기분안정기 1형 양극성장애 환자의 정서조절 전략 특성 : 조현병과의 비교

Abstract

Objectives : Models of bipolar disorder have stressed the importance of troubled emotion regulation. We assessed emotion regulation strategies and difficulties of emotion regulation in euthymic patients with bipolar disorder (BD) compared to healthy controls (HC) and schizophrenia patients (SZ). Methods : Forty seven euthymic bipolar patients, 28 schizophrenia patients and 59 healthy controls were asked to complete emotion regulation questionnaire (ERQ) and Korean version of Difficulties in Emotion Regulation Scale (K-DERS). Results : We found BD made similar use in cognitive reappraisal of ERQ with HC, greater than SZ (p=0.006). ; HC also made greater use than SZ (p=0.010). It showed BD had no difference in suppression with both HC and SZ, despite HC had lesser use than SZ (p=0.023). BD with history of psychotic features made no difference in cognitive reappraisal compared to SZ while BD with no history of psychotic features made greater use than SZ (p=0.033). Conclusion : This finding suggests patients with euthymic bipolar disorder have no distinct feature of emotion regulation strategies compared to healthy controls, whereas schizophrenia patients use maladaptive strategies. We propose the similarity in emotional regulation strategies between psychotic bipolar disorder and schizophrenia associated with analogous aspects of cognitive impairment can be targeted for new treatments.
