Abstract
BackgroundAdoption 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. ObjectiveThe 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.MethodsA 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.ResultsThe randomized controlled trial started in January 2018. As participants can start at different moments, we aim to finish all testing by July 2019.ConclusionsThis 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.International Registered Report Identifier (IRRID)DERR1-10.2196/12413
Highlights
Diabetes is associated with various health problems including kidney failure, retinopathy, and cardiovascular disease [1]
Several proposals have been formulated to better design and implement Electronic health (eHealth) and mobile health (mHealth) interventions for adults with type 2 diabetes
This study describes the protocol for a randomized controlled trial examining how a self-regulation–based eHealth and mHealth intervention (“MyPlan 2.0”) targeting sedentary behavior and physical activity influences the behavior-change process of adults with type 2 diabetes
Summary
Diabetes is associated with various health problems including kidney failure, retinopathy, and cardiovascular disease [1]. Cost-effective approaches that help adults with type 2 diabetes in increasing their physical activity and reducing their sedentary behavior are needed. Research about the effectiveness of online interventions targeting adults with type 2 diabetes reveals mixed results [5,6,7]. A useful perspective may well be the self-regulation framework, which focuses on both preintentional (such as increasing knowledge) and postintentional (such as action and coping planning) processes of behavior change [10]. This study describes the protocol for a randomized controlled trial examining how a self-regulation–based eHealth and mHealth intervention (“MyPlan 2.0”) targeting sedentary behavior and physical activity influences the behavior-change process of adults with type 2 diabetes. The needs of adults with type 2 diabetes were taken into account, as they were actively involved in the development of the program [15,16].
