Objective: Self-report measures are commonly employed in military healthcare environments to assess service members who sustained mild Traumatic Brain Injuries (mTBI). However, such instruments rarely include validity scales and are susceptible to over-reporting. This study evaluated the test operating characteristics of the mBIAS and the Neurobehavioral Symptom Inventory Validity-10 scale in reference to well validated stand-alone performance validity tests (PVT). Method: Subjects included 339 Active Duty Service Members with a reported history of mTBI, separated into two groups based on Word Memory Test (WMT) or Medical Symptom Validity Test (MSVT) performance (PVT-fail n = 85; PVT-pass n = 254). Sensitivity, specificity, and predictive power values were calculated across the range of mBIAS and NSI Validity-10 scores to determine the optimal cut-off to detect PVT failure. Results: For the mBIAS, a cut score of ≥10 was considered optimal, which resulted in low sensitivity (.11), high specificity (.98), and moderate positive and...
