Abstract In a lifestyle modification program, contact with an interventionist (e.g., weight loss coach) creates a sense of supportive accountability that can facilitate behavior change and weight loss. Sustaining a strong sense of supportive accountability after face-to-face intervention contact ends has the potential to improve outcomes during the notoriously difficult weight loss maintenance period. One innovative way of facilitating supportive accountability is providing participants with digital tools that objectively measure weight and PA and track food intake in real-time, making the data from those tools automatically and continuously available to coaches, and designing the timing and content of intervention contacts such that they are responsive to the shared data. Although tools that allow for data sharing from sensors and Internet-based applications are readily available, the ways in which they are integrated into intervention contacts in a lifestyle modification program are not yet optimized, and research has not systematically evaluated the effect of data sharing on behavior. Overweight and obese participants (n = 90) will be recruited from the community for a small RCT in order to test the feasibility, acceptability, efficacy, and mechanisms of action of a lifestyle modification intervention enhanced with data sharing. In weeks 1-12 of the program (i.e., Phase I), all participants will attend 12 weekly, face-to- face, group-based behavioral treatment sessions to induce weight loss. Participants will be provided with a wireless body weight scale, PA sensor, and digital food record app and instructed to use them daily use for self-monitoring purposes. In Phase II (weeks 13-52), participants will be randomly assigned to the standard (LM) or enhanced version of remote lifestyle modification (LM+SHARE). Neither condition will have face-to- face intervention contact during Phase II; remote intervention contact will consist of brief phone calls and text messages provided by the participant's coach. Participants in both conditions will be prescribed continued daily use of the three self-monitoring devices. In the standard LM condition, no digital data from these devices will be directly shared with coaches; intervention encounters will be informed only by the infrequent, delayed self- report of participants (which is the current standard of long-term obesity care), and timing of text messages will be fixed. In LM+SHARE, the digital tools will automatically and continuously transmit body weight, PA, and food record data to the coach. In LM+SHARE, supportive accountability will be enhanced in three ways: 1) participants will receive automated alerts after coaches view their data, 2) timing of personalized text messages from coaches will be responsive to clinically notable change in weight, PA, calorie intake, or use of scale, PA sensor, or food record tool, and 3) content of the text messages and phone calls will be informed by the digital data the coach has viewed, as well as the expectation that the coach will continue viewing data in order to provide ongoing support. Assessments will be completed at 0, 12, 26, 40, and 52 weeks.

抽象的 在生活方式修改计划中，与干预主义者（例如，减肥教练）接触会产生 支持责任制，可以促进行为变化和体重减轻。维持强烈的意识 面对面干预接触结束后的支持性问责制有可能改善结果 在众所周知的艰难减肥期间。一种促进支持性的创新方式 问责制为参与者提供数字工具，这些工具可以客观地衡量体重，PA并跟踪食物 实时摄入量，从这些工具中自动且连续地从这些工具中获取数据，并 设计干预联系人的时间和内容，以便它们对共享数据响应。 尽管可以容易获得从传感器和基于Internet的应用程序中共享数据的工具，但是 在生活方式修改计划中，他们将其整合到干预联系人中的方式尚未 优化，研究尚未系统地评估数据共享对行为的影响。超重 和肥胖的参与者（n = 90）将从社区招募小RCT，以测试 生活方式修改干预措施的可行性，可接受性，功效和作用机制增强了 与数据共享。在该计划的第1-12周（即第一阶段）中，所有参与者将面对面参加12个每周12 面部，基于群体的行为治疗课程，以引起体重减轻。参与者将为 无线体重尺度，PA传感器和数字食品记录应用程序，并指示每天使用它们 自我监控目的。在第二阶段（第13-52周）中，参与者将被随机分配给标准 （LM）或增强版本的远程生活方式修改（LM+共享）。两种情况都不会面对面 第二阶段的面部干预接触；远程干预联系人将包括简短的电话和短信 参与者教练提供的消息。在这两种情况下的参与者每天将继续开处方 使用三种自我监控设备。在标准LM条件下，这些设备的数字数据不会 与教练直接分享；干预遭遇只会由频繁的，延迟的自我告知 参与者的报告（这是当前的长期肥胖护理标准），短信的时间将 被固定。在LM+共享中，数字工具将自动，连续地传输体重，PA和 食物记录数据给教练。在LM+共享中，支持责任制将通过三种方式增强：1） 教练查看数据后，参与者将收到自动警报，2）个性化文本的时间 教练的消息将对临床上值得注意的体重，PA，卡路里摄入量的变化有反应或使用 比例，PA传感器或食物记录工具以及3）文本消息和电话的内容将由 教练查看的数字数据以及教练将继续查看数据的期望 为了提供持续的支持。评估将在0、12、26、40和52周完成。
