- planned startdate 10-jan-2016
- planned closingdate31-dec-2016
- Target number of participants150
- InterventionsA2G intervention will be delivered through an web-based app, adjusted for the intervention condition.
The A2G intervention including tailoring based on the computational model will be compared with: (a) the A2G intervention with random coaching messages, (b) the Fitbit condition, where participants will only receive a Fitbit device and access to the Fitbit website, (c) the control group, where the participants will solely receive general information about physical activity through the A2G app.
- Primary outcomelevels of physical activity (moderate, vigorous, moderate-vigorous); minutes of moderate-vigorous per week after 3 months
- Secondary outcomenumber of stairs taken per week, weekly minutes of sports participation, weekly minutes of active transport levels of self-efficacy, outcome expectation, social norm, intention, self-regulation after 3 months

- Brief summaryThe aim of the Activ2Gether (A2G) app, is to contribute to empowering young adults to be and remain physically active. A2G makes use of personalized, real-time and context specific feedback and an activity tracker (Fitbit). A2G uniquely combines behavior change techniques with a model-based reasoning system in order to provide context specific coaching messages. The messages are based on proven behavior change techniques (e.g., self-monitoring, goal-setting, social-comparison) and are framed in an autonomy-supportive style. Furthermore, social network techniques will be used to influence beliefs and subsequent behavior.
