Such underestimation could adversely affect brain injury rehabilitation and treatment planning as patients could be prematurely determined to have returned to baseline and discontinued from care. These include best performance (Lezak, Citation1995), hold/no-hold (Wechsler, Citation1958), demographics (e.g., Barona, Reynolds, & Chastain, Citation1984; Crawford & Allan, Citation1997), reading ability (e.g., Nelson, Citation1982; Nelson & Willison, Citation1991; Wechsler, Citation2001), and combinations thereof (e.g., Crawford, Nelson, Blackmore, Cochrane, & Allan, Citation1990; Vanderploeg, Schinka, & Axelrod, Citation1996). Estimated premorbid IQ scores from the WTAR were similar to LOFT scores and were in the average or high average range for both the HC and CV-risk groups. 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). In contrast, those participants with mTBI did not significantly differ from healthy controls and both the mTBI and control groups demonstrated stability on the WTAR over time. The .gov means its official. . Correlation coefficients, although significant, were relatively small, even though statistical power (1 - ) in all cases exceeded .8 (two-tailed). National Library of Medicine Our findings indicate that reading tests provide the most reliable and precise estimates of WAIS-IV full-scale IQ, although the addition of demographic data provides modest improvement. (1991). Comparison of models of premorbid IQ estimation using the TOPF, OPIE-3, and Barona equation, with corrections for the Flynn effect. Proper TOPF scoring procedures are presented. Both TBI groups experienced at least some degree of initial cognitive impairment on traditional neuropsychological measures (TMT, CVLT-II) with notable improvement over the first year. It was hypothesized that performance on these measures would improve over time whereas the WTAR remained stable. WebThe Test of Premorbid Functioning Score Report can be generated with a maximum of four assessment records. FSIQ, WAIS-IV full-scale IQ; Note: 1=included in model; 0=excluded from model. 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. 2021 Sep-Oct;28(5):564-572. doi: 10.1080/23279095.2019.1664547.

Although both TBI groups improved over time, those with msevTBI continued to be impaired relative to controls at 1 year post-injury. Brasure, M., Lamberty, G. J., Sayer, N. A., Nelson, N. W., Macdonald, R., Ouellette, J., et al. 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. For example, both the NART and the WTAR use equal weightings for each of the 50-test items comprising each test. The .gov means its official. The raw score can be transformed to an age-adjusted standard score, which is used to predict IQ (M = 100; SD = 15). WebTest of Premorbid Functioning estimates an individual's pre-morbid cognitive and memory functioning. WAIS-IV, Wechsler Adult Intelligence Scale Fourth Edition. Performance across the WAIS-IV measures also differed significantly [F(3, 272.59Footnote1)=3.12, p=.026], although pairwise comparisons revealed that only one effect remained significant following Bonferroni correction, with FSIQ higher than PSI (p=.043). Moreover, the msevTBI group's performance improved from baseline (M=23.4; SD=13.20) to 12 months post-injury (M=26.88; SD=12.05), t(39)=2.19, p<.05, d=.35.

Learn about a patient referred for neuropsychological testing when a neurological evaluation and brain imaging were inconclusive. All TOPF scores were significantly correlated with WAIS-IV FSIQ scores (range r = 0.56-.73). 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. Includes scoring and reporting digital-only when used separately from WMS-IV. The WTAR provides an accurate estimate of premorbid intellectual functioning in a variety of cognitively impaired populations (Wechsler, 2001).

Of note, within the msevTBI group, change in raw WTAR score was significantly correlated with change in all three neuropsychological variables. Purpose. Comparison of models of premorbid IQ estimation using the TOPF, OPIE-3, and Barona equation, with corrections for the Flynn effect. ToPF and WAIS-IV scores did not differ by injury severity. Moreover, the msevTBI group had a significant improvement in WTAR performance over the 1-year period. The appropriateness of a given approach is likely to depend on the patient under investigation, but those based on reading ability/word knowledge are among the most widely employed, particularly in North America, UK and Australia (e.g., Crawford, Stewart, Cochrane, Parker, & Besson, Citation1989; Mathias, Bowden, & Barrett-Woodbridge, Citation2007; Skilbeck, Dean, Thomas, & Slatyer, Citation2013). Causes of TBI for the patient sample included: 65% motor vehicle collision (n=54), 13% falls (n=17), 2% assaults (n=3), and 11% other (n=9). Healthy adult controls (n=52) were recruited through local advertisements and selected to match participants with TBI on demographic variables of age, sex, ethnicity, and education. Such tests also require neuropsychological assessment skills/training, take time to administer, and can contribute to patient fatigue. Our overall aim was to establish which method, or combination of methods, offers the most accurate prediction of WAIS-IV FSIQ and its constituent indices. Riley and Simmonds (2003) administered the NART to individuals with severe head injury while they were within the first year of recovery and again after a year. Federal government websites often end in .gov or .mil. Estimating Premorbid Ability in Rehabilitation Patients Using the Test of Premorbid Functioning and Wide Range Achievement Test-Fourth Edition. In the present study, for example, NART and WTAR performance was only moderately sensitive to current working memory and perceptual reasoning ability, implying limited utility of such tests for estimating premorbid nonverbal/fluid intelligence in neurological patients. Categories based on occupational status and education, for example, are arguably too coarse to provide an accurate premorbid IQ for a specific individual. This study aimed to compare 3 common measures and assess their accuracy: the Test of Premorbid Functioning (TOPF), Oklahoma Premorbid Intelligence Estimate (OPIE-3), and what is commonly referred to as the Barona equation. The site is secure. Permission is granted subject to the terms of the License under which the work was published. Our findings suggest that tests of word reading/vocabulary knowledge provide the most reliable and precise estimates of WAIS-IV performance, and previous work indicates that their utility for predicting premorbid IQ holds in a range of neurological conditions (Bright et al., Citation2002). These findings support previous literature suggesting that the WTAR is a stable estimate of premorbid IQ following mild but not severe TBI (Mathias et al., 2007). Scaled scores were higher for Information in comparison with Digit Span (p=.046), Coding (p=.041) and Similarities (p<.01), and for Block Design in comparison to Similarities (p=.038). 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.

