Abstract

We documented effort stability during neuropsychological (NP) testing examining failure rates on three Performance Validity Tests (PVTs). 65 student athletes, ages 8-21, were evaluated in an outpatient practice, following sports-related concussion over three sessions within 18 months of injury (mean=6 months). 7.7% of student athletes failed PVTs at all three test sessions, 7.7% failed PVTs at two test sessions, and 12.3% failed PVTs at one session; 28% of this sample was sub-optimally engaged for at least one test session, producing invalid neuropsychological data at the time of testing and 72% produced valid neuropsychological data across the comprehensive evaluation.
