Suicide clusters: introducing a novel type of categorization

A suicide cluster within a given community may be defined as a group of suicides or suicide attempts, or both, that happen closer together in time and space than would generally be expected. However, since the perception of clustering may itself be a risk factor for suicide, suicide clusters differ almost from all other event clusters. The aim of this article, therefore, is to discuss the unique pattern of suicide cluster and introduce a novel type of categorization taking into account varieties of studies, which investigate suicide clusters within diverse settings. This article concludes with challenging areas in suicide cluster studies and emphasizing that each community must deal rapidly and appropriately with any perceived suicide clusters.
