传统的议程设置模式认为，主流媒体通过引导受众关注某些问题并感知其重要性来影响公共议程。然而，在今天的数字媒体环境中，选择性增加和受众分散威胁着大众媒体的传统媒体设置力量。鉴于这一变化，需要考虑的一个重要发展是社交媒体越来越多地用于娱乐和信息。本研究探讨主流媒体是否可以通过社交媒体来影响公共议程。通过利用一个原始的，纵向的实验，我测试是否通过Facebook接触到政治信息，通过提高参与者对某些政策问题的感知重要性，产生了一个设置的效果。研究结果表明，与未显示政治信息的参与者相比，在Facebook上接触政治信息的参与者表现出与共享问题一致的问题显著性水平增加;这些影响在政治兴趣较低的参与者中最强。
Conventional models of agenda setting hold that mainstream media influence the public agenda by leading audience attention, and perceived importance, to certain issues. However, increased selectivity and audience fragmentation in today's digital media environment threaten the traditional agenda-setting power of the mass media. An important development to consider in light of this change is the growing use of social media for entertainment and information. This study investigates whether mainstream media can influence the public agenda when channeled through social media. By leveraging an original, longitudinal experiment, I test whether being exposed to political information through Facebook yields an agenda-setting effect by raising participants' perceived importance of certain policy issues. Findings show that participants exposed to political information on Facebook exhibit increased levels of issue salience consistent with the issues shared compared with participants who were not shown political information; these effects are strongest among those with low political interest.
