Risk and protective factors for childhood suicidality: a US population-based study

Sex-specific compensatory model of suicidal ideation: a population-based study (Urban HEART-2)

INTRODUCTION

Suicidal ideations (SI), also known as suicidal thoughts, refer to impulses, desires, and obsessions related to death. Prevalence of suicidal ideation was 14 percent. The current study assumed that identifying the true predictors of SI would allow for a greater understanding of suicide risk.

METHODS

In this cross-sectional population-based study, 17,644 residents aged from 15 to 90 years were selected through a multi-stage sampling method from 22 districts of Tehran. Using hypothesized causal models, the pathways through which various variables influenced the components of SI were identified. Also, the applicability of the compensatory and risk-protective models of resiliency for the prediction of SI was tested by using the interaction multiple regression analyses.

RESULTS

SI was experienced by 13.44% of the study population. SI was more prevalent with individuals between the ages of 15 to 24. There are no differences between men and women when covariate analysis is used. The significant predictions by anxiety and physical activity (moderate) indicate support for the compensatory model for male and female, while the significant prediction by those indicates support for the risk-protective model for females.

CONCLUSION

PA would both lessen the detrimental impact of anxiety on suicidal thoughts and potentially reduce the probability of SI. It's important to develop and evaluate PA-enhancing treatments, especially for woman who are experiencing anxiety.

Trauma Exposure Moderates the Link Between Cognitive Flexibility and Suicide Risk in Pre-Adolescent Children

OBJECTIVES

Trauma exposure (TE) and cognitive flexibility (CF) are risk factors for self-injurious thoughts and behaviors (SITBs). However, it is unknown whether these risk factors contribute to mechanisms associated with distinct categories of SITBs. The current study examined the potential moderating role of TE in the relationships between CF and multiple SITBs, including active suicidal ideation (SI), passive SI, non-suicidal self-injury (NSSI), and history of suicide attempt (SA), among pre-adolescent children.

METHODS

A total of 11,326 children from the Adolescent Brain Cognitive Development study were included in the present study. SITBs and TE were measured by the Kiddy Schedule for Affective Disorder and Schizophrenia (KSADS). CF was measured using the NIH Cognitive Toolbox.

RESULTS

Cumulative TE moderated the relationship of CF to active SI. Higher CF was associated with lower odds of current SI in children with a single lifetime TE, but not in children without trauma or with two or more TE. As a main effect, two or more TE predicted higher odds of active SI, passive SI, and lifetime SA, but not NSSI. Higher CF was associated with lower odds of passive SI, with effects not moderated by trauma exposure.

CONCLUSION

The current results clarify previously inconsistent findings about the relationship of CF to SI by identifying cumulative TE as a moderator. CF served as a protective factor against SI, but only in children with a single lifetime trauma. Implications for screening and treatment targets of children at risk for distinct categories of SITBs are discussed.

Classification of Suicide Attempt Risk Using Environmental and Lifestyle Factors in 3 Large Youth Cohorts

Importance

Suicide is the third-leading cause of death among US adolescents. Environmental and lifestyle factors influence suicidal behavior and can inform risk classification, yet quantifying and incorporating them in risk assessment presents a significant challenge for reproducibility and clinical translation.

Objective

To quantify the aggregate contribution of environmental and lifestyle factors to youth suicide attempt risk classification.

Design, Setting, and Participants

This was a cohort study in 3 youth samples: 2 national longitudinal cohorts from the US and the UK and 1 clinical cohort from a tertiary pediatric US hospital. An exposome-wide association study (ExWAS) approach was used to identify risk and protective factors and compute aggregate exposomic scores. Logistic regression models were applied to test associations and model fit of exposomic scores with suicide attempts in independent data. Youth from the Adolescent Brain Cognitive Development (ABCD) study, the UK Millennium Cohort Study (MCS), and the Children's Hospital of Philadelphia emergency department (CHOP-ED) were included in the study.

Exposures

A single-weighted exposomic score that sums significant risk and protective environmental/lifestyle factors.

Main Outcome and Measure

Self-reported suicide attempt.

