There is a clear need for evidence-based approaches to promote mental health and prevent violence among youth. These programs need to be flexible enough to be implemented in diverse settings. Ideally, they would also address multiple outcomes at once. We know that there is a significant overlap among violence, substance misuse, and unhealthy sexual behaviour (i.e., the adolescent risk triad). These problem behaviours are linked in several ways: they co-occur, they share risk factors, and they frequently emerge within the context of dating and peer relationships. More recently, researchers have identified mental health as an issue that overlays all of these other issues.
