目的：作者研究的有效性，无指导的自助作为治疗的第一步暴食症nervosa.Method：共85名妇女与暴食症nervosa谁是在等待名单上的治疗在医院为基础的诊所参加。患者被随机分配接受两种自助手册中的一种或等待列表控制条件8周。其中一个自助手册解决了神经性贪食症的具体症状（认知行为自助），而其他专注于自我主张的技能（非特异性自助）。结果：20例（23.5%）退出了研究。资料采用意向处理分析。虽然暴饮暴食和清洗组的时间相互作用没有统计学意义，简单的影响表明，有一个显着减少症状的频率在两个自助条件在治疗后，但不是在等待名单的条件。在饮食限制、饮食问题、对形状和体重的关注或一般精神病理学方面，没有统计学显著变化。在认知行为自助（53.6%）和非特异性自助（50.0%）条件下，与等待名单条件（31.0%）相比，更大比例的患者报告治疗后暴饮暴食或排便减少至少50%。一个较低的基线知识饮食失调，更多的问题与亲密关系，较高的强迫分数预测更好的response.Conclusions：研究结果表明，神经性贪食症患者的一个亚组可能会受益于无指导的自助作为第一步，在他们的治疗。认知行为自助和非特异性自助的效果相当。
Objective: The authors examined the effectiveness of unguided self-help as a first step in the treatment of bulimia nervosa.Method: A total of 85 women with bulimia nervosa who were on a waiting list for treatment at a hospital-based clinic participated. The patients were randomly assigned to receive one of two self-help manuals or to a waiting list control condition for 8 weeks. One of the self-help manuals addressed the specific symptoms of bulimia nervosa (cognitive behavior self-help), while the other focused on self-assertion skills (nonspecific self-help).Results: Twenty patients (23.5%) dropped out of the study. The data were analyzed with intention-to-treat analysis. Although the group-by-time interaction for binge eating and purging was not statistically significant, simple effects showed that there was a significant reduction in symptom frequency in both self-help conditions at posttreatment but not in the waiting list condition. There were no statistically significant changes in levels of dietary restraint, eating concerns, concerns about shape and weight, or general psychopathology. A greater proportion of patients in the cognitive behavior self-help (53.6%) and nonspecific self-help (50.0%) conditions reported at least a 50% reduction in binge eating or purging at posttreatment, compared with the waiting list condition (31.0%). A lower baseline knowledge about eating disorders, more problems with intimacy, and higher compulsivity scores predicted a better response.Conclusions: The findings suggest that a subgroup of patients with bulimia nervosa may benefit from unguided self-help as a first step in their treatment. Cognitive behavior self-help and nonspecific self-help had equivalent effects.
