体重反弹是常见的行为肥胖治疗后，削弱了许多最初的体重减轻的好处。本文描述了一项随机对照试验，将评估两种基于接受和承诺疗法（ACT）和自我调节（SR）的低接触减肥维持干预措施的有效性。还将评价潜在的作用机制和治疗效果的调节剂。超重或肥胖的成人（预计N=480）将完成最初的3个月在线减肥计划（第1阶段）。体重减轻≥4 kg的受试者（预期N=288）将随机接受ACT或SR体重减轻维持干预。这两种干预措施都需要四次2.5小时的面对面小组研讨会和6个月的电子邮件联系。将在I期基线、I期完成/随机化前以及随机化后6、12、18、24和30个月进行评估。主要结局为从随机化至30个月期间的体重变化。潜在的过程措施，包括基于ACT的结构（例如，心理接受度、价值观一致的行为）、自我衡量频率和动机也将被评估，潜在的调节者（例如，初始体重减轻）。本研究将比较两种干预方法（ACT和SR）的有效性，以可扩展的研讨会形式提供长期减肥维持。未来的研究可以检查这些方法在真实的世界环境中的功效和成本效益。
Weight regain is common following behavioral obesity treatment and attenuates many of the benefits of initial weight loss. This paper describes a randomized controlled trial that will evaluate the efficacy of two low-contact weight loss maintenance interventions based on Acceptance and Commitment Therapy (ACT) and self-regulation (SR). Potential mechanisms of action and moderators of treatment effects will also be evaluated. Adults (anticipated N=480) with overweight or obesity will complete an initial 3-month online weight loss program (Phase 1). Participants who achieve ≥4 kg weight loss (anticipated N=288) will then be randomized to an ACT or SR weight loss maintenance intervention. Both interventions will entail four 2.5 hour, face-to-face, group-based workshop sessions and 6 months of email contact. Assessments will be conducted at phase 1 baseline, phase 1 completion/pre-randomization, and 6, 12, 18, 24, and 30 months post-randomization. The primary outcome will be weight change for the period from randomization to 30 months. Potential process measures including ACT-based constructs (e.g., psychological acceptance, values-consistent behavior), self-weighing frequency, and motivation will be also be assessed, as will potential moderators (e.g., initial weight loss). This study will compare the efficacy of two intervention approaches (ACT and SR) delivered in a scalable workshop format for long-term weight loss maintenance. Future research could examine efficacy and cost-effectiveness of these approaches in real world settings.
