The Tailored Diet and Activity (ToDAy) study aims to build on the campaign by adding a digital intervention with the potential to provide wide-reaching, cost-effective weight management support.
The ToDAy study aims to build a tailored intervention using mobile technology to improve diet and physical activity behaviours in adults with overweight and obesity. The main objectives were to identify behavior change techniques for diet and physical activity (PA) change for weight loss and explore preferences for digital intervention features that would be effective in changing diet and PA behaviors.
This qualitative study uses the principles of a person-based approach to intervention development; the behavioral intervention technology framework; and the capability, opportunity, motivation, and behavior (COM-B) framework. Focus groups and telephone interviews were conducted with 56 adults in Western Australia. Open-ended questions and example intervention features were used to explore the usability and acceptability of the self-monitoring tools, knowledge about effective weight-loss strategies, and acceptability of tailored feedback. Findings from the focus groups and interviews were analyzed using thematic analysis.
Qualitative findings revealed an awareness of key public health messages but a lack of confidence in how to perform these behaviors to help manage their weight. A total of 4 major themes were identified and mapped to the domains of the COM-B framework: (1) misinformation, (2) environmental support, (3) social norms, and (4) confidence.
This study explores users' capability, opportunity, and motivation to perform the target behaviors for weight loss. The findings suggested that a digital weight management intervention using a mobile food record and activity trackers to inform tailored feedback may be acceptable and feasible. Participants expressed a preference for simple expert advice, digital self-monitoring tools, and visual feedback.

Tailored Diet and Activity（ToDAy）研究旨在通过添加数字干预措施来扩大范围并提供经济有效的体重管理支持，从而在此基础上进一步展开研究。
ToDAy 研究旨在利用移动技术构建定制干预措施，以改善超重和肥胖成年人的饮食和身体活动行为。主要目标是确定针对减肥的饮食和身体活动（PA）行为改变技术，并探索有效的数字干预功能偏好，以改变饮食和 PA 行为。
本定性研究采用基于个人的干预措施开发原则；行为干预技术框架；以及能力、机会、动机和行为（COM-B）框架。在西澳大利亚州对 56 名成年人进行了焦点小组和电话访谈。使用开放式问题和示例干预功能，探讨自我监测工具的可用性和可接受性、关于有效减肥策略的知识，以及定制反馈的可接受性。使用主题分析对焦点小组和访谈的结果进行了分析。
定性研究结果揭示了对主要公共卫生信息的认识，但对如何执行这些行为以帮助控制体重缺乏信心。共确定了 4 个主要主题，并映射到 COM-B 框架的各个领域：（1）错误信息，（2）环境支持，（3）社会规范，以及（4）信心。
本研究探讨了用户执行减肥目标行为的能力、机会和动机。研究结果表明，使用移动食物记录器和活动跟踪器来提供定制反馈的数字体重管理干预措施可能是可以接受且可行的。参与者表示更喜欢简单的专家建议、数字自我监测工具和可视化反馈。
