Mobile Phone Surveys: Empirical Findings from a Research Project

The growing number of mobile-only households across Europe and in Northern America is at present one of the key challenges for survey research. So far, frames for telephone survey sampling include only landline phone numbers. But in future landline phone surveys and mobile phone surveys will have to be combined. However, at present there are a lot of practical questions unsolved. In this paper we want to present some findings of a recent research project where we recruited individuals for an experimental mobile phone panel. Our main objective was to study their response behavior. In the first chapter we explain the motivation for our research. Then we describe the fieldwork of our study in detail to show which efforts are necessary to conduct a mobile phone survey. In the third chapter we show some findings on the response behavior of the panelists. Finally, we give an outlook on future telephone surveys where the dual frame approach will become the usual method

Combining landline and mobile phone samples: a dual frame approach

"More and more households abandon their landline phones and rely solely on cell phones. This implies a challenge for survey researchers: since the cell phone only households are not included in the frames for landline telephone surveys, samples based on these frames are in danger to be seriously biased due to undercoverage, if respondents who do not have a landline are systematically different from respondents who have a landline. Thus, strategies for combining samples from different frames need to be developed. In this paper we give theoretical foundations for a dual frame approach to sampling, explain how samples can be optimally allocated from these two frames, and describe an empirical application of a survey conducted in Germany that used a dual frame approach."
