两种心理测试。这两种工具(WAIS-IV和WMS-IV)的新修订版最近已经出版，并越来越多地被神经心理学界采用。这两个量表的结构和内容都发生了重大变化，如果使用它们的前身开发的算法，可能会导致患者分类不准确。目前在神经学人群中没有足够的临床数据来确保它们在神经心理学评估中的适当应用。我们提供了这些重要的新神经心理学工具的观点，评论了在缺乏适当的证据基础支持其递增有效性的情况下采用这些测试的压力，并描述了对患者护理和持续研究应用的潜在负面影响。
The Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Memory Scale (WMS) are 2 of the most common psychological tests used in clinical care and research in neurology. Newly revised versions of both instruments (WAIS-IV and WMS-IV) have recently been published and are increasingly being adopted by the neuropsychology community. There have been significant changes in the structure and content of both scales, leading to the potential for inaccurate patient classification if algorithms developed using their predecessors are employed. There are presently insufficient clinical data in neurologic populations to insure their appropriate application to neuropsychological evaluations. We provide a perspective on these important new neuropsychological instruments, comment on the pressures to adopt these tests in the absence of an appropriate evidence base supporting their incremental validity, and describe the potential negative impact on both patient care and continuing research applications.
