Summary

Several studies indicate that a survey that adapts personalized design features achieves higher participation rates. A feature can be a personalized cover letter which appears more relevant and interesting for the sample member. In the spirit of adaptive design, this study seeks to establish whether it can be advantageous for participation overall to use cover letters with targeted content and whether the effect on participation of different versions of the cover letter varies in sample subgroups in order to optimize design features in future surveys.
