Abstract
This study examines how three different motivations for using an SNS (i.e., self-expression, belonging, and memory archiving) influence multi-facets of privacy boundary management on the platform mediated by self-extension to it. In recognition of the fact that information management on SNSs often goes beyond the “disclosure-withdrawal” dichotomy, the study investigates the relationships between the three SNS motives and privacy boundary management strategies (i.e., collective boundary and boundary turbulence management). An online survey with Facebook users (N = 305) finds that the three Facebook motivations are positively correlated to users’ self-extension to Facebook. The motivations for using Facebook are positively associated with the management of different layers of privacy boundaries (i.e., basic, sensitive, and highly sensitive), when Facebook self-extension is mediated. In addition, the three motives have indirect associations with potential boundary turbulence management mediated by Facebook self-extension. Extending the classic idea that privacy is deeply rooted in the self, the study demonstrates that perceiving an SNS as part of the self-system constitutes a significant underlying psychological factor that explains the linkage between motives for using SNSs and privacy management.
Highlights
Following advances in data-mining technology and the increased popularity of social media, personal information management on social networking sites (SNSs) has become a critically important yet complex issue (Wisniewski et al, 2015)
Regarding the indirect effects (H2), the results revealed that all 3 Facebook motivations were found to be indirectly associated with Information Disclosure Index (IDI) of basic, sensitive, and highly sensitive information when Facebook self-extension mediated
The results showed that Facebook self-extension promotes active monitoring of information flows online, it is almost impossible for users to perfectly control the flow of information once that information is already shared with others on social media
Summary
Following advances in data-mining technology and the increased popularity of social media, personal information management on social networking sites (SNSs) has become a critically important yet complex issue (Wisniewski et al, 2015). Among the various SNSs, Facebook is one of the most popular SNSs in the world (Datareportal, 2021). It has various privacyrelated issues manifested through such cases as accidental exposure of 6 million users’ contact information in 2011 and the Cambridge Analytica data breach in 2018 (Ivanova, 2018). Users still share a large amount of personal information on SNSs (Osatuyi et al, 2018; TsayVogel et al, 2018). A longitudinal study showed that the negative relationship between Facebook users’ privacy concerns and their disclosure of personal information on Facebook has weakened
