  • Title: Performance validity test and neuropsychological assessment battery screening module performances in an active-duty sample with a history of concussion.
    Author: Grills CE, Armistead-Jehle P.
    Journal: Appl Neuropsychol Adult; 2016; 23(4):295-301. PubMed ID: 26943837.
    Abstract:
    The current retrospective investigation sought to replicate previous findings demonstrating the significant impact of performance validity test (PVT) performance and evaluation context on neuropsychological testing. We examined differences on performance validity testing between active-duty service members undergoing neurocognitive screening for concussion who were seen in a clinical context and those who were seen in a disability-seeking context, as well as the overall impact of PVT performance on a neurocognitive screening battery. Overall, 38.2% of the sample failed the Word Memory Test (WMT). Of those involved in a disability evaluation, the failure rate was 51.9%, which was significantly higher than the 36.8% failure rate among those evaluated in a clinical context. The effect size of WMT performance on a cognitive screening measure was also large. The current retrospective analysis served to replicate previous work.
