Abstract
Most studies of feigned mental disorders represent broad-based investigations of grossly exaggerated if not outright fabricated clinical presentations. In contradistinction, the current study was sharply circumscribed on “intensification of impairment” (IOI) malingering. With its laser focus on feigned impairment only, could any detection strategy for feigned mental disorders prove effective? To address this question, the study sought to validate the Trauma and Disability Scale for Impairment (TDSI) by applying a within-subject simulation design. A sample of 97 trauma-exposed inpatients completed the TDSI first under standard instructions followed by a simulation condition. Their objective was to successfully meet claims for a total disability motivated by insurance benefits. Promising results indicated that the TDSI identified most of the genuine condition but fell far short for the feigning condition. Future directions are discussed in an effort to develop a more effective TDSI for the assessment of IOI malingering.
