I am redesigning a survey flow. My product team noticed higher drop-off rates with multiple choice questions – the answers often require the user to scroll, and they can't see all of the options at once. There is no way to avoid it (as far as I know). How might we design long multiple-choice questions to be more user-friendly on mobile, so that we can improve their response rates?
There is no great way to solve this issue because, as you mentioned, would have a long list of multiple answers. A possible solution if applicable would be List the 2 or 3 most popular answers and another one entitled “Other”. When tapping “other”, you would extend the list with the remaining options.
Also take into consideration to not list all questions at once but to present them wisely, to avoid choice paralysis as much possible.
