Effects of young adults' smartphone use for social media on communication network heterogeneity, social capital and civic engagement

Abstract

Purpose

This study examines the direct and indirect effect mechanisms of how using smartphones for social media is associated with college students' civic engagement via levels of communication network heterogeneity and social capital. In addition, this study tests whether such indirect effects mechanisms are moderated by the need to belong.

Design/methodology/approach

The study analyzes data from an online survey (N = 580) conducted at a public university. The PROCESS macro is used to examine the mediation association between mobile social media use, communication network heterogeneity, social capital, and civic engagement and the moderated mediation conditional upon need to belong.

Findings

College students who often use smartphones for social media were more likely to communicate with people who have different socio-demographic characteristics and different opinions. There was also a positive mediation mechanism between smartphone use for social media, network heterogeneity, social capital and civic engagement, which means that college students who often use mobile social media are more likely to communicate with heterogeneous others and develop a sense of social capital, which in turn led to greater levels of civic engagement. Importantly, these indirect effects of smartphone use for social media on civic engagement were stronger for those with greater levels of need to belong.

Originality/value

The findings of the current study are significant given that little is known about how young adults' mobile social media use is associated with communication network heterogeneity and civic engagement in their everyday life. The research expands the research agenda by investigating the most popular interactive communication media platforms.
