B - 143 A Comparison of Structured Inventory of Malingered Symptomology (SIMS) Performance to Multiple Validity Measures in a Criminal Forensic Sample.

This article examines the performance of the Structured Inventory of Malingered Symptomatology (SIMS) compared to multiple validity measures in a criminal forensic sample undergoing neuropsychological evaluations. Analyzing data from 119 cases, the study found that 36% of individuals failed the SIMS total score yet passed other validity tests, resulting in a 64% overall concordance rate between SIMS and other measures such as the MMPI-2-RF, WAIS-IV Reliable Digit Span, and the Word Memory Test. The SIMS affective (AF) subscale showed better alignment with other validity measures than the low intelligence (LI) subscale, which performed near chance levels. The findings suggest that SIMS results do not strongly correlate with performance validity tests (PVTs) or symptom validity tests (SVTs) focused on response consistency, indicating classification overlap and potential limitations in generalizability due to the high failure rate of PVT/SVTs in this forensic sample.
