The symptoms of ADHD are highly subjective, and there is ample empirical evidence that demonstrates the ease with which impairments in attention can be feigned on many commonly used subjective and objective measures of attention. We examined the combination of two assessment measures, NV-MSVT and IVA+, to screen for performance validity and ADHD symptoms in college students. Results indicated that the NV-MSVT was effective in differentiating between students with potential high impairment, such as ADHD, and possible malingerers...

OBJECTIVES: The Medical Symptom Validity Test (MSVT) offers a profile analysis for performance validity, but individuals performing with suboptimal performance validity are frequently misidentified by current profile rules. The aim of this study was to develop and validate a new profile analysis for the MSVT. METHOD: This study utilized 2 phases to investigate current profile analyses and construct a new analysis. Phase I compared graduate students and adult volunteers asked to simulate dementia to individuals with dementia in long-term care facilities...

The purpose of the current study was to compare three potential profiles of the Medical Symptom Validity Test (MSVT; Pass, Genuine Memory Impairment Profile [GMIP], and Fail) on other freestanding and embedded performance validity tests (PVTs). Notably, a quantitatively computed version of the GMIP was utilized in this investigation. Data obtained from veterans referred for a neuropsychological evaluation in a metropolitan Veteran Affairs medical center were included (N = 494). Individuals age 65 and older were not included to exclude individuals with dementia from this investigation...

BACKGROUND: Preseason baseline testing using computerized neurocognitive tests (CNTs) is increasingly performed on athletes. Adequate effort is critical to establish valid estimates of ability, but many users do not evaluate performance validity, and the conditions that affect validity are not well understood across the available CNTs. PURPOSE: To examine the rates and predictors of invalid baseline performance for 3 popular CNTs: Automated Neuropsychological Assessment Metrics (ANAM), Axon Sports, and Immediate Post-Concussion and Cognitive Testing (ImPACT)...

Performance validity tests (PVTs) are not widely used beyond medico-legal contexts in the UK. A UK survey suggests clinicians have reservations about their accuracy in clinical settings. This study sought to explore the validity of PVTs in an acute adult neuropsychology setting and to establish a potential "false positive" (FP) base rate. Failures on the Medical Symptom Validity Test (MSVT) in a consecutive clinical series of 405 patients were evaluated systematically and allocated to groups depending on clinical context...

Inadequate effort during neuropsychological examination results in inaccurate representations of an individual's true abilities and difficulties. As such, performance validity tests (PVTs) are strongly recommended as standard practice during adult-based evaluations. One concern with using PVTs with children is that failure reflects immature cognitive ability rather than non-credible effort. The current study examined performance on the Medical Symptom Validity Test (MSVT) in two large pediatric clinical samples with strikingly different neuropsychological profiles: (1) mild traumatic brain injury (mTBI; n = 510) and (2) fetal alcohol spectrum disorder (FASD; n = 120)...

OBJECTIVE: This study examined the psychiatric and neuropsychological profiles of people with psychogenic nonepileptic seizures (PNES). METHODS: Twenty-people who had been diagnosed with psychogenic nonepileptic seizures (PNES), but not epilepsy, were recruited into this study. A healthy control group was also recruited and was matched for age and gender. All participants underwent structured psychiatric assessment and psychometric assessment. Neuropsychological assessment was carried out using the Cambridge Neuropsychological Test Battery (CANTAB) after participants passed the Medical Symptom Validity Test (MSVT) of effort...

Previous studies of performance on the Word Memory Test (WMT; Green, 2003 ; Green & Astner, 1995 ) in adults with very low intelligence have provided conflicting evidence. Most studies suggest that a Full-Scale IQ (FSIQ) less than 70 cannot explain failure on the WMT, but Shandera et al. ( 2010 ) suggest that many adults with mental retardation (MR) cannot pass the WMT. If so, we would expect adults with such low intelligence to fail the WMT at a high rate, even if they were motivated to perform well. In the current study, parents with an FSIQ of 70 or less, who were seeking custody of their children, rarely failed the WMT or the Medical Symptom Validity Test (MSVT; Green, 2004 )...

If we wish to conclude that failure on a performance validity test (PVT) is a false positive for poor effort, we must have evidence that the person is truly incapable of passing the test because of cognitive impairment. We must show that they have a diagnostic condition that is sufficient to account fully for failure on that test. The purpose of the current study was to evaluate the performance of children with a primary diagnosis of intellectual disability (ID) on the Word Memory Test (WMT), the Medical Symptom Validity Test (MSVT), and the Nonverbal Medical Symptom Validity Test (Green, 2003 , 2004 , 2008b ; Green & Astner, 1995 )...

