Health-promotion research over three decades: The social-ecological model and challenges in implementation of interventions

AIMS: This debate paper traces the development of innovative methods for undertaking health promotion research with a socialecological orientation, with a few examples drawn from 30 years of research on adolescent health promotion research at the University of Bergen. CONCLUSION: We aim to show how the social-ecological model is becoming more evident as a guide to research, using three cases that illustrate progress and potential. The first case is the Norwegian part of the European Network of Health Promoting Schools. The second case is a project just underway, The COMPLETE study, which is a community-led effort to promote students' mental health and create a good psychosocial learning environment. The third case is a developing idea for the next generation of social-ecological research on adolescent well-being, using an asset approach to foster social inclusion and sense of community in multiple settings.
