Differences in Influencing Factors Between Non-suicidal Self-Injury and Suicide Attempts in Chinese Adolescents: The Role of Gender

Adverse childhood experiences and suicidality in low-income and middle-income countries: a systematic review and meta-analysis

INTRODUCTION

Suicide is an important public health problem with a complex aetiology; this includes adverse childhood experiences (ACEs). Common to suicide and ACEs research is a lack of evidence from low-income and middle-income countries (LMICs). This review aims to evaluate associations between ACEs and suicidality in LMICs.

METHODS

In this systematic review and meta-analysis, a search for articles investigating associations between any ACEs and suicidal outcomes in LMICs was conducted using Medline, Embase, PsycINFO, CINAHL and Web of Science on 2 December 2022; updated on 14 January 2025. Cross-sectional or cohort study research articles investigating ACEs prior to age 18 and using population-based, probabilistic or total population, sampling were eligible for inclusion. Suicidal outcomes across the spectrum were eligible for inclusion. Identified records underwent two-step screening by two independent reviewers; data extraction and risk of bias assessment using Joanna Briggs Institute Critical Appraisal tools were also completed in duplicate. Random-effects models were used to calculate pooled ORs. Articles that could not be meta-analysed were narratively synthesised. Reporting of this review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement.

RESULTS

Ultimately, 118 articles were included; all were of low or moderate risk of bias and none reported on suicide mortality. Six ACEs were significantly associated with increased odds of suicidal outcomes: (1) bullying-victimisation, (2) emotional, verbal or psychological abuse victim, (3) parental separation, divorce or death, (4) physical abuse or violence victim, (5) physical attack victim and (6) sexual abuse victim. Significant ORs ranged from 1.19 to 2.61. Positive associations were found across subgroup and sensitivity analyses. Narrative review found statistically significant positive and non-significant associations between ACEs and suicidal outcomes.

CONCLUSIONS

ACEs are associated with suicidal outcomes in LMICs, highlighting the need for early intervention strategies and multisector public health approaches to reducing ACEs and their potential impacts.

Developmental trajectories of interpersonal stress in school and psychological pain contributing to self-harm in adolescents

BACKGROUND

This study investigated the trajectories of interpersonal stress and psychological pain and their effects on self-harm behaviors in adolescents and explored the reciprocal associations between interpersonal stress and NSSI/SA.

METHODS

The participants included 1149 adolescents (50.3% women; Mage = 12.86, SD = 0.69) who participated in three waves of data collection. Latent class growth models and cross-lagged panel models were used to identify subgroups of individuals and interactions between interpersonal stress and NSSI/SA.

RESULTS

Controlling for sex and age, compared to the low interpersonal stress class, the moderate to high and increasing classes have higher risks of NSSI and SA. Compared to adolescents in the low increasing feelings with high increasing avoidance class, those in the low increasing feelings with low decreasing avoidance class reported lower probabilities of NSSI and SA. Pain avoidance and painful feelings mediated the pathway from interpersonal stress to NSSI/SA, whereas pain arousal mediated the pathway from NSSI/SA to interpersonal stress.

CONCLUSIONS

Shared impact of interpersonal stress and distinct effects of psychological pain over time on maintaining and distinguishing self-harm behaviors were found. Adolescent crisis interventions should simultaneously focus on building social networks within the school context and regulating maladaptive minds.

Unveiling convergent and divergent intrinsic brain network alternations in depressed adolescents engaged in non-suicidal self-injurious behaviors with and without suicide attempts

AIMS

Limited understanding exists regarding the neurobiological mechanisms underlying non-suicidal self-injury (NSSI) and suicide attempts (SA) in depressed adolescents. The maturation of brain network is crucial during adolescence, yet the abnormal alternations in depressed adolescents with NSSI or NSSI+SA remain poorly understood.

METHODS

Resting-state functional magnetic resonance imaging data were collected from 114 depressed adolescents, classified into three groups: clinical control (non-self-harm), NSSI only, and NSSI+SA based on self-harm history. The alternations of resting-state functional connectivity (RSFC) were identified through support vector machine-based classification.

RESULTS

Convergent alterations in NSSI and NSSI+SA predominantly centered on the inter-network RSFC between the Limbic network and the three core neurocognitive networks (SalVAttn, Control, and Default networks). Divergent alterations in the NSSI+SA group primarily focused on the Visual, Limbic, and Subcortical networks. Additionally, the severity of depressive symptoms only showed a significant correlation with altered RSFCs between Limbic and DorsAttn or Visual networks, strengthening the fact that increased depression severity alone does not fully explain observed FC alternations in the NSSI+SA group.

CONCLUSION

Convergent alterations suggest a shared neurobiological mechanism along the self-destructiveness continuum. Divergent alterations may indicate biomarkers differentiating risk for SA, informing neurobiologically guided interventions.

The Effect of Bullying Victimization on Adolescent Non-Suicidal Self-Injury: The Mediating Roles of Alexithymia and Self-Esteem

Background & Aim

Non-suicidal self-injury (NSSI) in adolescents is a serious public health issue influenced by the interaction of multiple factors. The purpose of this study was to investigate the multiple mediating roles of alexithymia and self-esteem in the association between bullying victimization and NSSI in a sample of Chinese adolescents.

Methods

A survey of 1299 adolescents from two public middle schools in Henan Province, China, was undertaken. Data were collected using the Chinese version of the Delaware bullying victimization scale-student (DBVS-S), the Toronto Alexithymia-20 Scale (TAS-20-C), the Rosenberg self-esteem scale (RSES), and the adolescent self-injury questionnaire. Besides, we performed a structural equation modeling (SEM) with latent variables using AMOS 26.0 to examine the relationship between variables and the mediating effects.

