Jean Watson is a recognized nurse theorist in the United States who founded the theory of human care. The concept of care of humans in Watson is simple, but it has great depth and meaning and for nurses it can work in a compassionate, intelligent, loving and caring manner. All our nurses need human-care theory because our work is to care for other people in a truly sensitive way. The theory is broad and its basic foundation is based on nine interrelated concepts focused on nurses who give consideration, wisdom, love, and care to patients (Watson, J., 1999).
The theory of nursing environment is the theory of patient care. In other words, it focuses on patient care, not the relationship between care process, patient and nurse, or individual nurse. In this way, the model must adapt to the needs of the individual patient. Environmental factors affect the condition and disease of various patients. And the nurse has to deal with it on a case-by-case basis so that factors can be changed in the best way for individual patients and others. Her needs
Dorothy Orem 's theory of self - health disorder and sister' s Callista Roy's adaptation model are ambitious nursing theories, but their applicability is the same as the middle distance theory. Large scale nursing theory consists of a conceptual model including the main contents of nursing research and oversees the development of midrange theory for nurses and other medical professionals. According to research by Walker and Avant (2011), these theories "conceptually classify medicine from medical care by demonstrating the existence of different nursing viewpoints".
Dorothea Orem's Self Care Insufficient Care Theory Orem explains her theory as a general theory consisting of three related theories, self-care theory, self-care deficit theory and nursing system theory. Self-care theory explains why and how people care about themselves. The deficit in self-health theory explains and explains why people can get help through nursing care. Care system theory explains and explains the relationship that must be present and care must be maintained. These three relations theories constitute Orem 's general nursing theory called self care care deficit nursing theory (Berbiglia, 2010; Orem, 1990; Taylor, 2006).
