The Healthy Context Paradox Between Bullying and Emotional Adaptation: A Moderated Mediating Effect.

Introduction: Bullying is a significant concern for young people, with studies consistently showing a link between bullying and negative emotional consequences. However, the mechanisms that underlie this association remain unclear, particularly in terms of the classroom environment. This study aimed to explore the paradoxical phenomenon between bullying victimization and emotional adaptation among junior high school students in China, using the hypothesis of the healthy context paradox. Methods: The study involved 880 students (565 girls; Mage=14.69; SD=1.407 years), and data were collected using self-reported surveys. The findings of the study, utilizing multilevel structural equation modeling (MSEM) techniques, demonstrated a cross-level moderated effect of classroom-level bullying victimization on the relationship between individual bullying victimization and emotional adaptation. Results: Specifically, the results indicated that in classrooms with higher levels of victimization, the association between individual bullying victimization and increased depressive symptoms and State&Trait anxiety was more pronounced. These findings support the "Healthy context paradox" hypothesis in the Chinese context and provide insight into the mechanisms underlying this phenomenon. Discussion: The results suggest that the classroom environment plays a crucial role in shaping the emotional consequences of bullying and that addressing classroom victimization is crucial for promoting emotional health among young people. By understanding the mechanisms that underlie the association between bullying and emotional consequences, interventions can be developed to target the underlying factors that contribute to this paradoxical phenomenon. Overall, the study provides new insights into the complex relationship between bullying and emotional health among young people, highlighting the importance of considering the classroom environment in addressing this issue.

The healthy context paradox of bullying victimization and academic adjustment among Chinese adolescents: A moderated mediation model.

Few empirical studies have specifically examined the underlying mechanisms of the "healthy context paradox" in Chinese cultural context. By constructing a moderated mediation model, the present study investigated the relationship between bullying victimization and academic adjustment, as well as the mediating effects of subjective well-being and the moderating role of classroom-level victimization. A sample of 631 adolescents (Mage = 13.75, SD = 0.74, 318 boys) were recruited from four schools in Hubei, Southern China. Results show that: (1) classroom-level victimization moderates the relationship between bullying victimization and academic adjustment. (2) Classroom-level victimization moderates the association through subjective well-being. This study confirms the healthy context paradox of bullying victimization and first reveals the mechanism of the mediating role of subjective well-being. Understanding the mechanisms that contribute to the health context paradox is crucial for developing targeted intervention strategies for individuals who experience ongoing bullying.

Long non-coding RNA in coronary artery disease: the role of PDXDC1-AS1 and SFI1-AS1.

This study investigates the interaction between long non-coding RNAs (lncRNAs) and metabolic risk factors that contribute to coronary artery disease (CAD). A total transcriptome high throughput sequencing study was conducted on peripheral blood mononuclear cells from five patients with CAD and five healthy controls. Validation assay by qRT-PCR was conducted among 270 patients and 47 controls. Finally, to evaluate the lncRNAs' diagnostic value for CAD, the Spearman correlation test and receiver operating characteristic curve (ROC) analysis were utilized. Additionally, univariate and multivariate logistic regression along with crossover analyses were conducted to identify the interaction between lncRNA and environmental risk factors. A total of 2149 of 26,027 lncRNAs identified by RNA sequencing were differentially expressed in CAD patients compared to controls. Validation by qRT-PCR showed significantly different relative expression levels for lncRNAs PDXDC1-AS1, SFI1-AS1, RP13-143G15.3, DAPK1-IT1, PPIE-AS1, and RP11-362A1.1 between the two groups (all P<0.05). The area under the ROC values of PDXDC1-AS1 and SFI1-AS1 is 0.645 (sensitivity=0.443 and specificity=0.920) and 0.629 (sensitivity=0.571 and specificity=0.909), especially. Multivariate logistic regression analyses showed that lncRNAs PDXDC1-AS1 (OR=2.285, 95%CI=1.390-3.754, p=0.001) and SFI1-AS1 (OR=1.163, 95%CI=1.163-2.264, p=0.004) were protective factors against CAD. Under the additive model, cross-over analyses demonstrated significant interactions between lncRNAs PDXDC1-AS1 and smoking in relation to CAD risk (S=3.871, 95%CI=1.140-6.599). PDXDC1-AS1 and SFI1-AS1 were sensitive and specific biomarkers for CAD and exhibited synergistic effects with certain environmental factors. These results highlighted their potential use as CAD diagnostic biomarkers for future research.

