A meta-analysis on the relation between peer victimization and adolescent non-suicidal self-injury

The Relationship Between Self-Esteem and Mobile Phone Addiction Among Mainland Chinese Adolescents: A Meta-Analysis

In recent years, the problem of mobile phone addiction (MPA) has become increasingly serious among mainland Chinese adolescents. Studies have found that self-esteem may be related to MPA, but the conclusions are inconsistent. Consequently, this meta-analysis aims to explore the real relationship between self-esteem and MPA, and analyze the moderator variables. The relevant studies used in meta-analysis were obtained by searching China National Knowledge Infrastructure (CNKI), Wan Fang Data, Chongqing VIP Information Co., Ltd. (VIP), PubMed, Web of Science, Scopus, Medline and Embase. Then articles were screened and coded, and statistical analysis was carried out by Stata 16.0 software. A total of 45,765 participants from 64 articles were included in the research. Meta-analysis showed that there was a moderate negative correlation between self-esteem and MPA(r = -.25, 95%CI = -.29, -.21). Subgroup analysis and meta-regression analysis showed that the age and publication time can significantly moderate the relationship between self-esteem and MPA, but MPA measurement instrument, gender, region and publication type have no significant moderating effect. The current meta-analysis provided solid evidence that self-esteem was negatively correlated with MPA. Longitudinal studies are needed to clarify the causality between them, so as to make more specific practice and policy recommendations.

The impacts of latent profiles and transitions of stresses on adolescent mental health: A person-centred analysis

Research has demonstrated robust links between adolescent stress and serious psychological problems. The current study aimed to identify latent stress profiles of 1510 adolescents (59.7% females; Mage  = 16.77 years, SD = 0.86) based on five stresses (parental stresses, family environment stresses, academic stresses, teacher stresses, and peer stresses) at three time points (T1/2/3). Moreover, this study would investigate the transition patterns of these profiles over time and examine the associations between the profiles and adverse psychological symptoms (e.g., anxiety, depression, nonsuicidal self-injury [NSSI], and suicidal ideation). Three latent stress profiles were identified, including High-stress profile, Medium-stress profile, and Low-stress profile. The three profiles were significantly different on the levels of T1/2/3 anxiety, depression, NSSI, and suicidal ideation. The profile memberships remained relatively stable across three time points. Notably, the present study found gender differences, with boys were more likely to be in the High-stress profile and to transition from the Medium- to the High-stress profile, compared to girls. Furthermore, left-behind adolescents were more likely to be in the High-stress profile than non-left-behind adolescents. The findings highlight the importance of adopting 'this-approach-fits-this-profile' interventions for adolescents. Parents and teachers are advised to adopt different strategies for girls and boys.

Impacts of difficulties with emotion regulation on the longitudinal relationship between peer victimization and changes in adolescent nonsuicidal self-injury

INTRODUCTION

Research has found that peer victimization is associated with adolescent nonsuicidal self-injury (NSSI) behavior; however, most of these studies ignored the association between these constructs at the within-person level. Additionally, the association between peer victimization and NSSI may vary among adolescents with different personal characteristics. With a longitudinal design, this study investigated whether and how emotion regulation (ER) difficulties moderate the relationship between peer victimization and changes in NSSI, with particular attention given to the unique moderating role of different dimensions of ER difficulties.

METHODS

The study sample comprised 3,561 adolescents aged between 10 and 17 years old (Mage  = 13.22, SD = 0.85; 56.9% males). Self-report assessments were administered in December 2021 and June 2022 in Shanxi province, China.

RESULTS

The latent change score model showed that the adolescent NSSI increased during our assessments, with peer victimization as a significant predictor. ER difficulties moderated the association between peer victimization and NSSI changes, but interestingly, in an unexpected pattern. Specifically, peer victimization significantly predicted NSSI changes among adolescents with low ER difficulties but not for those with high ER difficulties. Moreover, among the multiple dimensions of ER difficulties, only nonacceptance of emotional responses and limited access to emotion regulation strategies interacted with peer victimization to predict NSSI changes and showed interaction patterns similar to those at the overall level of ER difficulties.

CONCLUSIONS

The current study revealed the moderating role of ER difficulties in the relationship between peer victimization and changes in NSSI. These findings provide intervention implications for adolescents who engage in NSSI.

Peer victimization and non-suicidal self-injury among high school students: the mediating role of social anxiety, mobile phone addiction, and sex differences

BACKGROUND

Peer victimization (PV) is one of the major causes of non-suicidal self-injury. Non-suicidal self-injury (NSSI), peer victimization, social anxiety, and mobile phone addiction are significantly related; however, the interaction mechanism and effect of sex differences remain to be determined.

OBJECTIVE

Herein, we investigated the relationship between peer victimization and NSSI among Chinese high school students. We also explored the chain mediating roles of social anxiety and mobile phone addiction and the regulatory role of sex. The findings of this study provide insights for theoretical interventions based on internal mechanisms.

METHOD

A self-reported survey of 14,666 high school students from Sichuan County was conducted using a peer victimization scale, NSSI scale, social anxiety scale, and mobile phone addiction scale. A self-administered questionnaire was used to capture sociodemographic information.

RESULTS

Peer victimization, social anxiety, and mobile phone addiction were positively correlated with NSSI. Peer victimization had significant direct predictive effects on NSSI (95% CI: 0.341, 0.385) and significant indirect predictive effects on NSSI through social anxiety (95% CI: 0.008, 0.019) or mobile phone addiction (95% CI: 0.036, 0.053). Peer victimization had significant indirect predictive effects on NSSI through social anxiety as well as mobile phone addiction (95% CI: 0.009, 0.014). The first stage (predicting the effect of peer victimization on NSSI) and the third stage (predicting the effect of mobile phone addiction on NSSI) were both moderated by sex.

CONCLUSIONS

Peer victimization could directly predict NSSI and indirectly predict NSSI through social anxiety and mobile phone addiction. Thus, social anxiety and mobile phone addiction exhibited chain mediating effects between peer victimization and NSSI in high school students; moreover, sex might be involved in the regulation of the mediation process.

Prevalence of engagement and frequency of non-suicidal self-injury behaviors in adolescence: an investigation of the longitudinal course and the role of temperamental effortful control

Non-suicidal self-injury (NSSI) is among the most frequent maladaptive behaviors reported in adolescence, with prevalence rates around 18-22% in community samples worldwide. The onset of NSSI typically occurs between early and middle adolescence, with a peak during middle adolescence (14-15 years) and a subsequent decline during late adolescence. This study investigated the growth curves of NSSI across four years during adolescence, analyzing simultaneously the probability of engagement in NSSI at least once (i.e., prevalence) and the frequency of engagement once initiated (i.e., severity). Furthermore, the study examined the predicting role of effortful control on NSSI over time (time-varying effects), net of other key risk factors for NSSI, such as anxiety-depression and bullying victimization. A sample of 430 Italian adolescents enrolled in Grade 9 at baseline was involved in the study. Based on the Latent Growth Curve Zero-inflated Poisson methodology, the results indicated a negative quadratic trend of both NSSI prevalence, with an increase between T1 and T3 followed by a decrease in the subsequent wave, and NSSI frequency once initiated, with a peak at T2 followed by a decline over time. The results also showed that adolescents who reported low effortful control abilities had a heightened probability of involvement in NSSI at each time point, whereas no significant association was found with NSSI frequency once initiated. Findings from this study offer important insights into the developmental course of NSSI and point out the need for future in-depth investigations of the mechanisms that might underlie NSSI prevalence and severity throughout adolescence.

