为了评估神经损伤对认知表现的影响，通常有必要在损伤发作之前获得患者的一般认知能力的基线（或“病前”）估计。在本文中，我们考虑了一系列常见的方法来产生这种估计，包括基于当前最佳性能，嵌入式“持有/不持有”测试，人口统计信息，和文字阅读能力。92名神经系统健康的成年参与者在完整的韦氏成人智力量表-第四版（WAIS-IV; Wechsler，D.（2008年）。韦氏成人智力量表（第四版）。圣安东尼奥，德克萨斯州：皮尔逊评估。）和两个广泛使用的文字阅读测试：国家成人阅读测试（NART;纳尔逊，H。E.（1982年）。国家成人阅读测试（NART）：用于评估痴呆患者的病前智力：测试手册。温莎：NFER-Nelson。纳尔逊，H. E、& Willison，J.（1991）.全国成人阅读测试（NART）。温莎：NFER-Nelson。）和韦氏成人阅读测验（WTAR; Wechsler，D.（2001年）的第10页。Wechsler成人阅读测验（WTAR）圣安东尼奥，得克萨斯州：心理公司。我们的研究结果表明，阅读测试提供了最可靠和精确的WAIS-IV全量表智商的估计，虽然人口统计数据的增加提供了适度的改善。然而，我们观察到相当大的变异性NART/WTAR评分和个人WAIS-IV指数之间的相关性，这表明特别有用的估计更多的结晶病前能力（由口头理解和一般能力指数）相对于流体能力（工作记忆和知觉推理指数）。我们讨论并鼓励开发新的方法来改善神经系统患者的认知能力的发病前估计。
To evaluate impact of neurological injury on cognitive performance it is typically necessary to derive a baseline (or "premorbid") estimate of a patient's general cognitive ability prior to the onset of impairment. In this paper, we consider a range of common methods for producing this estimate, including those based on current best performance, embedded "hold/no-hold" tests, demographic information, and word reading ability. Ninety-two neurologically healthy adult participants were assessed on the full Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV; Wechsler, D. (2008). Wechsler Adult Intelligence Scale (4th ed.). San Antonio, TX: Pearson Assessment.) and on two widely used word reading tests: National Adult Reading Test (NART; Nelson, H. E. (1982). National Adult Reading Test (NART): For the assessment of premorbid intelligence in patients with dementia: Test manual. Windsor: NFER-Nelson.; Nelson, H. E., & Willison, J. (1991). National Adult Reading Test (NART). Windsor: NFER-Nelson.) and Wechsler Test of Adult Reading (WTAR; Wechsler, D. (2001). Wechsler Test of Adult Reading: WTAR. San Antonio, TX: Psychological Corporation.). Our findings indicate that reading tests provide the most reliable and precise estimates of WAIS-IV full-scale IQ, although the addition of demographic data provides modest improvement. Nevertheless, we observed considerable variability in correlations between NART/WTAR scores and individual WAIS-IV indices, which indicated particular usefulness in estimating more crystallised premorbid abilities (as represented by the verbal comprehension and general ability indices) relative to fluid abilities (working memory and perceptual reasoning indices). We discuss and encourage the development of new methods for improving premorbid estimates of cognitive abilities in neurological patients.
