Kracht van Kracht is a program with a focus on the promotion of physical activity of youth. It is used on secondary schools. During physical education there is focus on exertion, during mentor lessons there’s special attention on motivation to move. This motivational intervention is supported by a SOTO based website. The participants have to perform monthly assignments over a period of two years, consisting of several online questionnaires and application forms. In total there are over a thousand students involved in this project.

For this project we’ve build a taylor made front-end for SOTO. With SOTO one can easily perform webbased longitudional studies over a prolonged time and addressing a multitude of participants.