Results

A total of 40 364 youth were included in this analysis: 11 564 from the ABCD study (3 waves of assessment; mean [SD] age, 12.0 [0.7] years; 6034 male [52.2%]; 344 attempted suicide [3.0%]; 1154 environmental/lifestyle factors were included in the ABCD study), 9000 from the MCS cohort (mean [SD] age, 17.2 [0.3] years; 4593 female [51.0%]; 661 attempted suicide [7.3%]; 2864 environmental/lifestyle factors were included in the MCS cohort), and 19 800 from the CHOP-ED cohort (mean [SD] age, 15.3 [1.5] years; 12 937 female [65.3%]; 2051 attempted suicide [10.4%]; 36 environmental/lifestyle factors were included in the CHOP-ED cohort). In the ABCD discovery subsample, ExWAS identified 99 risk and protective exposures significantly associated with suicide attempt. A single weighted exposomic score that sums significant risk and protective exposures was associated with suicide attempt in an independent ABCD testing subsample (odds ratio [OR], 2.2; 95% CI, 2.0-2.6; P < .001) and explained 17.6% of the variance (based on regression pseudo-R2) in suicide attempt over and above that explained by age, sex, race, and ethnicity (2.8%) and by family history of suicide (6.3%). Findings were consistent in the MCS and CHOP-ED cohorts (explaining 22.6% and 19.3% of the variance in suicide attempt, respectively) despite clinical, demographic, and exposure differences. In all cohorts, compared with youth at the median quintile of the exposomic score, youth at the top fifth quintile were substantially more likely to have made a suicide attempt (OR, 4.3; 95% CI, 2.6-7.2 in the ABCD study; OR, 3.8; 95% CI, 2.7-5.3 in the MCS cohort; OR, 5.8; 95% CI, 4.7-7.1 in the CHOP-ED cohort).

Conclusions and Relevance

Results suggest that exposomic scores of suicide attempt provided a generalizable method for risk classification that can be applied in diverse samples from clinical or population settings.

Identifying behaviour-related and physiological risk factors for suicide attempts in the UK Biobank

Suicide is a global public health challenge, yet considerable uncertainty remains regarding the associations of both behaviour-related and physiological factors with suicide attempts (SA). Here we first estimated polygenic risk scores (PRS) for SA in 334,706 UK Biobank participants and conducted phenome-wide association analyses considering 2,291 factors. We identified 246 (63.07%) behaviour-related and 200 (10.41%, encompassing neuroimaging, blood and metabolic biomarkers, and proteins) physiological factors significantly associated with SA-PRS, with robust associations observed in lifestyle factors and mental health. Further case-control analyses involving 3,558 SA cases and 149,976 controls mirrored behaviour-related associations observed with SA-PRS. Moreover, Mendelian randomization analyses supported a potential causal effect of liability to 58 factors on SA, such as age at first intercourse, neuroticism, smoking, overall health rating and depression. Notably, machine-learning classification models based on behaviour-related factors exhibited high discriminative accuracy in distinguishing those with and without SA (area under the receiver operating characteristic curve 0.909 ± 0.006). This study provides comprehensive insights into diverse risk factors for SA, shedding light on potential avenues for targeted prevention and intervention strategies.

Risk factors and their association network for young adults' suicidality: a cross-sectional study

BACKGROUND

Understanding the intricate influences of risk factors contributing to suicide among young individuals remains a challenge. The current study employed interpretable machine learning and network analysis to unravel critical suicide-associated factors in Chinese university students.

METHODS

A total of 68,071 students were recruited between Sep 2016 and Sep 2020 in China. Students reported their lifetime experiences with suicidal thoughts and behaviors, categorized as suicide ideation (SI), suicide plan (SP), and suicide attempt (SA). We assessed 36 suicide-associated factors including psychopathology, family environment, life events, and stigma. Local interpretations were provided using Shapley additive explanation (SHAP) interaction values, while a mixed graphical model facilitated a global understanding of their interplay.

RESULTS

Local explanations based on SHAP interaction values suggested that psychoticism and depression severity emerged as pivotal factors for SI, while paranoid ideation strongly correlated with SP and SA. In addition, childhood neglect significantly predicted SA. Regarding the mixed graphical model, a hierarchical structure emerged, suggesting that family factors preceded proximal psychopathological factors, with abuse and neglect retaining unique effects. Centrality indices derived from the network highlighted the importance of subjective socioeconomic status and education in connecting various risk factors.

