Integrating Citizens Juries and Discrete Choice Experiments: Methodological issues in the measurement of public...

All health systems struggle with unlimited needs for healthcare, yet limited resources with which to address them. Under national health insurance systems, policymakers must make explicit and potentially contested decisions around resource allocation. Policymakers have recognized the need to include public values in decisions regarding the distribution of resources across competing health priorities. Given the complex nature of these decisions, however, research into how to effectively measure public preferences is underdeveloped. Measuring community values poses special challenges since they involve normative judgments that can be interpreted differently across individuals and communities. Researchers have previously proposed integrating two methods that are currently used for measuring public preferences around healthcare services: i) an individual survey instrument, the Discrete Choice Experiment (DCE) and ii) a group-based model that incorporates informed opinions and deliberative dialogue, Citizen Juries (CJs). This current paper proposes a framework for implementing that integration and assesses methodological issues in the integration of DCEs and CJs, including issues of generalizability and validity. CJs and DCEs have conflicting epistemological and methodological foundations, which impact how researchers might analyze results of the integrated method. Researchers and policymakers interested in measuring social values should determine the philosophical orientation of their research question prior to study design, which will assist in choosing an appropriate research method. Further research is needed to investigate the empirical validity of the integrated method and how it may be implemented to maximize public acceptance. Advancing these methods can provide an improved instrument for capturing public preferences for policymakers tasked with priority setting in diverse contexts.
