A - 183 Novel Performance Validity Indicators for Frequently Used Memory Tests Using Infrequent Patterns of Memory Performance.

The article focuses on developing novel performance validity indicators (PVTs) for commonly used memory tests, specifically the Hopkins Verbal Learning Test–Revised (HVLT-R) and Brief Visuospatial Memory Test–Revised (BVMT-R), to improve assessment accuracy in neuropsychological evaluations of patients with Major Neurocognitive Disorder (MND). Using infrequent patterns of memory performance (IPOP) identified in a primarily amnestic dementia population, the study analyzed data from 50 adult outpatients and found that traditional embedded PVTs showed high failure rates (16–58%), suggesting potential false positives. In contrast, the new IPOP-based scaled scores indicated fewer failures (under 15%), indicating these novel indicators may better differentiate valid from invalid memory performance in clinical populations. This approach aims to reduce misclassification in performance validity assessments among individuals with cognitive impairments.
