Emerging Adults’ Views on Masspersonal Self-Disclosure and their Bridging Social Capital on Facebook

Masspersonal self-disclosure on social network sites entails new risks and benefits for bridging social capital, defined as social resources such as a connection to and investment in large and heterogeneous collectives, which are important to develop during the transition to adulthood in democratic societies. To better understand motivations and social capital consequences of masspersonal self-disclosure among emerging adults, this mixed-method study examined how U.S. college students view various topics of masspersonal self-disclosure and whether values embedded in their views contributed to their perceived bridging social capital, after accounting for their Facebook use and the diversity of their networks. A total of 208 (110 women, 95 men, 3 non-binary, Mage = 20.28) students completed online questionnaires while referring to their Facebook profiles. Qualitative analyses showed how valuing self-expression, alongside other-focused values, informed participants’ decision-making about masspersonal self-disclosure. Quantitative results showed that valuing self-expression more frequently across topics of self-disclosure predicted bridging social capital; however, the use of Facebook privacy controls and indicators of ethnic and political diversity in students’ networks did not. We discuss the importance of values in understanding emerging adults’ behaviors on social network sites, their generation of bridging social capital, and civic identity development.
