The present study examined whether additional sessions of group psychotherapy process (PP) would incrementally benefit bulimia nervosa (BN) subjects over and above that which is achieved through a course of brief group psychoeducation (PE).
Utilizing a quasi-experimental design, the first cohort of 40 BN subjects completed five-session PE-alone groups that were highly didactic and explicitly devoid of group process work. The second cohort of 41 BN subjects completed 12-session PE + PP groups that integrated PE with more conventional cognitive-behavioral group process interventions.
Both treatments were associated with comparable levels of change on measures of specific and nonspecific psychopathology. Furthermore, the two treatments did not differ in rates of premature termination, in rates of remission in eating symptoms, in rates of normalization of scores on psychometric measures, or in consumer evaluation of the treatments.
While subjects value the opportunity to engage in psychotherapy process with other group members, the addition of seven such sessions offers no enhanced therapeutic benefit over five sessions of group PE.
本研究探讨了在短期团体心理教育（PE）课程基础上，额外增加团体心理治疗过程（PP）环节是否会让神经性贪食症（BN）患者获得更多益处。
采用准实验设计，第一组40名BN患者完成了仅包含五节课程的PE组，课程具有很强的讲授性且明确不涉及团体过程工作。第二组41名BN患者完成了包含12节课程的PE + PP组，该组将PE与更传统的认知行为团体过程干预相结合。
两种治疗方法在特定和非特定精神病理学测量指标上的变化水平相当。此外，两种治疗方法在提前终止治疗的发生率、饮食症状缓解率、心理测量指标分数正常化率或患者对治疗的评价方面均无差异。
虽然患者重视与其他团体成员一起参与心理治疗过程的机会，但在五节团体PE课程基础上再增加七节这样的课程并不会带来更大的治疗益处。
