Correlations with PSI were comparatively poor, indicating that estimation of basic information processing speed should not be inferred on the basis of NART or WTAR scores.

The basic score on any test is the raw score, which is simply the Overall, there was a greater range in WTAR scores among participants with msevTBI compared with those with milder head injury and healthy controls. The control, mTBI, and msevTBI groups did not differ with regard to age, education, or race. Patients were excluded if they had received substance abuse treatment within 1 year of enrollment (per patient/family report) or had a preexisting diagnosed central nervous system disorder, developmental disorder, or severe psychiatric disorder. 1R01HD053074]. [1] Their findings suggest that severe TBI may negatively affect WTAR performance in the first year following injury. However, there was a statistically significant interaction between time and group, F(2, 132)=4.31, p<.05, partial eta2=.061, on WTAR performance. This was the case for equations incorporating NART, WTAR, and the sum of these test scores (Table 5). Phone: +1 (800) 627-7271 Older adults with no cognitive complaints obtained a mean score of 23 ( SD = 2.4) ( Rabin et al., 2007 ); thus, these values can be used to convert the raw score to a z-score. Bethesda, MD 20894, Web Policies A year later, 15% of individuals with msevTBI continued to have a WTAR-predicted IQ 1.5 SDs below the mean. (PDF) Investigating the Test of Premorbid Functioning (TOPF) in For example, the shared variance (r2) between Vocabulary and Block Design scaled scores was less than 10%, rising to 12% for the combined hold measure. 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). We discuss and encourage the development of new methods for improving premorbid estimates of cognitive abilities in neurological patients. doi: 10.1002/trc2.12348. . Our results are also consistent with other TBI studies, which used hold measures comparable to the WTAR, such as the National Adult Reading Test (NART) and the Reading subtest from the Wide Range Achievement Test (WRAT).

Further analysis of the distribution of predicted IQ scores revealed that 25% of participants with msevTBI fell greater than 1.5 SDs below the normative mean 1 month after injury, in comparison with only 4.7% of those with mTBI and 0% of healthy controls.

Overall, the level of unexplained variance in performance across hold and no-hold tests in our neurologically healthy sample cautions against the viability of using this method for accurately predicting premorbid ability in cognitively impaired patients. Can be used in forensic evaluations to evaluate suspected loss of cognitive functioning. The current study assessed whether there was a dose-related relationship between injury severity and word-reading ability immediately after injury. TOPF Test of Premorbid Functioning - Pearson clinical Performance on the WTAR was also compared with neuropsychological measures known to be sensitive to the effects of head injury in order to assess the stability of word reading relative to other cognitive domains likely to display improvement during the post-acute phase. Wechsler Adult Intelligence Scale (4th ed.). Written informed consent was obtained from each participant or a legally authorized representative. By extension, the remaining core subtests measure no-hold abilities (i.e., those most susceptible to neurocognitive impairment), but the most commonly used are Block Design, Digit Span, Arithmetic and/or Coding (Groth-Marnat & Wright, Citation2016; Wechsler, Citation1958). The WTAR (Wechsler, 2001)comprises 50 words with irregular pronunciations that participants read aloud. . Such tests also require neuropsychological assessment skills/training, take time to administer, and can contribute to patient fatigue.

Figure 2. Conclusions: The Test of Premorbid Functioning (TOPF; Pearson, Citation2009; Wechsler, Citation2011), proposed as a replacement for the WTAR, has been standardised against WAIS-IV, but has not been widely adopted to date (at least for research purposes). Point-by-point comparison against predicted WAIS and WAIS-R IQs included in the British NART-R test manual shows similar estimates at the high end of the distribution (but lowest for WAIS-IV), with estimates at the lower end falling between the WAIS (higher) and WAIS-R (lower) FSIQ estimates (Figure 2). Such variability in neurologically healthy participants renders estimation of premorbid IQ using a straightforward best performance approach problematic, and likely to produce markedly inflated predicted scores. All participants were recruited and tested between 2013 and 2016, in a UK university setting. With large samples, however, reliable stimulus-specific coefficients can be computed in which the predictive value of each stimulus is individually weighted. Spreen and Strauss (2006) noted that WTAR scores are highly correlated with measures of verbal IQ (r=.75) and full scale IQ (r=.73). Their group reported stable performance on the WTAR despite consistent improvement on other cognitive measures known to be sensitive to the effects of head injury. B., et al. Two of these measures were chosen for analyses as they assess areas of cognition known to be sensitive to the effects of head injury (Rabinowitz & Levin, 2014): Trail Making Test (TMT), Part A and B (Reitan & Wolfson, 1993), and the California Verbal Learning Test-II (CVLT-II) Trials 15 Total (Delis, Kramer, Kaplan, & Ober, 2000). Additionally, there was a positive correlation between the WTAR and change in these measures for those with msevTBI, providing additional evidence that the word-reading ability is influenced by cognitive recovery. However, clinicians should be cautious when interpreting performance on word reading measures in the early stages of moderate-to-severe TBI recovery as the predicted IQ may underestimate true premorbid intellectual functioning for at least the first year following injury. Raw scores for both versions of the WRAT are converted to age the WRAT-4 Reading subtest has not been formally established as an estimate of premorbid functioning in the research literature; however, its substantial overlap with the WRAT-3 and its shared validation process suggests that the two versions of the test are similar Test of Premorbid Functioning - UK Version (TOPF-UK) Would you like email updates of new search results? de Erausquin GA, Snyder H, Brugha TS, Seshadri S, Carrillo M, Sagar R, Huang Y, Newton C, Tartaglia C, Teunissen C, Hkanson K, Akinyemi R, Prasad K, D'Avossa G, Gonzalez-Aleman G, Hosseini A, Vavougios GD, Sachdev P, Bankart J, Mors NPO, Lipton R, Katz M, Fox PT, Katshu MZ, Iyengar MS, Weinstein G, Sohrabi HR, Jenkins R, Stein DJ, Hugon J, Mavreas V, Blangero J, Cruchaga C, Krishna M, Wadoo O, Becerra R, Zwir I, Longstreth WT, Kroenenberg G, Edison P, Mukaetova-Ladinska E, Staufenberg E, Figueredo-Aguiar M, Ycora A, Vaca F, Zamponi HP, Re VL, Majid A, Sundarakumar J, Gonzalez HM, Geerlings MI, Skoog I, Salmoiraghi A, Boneschi FM, Patel VN, Santos JM, Arroyo GR, Moreno AC, Felix P, Gallo C, Arai H, Yamada M, Iwatsubo T, Sharma M, Chakraborty N, Ferreccio C, Akena D, Brayne C, Maestre G, Blangero SW, Brusco LI, Siddarth P, Hughes TM, Zuiga AR, Kambeitz J, Laza AR, Allen N, Panos S, Merrill D, Ibez A, Tsuang D, Valishvili N, Shrestha S, Wang S, Padma V, Anstey KJ, Ravindrdanath V, Blennow K, Mullins P, ojek E, Pria A, Mosley TH, Gowland P, Girard TD, Bowtell R, Vahidy FS.

Epub 2019 Aug 15. The WTAR was co-normed with the Wechsler Nevertheless, the scarcity of very low WTAR scores in our sample suggests that these lower FSIQ estimates should be interpreted with caution. 2022 Sep 22;8(1):e12348. For example, performance on tests such as the NART and WTAR is unlikely to be entirely insensitive to neurological impairment, and the degree of sensitivity is likely to differ from one patient and/or condition to another.
