This study was designed to examine the effect of various criterion measures on the classification accuracy of Trial 1 of the Test of Memory Malingering (TOMM-1), a free-standing performance validity test (PVT). Archival data were collected from a case sequence of 91 (MAge = 42.2 years; MEducation = 12.7) patients clinically referred for neuropsycho...

This study was designed to introduce and validate a forced choice recognition trial to the Rey Complex Figure Test (FCR RCFT ). Healthy undergraduate students at a midsized Canadian university were randomly assigned to the control (n = 80) or experimental malingering (n = 60) conditions. All participants were administered a brief battery of neurops...

Objective: To replicate previous research on Conners' Continuous Performance Test - Second Edition subscales as performance validity tests (PVTs) in children. Method: Classification accuracy for the Omissions (OMI), Hit Reaction Time (HRT), and Perseverations (PER) subscales was computed for 414 children and adolescents. Results: Overall, OMI,...

Objective: This study investigated the potential of alternative, more liberal cutoffs on Trial 2 of the Test of Memory Malingering (TOMM) to improve classification accuracy relative to the standard cutoffs (≤44). Method: The sample consisted of 152 patients (49.3% male) with psychiatric conditions (PSY) and traumatic brain injury (TBI) referred for...

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...

Past studies have examined the ability of the Wisconsin Card Sorting Test (WCST) to discriminate valid from invalid performance in adults using both individual embedded validity indicators (EVIs) and multivariate approaches. This study is designed to investigate whether the two most stable of these indicators—failures to maintain set (FMS) and the...

In previous research, several subscales of Conners’ CPT-II were found to be useful as performance validity tests (PVTs) when administered to adults with traumatic brain injury (TBI). Furthermore, invalid response sets were associated with inflated scores on several CPT-II scales. The present study proposed to investigate whether these findings woul...

Aboriginal children in Canada are at high risk of fetal alcohol spectrum disorder (FASD) but there is little research on the cognitive impact of prenatal alcohol exposure (PAE) in this population. This paper reviews the literature on parent report of executive functioning in children with FASD that used the Behavior Rating Inventory of Executive Fu...

Scores on the Complex Ideational Material (CIM) were examined in reference to various performance validity tests (PVTs) in 106 adults clinically referred for neuropsychological assessment. The main diagnostic categories, reflecting a continuum between neurological and psychiatric disorders, were epilepsy, psychiatric disorders, postconcussive disor...
