Johnson (redirected from Johnson, Michael)

Johnson, Dorothy E. (1919-1999),

a nursing theorist who developed a behavioral systems model presented in Conceptual Models for Nursing Practice (Riehl and Roy, eds., 1973). Johnson's theory addresses two major components: the patient and nursing. The patient is a behavioral system with seven interrelated subsystems. Each subsystem has structural and functional requirements. The structural elements include drive or goal; predisposition to act; choice, alternatives for action; and behavior. The attachment-affiliative subsystem forms the basis for all social organization. The dependency subsystem promotes helping behavior. The biologic (ingestive and eliminative) and sexual subsystems have to do with social and psychologic functions as well as biologic considerations. The function of the achievement subsystem is to attempt to manipulate the environment. The functions of the aggressive subsystem are protection and preservation. Johnson considered that problems in nursing are caused by disturbances in the structure or functions of the subsystems or the system. Her behavioral systems theory provides a conceptual framework for nursing education, practice, and research.
