Abstract

Performance validity tests (PVT) should be used when assessing youth with mild traumatic brain injury (MTBI). The goal of this study was to derive a new cutscore for determining invalid performance on the Memory Validity Profile (MVP) in youth with MTBI. Children and adolescents (N = 92; mean age =14.8 years, SD = 2.3, range =8-18) on average six months (SD = 3.6) post-MTBI were administered the MVP as part of their assessment. Two validated PVTs [Test of Memory Malingering (TOMM) and Medical Symptom Validity Test (MSVT)] were administered and used to group the sample into valid (n = 73, neither TOMM/MSVT failed) and invalid (n = 19, both TOMM/MSVT failed). New cutscores for the MVP to determine invalid performance in this sample were established using failure on both TOMM/MSVT as the criterion. MVP performance correlated significantly with failure on TOMM/MSVT. Youth with invalid performance had significantly lower MVP total scores and area under the curve was.80, suggesting good separation of groups. A cutscore of 31 or less on the MVP provided sensitivity of 63% for detecting invalid performance with 93% specificity. This study yields a promising new cutscore for the MVP that has good sensitivity and strong specificity for detecting invalid performance in youth with MTBI.
