This paper sought to demonstrate that diagnosable malingering does occur in Electrical Injury (EI) and examine the relationship of malingering to potential indicators of the presence and severity of neurological injury. Eleven consecutive EI patients seen for neuropsychological evaluation were presented. Over half the patients met the Slick et al. (1999) criteria for at least Probable MND. Most...

This study examine the relationship of biographical and case history data thought to be associated with malingering to known indices of malingering based on MMPI and sentence-completion test data. Subjects were 65 patients who had undergone formal psychiatric evaluations in connection with ongoing litigation over injury-related disability. Biographical/case history data were reduced to six fact...

Despite their theoretical appeal, Bayesian methods for the assessment of poor effort and malingering are still rarely used in neuropsychological research and clinical diagnosis. In this article, we outline a novel and easy-to-use Bayesian latent group analysis of malingering whose goal is to identify participants displaying poor effort when tested. Our Bayesian approach also quantifies the conf...

The purpose of this study is to further previous research that has shown that common neuropsychological tests can do "double duty" as test of motivation/malingering. Using a large clinical sample of 796 participants, it was found that the nine neuropsychological tests (when used together) were able to correctly identify litigant and nonlitigating groups. Failure on any two of the malingering te...

The effects of incentive and preparation on performance and classification accuracy of standard and malingering-specific tests were investigated in a simulation study using a 2 (no incentive vs. a $20 incentive) x 2 (immediate vs. delayed preparation) factorial design. Eighty undergraduate students and 15 individuals with traumatic brain injury were administered standard (viz., Digit Span and V...

Previous research has demonstrated the ability of the Cognitive Behavioral Driver's Inventory (CBDI) to detect neuropsychological malingering [Arch. Clin. Neuropsychol. 12 (5) (1997) 491.], however, the present study tests if the CBDI can discern malingerers when they are "coached" on how brain-damaged patients actually perform on neuropsychological tests. Ninety-eight college student participa...

The potential for malingering must always be considered among patients presenting with pain. When malingering is identified, care may be discontinued. This case report describes a patient who feigned sickle cell crisis, a painful condition, in the presence of other identifiable and potentially painful medical illnesses.

INTRODUCTION The Forced-choice Graphics Memory Test (FGMT) is a newly developed measure to assess feigned cognitive impairment. This study investigated the ability and reliability of FGMT for identification of malingering in patients with traumatic brain injury (TBI). METHODS The FGMT was administered to 40 healthy volunteers instructed to respond validly (Healthy Control, H-C), 40 healthy vo...

To empirically investigate the usefulness and validity of clinical presentation and recent history variables in the detection of malingered psychiatric disorder, 30 criminal defendants involved in forensic evaluations, who had a documented history of psychiatric hospitalization preceding their arrest on the instant offense (low risk of malingering group) and 30 defendants who complained of psyc...
