Malingering in the Psychiatric Emergency Department: Prevalence, Predictors, and Outcomes.

Psychiatr Serv 2018 Dec 10:appips201800140. Epub 2018 Dec 10.

Department of Psychiatry, Yale University School of Medicine, New Haven, Connecticut (Rumschik); Department of Psychiatry, Mount Sinai Beth Israel, New York, and Program in Ethics Education in Psychiatry, Icahn School of Medicine at Mount Sinai, New York (Appel).

Objective:: Malingering is commonly encountered in the psychiatric emergency department, yet little is known about its prevalence, objectives, or effect on patient management. This study analyzed characteristics of malingering and patient disposition in a 24/7-staffed comprehensive psychiatric emergency program (CPEP) and created predictive models to understand malingering and its effect on physician decision making.

Methods:: Attending psychiatrists completed questionnaires after comprehensive assessments of 405 patients presenting to the CPEP during the 1-month study, recording suspicion of malingering, symptoms malingered, associated secondary gains, demographic characteristics, and initial disposition decision.

Novel ImPACT validity indices in collegiate student-athletes with and without histories of ADHD or academic difficulties.

Clin Neuropsychol 2018 Dec 5:1-12. Epub 2018 Dec 5.

a Department of Psychological Sciences , Kent State University , Kent , OH , USA.

Objective: Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) assesses neurocognitive functioning in sports-related concussion. Previous work demonstrates ImPACT's validity indices detect poor effort at disproportionately higher rates in athletes with histories of attention deficit hyperactivity disorder (ADHD) or academic difficulties. The present study examines whether previously suggested 'dormant' validity indices, Word Memory Correct Distractors (WMCD), and Design Memory Correct Distractors (DMCD), reduce disproportionate invalidity in collegiate athletes with such histories.

Electrophysiology in diagnosis and management of neuropathic pain.

Rev Neurol (Paris) 2018 Oct 25. Epub 2018 Oct 25.

Inserm U1028, CNRS, UMR5292, central integration of pain (NeuroPain) Lab - Lyon neuroscience research center, université Claude Bernard, 69677 Bron, France; Department of Clinical Neurophysiology, Neurological Institute, Faculty of Medicine, Graduate School of Medical Science, Kyushu University, Fukuoka, 812-8582, Japan.

Electrophysiological techniques demonstrate abnormalities in somatosensory transmission, hence providing objective evidence of 'somatosensory lesion or disease' which is crucial to the diagnosis of neuropathic pain (NP). Since most instances of NP result from damage to thermo-nociceptive pathways (thin fibres and spino-thalamo-cortical systems), specific activation of these is critical to ensure diagnostic accuracy. This is currently achieved using laser pulses or contact heat stimuli, and in a near future probably also with contact cold and intra-epidermal low-intensity currents. Read More

Malingering and factitious disorder.

Pract Neurol 2018 Nov 13. Epub 2018 Nov 13.

Nuffield Orthopaedic Hospital, Oxford Centre for Enablement, Oxford, UK.

Although exaggeration or amplification of symptoms is common in all illness, deliberate deception is rare. In settings associated with litigation/disability evaluation, the rate of malingering may be as high as 30%, but its frequency in clinical practice is not known. We describe the main characteristics of deliberate deception (factitious disorders and malingering) and ways that neurologists might detect symptom exaggeration. Read More

[Classification accuracy of the symptom validity tests Word Memory Test and the German version of the Structured Inventory of Malingered Symptomatology].

Nervenarzt 2018 Oct 29. Epub 2018 Oct 29.

Zentrum für Psychiatrie Südwürttemberg, Klinik für Psychiatrie und Psychotherapie I der Universität Ulm, Ravensburg-Weissenau, Deutschland.

Background: The symptom validity tests Word Memory Test (WMT) and "Strukturierter Fragebogen Simulierter Symptome" (SFSS, German version of the Structured Inventory of Malingered Symptomatology, SIMS) are used in psychiatric expert reviews in the context of social benefit proceedings to elucidate the validity of a patient's symptom presentation and to unveil possible malingering. Many of the studies on the WMT and the SFSS estimated the sensitivity and specificity of the tests by using student populations or healthy volunteers. The objective of the present study was to investigate the accuracy of the WMT and the SFSS in a clinical sample and if their combined use leads to better classification results. Read More

Complex regional pain syndrome and functional neurological disorders: time for reconciliation.

J Neurol Neurosurg Psychiatry 2018 Oct 24. Epub 2018 Oct 24.

Centre for Clinical Brain Sciences, Western General Hospital, NHS Lothian and University of Edinburgh, Edinburgh, UK

There have been many articles highlighting differences and similarities between complex regional pain syndrome (CRPS) and functional neurological disorders (FND) but until now the discussions have often been adversarial with an erroneous focus on malingering and a view of FND as 'all in the mind'. However, understanding of the nature, frequency and treatment of FND has changed dramatically in the last 10-15 years. FND is no longer assumed to be only the result of 'conversion' of psychological conflict but is understood as a complex interplay between physiological stimulus, expectation, learning and attention mediated through a Bayesian framework, with biopsychosocial predisposing, triggering and perpetuating inputs.

