Mediating Roles of News Curation and News Elaboration in the Relationship between Social Media Use for News and Political Knowledge

摘要

Social media have opened up new possibilities for news engagement, and one of the important possibilities is news curation, which is defined as the reconstructing, reformulating, repurposing, reframing and sharing of news through social media. Focusing on this news curation concept, this study extends the Cognitive Mediation Model and the Communication Mediation Model (O-S-R-O-R) to the social media context. Drawing on a national survey of 1,135 South Korean adults, the present study finds that news elaboration and news curation are positively related to political knowledge and mediate the association between social media use for news and political knowledge.
