성격에 관한 호르몬적 접근 및 5요인 모형과의 관련성 = Hormonal Approach on Personality and Its Relation to Five-factor Model

국문 초록 (Abstract)

본 연구는 한국인의 성격특성에 관해 조사, 연구하는 것을 목적으로 한다. 본 연구에서는, Helen Fisher와 그녀의 동료들(2010)이 개발한 신경화학적 설문지, FRI-NQ(Fisher-Rich-Island neurochemical questionnaire) 척도를 한국어로 번역하였다. 번역한 FRI-NQ와 한국어판 NEO-FFI를 402명의 대학생과 일반인들을 상대로 측정하여 결과를 분석, 비교하였다. 결과는 다음과 같다. 첫째, NEO-FFI 분석 결과 신경증적 성향과 외향성에 있어 뚜렷하게 유의미한 성차가 발견되었는데, 신경증적 성향에 있어서는 여성이 남성보다, 외향성에 있어서는 남성이 여성보다 유의미하게 높은 것을 나타났다. 둘째, FRI-NQ의 네 가지 척도들 즉, 도파민, 세로토닌, 테스토스테론, 에스트로겐 척도의 평균값을 측정하였고, 각 척도의 성차별, 전공자별 평균치에 있어 유의미한 차이를 드러내었다. 셋째, NEO-FFI와 FRI-NQ의 상관분석 결과, 도파민 척도는 외향성 및 개방성과 유의미한 정적 상관관계를 나타냈다. 세로토닌 척도는 성실성과 매우 높은 정적 상관관계를, 개방성과는 부적 상관관계를 나타냈다.

The purpose of this study is to investigate personality traits of Korean people. In the present study, FRI-NQ(Fisher-Rich-Island Neurochemical Questionnaire) was translated into Korean, originally developed by Helen Fisher and her colleagues in 2010. The subjects were 402 Korean adults, who were tested with Korean versions of FRI-NQ and NEO-FFI. The results are the following. First, there were significant gender differences in the scales of Neuroticism and Extraversion of NEO-FFI, in which females were more neurotic than males whereas males were more extravert than females. Secondly, the four subscales(Dopamine, Serotonin, Testosterone, and Estrogen) of FRI-NQ showed significant means differences across gender and college majors. Thirdly, the results of correlational studies between NEO-FFI and FRI-NQ revealed that the Dopamine scale was positively correlated with Extraversion and Openness scales of NEO-FFI. Serotonin scale was very highly and positively correlated with Conscientiousness scale, but negatively correlated with Openness scale.
