This paper is an analysis of the concept of empowerment and its use in nursing practice, education, research and health promotion. The paper adopts an eclectic approach to concept analysis, incorporating the methods advocated by Walker & Avant and Rodgers. The concept is analysed and a theoretical definition given. Defining attributes, related concepts, antecedents and consequences of empowerment are proposed and a model case presented. The analysis demonstrates that empowerment is: a helping process; a partnership valuing self and others; mutual decision making; and freedom to make choices and accept responsibility. Implications for practice conclude the paper.
