We examined recovery from postconcussion syndrome (PCS) in a series of 285 patients, diagnosed with concussion based on international sport concussion criteria, who received a questionnaire regarding recovery . Of 141 respondents, those with postconcussion symptoms lasting less than 3 months, a positive CT and/or MRI, litigants, and known Test of Memory Malingering (TOMM)-positive cases were excluded, leaving 110 eligible respondents. We found that only 27% of our population eventually recovered, and 67% of those who recovered did so within the first year...

This article describes the development of the Inventory of Problems-29 (IOP-29), a new, short, paper-and-pencil, self-administered measure of feigned mental and cognitive disorders. Four clinical comparison simulation studies were conducted. Study 1 (n = 451) selected the items and produced an index of potential feigning. Study 2 (n = 331) scaled this index to produce a probability score, and examined its psychometric properties. Study 3 tested the generalizability of Study 2's findings with 2 additional samples (ns = 128 and 90)...

As the populations of Western countries become more diverse, the risk of inaccurately generalizing knowledge from majority ethnic groups to minority groups is increasing. However, few of the measures used in forensic assessment are based on normative samples that represent the considerable diversity present in forensic settings. This study examined 4 commonly used measures of feigning: the Dot Counting Test (DCT; Boone, Lu, & Herzberg, 2002); the Miller Forensic Assessment of Symptoms (M-FAST; Miller, 2001); the Test of Memory Malingering (TOMM; Tombaugh, 1996); and a validity scale (atypical responding; ATR) on the Trauma Symptom Inventory-2 (Briere, 2011)...

The present study evaluated the Response Bias scale (RBS), a symptom validity test embedded within the Minnesota Multiphasic Personality Inventory (MMPI)-2 Restructured Form (MMPI-2-RF) that assesses for feigned neurocognitive complaints, in a sample of pretrial incompetent to stand trial (IST) criminal defendants. Additionally, we examined the Improbable Failure (IF) scale, a performance validity test embedded within the Structured Interview of Reported Symptoms, Second Edition (SIRS-2), which similarly assesses for feigned cognitive impairment (FCI)...

INTRODUCTION: The Test of Memory Malingering (TOMM) and the Word Memory Test (WMT) are both performance validity tests (PVTs) that use a two-alternative forced-choice (2AFC) recognition memory format. Several studies have reported that these tests are susceptible to cognitive impairment and that the WMT is more susceptible than the TOMM. The current study explored components of recognition memory (i.e., conscious recollection and familiarity) underlying the TOMM and WMT to identify factors that make them susceptible and resilient to cognitive impairment...

OBJECTIVE: To determine the effectiveness of the Test of Memory Malingering Trial 1 (TOMM1) as a freestanding Performance Validity Test (PVT) as compared to the full TOMM in a criminal forensic sample. METHOD: Participants included 119 evaluees in a Midwestern forensic hospital. Criterion groups were formed based on passing/failing scores on other freestanding PVTs. This resulted in three groups: +MND (Malingered Neurocognitive Dysfunction), who failed two or more freestanding PVTs; possible MND (pMND), who failed one freestanding PVT; and -MND, who failed no other freestanding PVTs...

OBJECTIVE: The current investigation sought to define the relationship between established performance validity tests and measures of memory via a factor analytic strategy first published by Heyanka, Thaler, Linck, Pastorek, Miller, Romesser, & Sim (2015). A Factor analytic approach to the validation of the Word Memory Test and Test of Memory Malingering as measures of effort and not memory. Archives of Clinical Neuropsychology, 30, 369-376. METHOD: The full range of Medical Symptom Validity Test (MSVT) and Non-Verbal Medical Symptom Validity Test (NV-MSVT) subtests were factor analyzed with the memory scales of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in a sample of 346 service members with a history of concussion...