Impact of the COVID-19 and psychological risk factors on non-suicidal self-injury behavior among high school students: a one-year follow-up study

OBJECTIVES

Non-suicidal self-injury (NSSI) behavior is a severe public health issue in adolescents. This study investigated the possible impact of the coronavirus disease 2019 (COVID-19) and analyzed psychological risk factors on adolescent NSSI.

METHODS

A one-year follow-up study was conducted in September 2019 (Time 1) and September 2020 (Time 2) among 3588 high school students. The completed follow-up participants (N = 2527) were classified into no NSSI (negative at both time points), emerging NSSI (negative at Time 1 but positive at Time 2), and sustained NSSI (positive at both time points) subgroups according to their NSSI behaviors before and during the COVID-19 pandemic. Perceived family functioning, perceived school climate, negative life events, personality traits (neuroticism, impulsivity, and self-control) were assessed using self-report scales.

RESULTS

The data indicated an increase (10.3%) in the incidence of NSSI. Compared to no NSSI subjects, the emerging NSSI and sustained NSSI subgroups had lower perceived family functioning, higher neuroticism, higher impulse-system but lower self-control scores, and more negative life events. Logistic regressions revealed that after controlling for demographics, neuroticism and impulse-system levels at Time 1 positively predicted emerging NSSI behavior, and similarly, higher neuroticism and impulsivity and lower self-control at Time 1 predicted sustained NSSI behavior.

CONCLUSIONS

These findings highlighted the aggravated impact of the COVID-19 on NSSI, and suggested that individual neuroticism, impulsivity, and self-control traits might be crucial for the development of NSSI behavior among adolescent students.

A systematic review and meta-analysis of factors related to non-suicidal self-injury among Chinese adolescents

BACKGROUND

Over the past several decades the prevalence of adolescent non-suicidal self-injury (NSSI) has been rising steadily. Understanding the factors associated with NSSI is a critical public health concern. The current study aims to explore the critical factors related to NSSI among Chinese adolescents.

METHODS

A systematic literature search was conducted to identify the studies meeting our eligibility criteria (published until June 2022) in PubMed, Web of Science, Science Direct, Springer Link, CNKI, VIP, and Wanfang data. The meta-package of R language was used to perform a meta-analysis to compute the pooled effect (r).

RESULTS

A total of 59 studies were included in this analysis, with a sample size of 192,546. Twenty-four democratic, personal, and social factors were examined in current study. The pooled effect value (r) has revealed that 23 factors are associated with NSSI behaviors among Chinese adolescents. The factor, Internet addiction, has demonstrated the greatest association with NSSI compared to other factors.

CONCLUSION

Consistent with previous studies on adolescent NSSI, findings have demonstrated that a number of demographic, personal, and social factors significantly contribute to NSSI behaviors among Chinese adolescents. Future research on prevention and intervention for adolescent NSSI may benefit from targeting these factors.

Child Maltreatment, Peer Victimization, and Mental Health: Neurocognitive Perspectives on the Cycle of Victimization

Children who experience maltreatment are at increased risk of revictimization across the life span. In childhood, this risk often manifests as peer victimization. Understanding the nature of this risk, and its impact on mental health, is critical if we are to provide effective support for those children who are most vulnerable. A systematic scoping review was conducted using Google Scholar and PsycINFO. Studies on adults, psychiatric, and/or inpatient populations were excluded. Included studies concerned all forms of child maltreatment and peer victimization. We found 28 studies about the association between maltreatment experience and peer victimization as well as peer rejection. We review the evidence documenting the relation between these adverse childhood experiences and mental health. The evidence suggests that maltreatment and peer victimization have additive effects on mental health outcomes. A number of theoretical developmental frameworks that delineate putative mechanisms that might account for an association are considered. Building on prior research, we then discuss the role of recent neurocognitive findings in providing a multilevel framework for conceptualizing mental health vulnerability following maltreatment. In addition, we consider how altered neurocognitive functioning following maltreatment may shed light on why affected children are more likely to be victimized by their peers. Specifically, we consider the threat, reward, and autobiographical memory systems and their role in relation to stress generation, stress susceptibility, and social thinning. Such a mechanistic understanding is necessary if we are to reduce the likelihood of peer victimization in children exposed to maltreatment, and move to a preventative model of mental health care.

An RDoC-based approach to adolescent self-injurious thoughts and behaviors: The interactive role of social affiliation and cardiac arousal

Recent theoretical models have posited that increases in self-injurious thoughts and behaviors (SITBs) during adolescence may be linked to failures in biological stress regulation in contexts of social stress. However, there is a lack of data examining this hypothesis during the transition to adolescence, a sensitive period of development characterized by changes across socioaffective and psychophysiological domains. Building on principles from developmental psychopathology and the RDoC framework, the present study used a longitudinal design in a sample of 147 adolescents to test whether interactions among experiences of social (i.e., parent and peer) conflict and cardiac arousal (i.e., resting heart rate) predicted adolescents' engagement in SITBs (i.e., nonsuicidal self-injury, NSSI; and suicidal ideation; SI) across 1-year follow-up. Prospective analyses revealed that adolescents experiencing a combination of greater peer, but not family, conflict and higher cardiac arousal at baseline showed significant longitudinal increases in NSSI. In contrast, social conflict did not interact with cardiac arousal to predict future SI. Findings indicate that greater peer-related interpersonal stress in adolescents may increase risk for future NSSI among youth with physiological vulnerabilities (i.e., higher resting heart rate) that may be markers of maladaptive stress responses. Future research should examine these processes at finer timescales to elucidate whether these factors are proximal predictors of within-day SITBs.

Peer Victimization and Adolescent Non-Suicidal Self-Injury: The Mediating Role of Alienation and Moderating Role of Mindfulness

Peer victimization and non-suicidal self-injury (NSSI) are two major public health problems, with the former being associated with outward attack and the latter characterizing inward attack. Peer victimization has been shown to be associated with adolescents' NSSI. However, less is known about the mechanism underlying the association. Based on the experiential avoidance model of NSSI, this study tested whether the sense of alienation mediated the association between peer victimization and NSSI, and whether this process was weakened by mindfulness. A total of 1,574 Chinese adolescents (51.1% girls; ages 12-16 years) completed questionnaires concerning NSSI, peer victimization, alienation, and mindfulness. Regression-based analyses indicated that peer victimization predicted adolescents' NSSI through the indirect effect of alienation, and mindfulness weakened this indirect effect. These findings suggest that victimized adolescents may injure themselves as an emotion regulation strategy. The results highlight the importance to implement programs aimed to improve the school climate to reduce the risk of adolescent NSSI. Furthermore, we underscore the need to include emotion-regulation training (e.g., mindful practice) into bully intervention programs to prevent NSSI.

