Coverage of Alzheimer's disease from 1984 to 2008 in television news and information talk shows in the United States: an analysis of news framing.

摘要

This study examined 1371 TV news transcripts on Alzheimer's disease (AD) from 6 TV news networks during a 25-year period (1984-2008) employing the news framing perspective. Issues, sources, and episodic-thematic news about AD derived from the news framing perspective were analyzed. Results revealed that AD issues, such as treatments, personal stories, celebrities, and policy increased over time, whereas other issues including facts, causes, signs, and diagnosis received relatively limited news attention. Correlation analyses among episodic-thematic frames, issues, and sources found that episodic-thematic frames were positively linked with such issues as personal stories and policy and sources, including patients and politicians. The results suggest that although TV news covers episodic frames more than thematic ones, both frames can interact with each other to influence personal and social news about AD. Particularly, the role of celebrity affecting AD news at both individual and social levels is salient.
