Building on channel complementarity theory and media-system dependency theory, this study explores the impact of conflict-oriented news coverage of health issues on information seeking online. Using Google search data as a measure of behavior, we demonstrate that controversial news coverage of the U.S. Preventive Services Task Force's November 2009 recommendations for changes in breast cancer screening guidelines strongly predicted the volume of same-day online searches for information about mammograms. We also found that this relationship did not exist 1 year prior to the coverage, during which mammography news coverage did not focus on the guideline controversy, suggesting that the controversy frame may have driven search behavior. We discuss the implications of these results for health communication scholars and practitioners.
基于渠道互补理论和媒体系统依赖理论，本研究探讨了对健康问题的冲突导向新闻报道对在线信息搜索的影响。本研究使用谷歌搜索数据作为行为的衡量标准，证明了美国预防服务工作组（U.S. Preventive Services Task Force）2009 年 11 月关于乳腺癌筛查指南变更的建议的有争议的新闻报道强烈预测了当天在线搜索有关乳房 X 光检查信息的数量。我们还发现，在报道前一年，这种关系并不存在，在此期间，乳房 X 光检查的新闻报道并没有集中在指南争议上，这表明争议框架可能推动了搜索行为。我们讨论了这些结果对健康传播学者和实践者的意义。
