Suicide is a major public health issue of global concern. It is the leading cause of death in young Irish men, marking suicide and suicidal behaviour as important topics for clinical epidemiology and public health research. Ireland has a statutory obligation from the “Reach Out” policy document to “systematically plan research into suicidal behaviour to address deficits in our knowledge” (pp. 50). Suicide is undoubtedly a complex phenomenon and therefore one which requires advanced methods of investigation and innovative approaches to research the factors underpinning suicide in modern Ireland, the development and evaluation of prevention strategies and the informing of evidence-based policy.
