Active2Gether

The 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.

Active2Gether effectively increases levels of physical activity in young adults.

3 time points:

baseline (T1): (intake questionnaire & Actigraph)

1.5 months follow-up (T2): intake questionnaire
and evaluation at 3-month follow- up (T3): Intake questionnaire & Actigraph

A2G 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.

a) The A2G intervention with tailored coaching messages, social comparison and self-monitoring
b) The A2G intervention without coaching messages and only social comparison and self-monitoring
c) The Fitbit group with a Fitbit and the Fitbit app
