Within the CESAR group, one project was to develop a questionnaire to collect standardized demographic data. The idea was that all members could use the same items when collecting data to make it easier to merge and/or compare datasets, but also to reduce time consumption and effort by offering a completed questionnaire that can be added to the other measurements. Off-course, questions can be left out, added or modified to better suit the aim of the study.
If you are interested in using the questionnaire, this can be obtained from Ghassan Mourad by e-mailing firstname.lastname@example.org.
When using the questionnaire, the Cesar group should be cited.
