METHOD: A total of 114 post-9/11 veterans were evaluated utilizing the Neurobehavioral Symptom Inventory (NSI) Validity-10, four embedded PVTs, mTBI screening, and a diagnostic interview for PTSD. RESULTS: While we found concordance between embedded PVTs and the NSI Validity-10 at select cutoffs (i.e., ≥13, ≥19), symptom and performance validity indicators were clinically dissociable in that only SVT significantly predicted diagnosed PTSD and screened mTBI. CONCLUSIONS: Dissociation between symptom and performance validity may be clinically useful when interpreting neuropsychological evaluation findings in post-9/11 veterans with a history of mTBI or PTSD.
