Risk Dimensions and Political Decisions Frame Environmental Communication: A Content Analysis of Seven U.S. Newspapers From 1970–2010

Abstract

This project examined the focus of environmental news frames used in seven American newspapers between 1970 and 2010. During this time newspapers were a primary source of news. Based on gatekeeping and agenda-setting theory, as well as source credibility, the content analysis of 2,123 articles examined the environmental topics within the articles, seven possible risk perception dimensions used in the story, and the primary source of information. The national newspapers typically reported an environmental issue paired with policy; local papers reported a single environmental issue. A Chi-square test found significant differences between national and local newspapers’ use of risk dimensions.
