Over-Reporting of Somatic and Psychiatric PTSD Symptoms Among People Who Experienced Motor Vehicle Accidents and Did Not Seek Psychiatric Help in a Primary Care Setting.

The results suggest that in primary care settings, PE-MVA with PTSD who do not seek psychiatric help, over-report psychiatric and somatic symptoms. In a personal injury setting the F scale of the MMPI-2 showed less sensitivity to exaggerated somatic symptoms than the FBS scale. Bias scales of PE-MVA with PTSD are major contributors to the elevation of the MMPI-2 scores but not the CAPS-2 score.