Longitudinal relationships between school assets, traditional bullying, and internet gaming disorder: the role of self-control and intentional self-regulation among Chinese adolescents.

Introduction: Although developmental assets have been proven to be enabling factors for both adolescent traditional bullying and internet gaming disorder (IGD), there is a lack of empirical evidence that has investigated the direct relationship between school assets and both of these problematic behaviors concurrently. Based on the positive youth development (PYD) perspective, the present study aimed to explore the relationship between school assets, intentional self-regulation (ISR), self-control, traditional bullying, and IGD among Chinese adolescents. Methods: A total of 742 middle school students (Mage = 13.88 years, SD = 1.99 years) were followed up to measure school assets, ISR, self-control, traditional bullying, and IGD in two waves that were separated by 5 months. Results: Structural equation modeling (SEM) indicated that T1 school assets negatively predicted T2 traditional bullying and T2 IGD. T1 self-control significantly mediated the relationships between T1 school assets and T2 traditional bullying, as well as between T1 school assets and T2 IGD. Additionally, T1 ISR strengthened the positive effect of T1 school assets on T1 self-control and further moderated the two mediating paths. Discussion: These findings show that plentiful school assets support the development of self-control and are more successful in reducing traditional bullying and IGD, particularly among students with higher ISR. As a result, schools should take measures to provide superior-quality assets for the positive development of youth, which will help to prevent and relieve traditional bullying and IGD in the school context.

The relationship between the Dark Triad and bullying among Chinese adolescents: the role of social exclusion and sense of control.

Introduction: Abundant evidence has proved the association between the Dark Triad and bullying. However, the underlying mechanisms of this relationship are still not fully understood. Based on the temporal need-threat model, three studies were designed to explore the mediating role of social exclusion and sense of control in this research. Methods: In study 1 we recruited 571 Chinese adolescents (Mage = 14.53, SD = 0.716) to participate in a cross-sectional study. And two experiments were respectively designed in Study 2 (N = 88) and Study 3 (N = 102) to verify the effects of real and cyber social exclusion on adolescent bullying behavior. Results: Study 1 showed that social exclusion and sense of control would play the serial mediating role in the relationship between the Dark Triad and bullying (except social exclusion as a mediator between the Dark Triad and cyberbullying). Study 2 and 3 showed that adolescents with high Dark Triad show lower sense of control and more bullying behavior after experiencing social exclusion. Discussion: These findings extend the research on the Dark Triad and bullying by providing a solid empirical foundation and intervention strategies to avoid bullying so that the problem can be rationally and scientifically approached.

Positive youth development attributes, mental disorder, and problematic online behaviors in adolescents: a longitudinal study amidst the COVID-19 pandemic.

Introduction: During the COVID-19 pandemic, adolescents have increasingly suffered from online problem behaviors and mental disorders. But little research has paid attention to the protective factors among adolescents. Therefore, the present study attempted to investigate the role of positive youth development (PYD) attributes in adolescents' depression, internet gaming disorder (IGD) and cyberbullying/victimization (CBV). Methods: A total of 995 Chinese adolescents (Mage = 15.97 years, SD = 0.77, 325 boys) from two public high schools in Hubei province were recruited to participate in the three-wave longitudinal study over the span of 1 year during the pandemic (Time 1: November, 2020; Time 2: May, 2021; Time 3: November, 2021). Results: T1 PYD attributes negatively predicted T2 depression and T3 online problematic behaviors. T2 depression positively predicted IGD at T3. T3 IGD significantly predicted greater involvement in T3 CBV, and vice versa. Moreover, depression and one online problem behavior mediated the relationships between PYD attributes and the other online problem behavior, separately and sequentially. Discussion: These findings demonstrated the protective role of PYD attributes in prevention of mental disorders and online problem behaviors among adolescents during the COVID-19 pandemic. Comprehensive measures should be taken to assist young people to develop more PYD attributes to promote healthy growth.

