Description
Summary:A paucity of studies exists that report on the description and testing of school-based interventions set out to promote mental well-being among adolescents, particularly in a Swedish context. The aim of this paper is to describe a new strength-based intervention designed using the core elements of solution-focused brief therapy for coaching within a normative frame of mental well-being. The Solution-focused Intervention for Mental health (SIM) is a nine-week, classroom-based, group intervention that has been developed to be both feasible and effective in addressing the current public health challenge concerning adolescent mental health. The intervention is described in accordance with guidelines for group-based behaviour change interventions. The results of three subsequent studies are presented and they support the intervention's feasibility. These studies demonstrate improvements in student participation, session attendance and ratings, as well as in a mental well-being outcome. The first two studies show small effect sizes and the third shows a medium effect size, thereby further substantiating the efficacy of implementing SIM in upper secondary schools. The program is now ready to be evaluated in a forthcoming randomized controlled trial.
