Abstract

Abstract Objective In neuropsychological assessments, it is critical to evaluate examinee performance validity. Reliable Digit Span (RDS) and the Rey-15 Item Test (FIT) are performance validity tests (PVTs) used to assess the accuracy of results during neuropsychological assessment (NA; Lichtenstein et al., 2017). While many studies have examined adult populations, few examined children to determine the base rate level of PVT failure even in a healthy population. The present study assessed RDS and FIT as PVTs in youth athletes, with valid performance operationalized by Test of Memory Malingering (TOMM) performance. Method Youth athletes (n = 109, 79% male, Mage = 11.9) completed a NA including RDS (cutoff <7), TOMM Trial 2 (cutoff <50), and FIT (cutoff <26) during baseline evaluation for sport participation. A stringent TOMM cutoff was used to improve sensitivity (Schroeder et al., 2012). Receiver operator characteristic (ROC) curve analysis determined whether RDS or FIT performance accurately categorized participants’ validity test performance, based upon TOMM Pass/Fail. Results Both RDS and FIT produced minimal accuracy in categorizing participants performance on TOMM; areas under the curve ranged from 0.41 to 0.60 and did not significantly differ from chance (0.50). Additionally, there was a lack of agreement across PVTs, as no participant failed all three PVTs. Conclusion RDS and FIT did not adequately predict TOMM performance in healthy youth. These findings illustrate that even in a brief NA, healthy children demonstrated variable performance across validity measures, with low consistency across three commonly used PVTs. Findings highlight the importance of clinical judgment in evaluating discrepant PVT performance in children.