Positive youth development attributes and cyberbullying victimization among Chinese middle school students: A longitudinal moderated mediation model involving internet gaming disorder and depression.

As an extension of traditional bullying, cyberbullying emerges with the increasing popularity of the internet, and seriously affects the health of students. However, fewer studies have explored the potential influencing mechanisms of cyberbullying victimization from a positive psychology perspective. Therefore, based on the positive youth development theory, this study will explore the potential mediator and moderator in the relationship between positive youth development (PYD) attributes and cyberbullying victimization through a longitudinal design. 719 students (Mage = 15.95 years, SD = 0.76, 45.2% boy) participated in the study and completed self-report questionnaires on relevant variables. The result found that students' level of PYD significantly and negatively predicted the level of cyberbullying victimization. Meanwhile, SEM analysis showed that PYD influenced individuals' cyberbullying victimization by affecting their internet gaming disorder (IGD), while depression levels moderated the relationship between PYD and IGD. This study examines cyberbullying victimization from a positive psychology orientation, with potential prevention and intervention value.

The relationship between parental neglect and cyberbullying perpetration among Chinese adolescent: The sequential role of cyberbullying victimization and internet gaming disorder.

Cyberbullying perpetration and victimization have been common public health issues that have impaired the development of adolescent physical and mental health. Abundant research has proven associations between negative parental factors and cyberbullying perpetration. However, there is a paucity of research exploring the impact of parental neglect on cyberbullying and its internal mechanisms. Based on the parental acceptance-rejection theory (PARTheory) and the general aggression model (GAM), the present study constructs a sequential mediation model in which parental neglect is related to adolescent cyberbullying perpetration through cyberbullying victimization and internet gaming disorder (IGD). Using random cluster sampling, a total of 699 middle school students (M age = 14.18 years, SD = 1.22, and 324 boys) were recruited from five schools in three provinces on mainland China. The participants completed questionnaires regarding parental neglect, cyberbullying perpetration, cyberbullying victimization, and IGD. The results of structural equation modeling indicated that parental neglect was positively associated with cyberbullying perpetration. The mediating effects of cyberbullying victimization and IGD in this relationship are significant both individually and jointly. The current findings have important implications for enlightening families and schools to pay particular attention to adolescents' experiences of parental neglect and provide them with timely feedback and assistance. This will contribute to the prevention and reduction of adolescent involvement in cyberbullying perpetration.

Parental marital conflict and internet gaming disorder among Chinese adolescents: The multiple mediating roles of deviant peer affiliation and teacher-student relationship.

A considerable amount of evidence suggests that parental marital conflict is an important factor in adolescents' internet gaming disorder (IGD). However, the mechanism underlying this relationship remains unclear. Therefore, the purpose of this study is to explore the relationship between parental marital conflict and IGD among Chinese adolescents, and whether this relationship is mediated by deviant peer affiliation and teacher-student relationship. There were 698 Chinese adolescents that took part in the study (51.58% male; Mage = 13.52). They completed self-report questionnaires regarding perception of parental marital conflict, deviant peer affiliation, teacher-student relationship and IGD. Structural equation model (SEM) was used to examine the relationship between parental marital conflict and adolescents' IGD, as well as the mediating roles of deviant peer affiliation and teacher-student relationship. Correlation analysis showed a positive correlation between parental marital conflict, deviant peer affiliation, and IGD, as well as a negative correlation between them and teacher-student relationship. The results of the SEM showed that parental marital conflict not only predicts adolescent IGD directly, but also through the mediation effects of deviant peer affiliation and teacher-student relationship. Additionally, deviant peer affiliation and teacher-student relationship not only play an independent but also a sequential mediating effect in the relationship between parental marital conflict and IGD. The relationship between parental marital conflict and IGD is mediated by deviant peer affiliation and teacher-student relationship, which has potential prevention and intervention value for adolescent IGD.

Cyberbullying and internet gaming disorder in Chinese youth: The role of positive youth development attributes.

