정서억제가 개인의 신체증상에 어떤 영향을 미치는지 검증하고 이 때에 자기구성개념의 조절효과를 확인하는 것이 이 연구의 목적이다. 성인 한국인(N=201, 여: 148, 남: 53)을 대상으로 실시한 온라인 설문을 통해 정서억제, 신체증상, 자기구성개념을 측정하였다. 그 결과, 정서억제는 신체증상에 유의한 영향을 미치는 것으로 검증되었는데 높은 정서억제 경향은 신체증상에 부정적인 영향을 주는 것으로 보고되었다. 자기구성개념의 조절효과를 검증한 결과 정서억제와 신체증상과의 관계에서 독립적 자기구성개념의 경우에만 유의한 조절효과가 검증되었다. 단술기울기 검증(slope analysis)을 통해 상호작용의 양상을 살펴 본 결과, 독립적 자기구성개념이 평균에서 1 표준편차 이상 높은 경우에만 조절효과가 유의했다. 이는 독립적 자기구성개념이 높은 사람들의 경우에만, 정서억제를 할수록 더 많은 신체증상을 보고하는 것을 의미한다. 이 연구 결과는 정서억제에 대해 일관되지 않던 기존의 국내 연구결과와 달리, 한국인도 정서를 억제할수록 신체적 건강에 부정적인 영향을 미침을 검증하였고, 특히 이 때 개인이 두드러지게 보이는 자기구성개념의 종류나 그 패턴에 따라 정서억제가 신체적 건강에 미치는 영향력이 달라질 수 있음을 검증하였다는 의의가 있다.
A majority of studies conducted in Western cultures suggest that emotion suppression has a negative effect on physical and psychological health. However, recent studies indicate that such negative effects may differ depending on one’s self-construal. The purpose of this study was to examine the effects of emotion suppression on physical and depressive symptoms and to determine if self-construal moderates this effect in a community adult sample in Korea. Results demonstrated that emotion suppression significantly affected participants’ physical as well as depressive symptoms. Independent self-construal showed a significant moderating effect only on the relationship between emotion suppression and physical symptoms. Whereas previous studies conducted with Koreans failed to examine the significant effect of emotion suppression on individuals’ adjustment, the results of this study demonstrated the effects of emotion suppression in Koreans. The results highlight the role of independent self-construal in explaining the effect of emotion suppression on physical health.
