Evidence suggests that both dissociation and negative affect (NA) may precipitate binge eating. The extent to which dissociation may impact the experience of NA around binge eating is unclear. Women with bulimia nervosa completed a 2-week ecological momentary assessment protocol of dissociation, NA, and binge eating. Multilevel modeling was used to examine dissociation as a moderator of NA before and after binge eating. NA was greater at the time of binge eating for participants higher in average dissociation (between subjects) and when momentary dissociation was greater than one's average (within subjects). The trajectory of NA was characterized by a sharper increase before binge eating for participants higher in average dissociation; the NA trajectories were characterized by sharper increases before and decreases after binge eating when momentary dissociation was greater than one's average. Results support the salience of both dissociation and NA in relation to the occurrence of binge eating.
有证据表明，解离和消极情绪（NA）都可能引发暴饮暴食。目前尚不清楚解离在多大程度上会影响暴饮暴食期间消极情绪的体验。神经性贪食症女性完成了一项为期2周的关于解离、消极情绪和暴饮暴食的生态瞬时评估方案。采用多层次模型来检验解离作为暴饮暴食前后消极情绪的调节因素。对于平均解离水平较高（受试者间）的参与者，以及瞬时解离大于其平均水平（受试者内）时，暴饮暴食时的消极情绪更强。对于平均解离水平较高的参与者，消极情绪的轨迹在暴饮暴食前表现为更急剧的增加；当瞬时解离大于其平均水平时，消极情绪的轨迹在暴饮暴食前增加更急剧，在暴饮暴食后减少。结果支持了解离和消极情绪在暴饮暴食发生方面的显著性。
