About This Webinar
Individually randomized group-treatment (IRGT) trials are studies in which individual participants are randomly assigned to study conditions, but treatment is administered in groups. Because participants share a group environment and interact with each other, observations taken on participants may be correlated within treatment groups. This correlation must be taken into account in design and analysis of IRGT trials, and many appropriate methods may be drawn from the literature on group-randomized (or cluster-randomized) trials (GRTs).
However, there are important differences between GRTs and IRGT trials, and more work is needed to adapt GRT methods or develop new methods. This webinar will provide an introduction to IRGT trials, review current approaches to design and analysis, and highlight areas where further work is needed.
