Word reading performance differed significantly according to PVT failure status, and number of PVTs failed accounted for 7.4% of the variance in word reading performance, even after controlling for education. Furthermore, individuals failing >/=2 PVTs were twice as likely as individuals passing all PVTs (33% vs. 16%) to have abnormally low obtained word reading scores relative to demographically predicted scores when using a normative base rate of 10% to define abnormality. When compared with standardization study clinical groups, those failing >/=2 PVTs were twice as likely as patients with moderate to severe traumatic brain injury and as likely as patients with Alzheimer's dementia to obtain abnormally low TOPF word reading scores. Findings indicate that TOPF word reading based estimates of premorbid functioning should not be interpreted in individuals invalidating cognitive testing.<p> Dementia Assessment Alzheimer's Disease 10.1177/1073191116656796 2022-02-21T22:48:57.408-06:00
