- Scientific TitleEvaluation of a universal school-based depression prevention program for adolescents.
- hypothesisThe (long term) effectiveness of a school-based universal depression prevention program (“Op Volle Kracht”) will be tested in a Dutch sample of adolescents (aged 12-14 years). It is expected that adolescents who receive the intervention will show lower levels of depressive symptoms during the 2 years following the intervention, compared to the control group. Moreover, adolescents in the experimental group are hypothesized to show increases in positive outcomes as well (secondary outcomes) during the 2 years after the intervention, compared to adolescents in the control group.
