   Proposal Description:
   This project will examine classification accuracy of cutoffs on                   neuropsychological measures identified in prior research as embedded              performance validity tests (PVTs). For example, the Trail Making Test (TMT) is a widely used measure of attention and processing speed that has raw score cutoffs associated with questionable performance validity. Embedded PVTs on the TMT and many other meausures have primarily been examined in traumatic brain injury populations. It remains important to extend these findings in other clinical areas. Healthy adults and groups with various dementias are populations useful for studying the specificity of previously established PVT     cutoffs. The study will focus on specificity of previously reported cutoffs on embedded PVTs in control, mild cognitive impairment, and dementia participants.    A second aim is to focused on different PVT failure rates by race and ethnicity. The of racial and ethnic influences on neuropsychological test scores extends to PVTs, especially embedded ones since they often use a floor effect cutoff. It is important to understand how race and ethnicity might affect such embedded scores to reduce false positive errors. We will look at PVT failure rates between African American and white participants. Results might also support analyses with other ethnic groups, depending on the number of available cases.
