A first approach of a phenotypic characterization of food addiction (FA) found three clusters (dysfunctional, moderate and functional). Based on this previous classification, the aim of the present study is to explore treatment responses in the sample diagnosed with Eating Disorder(ED) of different FA profiles.
The sample was composed of 157 ED patients with FA positive, 90 with bulimia nervosa (BN), 36 with binge eating disorder (BED), and 31 with other specified feeding or eating disorders (OSFED). Different clinical variables and outcome indicators were evaluated.
The clinical profile of the clusters present similar characteristics with the prior study, having the dysfunctional cluster the highest ED symptom levels, the worse psychopathology global state, and dysfunctional personality traits, while the functional one the lowest ED severity level, best psychological state, and more functional personality traits. The dysfunctional cluster was the one with lowest rates of full remission, the moderate one the higher rates of dropouts, and the functional one the highest of full remission.
The results concerning treatment outcome were concordant with the severity of the FA clusters, being that the dysfunctional and moderate ones had worst treatment responses than the functional one.
对食物成瘾（FA）表型特征的初步研究发现了三个聚类（功能失调型、中度型和功能型）。基于这一先前的分类，本研究旨在探讨不同 FA 特征的饮食障碍（ED）患者样本的治疗反应。
该样本由 157 名 FA 阳性的 ED 患者、90 名神经性贪食症（BN）患者、36 名暴食障碍（BED）患者和 31 名其他特定进食或饮食障碍（OSFED）患者组成。评估了不同的临床变量和结果指标。
聚类的临床特征与先前的研究相似，功能失调型聚类的 ED 症状水平最高，整体心理病理状态最差，且具有功能失调的人格特征，而功能型聚类的 ED 严重程度最低，心理状态最好，且具有更多功能健全的人格特征。功能失调型聚类的完全缓解率最低，中度聚类的辍学率最高，而功能型聚类的完全缓解率最高。
治疗结果的结果与 FA 聚类的严重程度一致，功能失调型和中度型的治疗反应比功能型差。