CONCLUSIONS

The proximity of psychopathological factors to suicidality underscores their significance. The global structures of the network suggested that co-occurring factors influence suicidal behavior in a hierarchical manner. Therefore, prospective prevention strategies should take into account the hierarchical structure and unique trajectories of factors.

Exploring risk factors and their differences on suicidal ideation and suicide attempts among depressed adolescents based on decision tree model

BACKGROUND

Suicide has been recognized as a major global public health issue. Depressed adolescents are more prone to experiencing it. We explore risk factors and their differences on suicidal ideation and suicide attempts to further enhance our understanding of suicidal behavior.

METHODS

2343 depressed adolescents aged 12-18 from 9 provinces/cities in China participated in this cross-sectional study. We utilized decision tree model, incorporating 32 factors encompassing participants' suicidal behavior. The feature importance of each factor was measured using Gini coefficients.

RESULTS

The decision tree model demonstrated a good fit with high accuracy (SI = 0.86, SA = 0.85 and F-Score (SI = 0.85, SA = 0.83). The predictive importance of each factor varied between groups with suicidal ideation and with suicide attempts. The most significant risk factor in both groups was depression (SI = 16.7 %, SA = 19.8 %). However, factors such as academic stress (SI = 7.2 %, SA = 1.6 %), hopelessness (SI = 9.1 %, SA = 5.0 %), and age (SI = 7.1 %, SA = 3.2 %) were more closely associated with suicidal ideation than suicide attempts. Factors related to the schooling status (SI = 3.5 %, SA = 10.1 %), total years of education (SI = 2.6 %, SA = 8.6 %), and loneliness (SI = 2.3 %, SA = 7.4 %) were relatively more important in the suicide attempt stage compared to suicidal ideation.

LIMITATIONS

The cross-sectional design limited the ability to capture changes in suicidal behavior among depressed adolescents over time. Possible bias may exist in the measurement of suicidal ideation.

CONCLUSION

The relative importance of each risk factor for suicidal ideation and attempted suicide varies. These findings provide further empirical evidence for understanding suicide behavior. Targeted treatment measures should be taken for different stages of suicide in clinical interventions.

Prediction of suicidal ideation among preadolescent children with machine learning models: A longitudinal study

BACKGROUND

Machine learning (ML) has been widely used to predict suicidal ideation (SI) in adolescents and adults. Nevertheless, studies of accurate and efficient models of SI prediction with preadolescent children are still needed because SI is surprisingly prevalent during the transition into adolescence. This study aimed to explore the potential of ML models to predict SI among preadolescent children.

METHODS

A total of 4691 Chinese children (54.89 % boys, Mage = 10.92 at baseline) and their parents completed relevant measures at baseline and the children provided 6-month follow-up data for SI. The current study compared four ML models: Random Forest (RF), Decision Tree (DT), Support Vector Machine (SVM), and Multilayer Perceptron (MLP), to predict SI and to identify variables with predictive value based on the best-performing model among Chinese preadolescent children.

RESULTS

The RF model achieved the highest discriminant performance with an AUC of 0.92, accuracy of 0.93 (balanced accuracy = 0.88). The factors of internalizing problems, externalizing problems, neuroticism, childhood maltreatment, and subjective well-being in school demonstrated the highest values in predicting SI.

CONCLUSION

The findings of this study suggested that ML models based on the observation and assessment of children's general characteristics and experiences in everyday life can serve as convenient screening and evaluation tools for suicide risk assessment among Chinese preadolescent children. The findings also provide insights for early intervention.

Triple Interactions Between the Environment, Brain, and Behavior in Children: An ABCD Study

BACKGROUND

Environmental exposures play a crucial role in shaping children's behavioral development. However, the mechanisms by which these exposures interact with brain functional connectivity and influence behavior remain unexplored.

METHODS

We investigated the comprehensive environment-brain-behavior triple interactions through rigorous association, prediction, and mediation analyses, while adjusting for multiple confounders. Particularly, we examined the predictive power of brain functional network connectivity (FNC) and 41 environmental exposures for 23 behaviors related to cognitive ability and mental health in 7655 children selected from the Adolescent Brain Cognitive Development (ABCD) Study at both baseline and follow-up.