Does Involvement in Peer Bullying Invite Self-Injury?: The Association Between Peer Bullying and Self-Injury in a Clinical Sample

Previous studies have linked peer bullying to nonsuicidal self-injury (NSSI). However, the evidence is largely limited to population-based groups. This study examined whether there is a relationship between NSSI and being a victim of peer bullying among adolescents in a clinical sample and how this may be influenced by types of bullying. The sample consisted of 96 outpatients with NSSI and 107 healthy adolescents. The Inventory of Statements About Self-Injury, Peer Bullying Scale, and Rosenberg Self-Esteem Scale were applied. Whereas the scores of each bullying type of adolescents with NSSI were significantly higher, their self-esteem scores were significantly lower. Each victimization score of bullying had a negative correlation with NSSI-onset age and self-esteem scores and a positive correlation with self-injury scores. This study demonstrated that being a victim of any type of bullying is strongly associated with self-injury. It would be advisable to screen adolescents with self-injury for exposure to bullying, and vice versa.

For Better or Worse?: The role of cognitive flexibility in the association between nonsuicidal self-injury and suicide attempt

Nonsuicidal self-injury (NSSI) has been repeatedly associated with increased suicide risk. However, the transition from NSSI to suicidal thoughts and behaviors still remains as an enigma. One possible construct that may influence this relationship is cognitive flexibility, which refers to the ability to adapt responses/strategies based on environmental feedback. It may be that greater cognitive flexibility increases one's cognitive accessibility to suicide, making it a more viable option upon distress especially for those with a prior history of NSSI. Conversely, it may be that less cognitive flexibility creates a negative bias that exacerbates the effects of NSSI on suicide. Thus, in this study, we examined how NSSI characteristics (i.e., frequency and methods) interact with cognitive flexibility to predict lifetime suicide attempt (SA) history. Participants were 505 individuals with a lifetime history of NSSI who completed a survey assessing for their NSSI experiences, cognitive flexibility, and SA history. Moderation analyses were conducted while controlling for sexual orientation, which significantly predicted SA history. Results indicated a significant interaction between number of NSSI methods endorsed and cognitive flexibility. In particular, individuals were more likely to have had a history of SA if they scored higher on the alternative subscale of cognitive flexibility. The results suggest that the adaptive value of cognitive flexibility may be context dependent, and highlight the importance of personalized care among those who engage in self-harm.

Longitudinal Relationship between Bullying Victimization and Non-Suicidal Self-Injury among Chinese Adolescents: The Buffering Roles of Gratitude and Parental Autonomy Support

Drawing on the resilience-oriented socioecological framework, the current study contributes to scarce scholarship by exploring intrapersonal (i.e., gratitude) and interpersonal (i.e., parental autonomy support) factors in the longitudinal association between bullying victimization and adolescent non-suicidal self-injury (NSSI). Participants were 238 Chinese adolescents (Mage at Time 1 (T1) = 13.45 years; 106 girls and 132 boys) based on a two-wave prospective design with data spanning one year. At T1, adolescents self-rated all study variables, and at Time 2 (T2), youth again reported their NSSI. The results showed a significant main effect (b = 0.12, SE = 0.05, p = 0.04), indicating that bullying victimization was positively related to T2 NSSI one year later, even controlling for T1 NSSI. Moderation analyses further indicated that parental autonomy support buffered against the positive association between bullying victimization and T2 NSSI, but only when adolescents experienced lower levels of gratitude. Specifically, for adolescents with lower levels of gratitude, high levels of parental autonomy support, in a compensatory way, prevented adolescents from NSSI after victimization occurred (b = -0.03, SE = 0.09, p = 0.78); by contrast, for those with higher levels of gratitude, bullying victimization was not significantly related to T2 NSSI, regardless of the levels of parental autonomy support (b = 0.07, SE = 0.04, p = 0.59 for higher parental autonomy support; b = 0.01, SE = 0.07, p = 0.93 for lower parental autonomy support). These findings suggest that gratitude and parental autonomy support, manifesting in a compensatory interaction pattern, could serve as targeted agents for breaking the vicious linkage between bullying victimization and NSSI.

The impact of gender and age on bullying role, self-harm and suicide: Evidence from a cohort study of Australian children

There has been limited longitudinal investigation to date into the association between bullying, self-harm, and suicidality in Australia and the impact of specific demographic differences on this relationship. This is despite the continued rise in the incidence of bullying, self-harm, and suicide. As such, the current study draws on data from the Longitudinal Survey of Australian children (LSAC) to examine the association between bullying, self-harm, and suicidality and explore the impact of demographic differences across three bullying related behaviors (being bullied, bullying others and being both bullied and bullying others). The evidence indicates that bully-victims exhibit the highest risk of self-harm and suicidality in Australia. When considering demographic differences, it was identified that females and adolescents aged 16-17-years-of-age had the highest risk of self-harm and suicidality. Further, a direct curvilinear relationship between age and the categories of self-harm was identified with an inflection point around 16-17 years. The study supports the need for further investigation into the association between bullying, self-harm, and suicidality longitudinally with a particular focus on other moderators.

Reciprocal associations between peer problems and non-suicidal self-injury throughout adolescence

BACKGROUND

Peer problems have emerged as important predictors of Non-Suicidal Self-Injury (NSSI) development during adolescence. However, the possibility that adolescents who engage in NSSI may, in turn, be at increased risk for experiencing difficulties with their peers has rarely been examined. This study investigated the reciprocal associations between peer problems (e.g. peer victimization, friendship stress and loneliness) and NSSI throughout adolescence, distinguishing between- and within-person effects.

METHOD

Participants were 866 adolescents (54.5% females; M_age  = 13.12 years, SD = 0.78), who took part in six waves of data collection. Adolescents completed self-report measures of NSSI, friendship stress and loneliness and they took part in a peer nomination procedure to assess peer victimization. Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were used to estimate within-person cross-lagged effects between each peer problem and NSSI from Grade 7 to 12.

RESULTS

After accounting for between-person associations between peer problems and NSSI, results indicated that higher-than-usual levels of NSSI predicted higher-than-usual levels of adolescents' own friendship stress, loneliness and peer victimization at the subsequent time point. Yet, sensitivity analyses revealed that most of these effects were strongly attenuated and explained by within-person fluctuations in depressive symptoms. No within-person cross-lagged effects from peer problems to NSSI were found.

CONCLUSIONS

Findings highlight that the associations between peer problems (i.e. friendship stress, loneliness) and NSSI may be largely explained by shared underlying factors; yet, some evidence also suggests that NSSI engagement may increase adolescents' risk to experience difficulties in the relationships with their peers, in part via increases in depressive symptoms.

A meta-analysis of the relationship between bullying and non-suicidal self-injury among children and adolescents

Non-suicidal self-injury (NSSI) has attracted increasing attention due to its high detection rate, high risk and high repeatability. There is a need for the early identification of preventable occurrence factors, which is necessary to facilitate screening and intervention, especially to facilitate the early detection of high-risk individuals. This research aims to investigate the relationship between bullying behaviour and non-suicidal self-injury among children and adolescents by means of meta-analysis. The PubMed, Embase, Web of Science, SCOPUS, PsycINFO, CKNI and WAN FANG databases were searched from inception to 14 December 2021 for studies that explored the relationship between bullying behaviour and NSSI among children and adolescents. A total of 29 articles met the inclusion criteria of the meta-analysis, and 54 independent effect sizes were obtained, including 53,501 subjects. Victims [OR 2.46 (95% CI 2.14-2.83); p < 0.001], bullies [OR 2.12 (95% CI 1.37-3.27); p < 0.001], and bully-victims [OR: 2.98 (95% CI 1.85-4.82); p < 0.001] were more likely to have NSSI than uninvolved children or adolescents. In addition, analyses showed the absence of publication bias. In the victim group, the older the age was, the lower the risk of NSSI (z = - 3.74, p = 0.00). Gender does not play a moderating effect on the association between bullying behaviour and non-suicidal self-injury. The relationship between involvement in bullying and NSSI was demonstrated. By taking measures to prevent bullying, the incidence of NSSI in children and adolescents can be potentially reduced.

