Grounded in social penetration theory and social capital theory, this study aims to investigate how social media self-disclosure influences bridging and bonding online social capital, and how these in turn affect users' loneliness and online interpersonal trust. A moderated mediation model was proposed and tested using cross-sectional survey data collected from 1519 Chinese netizens. Regression analyses revealed that self-disclosure on social media positively predicted both types of online social capital. Bridging social capital mediated the relationship between self-disclosure and reduced loneliness, while bonding social capital mediated the link between self-disclosure and enhanced online interpersonal trust. Moreover, agreeableness moderated the effect of self-disclosure on bonding social capital. These findings enrich the theoretical understanding of online self-disclosure and reveal the underlying motivations for users to disclose personal information on social media, even in the context of the privacy paradox.
基于社会渗透理论和社会资本理论，本研究旨在探讨社交媒体自我表露如何影响在线的桥梁型和纽带型社会资本，以及这些资本又如何反过来影响用户的孤独感和在线人际信任。本研究提出了一个有调节的中介模型，并使用从1519名中国网民收集的横断面调查数据进行了检验。回归分析表明，社交媒体上的自我表露对两种类型的在线社会资本均有正向预测作用。桥梁型社会资本在自我表露与孤独感减轻之间起中介作用，而纽带型社会资本在自我表露与在线人际信任增强之间起中介作用。此外，宜人性调节了自我表露对纽带型社会资本的影响。这些发现丰富了对在线自我表露的理论理解，并揭示了用户在社交媒体上披露个人信息的潜在动机，即使是在隐私悖论的背景下。
