To inform the classification of bulimic-type eating disorders not meeting formal diagnostic criteria for bulimia nervosa (BN), levels of eating disorder psychopathology and functional impairment associated with subjective and objective bulimic episodes (SBEs and OBEs) and purging and nonpurging methods of weight control were examined in a large community-based sample of women (n = 5,232).
Participants who reported recurrent bulimic episodes had significantly higher levels of eating disorder psychopathology and functional impairment than those who did not and this was the case whether the episodes were objective or subjective. Similarly, participants who reported the use of extreme weight control behaviors had higher levels of eating disorder psychopathology and functional impairment than those who did not, and this was the case whether purging or nonpurging behaviors were employed. The combination of bulimic episodes and extreme weight control behaviors was associated with particularly high levels of eating disorder psychopathology and functional impairment.
The combination of bulimic episodes, objective or subjective, and extreme weight control behaviors, purging or nonpurging, is significant in terms of impairment in psychosocial functioning among individuals affected by eating disorders not meeting formal diagnostic criteria for BN. The combination of SBEs and extreme weight control behaviors, in particular, warrants further investigation.
为了对不符合神经性贪食症（BN）正式诊断标准的暴食型饮食失调进行分类，在一个大型社区女性样本（n = 5232）中，研究了与主观和客观暴食发作（SBEs和OBEs）以及清除性和非清除性体重控制方法相关的饮食失调心理病理学水平和功能损害情况。
报告反复出现暴食发作的参与者，其饮食失调心理病理学水平和功能损害程度显著高于未出现此类发作的参与者，无论这些发作是客观的还是主观的，情况均如此。同样，报告使用极端体重控制行为的参与者，其饮食失调心理病理学水平和功能损害程度高于未使用此类行为的参与者，无论采用的是清除性还是非清除性行为，情况均如此。暴食发作与极端体重控制行为的组合与特别高的饮食失调心理病理学水平和功能损害相关。
对于不符合BN正式诊断标准的饮食失调个体，主观或客观的暴食发作与清除性或非清除性极端体重控制行为的组合，在心理社会功能损害方面具有重要意义。特别是SBEs与极端体重控制行为的组合，值得进一步研究。
