Diagnostic neuropsychological assessment requires the clinician to estimate a patient's premorbid abilities. Word reading tests, such as the National Adult Reading Test-Revised (NART-R), provide reasonably accurate estimates of premorbid IQ, but their capacity to benchmark other premorbid cognitive abilities remains unclear. In this extension of an earlier report, we administered the NART-R, an abbreviated Wechsler Adult Intelligence Scale (WAIS-R or WAIS-III), and 26 other cognitive measures to 322 reasonably healthy adults. While NART-R performance correlated robustly (rs > or = .72) with concurrent Verbal and Full Scale IQ, its correlation with all other cognitive measures was significantly lower. Thus, while it is appealing to use word reading as a proxy for premorbid functioning in other cognitive domains, the NART-R has limited utility for this because it does not predict current performance on other cognitive tests as well as it predicts IQ in healthy adults.
诊断性神经心理学评估要求临床医生评估患者病前的能力。单词阅读测试，如修订版国家成人阅读测试（NART-R），能对病前智商提供较为准确的估计，但它们对其他病前认知能力进行基准评估的能力仍不明确。在这份对早期报告的扩展研究中，我们对322名健康状况尚可的成年人施测了NART-R、韦氏成人智力量表简版（WAIS-R或WAIS-III）以及其他26项认知测量工具。虽然NART-R成绩与同时测得的言语智商和全量表智商有很强的相关性（rs≥0.72），但其与所有其他认知测量工具的相关性显著更低。因此，虽然将单词阅读作为其他认知领域病前功能的替代指标很有吸引力，但NART-R在这方面的效用有限，因为它对其他认知测试当前表现的预测能力不如对健康成年人智商的预测能力。