Introduction: As digital natives, young people enjoy the convenience and benefits of the internet but also suffer from unique developmental problems of this age, such as cyberbullying and internet gaming disorder (IGD). Research suggests that these online problem behaviors enjoy high prevalence and various negative impacts. To prevent or intervene, this study attempts to explore the association between cyberbullying and IGD and the potential protectors from the positive youth development (PYD) perspective. Methods: Through the convenience sampling method, a sample of 463 Chinese adolescents was recruited and participated in the survey. They completed a questionnaire regarding PYD attributes, cyberbullying, IGD, and demographic information. Results: After controlling adolescents' sex and age, results of regression analyses indicated that cyberbullying was positively associated with IGD; PYD attributes had negative cumulative effects on cyberbullying and IGD; and cyberbullying and IGD were negatively related to PYD attributes. Moreover, the mediating effect of PYD attributes was significant in the relationship between cyberbullying and IGD. Discussion: Specifically, it is very possible for adolescents who have experienced one online problem behavior to suffer from another one. Fortunately, positive personal attributes could effectively buffer this cascading effect. These findings may provide theoretical and practical guidance for practitioners that improving PYD attributes may be a promising approach to prevent or reduce adolescent cyberbullying and IGD.

The relationship between positive youth development and internet gaming disorder in Chinese adolescents: A moderated mediation model.

Internet gaming disorder (IGD) is a social problem that cannot be ignored. Considerable research has shown that IGD can impede the healthy physical and mental development of adolescents. Based on positive youth development theory and stage-environment fit theory, the current study explored the mediating effect of depression and the moderating effect of gender to determine the association between positive youth development (PYD) and IGD. A sample of 1970 Chinese adolescents aged 11-18 years (1021 boys, 940 girls, and 10 unidentifiable individuals) completed questionnaires related to PYD, depression, IGD, and their background information. The results revealed that PYD negatively predicted IGD. After controlling for gender and age, this study found that depression mediated the relationship between PYD and IGD. Furthermore, gender moderated the relationship between depression and IGD. Boys with depressive symptoms were more likely to indulge in IGD than girls. This research contributes to a more thorough understanding of how PYD decreases the risk of IGD. These findings suggest that cultivating PYD attributes is a promising approach to prevent or reduce depression and IGD among adolescents in mainland China.

The more developmental assets, the less internet gaming disorder? Testing the cumulative effect and longitudinal mechanism during the COVID-19 pandemic.

The COVID-19 pandemic has triggered the dramatical development and prosperity of online games, while worldwide people are suffering from it. Considering the high prevalence, serious impacts, and huge development potential of internet gaming disorder (IGD), it is extremely necessary to develop a protective model to prevent and intervene with it among young people. Based on the developmental assets theory, the present study adopted a two-wave longitudinal design to evaluate the cumulative effects of developmental assets on IGD, as well as the underlying mechanisms during this specific period. Data were collected from a sample of 1023 adolescents in Hubei province, Central China through self-report questionnaires. The results indicated that (1) developmental assets were negatively associated with adolescents' IGD concurrently and longitudinally; (2) the overall developmental assets had cumulative effects in linear patterns on adolescents' IGD, concurrently and longitudinally; and (3) internal developmental assets mediated the relationship between external developmental assets and adolescents' IGD longitudinally. Theoretically, the present study supports the developmental assets theory and expands the literature about developmental assets and IGD in younger generations. Practically, the present study provides guidance for prevention and intervention of IGD among adolescents during and after the COVID-19 pandemic. Comprehensive measures should be taken to assist in developing positive internal and external resources to promote youth thriving.

Alienation from school and cyberbullying among Chinese middle school students: A moderated mediation model involving self-esteem and emotional intelligence.

As an extension of traditional bullying behavior, cyberbullying behavior emerges with the increasing popularity of the internet, and seriously affects the health of middle school students. However, just a few studies have explored the impact of the school factor on cyberbullying and its underlying mechanisms. Therefore, the purpose of this study is to explore the potential mediator (i.e., self-esteem) and potential moderator (i.e., emotional intelligence) of the relationships between alienation from school and cyberbullying. Five hundred and seventy five Chinese middle school students participated in the study (45.74% male) and completed self-report questionnaires regarding alienation from school, cyberbullying, self-esteem, and emotional intelligence. Correlation analysis showed a positive correlation between alienation from school and cyberbullying. Mediation analysis indicated that alienation from school positively predicts individual cyberbullying, and self-esteem partly mediated the association. Meanwhile, emotional intelligence moderated the pathway from alienation from school to cyberbullying. Specifically, the effect of high alienation from school on cyberbullying was weaker for middle school students who reported high emotional intelligence. The findings of this study expose the influence of the school factor and individual factors on cyberbullying, which has potential preventive and intervention value for youth cyberbullying.

