Inpatient (n = 27) and outpatient (n = 22) cognitive-behavior therapy programs for bulimia nervosa were evaluated in an uncontrolled experiment. Both treatment conditions included exposure with response prevention and cognitive restructuring. Inpatient treatment had a mean length of stay of 5 weeks. Outpatient treatment lasted 15 weeks. Both groups were followed after the end of treatment. The results showed that both programs were effective in reducing problems associated with bulimia nervosa. The inpatient program led to very rapid progress, whereas the outpatient program led to more gradual improvement. There was, however, a trend toward relapse for inpatients. Other psychological disturbances, (e.g., depression) were improved after inpatient, but not outpatient, treatment. These data were discussed in terms of their implications for treatment planning for cases of bulimia nervosa.
在一项非对照实验中，对神经性贪食症的住院（n = 27）和门诊（n = 22）认知行为治疗项目进行了评估。两种治疗方案均包括暴露与反应阻止以及认知重构。住院治疗的平均住院时长为5周。门诊治疗持续15周。两组在治疗结束后均接受随访。结果表明，两种方案在减轻与神经性贪食症相关的问题方面均有效。住院治疗方案进展非常迅速，而门诊治疗方案则带来更渐进的改善。然而，住院患者有复发的趋势。其他心理障碍（如抑郁症）在住院治疗后有所改善，但门诊治疗后未改善。根据这些数据对神经性贪食症病例治疗规划的意义进行了讨论。
