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. (JINS, 2005,
