Self-concept correlates of the personality disorders

This study investigated the extent to which the DSM personality disorder dimensions are associated with discrete patterns of self-concept. Participants were 366 men and women who were receiving mental health services and who completed the Wisconsin Personality Disorders Inventory to assess the personality disorders and Benjamin's INTREX questionnaire to describe their "typical" self-concepts. Although there was some overlap between categories, most were associated with fairly distinct patterns of self-concept. The disorders also clustered together in meaningful ways along the major axes of Benjamin's interpersonal model of the self-concept.
