The raw score can be transformed to an age-adjusted standard score, which is used to predict IQ (M = 100; SD = 15). A comparison of these means in our sample revealed a 22.62 point discrepancy (mean lowest=95.27; highest=117.89). Figure 1. No potential conflict of interest was reported by the author(s). Figure 3 presents scatterplots relating NART error to index scores. A large body of evidence suggests that scores on tests requiring the reading of phonetically irregular words, such as the National Adult Reading Test (NART; Nelson, Citation1982; Nelson & Willison, Citation1991) and Wechsler Test of Adult Reading (WTAR; Wechsler, Citation2001), are highly correlated with measured intelligence in healthy populations (e.g., Bright, Jaldow, & Kopelman, Citation2002; Bright, Hale, Gooch, Myhill, & van der Linde, Citation2016; Crawford, Deary, Starr, & Whalley, Citation2001; Nelson & OConnell, Citation1978), and that reading ability, particularly of irregular words, is resistant to neurological impairment and age-related cognitive decline (for reviews see Franzen, Burgess, & Smith-Seemiller, Citation1997; Lezak, Howieson, Bigler, & Tranel, Citation2012). In our sample, the ToPF/demographic predicted FSIQ underestimated intelligence in a substantial portion of our participants (31%), particularly in those with high average to superior intelligence. Repeatable Battery for the Assessment of Neuropsychological These models were developed to predict scores on particular IQ tests (e.g., The validity of this test depends on WebPremorbidity. An official website of the United States government. Wechsler Test of Adult Reading Several approaches have been devised to estimate premorbid cognitive ability in neurological patients. (PDF) Investigating the Test of Premorbid Functioning (TOPF) in These analyses were followed with Dunnett's comparisons using healthy controls as the reference group. Windsor: NFER-Nelson.) (1991). 8600 Rockville Pike CVLT-II = California Verbal Learning Test, 2nd Edition; mTBI = mild traumatic brain injury; msevTBI = moderate-to-severe traumatic brain injury; WTAR = Wechsler Test of Adult Reading. The range of NART-derived FSIQ predicted values in our sample was 43 IQ points, with our regression analysis revealing that the full distribution of possible predicted values ranged from 78 (50 NART errors) to 126 (0 NART errors). Comparison of WTAR-predicted IQ and neuropsychological test standard scores over time for participants separated by injury severity. Can be used in forensic evaluations to evaluate suspected loss of cognitive functioning. WebObjective: Premorbid estimates of intellectual functioning are a key to assessment. Epub 2019 Nov 13. WebThe most common methods of premorbid function estimation include demographic based approaches (e.g., Barona, Reynolds, & Chastin, 1984), best current performance (e.g., Lezak et al., 2004), reading ability (Willshire, Kinsella, & Prior, 1991), achievement measures (e.g., Baade & Schoenberg, 2004), or a combination of these approaches to create