Gratitude buffers the effects of stressful life events and deviant peer affiliation on adolescents’ non-suicidal self-injury

Although stressful life events have been shown to be a key risk factor for adolescent NSSI, the potential mediators and moderators of this relationship are unclear. Based on the social development theory and the organism-environment interaction model, we tested whether the link between stressful life events and adolescent NSSI was explained in part by deviant peer affiliation, and whether this process was buffered by gratitude. Chinese adolescents (N = 854; M_age = 16.35; 68.50% female) anonymously completed questionnaires to assess the study variables. The present study demonstrated that stressful life events was linked to NSSI in part because of deviant peer affiliation, and high gratitude was a key protective factor to buffer this indirect effect. Teaching gratitude may be a helpful component of prevention and intervention programs to reduce adolescent NSSI.

The relationship between negative peer relationship and non-suicidal self-injury in Chinese adolescents: A moderated-mediation model

Objective

The objective of the study was to investigate the mediating effect of regulatory emotional self-efficacy (RESE) between negative peer relationship and non-suicidal self-injury (NSSI), as well as the moderating effect of gender difference.

Methods

A study of 578 Chinese adolescents (46.9% males, mean age = 16.32 years, SD =0.54) was conducted using the Child and Adolescent Peer Relationship Inventory, Regulatory Emotional Self-Efficacy Scale, and the Adolescent Self-Injury Questionnaire.

Results

Negative peer relationship was positively correlated with NSSI, and RESE was negatively correlated with negative peer relationship and NSSI. RESE mediated the association between negative peer relationship and NSSI. The first stage(predicting the effect of negative peer relationship on RESE) and the second stage (predicting the effect of RESE on NSSI) of the mediation effect of RESE were both moderated by gender. Specifically, compared with boys, the effect of negative peer relationship on RESE was stronger for girls, and the effect of RESE on NSSI was stronger for girls than boys.

Conclusion

Negative peer relationships may influence NSSI of adolescents through the mediating effect of RESE and the moderating role of gender.

Correlates of Non-suicidal Self-Injury in Adolescent Psychiatric Patients in China

BACKGROUND

Non-suicidal self-injury (NSSI) has attracted more and more attention from schools, mental health workers and even the whole society in China. The aim of this study was to explore influencing factors and clinical characteristics of NSSI in adolescent psychiatric patients in China, and provide valuable information for the intervention and treatment of NSSI.

METHODS

The sample included 157 adolescents, 114 were female (72.6%), aged 12-18 years (M = 15.39, SD = 1.81). Assessments were performed using Childhood Trauma Questionnaire-Short Form, the Revised Olweus Bully/Victim Questionnaire, the modified version of Adolescents Self-Harm Scale, Montgomery-Asberg Depression Rating Scale, Brief Psychiatric Rating Scale, the Young Mania Rating Scale and the Mini International Neuropsychiatric Interview. Clinical characteristics were collected from electronic medical record system.

RESULTS

Adolescent patients with NSSI experienced more adverse life events including peer bullying, childhood trauma and romantic relationship trouble. They had more times of hospitalization, higher dosage of psychotic medication, and more severe depressive symptoms.

CONCLUSIONS

It is very necessary to evaluate negative life events, including childhood trauma, peer bullying etc., in adolescent patients with NSSI. It has important clinical implications for evaluating the risk factors of NSSI and giving effective intervention treatment. Timely and effective treatment of these patients' depressive symptoms will also contribute to the relief of NSSI.

Peer Victimization and Nonsuicidal Self-Injury Among Chinese Left-Behind Children: The Moderating Roles of Subjective Socioeconomic Status and Social Support

Peer victimization is a serious issue among school-aged children. Chinese left-behind children tend to experience peer victimization and associated nonsuicidal self-injury (NSSI) behavior. However, the possible improvement of subjective socioeconomic status (SES) based on increased family income may serve to buffer the relationship between peer victimization and NSSI, and this buffering effect may differ by level of social support. Thus, the current study aimed to examine the moderating effect of subjective SES on the relationship between peer victimization and NSSI by the level of social support among Chinese left-behind children. A total of 431 left-behind children and 447 non-left-behind children (comparison group) completed self-report scales measuring peer victimization, NSSI, subjective SES, and social support. Results showed that peer victimization was positively related to NSSI among left-behind children, but not among non-left-behind children. Moreover, for left-behind children with low levels of social support, high subjective SES intensified the association between peer victimization and NSSI; peer victimization was positively associated with NSSI among left-behind children who reported high subjective SES, but not among those with low subjective SES. However, high levels of social support seemed to protect the left-behind children with high subjective SES who experienced peer victimization from NSSI. For non-left-behind children with both parents present, high subjective SES played a protective role in the association between peer victimization and NSSI, regardless of the levels of social support they enjoyed. These findings contribute to an understanding of subjective SES as a moderating mechanism in the association between peer victimization and NSSI among left-behind children. Social support proved central to the protective role of subjective SES. Intervention programs to enhance social support can help to strengthen the protective effect of subjective SES on NSSI among left-behind children who experience peer victimization.

Non-suicidal self-injury is associated with psychotic like experiences, depression, and bullying in Korean adolescents

AIM

Non-suicidal self-injury (NSSI) is common among adolescents, and several different factors can affect its prevalence. The present study examined the associated characteristics predicting NSSI among adolescents in South Korea.

METHODS

In total, 1674 high school students were recruited for a cross-sectional survey. They completed self-reported assessments, including the Deliberate Self-Harm Inventory (DSHI), the Center for Epidemiological Studies Depression Scale (CESD), the State-Trait Anxiety Inventory for Children (STAIC), and the Prodromal Questionnaire-16 (PQ-16), as well as their bullying experience. The NSSI group was defined as the sample group with at least one NSSI behaviour on the DSHI scale. A logistic regression analysis was performed using the NSSI group as the dependent variable.

RESULTS

The prevalence of NSSI was 28.3% (boys, 30.4%; girls, 24.4%) among adolescents. The most common type of NSSI behaviour among adolescents was interference with wound healing and sex differences in the method were examined. The CES-D, STAIC-trait, and PQ-16 scores were significantly higher and the RSES score was significantly lower in the NSSI group than those in the non-NSSI group. Participants' experience with bullying, such as being victims, bullies, bully-victims, and witness to bullying, were more likely to be in the NSSI group. In a logistic regression analysis, NSSI was significantly associated with male sex, low academic achievement, higher depression, psychotic-like experiences, being bullied, and witnessing bullying.

CONCLUSION

The results of this study suggest the need to identify and manage related psychologic factors in adolescents with NSSI, including psychotic-like symptoms.

Do Gender and Age Moderate the Relationship between Friendship Quality and Non-Suicidal Self-Injury in Community Children and Adolescents?

