行为体重管理项目的成本效益和对长期健康的影响取决于治疗后的体重维持情况。越来越多的证据表明，采用接纳与承诺疗法（ACT）的干预措施可能改善长期体重管理。我们开发了一种基于ACT的引导式自助干预措施，以支持近期完成行为减肥项目的成年人。本研究将评估这种干预措施的可行性和可接受性，研究结果将为全面试验的开展提供依据。
这是一项务实的、随机、单盲、平行组、双臂可行性研究，并嵌入了过程评估。我们将招募60名近期完成行为减肥项目的成年人，并使用计算机生成的序列将他们按2∶1的比例随机分配到基于ACT的干预组或标准护理组，分组依据糖尿病状况和性别进行分层。将使用在线问卷完成基线和6个月的测量。将对部分参与者和教练在3个月（干预中期）和6个月（干预后期）时的经历进行定性访谈。将通过一系列结果评估干预措施的可行性和可接受性以及全面试验的情况，这些结果包括对干预措施的依从性和参与度、招募和留存率、各结果指标缺失数据的比例、参与者对干预措施和研究的体验以及教练提供干预支持的体验。将对定量和定性研究结果进行整合和总结，以便对主要的可行性评估结果进行解读。将使用信息价值方法来估计与干预措施成本效益相关的决策不确定性，并确定确定性试验的价值。
2021年3月15日获得剑桥南部研究伦理委员会的伦理批准（21/EE/0024）。本方案（第2版）于2021年4月19日获得批准。研究结果将发表在经同行评审的科学期刊上，并酌情传达给其他利益相关者。

The cost-effectiveness and long-term health impact of behavioural weight management programmes depends on post-treatment weight-loss maintenance. Growing evidence suggests that interventions using acceptance and commitment therapy (ACT) could improve long-term weight management. We developed an ACT-based, guided self-help intervention to support adults who have recently completed a behavioural weight loss programme. This study will assess the feasibility and acceptability of this type of intervention and findings will inform the development of a full-scale trial. This is a pragmatic, randomised, single-blind, parallel group, two-arm, feasibility study with an embedded process evaluation. We will recruit and randomise 60 adults who have recently completed a behavioural weight loss programme to the ACT-based intervention or standard care, using a computer-generated sequence with 2:1 allocation stratified by diabetes status and sex. Baseline and 6-month measurements will be completed using online questionnaires. Qualitative interviews will be conducted with a subsample of participants and coaches about their experiences at 3 (mid-intervention) and 6 (postintervention) months. Feasibility and acceptability of the intervention, and a full-scale trial will be assessed using a number of outcomes, including adherence to, and engagement with the intervention, recruitment and retention rates, proportion of missing data for each outcome measure, participants’ experiences of the intervention and study, and coaches’ experiences of delivering intervention support. Quantitative and qualitative findings will be integrated and summarised to contribute to the interpretation of the main feasibility evaluation findings. Value of information methods will be used to estimate the decision uncertainty associated with the intervention’s cost-effectiveness and determine the value of a definitive trial. Ethical approval was received from Cambridge South Research Ethics Committee on 15/03/2021 (21/EE/0024). This protocol (V.2) was approved on 19 April 2021. Findings will be published in peer-reviewed scientific journals and communicated to other stakeholders as appropriate. ISRCTN12685964.
