Experiences with multimode surveys

Surveys that employ simultaneous web, CATI, and paper modes (or any two-way subset) are increasingly common. Mathematica Policy Research, Inc (MPR) has deployed several of these types of surveys in Blaise. This paper reviews MPR's experiences and issues with these efforts by addressing instrumentation, survey management, and other considerations. The paper emphasizes the electronic implementation of these surveys and covers topics that emerge solely from the surveys' multimode nature; that is, material that goes beyond the implementation of a single-mode survey.
