Toward a nursing theory of self-transcendence: deductive reformulation using developmental theories.

The purpose of this article is to explicate the development of an emerging middle-range nursing theory of self-transcendence. The process of developing the theory was based largely on the method of "deductive reformulation." Using this strategy, theoretic knowledge derived from life span developmental psychology was reformulated based on Rogers' conceptual system. Clinical experience and empirical investigations were also important in the theory development process. The theory of self-transcendence is potentially useful for application in various nursing settings where clients' well-being may be compromised by end-of-life issues.
