自1982年出版以来，国家成人阅读测试（NART；修订版，NART- r）已成为神经心理学研究中广泛接受的评估发病前智力水平的方法。然而，NART/NART- r性能相对独立于脑损伤的假设近年来受到越来越多的挑战。研究表明，在许多情况下，包括阿尔茨海默症和科萨科夫综合症，阅读能力会下降，导致发病前的智商被低估。在对这些研究的回应中，一些研究人员主张使用人口统计变量作为准确预测病前智力的更合适的基础。我们通过计算基于NART/NART- r、人口统计学变量和两种方法的组合的智商估计值来解决这个问题，并将其与Korsakoff综合征、阿尔茨海默氏症、额叶或颞叶病变患者和健康对照组的当前WAIS/WAIS- r智商进行比较。估计的病前智商在各组之间没有差异，无论是来自NART/NART- r还是人口统计学变量。与人口统计学变量相比，基于NART/NART- r的结果与对照组和患者当前WAIS/WAIS- r智商的相关性更高。将NART评分与人口统计学变量相结合的方程，无论是在患者还是对照组中，都没有显著增加仅由NART解释的智商方差。这些数据为在许多情况下继续使用NART作为对病前智力的有效估计提供了保证。
Since its publication in 1982, the National Adult Reading Test (NART; Revised Version, NART-R) has become a widely accepted method for estimating premorbid levels of intelligence in neuropsychological research. However, the assumption that NART/NART-R performance is relatively independent of brain damage has been increasingly challenged in recent years. In a number of conditions, including Alzheimer dementia and Korsakoff's syndrome, studies have indicated a deterioration in reading ability, leading to an underestimated premorbid IQ. In a reaction to these studies, some researchers have advocated the use of demographic variables as a more suitable foundation for accurately predicting premorbid intelligence. We addressed this issue by calculating IQ estimates on the basis of NART/NART-R, demographic variables, and a combination of the two approaches and by comparing these with current WAIS/WAIS-R IQ in patients with Korsakoff's syndrome, Alzheimer dementia, frontal or temporal lobe lesions, and in healthy controls. Estimated premorbid IQs did not differ across groups, whether derived from NART/NART-R or demographic variables. Those based on NART/NART-R demonstrated higher correlations with cut-rent WAIS/WAIS-R IQ in controls and patients than those derived from demographic variables. An equation combining NART scores with demographic variables did not significantly increase the amount of variance in IQ explained by NART only, either in patients or controls. The data offer reassurance regarding the continued use of NART as a valid estimate of premorbid intelligence in a number of conditions.
