 Objective : Personality is an important factor which influences clinical manifestation and outcome in eating disorder patients. Although some studies have assessed personality traits of eating disorder patients by using temperament and character inventory (TCI : Cloninger et al.), little is known about the relationship of personality to clinical manifestation. This study evaluated dimensional personality and temperamental characteristics in patients with eating disorders in Japan and examined their association with the clinical manifestation.

 Method : TCI was administered to 51 patients diagnosed with eating disorder according to DSM-IV (13 AN-restricting type, 15 AN-binge eating type, 23 BN) and 47 normal controls. Eating disorder inventory (EDI) and clinical symptoms of all the patients were investigated.

 Results and Conclusions : Eating disorder patients exhibited significantly lower self directedness (SD) scores compared to healthy controls. SD scores are related to introceptive awareness, ineffectiveness and interpersonal distrust on the EDI scale, and existence of impulsive behaviors. Past history of major depressive disorder and psychiatric family history was related to the cooperativeness (C) dimensions. We concluded that self-determination and the ability of an individual to control, regulate and adapt behavior to fit the situation in accordance with individually chosen goals and values play an important role on the psychopathology of eating disorders. But these results may reflect the depressive symptoms or mood instabilities in patients. Further research concerning treatment response is needed.
