The Effect of Self-Disclosure Behaviors in Social Media on Peer Dynamics among University Students

With the advancement of technology, self-disclosure has become a trend on social media platforms. Most previous studies have mainly focused on the breadth and depth of the disclosure, leaving gaps in its extension. Thus, this study aims to examine the effects of self-disclosure behaviors (breadth, depth, appropriateness, and intent) on the peer dynamics among university students by using Social Penetration Theory (SPT) as the underpinning theoretical framework. The study applied a quantitative survey method and gathered 175 valid respondents. The results showed that depth, appropriateness, and intent have a positive and significant impact on the peer dynamics; however, breath does not. This study contributed to the interpersonal communication scholarship by testing the extension of the SPT, which includes appropriateness and intent. The study provides implications for the educator, social media users, policy makers, and NGOs on advocating a safe digital environment and online interaction for self-disclosure on relationship maintenance and well-being.
