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.
目的
本研究旨在检验中文版修正耶鲁食物成瘾量表 2.0（C-mYFAS 2.0）的心理测量特性，并分析中国大学生食物成瘾的流行率及其与韧性和社会支持的关系。
方法
共有 1132 名中国大学生完成了 C-mYFAS 2.0、BES、EAT-26、PHQ-9、GAD-7、TFEQ-18、CD-RISC-10 和 PSSS。采用验证性因子分析评估 C-mYFAS 2.0 的因子结构，并评估其心理测量特性。在子样本（n=62）中评估重测信度。采用 Spearman 相关和逻辑回归分析韧性、社会支持与食物成瘾的关系。
结果
根据 C-mYFAS 2.0，食物成瘾的患病率为 6.2%。验证性因子分析表明存在单因子结构（比较拟合指数=0.961）。C-mYFAS 2.0 具有良好的重测信度和内部一致性（Kuder-Richardson 的α=0.824）。与暴食、饮食障碍症状、抑郁症状、广泛性焦虑症状、无法控制的进食、情绪性进食和 BMI 的相关性（p<0.001）表明具有良好的聚合效度。与认知控制无关联反映了适当的发散效度。最后，暴食与 C-mYFAS 2.0、抑郁症状和饮食障碍症状显著相关（p<0.001），证实了增量效度。此外，我们的研究发现，韧性和社会支持较差与食物成瘾有关（p<0.001）。
结论
C-mYFAS 2.0 是一种简短但可靠和有效的中国大学生食物成瘾筛查工具。此外，我们发现韧性和社会支持与食物成瘾呈负相关。
