Questionnaire design

The smartwielen questionnaire has been designed by a combined project team of the University of Luxemburg, the Zentrum fir politesch Bildung and the LISER. In order to guarantee for a comprehensive, significant, valid and politically neutral questionnaire, the team consulted with a large number of interest groups and civil society organizations, as well as journalists from multiple media organizations. Additionally, a workshop was organised for young people to make suggestions for questions. At the end of January 2019, a customized website was put online, allowing everyone interested to submit question suggestions. Below you will find a detailed description of the questionnaire design approach.

Below you will find a detailed description of those as well as the complete assignment of statements to the dimensions of the smartspider and the smartmap.
