A scoping review examined multi-component services and programs aimed at preventing suicide and self-harm among adolescents and young adults in Australia, specifically those aged 12-25. Researchers conducted a systematic search across multiple databases and identified relevant publications from 2014 to 2024, analyzing data through narrative synthesis. The review included six journal articles and six grey literature reports, highlighting five distinct multi-component initiatives. Findings revealed a limited number of strategies, with most focusing on suicide prevention rather than self-harm alone. Programs varied in delivery methods: three were community-based, one was web-based, and one was school-based. Common elements included psychoeducational materials, peer support, and professional counseling. The review noted significant differences in evaluation methods across initiatives. While some programs showed promising outcomes, the lack of comprehensive, long-term evaluations hampers a full understanding of their effectiveness. Additionally, the absence of programs exclusively targeting self-harm indicates a critical gap. The study underscores the necessity for targeted, evidence-based strategies that differentiate between self-harm with suicidal intent and non-suicidal self-harm.
