RESUMO

Objective: The Boston Naming Test-Second Edition (BNT-2), the "gold-standard" assessment of confrontation naming used to diagnosis disorders such as dementia, includes aculturally insensitive item, the noose. Given calls to stop structural racism in psychology, this study examined changes in scores and performance classification if the noose item were omitted from the BNT-2. Methods: Participants were 291 Black, White, and Latinx adults who were administered the BNT-2 within a comprehensive neuropsychological evaluation. Ethnoracial differences in BNT-2 scores with and without the noose item and percentages of participants answering the noose item incorrectly were investigated. Results: Significant differences were found between ethnoracial groups in BNT-2 raw scores, T-scores, and percentage of participants incorrectly answering the noose item. Follow-up analyses revealed White participants obtained significantly higher raw scores and had significantly fewer participants answer the noose item incorrectly than Black and Latinx groups, who did not differ significantly. For T-scores, Black participants obtained significantly higher scores than White participants who obtained significantly higher scores than Latinx participants. Despite these differences, giving credit for the omitted noose item changed performance classification for only 10 participants (3.4%). Conclusions: Performance classification did not change significantly for the vast majority of a large ethnoculturally diverse sample when giving credit for the noose item as if it were not administered. Therefore, the non-noose BNT-2remains accurate while reducing cultural insensitivity towards Black populations, emphasizing a step in working towards anti-racism and fostering culturally-competent services within psychology.

RESUMO

Use of multiple performance validity tests (PVTs) may best identify invalid performance, though few studies have examined the utility and accuracy of combining PVTs. This study examined the following PVTs in the Advanced Clinical Solutions (ACS) package to determine their utility alone and in concert: Word Choice Test (WCT), Reliable Digit Span (RDS), and Logical Memory Recognition (LMR). Ninety-three veterans participated in clinical neuropsychological evaluations to determine presence of cognitive impairment; 25% of the performances were deemed invalid via criterion PVTs. Classification accuracy of the ACS measures was assessed via receiver operating characteristic curves, while logistic regressions determined utility of combining these PVTs. The WCT demonstrated superior classification accuracy compared to the two embedded measures of the ACS, even in veterans with cognitive impairment. The two embedded measures (even when used in concert) exhibited inadequate classification accuracy. A combined model with all three ACS PVTs similarly demonstrated little benefit of the embedded indicators over the WCT alone. Results suggest the ACS WCT has utility for detecting invalid performance in a clinical sample with likely cognitive impairment, though the embedded ACS measures (RDS and LMR) may have limited incremental utility, particularly in individuals with cognitive impairment.

RESUMO

OBJECTIVE: Premorbid estimates of intellectual functioning are a key to assessment. 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. We also sought to provide appropriate adjustment considering the Flynn effect. METHOD: The sample consisted of a cross-section of 189 outpatient veterans receiving neuropsychological assessment including the TOPF and Wechsler Adult Intelligence Scale, 4th ed. (WAIS-IV). Paired sample t tests assessed differences between IQ models. Correlations for all models and actual WAIS-IV Full Scale IQ (FSIQ) to establish which model best predicted variance in current IQ. Mean differences were evaluated to establish how closely the models approximated WAIS-IV FSIQ. RESULTS: The Barona equation estimated higher premorbid IQ than TOPF Simple Demographics Model; however, differences between the models were nonsignificant after a Flynn effect correction for the Barona equation (.23 IQ points per year). The OPIE-3 correlated with FSIQ but overestimated the FSIQ, demonstrating the Flynn effect. TOPF performance models (include word reading) characterized the variance of IQ scores best, but the Flynn-adjusted Barona equation had the smallest mean difference from the actual WAIS-IV FSIQ of any prediction model. CONCLUSION: Demographic models for premorbid IQ accurately estimate IQ in adult populations when normed on the test used to measure IQ, or when adjusted for the Flynn effect. A Flynn-corrected Barona score provided a more accurate estimation of WAIS-IV FSIQ than the TOPF or the OPIE-3. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

