A Development and Validation of the Korean Version of the Yale Food Addiction Scale 2.0


This study was conducted to validate the Yale Food Addiction Scale 2.0 (YFAS 2.0) developed by Gearhardt, Corbin and Brownell (2016) for the measurement of food addiction. For this purpose, 435 adults were recruited from internet cafes, researchers' personal SNS, one university in Daegu and one university in Kyungbuk. The ROC curve was used to adjust the thresholds for each item of the Yale food addiction scale 2.0 to fit the domestic situation. The exploratory factor analysis and the confirmatory factor analysis were conducted to ensure the appropriateness of the factor structure, and the validity and reliability respectively. As a result, first of all, the threshold was changed in 16 of the 35 items. Second, as with the original scale, the single factor structure for 11 symptoms was extracted and the internal consistency was found to be appropriate. As a result of confirmatory factor analysis, it was shown that they had better fit in single factor. Yale food addiction scale 2.0 showed a positive correlation with the Binge Eating Scale (BES) and the general food craving-trait scale (G-FCQ-T). However, unlike previous studies, sub-factors of Three Factor Eating Questionnaire (TFEQ) showed negative correlation with dietary restriction and BMI. Overall, the validated validity, cross validity, and convergent validity of the Yale Food Addiction Scale 2.0 were significant. Finally, the implications and limitations of the study were discussed based on the results of this study.
