Abstract

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 ≥ .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.
