Abstract
PURPOSE: This study aimed to examine the psychometric properties of the Chinese version of the modified Yale Food Addiction Scale 2.0 (C-mYFAS 2.0) and to analyze the prevalence of food addiction among Chinese college students and its relationship with resilience and social support. METHODS: A total of 1132 Chinese college students completed the C-mYFAS 2.0, BES, EAT-26, PHQ-9, GAD-7, TFEQ-18, CD-RISC-10, and PSSS. Confirmatory factor analysis was used to evaluate the factor structure of the C-mYFAS 2.0 and psychometric properties were assessed. Test-retest reliability was evaluated in a sub-sample (n = 62). Spearman correlation and logistic regression were used to examine the relationship between resilience, social support, and food addiction. RESULTS: The prevalence of food addiction according to the C-mYFAS 2.0 was 6.2%. Confirmatory factor analyses suggested a single-factor structure (comparative fit index = 0.961). The C-mYFAS 2.0 had good test-retest reliability and internal consistency (Kuder-Richardson's α = 0.824). Good convergent validity was indicated by correlations with binge eating, eating disorder symptoms, depressive symptoms, generalized anxiety symptoms, uncontrolled eating, emotional eating, and BMI (ps < 0.001). Appropriate divergent validity was reflected by no association with cognitive restraint. Finally, binge eating was significantly predicted by C-mYFAS 2.0, depressive symptoms, and eating disorder symptoms (ps < 0.001), confirming incremental validity. In addition, our study found that poorer resilience and social support were related to food addiction (ps < .001). CONCLUSIONS: The C-mYFAS 2.0 is a brief but reliable and valid screening instrument for food addiction among Chinese college students. In addition, we found that resilience and social support were negatively associated with food addiction. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