School assets and bullying in Chinese youth: A multiple mediation model of intentional self-regulation and internet gaming disorder.

Bullying is a severe social problem affecting young people all over the world. Previous studies suggested that engagement in bullying had massive effects on teenagers' physical and psychological development. It is critical and necessary to investigate the antecedents and underlying mechanisms of this phenomenon among young generations. The present study, based on the positive youth development perspective and the developmental assets theory, attempts to explore the positive factors in the school subsystem that could effectively prevent adolescents from bullying, as well as the multiple mediation effects of intentional self-regulation (ISR) and internet gaming disorder (IGD). In this study, we adopted a two-wave design and recruited a sample of 768 Chinese adolescents using a randomized cluster sampling method in the post-pandemic era. The results revealed that T1 school assets significantly and negatively predicted T2 adolescent bullying. Furthermore, T2 ISR and T2 IGD mediated the association between T1 school assets and T2 bullying separately and sequentially. Overall, school resources play a protective role in adolescent development and could effectively prevent them from negative outcomes. These current findings contribute to the literature by providing a further understanding of the direct and indirect protective effects of school assets on adolescent bullying. Moreover, practitioners could also benefit from these findings in preventing and intervening in bullying in the school subsystem.

Combine Harvester Bearing Fault-Diagnosis Method Based on SDAE-RCmvMSE.

In the fault monitoring of rolling bearings, there is always loud noise, leading to poor signal stationariness. How to accurately and efficiently identify the fault type of rolling bearings is a challenge. Based on multivariate multiscale sample entropy (mvMSE), this paper introduces the refined composite mvMSE (RCmvMSE) into the fault extraction of the rolling bearing. A rolling bearing fault-diagnosis method based on stacked auto encoder and RCmvMSE (SDAE-RCmvMSE) is proposed. In the actual environment, the fault-diagnosis method use the multichannel vibration signals of the bearing as the input of stacked denoising autoencoders (SDAEs) to filter the noise of the vibration signals. The features of denoise signals are extracted by RCmvMSE and the rolling bearing operation-state diagnosis is completed with a support-vector machine (SVM) model. The results show that in the original test data, the accuracy rates of SDAE-RCmvMSE, RCmvMSE, and commonplace features of vibration signals combined with SVM (CFVS-SVM) methods are 99.5%, 100%, and 96% respectively. In the data with noise, the accuracy rates of RCmvMSE and CFVS-SVM are 97.75% and 93.08%, respectively, but the accuracy of SDAE-RCmvMSE is still 100%.

Social Self-Efficacy and Internet Gaming Disorder Among Chinese Undergraduates: The Mediating Role of Alexithymia and the Moderating Role of Empathy.

As an increasingly serious social problem, Internet gaming disorder (IGD) of college students may be related to their social self-efficacy. However, the relationship and its internal mechanisms underlying are still unclear. The current study tested the mediating effect of alexithymia in the association between social self-efficacy and IGD, and whether this mediating process was moderated by empathy. Social Self-Efficacy Scale (PSSE), Chinese version of Internet Game Addiction Scale (IGAS-C), Toronto Alexithymia Scale (TAS-20) and Interpersonal Response Scale (IRI-C) were adopted to examine the model on 888 Chinese college students. The results indicated that social self-efficacy was significantly negatively associate with IGD. Mediation analysis illustrated that alexithymia mediated the association between social self-efficacy and IGD. Further, moderated mediation analysis manifested that the mediated effects was stronger for lower level of empathy. The conclusions corroborate and clarify the mechanisms that alexithymia mediated the association between social self-efficacy and IGD, and the mediation effects is moderated via empathy. Besides, these findings provide available references for colleges to conduct educational activities, and at the same time provide scientific suggestions for preventing IGD among undergraduates.

