The National Adult Reading Test (NART), the Schonell Graded Word Reading Test (SGWRT), and the Wechsler Memory Scale, Form I (WMS) were administered to 65 healthy subjects aged 65 to 89 years. Regression equations were derived which allowed total raw score on the WMS to be predicted from the subject's age and from the number of errors on the NART alone or on the NART and SGWRT combined. The distribution of discrepancies between obtained and predicted WMS scores for each equation did not depart significantly from normality and the percentage of subjects at each discrepancy score is provided. The standard error of prediction for each equation is slightly less than that for predicting WAIS IQ from the NART. Sixteen patients with clinical diagnoses of senile dementia of the Alzheimer type obtained discrepancies as large or larger than the most discrepant 2% of normal subjects. These results suggest that this procedure may provide a brief but effective assessment of cognitive deterioration in the elderly and may be capable of assessing dementia earlier than the NART/WAIS combination.
对65名年龄在65至89岁之间的健康受试者进行了国家成人阅读测试（NART）、肖内尔分级单词阅读测试（SGWRT）和韦氏记忆量表第一版（WMS）。推导出了回归方程，可根据受试者的年龄以及单独在NART上的错误数量或NART与SGWRT合并后的错误数量来预测WMS的总原始分数。每个方程的获得分数与预测分数之间差异的分布与正态分布无显著差异，并给出了每个差异分数下受试者的百分比。每个方程的预测标准误差略小于根据NART预测韦氏成人智力量表（WAIS）智商时的标准误差。16名临床诊断为阿尔茨海默型老年痴呆症的患者所获得的差异与正常受试者中差异最大的2%一样大或更大。这些结果表明，该程序可能为老年人认知衰退提供一种简短而有效的评估，并且可能比NART/WAIS组合更早地评估痴呆症。
