This talk will discuss a newly developed multi-method approach to combining mobile calling and texting log data with traditional survey and interview techniques. This approach involves a system in which an online portal is used to customize the actions of a smartphone based data collection application. These actions include the collection of non-identifying calling and texting log data, on-screen survey questions, and dynamically drawing on log data to generate questions and stimuli for use during in-person interviews. This talk will also discuss ways of collecting this data without compromising respondent privacy, and it will touch on ways of analyzing the large and complex data that this multi-method approach produces.
