기분 안정기에 있는 양극성 장애 I형 환자를 정신병적 증 상의 유무에 따라 두 군으로 분류하고 기질성격 특성을 대 조군과 비교함으로써 양극성 장애 환자의 특징적인 인격 구 조를 알아보았다. 정신병적 증상이 동반되었던 환자군은 대 조군과 비교하여 높은 HA와 ST를 보였고, 정신병적 증상 이 없었던 환자군보다 높은 HA를 보였다. 따라서 본 연구 는 정신병적 증상의 유무에 따라 양극성 장애가 다른 유형 으로 구분될 가능성을 보여주었다. 또한 이런 기질성격 특성 은 정신병적 장애와 유사하며, 정신병적 경향과의 연관성을 시사한다.

Objectives：The aim of this study was to exam whether personality, i.e. temperament and character, has an association with a previous presence of psychotic features in euthymic bipolar I disorder. Methods：We recruited 25 psychotic patients with bipolar I disorder, 23 non-psychotic bipolar I patients and 48 normal controls. All subjects were asked to perform Temperament and Character Inventory (TCI). Euthymic state was defined in bipolar patients by scores of below 10 on the Hamilton Depression Rating Scale (HDRS) and on the Young Manic Rating Scale (YMRS). Results：Psychotic bipolar patients, compared to normal controls, showed higher harm avoidance (HA) and self-transcendence (ST). In addition, HA in psychotic bipolar patients was higher than that in non-psychotic bipolar patients. However, no significant differences on TCI were demonstrated between non-psychotic patients and normal controls. Conclusion：There are significant discrepancies in personality between psychotic and non-psychotic bipolar patients on HA and ST. These findings are consistent with the hypothesis of a continuum between bipolar disorder with psychotic features and psychotic disorders. (J Korean Neuropsychiatr Assoc 2006;45(5):427-431
