Final answer:
The Adaptation Model was developed by Sister Callista Roy. It is a comprehensive framework used in nursing to help assess and promote patients' adaptation to changes and stresses, thereby supporting their health and wellness.
Step-by-step explanation:
The theory that was developed by Sister Callista Roy is the Adaptation Model. Sister Roy, a nursing theorist, introduced this model in 1976 as a framework for nursing practice, education, and research. The central tenet of the Adaptation Model is the ability of individuals to adapt to environmental changes and stresses through biological, psychological, and social means. This model posits that health and wellness depend on the individual's ability to respond and adapt to these changes effectively. It encompasses four adaptation modes: physiological-physical, self-concept-group identity, role function, and interdependence, which collectively account for a person's adaptability and subsequent health status.
In the context of healthcare, nurses apply the Adaptation Model to assess patients' adaptive responses to illness, stress, and health challenges, and to plan interventions that promote positive adaptation. Through understanding the individual's adaptation level, healthcare providers can better support patients in achieving their highest level of health.
