Abstract:
|
Many interrelated considerations go into the planning of a community intervention trial, including the nature of the desired outcome, the content and method of delivery of the intervention, and the characteristics of the target population. Geographical and social clustering in ethnic populations can present unique challenges and opportunities for study designers. For instance, media interventions are designed to impact an entire community, and the feasibility of randomizing communities may be adversely affected by geographical clustering. On the other hand, small group interventions can take advantage of pre-existing social clusters that facilitate randomization. In virtually all study designs, the impact of social networks on inter-cluster communication, and therefore possible contamination, must be considered. Examples of study designs that address these issues are presented.