Validity measures derived from the Test of Memory Malingering Trial 1 (TOMM1) and errors across the first 10 items of TOMM1 (TOMMe10) may be further enhanced by combining these scores with "embedded" behavioral responses while patients complete these measures. In a sample of nondemented veterans (n = 151), five possible behavioral responses observed during completion of the first 10 items of the TOMM were combined with TOMM1 and TOMMe10 to assess any increased sensitivity in predicting Medical Symptom Validity Test (MSVT) performance...

Since the early 2000s concern has increased that college students might feign ADHD in pursuit of academic accommodations and stimulant medication. In response, several studies have validated tests for use in differentiating feigned from genuine ADHD. Although results have generally been positive, relatively few publications have addressed the possible impact of the presence of psychological disorders comorbid with ADHD. Because ADHD is thought to have accompanying conditions at rates of 50% and higher, it is important to determine if the additional psychological disorders might compromise the accuracy of feigning detection measures...

BACKGROUND: The symptomatology after mild traumatic brain injury (mTBI) is complex as symptoms are subjective and nonspecific. It is important to differentiate symptoms as neurologically based or caused by noninjury factors. Symptom exaggeration has been found to influence postinjury presentation, and objective validity tests are used to help differentiate these cases. This study examines how concussed patients seen for initial medical workup may present with noncredible effort during follow-up neuropsychological examination and identifies physical findings during evaluation that best predict noncredible performance...

OBJECTIVE: Assessment of response validity is an integral part of forensic neuropsychological evaluations. The utility of performance validity measures (PVMs) in patients with potentially impaired cognitive functioning is less studied. The purpose of the current study was to compare the three potential profiles of the Medical Symptom Validity Test (MSVT; Pass, Genuine Memory Impairment Profile [GMIP], and Fail) on other freestanding and embedded PVMs. METHOD: Patients referred for a neuropsychological evaluation in a metropolitan Veteran Affairs medical center were included (N = 638)...

The current study sought to evaluate the sensitivity of the Word Memory Test, Medical Symptom Validity Test, and the Nonverbal Medical Symptom Validity Test (NV-MSVT) in a group of 50 well-educated individuals asked to simulate dementia. With use of the Genuine Memory Impairment Profile as operationalized by the Advanced Interpretation Program, sensitivities for single measures and the measures in combination ranged from 54% to 98% in the detection of suboptimal effort. Overall, the NV-MSVT appeared the most sensitive to feigned memory impairment in this sample...

A number of performance validity tests (PVTs) are used to assess memory complaints associated with traumatic brain injury (TBI); however, few studies examine the concordance and predictive accuracy of multiple PVTs, specifically in the context of combined models in known-group designs. The present study compared five widely used PVTs: the Test of Memory Malingering (TOMM), Medical Symptom Validity Test (MSVT), Reliable Digit Span (RDS), Word Choice Test (WCT), and California Verbal Learning Test - Forced Choice (CVLT-FC)...

This study examined the performance of 198 Veteran research participants deployed during Operation Enduring Freedom, Operation Iraqi Freedom, and/or Operation New Dawn (OEF/OIF/OND) on four measures of performance validity: the Medical Symptom Validity Test (MSVT), California Verbal Learning Test: Forced Choice Recognition (FCR), Reliable Digit Span (RDS), and TOVA Symptom Exaggeration Index (SEI). Failure on these performance validity tests (PVTs) ranged from 4% to 9%. The overall base rate of poor performance validity, as measured by failure of the MSVT in conjunction with an embedded PVT (FCR, RDS, SEI), was 5...

BACKGROUND: A minority of pediatric patients who have mild traumatic brain injury (mTBI) report persistent postconcussive symptoms. In adults, failure on validity tests, which help to detect exaggerated or feigned problems, is associated with symptom complaints. No pediatric studies have examined the relationship between validity test performance and symptom report. We hypothesized that children failing a validity test would report significantly more postconcussive symptoms than those passing...

In adult populations, research on methodologies to identify noncredible performance and exaggerated symptoms during neuropsychological evaluations has grown exponentially in the past two decades. Far less work has focused on methods appropriate for children. Although several recent studies have used stand-alone performance validity tests with younger populations, a near absence of pediatric work has investigated other indices to identify response bias. The present study examined the relationship between the validity scales from the self-report Behavior Assessment System for Children, Second Edition (BASC-2) and performance on the Medical Symptom Validity Test (MSVT), a stand-alone performance validity test...
