Question

Quizplus · Accepted Answer

Behavioural medicine is the field that reflects the shift in focus from infectious disease to psychological/behavioural factors as causes of illness and death. It incorporates knowledge from psychology, psychiatry, and medicine to understand how behaviour and lifestyle can affect health outcomes. Medical psychology is a related field, but it focuses more on the psychological aspects of illness and treatment. Epidemiology and community psychology are not specifically related to this shift in focus.
