Wikipedia
A postvention is an intervention conducted after a suicide, largely taking the form of support for the bereaved (family, friends, professionals and peers). Family and friends of the suicide victim may be at increased risk of suicide themselves. Postvention is a term that was first coined by Shneidman (1972), which he used to describe "appropriate and helpful acts that come after a dire event." In Schneidman's view, "the largest public health problem is neither the prevention of suicide nor the management of suicide attempts, but the alleviation of the effects of stress in the survivors whose lives are forever altered." Postvention is a process that has the objective of alleviating the effects of this stress and helping survivors to cope with the loss they have just experienced.
The aim is to support and debrief those affected; and reduce the possibility of copycat suicide. Interventions recognize that those bereaved by suicide may be vulnerable to suicidal behaviour themselves and may develop complicated grief reactions.
Postvention includes procedures to alleviate the distress of suicidally bereaved individuals, reduce the risk of imitative suicidal behavior, and promote the healthy recovery of the affected community. Postvention can also take many forms depending on the situation in which the suicide takes place. Schools and colleges may include postvention strategies in overall crisis plans. These strategies are designed to prevent suicide clusters and to help students cope with the emotions of loss that follow the suicide of a friend. Individual and group counseling may be offered for survivors (people affected by the suicide of an individual).
