Swiss Household Panel Mode Experiment, 2017-2018
In preparation for the launch of its third refreshment sample, I was invited by Marieke Voorpostel, Robin Tillman and Oliver Lipps at FORS to advise on the design of a large-scale experiment designed to test alternative waves of using web-based data collection at the recruitment phase of a longitudinal survey, assessing effects on wave 1 participation and drop out at wave 2, and sample composition. The study compared a fully-online design with a mixed mode protocol, combining telephone interviews with household reference persons with web-based questionnaires for individual household members. The study was also designed to assess mode effects on measurement.

LIVES Cohort Study Mode Preferences Study, 2019
In collaboration with LIVES, the Swiss Centre of Expertise in Life Course Research and the FORS Swiss Household Panel Survey Team, I included additional questions to investigate data collection mode preferences among participants in the LIVES Cohort Study. The aim was to investigate the feasibility of switching to online methods in future waves, and in particular, participation on smartphones.
