Jean Watson was a nurse scholar known for developing the Theory of Human Caring. She received several academic degrees including a PhD in nursing. Watson authored numerous books that outlined her theory, which focuses on caring as central to nursing. The theory proposes 10 carative factors that guide nurses to address patient's psychosocial needs through compassionate care. A core concept is the transpersonal caring relationship between nurse and patient. Critics note the theory may be difficult to apply in modern hospital settings with short patient stays. However, Watson's work emphasizes the humanistic aspects of nursing care.
