22、的规律性认识。2美学知识(Esthetics)：即护理艺术或护理行为方 面的知识。3个人知识(Intuition)：即通过个人的直感而获取服务对象的认识。4科学知识(Science)：即通过科学实验的方法所获取的护理学知识。1南丁格尔时代2哥伦比亚大学学派时代（二十世纪50 年代）3耶鲁大学学派时代二十世纪60年代4二十世纪70年代5二十世纪80年代到目前1、南丁格尔时代（Nightingale)2、医学模式阶段(Medical model)3、借用阶段(borrowed theories)4、独特理论阶段(Unique theories)妥瑞斯（Torres，1990）理论必须具有以下几个基

23、本的特征：1理论能够将概念以特殊的方式联系起来，从而提供一个全新的观察事物的方法或角度。2护理理论必须具有一定的逻辑性。3理论必须简单易懂，并容易推广应用。4理论可以作为假设的基础而经受检验。5通过对理论的实践及研究，能够增加 护理学科的知识。6必须对实践有指导作用。7必须与其它已证实的理论及规律一致。1按照护理理论的抽象程度及其对实践的指导意义(scope of the theory)，可以将护理理论分为以下三类：Grand theory Middle range theory Micro theory or partial theoryGrand TheoriesuBroadest in
