A scoping review of multi-component suicide and self-harm prevention programs for young people in Australia

This scoping review aimed to describe current multi-component services and programs with the primary purpose of preventing suicide and self-harming behaviours among adolescents and young adults aged 12-25 years in Australia and summarise evaluations of these initiatives.

A systematic search of Embase, PsycINFO, PubMed, Scopus, and grey literature was conducted to identify relevant publications from 2014 to 2024. Data on identified services and programs were then analysed using a narrative synthesis approach. A quality assessment of evidence was also employed.

The review included six journal articles and six grey literature reports, detailing five different multi-component services and programs. Findings indicated relatively few existing multi-component strategies, with most targeting suicide or suicide and self-harm prevention. No identified multi-component programs focused solely on preventing self-harm. Three programs were delivered in community-based settings, one was web-based, and one was school-based. Common program components included psychoeducational materials/interventions, peer-to-peer support, and professional support/counselling. There was significant variation in how initiatives were evaluated.

The review suggests that there are few multi-component strategies for preventing suicide and self-harm among young Australians. Most of those identified were only introduced within the past 6 years, leaving little opportunity for comprehensive, long-term evaluations. Although available evidence indicates promising results, the scarcity of completed evaluations limits understanding of their overall effectiveness. The absence of multi-component programs specifically addressing self-harm highlights a key gap, emphasising the need for targeted, evidence-based prevention strategies that distinguish between self-harm with suicidal intent and non-suicidal self-harm.
