초록

본 연구는 건강음식집착증의 선별 도구인 뒤셀도르프 건강음식집착척도(DOS)를 국내 실정에 맞게 타당화하기 위해 시행되었다. 원저자의 동의를 얻어 한국어로 번안한 DOS를 만성질환이나 특정 음식 알레르기로 식단조절을 하고 있지 않은 20-40대 성인 535명에게 실시하고 탐색적 요인분석(n=300)과 확인적 요인분석(n=235)을 실시하였다. 그 결과 ‘건강음식 섭취로 인한 일상의 문제’와 ‘건강음식 섭취에 대한 관심’이 하위요인으로 도출되었고, 2요인 모델에 대한 적합도가 양호하였다. 또한 유사 개념을 측정하는 척도인 역기능적 섭식태도 검사(EAT-26), 강박증상 질문 척도(OCI-R), 질병태도 척도(IAS)와의 상관분석을 통해 수렴 및 변별 타당도를 검증하였다. K-DOS의 전체 문항 내적일치도 및 하위척도의 내적일치도, 반분신뢰도 지수가 양호하여 신뢰도가 확보되었다. 마지막으로 본 연구의 의의와 한계점을 알아보고 추후 연구를 제안하였다.

Abstract

In this study, the Düsseldorf Orthorexia Scale(DOS), a tool for screening orthorexia nervosa, was validated according to the domestic situation. A questionnaire was administered to 535 adults who were in their 20s and 40s and were not currently dieting due to chronic diseases or specific food allergies. The scale was translated into Korean with the consent of the author, and then, an exploratory factor analysis (n=300) and a confirmatory factor analysis (n=235) were performed to examine the factor structure and model fit. As a result of the factor analysis, two sub-factors of ‘daily life problems caused by healthy nutrition preoccupation’ and ‘concern of healthy nutrition' were derived, and the fit of the two-factor model was good. In addition, convergence and discriminatory validity were verified through correlation analysis using the dysfunctional Eating Attitude Test(EAT-26), the Obsessive Compulsive Inventory(OCI-R), and the illness attitude test(IAS), which are measures that assess the related construct. Reliability was ensured as the internal consistency of all items in K-DOS and the internal consistency of subscales as well as split-half reliability were good. Finally, the significance and limitations of this study were investigated, and further studies were suggested.
