A web-based approach to adolescent mental health: Randomized controlled trial of a brief Positive Psychology intervention

The findings have important implications for future efforts in the prevention of mental health problems. In particular, they provide more information on how to deliver brief online, multi-component Positive Psychology interventions for healthy young people. As the results indicated good acceptance and adherence in our adolescent sample but no differential effects, we encourage further mixed methods research evaluating the perceived usefulness and person-activity-fit to understand the optimal methodology for the delivery of Positive Psychology interventions to have beneficial effects.
