Food addiction (FA) and binge eating disorder (BED) co-occur and share compulsive eating symptoms. When using an FA measure, it is important to evaluate its performance in a population presenting compulsive eating. The study aims to validate the Addiction-like Eating Behavior Scale (AEBS) among a clinical sample characterized by compulsive eating and overweight/obesity and to evaluate its incremental validity over the Yale Food Addiction Scale 2.0 (YFAS). Patients seeking help for compulsive eating (n = 220), between January 2020 and July 2023, completed online questionnaires, including FA, compulsive eating, and BMI evaluations. The factor structure, internal consistency, and convergent, divergent, and incremental validity were tested. The sample had a mean age of 44.4 years old (SD = 12.7) and a mean BMI of 38.2 (SD = 8.0). The two-factor structure provided a good fit for the data, with factor loadings from 0.55 to 0.82 (except for item 15) and the internal consistency was high (ω = 0.84-0.89). The AEBS was positively correlated with the YFAS (r = 0.66), binge eating (r = 0.67), grazing (r = 0.47), craving (r = 0.74), and BMI (r = 0.26), and negatively correlated with dietary restraint (r = -0.37), supporting good convergent and divergent validity. For each measure of compulsive eating, linear regression showed that the AEBS "appetite drive" subscale had a unique contribution over the YFAS. This study provided evidence that the AEBS is a valid measure among a clinical sample of patients with compulsive eating and overweight/obesity. However, questions remain as to whether the AEBS is a measure of FA or compulsive eating.
食物成瘾（FA）和暴食障碍（BED）同时存在，并具有强迫性进食的症状。在使用 FA 测量工具时，评估其在具有强迫性进食的人群中的表现非常重要。本研究旨在验证在具有强迫性进食和超重/肥胖的临床样本中，类似成瘾的进食行为量表（AEBS）的有效性，并评估其在耶鲁食物成瘾量表 2.0（YFAS）上的增量有效性。2020 年 1 月至 2023 年 7 月，寻求治疗强迫性进食的患者（n = 220）在线完成了 FA、强迫性进食和 BMI 评估等问卷。测试了其因子结构、内部一致性、收敛、发散和增量有效性。样本的平均年龄为 44.4 岁（SD = 12.7），平均 BMI 为 38.2（SD = 8.0）。双因素结构为数据提供了良好的拟合，因子负荷从 0.55 到 0.82（除项目 15 外），内部一致性较高（ω = 0.84-0.89）。AEBS 与 YFAS（r = 0.66）、暴食（r = 0.67）、放牧（r = 0.47）、渴望（r = 0.74）和 BMI（r = 0.26）呈正相关，与饮食抑制（r = -0.37）呈负相关，支持良好的收敛和发散有效性。对于强迫性进食的每个测量，线性回归表明 AEBS 的“食欲驱动”子量表对 YFAS 有独特的贡献。本研究为 AEBS 在具有强迫性进食和超重/肥胖的临床样本中是一种有效的测量工具提供了证据。然而，AEBS 是 FA 还是强迫性进食的测量工具仍存在疑问。
