Abstract

This study investigated the differential effects of childhood trauma, especially neglect, emotional abuse, and physical abuse on stress perception in relation to the ToM (theory of mind), among one-hundred and fifty five college students. For this purpose, self-reported childhood neglect, emotional abuse, physical abuse, and stress levels during the previous week were measured. Social cognition was measured using a ToM questionnaire which asked respondents to guess the intentions of the person in each vignette by providing additional hints. In order to examine the predicting role of childhood trauma and mediating role of ToM, two distinct structural models assuming full (Model 1) and partial (Model 2) mediational effects were compared using structural equation modeling. The partial mediational model was supported and the main results were as follows. First, childhood neglect indirectly predicted stress perception through the effect of the ToM. Second, childhood emotional abuse directly predicted stress perception. Third, childhood physical abuse had no distinct effect on stress perception. Finally, the limitations of this study and the implications for future studies are discussed.

아동기 외상은 발달 과정에서 심리적 그리고 생물학적 문제를 초래하고, 이 문제들이 사회인지 발달과 공변하여 이후 스트레스 대처에 장애물로 지속적으로 작용할 수 있다고 가정하였다. 이에 아동기 외상, 구체적으로 방임, 신체학대 및 정서학대의 경험이 성인이 된 시점에서 지각하는 스트레스 수준에 영향을 미치는지, 그리고 그 과정에서 마음이론이 매개역할을 하는지 알아보았다. 이를 위해 대학생 155명을 대상으로 아동기 외상 및 지난 일주일 간 지각한 스트레스 수준을 측정하는 자기보고식 척도를 실시하였다. 사회인지 능력의 하나인 마음이론을 측정하는 질문을 실시하고 필요한 경우 면담자가 힌트를 제공하는 구조화된 방식으로 측정하였다. 최종 151명을 대상으로 실시한 공변량구조분석을 통하여 마음이론의 완전매개 효과를 가정한 모형(모형 1)과 부분매개 효과를 가정한 모형(모형 2)의 간명성과 부합도를 비교하였다. 완전 매개효과 모형을 보면, 마음이론이 스트레스 지각에 영향을 미치는 경로가 유의하였고, 아동기 방임이 마음이론에 영향을 미치는 경로가 유의하였다. 아동기 정서학대가 마음이론에 영향을 미치는 경로는 경향성만 나타내었고, 아동기 신체학대가 마음이론에 영향을 미치는 경로는 유의하지 않았다, 부분 매개 효과 모형을 보면, 아동기에 경험한 방임은 마음이론에 영향을 미치고, 이는 다시 스트레스 지각에 영향을 미쳤다. 아동기에 경험한 정서학대는 성인기의 스트레스 지각에 직접적으로 영향을 미쳤다. 상관분석 및 완전, 부분 매개효과 모형에서 모두 아동기의 세 가지 유형의 외상 경험은 유의한 상호상관관계를 보였다. 모형의 간명성과 부합도를 비교한 결과에서는 최종적으로 부분 매개효과 모형이 채택되었다. 마지막으로 본 연구의 의의와 제한점, 후속연구를 위한 제언을 논의하였다.
