The present study examined the prevalence of binge eating disorder (BED) among 192 obese individuals seeking treatment in a university-based eating disorders program. Subjects responded to a self-report questionnaire on the presence and severity of binge eating and were divided into two groups: (a) 48 non-binge eaters and (b) 144 binge eaters, 72 of whom met criteria for BED. Binge eaters reported earlier onset of obesity, higher levels of psychopathology, and less competence in relation to weight control. Comparison between the 72 individuals diagnosed with BED and the 72 binge eaters not meeting BED criteria indicated that the former group evidenced more severe binge eating and a higher level of depression. Given the differences across a range of psychological variables between binge eaters and non-binge eaters, these findings support the clinical and research value of BED as a new diagnostic category. However, they also indicate that severity of binge eating, regardless of frequency and associated behavioral features, is the most important distinguishing characteristic. Further research is needed to determine the most appropriate threshold for BED diagnosis.
本研究调查了在一个大学饮食失调项目中寻求治疗的192名肥胖个体中暴饮暴食症（BED）的患病率。受试者对一份关于暴饮暴食的存在及严重程度的自我报告问卷做出回应，并被分为两组：（a）48名非暴饮暴食者和（b）144名暴饮暴食者，其中72人符合暴饮暴食症的标准。暴饮暴食者报告称肥胖发病较早，心理病理学水平较高，且在体重控制方面能力较低。对72名被诊断为暴饮暴食症的个体与72名不符合暴饮暴食症标准的暴饮暴食者进行比较，结果表明前一组的暴饮暴食情况更严重，抑郁水平更高。鉴于暴饮暴食者和非暴饮暴食者在一系列心理变量上存在差异，这些发现支持了将暴饮暴食症作为一种新诊断类别的临床和研究价值。然而，它们也表明，无论频率和相关行为特征如何，暴饮暴食的严重程度是最重要的区别特征。需要进一步研究以确定暴饮暴食症诊断的最合适阈值。
