The mediating role of political talk and political efficacy in the effects of news use on expressive and collective participation

This study examines how media use for news can relate to expressive and collective participation through the mediating role of political talk and internal and external political efficacy. Based on two cross-sectional analyses and one autoregressive analyses of the data obtained from a two-wave panel survey during the 2012 presidential campaign in South Korea, this study finds that political talk and internal political efficacy mediate the association between news attention and expressive participation, while external political efficacy does not. Political talk and internal political efficacy jointly mediate the impact of news attention on expressive participation. The analysis also reveals that social media news attention and internal political efficacy play a bigger role in connecting news attention and political participation than traditional news attention, external political efficacy, and political talk.
