Universal and selective preventive interventions targeting youth behavioral problems have shown crossover effects on suicide risk, the second leading cause of death among youth. However, the mechanisms that explain this long-term unanticipated benefit are understudied and unclear. The current study examines the crossover effects of PROSPER, a…

The programme was designed to increase the moderate to vigorous physical activity (PA) level at school among Lebanese children, aged…

Objective: Despite evidence-based interventions for the psychiatric disorders that often precede suicidality, suicide remains a leading cause of death among youth. There has been increased interest in whether preventive interventions targeting early risk factors lead to decreased distal risk for suicidal thoughts and behaviors (STB). We examined…

Bullying is a major health problem. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on self-reported bullying victimization and perpetration. No evaluations of this program have been conducted in Latin America. A cluster randomized controlled trial was conducted at socially…
