Now in its fourth edition, Health Psychology takes a truly interdisciplinary approach to studying health psychology, and offers a comprehensive overview of the subareas within this fascinating subject. Fully revised to reflect current research and studies, and now in full color, the book includes new content on the impact of COVID-19 and greater coverage of health diversity. It unpacks the issue of social inequities in health by addressing how race and social economies have been traditionally confounded. The author achieves this by focusing on five systems that affect individual health outcomes: individual, family/community, social/physical environment, health care systems, and health policy. The social ecological perspective on health psychology creates a depth of understanding of the diverse facets of health, and examines health from a global perspective by exploring the impact of infectious and chronic illnesses both regionally and globally. This new edition has been packed with updated statistics and references, as well as helpful video links infused throughout, to actively engage readers in each topic. While grounded in psychology, the book incorporates perspectives from anthropology, biology, economics, environmental studies, medicine, public health, and sociology, and will be of particular interest to undergraduate students in health psychology and public health and for masters’ students of health psychology.
