Background
Adolescent death by suicide is an emergent health crisis in the United States of America. Although many suicide prevention programs have been created to address suicide in this population, rates continue to increase. Online interventions can disseminate treatments world-wide and reach large numbers of users. This paper examines the effects of CATCH-IT, an Internet-based depression prevention intervention on risk factors for suicide (i.e., suicidal ideation, hopelessness, low self-esteem and social isolation).
