The utility of the structured interview of reported symptoms in a sample of individuals with intellectual disabilities.

The challenges of accurate forensic assessment are aggravated when evaluatees have intellectual disabilities. Few studies have addressed the efficacy of forensic assessment in samples diagnosed with an intellectual disability, and those that have typically focus on measures of cognitive effort rather than on feigned psychiatric symptoms. This study focuses on the applicability of the original and revised versions of the Structured Interview of Reported Symptoms (SIRS) in a sample of participants with genuine intellectual disabilities.

Do tests of malingering concur? Concordance among malingering measures.

Malingering test accuracy is increasingly a major issue in psychology and law. Integrating results across measures might offset limitations of a single test, but the practical benefits of using several tests depend on the extent to which they misclassify the same individuals. Data from 66 evaluatees were used to assess the degree of overlap and consistency of classification among several commonly used malingering instruments.
