暴饮暴食是超重人群的常见问题，可能会使减肥治疗复杂化。在治疗中解决暴饮暴食需要了解触发这些事件的因素。42名妇女是从一个社区样本中选出的，她们对这项研究表示了兴趣。使用了一种生态瞬时评估（EMA）方法，使参与者能够使用可编程手表在随机时间、所有进食事件之前和暴饮暴食事件之后监测他们的进食、感觉和行为14天。其中，18名BED女性和17名无BED（NBED）女性被保留用于统计分析。最重要的发现是，以这种方式研究时，BED和NBED受试者报告的暴食水平相似。在BED和NBED参与者中，负面情绪、克制和较低水平的积极情绪被认为是暴饮暴食的前因。然而，与NBED参与者相比，在正常饮食和暴饮暴食事件之前，BED参与者的压力和暴饮暴食的欲望更高。EMA是评估参与者自然环境中暴饮暴食行为的一种有价值的方法。BED和NBED参与者在暴饮暴食的频率和暴饮暴食的前因方面表现出更多的相似性。EMA以及BED和NBED参与者之间的相似性可能对BED的诊断有影响。版权所有（C）2001约翰威利父子有限公司和饮食失调协会。
Binge eating is a common problem among overweight people and may complicate weight loss treatment. Addressing binge eating in treatment requires an understanding of the factors that trigger these episodes. Forty-two women were selected from a community sample that expressed interest in the study. An Ecological Momentary Assessment (EMA) method was used that enabled participants to monitor their eating, feelings and behaviours for 14 days, using programmable wristwatches, at random times, before all eating episodes and just after binge eating episodes. Of these, 18 BED women and 17 women with no BED (NBED) were retained for the statistical analyses. The most important finding was that BED and NBED subjects reported similar levels of binge eating when studied in this way. Negative affect, restraint and lower levels of positive affect were noted as antecedents for binge eating in both BED and NBED participants. Stress and desire to binge, however, were higher for BED participants, compared to NBED participants, prior to normal eating and binge eating episodes. EMA was a valuable method to make assessments Of binge eating behaviours in participants' natural environment. BED and NBED participants showed more similarities than differences in terms of the frequency of binge eating as well as binge antecedents. Both EMA as well as the similarities between BED and NBED participants may have implications for the diagnosis of BED. Copyright (C) 2001 John Wiley & Sons, Ltd and Eating Disorders Association.
