Abstract
Numerous school health education programs have been developed. No matter how effective a given program may be, however, its impact will be determined by the extent to which it actually is disseminated and maintained in classrooms. The dissemination of a program involves purposeful efforts by agencies usually outside the school to implement the program in many different schools, while program implementation involves efforts by those within a given school to effectively use the program in its classrooms. This paper has been prepared to review concepts, strategies, and methods used to study dissemination and implementation; to specify the functions of dissemination and implementation research; and to describe general approaches and specific procedures to evaluate the effectiveness of dissemination and implementation activities. As we develop more and better school health education interventions, the need for research that will allow us to efficiently transport these interventions to classrooms throughout the nation becomes increasingly important.
