Web surveys are becoming increasingly popular in survey research including stated preference surveys. Compared with face-to-face, telephone and mail surveys, web surveys may contain a different and new source of measurement error and bias: the type of device that respondents use to answer the survey questions. This is the first study that tests whether the use of mobile devices, tablets or smartphones, affects survey characteristics and stated preferences in a web-based choice experiment.
More time use surveys use phone apps or web collection to expand the range of information collected while decreasing respondent burden and survey costs. These new modes change reporting in subtle but significant ways, prompting more short spontaneous activities, particularly movement between places and use of electronic communications. New modes also register details not necessarily noticed by participants, revealing a need for mixed mode tests to retain comparability with the rich history of time use data. This presentation uses a time diary surveys conducted in the UK by the Centre for Time Use Research from 2011 to 2015.
This paper shows the mobile device adoption rate of the American Life Panel (ALP) after the introduction of the new responsive design, and compares the rates between tenured respondents that experienced the shift and a refreshment sample that only received the new responsive design, as well as other demographic variables. In particular, the change in behavior of the long-term panel members who saw the transition is examined. We discuss the implications of our findings for mobile-compatible web surveys.
In this exploratory study, WhatsApp survey data is compared to previously collected face-to-face, telephone and Web survey data. We did not find significant effects for non-differentiation and acquiescence between WhatsApp mode and the other modes. For acquiescence, respondents seem to show least bias in the WhatsApp survey and most bias in face-to-face interviews. For potential social desirable behavior, our findings are mixed. As regards to user experience, respondents expressed positive attitudes towards convenience of answering questions, but open-ended questions that need much text were not appreciated, and some respondents were worried about their privacy.