Results

The SEM analysis found that not only can bullying victimization directly impact NSSI, but that alexithymia and self-esteem have a chain mediating effect in the association between bullying victimization and NSSI. This mediating effect contributed 22.47% to the total effect.

Conclusion

These findings validate bullying victimization, alexithymia, and low self-esteem are important variables that affect NSSI among Chinese adolescents. Educators need to implement some prevention and intervention strategies to ameliorate the campus atmosphere and adolescents' mental health aimed at avoiding NSSI behavior in adolescence.

The Effect of Mental Health Status and Family Function on Nonsuicidal Self-Injury: A Longitudinal Analysis of Chinese Children and Adolescents

Background

Nonsuicidal self-injury (NSSI) is an overwhelming social problem in children and adolescents. Focusing on the change of NSSI behavior, including onset, cessation, and maintenance, is crucial to developing effective prevention and intervention strategies. This study explored the effect of mental health status (depressive and anxiety symptoms) and family function on NSSI.

Methods

The study sample comprised 7554 children and adolescents based on the first two rounds of the Chengdu Positive Child Development (CPCD) dataset in China. Depressive and anxiety symptoms measured mental health status. The self-reported questionnaires also assessed NSSI behaviors and family function. The interrelationship between NSSI behaviors, mental health status, and family function was evaluated. Logistic regression and linear regression were performed to examine the interrelationship between mental health status, family function and NSSI behaviors. Sensitivity analysis was performed.

Results

In this study, 2167 (28.69%) participants reported NSSI at baseline and 2101 (27.81%) at follow-up. Depression, anxiety, and family function were salient influential factors in the prevalence, onset, and cessation of NSSI. Parents' accompaniment showed a significant effect on the prevalence of NSSI.

Conclusion

Depression, anxiety, family function, and parents' accompaniment are all associated with NSSI behaviors. Strategies targeting mental health status and family function could effectively protect children and adolescents from NSSI behaviors.

The effects of family environment cognition and its difference perceived by adolescents and their parents on the treatment effect of non-suicidal self-injury behaviors in adolescents: a 1-year prospective cohort study

Introduction

Family environment is the primary environment for adolescent growth and development, which is believed to have an important impact on the occurrence of non-suicidal self-injury (NSSI) behavior in adolescents. This study aimed to explore the effects of family environment cognition and cognitive differences perceived by adolescents and their parents on the treatment effects of NSSI in adolescents and to provide more potential perspectives for NSSI treatment.

Methods

A one-year prospective longitudinal sub-cohort investigation was carried out among 199 adolescents engaged in NSSI and one of their important guardians from the Longitudinal Psychosomatic Disease Study (LoPDS). The NSSI behaviors of adolescents were evaluated at 3 months, 6 months and 1 year after enrollment. The family environment scale (FES) and NSSI Behavior Questionnaire were used as assessment tools for family environment and adolescents NSSI behaviors. Multiple linear regression was used to investigate the role of family environment perception difference in the treatment effect of adolescent NSSI.

Results

After one year of follow-up, the perceived self-injury impulse score in recent 2 weeks, self-injury impulse frequency in recent 2 weeks, total number of self-injury in recent 2 weeks decreased significantly. The higher the adolescent family cohesion (Beta: 1.130, 95% CI: 0.886,1.373; p=0.032), parental family expressiveness (Beta: 0.818, 95% CI: 0.375,1.260; p=0.037) and parental family active-recreational orientation score (Beta: 0.609, 95% CI: 0.236,0.981; p=0.048), the better the treatment effect. However, higher adolescent family conflict (Beta: -0.838, 95% CI: -1.377,-0.298; p=0.024) were associated with lower treatment outcomes. The greater the cognitive difference between parents and adolescents in family cohesion (Beta: -1.307, 95% CI: -2.074,-0.539; p=0.014) and family conflict(Beta: -0.665, 95% CI: -0.919,-0.410; p=0.037), the worse the therapeutic effect of NSSI might be.

Discussion

There were certain differences in the cognition of family relationships between parents and adolescents, and subjective family relationship cognition and cognitive differences had a significant effect on the treatment effect of NSSI in adolescents. Helping them identify the cause of cognitive differences and conducting systematic family therapy from the points of difference may be another perspective to improve the treatment effect of NSSI in adolescents.

Strengthening Mental Health and Resilience Through Schools: Protocol for a Participatory Design Project

BACKGROUND

Mental health problems are a main contributor to the global burden of disease in children and young people within urban environments. In response, the potential of both school- and sport-based mental health promotion interventions has been advocated. However, there exists limited insights into how sport-based interventions can be integrated within school environment. Moreover, there is a need to consider children and young people's specific needs, challenges, and motivations when designing novel mental health promotion interventions.

OBJECTIVE

The Strengthening Mental Health and Resilience Through Schools (SMARTS) project aims to co-design an evidence-informed school-sport-based mental health promotion program. Specific objectives include (1) co-designing a multicomponent program, integrating sport sessions with class-based sessions, and complementing with educational modules for teachers and parents; (2) exploring how the mental health program can be implemented most effectively within the Brussels school system; and (3) conducting preliminary process and outcome testing of the program.

METHODS

A participatory design framework will be adopted to develop the program. This framework involves end users throughout the entire study process, from problem identification to intervention delivery and evaluation, while at the same time ensuring program development remains directly informed by the available scientific evidence.

RESULTS

Participant recruitment will commence in September 2023. The full project will be completed by March 2027.

CONCLUSIONS

With this intervention, we aim to provide a direct contribution to the promotion of children and young people's mental health within the Brussels school context. At a broader level, conducting and documenting this large participatory design project can, hopefully, inspire other researchers to tailor their mental health programs to specific populations.
