文献中讨论了两种常见的自杀群类型：粗略地，这些可以分为质量簇和点簇。大规模集群与媒体有关，但其证据却是模棱两可的；点簇是局部现象，而且这些现象似乎确实发生了。传染在概念上尚未得到充分发展，也没有在经验上得到很好的支持来解释自杀集群。对于自杀有时会聚集的另一种解释是：易受自杀影响的人可能在任何明显的自杀刺激发生之前就聚集在一起，当他们经历严重的负面事件时，包括但不限于聚集中一名成员的自杀行为，聚集中的所有成员的自杀风险都会增加（这种风险可以通过良好的社会支持来抵消）。
Two general types of suicide cluster have been discussed in the literature; roughly, these can be classified as mass clusters and point clusters. Mass clusters are media related, and the evidence for them is equivocal; point clusters are local phenomena, and these do appear to occur. Contagion has not been conceptually well developed nor empirically well supported as an explanation for suicide clusters. An alternative explanation for why suicides sometimes cluster is articulated: People who are vulnerable to suicide may cluster well before the occurrence of any overt suicidal stimulus, and when they experience severe negative events, including but not limited to the suicidal behavior of one member of the cluster, al members of the cluster are at increased risk for suicidality (a risk that may be offset by good social support).
