Adolescence is a critical period for the onset of mental health challenges. This study evaluated the effectiveness of OurFutures Mental Health, a school-based intervention designed to improve mental health knowledge and prevent symptoms of depression and anxiety among young people.

A two-arm cluster-randomised controlled trial was conducted between 2023 and 2024. Findings suggest that OurFutures Mental Health is a promising intervention, with evidence of improved mental health knowledge and short-term reductions in anxiety symptoms among adolescents.
