Communication Behaviors as Mediators: Examining Links Between Political Orientation, Political Communication, and Political Participation

Abstract

This study reveals the mediation process of mass and interpersonal communication between antecedent political orientation variables and the outcome response variable of political participation. It provides insight into the direct and indirect effects of political communication on political behavior using an advanced social cognitive approach. The study explores the interrelations among political orientations, communication behaviors, and political participation using the theoretical framework of the Orientation 1–Stimulus–Orientation 2–Response model (Markus & Zajonc, 1985; McLeod, Kosicki, & McLeod, 2002). A structural equation model was built and supported by 2004 American National Election Survey data. After controlling for demographic variables, both political interest and need for cognition had direct effects on political media use, whereas political interest and need to evaluate had direct effects on interpersonal political discussion. These results suggest that need for cognition and need to evaluate—2 important personality constructs—affect political communication on 2 different levels. Meanwhile, as antecedent orientation variables, political interest, political extremity, and need to evaluate all contribute to political participation. Both political media use and interpersonal discussion directly affect political participation while they also mediate the effect of the political orientation variables on political participation. Furthermore, interpersonal political discussion mediates the effect of political media use on political participation, and political media use mediates the effect of political interest and need for cognition on interpersonal political discussion.