RESULTS

FNC demonstrated more predictability for cognitive abilities than for mental health, with cross-validation from the UK Biobank study (N = 20,852), highlighting the importance of thalamus and hippocampus in longitudinal prediction, while FNC+environment demonstrated more predictive power than FNC in both cross-sectional and longitudinal prediction of all behaviors, especially for mental health (r = 0.32-0.63). We found that family and neighborhood exposures were common critical environmental influencers on cognitive ability and mental health, which can be mediated by FNC significantly. Healthy perinatal development was a unique protective factor for higher cognitive ability, whereas sleep problems, family conflicts, and adverse school environments specifically increased risk of poor mental health.

CONCLUSIONS

This work revealed comprehensive environment-brain-behavior triple interactions based on the ABCD Study, identified cognitive control and default mode networks as the most predictive functional networks for a wide repertoire of behaviors, and underscored the long-lasting impact of critical environmental exposures on childhood development, in which sleep problems were the most prominent factors affecting mental health.

Predicting Lifetime Suicide Attempts in a Community Sample of Adolescents Using Machine Learning Algorithms

Suicide is a major global health concern and a prominent cause of death in adolescents. Previous research on suicide prediction has mainly focused on clinical or adult samples. To prevent suicides at an early stage, however, it is important to screen for risk factors in a community sample of adolescents. We compared the accuracy of logistic regressions, elastic net regressions, and gradient boosting machines in predicting suicide attempts by 17-year-olds in the Millennium Cohort Study (N = 7,347), combining a large set of self- and other-reported variables from different categories. Both machine learning algorithms outperformed logistic regressions and achieved similar balanced accuracies (.76 when using data 3 years before the self-reported lifetime suicide attempts and .85 when using data from the same measurement wave). We identified essential variables that should be considered when screening for suicidal behavior. Finally, we discuss the usefulness of complex machine learning models in suicide prediction.

Protective Associations between Supportive Environment and Suicidality among Minority and Majority Adolescents

OBJECTIVE

To examine the association between supportive environments and adolescent suicidal behavior, especially among marginalized minority groups.

METHODS

Participants included 12,196 middle and 16,981 high school students who completed the 2019 Vermont Youth Risk Behavior Survey. Multiple logistic regression models were used to assess the association between three protective factors that were part of a supportive environment (feeling like they matter to people in their community, usually eating dinner at home, having a trusted adult) and suicidality (plan or attempt), controlling for key demographics (sex, sexual orientation, gender identity, and race/ethnicity). Moderating effects of demographics were also explored.

RESULTS

All supportive environment variables were protective of making a suicide plan and making a suicide attempt (ORs < 0.75, p-values < 0.005). Students of minority identities were significantly more likely to make a suicide plan (middle school ORs: 1.34-3.51, p-values < 0.0005; high school ORs: 1.19-3.38, p-values < 0.02) and attempt suicide (middle school ORs: 1.42-3.72, p-values < 0.006; high school ORs: 1.38-3.25, p-values < 0.0005) compared to students with majority demographic characteristics. Generally, the associations between having a supportive environment and suicidality did not vary within sexual orientation, gender identify, or race/ethnicity subgroups, suggesting that these supportive environment factors were more universally protective. However, a few associations were stronger among students in the majority demographic groups.

CONCLUSIONS

These data suggest that having a supportive environment is protective of suicidality for adolescents from both majority and minority demographic groups.

Suicidality risk in children and adolescents with externalizing disorders: symptoms profiles at high risk and the moderating role of dysregulated family relationships

Children and adolescents with externalizing disorders are at risk for suicidal ideation or behavior. Factors that put them at risk could be symptoms related or facilitated by their environment. We evaluated the links of symptoms profiles with suicidality, and the effects of family relationship characteristics on these links. Latent profile analysis was used to subgroup participants referred for ADHD assessment (n = 1249, aged 6-17) based on their externalizing and internalizing symptoms. Self- and parent-reported child suicidal ideation (S-SI, P-SI), and parent-reported self-harm behavior (P-SHB) were compared across profiles. The moderating effects of parent-reported marital conflict and parenting practices were examined. A four-profile model showed optimal fit. Participants of the Low Symptoms profile followed by the Inattentive-Hyperactive/Impulsive profile showed lower P-SI compared to those of the Irritable-Defiant and the Conduct Problems profiles. Low Symptoms participants also reported lower S-SI compared to those of the Inattentive-Hyperactive/Impulsive and the Irritable-Defiant profiles. Participants of the Irritable-Defiant and the Conduct Problems profiles had higher P-SHB compared to the Low Symptoms and the Inattentive-Hyperactive/Impulsive participants. Dysregulated marital conflict practices were associated with greater increase in P-SI in all profiles compared to the Low Symptoms profile. Aggressive marital conflict practices were associated with increased P-SHB in the Conduct Problems profile compared to the Inattentive-Hyperactive/Impulsive profile. Children and adolescents with irritability and defiance symptoms with or without conduct problems show higher risk for suicidal ideation and behavior compared to those with ADHD symptoms alone. Dysregulated and aggressive marital conflict practices might pose additional suicidality risk in children and adolescents with disruptive behavior.