RESUMO

Because the baboon is a model of primary generalized epilepsy, we were interested in mortality of captive animals with a history of witnessed seizures. Causes of natural death were investigated in 46 seizure baboons (SZ) and 78 nonepileptic controls (CTL), all of which underwent a complete pathologic examination at the Southwest Foundation for Biomedical Research (SFBR) in San Antonio. SZ animals died at a younger age than the control baboons (p < 0.001). Almost all epileptic baboons that died suddenly without an apparent cause (SZ-UKN), had pulmonary congestion or edema without evidence of trauma, systemic illness, or heart disease, compared to nine controls (12%) (p < 0.001), most of which demonstrated evidence of a concurrent illness. Serosanguineous bronchial secretions were found in 15 SZ-UKN baboons (58%), but in only three controls (4%) (p < 0.001). Chronic multifocal fibrotic changes in myocardium were noted in only three (12%) of SZ-UKN baboons and one control baboon. Based upon these results, untreated seizures appear to reduce the life expectancy of captive baboons. Sudden unexpected death in epilepsy (SUDEP) may be a common cause of natural death in epileptic baboons.

RESUMO

Many screening tools for detecting cognitive decline require in-person assessment, which is often not cost-effective or feasible for those with physical limitations. The Modified Telephone Interview for Cognitive Status has been used for screening dementia, but little is known about its usefulness in detecting amnestic mild cognitive impairment. Community-dwelling participants (mean age=74.9, mean education = 16.1 years) were administered the Modified Telephone Interview for Cognitive Status during initial screening and subsequently given a multidomain neuropsychological battery. Participants were classified by consensus panel as cognitively normal older adult (noMCI, N=54) or amnestic mild cognitive impairment (N=17) based on neuropsychological performance and Clinical Dementia Rating Scale interview, but independent of Modified Telephone Interview for Cognitive Status score. There was a significant difference between groups in Modified Telephone Interview for Cognitive Status score (t=8.04, P<.01, noMCI range 32-43, mean [SD]=37.4 [2.5], amnestic mild cognitive impairment range 25-37, mean [SD]=31.2 [3.5]). Discriminant function analysis revealed that TICS-M alone correctly classified 85.9% of participants into their respective diagnostic classification (sensitivity=82.4%, specificity=87.0%). Receiver operating characteristics analysis resulted in cutoff score of 34 that optimized sensitivity and specificity of amnestic mild cognitive impairment classification. The Modified Telephone Interview for Cognitive Status is a brief, cost-effective screening measure for identifying those with and without amnestic mild cognitive impairment.

RESUMO

Embedded performance validity tests (PVTs) allow for continuous assessment of invalid performance throughout neuropsychological test batteries. This study evaluated the utility of the Wechsler Memory Scale-Fourth Edition (WMS-IV) Logical Memory (LM) Recognition score as an embedded PVT using the Advanced Clinical Solutions (ACS) for WAIS-IV/WMS-IV Effort System. This mixed clinical sample was comprised of 97 total participants, 71 of whom were classified as valid and 26 as invalid based on three well-validated, freestanding criterion PVTs. Overall, the LM embedded PVT demonstrated poor concordance with the criterion PVTs and unacceptable psychometric properties using ACS validity base rates (42% sensitivity/79% specificity). Moreover, 15-39% of participants obtained an invalid ACS base rate despite having a normatively-intact age-corrected LM Recognition total score. Receiving operating characteristic curve analysis revealed a Recognition total score cutoff of < 61% correct improved specificity (92%) while sensitivity remained weak (31%). Thus, results indicated the LM Recognition embedded PVT is not appropriate for use from an evidence-based perspective, and that clinicians may be faced with reconciling how a normatively intact cognitive performance on the Recognition subtest could simultaneously reflect invalid performance validity.

