초록

본 연구에서는 폭식행동의 하위 요소 중 하나인 섭식통제 상실(loss of control eating)에 초점을 맞추어 이와 관련된 정서적 요인들과의 관계를 탐색하였다. 연구Ⅰ에서 폭식행동을 구성하는 핵심적인 하위 요인 중 하나인 섭식통제 상실을 측정하는 척도(Eating Loss of Control Scale, ELOCS)를 한국어로 번안하고 타당화하였다. 연구 1에서는 116명의 대학생으로부터 수집된 자료를 토대로 탐색적 요인분석을 실시하여 요인구조를 파악하였으며, 또 다른 128명의 학생들을 대상으로부터 얻은 자료는 확인적 요인분석을 실시하여 ELOCS의 최종 요인구조 및 구성 문항을 결정하였다. 그 결과, 일부 문항이 모형의 적합도를 저해하는 것으로 나타나 문항 제거를 통해 모형을 개선하였다. 섭식통제 상실 척도는 기존의 식사장애 검사와 유의미한 정적 상관을 나타냈으며, 폭식행동과 밀접한 관련이 있는 자기통제, 우울, 조절곤란과도 유의미한 상관을 나타내어 타당도가 양호한 것으로 확인되었다. 연구Ⅱ에서는 부정 정서조급성이 섭식통제 상실에 미치는 영향에 정서인식 명확성이 조절효과를 나타내는지를 확인하였다. 이를 위해 227명의 대학생을 대상으로 수집한 자료를 분석하였다. 위계적 회귀분석 결과, 부정 정서조급성은 성별의 효과를 통제한 후에도 섭식통제 상실을 통계적으로 유의미하게 예측하였다. 또한 부정 정서조급성과섭식통제 상실의 관계에서 정서인식 명확성의 조절효과가 유의미한 것으로 확인되었다. 본 연구에서는 ELOCS가 섭식통제 상실을 측정하는 타당하고 신뢰로운 도구임을 확인하였다. 또한 섭식에 대한 통제 상실을 보이는 사람들은 부정적인 정서를 경험할 때 즉각적인 행동으로 반응하는 경향성이 있는 것으로 나타났다. 또한, 특히 자신과 다른 사람들의 정서를 인식하고 설명하는 능력은 충동적인 기질이 미치는영향을 조절하는 효과를 보여 섭식통제 상실의 보호요인으로 간주할 수 있다고 보았다.

Abstract

The purpose of the present study is to investigate the role of emotional clarity on the relationship between negative urgency and the loss of control eating. In study I, the Eating Loss of Control Scale (ELOCS) was first translated into Korean, and then 116 undergraduate students answered it. To assess the factor structure, exploratory factor analysis was conducted. Thereafter, a confirmatory factor analysis was performed on another set of data from 128 undergraduate students. As a result, the original factor structure was tested by CFA, obtaining a poor fit. An additional model was tested, after deleting the items with bad adjustments, obtaining the best fit. The ELOCS demonstrated a good convergent validity and was significantly correlated with eating pathology, emotion dysregulation, poor self-control, and depression. In study II, the role of emotional clarity was investigated to the hypothesis that emotional clarity has a moderating effect on the relationship between negative urgency and loss of control eating. There were 227 undergraduate students who completed self-report measures. The results of hierarchical analysis showed that after controlling for sex, negative urgency predicted the loss of control eating. When emotional clarity was low, a higher level of negative urgency was associated with a greater loss of control eating. Conversely, when emotional clarity was high, the effect of negative urgency on the loss of control eating was not significant. Such results suggest that the ability to understand and explain themselves as well as the emotions of others can potentially buffer the aggravation of impulsive traits.
