Abstract：Objective To investigate the impact of university students’ social anxiety on smartphone social media addiction, and explore the mediating role of loneliness. Methods A random sampling method was used to conduct a questionnaire survey on 494 students from a university in Shandong Province. The Bergen social media addiction scale, social anxiety subscale of the self-awareness scale, and UCLA loneliness scale were used for measurement. A total of 463 valid questionnaires were collected. The relevant data were statistically analyzed. Results Social anxiety was significantly positively correlated with loneliness and smartphone social media addiction, as well as their various dimensions. Loneliness was significantly positively correlated with smartphone social media addiction and most of its dimensions. The results of the mediation regression analysis showed that social anxiety had a significant direct predictive effect on smartphone social media addiction（β=0.35, P<0.001）, and the predictive effect remained significant after adding the mediator variable of loneliness（β=0.30, P<0.001）. The predictive effect of social anxiety on loneliness was significant（β=0.44, P<0.001）, and the predictive effect of loneliness on smartphone social media addiction was significant（β=0.13, P<0.01）. The mediation effect test results of Bootstrap sampling method showed that social anxiety had a significant direct effect onsmartphone social media addiction, with an effect size of 0.99（95% CI: 0.66-1.31）, accounting for 84.03% of the total effect size. The mediating effect of loneliness between social anxiety and smartphone social media addiction was significant, with an effect size of 0.19（95% CI: 0.03-0.35）, accounting for 15.97 % of the total effect size. Conclusion Social anxiety directly affects smartphone social media addiction tendency and has an indirect effect on this tendency through the mediation effect of loneliness.
