The study of behaviours that influence health and the factors determining which individuals perform such behaviours has become a key area of research within health psychology. This book provides an overview of current research and practical details of how to apply the most widely used social cognition models to predict and change health behaviours. This popular, established text has been expanded to include the most up-to-date research on social cognition models and health behaviours. This third edition takes account of important developments in the field, and features: Four new chapters on Self-Determination Theory, Prototype-Willingness Model, Health Action Process Approach and Behaviour Change Techniques Thoroughly updated chapters on Health Belief Model, Protection Motivation Theory, Social Cognitive Theory, Theory of Planned Behaviour, Implementation Intentions and Stage Models New material on using theories to change health behaviours. Predicting and Changing Health Behaviour boasts many of the leading names in the field and provides key reading for advanced undergraduate and postgraduate students, health promoters, health psychologists and others interested in understanding and changing health behaviour. Conner and Norman's book has become the cornerstone of teaching of social cognition models in health psychology courses and the update is very welcome. The new edition retains the format that makes the book very accessible to researchers, teachers and students alike i.e. a thorough overview of each of nine theoretical approaches by prominent researchers, describing recent developments and relevant research findings. The final chapter by the editors identifies important cross-cutting issues and pointers to future trends. In sum, this is the definitive text in this important area of research and application.
