Abstract
Neuropsychological evaluation is a valuable tool for characterizing individual neurocognitive profiles in a range of congenital and acquired brain conditions. The usefulness of neuropsychological testing relies on accurate data which can only be obtained from reliable and credible performance. Inaccurate test data can lead to an underestimate of a child’s true abilities, false diagnoses, and a misallocation of community resources and services. Performance validity tests (PVTs) are stand-alone or embedded measures that assist psychologists in determining if an individual’s performance is valid. Despite a growing understanding in the importance of consistently using PVTs in pediatric neuropsychological evaluation over the last 15 years, research and clinical use continues to lag behind relative to adult neuropsychological practice. In particular, there is a dearth of evidence investigating the use of PVTs among children and adolescents with reading difficulties and with specific learning disorder in reading/dyslexia. It is important to empirically validate the use of PVTs in this population to avoid false determinations of noncredible performance. It may be that children and adolescents with reading difficulties perform worse on tests that require them to draw on related cognitive vulnerabilities. Thus, this study aims to analyze and report failure rates of the Memory Validity Profile (MVP), the automatized sequences task, an embedded digit span measure, and the Hillside Rating Scale. This study also aims to compare these measures to one another and determine if reading difficulties or other variables are correlated with PVT failure. We hope that this study will contribute to the paucity of literature on the topic and help clinicians feel more confident selecting PVTs for clinical use with children and adolescents with reading difficulties.
