The poster "Intervention through Mediators/Multiplicators" outlines a extended model for mediators and multiplicators. It mentions different sources of the idea to use mediators or multiplicators and shows, how they can be engaged in different tasks. A combination of both concepts to one model for mediators/multiplicators seems to be favorable for interventions in social and preventive medicine.
