Acceptance-based behavior treatment: An innovative weight control intervention

描述（由申请人提供）：美国正处于肥胖症流行之中，迫切需要解决这一问题的创新方法。虽然传统的行为治疗是最经经验验证的减肥方法，但它通常会导致体重控制行为的维持不良，并且在三到五年内，这些计划的大多数参与者将重新获得他们最初失去的体重。标准的行为减肥治疗可能会得到改善，包括（a）加强参与者对行为改变的承诺，（B）建立痛苦容忍技能和（c）促进饮食行为和目标的意识。这些组成部分在行为疗法的新模式中得到了很好的体现，这些模式结合了正念、经验意识、改变行为的价值观、接受痛苦的内部体验以及愿意容忍痛苦以服务于有价值的行为改变的原则和技术。该项目的主要目标是确定一个创新的行为减肥计划，结合行为治疗领域的新发展，比标准的行为治疗产生上级体重控制。将通过大费城社区的媒体广告招募128名BMI为27至40 kg/m2的成年人参与本研究。参与者将被随机分配到两个条件之一：标准行为治疗（SBT）或基于接受的行为治疗（ABBT）。每种治疗将以每周一次，然后每两周一次的方式以组的形式进行。治疗将持续40周：第1-20周专注于减肥，而第21-40周部分转移到减肥维持。将在基线、10周、20周（即，减肥治疗结束），40周（即，体重减轻维持治疗结束时）和6个月随访时。公共卫生相关性：肥胖正在达到流行病的程度。肥胖的标准行为治疗有效地诱导体重减轻，但长期维持体重减轻仍然具有挑战性。这项研究的主要目的是开发和初步评估一种创新的、基于接受度的行为减肥治疗方法，旨在促进长期坚持健康饮食和体育活动行为，从而改善减肥效果。

DESCRIPTION (provided by applicant): The United States is in the midst of an obesity epidemic and innovative approaches to address this problem are urgently needed. Although traditional behavioral treatment is the most empirically validated approach for weight loss, it typically results in poor maintenance of weight control behaviors, and within three to five years most participants in these programs will have regained the weight they originally lost. Standard behavioral weight loss treatment might be improved by incorporating components that (a) bolster participants' commitment to behavior change, (b) build distress tolerance skills and (c) promote mindful awareness of eating behaviors and goals. Such components are well- represented within newer models of behavior therapies that incorporate principles and technologies of mindfulness, experiential awareness, values for changing behavior, acceptance of distressing internal experiences, and willingness to tolerate distress in the service of valued behavior change. The primary goal of the proposed project is to determine if an innovative behavioral weight loss program that incorporates new developments from the field of behavior therapy produces superior weight control than standard behavioral treatment. A sample of 128 adults with a BMI of 27 to 40 kg/m2 will be recruited via media advertisements in the greater Philadelphia community to participate in this study. Participants will be randomly assigned to one of two conditions: standard behavioral treatment (SBT) or acceptance-based behavioral treatment (ABBT). Each treatment will be delivered in a group format on a weekly, and then bi-weekly, basis. Treatment will last 40 weeks: weeks 1-20 focus on weight loss, while weeks 21-40 partially shift focus to weight loss maintenance. Assessments will be completed at baseline, 10 weeks, 20 weeks (i.e., end of weight loss treatment), 40 weeks (i.e., end of weight loss maintenance treatment), and at 6-month follow-up. PUBLIC HEALTH RELEVANCE: Obesity is reaching epidemic proportions. Standard behavioral treatment for obesity effectively induces weight loss, but long-term maintenance of weight loss remains challenging. The primary aim of the proposed study is to develop and conduct a preliminary evaluation of an innovative, acceptance-based behavioral weight loss treatment that is designed to promote long-term adherence to healthy eating and physical activity behaviors and thereby improve weight loss maintenance.
