The Montreal Cognitive Assessment Test (MoCA) as a screening tool for cognitive dysfunction in fibromyalgia.

Clin Exp Rheumatol 2022 Jun 8;40(6):1136-1142. Epub 2022 Jun 8.

Institute of Rheumatology, Tel Aviv Sourasky Medical Centre, Israel.

Objectives: Cognitive dysfunction is one of the criteria for the diagnosis of fibromyalgia (FM) and is typically based on self-report questionnaires such as the Symptom Severity Scale. However, recent studies have shown that there is no correlation between these subjective measures of cognitive dysfunction and more lengthy objective measures of cognitive functioning. This points to the need for a briefer valid evaluation tool for cognitive dysfunction in FM. Read More

The parent-reported ADHD symptom infrequency scale (PRASIS): a parent report measure of ADHD symptom exaggeration.

Child Neuropsychol 2022 May 26:1-21. Epub 2022 May 26.

Department of Psychology, Central Michigan University, Mount Pleasant, MI, USA.

The present article outlines the development of the parent-reported ADHD symptom infrequency scale (PRASIS), a novel stand-alone questionnaire designed to discriminate between parents exaggerating ratings of ADHD symptoms of their child from parents more accurately reporting symptoms. The PRASIS includes an Infrequency scale (INF) to measure infrequently reported symptoms of ADHD and a clinical scale to measure Diagnostic and Statistical Manual of Mental Disorders-5 Edition (DSM-5) defined ADHD symptoms (ADHD Total). An initial list of infrequency and clinical items was revised over the course of three studies, each conducted on a different sample of participants ( = 154,  = 203,  = 167) recruited via CloudResearch and consisting of mothers of children 4-12 years old.

Analysis of malingered psychological symptoms in a clinical sample for early detection in initial interviews.

Eur Arch Psychiatry Clin Neurosci 2022 May 19. Epub 2022 May 19.

Department of Educational Sciences, University of Extremadura, 06006, Badajoz, Spain.

Malingering consists of the production of false physical or psychological symptoms motivated by external incentives that are normally reproduced in pathologies that are not related to organic origin or there are no laboratory tests for their diagnosis, as is the case of mixed anxiety-depressive disorder and fibromyalgia syndrome. The objective of this research consisted of comparing the profile of simulative patients with fibromyalgia and mixed anxiety-depressive disorder to obtain a profile and facilitate its detection in initial interviews. The research was carried out with 78 patients (42 patients with fibromyalgia and 36 patients with mixed anxiety-depressive disorder) who were administered the professional's structured clinical judgment, the Beck Depression Inventory, the State-Trait Anxiety Questionnaire, and the Structured Symptom Simulation Inventory.

Malingering of Psychotic Symptoms in Psychiatric Settings: Theoretical Aspects and Clinical Considerations.

Psychiatry J 2022 21;2022:3884317. Epub 2022 Apr 21.

University of Missouri Kansas City, Department of Psychiatry, Kansas City, MO, USA.

Malingering is the intentional production of false or grossly exaggerated physical or psychological symptoms motivated by external incentives. Although the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) does not list malingering in its diagnostic section and therefore does not identify it as a formal mental disorder, malingering and verified mental illness commonly coexist. Some subtypes of feigning behaviors, such as partial or pure malingering, dissimulation, and false imputation, can be suspected when patients have marked discrepancies between reported stressors and objective findings.

Functional Cognitive Disorder: Differential Diagnosis of Common Clinical Presentations.

Arch Clin Neuropsychol 2022 Apr 28. Epub 2022 Apr 28.

Academic Neurology Unit, University of Sheffield, Sheffield, UK.

Background: Cognitive symptoms in the absence of neurological disease are common. Functional cognitive disorder (FCD) has been conceptualized as a cognitive subtype of functional neurological disorder. Although FCD is understood as different from exaggerated or feigned cognitive complaints, previous accounts have provided little practical advice on how FCD can be separated from factitious or malingered cognitive complaints.

Assessment of Malingering among Servicemembers with a Focused Examination of Explanatory Models.

J Am Acad Psychiatry Law 2022 Apr 27. Epub 2022 Apr 27.

Dr. Rogers is Regents Professor of Psychology, Department of Psychology, University of North Texas, Denton, TX. Ms. Chang and Mr. Pan are Advanced Doctoral Students in Clinical Psychology, University of North Texas, Denton, TX.

Umbrasas briefly mentioned established models of malingering that sought to understand the driving motivations for feigning mental disorders. He used these models as a point of departure to consider the unique experiences and enduring challenges of active and retired servicemembers. For military malingering, he identified acute distress malingering and disability malingering with the former occurring within the first five years and the latter after a military career had been established.

Identifying Feigned ADHD in College Students: Comparing the Multidimensional ADHD Rating Scale to Established Validity Measures.

J Atten Disord 2022 Apr 25:10870547221092095. Epub 2022 Apr 25.

Columbia University, New York, NY, USA.

Objective: There is increased concern for malingering in ADHD evaluations due to presence of incentives such as accommodations and medications. Although several validity tests are available to classify malingering in non-ADHD populations, there is no test with proven effectiveness to detect feigned ADHD. This study investigated the ability of the MARS Symptom Validity Index 4 (MARS SV-index 4) and two published validity tests (the Word Memory Test [WMT] and Clinical Assessment of Attention Deficit-Adult [CAT-A] Infrequency scale) to detect malingered ADHD.

Symptom coaching and symptom validity tests: An analog study using the structured inventory of malingered symptomatology, Self-Report Symptom Inventory, and Inventory of Problems-29.

Appl Neuropsychol Adult 2022 Apr 13:1-13. Epub 2022 Apr 13.

Department of Psychology, University of Turin, Torino, Italy.

In this pilot and exploratory study, we tested the robustness of three self-report symptom validity tests (SVTs) to symptom coaching for depression, with and without additional information available on the Internet. Specifically, we divided our sample ( = 193) so that each subject received either the Structured Inventory of Malingered Symptomatology (;  = 64), the Self-Report Symptom Inventory (;  = 66), or the Inventory of Problems-29 (;  = 63). Within each of the three subgroups, approximately one third of participants were instructed to respond honestly (Genuine Condition, = 21; = 24; = 26) and approximately two-thirds were instructed to feign depression.

An examination of the MMPI-3 validity scales in detecting overreporting of psychological problems.

Psychol Assess 2022 Jun 24;34(6):517-527. Epub 2022 Feb 24.

Department of Psychology.

The recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes a revised set of Validity Scales on which there is currently limited validity and clinical utility evidence for the detection of overreporting. The present study evaluated the MMPI-3 Validity Scales in the identification of such response bias. An analogue simulation design was used in which participants in an overreporting condition (163 undergraduate students) were instructed to feign mental health symptoms when responding to the MMPI-3 in the context of a compensation-seeking claim.

Cry for help as a root cause of poor symptom validity: A critical note.

Appl Neuropsychol Adult 2022 Feb 23:1-6. Epub 2022 Feb 23.

Vivantes Klinikum im Friedrichshain, Berlin, Germany.

When patients fail symptom validity tests (SVTs) and/or performance validity tests (PVTs), their self-reported symptoms and test profiles are unreliable and cannot be taken for granted. There are many well-established causes of poor symptom validity and malingering is only of them. Some authors have proposed that a cry for help may underlie poor symptom validity. Read More
