Abstract/Description: Twenty to 30% of defendants undergoing criminal forensic evaluations have been reported to be malingering. Given that the most common type of criminal forensic evaluation is the assessment of competency to stand trial, the assessment of malingering during competency evaluations is very important. Most malingering literature focuses on psychiatric malingering (i.e. feigned psychosis), although in assessment of competency, the larger issue involves feigned deficits in factual or legal knowledge. The relationship between intelligence and performance on malingering tests is also important because individuals with intellectual deficits may be incorrectly identified as malingering on these tests. The current study used a sample of state psychiatric hospital residents who had been adjudicated incompetent to proceed to trial and several groups of students instructed to simulate malingering or incompetence. It was hypothesized that adding an additional administration of the Inventory of Legal Knowledge (ILK) would improve the identification of individuals motivated to feign factual knowledge deficits. The results of this hypothesis were supported in the student simulation sample but not in the hospital sample. Further analyses attempted to identify an optimal cut-score on the ILK due to a recent critique on its psychometric properties and the results of these analyses differed by sample and by the independent criterion variables used to identify individuals malingering. Finally, the current study examined the relationship between intelligence and performance on the ILK and indicated two items on the ILK which were correlated with intelligence. Future directions and implications of this study are discussed.
