Evaluation of the accuracy of two regression-based methods of estimating premorbid IQ /
Two premorbid IQ estimation procedures were compared in a normal, non-brain impaired sample and a clinical, sample of known brain impaired individuals. The methods used for comparison were the purely demographically based regression index (DI) developed by Barona et al. (1984), and the OPIE equation...

| Summary: | Two premorbid IQ estimation procedures were compared in a normal, non-brain impaired sample and a clinical, sample of known brain impaired individuals. The methods used for comparison were the purely demographically based regression index (DI) developed by Barona et al. (1984), and the OPIE equation, which utilizes demographic information combined with current performance tasks. The data for the normal sample were gathered from the WAIS-R standardization sample of 1880 subjects. The clinical sample was 100 patients with known cognitive impairment who had been referred to a private neuropsychology practice. The DI appeared to provide the most clinical utility as an estimate of premorbid IQ in a cognitively impaired sample. Significant differences between the two methods for specific locations of brain injury were not observed. |
