OBJECTIVES: Patient and citizens are increasingly asked to participate in surveys about health to promote community centeredness. Ethical standards govern how one might interact with respondents, but there is a paucity of research asking what potential respondents want out of this type of research. We sought to document the preferences and motivations of potential respondents to survey research.

METHODS: Respondents from a national panel completed a discrete-choice experiment comparing pairs of potential studies respondents could participate in at a local hospital. Studies were defined across six attributes (validity, relevance, bias, burden, time, and reimbursement) with three possible levels each. A D-efficient design resulted in three blocks of 12 tasks. A choice model was estimated using a continuous coded mixed logit and latent class analysis (LCA). After completing the survey respondents were asked which motivating factors they used to justify their choices from pre-defined list of factors that were identified through community engagement.
