Text messages to incentivise response in a web-first sequential mixed-mode survey
20 Apr 2022
This working paper reports research exploring the benefits of adding text messages to the contact strategy in the context of a sequential mixed-mode design where telephone interviewer administration follows a web phase. We present results from a survey experiment embedded in Wave 11 of Understanding Society. Effects of the text messages on survey response and fieldwork efforts were assessed. We also investigated the effect on the device selected to complete the survey, time to response, and sample balance. The results show a weak effect of the SMS reminders on response during the web fieldwork. However, this positive effect did not significantly reduce fieldwork effort.
