Differences in the Personality Profile of Medication‐Overuse Headache Sufferers and Drug Addict Patients: A Comparative Study Using MMPI‐2

Abstract

The data obtained show that MOH and SA do not share common personality characteristics linked to dependence. Although further studies are needed to understand if such a difference is related to instrumental characteristics or to yet undiscovered psychobiological characteristics of MOH patients; however, we hypothesize that the detected difference may rely on the fact that drug dependence in the 2 groups is promoted by entirely different needs: pleasure seeking in the SA group, pain avoidance in the MOH group.
