Canada's national task force on suicide suggests that people who mourn a suicide make up a group that is itself at risk. Literature shows that mourners of a suicide have a suicide rate that is nine times higher than average. While some authors suggest that this type of mourning is more intense and of a longer duration that for other types of mourning, other authors doubt this hypothesis. But what happens in reality? Is suicide mourning truly different from other types of mourning? Is it really a unique mourning experience? These are some of the questions the authors of this article have attempted to answer. Following an in-depth review of studies on the matter, the authors conclude that the mourning of a suicide encompasses certain characteristics that manifest themselves especially in more vulnerable people.
