BASIC PROCESSES IN THE DEVELOPMENT OF NURSING THEORIES
Nursing theories are often based on and influenced by broadly applicable processes and theories. Following theories are basic to many nursing concepts.

A. General System Theory:

  • It describes how to break whole things into parts and then to learn how the parts work together in " systems".
  • These concepts may be applied to different kinds of systems, e.g.. Molecules in chemistry , cultures in sociology, organs in Anatomy and health in Nursing.


B. Adaptation Theory

  • It defines adaptation as the adjustment of living matter to other living things and to environmental conditions.
  • Adaptation is a continuously occurring process that effects change and involves interaction and response.

Human adaptation occurs on three levels:
--- the internal ( self )
--- the social (others)
--- and the physical ( biochemical reactions )

C. Developmental Theory

  • It outlines the process of growth and development of humans as orderly and predictable, beginning with conception and ending with death.
  • The progress and behaviors of an individual within each stage are unique.
  • The growth and development of an individual are influenced by heredity , temperament, emotional, and physical environment, life experiences and health status.


COMMON CONCEPTS IN NURSING THEORIES
Four concepts common in nursing theory that influence and determine nursing practice are

  1. The person( patient)
  2. The environment
  3. Health
  4. Nursing (goals, roles, functions)

Each of these concepts is usually defined and described by a nursing theorist. Of the four concepts, the most important is that of the person. The focus of nursing is the person.
