As high amounts of occupational sitting have been associated with negative health consequences, designing workplace interventions to reduce sedentary behaviour (SB) is of public health interest. Digital technology may serve as a cost-effective and scalable platform to deliver such an intervention. This study describes the iterative development of a theory-based, digital behaviour change intervention to reduce occupational SB.
The behaviour change wheel and The Behaviour Change Technique Taxonomy were used to guide the intervention design process and form a basis for selecting the intervention components. The development process consisted of four phases: phase 1 - preliminary research, phase 2 - consensus workshops, phase 3 - white boarding and phase 4 - usability testing.
The process led to the development and refinement of a smartphone application - Worktivity. The core component was self-monitoring and feedback of SB at work, complemented by additional features focusing on goal setting, prompts and reminders to break up prolonged periods of sitting, and educational facts and tips. Key features of the app included simple data entry and personalisation based on each individual's self-reported sitting time. Results from the 'think-aloud' interviews (=5) suggest Worktivity was well accepted and that users were positive about its features.
This study led to the development of Worktivity, a theory-based and user-informed mobile app intervention to reduce occupational SB. It is the first app of its kind developed with the primary aim of reducing occupational SB using digital self-monitoring. This paper provides a template to guide others in the development and evaluation of technology-supported behaviour change interventions.
由于大量的职业久坐与负面健康后果相关，设计工作场所干预措施以减少久坐行为（SB）具有公共卫生意义。数字技术可以作为一个具有成本效益且可扩展的平台来实施此类干预。本研究描述了一种基于理论的数字行为改变干预措施的迭代开发过程，以减少职业性久坐行为。
行为改变轮和行为改变技术分类法被用于指导干预设计过程，并为选择干预组件提供基础。开发过程包括四个阶段：第1阶段——初步研究，第2阶段——共识研讨会，第3阶段——白板讨论，第4阶段——可用性测试。
该过程促成了一款智能手机应用程序——Worktivity的开发和完善。其核心组件是对工作中的久坐行为进行自我监测和反馈，并辅以专注于目标设定、提醒打破长时间久坐的提示和提醒，以及教育性事实和小贴士等附加功能。该应用程序的关键特性包括简单的数据输入以及基于每个人自我报告的久坐时间进行个性化设置。“出声思考”访谈（n = 5）的结果表明，Worktivity广受好评，用户对其功能持积极态度。
本研究促成了Worktivity的开发，这是一款基于理论且以用户为导向的移动应用程序干预措施，旨在减少职业性久坐行为。它是同类应用程序中首个以通过数字自我监测减少职业性久坐行为为主要目标而开发的应用。本文提供了一个模板，以指导其他人开展技术支持的行为改变干预措施的开发和评估。
