This course is an introduction to social and behavioural theory as it applies to the understanding of health and illness. As such, it is a survey course meant to acquaint you with many of the major areas of inquiry, questions, debates and arguments — and the work of key authors — in the sub-field of the sociology, psychology, and social science of health. Emphasis will be on a critical analysis of competing discourses on health, including those based on health behaviour change, interpretive perspectives, critical political economy, Foucauldian perspectives, indigenous perspectives, critical realism, and more. The focus of discussion will be theoretical interpretations of what it means to be, and what causes us to be, healthy or ill in Western industrialized society.
