Behavior change communication strategies.

Appropriate and effective communication is central to the success of interventions to reduce the risk of HIV infection. This paper reviews what has been learned about the nature of communication in the behavior change process. It examines the contexts in which communication occurs, as well as the contribution of communication theory, social marketing theory, and structural intervention theory to intervention development. Guidance is offered on the most appropriate ways in which to communicate with different groups and audiences, and future priorities for research and intervention are identified.
