OBJECTIVE: This study describes the derivation and initial validation evidence of a novel Personality Assessment Inventory (PAI) scale designed to be sensitive to cognitive response bias, as defined by poor performance on performance validity tests (PVTs), in the context of neuropsychological assessment. The Cognitive Bias Scale (CBS) is a ten-item scale that was designed to discriminate between neuropsychological patients who passed or failed PVTs. METHOD: In a sample of 306 consecutive mixed neuropsychological outpatients, the CBS was derived by initially selecting items that significantly discriminated participants who passed and failed two or more PVTs, with further item refinement utilizing Item Response Theory methods...

OBJECTIVE: People living with HIV (PLWH) are at risk for HIV-Associated Neurocognitive Disorders (HAND)/Neurocognitive Impairment (NCI). HIV prevalence in Sub-Saharan Africa (SSA) is high, but neuropsychological screening and testing for NCI among HIV-infected individuals is not done frequently. This systematic review aims to establish how NCI among HIV-infected individuals is being assessed in SSA, if and how the tests are adapted, if norms exist and identify personnel who administer them...

OBJECTIVE: The purpose of this critical review was to evaluate the current state of research regarding the incremental value of neuropsychological assessment in clinical practice, above and beyond what can be accounted for on the basis of demographic, medical, and other diagnostic variables. The focus was on neurological and other medical conditions across the lifespan where there is known risk for presence or future development of cognitive impairment. METHOD: Eligible investigations were group studies that had been published after 01/01/2000 in English in peer-reviewed journals and that had used standardized neuropsychological measures and reported on objective outcome criterion variables...

OBJECTIVE: Prospective memory (PM) is the ability to remember to perform an intention at the appropriate time in the future. It is of primary importance for daily living, and its disruption may impact functional autonomy. To date, few studies have examined PM during the acute phase of mild traumatic brain injury (mTBI), despite the high prevalence of this neurological condition and its potential impact on cognition. METHOD: Twenty mTBI patients (time since injury ranged from 45 to 73 days) and 15 healthy control participants performed the Ecological Test of Prospective Memory (TEMP), a simulated errand task in which participants were required to execute 10 event-based (EB) and five time-based (TB) tasks...

OBJECTIVE: Previous meta-analyses have demonstrated verbal working memory (WM) dysfunction in children and adolescents with attention deficit/hyperactivity disorder (ADHD); however, the findings are inconsistent. The main objective of this meta-analysis was to investigate the performance of children and adolescents with ADHD in the Digit Span Backwards (DSB) subtest from the Wechsler Intelligence Scale for Children or Wechsler Adult Intelligence Scale. We also sought to provide an updated meta-analysis on WM in children and adolescents with ADHD...

OBJECTIVE: Limb apraxia is a motor cognitive disorder that has been mainly studied in patients with dementia or left hemisphere stroke (LHS). However, limb apraxia has also been reported in patients with right hemisphere stroke (RHS), multiple sclerosis (MS) or traumatic brain injury (TBI). This study's aim was to report detailed praxis performance profiles in samples suffering from these different neurological disorders by use of the Diagnostic Instrument for Limb Apraxia (DILA-S). METHOD: 44 LHS patients, 36 RHS patients, 27 patients with dementia, 26 MS and 44 TBI patients participated...

OBJECTIVE: The Word Memory Test (WMT) is a memory-based performance validity test (PVT) with adjusted interpretive criteria (Genuine Memory Impairment Profile; GMIP) proposed for those with cognitive impairment (CI). The GMIP has been criticized for poor discriminability; thus, this study sought to validate the GMIP in a mixed clinical sample. Analyses aimed to demonstrate enhanced detection of invalid neuropsychological test performance while minimizing false positives in a sample including patients with mild CI...

OBJECTIVE: Intentional exaggeration of symptoms is a potential problem in contexts where there are financial incentives to appear disabled. Therefore, calibration of tools to accurately evaluate malingering in these contexts is important. The present study used a criterion groups validation design to determine the ability of the Pain Catastrophizing Scale (PCS) to detect Malingered Pain-Related Disability (MPRD). METHOD: Individuals meeting inclusionary/exclusionary criteria were selected for this study (n = 219) from a larger dataset of chronic pain patients referred for a psychological evaluation...

OBJECTIVE: Assessment of performance validity is an essential component of neuropsychological evaluation. Performance validity indicators contained within cognitive ability measures are particularly advantageous, as they do not require additional test administration time or material, and allow for assessment of validity across multiple cognitive domains over the course of an evaluation. The present study examined the classification accuracy of the Stroop Color and Word Test (Stroop) Word, Color, and Color-Word trials in detecting invalid performance in a mixed forensic and patient sample...

OBJECTIVE: Demographically corrected norms typically account for the effects of age, education, and in some cases, sex and other factors (e.g. race/ethnicity). However, generalizability of normative standards to different countries and ethnic groups is not universal. This study sought to determine whether demographically specific Zambian neuropsychological norms would generalize to a group of South African women. METHOD: 212 English-Xhosa bilingual, South African (SA) women were administered a comprehensive neuropsychological (NP) test battery in either English or Xhosa...
