Time trade-off (TTO) and discrete choice experiment (DCE) preference-elicitation techniques can be administered using face-to-face interviews (F2F), unassisted online (UO) surveys, or remote-assisted (RA) interviews. The objective of this study was to explore how the mode of administration affects the quality and reliability of preference-elicitation data. EQ-5D-5L health states were valued using composite TTO (cTTO) and DCE approaches by the UK general population. Participants were allocated to 1 of 2 study groups. Group A completed both F2F and UO surveys (n = 271), and group B completed both RA and UO surveys (n = 223). The feasibility of survey completion and the reliability and face-validity of data collected were compared across all modes of administration. Fewer participants reported receiving sufficient guidance on the cTTO tasks during the UO survey compared with the 2 assisted modes. Participants across all modes typically reported receiving sufficient guidance on the DCE tasks. cTTO data were less reliable from the UO survey compared with both assisted modes, but there were no differences in DCE data reliability. cTTO data from all modes demonstrated face-validity; however, the UO survey produced higher utilities for moderate and severe health states than both assisted modes. Both F2F and RA modes provided comparably reliable data. The reliability of DCE data is not affected by the mode of administration. Interviewer-assisted modes of administration (F2F or RA) yield more reliable cTTO data than unassisted surveys. Both F2F and RA surveys produced similar-quality data. • Preference-elicitation tasks can be administered using various modes of administration, ie, face-to-face (F2F), online remote assisted (RA), or online unassisted (UO). Existing literature suggests that the mode of administration of preference-elicitation tasks can influence the resulting data. • This study compared discrete choice experiment (DCE) and composite time trade-off (cTTO) data across all 3 modes of administration. This study adds to the literature by examining the quality of latent-scale DCE and cTTO data elicited via UO surveys compared with 2 different interviewer-assisted modes (F2F and RA). The study also strengthens existing findings from recent studies comparing F2F with RA interviews for conducting cTTO studies. • The findings from this study support conducting DCE studies to value health states using any mode of administration. cTTO data quality in this study was, however, affected by mode of administration; higher quality data were obtained from F2F and RA modes compared with UO. Interviewer-assisted modes are recommended for cTTO studies based on these findings, although future research should explore optimizing online cTTO surveys to potentially enable high quality data collection from UO settings.
