Key Concepts in Health Psychology aims to provide the reader with a comprehensive understanding of the key issues, theories, models, and methods in contemporary health psychology. It allows the reader the opportunity to engage with a full range of approaches and methods in a very diverse field, and importantly to be able to appreciate the relationships between these. While current textbooks in health psychology offer the reader some conceptual reasoning about different aspects of the discipline, there is no one source which provides an accessible, navigable, and cross-referenced analysis of the major models and ideas. The influences and foundations of this important field are vast and sometimes challenging for students studying it in various disciplines. This textbook presents the core bases of the field in a manner that should make teaching and learning more inviting and exciting. Key Concepts in Health Psychology is a core textbook for all undergraduate and graduate students taking Health Psychology for the first time, and strongly recommended to students taking the course in Allied Health and Medical disciplines.
