This article describes the evaluation of the HIV/AIDS communication aspect of the multi media Soul City health promotion intervention in South Africa. The intervention consists of a television and radio drama and print material. The evaluation was multifaceted with a before and after national survey and a national qualitative study. In the before and after survey change was measured and then multiple regression analysis was performed to assess the variables associated with the change. The qualitative study consisted of focus group discussions, which were analysed thematically. The studies show that there are numerous instances of community change and how the change is mediated at the community level. The studies also describe the change at a number of levels of the described behaviour change model for individuals.