RESUMO

STUDY OBJECTIVES: The goal of this study was to examine daily associations between sleep and cognition in older adults suffering from insomnia, with or without a history of chronic pain. METHODS: Sixty older adults with insomnia and a history of chronic pain (HxCP; n = 33, mean age = 69.5 years, standard deviation = 7.8) or no history of chronic pain (NCP; n = 27, mean age = 69.7 years, standard deviation = 7.9) completed 14 days of diaries and actigraphy, measuring sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), and sleep quality. Participants completed daily cognitive measures of processing speed (ie, symbol digit modalities test, SDMT), reasoning (ie, letter series), and verbal memory (ie, word list delayed recall). For HxCP and NCP, associations between sleep parameters, daily pain, depressive symptoms (ie, Beck Depression Inventory, Second Edition scores), and daily cognition, controlling for age, and global cognition were examined through multilevel modeling. RESULTS: For HxCP, greater self-reported WASO was associated with worse next-day SDMT performance, whereas greater actigraphic WASO was associated with better next-day SDMT performance. Greater depression was associated with worse daily letter series performance. Greater self-reported WASO and SE were associated with better next-day delayed recall. For NCP, greater self-reported WASO and depression were associated with better daily SDMT performance, whereas worse daily pain was associated with worse SDMT and delayed recall performance. CONCLUSIONS: In older adults with HxCP, improving sleep may benefit lower level cognition, whereas reducing depression may affect higher level cognition. Discrepancies in sleep parameters promote assessment of objective and subjective sleep outcomes when investigating effects of insomnia on cognition.

RESUMO

OBJECTIVE: The aim of the present study was to examine the effects of a brief behavioral intervention for insomnia (BBTi) on sleep parameters, mood, and cognitive functioning in older adults. METHODS: Older adults (aged 65 years or more) underwent four weekly sessions of BBTi or self-monitoring control (SMC). Participants completed 14 days of sleep diaries and actigraphy measuring sleep onset latency (SOL), wake after sleep onset (WASO), total sleep time (TST), sleep efficiency (SE), and sleep quality ratings at baseline, post-treatment, and three month follow-up. Participants also completed mood scales (Geriatric Depression Scale [GDS]; Beck Depression Inventory-II; and State Trait Anxiety Inventory) and neuropsychological testing (measuring global cognition, language, memory, attention and processing speed, and executive function) at the three timepoints. RESULTS: Significant condition (BBTi vs. SMC) x time (baseline vs. post-treatment vs. follow-up) interactions revealed that BBTi improved relative to baseline in sleep diary-reported SOL, WASO, SE, and sleep quality, and these improvements were maintained at follow-up. SMC showed no change in these measures. A main effect of time showed that actigraphy-measured WASO improved from baseline for both BBTi and SMC at post-treatment. A main effect of time revealed that both BBTi and SMC patients endorsed fewer GDS symptoms relative to baseline at post-treatment and follow-up. We observed no change in performance on neuropsychological measures. CONCLUSIONS: A four-week BBTi is an efficacious intervention for reducing insomnia symptoms in older adults. BBTi does not selectively improve mood or cognitive functioning. Future work should examine effects of BBTi on physiological measures of sleep architecture and day-to-day cognition.

RESUMO

OBJECTIVE: Performance-based functional assessment is a critical component of neuropsychological practice. The Texas Functional Living Scale (TFLS) has promise given its brevity, nationally representative norms, and co-norming with Wechsler scales. However, its subscale structure has not been evaluated. The purpose of this study was to evaluate the TFLS in a mixed clinical sample (n = 197). METHOD: Reliability and convergent and discriminant validity coefficients were calculated with neurocognitive testing and collateral reports and factor analysis was performed. RESULTS: The Money and Calculation subscale had the best psychometric properties of the subscales. The evidence did not support solitary interpretation of the Time subscale. A three-factor latent structure emerged representing memory and semantic retrieval, performance and visual scanning, and financial calculation. CONCLUSIONS: This study added psychometric support for interpretation of the TFLS total score and some of its subscales. Study limitations included sample characteristics (e.g., gender ratio) and low power for collateral report analyses.

