초록
본 연구는 자기개념 명확성이 이상 섭식 행동에 미치는 영향과 신체 비교, 신체 불만족의 매개효과를 확인하기 위한 것이다. 선행연구들에 근거하여 자기개념 명확성이 신체 비교와 신체 불만족의 이중 매개를 통해 이상 섭식 행동에 영향을 줄 것이라 가정하였다. 연구참여자는 전국에 있는10~20대 여성 총 386명을 대상으로 실시되었으며 설문업체인 인바이트를 통해 온라인 설문조사가 실시되었다. 측정도구로는 자기개념 명확성(SCCS), 이상 섭식 행동(KEAT-26), 신체 비교(PACS+SACS), 신체 불만족(BSQ)척도가 사용되었다. 분석 방법은 Anderson과 Gerbing(1988)이제안한 방식인 2단계 접근법(Two step approach)에 따라 측정 모형을 검증 후 구조모형을 검증하였고 연구모형과 대안모형을 만들어 χ²검증을 통해 차이를 비교하였다. 마지막으로 자기개념명확성과 이상 섭식 행동의 매개효과를 확인하기 위해 부트스트랩(bootstrapping)절차를 사용하였다. 연구결과는 다음과 같다. 첫째, 낮은 자기개념 명확성과 신체 비교 및 신체 불만족, 이상 섭식행동 모두 유의미한 정적상관을 가짐을 확인하였다. 둘째, 자기개념 명확성과 이상 섭식 행동간에신체 비교와 신체 불만족의 순차적 이중 매개모형이 수집된 자료에 가장 적합한 것으로 나타났다. 이를 고려해 볼 때, 자기개념을 명확히 정의함으로써 타인과의 신체 비교행동을 줄일 수 있고 감소된 신체 비교행동은 자신의 신체에 대한 불만족도를 낮춤으로써 이상 섭식 행동을 줄일 수 있음을 시사한다. 끝으로, 연구 의의와 제안점 등에 대해 논의하였다.
Abstract
The purpose of the study is to examine the influence of self-concept clarity, physical comparison, and body dissatisfaction on disordered eating behaviors. The participants were 386 females aged 10 to 29 years, recruited by online survey. They received questionnaires to measure their self-concept clarity(SCCS), physical comparison(PACS+SACS), body shape(BSQ), and disordered eating behaviors(KEAT-26) scale. Based on previous studies, the researcher constructed one research model and four alternative models to navigate the most suitable explanation for the data, and verified the influence of variables and the significance of the mediating effect. In order to compare the one research model and four alternative models, structural equation modeling(SEM) was used. The SEM revealed that the full dual mediation model fit the data well. The findings suggest that low self-concept clarity might contribute to disordered eating behaviors because it increases women’s vulnerability to physical comparison tendencies and body dissatisfaction. Finally, the implications and limitations of this study and suggestions for future study were addressed.
