Body-image disturbance is a core aspect of eating disorders, yet the clinical manifestations of individuals' weight and shape concerns are complex, vary considerably, and are poorly understood by clinicians and researchers. This study aimed to distinguish different aspects of body-image disturbance-including weight/shape dissatisfaction, weight/shape overvaluation, weight/shape preoccupation, and fear of weight gain-in patients with binge-eating disorder (BED). Examining how each specific body image construct relates to biopsychosocial features of BED could contribute to the refinement of conceptualization and treatment planning.
The current study assessed body-image disturbance and eating-disorder psychopathology in 748 treatment-seeking patients with BED using established investigator-based interviews reliably administered by doctoral clinicians.
The 4 body image constructs, although related to one another, showed some important similarities in associations with biopsychosocial clinical features, as well as some important distinctions. The relation between overvaluation and self-esteem was, as conceptualized, more strongly negative than for other body image variables, and preoccupation was more associated than other body image variables with eating concerns. Biopsychosocial features of BED were associated with different forms of body-image disturbance, but associations of body image variables with body mass index (BMI) were not significant and associations with binge-eating frequency did not differ across body image variables.
Manifestations of body-image disturbance in BED are complex and understanding the distinctions between different body image constructs can contribute to treatment formulation. (PsycINFO Database Record
体像障碍是进食障碍的核心方面，但个体对体重和体型的关注的临床表现复杂多样，临床医生和研究人员对此了解甚少。本研究旨在区分暴食障碍（BED）患者体像障碍的不同方面，包括体重/体型不满、体重/体型高估、体重/体型过度关注和对体重增加的恐惧。研究每种特定的体像结构与 BED 的生物心理社会特征的关系有助于完善概念化和治疗计划。
本研究使用经过可靠验证的基于研究者的访谈，对 748 名寻求治疗的 BED 患者进行了体像障碍和饮食障碍心理病理学评估，这些访谈由博士级临床医生可靠地进行。
尽管这 4 个体像结构相互关联，但它们与生物心理社会临床特征的关联存在一些重要的相似之处，也存在一些重要的区别。高估与自尊的关系，如其概念所设想的，比其他体像变量的关系更为负面，而过度关注比其他体像变量更与饮食问题相关。BED 的生物心理社会特征与不同形式的体像障碍有关，但体像变量与体重指数（BMI）的关联并不显著，与暴食频率的关联在体像变量之间也没有差异。
BED 中体像障碍的表现是复杂的，了解不同体像结构之间的区别有助于治疗方案的制定。
