Preventive interventions for youth suicide: a risk factor-based approach

Area of Science:

• Public Health
• Psychiatry
• Child and Adolescent Health

Background:

• Youth suicide remains a significant public health concern requiring effective prevention strategies.
• Current knowledge of suicide risk factors informs the development of interventions.
• A comprehensive review is needed to evaluate existing strategies and identify research gaps.

Purpose of the Study:

• To categorize youth suicide intervention strategies based on risk.
• To identify critical areas for future research in suicide prevention.
• To establish an evidence base for identifying cost-effective preventive interventions for youth suicide.

Main Methods:

• Review of existing literature on suicide prevention strategies.
• Consideration of interventions across clinical to population-based approaches.
• Analysis within five key risk factor domains: individual, family, community, school, and peer.

Main Results:

• Limited evidence exists for interventions directly targeting depression and suicidal behavior.
• Effective indicated, selective, and universal interventions are available for key risk factors.
• Traditional approaches like school-based education and hotlines show limited evidence of efficacy.

Conclusions:

• Australian youth suicide prevention often relies on traditional methods, including clinical interventions and access restriction.
• Program development and research evaluation for many crucial suicide risk and protective factors have been overlooked.
• There is a need to shift towards evidence-based, targeted interventions and further research.
