Factors associated with aggression among psychiatric in-patients are still poorly understood. Inconsistent published findings are partly attributable to methodological problems. Much previous research has been under taken in specialist settings, where conditions are likely to differ from those in acute admission wards.
Levels of aggression were ascertained weekly by staff report, using a reliable measure, for every patient on five acute admission wards and one locked intensive care ward at two hospitals prospectively over a five-month period.
Levels of aggression varied considerably among the admission wards. Aggression was more common on the locked ward and among younger patients. Factors associated with aggression changed with time since admission (seldom examined in previous studies). Complex associations were found with gender, ethnic group and diagnosis.
Some of the findings might be explicable by differences in ward environment, and staff-patient inter-actions. Further investigation into these is warranted.
与精神科住院患者攻击行为相关的因素仍未得到充分理解。已发表研究结果的不一致部分归因于方法学问题。此前的许多研究是在专科环境中进行的，那里的情况可能与急性入院病房不同。
在为期五个月的时间里，前瞻性地对两家医院的五个急性入院病房和一个封闭式重症监护病房的每位患者，通过工作人员报告，使用可靠的测量方法每周确定攻击行为水平。
各入院病房的攻击行为水平差异很大。攻击行为在封闭式病房和年轻患者中更为常见。与攻击行为相关的因素随入院时间而变化（此前研究很少对此进行考察）。发现与性别、种族和诊断存在复杂关联。
某些研究结果或许可以通过病房环境及医护人员与患者互动的差异来解释。有必要对此进行进一步调查。
