Health Psychology: Biopsychosocial Interactions First Canadian Edition helps students to understand the interplay of biological, psychological and social factors in people's health. It has a modular structure, which allows instructors to choose to cover all of the systems at once or distribute them to other chapters. The psychological research cited in the text supports a variety of behavioural, physiological, cognitive, and social/personality viewpoints. The Canadian edition includes health care systems in a Canadian context as well as discussions of health issues affecting marginalized groups, stress, substance use, health services, fetal alcohol syndrome, aboriginal issues, and material on social inequalities in the health services section. The book also includes international examples and cross cultural references to broaden the psychologist's view of health issues around the world and to highlight what works in the field.
