This study aims to explore the moderating effect of trust on the relationship between social media engagement, relationship benefits, and social relationships, utilizing an innovative framework grounded in social exchange theory. Employing a quantitative analysis with structural equation modeling (SEM), using a questionnaire distributed to a sample of 493 Jordanian youth, the results unveil a positive correlation between social media engagement and social relationships, with trust emerging as a crucial moderator in this dynamic. Trust positively moderates the connection between social media engagement and social relationships. This research sheds light on the pivotal role of trust in shaping social relationships on social media platforms. However, the interaction between trust and relationship benefits does not significantly impact social relationships.
