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 在生活方式改变计划中，与干预专家（例如减肥教练）的接触会产生一种 支持性责任可以促进行为改变和减肥。保持强烈的意识 面对面干预接触结束后的支持性问责有可能改善结果 在众所周知的艰难的减肥维持期。一种促进支持的创新方式 问责制为参与者提供客观测量体重和 PA 并跟踪食物的数字工具 实时摄入，使这些工具中的数据自动持续地提供给教练，以及 设计干预联系的时间和内容，以便他们对共享数据做出响应。 尽管允许传感器和基于互联网的应用程序共享数据的工具很容易获得， 将他们纳入生活方式改变计划的干预接触中的方式尚未确定 优化，研究尚未系统评估数据共享对行为的影响。超重 将从社区招募肥胖参与者（n = 90）进行小型随机对照试验，以测试 生活方式改变干预措施的可行性、可接受性、有效性和作用机制得到增强 与数据共享。在该计划的第 1-12 周（即第一阶段），所有参与者将每周参加 12 场面对面的会议 面部、基于团体的行为治疗课程以诱导减肥。参与者将获得一个 无线体重秤、PA 传感器和数字食物记录应用程序，并指导如何日常使​​用它们 自我监控的目的。在第二阶段（第 13-52 周），参与者将被随机分配到标准组 (LM) 或远程生活方式修改的增强版 (LM+SHARE)。这两种情况都不会面对面 在第二阶段面临干预接触；远程干预联系将包括简短的电话和短信 参与者教练提供的消息。患有这两种情况的参与者将每天继续服用处方 使用三个自我监控设备。在标准 LM 条件下，来自这些设备的数字数据不会 直接与教练分享；干预遭遇只能通过不频繁的、延迟的自我干预来获知。 参与者的报告（这是长期肥胖护理的现行标准）和短信的时间将 被修复。在LM+SHARE中，数字工具将自动连续传输体重、PA和 向教练提供食物记录数据。在 LM+SHARE 中，支持性问责制将从三个方面得到加强：1) 教练查看数据后，参与者将收到自动提醒，2) 个性化文本的时间安排 来自教练的信息将对体重、PA、卡路里摄入量或使用的临床显着变化做出反应 体重秤、PA传感器或食物记录工具，以及3）短信和电话的内容将由 教练查看过的数字数据，以及教练将继续查看数据的期望 以便提供持续的支持。评估将在第 0、12、26、40 和 52 周时完成。