In the present study, we investigated the relationship between friendship quality (dimensions) and non-suicidal self-injury (NSSI) as well as the moderating role of gender and age in this relationship. The sample consisted of 463 children and adolescents (50.10% female, age range: 9–17 years). Friendship quality and NSSI were measured using the Friendship Qualities Scale (FQS; Bukowski, Hoza, & Boivin, 1994) and the Self Harm Inventory (SHI; Sansone, Wiederman, & Sansone, 1998), respectively. Overall, total friendship quality and NSSI were significantly and negatively related. Additionally, the relationship between total friendship quality and NSSI was moderated by gender and age. Specifically, girls with low friendship quality reported more NSSI; whereas for boys an opposite effect was found. As for age, friendship quality and NSSI were positively related in older participants. In younger participants, a relationship between friendship quality and NSSI seemed rather absent. This study highlights the important association between friendship quality and NSSI, as well as gender- and age-related differences in this association, which should be taken into account in the prevention and treatment of NSSI.

The relationship between peer victimization and social anxiety among adolescents: a moderated mediation model with cognitive flexibility and affect intensity

Building a friendship with peers is an important developmental task. However, peer victimization and social anxiety are among the most disturbing problems and have impaired adolescents' adaptive development. A total of 942 adolescents completed the survey. The results showed that peer victimization was related to social anxiety and that this effect was mediated by cognitive flexibility and moderated by affect intensity. Specifically, the damage of peer victimization and social anxiety was aggrevated for those with high levels of affect intensity. The current study provides evidence for the association between peer victimization and social anxiety. It contributes to the literature by clarifying the equivocal findings and uncovering the underlying mechanisms of the relationship between peer victimization and social anxiety. In the future, researchers and teachers should pay attention to adolescents' peer social status as early as possible, especially for adolescents with higher levels of affect intensity.

Cyberbullying victimization and nonsuicidal self-injury in adolescents: The role of maladaptive schemas and dispositional mindfulness

BACKGROUND

Previous research has found associations between cyberbullying victimization and nonsuicidal self-injury (NSSI) in adolescents. Exploration of the possible mediating variables involved is necessary to support intervention with victims.

OBJECTIVE

This study examined whether depression and early maladaptive schemas (EMS) mediate the association between cyberbullying victimization and NSSI, along with the potential protective role of dispositional mindfulness.

PARTICIPANTS AND SETTING

A total of 742 Spanish adolescents (50.20% girls) between 12 and 17 years old (M = 14.58; SD = 1.00) participated in the final sample.

METHOD

Participants completed measures of cyberbullying victimization, NSSI, EMS, depression, and mindfulness facets. Mediational models moderated by facets of mindfulness were tested.

RESULTS

Cyberbullying victimization was associated with NSSI through increased depression and EMS. Acting with awareness buffered the association between cyberbullying victimization and NSSI, whereas non-judging increased the association between cyberbullying victimization and depression.

CONCLUSIONS

Cybervictimization is associated with NSSI. The mindfulness facet of acting with awareness plays a protector role. Interventions in NSSI and cyberbullying could benefit from these findings.

Relationships between Non-Suicidal Self-Injury and Other Maladaptive Behaviors: Beyond Difficulties in Emotion Regulation

Non-suicidal self-injury (NSSI) co-occurs with both other maladaptive behaviors (e.g., aggression) and emotion dysregulation. However, the extent to which these maladaptive behaviors are linked to NSSI independent of emotion dysregulation is unclear. The present study examined relationships between NSSI and six other maladaptive behaviors among university undergraduates. When controlling for demographic variables, emotion dysregulation, and other maladaptive behaviors, binge eating, purging, illicit drug use, and physical aggression were each related to lifetime NSSI history and/or severity. No maladaptive behaviors were significantly related to the presence of current diagnostic-level NSSI in these multivariate analyses. Results suggest that some maladaptive behaviors may relate uniquely to NSSI risk independent of emotion dysregulation, highlighting the importance of considering such behaviors in self-injury assessment and treatment.

Predictors and consequences of non-suicidal self-injury in relation to life, peer, and school factors

INTRODUCTION

Numerous life, peer, and school-related factors have been found to be associated with non-suicidal self-injury (NSSI) among adolescents; however, most studies have not explored the possible reciprocal nature of these associations. The aim of the current study was to examine bidirectional and longitudinal associations between NSSI and several life, peer, and school-related factors (i.e., stressful life events, peer relationships, academic achievement, and attitudes towards school).

METHOD

Community-based adolescents completed questionnaires assessing the variables of interest at three time points; age 12 (T1; 55.09% girls), age 13 (T2; 56.95% girls), and ages 14-15 (T3; 57.41% girls). In total, 529 adolescents provided complete data across all three-time points.

RESULTS

Analyses showed a bidirectional association between NSSI and both attitudes towards school and stressful life events. Specifically, stressful life events at T2 predicted engagement in NSSI at T3, and NSSI at T2 predicted increased risk of stressful life events at T3. Similarly, having negative attitudes towards school predicted NSSI at T2, which, in turn, predicted negative attitudes towards school at T3. Further, academic achievement at T1 was negatively associated with NSSI at T2. Peer relationships were neither a predictor nor a consequence of NSSI.

CONCLUSIONS

Our results suggest that NSSI can be both a predictor and a consequence of various life, and school factors. Focus on these factors in prevention and intervention efforts for NSSI among adolescents may be warranted.

Rejection sensitivity and adolescent non-suicidal self-injury: Mediation through depressive symptoms and moderation by fear of self-compassion

OBJECTIVES

Rejection sensitivity is a risk trait that contributes to the relationships between rejection experiences in various domains and non-suicidal self-injury (NSSI). However, research about the association between rejection sensitivity and NSSI has still been understudied. This study sought to examine the mediating role of depressive symptoms and the moderating role of fear of self-compassion in the association between rejection sensitivity and adolescent NSSI.

DESIGN

A cross-sectional correlational design was employed through which rejection sensitivity, depressive symptoms, fear of self-compassion, and NSSI experiences in the past year were measured.

METHODS

Seven-hundred twenty-eight Chinese secondary school students (51.1% females; mean age = 14.07, SD = 0.75) were included by convenient sampling.

RESULTS

Regression analyses revealed that depressive symptoms worked as a mediator in the association between rejection sensitivity and NSSI. It was also found that fear of self-compassion acted as a moderator, such that a higher level of fear of self-compassion strengthened the link between rejection sensitivity and depressive symptoms and the direct link between rejection sensitivity and NSSI.

CONCLUSIONS

These findings highlight the need to address adolescents' rejection sensitivity, depressive symptoms, and fear of self-compassion in preventing and intervening NSSI.

PRACTITIONER POINTS

Focusing on rejection sensitivity might help understand the relationships between intra- and interpersonal distress and NSSI. The findings of this study evidenced the risk effect of adolescents' rejection sensitivity on NSSI and the partial mediation of depressive symptoms in the link. Targeting adolescents' rejection sensitivity will be beneficial in developing NSSI-related prevention and intervention programs. This study also found that adolescents' fear of self-compassion magnified the associations between rejection sensitivity, depressive symptoms, and NSSI. It suggests that targeting adolescent's fear of self-compassion will also be beneficial.

