目的：研究神经性暴食症的自然病程特征，并找出预测暴食症持续存在的潜在维持因素，以促进对延续进食障碍的过程的认识，并设计更有效的治疗方法。方法：我们对96名有阈值或阈值下神经性暴食症的妇女进行了为期一年的季度访谈。结果：每个月都有很高的缓解率和复发率，但在大约4个月的症状禁止期后，缓解变得更有可能持续。瘦-理想内化的初始水平、对进食回报的期望以及暴饮暴食的频率预示着暴饮暴食的缓解时间更长。饮食约束和代偿行为频率的初始升高预示着代偿行为的缓解时间更长。讨论：结果表明，如果饮食障碍的治疗能够减少瘦理想内化、进食期望和无效节食，并迅速停止暴食和代偿行为，那么治疗可能更有效。(C)2008年，威利期刊公司。
Objective: To characterize the natural course of bulimia nervosa and identify potential maintenance factors that predict persistence of bulimic pathology in order to advance knowledge of processes that perpetuate this eating disturbance and permit the design of more efficacious treatments.Method: We followed 96 women with threshold or subthreshold bulimia nervosa over a 1-year period with quarterly interviews.Results: There were high rates of remission and relapse on a month-to-month basis, but remission became more likely to persist after a period of approximately 4 months of symptom abstinence. Initial elevations in thin-ideal internalization, expectations for reward from eating, and binge frequency predicted greater time to remission of binge eating. Initial elevations in dietary restraint and compensatory behavior frequency predicted greater time to remission of compensatory behaviors.Discussion: Results imply that treatments for eating disorder may be more effective if they can reduce thin-ideal internalization, eating expectancies, and ineffective dieting and produce rapid cessation of binge eating and compensatory behaviors.
