Abstract
As nursing continues to develop as a professional discipline, it is important for nurses to have a central question to guide their research. Since the 1800s, nursing practice and research have covered a wide scope in cooperation with other disciplines. This wide area of nursing practice and research has led to the proposal that the central question be: How can the well‐being of a person, family, community, or population be improved? The proposed question must remain flexible and open to revision because nurses will continue to adapt to the changing needs of their patients and populations and to their complex and evolving work environments.
