This review assessed the evidence of the effects of the Northern Ireland conflict on mental health & well-being, with special reference to suicide. Three main questions are considered: 1) to what extent has the conflict contributed to & exacerbated, the social factors & circumstances known to be associated with poor mental health; 2) what research is there that identifies particular neighbourhoods & communities as high risk in terms of poor mental health & suicide; & 3) what is known about the prevalence of suicide risk factors among individuals who were in the frontline of violence?
