섭식장애 위험군 선별을 위한 한국판 SCOFF 척도의 타당화 연구: 20대 여자 대학생을 중심으로

초록

The SCOFF questionnaire, developed by Morgan et al. (1999), is a brief screening tool widely used to identify individuals at high risk for eating disorders. Despite its international adoption, previous studies in Korea reported low reliability, limiting its applicability. This study aimed to validate the Korean version of the SCOFF questionnaire. A total of 300 female university students participated in exploratory factor analysis (EFA) and a two-parameter logistic multidimensional item response theory (2PL-MIRT) analysis. The results supported a two-factor structure (purging behavior and Body Image and Eating Cognitions) consistent with the Spanish and Iranian versions. The IRT analysis indicated that the questionnaire effectively identified individuals at risk for eating disorder symptoms, and the original cutoff score of 2 points accurately classified high-risk cases. Confirmatory factor analysis (CFA) with 120 additional participants confirmed the model’s fit. The scale were significantly related with eating attitudes, weight concerns, anxiety, depression, and self-esteem, establishing its validity. These findings support the applicability of the Korean SCOFF questionnaire for eating disorder screening and highlight directions for future research.
