The Yale Food Addiction Scale 2.0 (YFAS) assesses addiction-like eating of palatable foods based on the 11 diagnostic criteria for substance use disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study was the first to investigate the factor structure, psychometric properties, and clinical significance of the YFAS 2.0 in individuals with binge-eating disorder (BED) symptomatology. Data were analysed from 220 community-based participants who met criteria for "probable BED" based on self-report symptom frequency. Classification of food addiction (FA) was met by 42.3% of the sample. The YFAS 2.0 exhibited a unidimensional structure, adequate internal consistency, and convergent and incremental validity. YFAS 2.0 scores contributed the largest percentage of unique variance in psychological distress and impairment over other BED features (overvaluation of weight and shape, binge eating, BMI), highlighting the clinical significance of the FA construct in BED. Support for the validity and reliability of the YFAS 2.0 in individuals with BED-like symptoms was found. Findings also suggest that the presence of FA may represent a more disturbed group of BED characterised by greater general and eating disorder-specific psychopathology. Our findings overall highlight the potential need to screen and assess addictive-like eating behaviours during interventions for BED.
耶鲁食物成瘾量表 2.0（YFAS）根据《精神障碍诊断与统计手册（第五版）》（DSM-5）中物质使用障碍的 11 项诊断标准，评估类似成瘾的美味食物的食用情况。本研究首次调查了暴食障碍（BED）症状个体中 YFAS 2.0 的因子结构、心理测量特性和临床意义。数据分析来自 220 名符合“可能 BED”标准的基于自我报告症状频率的社区参与者。42.3%的样本符合食物成瘾（FA）分类。YFAS 2.0 表现出单一维度结构、足够的内部一致性以及收敛和增量有效性。YFAS 2.0 评分在心理困扰和功能障碍方面对其他 BED 特征（体重和体型的过度重视、暴饮暴食、BMI）的独特方差贡献最大，突出了 FA 结构在 BED 中的临床意义。在 BED 样症状个体中，YFAS 2.0 的有效性和可靠性得到了支持。研究结果还表明，FA 的存在可能代表了 BED 中一个更紊乱的群体，其特点是更普遍和饮食障碍特定的精神病理学。总的来说，我们的研究结果强调了在 BED 干预过程中筛查和评估类似成瘾的进食行为的潜在必要性。
