Betty Newman’s System Model is a holistic and system-based approach to nursing (Alligood, 2014). This theory focuses on the response of the patient to environmental stressors. Every patient is viewed as a unique system of factors the respond differently to known, unknown, and universal stressors. Prevention is viewed as the primary intervention. She addresses five subsystems within a person: psychological, physiological, socio-cultural, spiritual, and developmental. There are six steps in Newman’s System Model for the nursing process: assessment, diagnosis, goal setting, plan, implementation, and evaluation. The goal of this model is to have harmony within each subsystem and move toward wellness.
Hettler (1976) created a model of wellness that is frequently used. It includes six dimensions: intellectual, spiritual, emotional, social, physical, and occupational. His theory is that all of these dimensions are interconnected and contribute to healthy living. When all of these dimensions are in line for a person, they will experience optimal wellness.
Both of these models are focused on wellness. Newman’s System Model (2014) and Hettler’s Six Dimensions of Wellness Model (1976) identify areas of a person that need to be fulfilled to achieve this ultimate goal. A practioner may be using Newman’s Model, while another may be using Hettler’s Model. Ultimately the goal is to provide wellness for their patient. Both models look at similar aspects of a patient that lead to the whole being highly functional.
