背景。自杀未遂集群发生的程度是一个重要问题，它是对当前关于已完成自杀集群的现有研究的补充。然而，关于自杀未遂集群的系统研究却很少。本研究探讨了自杀未遂聚集的程度和性质。方法。对新西兰所有医院的全国数据进行了检查，这些数据是从新西兰卫生统计服务处获得的 1988-1990 年期间自杀未遂事件的聚集情况。采用Scan统计量和Knox程序分别检验簇在时间和时空上的显着性。结果。分析表明，显着的时间聚集发生在较年轻的年龄组中，特别是 15-19 岁和 20-24 岁的人群中。这一结果无法用入学人数的季节性变化来解释。时空集群的年龄特异性出现，表现出与美国报道的自杀完成者相似的模式。结论。研究结果表明，拟自杀和完成自杀的聚集存在类似的潜在机制，并为自杀行为传染的存在提供了支持。讨论了预防的影响。
Background. The extent to which clusters of attempted suicides occur is a significant problem that is complementary to the current available research on the clustering of completed suicide. However, little systematic research on clusters of attempted suicides exists. The present study examines the extent and nature of clustering of suicide attempts.Method. The occurrence of clustering of attempted suicide was examined in nationwide data for all New Zealand hospitals, obtained from the New Zealand Health Statistics Services for the years 1988-1990. The Scan statistic and Knox procedure were employed for testing the significance of clusters in time and time-space, respectively.Results. The analyses indicated that significant time clustering occurred in younger age groups, specifically among 15-19 and 20-24 year olds. The results could not be accounted for by seasonal variations in admissions. Age specificity of time-space clusters emerged, exhibiting a similar pattern to that reported for completed suicides in the US.Conclusions. The results suggest a similar underlying mechanism for the clustering of parasuicide and completed suicides and provide support for the existence of contagion of suicidal behaviour. The implications for prevention are discussed.
