A comparison of the NART (restandardized) and the NART-R (revised).
The ability of the National Adult Reading Test (NART; Nelson & Willison, 1991) and the revised NART (NART-R; Crawford, 1990) to estimate IQ was examined in a healthy sample (N = 47) using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) scores as the criterion. Mean estimated IQs from the NART-R were not significantly different from the WAIS-R Full Scale and Performance IQ, but the NART-R significantly overestimated Verbal IQ by 2.5 points. Nelson & Willison's (1991) NART equations significantly overestimated Full Scale and Verbal IQ by 5.3 and 5.5 IQ points respectively. The NART-R had significantly higher correlations with Full Scale and Verbal IQ than the NART.
