This paper describes a new way of monitoring the health status of Dutch adolescents in order to stimulate the development of health policies at school and local levels and providing individual feedback using modern technology. The project is called E-MOVO that stands for Electronic Monitor and Health Education, in which seven Regional Health Authorities and the University of Maastricht collaborate. In this project, adolescents completed an electronic questionnaire via the Internet which measured topics related to demographics, school, physical health, mental health, well-being, lifestyle, criminality and leisure time activities. These data were used for feedback at three levels. On the basis of their answers, adolescents received tailored feedback on lifestyle in a personal ‘E-MOVO score’, including links to relevant websites or other tailored information. The aggregated data were used to provide schools and municipalities with information on the health and well-being of their adolescent population. These data were used to encourage the development of health promoting policies and activities at both levels. This project was evaluated and is now adapted to implement at a national level.
