    Our Mission


  • With our cognitive pretests, we support researchers in the development or adaptation of survey instruments to ensure that the questions or items are understandable and interpreted as intended. More information about our services can be found on our website.
  • Methodological research is our passion! We regularly publish our research results in international peer-reviewed journals and are constantly developing our services on the basis of the results. In recent years, we have expanded our portfolio of methods to include pretests with web probing and eye tracking, among others.
