The present study compared executive dysfunction among children with attention-deficit/hyperactivity disorder (ADHD) after traumatic brain injury (TBI), also called secondary ADHD (S-ADHD), pre-injury ADHD and children with TBI only (i.e., no ADHD). Youth aged 6-16 years admitted for TBI to five trauma centers were enrolled (n=177) and evaluated wi...

The Beck Depression Inventory – Second Edition (BDI-II) and the Beck Anxiety Inventory (BAI) are two commonly used self-report screeners for depression and anxiety, respectively. The present study aimed to determine the level of agreement between the BDI-II/BAI and the Personality Assessment Inventory (PAI), a more extensive measure of emotional an...

Cutoffs on performance validity tests (PVT) may have to be adjusted based on demographic factors to minimize bias. Although research in this area is minimal, previous work found a gender effect on the Recognition Memory Test (RMT; Kim et al., 2010). The current study aimed to replicate these gender differences on the WCT, as well as examine the eff...

The Stroop paradigm has many variants. Due to its potential to function as an embedded validity indicator, this study was designed to develop performance validity indicators embedded within the Delis-Kaplan Executive Function Systems (D-KEFS) version of the Stroop task.

Feigned attention-deficit/hyperactivity disorder (ADHD) in adults is a significant issue in clinical settings, particularly regarding academic accommodations and access to controlled substances by university students. This article discusses the definitions, base rates, external incentives, psychometric detection strategies, and ethical implications...

Acquired brain injuries (ABI; brain injuries caused by trauma, infection, disease, anoxia,strokes, tumours, and surgeries) are widely prevalent and result in profound consequences, including clinically significant symptoms of depression and anxiety. Cognitive behavioural therapy (CBT) is an empirically validated treatment for depression and anxiety...

This study was designed to develop performance validity indicators embedded within the Delis-Kaplan Executive Function Systems (D-KEFS) version of the Stroop task. Archival data from a mixed clinical sample of 132 patients (50% male; MAge= 43.4; MEducation= 14.1) clinically referred for neuropsychological assessment were analyzed. Criterion measure...

Objective The Forced Choice Recognition (FCR) trial of the California Verbal Learning Test—Second Edition (CVLT-II) was designed to serve as a performance validity test (PVT). The present study was designed to compare the classification accuracy of a more liberal alternative (≤15) to the de facto FCR cutoff (≤14). Method The classification accurac...

A link between noncredible responding and low scores on the Grooved Pegboard Test (GPB) is well documented in the clinical literature. However, no specific validity cutoffs have emerged in previous research. This study was designed to examine the classification accuracy of various demographically adjusted cutoffs on the GPB against established meas...

The article reviews systemic and context-specific challenges of psychoeducational assessment using two case studies: a 19-year-old woman with feigned attention-deficit/ hyperactivity disorder and a 50-year-old man with genuine dyslexia. These cases demonstrate that providing a thorough evaluation of performance validity is an essential component of...

This study was designed to examine the clinical utility of critical items within the Recognition Memory Test (RMT) and the Word Choice Test (WCT). Archival data were collected from a mixed clinical sample of 202 patients clinically referred for neuropsychological testing (54.5% male; mean age ¼ 45.3 years; mean level of education ¼ 13.9 years). The...

This study was designed to examine the effect of language proficiency and level of verbal mediation on failure rates on performance validity tests (PVTs). PVTs with high and low verbal mediation were administered to 80 healthy community-dwelling English-Arabic bilinguals. Digit Span and Animal Fluency were administered in both English and Arabic, i...

The examination of test effort is an integral part of neuropsychological evaluation, as the validity of assessment findings is compromised if a patient fails to put forth an effortful performance. The Test of Memory Malingering (TOMM), a forced-choice technique for the detection of poor effort, is widely utilized and has been shown to be sensitive...
