According to DSM-IV's proposed nosology, binge eating disorder is separable from bulimia nervosa. The basis for separation rests with compensatory behaviors (e.g., induced vomiting)-people with bulimia nervosa engage in compensatory behaviors, whereas those with binge eating disorder do not. We addressed the validity of this nosology.
In three studies on 2,015 young men and women, we used factor-analytic techniques to assess whether bulimic and binge eating symptoms are separable in men and women. Results and Discussion Results of the three studies converged: Although binge eating symptoms may be distinct from bulimic symptoms among young men, the two syndromes are factorially inseparable among young women. Nosologic and sociocultural implications are noted.
根据《精神疾病诊断与统计手册第四版》（DSM-IV）提出的疾病分类法，暴饮暴食症可与神经性贪食症区分开来。区分的依据在于代偿行为（如催吐）——神经性贪食症患者会出现代偿行为，而暴饮暴食症患者则不会。我们探讨了这种疾病分类法的有效性。
在针对2015名年轻男女的三项研究中，我们运用因子分析技术来评估暴饮暴食症状与贪食症状在男性和女性中是否可区分。结果与讨论 三项研究的结果一致：尽管在年轻男性中，暴饮暴食症状可能与贪食症状不同，但在年轻女性中，这两种综合征在因子分析上是不可区分的。文中还提到了疾病分类学和社会文化方面的影响。
