Prior research shows that Digit Span is a useful embedded measure of malingering. However, the Wechsler Adult Intelligence Scale-IV (Wechsler, 2008) altered Digit Span in meaningful ways, necessitating another look at Digit Span as an embedded measure of malingering. Using a simulated malingerer design, we examined the predictive accuracy of existing Digit Span validity indices and explored whe...

BACKGROUND Detection of feigned neurocognitive deficits is a challenge for neuropsychological assessment. We conducted two studies to examine whether memory malingering is characterized by an elevated proportion of false negatives during yes/no recognition testing and whether this could be a useful measure for assessment. METHODS Study 1 examined 51 participants claiming compensation due to m...

The nosological conception of Ganser syndrome (GS) has evolved as the hysterical etiopathogenesis has been examined against psychosis, malingering, factitious disorders and/or organic lesions. Few articles and little scientific research and theory are available supporting the complicated diagnosis of GS. The similarities and differences between GS and factitious disorders and malingering are ex...

The DSM criteria for identifying malingering are reviewed and found to be flawed on both conceptual and practical grounds. Alternative models for diagnosing feigned psychiatric, physical, and neuropsychological symptoms are presented. A number of useful features of these systems are highlighted for potential contributions to modified DSM criteria. It is recommended that the present DSM text on ...

This study examined the ability of four measures of suboptimal performance to correctly classify four groups of subjects (normal controls, uncoached malingering, coached malingering, and head injured). Only the Portland Digit Recognition Test-Computerized (PDRT-C) identified simulating malingerers with greater than chance accuracy while minimizing false positives. Coached subjects were better a...

Studies on MMPI and MMPI-2 malingering indexes often sacrifice generalizability in an attempt to control internal validity. This study improves external validity while still maintaining internal validity by providing graduate student participants with a realistic context for malingering on the MMPI-2 (n=94) and MMPI (n=30). Contextual parameters include a realistic life predicament, psychologic...
