The mid-range theory of self-transcendence by Pamela G. Reeds was developed in 1990 (Reed, 1991). It was largely based on the approach of deductive reformulation. The deductive reformulation strategy emanated from Pamela’s professors during her time at Wayne State University. It involves the use of knowledge acquired from the non-nursing theory that is redrawn deductively from a nursing conceptual model, and the theorist used life span developmental psychology for adult social-cognitive and transpersonal development to reformulate this mid-range theory by applying the principles of Martha E. Roger’s conceptual system that describes the unitary human being (Reed, 1991).