A structural equation modeling approach using behavioral and neuroimaging markers in major depressive disorder

Major depressive disorder (MDD) has consistently proven to be a multifactorial and highly comorbid disease. Despite recent depression-related research demonstrating causalities between MDD-related factors and a small number of variables, including brain structural changes, a high-statistical power analysis of the various factors is yet to be conducted. We retrospectively analyzed data from 155 participants (84 healthy controls and 71 patients with MDD). We used magnetic resonance imaging and diffusion tensor imaging data, scales assessing childhood trauma, depression severity, cognitive dysfunction, impulsivity, and suicidal ideation. To simultaneously evaluate the causalities between multivariable, we implemented two types of MDD-specified structural equation models (SEM), the behavioral and neurobehavioral models. Behavioral SEM showed significant results in the MDD group: Comparative Fit Index [CFI] = 1.000, Root Mean Square Error of Approximation [RMSEA]) = 0.000), with a strong correlation in the scales for childhood trauma, depression severity, suicidal ideation, impulsivity, and cognitive dysfunction. Based on behavioral SEM, we established neurobehavioral models showing the best-fit in MDD, especially including the right cingulate cortex, central to the posterior corpus callosum, right putamen, pallidum, whole brainstem, and ventral diencephalon, including the thalamus (CFI >0.96, RMSEA <0.05). Our MDD-specific model revealed that the limbic-associated regions are strongly connected with childhood trauma rather than depression severity, and that they independently affect suicidal ideation and cognitive dysfunction. Furthermore, cognitive dysfunction could affect impulsivity.

Suicide prevention: Introducing the Lothian Safekeeping Plan© for parents as a clinical innovation for use alongside safety plans for children and young people

TOPIC

Internationally, preventing suicide in children and young people is a priority and there are a range of preventative approaches available for health professionals to use, including brief interventions. Safety planning is one such brief intervention. Safety plans have long been recommended for use with young people who are suicidal but, these were initially developed for adults. A recent scoping review revealed safety plans need to be tailored to children and young people. This review also identified an important practice gap, that parents also require plans supporting them to keep their child safe.

PURPOSE

This paper highlights how a Scottish clinical child and adolescent mental health setting in the UK's National Health Service developed and implemented evidence-based safety plans for suicidality-the Lothian Safety Plan for young people and the Lothian Safekeeping Plan for parents. This paper outlines both plans and gives recommendations for their use by healthcare professionals. The parental Lothian Safekeeping Plan is discussed in more depth as this is a novel intervention.

CONCLUSION

The Lothian Safekeeping Plan is a clinically led evidence-based practice innovation. It is a specific suicide prevention plan for use by parents as an additional, complementary, and enhanced resource to the Lothian Safety Plan for young people. It is recommended that healthcare professionals also use a parental safety plan when supporting young people presenting with suicidal crisis. Further research is needed to evaluate the impact of these plans.

Brain structural and functional signatures of multi-generational family history of suicidal behaviors in preadolescent children

