The variable “issue salience” refers to visibility or prominence of a given topic or theme occurring in the news coverage and is used to explore first-level agenda-setting (McCombs & Shaw, 1972). In addition to actor salience and valence, issue salience is analyzed to describe and explore the news coverage on different events and public debates. Mostly, issue salience is measured as the number of mentioning a particular issue, topic, or theme.
Field of application/theoretical foundation:
Issue salience is analyzed using content analysis across different subfields of communication and media research, including the field of public diplomacy. In public diplomacy research, scholars measure issue salience in the context of governmental communication on their official channels online and offline or the representation of countries in social or mass media. Researchers embed the concept of issue salience primarily in agenda-setting theory (McCombs & Shaw, 1972), analyzing it as an independent variable from which to derive implications of news media coverage on audiences’ perceptions on a certain object or examining the relationship between issue salience in the media and the public agenda.
References/combination with other methods of data collection:
When it comes to analyses on issue salience and its link to public perceptions, a mixed-method study design incorporating content analysis in combination with surveys is used to validate issue salience.
