Scientists’ participation in science communication and public engagement activities is considered important and a duty. However, in particular, the science-media relationship has not been studied frequently. In this paper, we present findings from interviews with both scientists and journalists which were guided by the Theory of Planned Behavior. Results show that different behavioural, normative and control beliefs underlie scientists’ and journalists’ participation in science-media interactions. Both groups are positive about science-media interactions, but scientists perceive various disadvantages in this relationship while journalists perceive mainly practical barriers. Enhancing mutual understanding and further research is suggested.
