기분안정기 1형 양극성장애 환자의 심상 특성 및 정서 조절

Abstract

Objectives : We investigated characteristics of mental imagery and its relation to emotion regulation in euthymic patients with bipolar I disorder using self-report measurements. Methods : Fifty euthymic bipolar I patients and 50 healthy control subjects participated. We applied Korean version of Difficulties in Emotion Regulation Scale (KDERS) to assess emotion regulation difficulties. Spontaneous Use of Imagery Scale (SUIS) and Vividness of Visual Imagery Questionnaire (VVIQ) were conducted to assess tendency towards general use and vividness of imagery, respectively. Results : Patients with bipolar I disorder showed significantly lower scores in VVIQ (t=-2.043, p=0.044), but not in SUIS, than healthy participants. Bipolar patients also showed significantly higher scores in KDERS than healthy controls (t=2.091, p=0.039). However, there was no association of the ratings of VVIQ or SUIS with K-DERS, and also no significant relations between characteristics of mental imagery and mood symptom scores. Conclusion : These findings suggest that bipolar patients maintain the high level of vividness in mental imagery despite euthymic mood. However, we couldn’t find any relationships between emotion regulation and mental imagery. More delicate measures, such as specific imagery or emotion regulation tasks, will be needed to demonstrate the relationship of two aspects.
