In the current socio-digital epoch, the intricate interplay between social media addiction and its potential ramifications on romantic relationships remains largely enigmatic, especially within specific demographic subsets. This study aims to elucidate the repercussions of social media addiction on love relationship closeness and satisfaction among Chinese undergraduates. A cohort of 583 Chinese undergraduates was meticulously analyzed, encompassing an almost equal gender distribution and spanning across diverse academic ranks and relationship durations. Utilizing the "Social Media Addiction Scale - Adult Form (SMAS-AF)" and validated scales for assessing relationship intimacy and satisfaction, the research painted a multifaceted picture. Findings revealed a high inclination towards social media addiction (X=4.20), with specific aspects of engagement demonstrating profound agreement among participants. An analytic exploration of the addiction demonstrated a pronounced influence on cognitive faculties and emotional regulation while revealing less consistent challenges in curtailing usage. In the romantic realm, while relationship closeness yielded a moderate mean score of 3.38, love relationship satisfaction signaled a moderate-to-high satisfaction degree (X=3.83). Interestingly, while gender and academic progression remained non-determinants for addiction levels, relationship length emerged as a significant variable. Correlational analyses showcased a stark negative association between social media addiction and relationship closeness (r= -.491) but, surprisingly, a positive correlation with relationship satisfaction (r= .129). Such dichotomous outcomes advocate for deeper investigation, perhaps suggesting a paradigm wherein intensified digital engagement might enhance superficial relationship contentment at the potential cost of depth and closeness.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0013/a.php" alt="Hit counter" /></p>
