Internet-based Program for Prevention and Early Intervention of Adolescent Depression

Background: Depression is prevalent and can have devastating effects on the life of adolescents. Computerized intervention programs for depression have shown positive results. There is less evidence in prevention and early treatment for depression in Latin American adolescents. Purpose: The purpose of this study is to determine whether a stepped internet-based program is effective to prevent and early intervene depression in adolescents attending 9th to 11th grade in eight schools in Santiago, Chile. Study design: A two-arm cluster-randomized clinical trial will be carried out with approximately 600 adolescents.
