Objective: The aim of this study was to evaluate a school-based adolescent health promotion programme with focus on well-being related to stress.

Study design: Interventional and evaluative with tests before and after the intervention. The study was performed in two secondary schools in a town on the west coast of Sweden.

Methods: A health promotion programme comprising massage and mental training was implemented for a single academic year in one school (intervention school, 153 participants) in order to strengthen and maintain well-being. No intervention was implemented in the other school (non-intervention school, 287 participants). A questionnaire was developed and tested, resulting in 23 items distributed across the following six areas: self-reliance; leisure time; being an outsider; general and home satisfaction; school satisfaction; and school environment.

Results: A pre- and postintervention comparison of the six areas was made within each school. In the intervention school, the boys maintained a very good or good sense of well-being related to stress in all six areas, while the girls’ sense of well-being was maintained in five areas and deteriorated in one area. In the non-intervention school, the boys maintained a very good or good sense of well-being related to stress in four areas and deteriorated in two areas, while the girls’ sense of well-being was maintained in two areas and deteriorated in four areas.

Conclusion: Massage and mental training helped to maintain adolescents’ very good or good sense of well-being related to stress. A questionnaire with acceptable validity and reliability was developed and tested in order to evaluate the health promotional approach. However, there is a need for further study to develop both the intervention and the questionnaire for young people.