Cumulative Family Risk and Cyberbullying Among Chinese Adolescents: The Chain Mediating Role of School Connectedness and Cyber Victimization.

Abundant evidence has demonstrated that cumulative family risk is associated with cyberbullying. However, few studies to date have investigated how cumulative family risk links to cyberbullying. To fill in these gaps, the present study examined the mediating role of school connectedness and cyber victimization in the relation between cumulative family risk and cyberbullying. A sample of 1,804 Chinese adolescents was recruited to complete measures of cumulative family risk, cyberbullying, school connectedness, cyber victimization, and demographic variables through convenience sampling. There were 813 boys and 991 girls, aged from 13 to 18, with an average age of 16 years (SD = 1.71). Correlational analyses and SPSS macro PROCESS (Model 6) were used for major data analysis. Results indicated that cumulative family risk was positively associated with cyberbullying, and this link could be mediated by school connectedness and cyber victimization. The present study identifies the potential underlying mechanism by which cumulative family risk is associated with adolescent cyberbullying, which has important implications for theory and prevention.

Peer Victimization and Problematic Online Game Use Among Chinese Adolescents: The Dual Mediating Effect of Deviant Peer Affiliation and School Connectedness.

Abundant evidence has proved an association between peer victimization and problematic online game use (POGU). However, the underlying mechanisms of this relation are still under-investigated. Grounded in the ecological system theory, this study examined whether deviant peer affiliation (DPA) and school connectedness mediated the association between peer victimization and adolescent POGU. A sample of 698 Chinese adolescents completed questionnaires regarding peer victimization, problematic online game use, DPA, and school connectedness, of which 51.58% were boys. Path analyses indicated that peer victimization was positively associated with problematic online game use, and this link could be mediated by deviant peer affiliation and school connectedness. The findings identify the potential underlying mechanism by which peer victimization is associated with adolescent problematic online game use, which has important implications for theory and prevention.

Cumulative Family Risk and Internet Gaming Disorder Among Adolescents: A Serial Mediating Model of Personal Growth Initiative and Gratitude.

In the digital era, playing internet games enriches the entertainment forms for young generations. At the same time, it also raises some social issues, and internet gaming disorder (IGD) is one of them. Abundant studies demonstrate that IGD is harmful to individual physiological and psychological health. Therefore, it is necessary to figure out the reasons and mechanisms behind this phenomenon. Based on the ecological systems theory, the present study investigated the cumulative effect of family risks on adolescent IGD and the serial mediating effects of personal growth initiative (PGI) and gratitude in a chain mediation model. Using random cluster sampling, a sample of 600 Chinese adolescents was recruited to complete the questionnaire. Results of regression analysis suggested that cumulative family risks could positively predict IGD among adolescents. Moreover, PGI and gratitude mediated the relationship between cumulative family risk and IGD, separately, and sequentially. These findings may provide some guidance for the prevention and intervention to prevent or reduce IGD in adolescents.

Developmental Assets, Self-Control and Internet Gaming Disorder in Adolescence: Testing a Moderated Mediation Model in a Longitudinal Study.

From the perspective of positive youth development, developmental assets and self-control play critical roles in promoting adolescent development. However, their effects have not been evaluated in the current issue, internet gaming disorder (IGD). IGD is gradually becoming an important social problem among worldwide youth and has been included in the eleventh International Classification of Diseases (ICD-11). Therefore, the present study was determined to investigate the relationship between developmental assets, self-control, and IGD. A two-wave longitudinal study, with each wave spanning half a year apart, was conducted in a sample of 1023 adolescents (aging from 11 to 15, 49.36% boys) during the COVID-19 pandemic. Results of the moderated mediation model revealed that T1 developmental assets could predict less IGD at T2 directly or through T1 self-control indirectly. Furthermore, the moderating effect of gender was not significant in the mediation model. Overall, adolescents who experience more developmental assets are less likely to suffer IGD. Moreover, developmental assets are conducive to developing a higher level of self-control, which in turn contributes to preventing or intervening in IGD as well. Therefore, measures should be taken to construct developmental assets to prevent or reduce IGD during adolescence.
