what is roy's theory of nursing
In 1976, Sister Callista Roy developed the Adaptation Model of Nursing, a prominent nursing theory. Nursing theories frame, explain or define the provision of nursing care. Roy's model sees the individual as a set of interrelated systems (biological, psychological and social).asic to Royâs model are three concepts: the human being, adaptation, and nursing. The human being is viewed as a biopsychosocial being who is continually interacting with the environment. The human beingâs goal through this interaction is adaptation.
