Abstract
This article on malingering-related topics in forensic and disability-related assessments (FDRA) examines malingering “detection” systems, such as the malingered neurocognitive dysfunction (MND) system, and its revision. The article examines, as well, the malingered pain-related disability (MPRD) detection system. We conclude that none of these systems reach the required standards for reliability and validity in toto. The article moves on to discuss the Erdodi Index (EI) System, which can vary in the number of indicators and cognitive domains (e.g., attention, memory, processing speed). The article ends by presenting a list of 25 factors that could influence responses on performance validity tests (PVTs) and symptom validity tests (SVTs) across multiple areas. Among others, these factors relate to the examinee, testing, and extraneous factors, such as litigation distress. Workers in the field are cautioned to vet and to use carefully any malingering-related detection system and in gravitating to malingering as a stock interpretation of failed PVTs/SVTs.
