Title The Impact of Adding e-Interviewers To Web-Based Research
Year 2001
Access date 22.04.2004
Abstract This paper highlights the results of a recent study conducted jointly by Brigham Young University (BYU) and humanvoice, inc. testing the data effects of adding an e-Interviewer to web-based, quantitative research. Using widely available technologies, a split sample survey was conducted of BYU alumni which asked attitudinal questions about various BYU publications. A survey programmed identically in CATI, self-administered Internet and e-Interviewer assisted Internet modes was designed to test the effects each mode would have on data quality. The e-Interviewer version yielded significantly fewer mid-terminations, especially in those respondent groups previously proven to be most likely to terminate Internet surveys and self-administered surveys. It also yielded longer open ends, screened out more ineligible respondents or “cheaters” than the self-administered Internet version of the study and improved sample frame coverage by almost 100%. All these effects were observed despite the fact that the e-Interviewer version averaged 15 minutes longer than the self-administered Internet version. Different mode effects were observed for different types of questions. In some cases, CATI proved to be better than any other mode for producing data quality.
