Malingering in forensic contexts has garnered increased attention in recent years. As a result, the past two decades have seen the development of more than a half dozen instruments to assess response styles. Although these instruments are gaining unprecedented popularity among forensic practitioners, there is little research on how closely practitioners adhere to the published guidelines for administration or interpretation. This article provides a case study of the use of one popular instrument, the Structured Inventory of Reported Symptoms, in an insanity case. Misinterpretation of the defendant’s scores contributed to the misclassification of malingering, which was used to bolster the government’s case at trial. This case suggests the need for better training and more caution when using instruments to assess response styles in forensic contexts.
