Although the World Health Organization (WHO) has issued guidelines for managing to contain, mitigate, and limit of the COVID-19. However, it is more essential to highlight the urgency and importance of evaluating social functioning and mental health status during the pandemic. College students have experienced serious problems and have had to overcome many negative situations brought about by the pandemic. Accordingly, the present study intended to use Chinese college students as sample to examine the positive adoption and changes during the ongoing COVID-19. Guided by literatures in this filed, we explored the internal mechanism of post-traumatic growth affecting psychological resilience, and considered about mediation roles of positive coping styles and cognitive reappraisal. A total of 463 college students from universities in China effectively completed online questionnaires. The result indicated that these four variables were positively correlated with each other (ps < 0.001). More importantly, our findings proved a direct and positive effect on psychological resilience. Positive coping styles and cognitive reappraisal, respectively, mediated the relationship between post-traumatic growth and psychological resilience. Over all, the hypothesized serial model conclusively fits the data: students with high-level post-traumatic growth tended to report increased use of positive coping strategies, which further facilitated their cognitive reappraisal, and subsequently, promoted their psychological resilience. The findings obtained in this study will provide a theoretical basis and possible viable strategies for both targeted crisis intervention and psychological trauma recovery plans.

Objective: This study aims to explore the direct effects of extraversion and neuroticism on college freshmen's depressive symptoms and their indirect effects via social support under the background of COVID-19.Method: A total of 3,563 college freshmen were surveyed using the extraversion and neuroticism scales of the Chinese version of the Eysenck Personality Questionnaire (EPQ), the Chinese version of the Beck Depression Inventory-II (BDI-II), and the Social Support Rating Scale (SSRS). Partial correlation analyses and regression analyses were used.Results: (1) Extraversion had a significant and negative predictive effect on depressive symptoms, while neuroticism positively predicted depressive symptoms. The interaction effect between extraversion and neuroticism on depressive symptoms was also significant. Neuroticism had a greater impact on depressive symptoms in college freshmen with low levels of extraversion. (2) Furthermore, social support partially mediated the relationships between extraversion and depressive symptoms, and neuroticism and depressive symptoms.Conclusions: Extraversion and neuroticism can directly affect college freshmen' s depressive symptoms, and have indirect effects via the mediating role of social support. Additionally, extraversion interacts with neuroticism, and extraversion plays a protective role in the effect of neuroticism on depressive symptoms. These findings help identify college freshmen at high risk of depression and design effective prevention or intervention measures for them.

In the digital age, the escalating accessibility of the Internet to younger populations prompts significant concerns about its potential behavioral repercussions. The objective of this research is to investigate the connection between Internet use and externalizing problem behaviors in early adolescents. A total of 1155 Chinese early adolescents, ranging in age from 11 to 14 years, participated by completing an anonymous self-report questionnaire. The findings reveal that: (1) there is a positive correlation between the extent of Internet use and the prevalence of externalizing problem behaviors, suggesting a potential risk factor inherent in unregulated digital exposure; (2) both self-education expectations and peer relationships mediate the link between Internet use and externalizing problem behaviors, indicating that educational aspirations and social interactions play a pivotal role in mediating this impact; (3) Internet use indirectly influences externalizing problem behaviors through the sequential mediation of self-education expectations and peer relationships, outlining a complex interplay that influences behavioral outcomes; and (4) the influence of Internet use on externalizing problem behaviors shows notable differences based on gender and geographical location, with a greater adverse impact observed in males than in females and in rural settings compared to urban areas. These findings underscore the urgent need for bespoke strategies to mitigate the negative influences of Internet use on youth, tailored to address the specific challenges faced by different demographic groups. The study not only extends the current understanding of digital media’s impact on adolescent behavior but also catalyzes policy discussions aimed at fostering healthier digital environments for the younger generation.

Problematic mobile phone use (PMPU) is a significant concern, particularly among adolescents. Accumulating evidence indicates that early traumatic events, such as childhood emotional abuse (CEA), are predisposing factors for adolescent PMPU. The primary objective of the current study was to examine the relationship between childhood emotional abuse (CEA) and problematic mobile phone use (PMPU) among adolescents, as well as to explore the potential mediating roles of rumination and symptoms of depression. Data were collected from Chinese senior high school students (N = 489, 44.79% males and 55.21% females, Mage = 16.92 years, SD = 0.67) who completed the measures of CEA, rumination, depression symptoms, and PMPU. The results revealed that (1) CEA did not have a direct effect on PMPU among adolescents; (2) CEA was associated with PMPU through rumination and depression symptoms, separately; (3) CEA was linked to PMPU via a sequential pathway from rumination to depression symptoms. The present study has unveiled the roles of CEA, rumination, and depression symptoms in the development of PMPU among adolescents. More precisely, rumination and depression symptoms serve indirect roles in the relationship between CEA and adolescent PMPU.
