Predicting premorbid IQ: A revision of the national adult reading test

Blair, Jennifer R., Spreen, Otfried·1989·Clinical Neuropsychologist

Abstract

The National Adult Reading Test (NART) has promise as an assessment tool for the determination of premorbid intellectual function, but needs to be modified for current use in a North American population and validated against the WAIS-R. A revision based on American and Canadian pronunciation rules was prepared. Sixty-six unimpaired subjects were tested with a revised NART and all subtests of the WAIS-R. Demographic variables were also recorded. Correlations between actual VIQ, PIQ and FSIQ, and predicted IQs on the basis of revised NART score were .83, .40, and .75, respectively (all p < .001). Prediction of IQs was more accurate with equations based on revised NART score than with demographic variable prediction equations developed by Barona, Reynolds, and Chastain (1984).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
