Objective: The D-KEFS Color Word Interference Test (CWIT) is among the most commonly administered measures of verbally mediated processing speed and executive functioning. Previous research suggests that this test may also be sensitive to performance invalidity. We sought to develop new embedded measures of performance invalidity based on multi-condition performance on the CWIT and to evaluate previously proposed embedded measures for performance invalidity on this test. Method: Newly developed and previously proposed embedded measures were evaluated in three samples: a traumatic brain injury (TBI) sample ( N  = 224) classified into psychometrically-defined performance-valid and performance-invalid subgroups; the D-KEFS normative sample ( N  = 1,735); and a Parkinson's disease sample ( N  = 166)...

Objective: This study examined the relationship between tests of performance validity (PVT) and symptom validity (SVT) among claimants undergoing independent neuropsychological evaluations. Previous research comparing PVTs with SVTs has examined symptom validity with respect to overreporting impairment, whereas the current study focused on how PVTs predict underreporting of psychological symptoms and minimization of negative personality characteristics. Method: The sample included 99 claimants presenting with psychological and cognitive complaints who were assessed in a private practice setting...

Objective : To detect cognitive "impairment," neuropsychologists rely on normative data to compare patient performance to "normal" peers. However, the true normality of normative samples may be called into question given the high prevalence of preclinical proteinopathies amongst clinically normal older adults. Given its common use in memory clinics, we aimed to develop a robust California Verbal Learning Test (CVLT) normative standard reflecting only the most cognitively stable sample of older adults available...

Objective: The Clock Drawing Test (CDT) is widely used as a cognitive screening tool. The purpose of this study was to investigate the influence of gender, age, and education on CDT scores in a sample of elderly, community-dwelling adults in China. Methods: The sample was derived from a cross-sectional survey, "The study on the early screening methods for senile dementia." It included Chinese-speaking persons 65 years of age or older with normal cognitive functioning. All the participants underwent neuropsychological assessments, including the Mini-Mental State Examination (MMSE) and the CDT...

Objective : Anosognosia, or lack of awareness of symptoms, is commonly observed in Huntington's disease (HD) using patient/informant-report discrepancy methods. The purpose of this study was to examine the utility of a performance-rating method for assessing awareness of cognitive performance in HD. Method: Persons with manifest HD ( n  = 54) rated their performance on the daily living tests from the Neuropsychological Assessment Battery (NAB) using a bell curve. We also examined patient/informant-report discrepancies of executive functioning (FrSBe) in a subset ( n  = 47) of patients and their informants...

Objective: Embedded validity measures are useful in neuropsychological evaluations but should be updated with new test versions and validated across various samples. This study evaluated Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) Digit Span validity indicators in post-deployment veterans. Method: Neurologically-intact veterans completed structured diagnostic interviews, the WAIS-IV, the Medical Symptom Validity Test (MSVT), and the b Test as part of a larger study. The Noncredible group included individuals who failed either the MSVT or the b Test...

Objective : Older adults commonly experience declines in everyday functioning, the reasons for which are multifactorial. Prospective memory (PM), or remembering to carry out intended actions, can be an executively demanding cognitive process that declines with older age and is independently associated with a variety of everyday functions (e.g. taking medication). This study examined the hypothesis that PM mediates the relationship between older age and poorer everyday functioning. Method : A total of 468 community-dwelling adults (ages 18-75) with a range of medical comorbidities (e...

Objective: The Boston Naming Test, Second Edition (BNT-2) and the Neuropsychological Assessment Battery (NAB) Naming Test are common measures to assess visual confrontation naming ability. The comparably newer NAB Naming Test is a potential alternative to the BNT-2, given the latter's history of criticism. A recent psychometric investigation of the NAB Naming Test demonstrated sufficient reliability and validity in a large clinical sample; however, their study was limited by a lack of ethnic, racial, and language diversity, all of which can impact scores on naming tests...

Objective: Novel technologies have transformed neuropsychological test administration so that research examining the equivalency of computerized versions of traditional tests is needed. This study examined the relationship between psychological symptom severity and performance on the Wisconsin Card Sorting Test (WCST) using the manual versus computerized administration. Method: Eighty-five participants were randomly assigned to the manual or computerized WCST administration and also completed the Dot Counting Test, Depression Anxiety Stress Scales, and Short UPPS-P Impulsive Behavior Scale...

Objective: The current research was conducted to test the prediction that children who have hearing loss and are developing spoken language can perform at the same level as hearing children in an auditory memory span task if actual production of speech is excluded from task requirement. Method: A listen-and-point digit span task and two sub-tests of Wechsler Intelligence Scale for Children-IV (Verbal Digit Span and Matrix Reasoning) were administered to thirty hearing children and thirty-three children with hearing loss...

Objective: Neurofibromatosis type 1 (NF-1) is an autosomal dominant genetic disorder that commonly presents with cognitive impairment and greater rates of learning disorders and academic difficulty compared to the general population. Investigations of neurological and physiological expression of NF-1 in monozygotic twins identified intrapair similarities and differences. Monozygotic twins with NF-1 have been found to have similar IQ scores as well as concordant diagnoses of attention-deficit/hyperactivity disorder and learning disabilities...

Objective: Apathy is a prominent syndrome across neurodegenerative diseases. The Dimensional Apathy Scale (DAS) assesses three apathy subtypes-executive, emotional, and initiation-and is sensitive and valid in amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), and Parkinson's disease. This study describes the development of the brief DAS (b-DAS), which will enable apathy to be swiftly detected in the clinic. Method: 102 ALS and 102 AD patients' previously collected data were used. Mokken analyses were performed on item-level data of each informant/carer-rated DAS subscale (executive, emotional, and initiation) for the initial scale reduction...

OBJECTIVE: Discrimination of patients passing vs. failing the Word Memory Test (WMT) by performance on 11 performance and symptom validity tests (PVTs, SVTs) from the Meyers Neuropsychological Battery (MNB) at per-test false positive cutoffs ranging from 0 to 15%. PVT and SVT intercorrelation in subgroups passing and failing the WMT, as well as the degree of skew of the individual PVTs and SVT in the pass/fail subgroups, were also analyzed. METHOD: In 255 clinical and forensic cases, 100 failed and 155 passed the WMT, at a base-rate of invalid performance of 39...

OBJECTIVE: This research examined affective theory of mind (ToM) differences between university students with and without a history of concussion using the revised Reading the Mind in the Eyes Test (RMET). Although, previous studies have shown that affective ToM is subserved by the ventromedial prefrontal cortex - a region that is vulnerable in head injury - few have examined whether subtle deficits in affective ToM are evident after concussion. Given the RMET's sensitivity to affective deficits following moderate-to-severe traumatic brain injury, the current study examined its validity following concussion and its correlation with related ToM measures and constructs, such as empathy...

OBJECTIVE: Electrical injury (EI) is a distinct subtype of traumatic injury that often results in a unique constellation of cognitive sequelae and unusual sensory experiences due to peripheral nervous system injury that are uncommon in general medical/neurological populations and have been unexplored with the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). METHOD: This study examined performance patterns on MMPI-2-RF validity and substantive scales among 62 EI patients who underwent neuropsychological evaluation, of which 46 demonstrated valid symptom reporting and neurocognitive test performance via multiple independent validity indicators and were retained for analysis...
