WASS Lunch seminar 'Another look at data quality in large scale survey research'

Speaker: Jörg Blasius, University of Bonn

After the lunch seminar, WASS PhD candidates will have the opportunity to meet Professor Blasius during a one hour Q&A session, in which they can ask questions related to their own research projects. This Q&A session will be guided by dr. Hilde Tobi, head of the Research Methodology Group.

Many social scientists use data obtained in large international surveys and pay for data obtained through survey research organisation (SRO). The quality of survey data for any questionnaire is a function of the respondents, the interviewers, and the employees of the SRO. I will show that task simplification dynamics can occur at each of these levels and the effect of such task simplifications reduced quality of the data. The precise form of task simplification differs at the three levels. For respondents it might take the form of utilizing only specific parts of the available response options; for interviewers it can take the form of asking primarily the demographic questions and fabricating plausible responses for the remainder; for interviewers and employees of SROs it can take the form of near-duplication of entire questionnaires. I analyse well-known cross-national surveys such as the European Social Survey to document various task simplification (and time saving) techniques with special emphasis on interviewers. The procedures to identify suspect interviewers will be explained, and procedures to identify fraudulent interviewers already during the field-period will be discussed.  

Keywords: data fabrication, interviewer effects, cross-national comparisons, response styles, task simplifications.
