ABSTRACT: Dissemination often is the neglected phase of the development and distribution cycle. While attention has focused on developing and testing new health education and health promotion programs, relatively little effort has been placed on studying how the programs can be disseminated. This paper reviews the dissemination process, identifies factors critical to successful dissemination, uses examples from a community-based heart disease prevention study to illustrate how health promotion programs can be disseminated across a community, and suggests ways these methods might be applied to a community-based approach to adolescent drug use prevention.
