performance validity neuropsychology

R John Sawyer, S Marc Testa, Moira Dux
OBJECTIVE: Various research studies and neuropsychology practice organizations have reiterated the importance of developing embedded performance validity tests (PVTs) to detect potentially invalid neurocognitive test data. This study investigated whether measures within the Hopkins Verbal Learning Test - Revised (HVLT-R) and the Brief Visuospatial Memory Test - Revised (BVMT-R) could accurately classify individuals who fail two or more PVTs during routine clinical assessment. METHOD: The present sample of 109 United States military veterans (Mean age = 52...

The most frequently used measures of executive functioning are either sensitive to left frontal lobe functioning or bilateral frontal functioning. Relatively little is known about right frontal lobe contributions to executive functioning given the paucity of measures sensitive to right frontal functioning. The present investigation reports the development and initial validation of a new measure designed to be sensitive to right frontal lobe functioning, the Figure Trail Making Test (FTMT). The FTMT, the classic Trial Making Test, and the Ruff Figural Fluency Test (RFFT) were administered to 42 right-handed men...

Preclinical Alzheimer's disease (AD) is characterized by amyloid deposition in the absence of overt clinical impairment. There is substantial heterogeneity in the long-term clinical outcomes among amyloid positive individuals, yet limited work has focused on identifying molecular factors driving resilience from amyloid-related cognitive impairment. We apply a recently developed predicted gene expression analysis (PrediXcan) to identify genes that modify the association between baseline amyloid deposition and longitudinal cognitive changes...

Introduction: The Hayling Test assesses the components of initiation, inhibition, cognitive flexibility and verbal speed by means of a sentence completion task. This study presents the process of developing the Brazilian version of the Child Hayling Test (CHT) and reports evidence of its content validity. Methods: 139 people took part in the study. The adaptation was performed by seven translators and 12 specialist judges. An initial sample of 92 healthy children was recruited to test a selection of sentences adapted from previous adult and pediatric versions of the instrument, and a sample of 28 healthy children was recruited for pilot testing of the final version...

Neuropsychological assessment is critical in both diagnosis and prognosis of patients with epilepsy. Beyond electrophysiological and anatomical alterations, other factors including different ethnic-cultural and linguistic backgrounds might affect neuropsychological performance. Only a few studies considered migration and acculturation effects and they typically concerned nonclinical samples. The current study aimed at investigating the influence of ethnic background and time spent in Italy on a full neuropsychological battery administered to both Italian and foreign-born patients and at providing a brief interview for obtaining relevant information on each patient's transcultural and language-related history...

OBJECTIVES: The distinction between dementia and mild cognitive impairment (MCI) relies upon the evaluation of independence in instrumental activities of daily living (IADL). Self- and informant reports are prone to bias. Clinician-based performance tests are limited by long administration times, restricted access, or inadequate validation. To close this gap, we developed and validated a performance-based measure of IADL, the Sydney Test of Activities of Daily Living in Memory Disorders (STAM)...

OBJECTIVE: Computerized neuropsychological assessment of concussion has rapidly expanded and Immediate Post-Concussion and Cognitive Testing (ImPACT) is among the most commonly used measures in this domain. ImPACT was primarily developed for use with athletic populations but continues to expand beyond athletics to settings such as the workplace and schools where motivational dispositions may vary. The purpose of the present study was to conduct a systematic review of existing research investigating the prevalence of invalid baseline results and the effectiveness of ImPACT's embedded invalidity indicators in detecting suspect effort...

OBJECTIVE: To examine the validity and reliability of the MMSE-2 for assessing patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) in a Korean population. Specifically, the usefulness of the MMSE-2 as a screening measure for detecting early cognitive change, which has not been detectable through the MMSE, was examined. METHODS: Two-hundred and twenty-six patients with MCI, 97 patients with AD, and 91 healthy older adults were recruited. All participants consented to examination with the MMSE-2, the MMSE, and other detailed neuropsychological assessments...

Elevations on certain Conners' CPT-II scales are known to be associated with invalid responding. However, scales and cutoffs vary across studies. In addition, the methodology behind developing performance validity tests (PVTs) has been challenged for mistaking true impairment for noncredible presentation. Using ability-based tests as a PVT makes clinicians especially vulnerable to this criticism. The present study examined the ability of CPT-II to dissociate effort from impairment in 47 adults clinically referred for neuropsychological assessment...

