Classification of Nursing

Theories

  1. Needs theories.
  2. Interaction theories.
  3. Outcome theories.
  4. Humanistic theories
  • These categories indicate the basic philosophical base of the theories

1. Needs theories

  • These theories are based around helping individuals to fulfill their physical and mental needs.

“This theories are relying too much on the medical model of health and placing the patient in an overtly dependent position”.

3. Outcome theories

  • These describe the nurse as the changing force, who enables individuals to adapt to or cope with ill health.
  • “This theories are too abstract and difficult to implement in practice”.

4. Humanistic Theories

  • Humanistic theories emphasize a person’s capacity for self actualization.
  • Humanists believes that the person contains within himself the potential for healthy and creative growth.
  • Abdellah et al (1960) emphasizes

delivering nursing care for the whole person to meet the physical, emotional, intellectual, social, and spiritual needs of the client and family.

  • Orlando 1962: the client is an individual; with a need; that, when met, diminishes distress, increases adequacy, or enhances well-being.
  • Johnson’s Theory 1968: focuses on how the client adapts to illness and how actual or potential stress can affect the ability to adapt.
  • Orem1971: Nursing care becomes necessary when client is unable to fulfill biological, psychological, developmental, or social needs.
