Setting up a database link for group questionnaires

You are here:
< All Topics

A group questionnaire is a questionnaire that you want your participant to repeat a number of times, once per subject. For example, a participant may be based in more than one office and they need to complete the questionnaire once for each office. The spreadsheet below shows how you can lay out the spreadsheet with one row for each office required.

The participant data file must include a login, which can be an email address, and the subject field. In addition, the data may optionally contain an email address, password and other seeding information, for example, first name used to personalise the email invitations.

When the participants start the questionnaire via the survey link, they are shown a list of the subjects available to them, together with the questionnaire status (started, completed, etc) for each subject. The participant starts each group questionnaire by clicking on the subject.

The responses for all the group questionnaires can be analysed together, so you can make direct comparisons between evaluations of different subjects.
