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.

This paper analyzes the influence of peer relationship on mobile phone dependence of middle school students, and probes into the chain mediating role of Self-respect and self-control. Using multi-stage random stratified cluster sampling method, 2311 middle school students in Wuling Mountain District were selected to explore the relationship between peer relationship and mobile phone dependence, Self-respect and self-control by using peer relationship scale, mobile phone dependence Scale, Self-respect scale and self-control scale. Correlation analysis showed that peer relationship, Peer relationship was positively correlated with Self-respect and self-control (r = 0.399, r = 0.291, P < 0.01), while peer relationship was negatively correlated with mobile phone dependence (r=- 0.227, P < 0.01). Mobile phone dependence was negatively correlated with Self-respect and self-control (r=- 0.409, r=- 0.629, P < 0.01). Self-respect was positively correlated with self-control (r = 0.519, P < 0.01). The structural equation model shows that Self-respect and self-control play a partial mediating role in the relationship between peer relationship and mobile phone dependence, in which the mediating effect size of Self-respect is - 0.098 (effect size 18.63%, 95%CI=- 0.140~- 0.059), and the mediating effect size of self-control is - 0.131 (effect size 24.90%, 95%CI=- 0.188~- 0.073); The chain mediating effect size of Self-respect and self-control was − 0.252 (effect size 47.91%, 95%CI = - 0.293~- 0.434). We should actively intervene the problem of mobile phone dependence of middle school students, improve Self-respect and self-control ability through good peer relationship, effectively improve their health behavior, and promote mental health.

Background and objectives Bullying victimization is strongly associated with social network site addiction among adolescents. However, the underlying mechanisms between these variables remain unclear. This study aims to explore the psychological mechanisms linking bullying victimization to social network site addiction by examining the mediating roles of depression, anxiety, stress, and inhibitory control. Methods A self-report survey was conducted among a sample of 1,005 adolescents in China. The survey included measures of bullying victimization, social network site addiction, depression, anxiety, stress, and inhibitory control. Descriptive and correlational analyses were performed, followed by the construction of a chain mediation model. Results Bullying victimization was significantly positively associated with social network site addiction. However, this relationship became non-significant when negative emotional states (depression, anxiety, stress) and inhibitory control were introduced as mediating variables. Specifically, bullying victimization significantly predicted negative emotional states and was negatively associated with inhibitory control. Negative emotional states were also negatively related to inhibitory control, while inhibitory control was negatively associated with social network site addiction. Among the negative emotional states, stress and anxiety showed a significant negative correlation with social network site addiction. Conclusion This study sheds further light on the psychological mechanisms linking bullying victimization and social network site addiction among adolescents. Depression, anxiety, stress, and inhibitory control act as mediating factors in this relationship. These findings highlight the importance of targeting these variables in understanding and developing interventions for social network site addiction 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.

The mechanical behavior of the suspenders under the coupled effects of vehicular loads and environmental factors is exceptionally complex, and the failure paths of the high-strength steel wires within the suspenders remain unclear. Consequently, there is an urgent need to establish a reliability assessment method for the fatigue system of short suspenders in existing tied-arch bridges. Taking the Fu-rong Town Bridge in China as the engineering background, this study establishes a multi-scale finite element model of the bridge and performs a dynamic response analysis of the arch bridge's suspenders using transient analysis methods. The bending-tension effects at the anchorage section of the suspenders under vehicular loads are investigated based on elementary beam theory. The bending coefficient of the shortest hanger rod in an arch bridge is 13.6 times higher than that of the longest hanger rod. Furthermore, the fatigue failure paths of the parallel steel wires within the suspenders are explored. Based on these findings, a reliability function for the fatigue system of high-strength steel wires is established using linear elastic fracture mechanics theory. The results indicate that the high-strength steel wires on the tension side of the bent short suspenders experience the maximum stress during fatigue failure, and the fatigue fracture propagates from the tension side to the compression side among the parallel steel wires.

Objective This study aims to investigate the longitudinal interplay between early adolescent bullying victimization and suicidal ideation, and to analyze the mediating role of self-efficacy in their dynamic relationship. Methods A cluster sampling method was employed to select 1,023 seventh-grade students from a middle school in an urban district of Hunan Province between March and December 2023. Three waves of data collection were conducted using questionnaires that included scales for adolescent bullying victimization, suicidal ideation (PANSI), and general self-efficacy (GSES). The cross-lagged panel model (CLPM) was utilized to explore the reciprocal relationships between early bullying victimization, suicidal ideation, and self-efficacy. Results Early adolescent bullying victimization was found to both directly and indirectly predict suicidal ideation through its impact on self-efficacy. Conversely, suicidal ideation did not directly predict the level of bullying victimization but was able to indirectly predict it through its effect on self-efficacy. Conclusion The bullying victimization in early adolescents can directly predict the level of suicidal ideation and can also indirectly influence suicidal ideation by affecting self-efficacy; Suicidal ideation does not directly predict the level of bullying victimization; rather, it can indirectly predict bullying victimization through its impact on self-efficacy.

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.