RESUMO

STUDY OBJECTIVES: Sleep variability is a clinically significant variable in understanding and treating insomnia in older adults. The current study examined changes in sleep variability in the course of brief behavioral therapy for insomnia (BBT-I) in older adults who had chronic insomnia. Additionally, the current study examined the mediating mechanisms underlying reductions of sleep variability and the moderating effects of baseline sleep variability on treatment responsiveness. METHODS: Sixty-two elderly participants were randomly assigned to either BBT-I or self-monitoring and attention control (SMAC). Sleep was assessed by sleep diaries and actigraphy from baseline to posttreatment and at 3-month follow-up. Mixed models were used to examine changes in sleep variability (within-person standard deviations of weekly sleep parameters) and the hypothesized mediation and moderation effects. RESULTS: Variabilities in sleep diary-assessed sleep onset latency (SOL) and actigraphy-assessed total sleep time (TST) significantly decreased in BBT-I compared to SMAC (Pseudo R2 = .12, .27; P = .018, .008). These effects were mediated by reductions in bedtime and wake time variability and time in bed. Significant time × group × baseline sleep variability interactions on sleep outcomes indicated that participants who had higher baseline sleep variability were more responsive to BBT-I; their actigraphy-assessed TST, SOL, and sleep efficiency improved to a greater degree (Pseudo R2 = .15 to .66; P < .001 to .044). CONCLUSIONS: BBT-I is effective in reducing sleep variability in older adults who have chronic insomnia. Increased consistency in bedtime and wake time and decreased time in bed mediate reductions of sleep variability. Baseline sleep variability may serve as a marker of high treatment responsiveness to BBT-I. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: NCT02967185.

RESUMO

INTRODUCTION: Confrontation naming tests are a common neuropsychological method of assessing language and a critical diagnostic tool in identifying certain neurodegenerative diseases; however, there is limited literature examining the visual-perceptual demands of these tasks. This study investigated the effect of perceptual reasoning abilities on three confrontation naming tests, the Boston Naming Test (BNT), Neuropsychological Assessment Battery (NAB) Naming Test, and Visual Naming Test (VNT) to elucidate the diverse cognitive functions underlying these tasks to assist with test selection procedures and increase diagnostic accuracy. METHOD: A mixed clinical sample of 121 veterans were administered the BNT, NAB, VNT, and Wechsler Adult Intelligence Scale-4th Edition (WAIS-IV) Verbal Comprehension Index (VCI) and Perceptual Reasoning Index (PRI) as part of a comprehensive neuropsychological evaluation. RESULTS: Multiple regression indicated that PRI accounted for 23%, 13%, and 15% of the variance in BNT, VNT, and NAB scores, respectively, but dropped out as a significant predictor once VCI was added. Follow-up bootstrap mediation analyses revealed that PRI had a significant indirect effect on naming performance after controlling education, primary language, and severity of cognitive impairment, as well as the mediating effect of general verbal abilities for the BNT (B = 0.13; 95% confidence interval, CI [.07, .20]), VNT (B = 0.01; 95% CI [.002, .03]), and NAB (B = 0.03; 95% CI [.01, .06]). CONCLUSIONS: Findings revealed a complex relationship between perceptual reasoning abilities and confrontation naming that is mediated by general verbal abilities. However, when verbal abilities were statistically controlled, perceptual reasoning abilities were found to have a significant indirect effect on performance across all three confrontation naming measures with the largest effect noted with the BNT relative to the VNT and NAB Naming Test.

RESUMO

OBJECTIVE: This retrospective study investigated the effect of processing speed on confrontation naming performance via five naming tests with varying time components. METHOD: The effect of processing speed, as measured by the Wechsler Adult Intelligence Scale-Fourth Edition Processing Speed Index (PSI), and cognitive impairment were examined using Boston Naming Test, Neuropsychological Assessment Battery Naming Test, Visual Naming Test (VNT), Auditory Naming Test (ANT), and Woodcock-Johnson III Rapid Picture Naming (RPN) performance among a mixed clinical sample of 115 outpatient veterans. RESULTS: PSI scores accounted for 5%-26% of the total variance in naming test performances. Comparison of cognitively impaired versus unimpaired participants found significant differences and medium to large effect sizes (η2 = .08-.20) for all naming measures except ANT tip-of-the-tongue responses. After controlling for the effect processing speed, VNT tip-of-the-tongue responses also became non-significant, whereas significant group differences remained present for all other naming test scores, albeit with notably smaller effects sizes (η2 = .06-.10). CONCLUSIONS: Confrontation naming test performance is related to cognitive processing speed, although the magnitude of this effect varies by the demands of each naming test (i.e., largest for RPN; smallest for VNT). Thus, results argue that processing speed is important to consider for accurate clinical interpretation of naming tests, especially in the context of cognitive impairment.

