Objective: To develop an MMPI-2-RF reference group for persistently symptomatic patients with mTBI in order to aid interpretation and better evaluate atypical scale elevations.
Method: Using the Q Local MMPI-2-RF Comparison Group Generator (CGG), 200 valid MMPI-2-RF profiles were aggregated for mTBI outpatients with persisting symptoms 2-24 months post injury.
Results: Compared to established MMPI general population norms, individuals with persisting symptoms demonstrated elevations on several scales, primarily in cognitive and somatic domains.