Bullying Victimization: Investigating the Unique Contribution of Homophobic Bias on Adolescent Non-suicidal Self-injury and the Buffering Role of School Support

Research on bullying victimization has expanded to specific forms of harassment based on discriminatory bias, which involve aggressive behavior targeting an individual's identity characteristics, such as sexual orientation and/or gender expression. Recent studies have documented elevated health risks associated with victimization based on homophobic bias, above and beyond general victimization. The aim of the current study was to test the unique contribution of homophobic victimization on adolescent non-suicidal self-injury (NSSI) and to analyze the buffering role of teachers and classmates support. Participants were 770 adolescents (55.5% females; Mage = 15.35, SD = 1.62) enrolled in Italian public schools in grade nine (N = 483) and 12 (N = 287). All measures were collected during Spring 2016 using self-reported questionnaires. Zero-inflated Poisson regression analyses suggested that homophobic victimization had a unique contribution on NSSI frequency of engagement once initiated, but not on the probability of engaging in NSSI at least once. High classmates support was negatively associated with adolescents’ engagement in NSSI. Furthermore, higher levels of classmates support were associated with a lower NSSI frequency only for youth who reported low levels of homophobic victimization. In contrast, the association between classmates support and NSSI frequency was nonsignificant when youth reported high levels of homophobic victimization. No significant effects were found for teachers support. Overall, our findings underscore the need to address the serious concern of homophobic victimization within schools and the importance of promoting healthy and positive identity development in adolescence.

The Relationship Between Cybervictimization and Non-suicidal Self-Injury in Chinese Adolescents: A Moderated-Mediation Model

The present study investigated the mediating role of negative emotion in the relationship between cybervictimization and non-suicidal self-injury (NSSI), and the moderating role of friendship quality in the indirect relationship. This model was tested with 1,326 Chinese adolescents who suffered from cyberbullying in the last 1 year; 727 were boys and 591 were girls, and their mean age was 13.67 years (SD = 1.34, range 11-17). Participants filled out questionnaires regarding cybervictimization, negative emotion, friendship quality, and non-suicidal self-injury. After demographic variables were controlled, cybervictimization was significantly positively associated with non-suicidal self-injury. Mediation analysis revealed that negative emotion partially mediated the association between cybervictimization and non-suicidal self-injury. Moderated mediation analysis further indicated that the mediated path was weaker for adolescents with higher levels of friendship quality. These findings underscore the importance of identifying the mechanisms that moderate the mediated path between cybervictimization and non-suicidal self-injury among adolescents.

An internet-based emotion regulation intervention versus no intervention for nonsuicidal self-injury in adolescents: study protocol for a feasibility trial

BACKGROUND

Non-suicidal self-injury (NSSI) has gained increased attention in recent years due to increased prevalence, especially among adolescents. Evidence-based interventions for NSSI are sparse. Emotion regulation individual therapy for adolescents (ERITA) is an online intervention that needs investigation. Non-randomised studies suggest ERITA improves emotion regulations skills and reduces NSSI frequency. Before conducting a large pragmatic randomised clinical trial, we aim to investigate the feasibility of ERITA in Denmark.

METHODS

A randomised, parallel group feasibility trial comparing ERITA as add on to treatment as usual versus treatment as usual in 30 adolescents age 13-17 years with recurrent NSSI referred to outpatient clinics in The Child and Adolescent Mental Health Services in the Capital Region of Denmark. Feasibility outcomes are (1) completion of follow-up, (2) the fraction of eligible participants who consent to inclusion and randomisation and (3) compliance with the intervention. Clinical outcomes such as self-injury frequency and the ability to regulate emotions will be investigated exploratorily.

DISCUSSION

Internet-based interventions are assumed to be appealing to adolescents by being easily accessible and easy to navigate by tech natives. Disclosure of self-injury behaviour may be facilitated by an online intervention. The evidence for self-injury specific treatment needs to be extended but prior to a large clinical trial, the feasibility of methods and procedures must be assessed.

Impact of the COVID-19 pandemic on students at elevated risk of self-injury: The importance of virtual and online resources

Non-suicidal self-injury (NSSI), which involves deliberate damage to body tissue without suicidal intent, has long been a concern for schools and school staff. Secondary schools are an ideal setting in which to identify, and appropriately refer, students who self-injure as well as implement evidence-based prevention and early intervention programs. However, in the context of the global COVID-19 pandemic, schools have been closed and students sent home to learn online. This may result in the exacerbation of existing anxieties and pose several new stressors that cumulatively may increase risk of NSSI. In this article, we draw on recent research and our collective experience working with schools, as well as digital mental health, to outline some of these potential stressors and offer resources for school staff to help students who are engaging in or at risk of NSSI.

Cyberbullying Victimization and Non-suicidal Self-Injurious Behavior Among Chinese Adolescents: School Engagement as a Mediator and Sensation Seeking as a Moderator

Although a large body of research has indicated that cyberbullying victimization is a crucial risk factor for adolescent non-suicidal self-injury (NSSI) behavior, the mediating and moderating mechanisms underlying this relationship remain unclear. To address this research gap, this study, based on the social control theory and the organism-environment interaction model, was designed to test whether school engagement mediated the relationship between cyberbullying victimization and adolescent NSSI and whether this mediating effect was moderated by sensation seeking. A sample of 1,102 adolescents (M_age = 13.17; SD = 0.69) anonymously completed the questionnaires. The results showed that the positive association between cyberbullying victimization and adolescent NSSI was mediated by school engagement. Moreover, this indirect link was significant for adolescents with high-level sensation seeking but non-significant for adolescents with low-level sensation seeking. These findings highlight school engagement as a potential mechanism linking cyberbullying victimization to adolescent NSSI, and high sensation seeking was an important risk factor to amplify this indirect effect. Intervention programs aimed at reducing NSSI among adolescents may benefit from the current research.

Social rejection, popularity, peer victimization, and self-injurious thoughts and behaviors among adolescents: A systematic review and meta-analysis

Self-injurious thoughts and behaviors (SITBs) are significant public health problems in adolescence. The current article provides a comprehensive systematic review examining the relationship between events leading to perceived low relational evaluation (e.g. social rejection) and SITBs among adolescents. Theoretical work posits that low relational evaluation is experienced as psychologically painful, a known correlate of SITBs. Therefore, events leading to low relational evaluation may be particularly informative in understanding the context of SITBs. The current review examines how experiences of low relational evaluation that are hypothesized to elicit psychological pain, such as social rejection, low popularity, and peer victimization are related to engagement in SITBs in adolescence. A total of 56 articles meeting inclusion criteria were identified. The hypothesis of an association between indicators of low relational evaluation and SITBs was generally supported throughout the literature, with more consistency found among studies examining suicidal ideation specifically. However, interpretation of the findings is constrained by various methodological limitations of studies. The present review concludes with a theoretical conceptualization of the relationship between perceived relational value and SITBs, leveraging social and evolutionary psychological theory, to guide future research into this topic.

Are Korean children free from suicide? Risk and protective factors within a transactional-ecological perspective

This study aimed to explore and identify the trends and risks, as well as the protective factors of child suicide in Korea. Data from the 10th year Korea Welfare Panel Study in 2016 were used. These data were collected from 458 fourth to sixth grade boys and girls in elementary schools. The results showed that the mean suicidal ideation score was 1.55, the suicide attempt rate was .9%, and the mean number of suicide attempts was .2. Suicidal ideation was more prevalent in children who reported the absence of a parental figure, frequent experiences of school violence, increased Internet use, and decreased guidance and supervision from parents. The presence of parental figure explained the greatest amount of variance. Logistic regression analysis with suicide attempts as the dependent variable demonstrated that family income was a significant variable. Regarding the mediating roles of depression and anxiety, Internet usage directly affected children's suicidal ideation, while the experience of school violence, academic stress, and parents' guidance and supervision affected suicidal ideation, which was mediated by the child's depression and anxiety. Depression and anxiety had a positive impact on suicidal ideation. Based on these results, implications and interventions were suggested.

