Individuals who experience a fear of missing out (FoMO) often rely on social media as a means to alleviate their anxiety. Self-control, defined as the ability to regulate and manage one’s behavior according to situational demands, plays a critical role in overcoming cognitive and emotional challenges. This study examines the moderating effect of self-control on the relationship between FoMO and social media addiction, highlighting how self-control can mitigate the negative psychological impacts of excessive social media use. Building upon the Improved Singular Value Decomposition (SVD) algorithm, the research investigates the underlying mechanisms linking FoMO to social media dependency and proposes an optimized model for achieving behavioral restraint. The findings underscore the potential of the enhanced SVD algorithm not only to deepen the understanding of FoMO–addiction dynamics but also to contribute to the development of strategies aimed at improving the social and psychological environment of digital platforms.
