中文摘要：

对具有即时性危险的精神障碍者实行强制入院是维护社会安全所采取的一项必要手段,也是精神卫生立法的难题之一。世界各国各地区近年相继对其强制入院的实质和程序要件进行修订与完善。虽然各国各地区对强制入院的法律规制因制度与文化不同而存在差异,但也存在共通性。我国2009年《精神卫生法》（草案）》和2011年《精神卫生法（征求意见稿）》中的强制入院制度存在实质要件模糊、程序要件缺失等问题,因而需要依据强制入院共通的基本原则,结合我国的实际,补充和完善强制入院的实质与程序要件,以实现精神障碍者权益保护和他人权益、社会整体利益保障之间的平衡。

英文摘要：

The involuntary admission in ＇Mental Health Act＇ for the mentally ill persons who are serious likelihood of immediate danger is a necessary means of maintaining society security and a difficult issue in mental health legislation. Countries and regions all over the world have revised and improved their essential and procedural elements for involuntary admission. Because of the differences in systems and cultures among different countries, the involuntary admission systems in many coun- tries are with both difference and commonality. The essential elements are fuzzy and procedural elements are inadequate for involuntary admission system in two drafts of ＇Mental Health Act＇ in China. So we should complement and improve the essential and procedural elements for our involuntary admission system for the mentally incapacitated according to the common basic principles of the involuntary admission system, by drawing upon the advanced theory in ＂Mental Health Act＂ in other countries and combining with our China＇ s reality in order to achieve the balance between protecting the rights of the mental disorders and protecting the social interests.
