Ireland’s national strategy to reduce suicide, Connecting for Life, ended in 2024 and has entered its evaluation stage. To support the development of Ireland’s next suicide reduction strategy, the Department of Health commissioned the National Suicide Research Foundation (NSRF) to conduct an evidence synthesis on the evidence base for suicide prevention with regards to risk and protective factors and interventions for suicide.

The aim of this report is to synthesise evidence on interventions for suicide prevention, and risk and protective factors for suicide and self-harm. The review has prioritised recent (within the past ten years) and high-quality reviews published on these topics and research relevant to the Irish context.
