Summary: The aim of this study is to test a range of task presentation methods designed to simplify the DCE completion process in a multi-country setting using the EQ-5D-5L descriptive system. Methods We propose testing four separate approaches to presenting the DCE task, and testing these online with 1,200 general population respondents in Australia. Each respondent will answer 20 choice sets across two different presentation approaches (using 12 survey versions) to allow head to head comparisons between approaches. The design has been developed for a separate study, and consists of 120 EQ-5D-5L choice sets paired with one of four duration levels (2y, 4y, 8y and 16y). The presentation methods will be compared in a variety of ways. Firstly, head to head preference comparisons will give an indication of the acceptability of each approach. Secondly, regression analyses will be used to identify if any approach leads to better behaved data, in particular whether monotonicity is reflected in each dimension. Thirdly, the approaches will be compared to give insight into the thought processes of different types of respondent, and help to identify those who adopt a simplifying response heuristic at an early stage in the task.
