健康是護理專業關注的焦點，是護理知識的核心。健康概念的認識，影響護理照護本質內涵的提供。長期以來，國內護理領域裡對於健康此一多層面、複雜、及多元的重要概念定義，尚無統整概念。故本文配合Walker與Avent（1995）所提概念分析法，針對過去眾多健康相關文獻進行回顧，整理出定義性特徵：健康是一個具有主觀性、個別性、客觀性、文化性、多面向性、動態性、主控性、他控性、調整性與發展性的過程與結果。希冀本文對健康概念的釐清，提供護理臨床實務、理論測試與研究進行的理論參考。

　　　　　Health, the reason for the nursing profession's existence, is the core purpose behind all nursing knowledge. The nature of nursing care is determined by the appreciation of health concepts. For a long time, the multidimensional, complex and changing characteristics of health have not been completely analyzed in Taiwan. The purpose of this article is to define health in terms of the concept analysis method of Walker and Avent (1995). The results show that: health is a process and outcome that involves subjectivity, individuality, objectivity, culture, dynamics, self-control, external control, changeability, and development. The clarification of health concepts will be important and useful to the theoretical basis of nursing practice, to the development of both theory and research, and especially for the development of instruments.
