IJERPH, Vol. 19, Pages 1222: Different Roles of Rumination and Mindfulness among Cyber-Ostracized Adolescents’ Psychological Well-Being (International Journal of Environmental Research and Public Health)

Previous research has confirmed the harmful effects of cyber-ostracism on adolescents. However, research that has investigated the effect of cyber-ostracism on adolescents’ psychological well-being and the underlying mechanisms of this influence remains scarce. Using a sample of 421 Chinese adolescents, this study examined the short-term effect of cyber-ostracism on adolescents’ psychological well-being, along with the mediating effect of rumination. Mindfulness is considered as a moderator influencing this underlying mechanism. Questionnaires regarding cyber-ostracism, rumination, and mindfulness were administered at the beginning of the spring semester. Psychological well-being was assessed three months later. The study found that cyber-ostracism significantly and negatively predicted adolescents’ psychological well-being. As shown by the mediation analysis, rumination partly mediated the effect of cyber-ostracism on adolescents’ psychological well-being. Moderated mediation analysis indicated that mindfulness played a moderating role in the relationship between cyber-ostracism and adolescents’ psychological well-being as well as the relationship between cyber-ostracism and rumination. Specifically, mindfulness would decrease the negative impact of cyber-ostracism on adolescents’ psychological well-being. This study uncovers the short-term effect of cyber-ostracism on adolescents’ psychological well-being and accentuates the underlying mechanisms of this effect, which has substantial implications for interventions and practices to reduce the detrimental effects of cyber-ostracism among adolescents.
