The mediating role of knowledge and efficacy in the effects of communication on political participation

This study explicates the indirect process through which news media use influences political participation. Specifically, it investigates the role of political knowledge and efficacy as mediators between communication and online/offline political participation within the framework of an O-S-R-O-R (Orientation-Stimulus-Reasoning-Orientation-Response) model of communication effects. Results from structural equation modeling analysis support the idea that political knowledge and efficacy function as significant mediators. In addition, results expound the increasing importance of the Internet in facilitating political participation. Implications of findings, limitations of this study, and suggestions for future research are discussed.
