Clinical Trial Summary
The aim of this study is to examine the potential for animation movies to improve response
rates and sample composition in an embedded randomized controlled trial in the Danish
National Health Survey 2021. The overall research question is whether cover letters including
an animation movie can perform better than generic letters.
Description:
The aim of this study is to examine the potential of animation videos to improve response
rates and sample composition in an embedded randomized controlled trial in the Danish
National Health Survey 2021 (DNHS-2021). The overall research question is whether digital
cover letters including an animation video can perform better than digital letters without
animations. The proposition is that such letters should increase the willingness of some
sample members to participate by means of increased motivation and reduced complexity, and
that this will be reflected in higher response rates. In addition to examining whether it can
be advantageous for overall response rates to use cover letters including animation videos,
this study also examines the effect of different versions of the animation videos across
sample subgroups in order to identify how to best target potential non-respondents in future
surveys.