Detecting over-reporting of symptoms: the French version of the self-report symptom inventory.

Clin Neuropsychol 2018 Jan-Dec;32(sup1):164-181. Epub 2018 Oct 15.

c Institut de Recherche en Sciences Psychologiques (IPSY), Centre de Neuroscience Système et Cognition (NeuroCS) , Université Catholique de Louvain , Louvain-la-Neuve , Belgium.

Objective: Symptom exaggeration and malingering are core issues in forensic and clinical evaluation. Generally, experts use two main types of instruments to assess the credibility of symptoms: performance validity tests that aim to detect underperformance and self-report validity tests that appraise over-reporting of symptoms. However, while many tools can be used to assess underperformance, far fewer instruments are available to evaluate over-reporting of symptoms. Read More

1 South Texas Veterans Health Care System, San Antonio, TX, USA.

To supplement memory-based Performance Validity Tests (PVTs) in identifying noncredible performance, we examined the validity of the two most commonly used nonmemory-based PVTs-Dot Counting Test (DCT) and Wechsler Adult Intelligence Scale-Fourth edition (WAIS-IV) Reliable Digit Span (RDS)-as well as two alternative WAIS-IV Digit Span (DS) subtest PVTs. Examinees completed DCT, WAIS-IV DS, and the following criterion PVTs: Test of Memory Malingering, Word Memory Test, and Word Choice Test. Validity groups were determined by passing 3 (valid; n = 69) or failing ⩾2 (noncredible; n = 30) criterion PVTs. Read More

Differentiating poor validity from probable impairment on the medical symptom validity test: a cross-validation study.

Int J Neurosci 2018 Nov 28:1-8. Epub 2018 Nov 28.

e Henry Ford Allegiance , Jackson , MI , USA.

Aims: In neuropsychological evaluations, it is often difficult to ascertain whether poor performance on measures of validity is due to poor effort or malingering, or whether there is genuine cognitive impairment. Dunham and Denney created an algorithm to assess this question using the Medical Symptom Validity Test (MSVT). We assessed the ability of their algorithm to detect poor validity versus probable impairment, and concordance of failure on the MSVT with other freestanding tests of performance validity. Read More

Differentiating factitious psychological presentations from malingering: Implications for forensic practice.

Behav Sci Law 2018 Sep 17. Epub 2018 Sep 17.

University of North Texas, Denton, TX, USA.

Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code.

Detecting clinical and simulated dissociative identity disorder with the Test of Memory Malingering.

Psychol Trauma 2018 Sep 13. Epub 2018 Sep 13.

Department of Psychology.

Objective: Few studies have assessed malingering in individuals with complex trauma and dissociation. This is concerning because these individuals' severe and ranging symptoms are associated with elevations on some, but not all, validity scales that detect symptom exaggeration. Dissociative individuals may experience dissociative amnesia, yet no study to date has examined how to distinguish clinical from malingered amnesia with dissociative samples. Read More

Smell & Taste Center, University of Pennsylvania, Philadelphia, PA 19104, USA.

Although hundreds of thousands of patients seek medical help annually for disorders of taste and smell, relatively few medical practitioners quantitatively test their patients' chemosensory function, taking their complaints at face value. This is clearly not the approach paid to patients complaining of visual, hearing, or balance problems. Accurate chemosensory testing is essential to establish the nature, degree, and veracity of a patient's complaint, as well as to aid in counseling and in monitoring the effectiveness of treatment strategies and decisions.

The Identification of Torsades de Pointes via CEEG: A Case Report on a Patient with Physiologically Provoked Nonepileptic Events.

Neurodiagn J 2018 ;58(2):91-106

a Department of Clinical Neurophysiology , Medical University of South Carolina , Charleston , South Carolina.

Continuous electroencephalography (CEEG) is chiefly performed at The Medical University of South Carolina (MUSC) for identifying seizures, including its refined use within the epilepsy monitoring unit (EMU) as a differentiator between epileptic and psychogenic etiologies. CEEG also provides critical data that carry implications outside the bounds of both epilepsy and psychogenic events, such as the characterization of unorthodox clinical phenomena that are of physiological (though nonepileptic) origins. Although nonepileptic events (NEEs) are primarily linked with psychogenic phenomena (conversion disorder, malingering) that can mimic epileptic activity, they, like seizures, have diverse semiologies and etiologies.

Approach to the Patient with Disproportionate Pain.

Bull Hosp Jt Dis (2013) 2018 Jun;76(2):123-132

Faced with a patient who presents with unexplained disproportionate pain, a surgeon may be tempted to diagnose a low pain threshold, malingering, poor coping, anxiety, or other emotional condition. However, a variety of conditions must be ruled out before the orthopedist can prescribe watchful waiting. Computed tomography and magnetic resonance imaging can detect occult fractures, acute spinal conditions or vascular occlusions, but early on are inadequate to diagnose a compartment syndrome, necrotizing fasciitis, or reflex sympathetic dystrophy (RSD).
