Abstract

Objectives: Previous studies have reported an association between circadian preference and personality. Defense mechanism is unconscious ego process which deals with an individual's anxiety and is closely associated with one's personality. Our aim is to investigate the association between defense mechanism and circadian preference in medical students. Methods: One hundred forty eight medical students (70 males, 78 females), aged 22 to 30, answered the Beck Depression Inventory-II, Morningness-eveningness Questionnaire, and Korean version of Defense Style Questinnaire. Results: Consumption (beta=-0.262, p=0.001) and being a male (beta=0.175, p=0.031) were significant positive predictors of eveningness, while sublimation (beta=0.185, p=0.023) was a significant negative predictor of eveningness. Conclusion: Our study showed a relationship between specific defense mechanisms (i.e., consumption and sublimation) and eveningness in medical students, but it did not address whether the relationship is a causal one.

목 적 : 방어기제는 성격의 영향을 받으며, 방어기제로부터 파생된 행동들을 관찰함으로써 추정 및 측정이 가능하다. 현재까지 방어기제와 일주기 선호 사이의 관계에 대해서는 밝혀진 바가 없었다. 본 연구에서는 일 의학전문대학원 학생들을 대상으로 방어기제와 일주기 선호 사이의 관계를 알아보고자 했다. 방 법 : 일 의학전문대학원 학생 148명을 대상으로 자가설문조사를 시행하였다. 아침형-저녁형 질문지, Beck 우울 척도-2, 한국판 방어유형질문지를 이용하였다. 결 과 : 저녁형과 아침 중간형은 공상, 수동 공격, 소비, 승화, 억제의 방어기제들에서 유의한 차이를 보였다(p<0.05). 다중회귀분석에서 소비가 높을 수록(beta=-0.262, p= 0.001), 승화가 적을 수록(beta=0.185, p=0.023), 여자보다는 남자(beta=0.175, p=0.031)가 저녁형을 유의하게 예측하였다. 결 론 : 본 연구에서는 일 의학전문대학원 학생들에서 소비와 승화의 방어기제가 일주기 선호와 관계된다는 것이 밝혀졌다. 그러나 단면 연구로부터의 결과이므로 둘 사이의 인과 관계에 대해서는 알 수가 없다. 환경 요인을 조정하여 일주기 선호가 바뀔 때 방어기제의 변화가 동반되는지에 대한 후속 연구가 가능할 것이다.
