This study examined the interpersonal model of binge eating (Wilfley et al., Interpersonal Psychotherapy for Group, New York: Basic Books, 2000; Wilfley et al., Arch Gen Psychiatry, 8, 713-721, 2002; Elliott et al., Behav Res Ther, 48, 424-428, 2010) which posits that interpersonal problems lead to negative affect which, in turn, triggers disordered eating.
The model was tested using data from 350 women obtained via an internet assessment method. Analyses examined direct and indirect effects, via depressive/negative affect, of interpersonal problems, including domains of affiliation and dominance on loss of control over eating, binge eating, and eating disorder psychopathology.
Interpersonal problems showed significant effects on binge eating and eating disorder psychopathology that were statistically mediated by depressive/negative affect. Affiliation showed significant effects on binge eating and eating disorder psychopathology with low affiliation effects statistically mediated by depressive/negative affect and high affiliation effects independent of depressive/negative affect.
These findings support the interpersonal model of binge eating and highlight the importance of examining specific types of interpersonal problems in understanding heterogeneity of individuals with eating disorder psychopathology.
本研究检验了暴食的人际模型（Wilfley 等人，人际心理治疗团体，纽约：基础书籍，2000 年；Wilfley 等人，《普通精神病学档案》，8，713-721，2002 年；Elliott 等人，《行为研究与治疗》，48，424-428，2010 年），该模型认为人际问题会导致负面情绪，而负面情绪又会引发饮食失调。
该模型使用通过互联网评估方法获得的 350 名女性的数据进行了检验。分析通过抑郁/负面情绪，检验了人际问题，包括亲和和支配领域，对失控进食、暴食和饮食障碍心理病理学的直接和间接影响。
人际问题对暴食和饮食障碍心理病理学有显著影响，抑郁/负面情绪在统计学上起到中介作用。亲和度对暴食和饮食障碍心理病理学有显著影响，低亲和度的影响通过抑郁/负面情绪中介，高亲和度的影响独立于抑郁/负面情绪。
这些发现支持暴食的人际模型，并强调了在理解具有饮食障碍心理病理学的个体的异质性时，检查特定类型的人际问题的重要性。
