Aimed at undergraduate courses in health psychology, this text takes a broad approach to the study of the science that connects behaviour to health and health to behaviour. Taking an epidemiological approach to the field, it goes beyond the study of psychological processes in the individual, such as stress and coping or personality factors, to examine the interrelationship between health and human behaviour from a variety of perspectives. Balanced between biological, behavioural and clinical aspects of health psychology, the text covers a broad spectrum of subjects from research methods, behavioural epidemiology, AIDS, cancer and cardiovascular disease. The authors provide a focus of development and implementation of health programmes, as well as coverage of various community-wide epidemiological studies and their importance in the field of health and human behaviour.
