Final answer:
The biopsychosocial model is central to understanding health and well-being, as it focuses on multiple areas. Health psychologists investigate how genetics, behaviors, and social support impact health, and they study the interaction of biological, psychological, and sociocultural factors.
Step-by-step explanation:
The approach of focusing on multiple areas to understand health and well-being is central to the biopsychosocial model. Health psychologists investigate how genetics, behaviors, and social support impact health. They study the interaction of biological, psychological, and sociocultural factors to better understand and promote health. For example, they might research the relationship between one's genetic makeup, patterns of behavior, relationships, psychological stress, and health, and explore interventions aimed at changing unhealthy behaviors. The biopsychosocial model suggests that health and illness are determined by an interaction of these three factors.
