Modeling the Effects of Political Information Source Use and Online Expression on Young Adults’ Political Efficacy

Abstract

This online survey conducted at a public university in the Northwest (N = 434) examines the influence of political involvement, information source attention, and online political discussion on young adults’ political efficacy. A factor analysis indicated that political information sources loaded into three factors including conventional and online hard news media such as newspapers, opinion and social media such as blogs or social networking websites, and public affairs websites including government and candidate websites. A path analysis revealed significant differences in their association with online political expression and external efficacy. As an entry point in the theoretical model, involvement in public affairs positively associated with attention to political information sources, online political expression, and external political efficacy. Attention to hard news and to public affairs websites positively predicted political efficacy. Attention to online opinion and social media and to public affairs websites positively predicted online political expression.
