Assessment malingering

Michael E Keesler, Kirstie McClung, Tawny Meredith-Duliba, Kelli Williams, Thomas Swirsky-Sacchetti
OBJECTIVE: Evaluating assessment validity is expected in neuropsychological evaluation, particularly in cases with identified secondary gain, where malingering or somatization may be present. Assessed with standalone measures and embedded indices, all within the testing portion of the examination, research on validity of self-report in the clinical interview is limited. Based on experience with litigation-involved examinees recovering from mild traumatic brain injury (mTBI), it was hypothesized that inconsistently reported date of injury (DOI) and/or loss of consciousness (LOC) might predict invalid performance on neurocognitive testing...

With the population aging, the legal and mental health systems need to be prepared for cases that involve older adults beyond the customary matters of guardianship and competency. Assessing older adults with the current tests raises concerns because these measures may not be adequately normed for this age group. Malingering, factitious disorders, and somatoform disorders are discussed due to health-related issues of normal aging. These topics complicate the assessment procedure and need consideration because they may affect the claimant's performance or symptom presentation...

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)...

BACKGROUND: Receiving real-time information on tissue properties while performing biopsy procedures has the potential of improving biopsy accuracy. The study goal was to test the ability of a miniature flexible Radio-Frequency (RF) sensor (Dune Medical Devices), designed to be mounted on the surface of surgical tools, in measuring and mapping the various breast tissue types and abnormalities in terms of electrical properties. METHODS: Between January and October 2012, 102 patients undergoing lumpectomy, open-biopsy or mastectomy, in 3 medical centers, were enrolled in this study...

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)...

OBJECTIVE: Fibromyalgia syndrome (FM) patients demonstrate deficits in tests of attention, executive functioning and verbal memory. We assessed the role of effort in the cognitive impairment in FM patients, alongside common symptoms of pain, fatigue and depression. METHOD: 50 FM patients underwent a computerized cognitive assessment battery including memory, executive function, attention and information processing speed (NeuroTrax Corp.). Age and education standardized scores were computed...

OBJECTIVE: This research examined cutoff scores for MMPI-2 and MMPI-2-RF validity scales specifically developed to assess non-credible reporting of cognitive and/or somatic symptoms. The validity scales examined included the Response Bias Scale (RBS), the Symptom Validity Scales (FBS, FBS-r), Infrequent Somatic Responses scale (Fs), and the Henry-Heilbronner Indexes (HHI, HHI-r). METHOD: Cutoffs were developed by comparing a psychometrically defined non-malingering group with three psychometrically defined malingering groups (probable, probable to definite, and definite malingering) and a group that combined all malingering groups...

Malingering by proxy (MAL-BP) is a form of maltreatment that involves a caregiver who fabricates or induces signs or symptoms in a child, dependent adult, or pet in pursuit of external, tangible incentives. Rarely studied, MAL-BP has an unknown prevalence, and is a challenging diagnosis for healthcare professionals. Therefore, a comprehensive computer literature search and review was conducted. The review uncovered a total of sixteen case reports of MAL-BP (eleven human, five veterinary). The motive for malingering was financial in all human cases and medication-seeking in all veterinary cases...

The Structured Inventory of Malingered Symptomatology (SIMS) is a standalone symptom validity test (SVT) designed as a screening measure to detect a variety of exaggerated psychological symptoms. A number of studies have explored the accuracy of the SIMS in litigious and clinical populations, yet few have examined the validity of the SIMS in detecting feigned symptoms of postconcussional disorder (PCD) and posttraumatic stress disorder (PTSD). The present study examined the sensitivity of the SIMS in detecting undergraduate simulators (N = 78) feigning symptoms of PCD, PTSD, and the comorbid presentation of both PCD and PTSD symptomatologies...

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...

The current study expands on past research examining the comparative capacity of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al., 2001) and MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011) overreporting validity scales to detect suspected malingering, as assessed by the Miller Forensic Assessment of Symptoms Test (M-FAST; Miller, 2001), in a sample of public insurance disability claimants (N = 742) who were considered to have potential incentives to malinger. Results provide support for the capacity of both the MMPI-2 and the MMPI-2-RF overreporting validity scales to predict suspected malingering of psychopathology...

Tests of design fluency (DF) assess a participant's ability to generate geometric patterns and are thought to measure executive functions involving the non-dominant frontal lobe. Here, we describe the properties of a rapidly administered computerized design-fluency (C-DF) test that measures response times, and is automatically scored. In Experiment 1, we found that the number of unique patterns produced over 90 s by 180 control participants (ages 18 to 82 years) correlated with age, education, and daily computer-use...

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...

INTRODUCTION: The prenatal diagnosis of fetal craniosynostosis is challenging, especially in single-suture cases. When sutures are obliterated, sound waves fail to penetrate the cortical bone, creating an evident acoustic shadow on the underlying brain. The objective of this study was to evaluate the yield of the 'brain shadowing sign' (BSS) as a novel sonographic marker for craniosynostosis. SUBJECTS AND METHODS: Patients with an antenatal diagnosis of fetal craniosynostosis (cases) and healthy controls paired for gestational age were enrolled in this retrospective case-control study...

Between 1914 and 1918, war strain appeared under a number of guises and affected, to varying extents, the majority of French soldiers. The most frequent form of war strain was war psychoneurosis, but war strain also induced more paroxystic disorders, such as acute episodes of terror, self-mutilation, induced illnesses and even suicide. Fear was the constant companion of soldiers of the Great War: soldiers were either able to tame it or overwhelmed by an uncontrollable fear. Nonetheless, over the course of the war, some aspects of fear were recognised as syndromes...
