An Index of Mediatisation: Comparing Interest Groups’ Political Communication Behaviour

Abstract

This article investigates the political communication behaviour of interest groups. First, by proposing indices to capture the degree to which mass media have become central for political communication (media logic of communication), and the degree to which conventional strategies aimed at politicians directly govern groups’ communication behaviour (political logic of communication). Based on these two indices, the article then proposes an overall index of mediatisation. Second, the article tests three hypotheses regarding the use of the media logic, the political logic, and the mediatisation of interest groups, and finds that group type, resources, and the level of competition all play a role for how strongly interest groups are mediatized. Thus, this article contributes to the scarce empirical research on mediatisation by a) proposing a way to operationalise this concept which can be adjusted using a different set of variables, but can also be applied for different political actors, and b) by showing the usefulness of the constructed indices in an empirical example for Swiss and German interest groups.
