The present review focused on the personality profiles of patients with eating disorders. Studies using the Structured Clinical Interview for DSM-III-R Personality Disorder showed high rates of diagnostic co-occurrence between eating disorders and personality disorders. The most commonly observed were histrionic, obsessive-compulsive, avoidant, dependent and borderline personality disorders. Studies using the Cloninger's personality theory suggested that high Harm Avoidance might be relevant to the pathology of anorexia nervosa and high Novelty Seeking and Harm Avoidance to bulimia nervosa. Moreover, high Self-Directedness was suggested to be associated with favorable outcome in bulimia nervosa. The assessment of personality in a cross-sectional study, however, might be influenced by the various states of the illness. Therefore, a sophisticated longitudinal study will be required to advance this area of research.
