The UK Household Longitudinal Study, also known as Understanding Society, had used face to face interviewing since it began in 2009. In 2016, wave 8 of the survey took a leap into mixed mode interviewing with 40% of the sample being asked to participate online initially, before being followed up face to face.
This paper will look at the overall effects of the move to web on response rate (and therefore attrition) as well as whether there are particular groups for whom the move to web has increased or decreased response, with a focus on groups that have tended to have higher levels of attrition on the face to face waves of the study. The paper will also discuss the particular strategies used by the study to boost response in a mixed mode context and the relative success of these.
By summer 2017 we will also have early response data from wave 9 of the study, so will have some initial findings on whether the mode of response at one wave appears to affect participation at the following wave.
