|名稱||They support, so we talk: the effects of other users on self-disclosure on social networking sites
|摘要||Purpose – Social networking sites (SNSs) have significantly influenced people’s lives and changed their
behavior. Although previous research has explored self-disclosure in virtual communities, little is known about
the impact of other users, particularly their online social support, on self-disclosure. The aim of this study is to
explore how online social support dimensions (i.e., emotional, informational, esteem, instrumental and network
support) influence people’s self-disclosure, which in turn affects their commitment to SNSs.
Design/methodology/approach – Based on social exchange theory, this study proposes a research model
that explores the role of other users on self-disclosure. This study collects data from a sample of 558
respondents and applies the structural equation modeling technique to test the research model.
Findings – The findings show that users are motivated to disclose information and commit to a specific SNS
because of the supportive climate. Results also show that self-disclosure mediates the effect of online social
support on users’ commitment to SNSs.
Originality/value – This study focuses on the influence of other users’ roles on self-disclosure on SNSs,
extending the application of social exchange theory.

|名稱||Member lock-in and knowledge break-out in SNS groups: integrating the “pull-in”, “push-back”, and “mooring” effects
Social networking site (SNS) group provides a new cyberspace for users to share knowledge. As competition intensifies and recruiting new members becomes more difficult, SNS groups need to devote their strategic efforts to encouraging members’ contributions. However, prior research has seldom touched this issue from the “online switching barrier” perspective. We develop and test a structural equation model incorporating pull-in (group-member and member-member relationship quality), push-back (alternative unattractiveness), and mooring (switching cost) effects, which subsequently affect members’ knowledge contribution behavior (knowledge sharing and knowledge co-creating) through the mediating role of self-development and pro-social motivation for engagement. Results based on 382-respondent survey data show that pull-in and push-back factors facilitate members’ contributing motivations, which in turn lead to contribution behavior. The mooring effect which is reflective of different levels of switching costs moderates the effects of pull-in/push-back on self-development and pro-social motivation. The findings provide academic insights for scholars and marketing implications for practitioners in leveraging lock-in effect in SNS groups.
