This analysis examined the importance of quality feedback in Delphi processes. The findings: 1) showed that participants in Delphi studies tend to change at least some of their responses after group feedback and discussion; 2) illustrated that iterative data collection helps build consensus; 3) supported previous findings about the modest magnitude of response changes between Delphi rounds; and 4) suggested that even modest changes may affect the final study findings.
