This study examines the reach and impact of an adolescent reproductive health
intervention in Guinea. Over a period of roughly 8 months, the program used peer
education and mass media to reach youths, nested within a larger nationwide social
marketing program. The results suggest that short-term youth-targeted social marketing
programs (in this case eight months) may be able to improve reproductive health
knowledge, but that changing behavior requires a longer intervention, and further indicate
that low-budget peer educator interventions will, by definition, have a limited reach,
unless they are supplemented by intensive large-scale mass media activities.