OBJECTIVE: The Conners' Continuous Performance Test Second Edition (CPT-II) is a measure commonly used in persons with suspected attentional deficits. Our study examined the utility of the CPT-II as a measure of attention in adults with traumatic brain injury (TBI) of varying severity. METHOD: As part of a larger investigation, several measures of cognitive functioning, including the CPT-II, were administered to 30 healthy control participants (HCP), 30 mild TBI participants (M-TBI), and 30 moderate to severe TBI participants (MS-TBI)...

OBJECTIVE: Congenital heart disease (CHD) can affect the developing central nervous system, resulting in neurocognitive and behavioral deficits. Preoperative neurological abnormalities as well as sequelae of the open heart operations required to correct structural abnormalities of the heart contribute to these deficits. There are few studies examining the neurocognitive functioning of adults with CHD. This study sought to investigate multiple domains of neurocognitive functioning in adult survivors of CHD who had childhood cardiac surgery with either moderate or severe disease complexity...

Although it has long been proposed that performance on the Booklet Category Test (BCT) relies on a number of different cognitive abilities, including executive functioning, perceptual reasoning, and memory, only a single total error score is typically derived and interpreted in clinical practice. BCT subscales based on factor analyses of subtest errors or designed specifically to measure specific cognitive domains have been proposed to better assess the multidimensional abilities underlying BCT performance...

Incidental learning (IL) measures provide complementary assessment data reflecting subconscious encoding of information using methods that differ from the procedures of many traditional memory tests. We examined the concurrent validity of an IL measure based on the coding subtest of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Participants included veterans referred for outpatient neuropsychological testing. Performance on the IL procedures correlated more strongly with memory indices than other indices on the RBANS...

BACKGROUND: A multitest approach is optimal for the identification of at-risk driving among older adults. This study examined the predictive validity of a combination of office-based screening tests for on-road driving performance in older adults with and without mild cognitive impairment (MCI)/dementia. METHODS: Forty-four normal control, 20 participants with MCI, and 20 participants with dementia completed a battery of office-based assessments. On-road driving evaluation classified participants as not at-risk (n = 65) or at-risk drivers (n = 19)...

OBJECTIVES: Financial capacity (FC) refers to a set of cognitively mediated abilities related to one's competency to manage propriety and income. Identifying intact from impaired FC in older persons with dementia is a growing concern in geriatric practice, but the best methods to assess this function still need to be determined. This study aims to review data on FC in dementia and on instruments used to assess this domain of capacity. METHODS: Database search was performed in Medline, ISI Web of Knowledge, LILACS and PsycINFO...

Limb apraxia denotes a cognitive impairment of gesture production. Lesion studies in patients with stroke point towards distinct neural processing streams for limb imitation and object-pantomime within left parietal and temporal cortex, respectively. Despite its frequent occurrence as an early symptom in both, Alzheimer's dementia (AD) and behavioural variant frontotemporal dementia (bvFTD), neural correlates of limb apraxia within these patient groups remain unexplored. Using voxel-based morphometry and multiple regression models, associations between limb apraxia and gray matter (GM) volume were investigated in 36 dementia patients (18 AD, 18 bvFTD) in early disease stages...

OBJECTIVE: Given that aging is associated with higher risk of cognitive decline and dementia, improving early detection of cognitive impairment has become a research and clinical priority. The Montreal Cognitive Assessment (MoCA) is a screening instrument used to assess different aspects of cognition. Despite its widespread use, norms adjusted to the sociodemographics of Quebec-French people are not yet available. Such norms are however important because performance on neuropsychological tests varies according to sociodemographic variables including age, sex, and education...

OBJECTIVES: There is no consensus yet on how to determine which patients with cognitive impairment are able to drive a car safely and which are not. Recently, a strategy was composed for the assessment of fitness to drive, consisting of clinical interviews, a neuropsychological assessment, and driving simulator rides, which was compared with the outcome of an expert evaluation of an on-road driving assessment. A selection of tests and parameters of the new approach revealed a predictive accuracy of 97...
