Note. NSI = Neurobehavioral Symptom Inventory; mBIAS = Mild Brain Injury Atypical Symptoms; DoD = Department of Defense; VA = Veterans Affairs; TBI = traumatic brain injury; PCL-M = PTSD Checklist-Military; MMPI = Minnesota Multiphasic Personality Inventory; RF = Restructured Form; PAI = Personality Assessment Inventory.
Cutoffs are shown as score (sensitivity/specificity). Shaded cells are non-author recommended cutoff but reflecting highest sensitivity at specificity ≥ .90. For Bodapati (2019) the 2 scores are for possible versus probable exaggeration. For Ashendorf (2020) other than mBIAS, scores presented are for predicting invalid on any MMPI-2-RF validity scale. All samples were clinical contexts (not forensic).
