Designing mixed-mode surveys

This weekend is the deadline for submitting a presentation proposal to this year’s conference of the European Survey Research Association.

As in previous years, it looks like the most heated debates will be on mixed-mode surveys. As survey methodologists we have been struggling to combine multiple survey modes (Internet, telephone, face-to-face, mail) in a good way.
