Auto coding skipped questions vs. questions that were not displayed
We have a series of surveys with extensive branching, skip logic, etc. When we export the data, missing values for questions that were not displayed are indistinguishable from missing values for questions that were displayed but skipped by the respondent. I know that an easy way to distinguish between them would be to force responses, but ethically (and per IRB regulations) we cannot force participants to respond to every question, and requesting a response but allowing them to skip after a reminder gives us better data than forcing a response but offering a "refuse" option for every question.
Is there a way to automatically populate non-displayed questions with "999" or some other code? Or to populate questions displayed but left empty by the respondent with a similar code? We are collecting a very large amount of data monthly from a large panel of study participants over several years, so anything we can do to simplify high frequency checks and quickly identify how much data is actually missing (vs. not applicable) would be very helpful.
