目的评估改良耶鲁食物成瘾量表2.0（mYFAS 2.0）在意大利非临床样本中的维度和心理测量学特性。方法对262名成年人（184名女性）进行了意大利版的mYFAS 2.0，问卷调查测量暴饮暴食的严重程度，焦虑和抑郁症状，情绪失调。结果15例（5.7%）符合mYFAS 2.0食物成瘾诊断标准。贝叶斯验证性因素分析支持mYFAS 2.0的单因素解决方案。mYFAS 2.0内部一致性良好（序数a = 0.91），和收敛效度与暴饮暴食的严重程度焦虑（r = 0.31，p < 0.001）、抑郁（r = 0.35，p <0.001）、情绪调节困难（r = 0.35，p < 0.001）。最后，证实了饮食限制的判别效度（Gamma = 0.11; p = 0.52）和预测暴食严重程度超过情绪失调和精神病理学的增量效度（B = 0.52; t = 11.11; p < 0.001）。结论意大利mYFAS 2.0具有令人满意的心理测量学特性，可以作为一个简短的工具，用于评估成瘾性饮食行为时，时间限制，防止使用的原始版本。证据等级V，横断面描述性研究。
Purpose To assess the dimensionality and psychometric properties of the modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) in an Italian non-clinical sample. Methods 262 adults (184 women) were administered the Italian versions of the mYFAS 2.0, and questionnaires measuring binge eating severity, anxiety and depression symptoms, and emotional dysregulation. Results 15 individuals (5.7%) met the criteria for a diagnosis of food addiction according to the mYFAS 2.0. Bayesian confirmatory factor analysis supported a single-factor solution for the mYFAS 2.0. The mYFAS 2.0 had good internal consistency (Ordinal a = 0.91), and convergent validity with binge eating severity (r = 0.67, p < 0.001), both anxiety (r = 0.31, p < 0.001) and depressive (r = 0.35, p < 0.001) symptoms, and difficulties in emotion regulation (r = 0.35, p < 0.001). Finally, both discriminant validity with dietary restraint (Gamma = 0.11; p = 0.52) and incremental validity in predicting binge eating severity over emotion dysregulation and psychopathology (b = 0.52; t = 11.11; p < 0.001) were confirmed. Conclusions The Italian mYFAS 2.0 has satisfactory psychometric properties and can be used as a brief instrument for the assessment of addictive eating behaviors when time constraints prevent the use of the original version. Level of Evidence Level V, cross-sectional descriptive study.
