Experiential avoidance, depression, and difficulty identifying emotions in social network site addiction among Chinese university students: a moderated mediation model

Prevalence of depression among university students in China: a systematic review and meta-analysis

BACKGROUND

Depression among university students in China represents a critical public health challenge, with emerging evidence suggesting exacerbated risks during the COVID-19 pandemic. Despite prior regional studies, a comprehensive national analysis comparing pre-pandemic and pandemic-era prevalence, while accounting for profession-specific stressors, remains lacking. This study aims to quantify depression prevalence across Chinese universities, identify high-risk subgroups, and assess the pandemic's impact.

METHODS

A systematic search was conducted on PubMed, CNKI, Wang-fang Database, and Web of Science. The articles were cross-sectional studies focusing on the prevalence of depression among university students in China, with clearly defined criteria for diagnosing depression included. MetaXL 5.3 was used to pool the outcomes and perform a meta-analysis, assessing the prevalence of depression among university students and influential factors such as the impact of COVID-19.

RESULTS

Data from 32 cross-sectional studies (n = 93,679) on depression prevalence among students were analyzed. The prevalence estimates ranged from 12.1% to 77.1%, with a summary prevalence of 34.70% after meta-analytic pooling. Subgroup investigations based on major, sample size, geographical region, gender, and the influence of COVID-19 were conducted. Prior to the pandemic, student depression prevalence was 35.0% (95%CI, 26.9%-43.4%), which increased to 38.7% (95%CI, 33.6%-44.0%) during and after the pandemic.

DISCUSSION

This study underscores a substantial mental health burden among Chinese university students, intensified by pandemic-related disruptions. Medical students and those in high-stress regions warrant prioritized interventions. Systemic reforms in healthcare education and regionally tailored mental health policies are urgently needed. Longitudinal studies are critical to track post-pandemic recovery trajectories.

Anxiety and inhibitory control play a chain mediating role between compassion fatigue and Internet addiction disorder among nursing staff

Mental health problems among nurses are prevalent and harmful. Nurses worldwide have encountered serious mental health issues. Although fatigue has been proven to lead to substance abuse or addictive behaviors (such as internet addiction), there is a lack of sufficient data on whether there is a connection with compassion fatigue. Compassion fatigue is a common mental health problem in helping professions. Anxiety and inhibitory control have been demonstrated to be associated with internet addiction, but the mediating role between them in the state of compassion fatigue remains to be further explored. Therefore, this study aims to investigate the chain-mediating effect of anxiety and inhibitory control between compassion fatigue and internet addiction in the nurse population. From July to August 2024, a questionnaire survey was conducted using a convenience sampling method in 7 hospitals in Hunan Province, China. A total of 516 front-line clinical nurses were included, among whom 17 were male and 499 were female. Subjective data on compassion fatigue, internet addiction, anxiety, and inhibitory control were collected and analyzed. SPSS 26.0 and its PROCESS macro-plugin were used for data analysis. After controlling for age and gender, compassion fatigue was found to be a significant predictor of internet addiction (β = 0.40, P < 0.001). However, when anxiety and inhibitory control were added, the prediction of compassion fatigue on internet addiction in the nurse population remained significant (β = 0.18, P < 0.001). Eventually, the research results show that compassion fatigue can predict internet addiction through anxiety and inhibitory control. It is recommended that nursing managers provide appropriate emotional interventions for nurses with compassion fatigue or adjust the shift-scheduling and leave system to prevent the occurrence of internet addiction.

Gender mediates the mediating effect of psychological capital between physical activity and depressive symptoms among adolescents

Adolescents develop rapidly, are sensitive to external environmental pressure, and are prone to depression symptoms. Physical activity has been identified as a protective factor for depressive symptoms. Psychological capital is strongly associated with depressive symptoms, and gender has been identified as a potential protective factor. For adolescents in early adolescence, the complex relationship between these factors needs further study. The aim of this study was to explore the mediating role of psychological capital between depressive symptoms and physical activity in adolescents, and the moderating role of gender between the two. Physical activity, depressive symptoms and psychological capital were measured by Physical Activity Rating Scale (par-3), Central Depression Scale (CES-D) and Psychological Capital Scale (PCQAS) in 1146 adolescents. The proposed relationships were tested using models 4 and 14 of the structural equation model, respectively, for mediating and regulating effects. Physical activity was negatively correlated with depressive symptoms and positively correlated with psychological capital. Psychological capital was negatively correlated with depressive symptoms and mediated the relationship between physical activity and depressive symptoms. Gender effectively modulates the latter half of the mediated model pathway. In adolescents, especially girls, depression symptoms can be alleviated and prevented by increasing daily physical activity and positive psychological capital reserve.

Child psychological maltreatment, depression, psychological inflexibility and difficulty in identifying feelings, a moderated mediation model

Child psychological maltreatment has a strong relationship with college students' depression. However, the potential mediating and moderating variables between the two need further exploration. This study collected subjective data of college students from two universities in China through a cross-sectional survey, including variables such as child psychological maltreatment, psychological inflexibility, difficulty in identifying feelings, and depression. Through correlation analysis, a mediation model and a moderated mediation model were constructed to explore the interrelationships among the variables.The research results show that there is a significant positive correlation between child psychological maltreatment, psychological inflexibility, difficulty in identifying feelings, and college students' depression. Moreover, psychological inflexibility plays a mediating role between child psychological maltreatment and college students' depression, while difficulty in identifying feelings significantly moderates the relationship between child psychological maltreatment and college students' depression. This study reveals the significant associations among child psychological maltreatment, psychological inflexibility, difficulty in identifying feelings, and college students' depression. These findings remind us to pay attention to the potential mediating role of psychological inflexibility and the moderating role of difficulty in identifying feelings when exploring the relationship between child psychological maltreatment and college students' depression. These results provide a new perspective for understanding the psychological mechanism of depression and offer potential targets for prevention and intervention.

The Chain Mediating Effect of Anxiety and Inhibitory Control and the Moderating Effect of Physical Activity Between Bullying Victimization and Internet Addiction in Chinese Adolescents

This study aimed to investigate the chain mediating roles of anxiety and inhibitory control in the relationship between bullying victimization and internet addiction among Chinese adolescents, as well as the moderating effect of physical activity. A cross-sectional design was employed, sampling 1,585 adolescents from 5 provinces in China during February-March 2024. Data on bullying victimization, internet addiction, anxiety, inhibitory control, and physical activity were collected and analyzed using a moderated chain mediation model. The data suggest that bullying victimization is associated with internet addiction, and this association is also mediated by anxiety and inhibitory control. Furthermore, physical activity was found to significantly moderate the relationship between anxiety and inhibitory control. This study contributes to the understanding of how bullying victimization, anxiety, and inhibitory control are interrelated in the context of internet addiction development, with physical activity influencing this interplay. It highlights the potential of physical activity as a factor in mitigating the impact of bullying and its association with internet addiction.
