Health promotion is the process of enabling people to increase control over, and to improve, their health through the provision of information. This volume for health promotion specialists offers practical guidance in, and advice on, three main areas: assessing existing evidence; collecting new evidence; and providing practicable solutions when there is not any evidence. It should enable practitioners to think more broadly about what "doing the right thing" and "doing things right" means, and to use this thinking to inform and educate their practice. Contributions are drawn from experienced health promotion specialists, practitioners and managers.
