Margaret Jean Watson developed the Philosophy of Human Caring theory and identifies 10 Carative Factors that are the basis of nursing care. The Carative Factors focus on meeting psychosocial needs and include forming humanistic values, developing sensitivity, cultivating trust, expressing emotions, and promoting spiritual well-being. Watson's theory emphasizes seeing the whole person within their environment and focuses on health promotion over illness. The theory's strengths are its holistic view of patients and emphasis on caring as central to nursing. Limitations include little focus on biophysical needs and need for more nursing research on applying the Carative Factors in practice.