Research on the Relationships between Psychological Problems and School Bullying and Non-Suicidal Self-Injury among Rural Primary and Middle School Students in Developing Areas of China

(1) Purpose: To analyze the role of psychological problems in connection with school bullying and non-suicidal self-injury (NSSI) among rural primary and middle school students in developing areas of China. (2) Methods: A multi-stage, stratified, cluster random sampling method was used to select 2284 rural primary and middle school students in Jiangxi Province for study. Questionnaires regarding the health risk behaviors of children in developing areas were left behind at primary and middle schools, and they were later collected and analyzed by using the mental health diagnostic monitoring scale for Chinese primary and middle school students. Pearson correlation, logistic regression, and bootstrap tests were conducted to analyze the association between psychological problems, school bullying, and NSSI. (3) Results: The incidence of NSSI in rural primary and middle school students in Jiangxi Province was 14.84%. Compared with other children with behavioral problems, those who had experienced school bullying and had mild/severe psychological problems were more likely to have engaged in NSSI behaviors (p < 0.001). Psychological problems have a mediating effect between school bullying and NSSI, which accounted for 12.96% of the total effect. (4) Conclusion: Psychological problems are likely an effect modifier in the connection between school bullying and NSSI behaviors. Therefore, effectively targeting psychological problems in rural primary and middle school students in Jiangxi Province may help prevent and control NSSI behaviors in students who have experienced school bullying.

Life Events Predicting the First Onset of Adolescent Direct Self-Injurious Behavior-A Prospective Multicenter Study

PURPOSE

Self-injurious behavior is a frequent phenomenon in adolescence. The present study prospectively examined life events as risk factors for the first onset of direct self-injurious behavior (D-SIB) in the Saving and Empowering Young Lives in Europe school-based multicenter sample.

METHODS

Longitudinal assessments with an interval of 1 year were performed within a sample of 1,933 adolescents (51.47% females; mean age 14.84 ± .9 years) from 10 European countries and Israel.

RESULTS

The number of life events during the past 6 months predicted the first onset of D-SIB in the following year. Gender neither predicted the onset of D-SIB nor moderated the association with life events. Moreover, analyses of individual events identified a range of mainly interpersonal events within both family and peer group as proximal risk factors for first episode D-SIB.

CONCLUSIONS

The results support the critical role of interpersonal life events in the development of D-SIB for both genders and refine the conceptualization of proximal risk factors in terms of accumulated stressors and interpersonal events.

Patterns of Bullying Victimization and Associations with Mental Health Problems in Chinese Adolescents: A Latent Class Analysis

Bullying victimization in school students is a serious public health concern and has been linked to a wide range of mental health problems. The current study aims to examine patterns of involvement in different types of bullying victimization among Chinese adolescents and evaluate the associations between bullying victimization and mental health problems. Cross-sectional data from 20,722 middle school students from Guangdong Province were sampled using a multistage, stratified cluster-randomized sampling method. Latent class analysis (LCA) was performed on seven items representing bullying victimization. Levels of mental health outcomes were compared across each latent class. Four latent classes were identified for boys: the high victimization class (0.6%), the moderate victimization class (2.8%), the verbal victimization class (12.4%), and the low victimization class (84.2%). For girls, three latent classes were identified: the high victimization class (0.7%), the moderate victimization class (5.6%), and the low victimization class (93.7%). Characteristics of the item probabilities were different between boys and girls. For both genders, a graded relationship was found between bullying victimization class membership and mental health outcomes. These findings underline the complexity of bullying victimization patterns among Chinese adolescents. Students with higher involvement in bullying victimization have more severe mental health problems.

Predicting the incidence of non-suicidal self-injury in college students

Background:

Despite increased awareness that non-suicidal self-injury (NSSI) poses a significant public health concern on college campuses worldwide, few studies have prospectively investigated the incidence of NSSI in college and considered targeting college entrants at high risk for onset of NSSI.

Methods:

Using data from the Leuven College Surveys (n = 4,565; 56.8%female, Mage = 18.3, SD = 1.1), students provided data on NSSI, sociodemographics, traumatic experiences, stressful events, perceived social support, and mental disorders. A total of 2,163 baseline responders provided data at a two-year annual follow-up assessment (63.2% conditional response rate).

Results:

One-year incidence of first onset NSSI was 10.3% in year 1 and 6.0% in year 2, with a total of 8.6% reporting sporadic NSSI (1–4 times per year) and 7.0% reporting repetitive NSSI (≥ 5 times per year) during the first two years of college. Many hypothesized proximal and distal risk factors were associated with the subsequent onset of NSSI (ORs = 1.5–18.2). Dating violence prior to age 17 and severe role impairment in daily life were the strongest predictors. Multivariate prediction suggests that an intervention focused on the 10% at highest risk would reach 23.9% of students who report sporadic, and 36.1% of students who report repetitive NSSI during college (cross-validated AUCs =.70–.75).

Discussion:

The college period carries high risk for the onset of NSSI. Individualized web-based screening may be a promising approach for detecting young adults at high risk for self-injury and offering timely intervention.

Bullying Victimization and Trauma

Bullying victimization and trauma research traditions operate quite separately. Hence, it is unclear from the literature whether bullying victimization should be considered as a form of interpersonal trauma. We review studies that connect bullying victimization with symptoms of PTSD, and in doing so, demonstrate that a conceptual understanding of the consequences of childhood bullying needs to be framed within a developmental perspective. We discuss two potential diagnoses that ought to be considered in the context of bullying victimization: (1) developmental trauma disorder, which was suggested but not accepted as a new diagnosis in the DSM-5 and (2) complex post-traumatic stress disorder, which has been included in the ICD-11. Our conclusion is that these frameworks capture the complexity of the symptoms associated with bullying victimization better than PTSD. We encourage practitioners to understand how exposure to bullying interacts with development at different ages when addressing the consequences for targets and when designing interventions that account for the duration, intensity, and sequelae of this type of interpersonal trauma.

Influence of Personality Traits and Its Interaction with the Phenomenon of Bullying: Multi-Centre Descriptive Study

Bullying affects thousands of teenagers worldwide and has devastating consequences. Various studies suggest that the personality of teenagers is a risk profile for bullying. The aim of this study was to analyse the relationship between the personality of teenagers aged 14 to 16 years from three education centres located in the province of Seville (Spain) and bullying in any of its victim or aggressor roles. A multi-centre cross-sectional observational descriptive study was conducted in three education centres in the province of Seville (Spain). The sample consisted of 93 students. In order to measure the two main variables, the Bull-S test was used for bullying, and the EPQ-J questionnaire was used for personality traits. A descriptive and correlation analysis was performed between variables. The results showed that 14% (n = 13) of the sample were detected as victims and another 14% (n = 13) were detected as aggressors. Statistically significant differences were found between neuroticism (p = 0.044; Phi = 0.615), sincerity (p = 0.016; V de Cramer = 0.474), and anti-social behaviour (p = 0.007; Phi = 0.620) with the variables victim/aggressor. Bullies are typically males who score high on neuroticism and anti-social behaviour, with a tendency towards social dissimulation.

