Developing the research agenda could be characterized as a synthesis of the field's current status and needs. The project staff and advisory board will craft questions to collect data from the online panels in an iterative fashion. Online panel discussions will occur in three rounds, using a modified Delphi procedure. Between-round analysis will identify areas of consensus and disagreement for confirmation/exploration in later rounds. The results of the panel discussions will be presented in the webinar discussions and face-to-face conference to support development of the research agenda, prioritization of research questions, and modeling of designs for priority studies.
