Cooperation and attrition rates in studies using new data collection technology

Between 2010 and 2014, several studies have been implemented in the LISS panel, using new, technologically innovative modes of data collection, such as internet weighing scales, smartphone apps, GPS tracking and accelerometers. In a first publication, an overview was given of the operational aspects of the four studies: the design, the feasibility of implementing the methods in an online panel, the willingness of respondent to participate and the difficulties encountered. In the current project, we study the compliance rates to each of these studies in more detail: e.g. how many installed the app, how many provided usable data, for how long did they participate. In addition, we analyze the covariates of participation in these studies using the respondent characteristics as measured in prior panel questionnaires.
