Final answer:
The theory of health treatment that includes physical, psychological, and social aspects is known as the biopsychosocial model, which recognizes the interconnectedness of these factors in determining overall health and well-being.
Step-by-step explanation:
The theory of health treatment that incorporates physical, psychological, and social aspects to achieve health and well-being is known as the biopsychosocial model. This model suggests that health and illness are products of a combination of factors including biological characteristics, behavioral factors, and social conditions. Health psychologists employ this model to look at how these three aspects interact and affect overall health, often engaging in public policy, education, intervention, and research to help individuals improve their health. The model realizes the importance of an individual's social health, which is influenced by sociocultural factors and encompasses the support network and social pressures a person experiences.
This holistic approach recognizes that when one component of health falters, be it mental, physical, or social, it has a cascading effect on the other aspects, potentially undermining overall health and well-being. Therefore, promoting health and well-being involves understanding and addressing all these interconnected dimensions.
