But hopefully the survey is going to be used only on bigger screens.
Unfortunately, this is rather wishful thinking. I just ran a survey among company employees and we specifically told them that they should answer on ther computer or notebook and not on a tablet or a smartphone, because one of the questions was an array with 7 columns (number input) and a variable amount of lines (subquestions in Limesurvey).
But even when stated in the email and in the introduction text of the survey, there are always people who will not read it and then wonder, why it takes them so long to fill in the questionnaire.
Surveys are generally not their primary concern and many people do it when they don't have much to do, so while they are commuting, waiting somewhere, etc. That is when they use their mobile phone.
It is difficult for us researcher, because sometimes a "nice" matrix question seems to be the obvious and easy solution, but with the mobile trend it is getting more an dmore difficult to use those type of questions. In my case I knew the respondents, they might even get in contact if something went wrong and I have sent them about 10.000.000 reminders and the company directors and area managers were interested that they fill the survey and that the response rate is high. But if you are running a survey with the general public, they might just leave your survey unanswered, if it is too complicated.
