The integration of QR codes (quick response codes) in web surveys has become commonplace, aimed at simplifying survey access for respondents using mobile devices. While previous studies have presented mixed findings regarding the effectiveness of QR codes in enhancing survey participation, this research re-examines their impact on survey breakoff, identifying potential explanatory factors such as the screen resolution of the respondent’s device. Drawing on data from the Digitize! Online Panel Survey, a probability sample of up to 1,228 respondents in Austria, this study uses an exploratory research design to investigate how screen resolution, QR code usage, and frequency of personal computer or mobile device use influence survey breakoff behavior. We find that QR code utilization alone does not significantly predict survey breakoff once other covariates are accounted for. However, the resolution of the device used for the survey emerges as a critical determinant, with higher resolutions associated with lower probability of survey breakoff. The study thus uncovers a nuanced relationship between screen resolution and survey breakoff, particularly noticeable when transitioning from mobile devices likely to be smaller, such as smartphones, to those with larger screens, like tablets. While QR codes offer convenience and accessibility advantages, their implementation requires careful consideration to mitigate potential drawbacks and optimize survey engagement. Overall, this study contributes valuable insights into the evolving landscape of digital survey methodologies, highlighting avenues for future research to enhance data validity and reliability.