RESUMO

The study purpose was to compare the diagnostic utility of the Brief Cognitive Status Exam (BCSE) to that of the Mini-Mental State Examination (MMSE) and to develop equated scores to facilitate comparisons. One hundred and eighty-two patients underwent cognitive evaluation and were placed into three groups: dementia (DEM), cognitive impairment, no dementia (CIND), and no cognitive impairment (NCI). One hundred and eighty-two healthy controls from the BCSE standardization sample served as a comparison group. On both measures, the DEM group obtained significantly lower scores than the other two groups, and the CIND group scored significantly lower than the NCI group. The BCSE was more sensitive in all clinical groups, although at extremely low scores, the two tests displayed similar sensitivity. Results indicate the BCSE has diagnostic utility as a cognitive screening measure in a mixed clinical sample and is more sensitive at detecting cognitive impairment, particularly milder levels, than the MMSE.

RESUMO

With the implementation of healthcare reform, it is essential for neuropsychologists to establish themselves as important members of healthcare teams and to work efficiently and effectively. The purpose of this study was to survey the satisfaction of referring providers with neuropsychological services, including turn-around time of reports and their essential elements, within a hospital system that uses electronic medical records. Findings revealed that referral sources are generally satisfied with neuropsychological services and find them valuable. They especially appreciate the neuropsychological report and detailed testing of cognitive and functional abilities and prefer the report within 2 weeks of the patient's appointment. Most find all sections of the report completely essential with the exception of test scores, and most are comfortable with recommendations made by neuropsychologists. With few exceptions, there were no differences among types of referring providers (i.e., physicians, psychologists, and social workers). Future surveys may wish to examine how neuropsychological services affect patient outcomes.

RESUMO

The objective of this study was to model recall and learning on the Auditory Verbal Learning Test using latent growth curve techniques. Participants were older adults recruited for the ACTIVE cognitive intervention pilot. A series of nested models revealed that an approximately logarithmic growth curve model provided optimal fit to the data. Although recall and learning factors were statistically uncorrelated, a fitted multivariate model suggested that initial recall was significantly associated with demographic characteristics but unrelated to health factors and cognitive abilities. Individual differences in learning were related to race/ethnicity, speed of processing, verbal knowledge, and global cognitive function level. These results suggest that failing to recognize initial recall and learning as distinct constructs clouds the interpretation of supraspan memory tasks.

RESUMO

OBJECTIVE: To elucidate the neural mechanisms of depression. BACKGROUND: Despite extensive study, the neurophysiology of the brain's state(s) corresponding to depression remains uncertain. METHODS: HMPAO single photon emission computed tomographic (SPECT) scans were obtained from eight adults diagnosed with major depression resistant to medication (average age 51 years; 4 men) before and immediately after 10 days of 20 Hz repetitive transcranial magnetic stimulation (rTMS) (2000 stimuli/daily 30' treatment). To maximize the likelihood that SPECT scans reflected the state of depression, rather than uncontrolled responses of patients to poorly constrained environments, HMPAO was administered while subjects performed a simple task involving continuous monitoring of the direction of a large arrow on a computer screen and continuously tapping with the left or right index finger according to the direction of the arrow. Mean baseline Beck Depression Inventory (BDI) score was 27.4 (SD = 8.3) and mean posttreatment BDI score was 17.5 (SD = 8.5). RESULTS: Treatment responders (defined by reduction in BDI score of > or = 30%) had significantly less pretreatment blood flow in the left amygdala compared with nonresponders. Responders demonstrated two patterns of change in regional blood flow with treatment: a reduction in orbitofrontal blood flow and/or a reduction in anterior cingulate blood flow. Nonresponders did not demonstrate any regional changes in blood flow with treatment. CONCLUSIONS: These results suggest that there may be either more than one state of depression, or that depression may be associated with more than one pattern of psychologic activity, which in turn defines the depressive experience for individual patients.