Peer Victimization, Maternal Control, And Adjustment Problems Among Left-Behind Adolescents From Father-Migrant/Mother Caregiver Families

Background

Left-behind adolescents who are from father-migrant/mother caregiver families have become the main type of left-behind children in China. The migratory of fathers not only makes left-behind adolescents suffer more difficulties but also causes left-behind women to face the challenge of raising the child alone. This study examined the association among peer victimization, maternal psychological control, and adjustment problems among Chinese rural left-behind adolescents. Furthermore, we first explored the moderating role of maternal behavioral control in this relationship.

Methods

Using cross-sectional design, we recruited 194 left-behind adolescents (49% girls; mean age = 13.51, SD = 1.03) from four junior schools in the Guizhou province of China. Left-behind adolescents completed a battery of self-report questionnaires regarding peer victimization, maternal control, self-injury behaviors, depression, and loneliness.

Results

The hierarchical multiple regressions indicated that both peer victimization and maternal psychological control were positively associated with self-injury behaviors, depression, and loneliness. Moreover, maternal behavioral control played a dual role in the impact of peer victimization on self-injury behaviors depending on the levels of maternal psychological control. When left-behind women exerted high psychological control on their children, maternal behavioral control buffered the negative effect of peer victimization on self-injury behaviors. However, when left-behind women exerted low psychological control on their children, maternal behavioral control exacerbated the negative effect of peer victimization on self-injury behaviors.

Conclusion

These findings suggest that the effectiveness of behavioral control may depend on different situations, left-behind women should be cautious in exerting behavioral control over their children.

Trajectories of non-suicidal self-injury in adolescent girls following inpatient hospitalization

This study explored the growth of non-suicidal self-injury (NSSI) frequency over 2.5 years in a clinical sample of adolescent girls. Following a functional model of NSSI, the contribution of emotion dysregulation, peer victimization, and psychological maladjustment were evaluated as the predictors of NSSI trajectories. Participants of 99 girls (M_age = 16.03 years) were admitted for psychiatric hospitalization, who responded to questionnaires assessing NSSI, emotion dysregulation, relational and overt peer victimization, and internalizing and externalizing symptoms. NSSI was also assessed at 6 months and 2.5 years following the baseline assessment. Linear mixed modeling estimated NSSI frequency over time. The findings highlight the stable nature of NSSI and the contribution of emotion dysregulation and internalizing symptoms to NSSI patterns. Peer victimization and externalizing behavior problems were not the significant predictors. Developing interventions targeting these NSSI predictors early in girls' development may prevent the emergence and maintenance of NSSI.

Peer victimization, depressive symptoms and non-suicidal self-injury behavior in Chinese migrant children: the roles of gender and stressful life events

Background

Non-suicidal self-injury (NSSI) has become a worldwide health concern, especially for the disadvantaged group such as Chinese rural-to-urban migrant children. Peer victimization is a risk factor for NSSI and is quite common among Chinese migrant children. However, few studies that focused on this group have paid attention to the relationship between peer victimization and NSSI. The current study addressed this gap in the literature by examining the mediating role of depressive symptoms and the moderating role of stressful life events in the relationship between peer victimization and NSSI in male and female migrant children.

Methods

A total of 650 migrant children completed self-report surveys that addressed peer victimization, NSSI, depressive symptoms, and stressful life events.

Results

Results showed that peer victimization was significantly related to NSSI for both migrant girls and boys. Depressive symptoms mediated the relationship between peer victimization and NSSI among girls, but not among boys. Additionally, stressful life events significantly moderated the relationships between depressive symptoms and NSSI and between peer victimization and NSSI among girls; higher levels of depressive symptoms or peer victimization coupled with more stressful life events related to a higher probability of NSSI. For boys, stressful life events moderated the relationship between peer victimization and NSSI; higher levels of peer victimization combined with increased NSSI behaviors among the boys who reported more stressful life events.

Conclusions

These findings contribute to the understanding of the mechanisms that inform the relationship between peer victimization and NSSI. Moreover, they indicate that future interventions can be enhanced by targeting depressive symptoms among girls and stressful life events among both girls and boys.

I Want You to Want Me: Interpersonal Stress and Affective Experiences as Within-Person Predictors of Nonsuicidal Self-Injury and Suicide Urges in Daily Life

OBJECTIVE

To investigate near-term risk for self-injurious urges, we evaluated how within-person changes in internalizing and externalizing negative affect, as well as interpersonal rejection and criticism, impact subsequent nonsuicidal self-injury (NSSI) and suicide urges in daily life.

METHOD

Young adult women (N = 62) from an ongoing community cohort study with past-year self-injurious thoughts completed a 21-day ecological momentary assessment protocol. We used multilevel path analyses to model within-person effects of negative affect and interpersonal stress on subsequent suicide and NSSI urges within several hours.

RESULTS

When modeled simultaneously, within-person changes in internalizing, but not externalizing, negative affect predicted later self-injurious urges. Rejection and criticism predicted later self-injurious urges, with rejection showing a unique relationship to NSSI urges specifically. Effects of rejection and criticism on later NSSI and suicide urges were mediated by internalizing negative affect; rejection also retained a significant direct effect on NSSI urges.

CONCLUSION

Interpersonal stressors may be potent near-term risk factors for self-injurious urges by increasing internalizing negative affect among vulnerable individuals. The direct role of rejection and criticism on self-injurious urges is less clear, particularly for suicide. These findings have implications for understanding processes underlying self-injurious urges, as well as designing real-time interventions for these experiences in daily life.

Are Bullying Perpetration and Victimization Associated with Adolescent Deliberate Self-Harm? A Meta-Analysis

This study sought to appraise internationally published literature investigating bullying in its association with deliberate self-harm (DSH). A systematic review and series of meta-analyses using random effects models were conducted. A total of 68 effect sizes, analyzing data from 156,284 adolescents aged 11-19 years were examined. Results showed significant associations between both traditional bullying perpetration (OR 1.81, 95% CI [1.33, 2.47], p < .0001) and victimization (OR 2.34, 95% CI [1.89, 2.89], p < .0001) and DSH. Cyber-bullying victimization (OR 3.55, 95% CI [2.71, 4.65], p < .0001) and the co-occurrence of traditional and cyber-bullying victimization (OR 3.39, 95% CI [1.56, 7.37], p = .002) were also associated with DSH. Moderator analyses showed variation in results based on methodological- and sample-level variables. Findings suggested that exposure to bullying, either as perpetrators or victims, poses risks for DSH.

Adolescent non-suicidal self-injury and its relationships with school bullying and peer rejection

The central goal of this study was to examine the associations of school bullying and peer rejection with non-suicidal self-injury (NSSI), as well as their interactive role in a sample of non-clinical adolescents. Six hundred and forty adolescents (253 Males, M_age = 15.60, SD = 1.65) self-reported measures of school bullying and NSSI and provided sociometric ratings of peer rejection. The results showed that being involved in bullying (as bullies, victims, or bully-victims) increases the likelihood to engage in NSSI; being rejected by peers amplifies the probability, for victims and bully-victims, of using NSSI at least once. The findings support the hypothesis that peer relationships play a key-role in determining NSSI and the importance to implement programs aimed to improve the school climate in order to avoid maladjusted behaviors in adolescence.
