Guide for Pretesting DCEs

Domain	Guiding questions for researchers
Content Relevance and comprehensiveness of the DCE	Do attributes collectively capture the concept of interest? Are attributes/levels appropriately ordered? Are levels appropriate values? Are topic and elicitation relevant to the decision context?
Presentation Visualization and formatting of the DCE	Do color, images, and layout effectively convey the intended messaging? Are materials (i.e., introduction and example tasks) informative? Is the order that information is presented in logical? Is presentation optimized to reduce participant burden?
Comprehension Understanding of the DCE	Are key terms understood? Can respondents envision the scenario? Is there an appropriate recall of key terms? Are all materials consistently comprehendible?
Elicitation Process of making a choice in the choice task of the DCE	Are tradeoffs being made? Are underlying heuristics driving decision making? Is outside information being included in decision making? Are responses consistent with participant preferences?
