![]() The relationship between emotional symptoms and cognitive test performance diminished substantially when validity test performance was controlled, and validity test performance had a substantially larger impact than emotional symptoms on cognitive test performance. ![]() PVTs and SVTs had an additive effect on cognitive test performance for uncomplicated mTBI, but less so for more severe TBI. Atypical PVT and SVT performance were associated with poorer cognitive test performance and higher emotional symptom report, irrespective of TBI severity. Data analyses included independent t-tests, one-way ANOVAs, correlation analyses, and hierarchical multiple regression.Ī total of 370 participants were included. ![]() All participants completed a cognitive test battery, the Personality Assessment Inventory (including symptom validity tests SVTs), and multiple performance validity tests (PVTs). Participants underwent neuropsychological assessment between January 2012 and June 2021 in the context of compensation-seeking claims related to a TBI. ![]() This study examined the relative contribution of performance and symptom validity in litigating adults with traumatic brain injury (TBI), as a function of TBI severity, and examined the relationship between self-reported emotional symptoms and cognitive tests scores while controlling for validity test performance.
