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.

Due to the diversity of global languages and the influence of local practices and individual histories, it is common and controllable for individuals to speak with accents. With the emergence of online medical consultations as a new service model and the diversity of accents, doctors on digital platforms can choose to communicate using standard or nonstandard (local) accents. However, we lack a thorough understanding of how a doctor's accent characteristics influence patient satisfaction in online medical scenarios. In the context of China's online medical services, this study investigates how accent standardness and similarity influence patient satisfaction in online medical scenarios with information asymmetry. Through two complementary experiments, we first examine how accent standardness interacts with professional capital to influence patient satisfaction through perceived competence (Study 1), and then validate Study 1's findings in different experimental scenarios while exploring how accent similarity interacts with hometown information disclosure to influence patient satisfaction through perceived warmth (Study 2). we find that accent standardness is more important, yielding higher patient satisfaction. It positively impacts patient satisfaction and compliance intention, mediated by perceived competence and moderated by professional capital. Local accent similarity also positively influences patient satisfaction, mediated by perceived warmth and enhanced by patient hometown information disclosure. These findings provide valuable insights for effective online medical communication in this evolving healthcare landscape.
