Abstract
Suicide is the second leading cause of death for youth aged 10-24. Research informed prevention efforts have the opportunity to decrease risk for suicidal ideation and behavior before it is manifested. Indeed, there is a small body of research findings demonstrating both proximal and distal effects of preventive interventions delivered in childhood and adolescence on suicidal ideation and/or behavior. These efforts build off of other secondary analyses of prevention research that has demonstrated benefits for multiple types of youth outcomes. This supplement provides "proof of concept" that family-based preventive interventions aimed at reducing a number of risk factors for suicide (e.g., substance use, externalizing, and internalizing behavior) can prevent suicidal ideation and behaviors.
