Middle-Range Theory of the Adapting Foster Family: Mathematical Modeling in Nursing Science

Nursing science has the epistemic advantage of using nursing practice for developing middle-range theories to bridge abstract ideas with clinical research. The theory of the adapting foster family draws upon extant theories of both family systems theory and transition theory while integrating experiences from nursing practice. The new theory provides a framework for improving outcomes for children in foster care through greater placement stability. Theory development incorporated a literature review, concept exploration, statement synthesis, and mathematical theory modeling to elucidate the interaction between concepts and provide insight to the unique fostering experience.
