Objectives. Health care decision makers require public input to incorporate diverse values into programs and policies. Deliberation, one method for obtaining input, seeks to apply inclusive principles wherein diverse groups provide perspectives to inform decisions. We evaluate whether participants of different racial, ethnic, and educational backgrounds show differences in the effect of deliberation and the value placed on deliberation participation. Methods. We surveyed 907 participants before and after deliberation. Regression models examined associations between demographics and change in knowledge and attitudes, and perceived impact. Results. Changes in knowledge about using medical evidence in decision-making were not associated with race, ethnicity, or education. Changes in attitudes were not associated with these characteristics with one exception. African American, Hispanic, and participants with lower educational attainment reported more perceived impact. Conclusion. Similar results across demographic groups suggest deliberation’s promise for obtaining input from a diverse public to inform health programs and policies.
