Keeping in Touch with Project Participants Between Surveys: A Mailing Experiment


This working paper sheds new light on one methodological challenge encountered in studies, which is how best to keep in touch with project participants. The new paper presents one of the first rigorous tests of an approach that is commonly adopted to increase survey response when the same participants are expected to complete multiple surveys over time. Intriguingly, the findings suggest that more frequent contact between project researchers and project participants does not necessarily increase their response to surveys.
