The RBANS Effort Index (RBANS-EI; Silverberg, Wertheimer, & Fichtenberg, 2007) is an embedded measure of effort within a frequently employed neuropsychological screening battery. While it has been criticized for inadequate specificity in older non-litigating samples (Hook, Marquine, & Hoelzle, 2009; Warren et al., 2010), the RBANS-EI has yet to be(More)
The Response Bias Scale (RBS) and the Henry-Heilbronner Index (HHI) are two recently developed Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales empirically derived for the purpose of detecting feigned symptom report. Utilizing a veteran sample, the present study examined the utility of these and other MMPI-2 validity scales in(More)
The Digit Span subtest was significantly revised for the WAIS-IV as an ordinal sequencing trial was added to increase working memory demands. The present investigation sought to validate an expanded version of Reliable Digit Span (RDS-R) as well as age-corrected scaled score (ACSS) from the recently revised Digit Span. Archival data were collected from 259(More)
Adults with attention-deficit/hyperactivity disorder (ADHD) are frequently prescribed stimulant medication and eligible for accommodations at work or school that serve as potent incentives to feign ADHD symptoms. The current investigation examined the predictive validity of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales in detecting(More)
OBJECTIVE A survey of neuropsychologists in the Veterans Health Administration examined symptom/performance validity test (SPVT) practices and estimated base rates for patient response bias. METHOD Invitations were emailed to 387 psychologists employed within the Veterans Affairs (VA), identified as likely practicing neuropsychologists, resulting in 172(More)
Structural equation modeling (SEM) is the term for a broadly applicable set of statistical techniques that allow researchers to precisely represent constructs of interest, measure the extent to which data are consistent with a proposed conceptual model, and to adjust for the influence of measurement error. Although SEM may appear intimidating at first(More)
The validity of neuropsychological testing is reliant on examinees putting forth adequate effort, yet it has been asserted that verbal subtests from the Wechsler Adult Intelligence Scales (WAIS) are insensitive to suboptimal effort in comparison to other commonly used neuropsychological measures. The current study examined performance differences on the(More)
Developing embedded indicators of suboptimal effort on objective neurocognitive testing is essential for detecting increasingly sophisticated forms of symptom feigning. The current study explored whether Symbol Span, a novel Wechsler Memory Scale-fourth edition measure of supraspan visual attention, could be used to discriminate adequate effort from(More)
