Using data from a non-mobile-optimised survey in the UK, this paper compares the quality of survey data from mobile devices with different screen size. The findings suggest that data quality mainly differs between small smartphones with a diagonal screen size of below four inches and larger...

We attempt to isolate the causes of mode effects on measurement in a comparison of face-to-face and telephone interviewing, distinguishing between effects caused by differences in the type of question stimulus used in each mode (audio vs. visual) and effects caused by other differences between...

Whether questions and answers are transmitted between interviewer and respondent by visual or aural communication can affect the responses given.

Our paper provides an empirical study of whether satisficing is related to social desirability bias using real-world eye-tracking. The method enables detecting latency of eye gazes in web, face-to-face and paper and pencil self-administered (SAQ) modes. Through these we infer respondents'...

With proactive dependent interviewing respondents are reminded of the answer they gave in the previous interview, before being asked about their current status. We examine the risk that respondents falsely confirm the answers from the previous interview as still applying, using data from a panel...
