This volume argues the case that public health communication has affected health behavior. It brings together 16 studies of large-scale communication in a variety of substantive health areas--tobacco, drugs, AIDS, family planning, heart disease, childhood disease, highway safety--prepared by the authors who did the original research. These studies show important effects and illustrate the central conditions for success. The book also includes complementary analytic chapters which provide a meta-analysis of published results, some approaches to developing communication interventions, and alternative methods for evaluation of public health communication projects. <br> <br> Including studies based on communication programs in the United States, as well as projects done elsewhere in the world, including Europe, Africa, Asia and Latin America, this book: <br> *offers a broad presentation of the alternative research designs that have been used to evaluate public health communication programs; <br> *includes a great range of approaches from field experiments and natural experiments to simple before-after and complex time series designs, using data gathered from individuals and from archives; and <br> *utilizes an innovative perspective on how to exercise public health communication from a leading and thoughtful practitioner. <br> <br> As such, it is required reading for scholars, students, practitioners, and policymakers in public health, health communication, health psychology, and related areas.