Finally, future research should have a longer follow-up period to determine at what point word-reading ability stabilizes for individuals with msevTBI and if they ever reach the estimated IQ of healthy controls. Typically, school leaving age of 16 corresponds to level I, 18 to level II; levels III and IV included participants currently undertaking that level of study. WebThe Test of Premorbid Functioning enables clinicians to estimate an individuals level of cognitive and memory functioning before the onset of injury or illness. 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. Due to the relatively small sample size, we were unable to separate the mild and the complicated mild TBI groups or the moderate and severe TBI groups. However, there are few published methods currently available that have been standardised against the most recent revision of the Wechsler Adult Intelligence Scale (WAIS-IV; Wechsler, Citation2008).

These tests should not be used to infer premorbid processing speed. Demographic and clinical characteristics of study participants. Participants were initially assessed at 36 months post-injury and again 6 months later. Hsieh et al (2014) identified two cutoffs: 1) 25/30 has both high sensitivity and specificity and 2) 21/30 is almost NART and WTAR raw error scores exhibited a large correlation [r(90)=.88, p<.001] and both measures also showed significant negative correlations with age [r(90)=.64 and .54, p <.001, for NART and WTAR respectively]. Data were retrospectively analyzed on persons with TBI (n=83) who were enrolled from the University of Alabama at Birmingham (UAB) hospital system between 2007 and 2011 as part of a larger NIH-funded longitudinal study investigating medical decision making in TBI (Triebel et al., 2012). 2020 Jan;34(1):43-52. doi: 10.1037/neu0000569.

Estimating premorbid intelligence in persons with traumatic brain injury: an examination of the Test of Premorbid Functioning. However, given that all three groups had similar demographic profiles and that those with msevTBI experienced improvement over time, there is no reason to suspect that the msevTBI group was less intelligent than other groups prior to injury.

Results The WTAR was co-normed with the Wechsler Adult Intelligence scale, Third Edition (WAIS-III; Wechsler, 1997). To the authors knowledge, no study has assessed whether the WTAR can provide a stable estimate of premorbid intellectual ability in the first 12 months following mild TBI (mTBI) or moderate/severe TBI (msevTBI) in comparison with healthy controls.

Seventeen individuals with mTBI had evidence of structural brain changes (such as contusions, subdural hematoma, or diffuse axonal injury) on cranial magnetic resonance imaging (MRI) or computed tomography (CT) scan. This has been a consistent problem with literature in the field and should be addressed in future studies with both pre- and post-injury intelligence testing. Word pronunciation tests are the most commonly used hold test and have been used to estimate premorbid intelligence in a wide variety of clinical populations (Dwan, Ownsworth, Chambers, Walker, & Shum, 2015; Hanks et al., 2008; McGurn et al., 2004). To evaluate impact of neurological injury on cognitive performance it is typically necessary to derive a baseline (or premorbid) estimate of a patients general cognitive ability prior to the onset of impairment. The British NART, WTAR and WAIS-IV were then administered (in that order) according to standardised instructions. Careers.

Procedures were approved by the University ethics panel and followed the tenets of the Declaration of Helsinki. Additionally, WTAR-estimated intelligence was similar to that predicted by the Crawford and Allan (1997) demographic equation. Furthermore, the calculation of a premorbid IQ estimate on the basis of a subset of the same tests used to calculate current IQ suggests a psychometric flaw, in which there is very likely to be high predictive accuracy in healthy populations but questionable validity when applied in neurological patients. It is a view-only digital file. Their study found a modest relationship between reading performance and indices of injury severity. Written informed consent was obtained from each participant or a legally authorized representative. Individuals with penetrating brain injuries (e.g., gunshot wound) were excluded from the study. The raw score (total number correct) can be converted into two estimates of premorbid IQ.

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. Potential differences in demographic characteristics between control and TBI groups were analyzed using one-way analysis of variance (ANOVA; age, years of education) or Pearson's chi-square tests (gender, race). Bold values indicate significance at p < .05. The two variable equations are as follows: NART: estimated FSIQ=141.126 (1.26 NART error) (.236 age)WTAR: estimated FSIQ=111.553 (1.087 WTAR error)+(2.976 education)NART+WTAR: estimated FSIQ=136.839 (.720 (NART+WTAR error)) (.212 age).
