This book provides an introduction to psychology for allied health students and it encourages an understanding of the complex and interactive nature of the factors which influence an individual’s health behaviours and health outcomes. Through the use of real life examples, contemporary research and case studies students will be able to apply the material in the text to the health behaviours of the people they care for, their colleagues and themselves. Unlike many health psychology textbooks this new book examines individual personality and psychological theory within the social context of people’s lives. This approach is taken because of the increasing awareness that a person’s behaviour is not only influenced by internal biological and psychological factors, but also by external factors within the person’s social and physical environment. The first half of the book outlines psychological and other relevant theory whilst in the second half those theories are applied to health issues and healthcare practice. Chapters 15 presents psychological, lifespan and social theory; chapter 6 addresses the role and contribution of research to healthcare practice; and chapters 7 13 covers the psychological aspects of specific health encounters, issues and interventions.
