Session: Design and Analysis of Community-Randomized Intervention Studies
3225.1: Monday, December 12, 2005: 12:30 PM-2:00 PM
Oral
Design and Analysis of Community-Randomized Intervention Studies
Community- or group-randomized trials arise in many contexts, either because implementation logistics dictate such an approach, or because the total intervention effect is of interest when applied to a group of people. This session will treat both design and analytic features of group-randomized trials, and present a number of novel approaches of use to investigators and statisticians.
Learning Objectives: 1. Learn why constrained randomization can be useful in community randomized trials, and how this can be implemented in a phased implementation trial. 2. Assess issues associated with spatial autocorrelation in the design and analysis of experiments 3. Appreciate the importance of cost-effectiveness analysis of outreach interventions in community randomized trials 4. Understand the two-stage approach to the analysis of community-randomized trials using generalized linear mixed models
