Abstract Obesity is a serious risk factor for cardiovascular disease but few people have access to behavioral treatments. Technology-delivered weight loss programs have the potential to increase reach and early studies reveal modest impact. Less impressive outcomes have been produced by commercial weight loss mobile apps perhaps because they focus mostly on self-monitoring which in spite of being an essential component of behavioral weight loss interventions, has poor efficacy as a standalone intervention. Generating technology that can assist in a wider range of behavioral strategies, particularly in ways that reduce burden could increase the efficacy of technology-supported interventions. Our previous work has focused on developing technology- supported tools that help participants implement stimulus control and problem solving, two behavior change strategies heavily leveraged in traditional behavioral weight loss interventions. The goal of this application is to test the feasibility and acceptability of a comprehensive technology-delivered weight loss intervention that systematically assists users in implementing 3 essential behavioral weight loss strategies (self-monitoring, stimulus control, problem solving) and uses peer mentoring training to engage peers to assist each other in implementing these strategies. To minimize costs and maximize dissemination potential, we leverage both commercially available technologies (e.g., MyFitnessPal and Facebook) and our home grown technologies to accomplish this. The proposed technology-delivered program includes 1) MyFitnessPal for diet and exercise self-monitoring, 2) our Building Habits Together app, which includes two features we previously developed to assist participants in the behavioral strategies of stimulus control and problem solving, 3) Facebook to provide a platform to deliver intervention messages, provide counseling, and engage participants, and 4) brief peer mentor training to increase peer-to-peer interactions relating to behavioral strategies. Once refined and pre- piloted in a single arm trial of a 6-week version, we will evaluate the feasibility and acceptability of Building Habits Together relative to a standard technology-delivered weight loss intervention in a 6-month pilot randomized trial. Feasibility outcomes include use of the mobile app features (dietary self-monitoring, slip tracker, and problem solving), retention, engagement (problem solving, peer mentoring), acceptability, weight loss-related problem solving skills, burden, contamination, and counselor time. Results will provide preliminary data to support a randomized trial testing whether the Building Habits Together intervention improves weight loss outcomes over 1 year relative to a standard technology-delivered weight loss intervention. The result would then be a low cost, low user burden, entirely remotely-delivered behavioral weight loss intervention that could be readily adopted in a variety of settings.

抽象的 肥胖是心血管疾病的严重危险因素，但很少有人能够获得行为干预 治疗。技术提供的减肥计划有可能扩大影响范围和早期研究 揭示出适度的影响。商业减肥移动应用程序产生的效果不太令人印象深刻 也许是因为他们主要关注自我监控，尽管这是自我监控的重要组成部分 行为减肥干预措施作为独立干预措施的效果较差。发电技术 这可以帮助制定更广泛的行为策略，特别是减轻负担的方式 技术支持的干预措施的有效性。我们之前的工作重点是开发技术- 支持的工具可帮助参与者实施刺激控制和问题解决，两种行为改变 传统行为减肥干预措施中大量采用的策略。该应用程序的目标是 测试综合技术减肥干预措施的可行性和可接受性 系统地协助用户实施 3 种基本的行为减肥策略（自我监控、 刺激控制、问题解决），并利用同伴指导培训让同伴互相帮助 实施这些战略。为了最大限度地降低成本并最大限度地发挥传播潜力，我们利用两者 商业可用的技术（例如 MyFitnessPal 和 Facebook）和我们的本土技术 完成这个。拟议的技术交付计划包括 1) 用于饮食和锻炼的 MyFitnessPal 自我监控，2)​​ 我们的 Building Habits Together 应用程序，其中包括我们之前开发的两个功能 协助参与者制定刺激控制和问题解决的行为策略，3）Facebook提供 一个传递干预信息、提供咨询和吸引参与者的平台，以及 4) 简短的同行交流 导师培训，以增加与行为策略相关的同伴互动。一旦精炼和预 在为期 6 周的版本的单臂试验中进行试点，我们将评估构建的可行性和可接受性 与标准技术在为期 6 个月的试点中提供的减肥干预措施相关的“习惯在一起” 随机试验。可行性结果包括使用移动应用程序功能（饮食自我监测、滑动 跟踪器和问题解决）、保留率、参与度（问题解决、同伴指导）、可接受性、权重 与损失相关的问题解决技能、负担、污染和咨询时间。结果将提供初步 支持一项随机试验的数据，该试验测试“一起养成习惯”干预是否可以改善体重 相对于标准技术提供的减肥干预措施，一年内的减重结果。结果 那么这将是一种低成本、低用户负担、完全远程提供的行为减肥干预措施 可以很容易地在各种环境中采用。
