Identifying the Effect and Working Mechanisms of MyPlan 2.0 in Adults With Type 2 Diabetes

A Randomized Controlled Trial to Identify the Effect and the Working Mechanisms of MyPlan 2.0, a Self-regulation-based e- and mHealth Intervention Targeting Physical Activity and Sedentary Behaviour, in Adults With Type 2 Diabetes.

The aim of this study is to investigate whether and how 'MyPlan 2.0' helps adults with type 2 diabetes to be more physically active or less sedentary. Two groups will be created, an intervention group and a waiting-list control group.

The aim of this study is to investigate whether and how 'MyPlan 2.0' helps adults with type 2 diabetes to be more physically active or less sedentary. Two groups will be created, an intervention group and a waiting-list control group. Both groups will be tested during three testing waves: pretest, posttest and follow-up test. Only the intervention group will be given acces to 'MyPlan 2.0'. 'MyPlan 2.0' consists of a website and mobile application targeting physical activity and sedentary behaviour. The intervention has a duration of five weeks.

Participants will not receive the e- and mHealth intervention 'MyPlan 2.0', but will be given access to the intervention after all testing phases.

MyPlan 2.0 consists of five sessions. During these five sessions the following behaviour change techniques are used to motivate users to be more physically active or to sit less: exploring risk perceptions and perceived benefits, exploring social support, providing feedback, action planning, coping planning and monitoring.

Change in amount of total, light and moderate-to-vigorous physical activity, measured via accelerometers

Change in amount of total, light and moderate-to-vigorous physical activity, measured via the International Physical Activity Questionnaire (IPAQ)

Change in amount of total sitting time, measured via the LASA sedentary behaviour self-report questionnaire

Change in amount of self-efficacy to change behaviour, measured via 3 validated items (questionnaire)

Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months)
