INTRODUCTION: It is common to use normative adjustments based on race to maintain accuracy when interpreting cognitive test results during neuropsychological assessment. However, embedded performance validity tests (PVTs) do not adjust for these racial differences and may result in elevated rates of false positives in African American/Black (AA) samples compared to European American/White (EA) samples. METHODS: Veterans without Major Neurocognitive Disorder completed an outpatient neuropsychological assessment and were deemed to be performing in a valid manner (e...

OBJECTIVE: Novel performance validity tests (PVTs) for the Hopkins Verbal Learning Test-Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R), derived from infrequent patterns of performance (IPOP), were developed to examine invalid memory performance while reducing false positive misclassification. To examine their classification accuracy, these indicators were compared to several existing embedded PVTs in a mixed clinical sample. METHOD: A chart review was completed for 75 adult outpatients (Mean Age = 52, Range = 19-85) referred to an academic medical center outpatient clinic for neuropsychological evaluation...

The Memory Validity Profile (MVP) and Medical Symptom Validity Test (MSVT) are performance validity tests (PVTs) used to identify potential noncredible test performance during psychological evaluations. This study sought to examine the agreement between MVP and MSVT pass rates, as well as to determine if there are differences in MVP pass rates when using the cutoff score in the MVP professional manual compared with the experimental cutoff score of <31. Via retrospective review of records, 106 clients at a private neuropsychological clinic who had been given the MVP and the MSVT were identified...

Objective: This study examined disability-related factors as predictors of PVT performance in Veterans who underwent neuropsychological evaluation for clinical purposes, not for determination of disability benefits. Method: Participants were 1,438 Veterans who were seen for clinical evaluation in a VA Medical Center's Neuropsychology Clinic. All were administered the TOMM, MSVT, or both. Predictors of PVT performance included (1) whether Veterans were receiving VA disability benefits ("service connection") for psychiatric or neurological conditions at the time of evaluation, and (2) whether Veterans reported on clinical interview that they were in the process of applying for disability benefits...

A functional multi-scale vascular network can promote 3D engineered tissue growth and improve transplantation outcome. In this work, by using a combination of living cells, biological hydrogel, and biodegradable synthetic polymer we fabricated a biocompatible, multi-scale vascular network (MSVT) within thick, implantable engineered tissues. Using a templating technique, macro-vessels were patterned in a 3D biodegradable polymeric scaffold seeded with endothelial and support cells within a collagen gel. The lumen of the macro-vessel was lined with endothelial cells, which further sprouted and anastomosed with the surrounding self-assembled capillaries...

There is a need to develop performance validity tests (PVTs) that accurately identify those with severe cognitive decline but also remain sensitive to those suspected of invalid cognitive testing. The TOMM1 Discrepancy Index (TDI) attempts to address both of these issues. Veterans diagnosed with dementia ( n  = 251) were administered TOMM1 and the MSVT in order to develop the TDI (TOMM1 percent correct minus MSVT Free Recall percent correct). Cut offs based on the dementia sample were then used to identify those in the non-dementia sample ( n  = 1,226) suspected of invalid test performance ( n  = 401)...

To assess noncredible performance on the NIH Toolbox Cognitive Battery (NIHTB-CB), we developed embedded validity indicators (EVIs). Data were collected from 98 adults (54.1% female) as part of a prospective multicenter cross-sectional study at 4 mild traumatic brain injury (mTBI) specialty clinics. Traditional EVIs and novel item-based EVIs were developed for the NIHTB-CB using the Medical Symptom Validity Test (MSVT) as criterion. The signal detection profile of individual EVIs varied greatly. Multivariate models had superior classification accuracy...

Pediatric neuropsychologists are increasingly recognizing the importance of performance validity testing during evaluations. The use of such measures to detect insufficient effort is of particular importance in pediatric epilepsy evaluations, where test results are often used to guide surgical decisions and failure to detect poor task engagement can result in postsurgical cognitive decline. The present investigation assesses the utility of the Medical Symptom Validity Test (MSVT) in 104 clinically referred children and adolescents with epilepsy...
