"EspaiJove.net"- a school-based intervention programme to promote mental health and eradicate stigma in the adolescent population: study protocol for a cluster randomised controlled trial.

Background: One half of adults who develop any mental disorder do so during adolescence. Previous literature showed that Mental Health Literacy (MHL) interventions impact mental health knowledge, reduce the associated stigma, and promote help-seeking among the adolescent population. However, evidence for the effectiveness and cost-effectiveness of these programmes remains inconclusive.
