Is it possible to assign questionnaires/activities to subjects individually? So we would like to personalize/individualize questionnaires, but not based on participants’ answers, but assign questionnaires manually by us investigators (This would be significant as soon as we have to divide subjects into two groups without them noticing). So far I have read about the “Criteria” and “Placeholder” settings, but they are not helpful for us.
Is this possible?
Thank you very much for the support and information!!
