Apparent random acts of violence viewed in the aggregate appear to occur in fairly exacting temporal patterns. This is true of rape, street assaults, and domestic violence, among other acts of violence. Patient assaults on staff as acts of violence should also follow a temporal pattern. This twenty-year retrospective study of assaultive psychiatric patients in one public sector examined the temporal pattern of such assaults. Inpatient assaults were more likely to occur in the summer in the middle ten days of the month, during the first shift at mealtimes. In community settings, assaults were more likely in winter during the first ten days of the month, and on the first shift at noon time. The possible reasons for these time patterns, their possible biological roots, and their implications for emergency services personnel and health care providers were discussed.
从总体上看，明显随意的暴力行为似乎呈现出相当严格的时间模式。强奸、街头袭击和家庭暴力等暴力行为皆是如此。患者对医护人员的袭击作为暴力行为也应遵循一种时间模式。这项针对一个公共部门中具有攻击性的精神病患者的二十年回顾性研究，考察了此类袭击的时间模式。住院患者的袭击更有可能发生在夏季月中十天，且在就餐时间的第一个班次。在社区环境中，袭击更有可能发生在冬季月初十天，以及中午的第一个班次。文中讨论了这些时间模式的可能原因、它们可能的生物学根源，以及它们对急救服务人员和医疗保健提供者的影响。
