Abstract

Despite a sharp increase in online-surveying in the last years, surveys conducted via telephone still are and are going to remain an important tool for academic as well as commercial survey research.

If a survey is conducted via landline and mobile phones, it can be seen as a form of mixed-mode survey: interview data is gathered by competing modes of data collection (in addition to "classic" mixed-mode surveys conducted via mail and face-to-face, via mail and telephone, combining online and other modes of data collection). There are processes specific to these mixed-mode telephone surveys, as well as specific sources of error may disturb inference based on mixed-mode telephone surveys. In order to fully understand these processes and avoid or minimize mixed-mode specific errors, the project aims at summarizing knowledge about mixed-mode telephone surveys and to provide best-practice guidelines to people planning to design and conduct telephone surveys mixing landline and mobile phones.

Within the project, data from several mixed-mode telephone surveys are being analyzed. These surveys cover a large range of topics and methodological survey design aspects. Especially the opportunity to use paradata (i.e. data describing each single contact attempt) from these surveys, allows gaining insights into possibly different processes of landline or mobile phone surveys. These data stem from different surveys conducted by GESIS, the University of Dresden (TU Dresden), the fieldwork institute USUMA, and the Robert Koch Institute (RKI, German government's central scientific institution in the field of biomedicine).

The project aims not only at describing and comparing different data quality aspects but at drawing conclusions and giving recommendations based on empirical evidence in order to preserve if not to increase data quality of telephone surveys, especially mixed-mode telephone surveys to keep them a valuable tool for survey research.

Thus, insights and results from the project are believed to be of great practical importance to all who are faced with conducting mixed-mode telephone surveys, not only academic-driven but also (scientific) commercial survey Research.
