Diffusion of an effective tobacco prevention program. Part I: Evaluation of the dissemination phase

As health promotion methods are proven effective, the diffusion and widespread implementation of successful programs can significantly reduce behaviors that pose risks to health within a targeted population. The Smart Choices Diffusion Project developed and evaluated a dissemination intervention program that targeted 128 school districts in east Texas. The project employed a theory-based model to disseminate information about a proven tobacco prevention program to opinion leaders in each district. These opinion leaders were asked to personally communicate the program information within their district using a videotape and printed materials, and advocate for program adoption. In addition to personal communication, a newsletter linked school districts. Opinion leaders in 52% of the districts showed the videotape, which modeled program adoption. A quasi-experimental design was used to evaluate the impact of the dissemination phase on teachers' and administrators' readiness to adopt a tobacco prevention program. Evaluation of the dissemination phase revealed no differences between the intervention and comparison districts in a district's readiness to adopt a tobacco prevention program. However, in intervention districts where school administrators viewed the videotape, the administrators were more likely to perceive the innovative program as having a relative advantage and to perceive their district's organizational and social environment as supportive of adopting the program.
