To define the utility of the DSM-IV-TR definition of binge eating, as it applies to anorexia nervosa (AN) and underweight eating disorder not otherwise specified (ED-NOS).
We investigated the psychopathological features associated with bulimic episodes in 105 underweight individuals with eating disorders who reported regular objective bulimic episodes with or without subjective bulimic episodes (OBE group, n = 33), regular subjective bulimic episodes only (SBE group, n = 36) and neither objective nor subjective bulimic episodes (n = 36, no-RBE group). The Eating Disorder Examination (EDE), anxiety, depression, and personality tests were administered before and upon completion of inpatient cognitive behavior therapy (CBT) treatment 6 months later.
Compared with the SBE group, OBE subjects had higher body mass index, and more frequent self-induced vomiting, while both OBE and SBE groups had more severe eating disorder psychopathology and lower self-directness than the no-RBE group. Dropout rates and outcomes in response to inpatient CBT were similar in the three groups.
Despite a few significant differences at baseline, the similar outcome in response to CBT indicates that categorizing patients with underweight eating disorder on the basis of the type or frequency of bulimic episodes is of limited clinical utility.
确定 DSM-IV-TR 中关于暴食的定义在神经性厌食症（AN）和未特定的体重减轻型进食障碍（ED-NOS）中的应用效用。
我们调查了 105 名体重减轻的进食障碍患者中与暴食发作相关的精神病理学特征，这些患者报告有规律的客观暴食发作（伴有或不伴有主观暴食发作）（OBE 组，n=33）、有规律的主观暴食发作（SBE 组，n=36）和既无客观也无主观暴食发作（无-RBE 组，n=36）。在开始住院认知行为治疗（CBT）治疗前和 6 个月后完成治疗时，对患者进行了饮食障碍检查（EDE）、焦虑、抑郁和人格测试。
与 SBE 组相比，OBE 组的体重指数更高，自我诱导呕吐的频率更高，而 OBE 和 SBE 组的饮食障碍心理病理学更严重，自我导向性更低，与无-RBE 组相比。三组的辍学率和对住院 CBT 的反应结果相似。
尽管在基线时有一些显著差异，但对 CBT 的类似反应表明，根据暴食发作的类型或频率对体重减轻型进食障碍患者进行分类的临床效用有限。
