So I was wondering if there may be a way to incorporate chat between participants in SoSci Survey?
There used to be a survey project in 2020 (before Corona), that got their respondents into a lab. Then, by using the database content contents, they realized something like a chat. Not real-time, but "statement" -> next -> "see other's statements and answer" -> next -> and so on.
The key challange then was to get the respondents synchronized, because even if they start the questionnaire at the same time, they tend to arrive at the "chat" page at different times. If you do not work in a lab, that challenge becomes an even greater issue.
And then there's also the challenge how to assign chat-pairs. If you do so at the very beginning of a survey, then one may stop answering on page 3, and the other one has no chat-partner left.
So, aside from the fact that SoSci Survey does not yet provide a chat feature in the narrow sense, there are significant organizational challenges to overcome in order to make a useful online design with a chat.
