Trends in how illness has been viewed
Western view (traditional)
Biomedical model — illness is caused by
physical phenomena (e.g., germs, cell
abnormalities) -- reductionistic
Biopsychosocial
Perspective
The view that health is determined by the
interaction of biological mechanisms,
psychological processes, and social influences
Biological mechanisms: genes, evolutionary history,
anatomical/biological makeup, nutrition
Psychological processes: coping mechanisms, attitudes
toward treatment, personality/outlook on life
Social context: SES, social network, societal and cultural
norms (e.g., pervasive consumption of soda)
