How issues are portrayed in mass media and how this influences the political attitudes of the audience are central questions in communication research. This book provides an answer from the perspective of the framing approach. Based on a theoretical and methodological analysis, the author conducts a comprehensive study on the topic of unemployment, linking data from a content analysis with a panel survey of the recipients. The results show that media reporting on unemployment affects the actual political attitudes of the recipients. However, this influence depends on the type of attitude formation. By demonstrating such framing effects with representative field data, this work not only fills a gap in existing framing research but also provides methodological and theoretical impulses.