OBJECTIVE: The Trauma Model of dissociative identity disorder (DID) posits that DID is etiologically related to chronic neglect and physical and/or sexual abuse in childhood. In contrast, the Fantasy Model posits that DID can be simulated and is mediated by high suggestibility, fantasy proneness, and sociocultural influences. To date, these two models have not been jointly tested in individuals with DID in an empirical manner. METHOD: This study included matched groups [patients (n = 33) and controls (n = 32)] that were compared on psychological Trauma and Fantasy measures: diagnosed genuine DID (DID-G, n = 17), DID-simulating healthy controls (DID-S, n = 16), individuals with post-traumatic stress disorder (PTSD, n = 16), and healthy controls (HC, n = 16)...

We investigated the frequency of symptom validity test (SVT) failure and its clinical correlates in a large, heterogeneous sample of hospital outpatients referred for psychological assessment for clinical purposes. We studied patients (N=469), who were regularly referred for assessment to the psychology departments of five hospitals. Background characteristics, including information about incentives, were obtained with a checklist completed by the clinician. As a measure of over-reporting, the Structured Inventory of Malingered Symptomatology (SIMS) was administered to all patients...

This study evaluated the clinical utility of two embedded performance validity tests (PVTs) developed for the Repeatable Battery for the Assessment of Neuropsychological Status: the Effort Index (EI) and the Effort Scale (ES) in mild traumatic brain injury (TBI) patients. Participants were 250 military service members (94.0% male; Age: M = 28.4, SD = 7.6) evaluated following mild TBI on average 7.4 months (SD = 15.6) post-injury. Participants were divided into two groups based on their performance on the Test of Memory Malingering: PVT-Pass, n = 193; PVT-Fail, n = 57...

Spatial span tests (SSTs) such as the Corsi Block Test (CBT) and the SST of the Wechsler Memory Scale are widely used to assess deficits in spatial working memory. We conducted three experiments to evaluate the test-retest reliability and clinical sensitivity of a new computerized spatial span test (C-SST) that incorporates psychophysical methods to improve the precision of spatial span measurement. In Experiment 1, we analyzed C-SST test-retest reliability in 49 participants who underwent three test sessions at weekly intervals...

OBJECTIVE: The detection of malingering in cognitive performance is a challenge in clinical and legal environments. Neuroimaging may provide an objective method for delineation of malingering. METHOD: A heterogeneous with concern of gender and racial-ethnic identity of 22 healthy volunteers completed the Tombaugh Test of Memory Malingering during an fMRI scan. Subjects were either instructed to perform optimally (not feigning) or to perform "as if they had a mild traumatic brain injury with memory impairment" (feigning)...

BACKGROUND: The Test of Memory Malingering (TOMM) is an instrument used to assess purposeful embellishment or fabrication of memory difficulties for personal gain. Although the TOMM can be use in non-English speaking cultures, it has not been validated in Spanish-speaking Central and South American contexts. OBJECTIVE: To generate normative data on TOMM across 7 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate...

BACKGROUND: Healthcare professionals are concerned that athletes have the capability to intentionally underperform on baseline computerized neurocognitive assessments in an effort to expedite their return to the field of play following a concussion. The purpose of this study was to determine if the use of overlapping validity measures will provide better sensitivity for detecting malingering athletes on a baseline computerized neurocognitive assessment. METHODS: Twenty male, collegiate rugby players (mean age 23±4 years) participated in this study...

BACKGROUND: Youth have been assumed historically to be less capable of deception than adults, even though acts of deception in childhood are not uncommon. Relatively little attention has focused on how frequently they feign or exaggerate during healthcare evaluations. PURPOSE: The current article reviews the literature relevant to using validity tests in children and adolescents, as well as provides a case example of a young adolescent providing noncredible effort and exaggerated symptomatology during neuropsychological evaluation after a mild traumatic brain injury...

INTRODUCTION: Validity of neuropsychological assessment depends, inter alia, on the cooperation of the examinee, requiring separate assessment. Stand-alone tests devised for detecting negative response bias (NRB) are exposed to potential threats to their validity. In this study, an algorithm was developed for assessing NRB within a standardized, computerized neuropsychological battery (NeuroTrax), making it difficult to detect and circumvent. METHOD: Data were collected from the archived medical records of 75 outpatients with mild to moderate head injury, all in litigation...
