Abstract

Objective: Test whether a group-delivered dissonance-based transdiagnostic eating disorder treatment, Body Project Treatment (BPT), produces greater reductions in eating disorder symptoms and higher abstinence from eating disorder behaviors and remittance from eating disorder diagnoses than group-delivered transdiagnostic interpersonal psychotherapy (IPT).

Method: Women with a range of eating disorders (N = 73) were randomized to 8-week group-implemented BPT or IPT and completed surveys and masked diagnostic interviews at pretest, posttest, and 6-month follow-up.

Results: Participants randomized to BPT versus IPT showed significantly greater reductions in eating disorder symptoms (d = -.75), pursuit of the thin ideal (d = -.87), anxiety symptoms (d = -.76), and social impairment (d = -.59) through 6-month follow-up. By end of treatment, participants randomized to the BPT versus IPT did not significantly differ on abstinence from binge eating and purging (49% vs. 40%, respectively) or remittance from eating disorder diagnoses (54% vs. 40%, respectively). Participants randomized to BPT versus IPT did not differ significantly in average session attendance (5.8 vs. 6.9, respectively) or average homework assignments completed (4.6 vs. 5.6, respectively). The within-condition reductions in eating disorder symptoms for BPT did not significantly differ when implemented in person versus via synchronous video telepsychiatry (d = -1.39 vs. -1.09, respectively), though these effects should be considered preliminary because of the small cell sizes.

Conclusions: The evidence that BPT produces greater reductions in eating disorder symptoms, pursuit of the thin ideal, anxiety symptoms, and social impairment than IPT is encouraging because it provides some assurance that the effects are present equating for the effects of expectancies, demand characteristics, and nonspecific factors.

两组传递的跨诊断性饮食障碍治疗的随机试验:基于不和谐的治疗与人际心理治疗。

目的:检验团体提供的基于失调的跨诊断性饮食失调治疗，身体项目治疗(BPT)是否比团体提供的跨诊断性人际心理治疗(IPT)更能减轻饮食失调症状，更能戒除饮食失调行为和减轻饮食失调诊断。方法:有一系列饮食失调的女性(N = 73)被随机分配到8周的BPT或IPT组，并在测试前、测试后和6个月的随访中完成调查和隐蔽性诊断访谈。结果:通过6个月的随访，随机分配到BPT组和IPT组的参与者在饮食失调症状(d = - 0.75)、追求理想身材(d = - 0.87)、焦虑症状(d = - 0.76)和社交障碍(d = - 0.59)方面表现出显著更大的减轻。在治疗结束时，随机分配到BPT和IPT的参与者在暴食和排空的戒断(分别为49%和40%)或饮食失调诊断的缓解(分别为54%和40%)方面没有显著差异。随机分配到BPT和IPT的参与者在平均出勤率(分别为5.8对6.9)或平均家庭作业完成(分别为4.6对5.6)方面没有显着差异。与同步视频远程精神病学相比，亲自实施BPT的进食障碍症状的条件内减少没有显着差异(d分别= -1.39和-1.09)，尽管这些效果应被认为是初步的，因为细胞大小较小。结论:与IPT相比，BPT在饮食失调症状、追求瘦的理想、焦虑症状和社交障碍方面的效果更大，这一证据令人鼓舞，因为它提供了一些保证，即预期、需求特征和非特异性因素的效果是相等的。(PsycInfo数据库记录(c) 2023 APA，版权所有)。

期刊介绍： The Journal of Consulting and Clinical Psychology® (JCCP) publishes original contributions on the following topics: the development, validity, and use of techniques of diagnosis and treatment of disordered behaviorstudies of a variety of populations that have clinical interest, including but not limited to medical patients, ethnic minorities, persons with serious mental illness, and community samplesstudies that have a cross-cultural or demographic focus and are of interest for treating behavior disordersstudies of personality and of its assessment and development where these have a clear bearing on problems of clinical dysfunction and treatmentstudies of gender, ethnicity, or sexual orientation that have a clear bearing on diagnosis, assessment, and treatmentstudies of psychosocial aspects of health behaviors. Studies that focus on populations that fall anywhere within the lifespan are considered. JCCP welcomes submissions on treatment and prevention in all areas of clinical and clinical–health psychology and especially on topics that appeal to a broad clinical–scientist and practitioner audience. JCCP encourages the submission of theory–based interventions, studies that investigate mechanisms of change, and studies of the effectiveness of treatments in real-world settings. JCCP recommends that authors of clinical trials pre-register their studies with an appropriate clinical trial registry (e.g., ClinicalTrials.gov, ClinicalTrialsRegister.eu) though both registered and unregistered trials will continue to be considered at this time.
