Adoption of an active lifestyle plays an important role in the management of type 2 diabetes. Online interventions targeting lifestyle changes in adults with type 2 diabetes have provided mixed results. Previous research highlights the importance of creating theory-based interventions adapted to the population's specific needs. The online intervention "MyPlan 2.0" targets physical activity and sedentary behavior in adults with type 2 diabetes. This intervention is grounded in the self-regulation framework and, by incorporating the feedback of users with type 2 diabetes, iteratively adapted to its target population.
The aim of this paper is to thoroughly describe "MyPlan 2.0" and the study protocol that will be used to test the effectiveness of this intervention to alter patients' levels of physical activity and sedentary behavior.
A two-arm superiority randomized controlled trial will be performed. Physical activity and sedentary behavior will be measured using accelerometers and questionnaires. Furthermore, using questionnaires and diaries, patients' stressors and personal determinants for change will be explored in depth. To evaluate the primary outcomes of the intervention, multilevel analyses will be conducted.
The randomized controlled trial started in January 2018. As participants can start at different moments, we aim to finish all testing by July 2019.
This study will increase our understanding about whether and how a theory-based online intervention can help adults with type 2 diabetes increase their level of physical activity and decrease their sedentary time.

采取积极的生活方式在2型糖尿病的管理中起着重要作用。针对2型糖尿病成年人生活方式改变的在线干预取得了喜忧参半的结果。先前的研究强调了创建适应人群特定需求的基于理论的干预措施的重要性。在线干预“MyPlan 2.0”针对2型糖尿病成年人的身体活动和久坐行为。该干预基于自我调节框架，并通过纳入2型糖尿病患者的反馈，反复调整以适应其目标人群。
本文旨在全面描述“MyPlan 2.0”以及将用于测试该干预措施改变患者身体活动水平和久坐行为有效性的研究方案。
将进行一项双臂优势随机对照试验。将使用加速度计和问卷来测量身体活动和久坐行为。此外，将通过问卷和日记深入探究患者的压力源和改变的个人决定因素。为了评估干预的主要结果，将进行多层次分析。
随机对照试验于2018年1月开始。由于参与者可以在不同时间开始，我们的目标是在2019年7月前完成所有测试。
本研究将增进我们对于基于理论的在线干预是否以及如何帮助2型糖尿病成年人提高身体活动水平和减少久坐时间的理解。