Parent-child transmission of suicidal behaviors has been extensively studied, but the investigation of a three-generation family suicide risk paradigm remains limited. In this study, we aimed to explore the behavioral and brain signatures of multi-generational family history of suicidal behaviors (FHoS) in preadolescents, utilizing a longitudinal design and the dataset from Adolescent Brain and Cognitive DevelopmentSM Study (ABCD Study®), which comprised 4 years of data and includes a total of 9,653 preadolescents. Our findings revealed that multi-generational FHoS was significantly associated with an increased risk of problematic behaviors and suicidal behaviors (suicide ideation and suicide attempt) in offspring. Interestingly, the problematic behaviors were further identified as a mediator in the multi-generational transmission of suicidal behaviors. Additionally, we observed alterations in brain structure within superior temporal gyrus (STG), precentral/postcentral cortex, posterior parietal cortex (PPC), cingulate cortex (CC), and planum temporale (PT), as well as disrupted functional connectivity of default mode network (DMN), ventral attention network (VAN), dorsal attention network (DAN), fronto-parietal network (FPN), and cingulo-opercular network (CON) among preadolescents with FHoS. These results provide compelling longitudinal evidence at the population level, highlighting the associations between multi-generational FHoS and maladaptive behavioral and neurodevelopmental outcomes in offspring. These findings underscore the need for early preventive measures aimed at mitigating the familial transmission of suicide risk and reducing the global burden of deaths among children and adolescents.

The Relationship between Childhood Abuse and Suicidal Ideation among Chinese College Students: The Mediating Role of Core Self-Evaluation and Negative Emotions

Childhood abuse is a significant risk factor for suicidal ideation. However, the underlying mediation mechanism necessitates further exploration. This study investigated the mediating role of core self-evaluation and negative emotions in the relationship between childhood abuse and suicide ideation in young adults. A sample of 3103 college students from 11 universities across 8 provinces in China was analyzed. Childhood abuse, core self-evaluation, negative emotions, and suicidal ideation were assessed using the Childhood Trauma Questionnaire (CTQ-CF), Core Self-Evaluation Scale, Affect Scale, and Beck Suicidal Ideation Scale (BSI-CV), respectively. Data analysis was conducted using SPSS 19.0 and SPSS Macro Process. We found that high scores for childhood abuse were associated with elevated levels of suicidal ideation, whereas low scores for core self-evaluation were closely linked to heightened levels of negative emotions and suicidal ideation. Furthermore, core self-evaluation and negative emotions mediated the relationship between childhood abuse and suicidal ideation through three significant paths. The results demonstrate that childhood abuse can directly impact suicidal ideation in young adulthood and indirectly influence suicidal ideation by affecting core self-evaluation and negative emotions. They suggest that addressing core self-evaluation and negative emotions in individuals who have experienced childhood abuse may help prevent or treat suicidal ideation.

Suicidal Thoughts and Trajectories of Psychopathological and Behavioral Symptoms in Adolescence

Importance

The suicidal risk of psychopathology in adolescence is suggested to differ based on its longitudinal trajectory, but the comorbidity of these symptom trajectories has not been well examined. This study comprehensively clustered trajectories of multiple psychopathological and behavioral symptoms and examined their associations with suicidal thoughts in adolescence.

Objective

To determine which categories and trajectories of psychopathological and behavioral symptoms are associated with suicidal thoughts in adolescence, accounting for comorbid symptoms.

Design, Setting, and Participants

This population-based cohort study in Japan used data from the Tokyo Teen Cohort (TTC) study, which was established in 2012 and is currently ongoing. Data from 3 waves of surveys conducted at ages 10, 12, and 16 years from October 2012 to September 2021 were used. Of the adolescents in the cohort, participants with at least 2 evaluations of psychopathological and behavioral symptoms were included. Data were analyzed from December 2022 to March 2023.

Exposure

Latent class growth analysis was used to cluster the trajectory of each psychopathological and behavioral symptom.

Main Outcomes and Measures

The associations between symptom trajectories and suicidal thoughts at age 16 were examined. Suicidal thoughts were assessed using a self-report questionnaire. Psychopathological and behavioral symptoms were assessed using the 8 subscale scores of the caregiver-report Child Behavior Checklist.

Results

This study included 2780 adolescents (1306 female participants [47.0%]). Of the 1920 adolescents with data on suicidal thoughts, 158 (8.2%) had suicidal thoughts. The median (IQR) age was 10.2 (10.0-10.3) years at the first evaluation, 11.9 (11.8-12.1) years at the second evaluation, and 16.3 (16.1-16.5) years at the last evaluation. The clustering pattern of trajectories varied depending on symptom categories. After adjusting for each symptom trajectory and confounders, adolescents with persistent high withdrawn symptoms (odds ratio [OR], 1.88; 95% CI, 1.10-3.21) and those with increasing somatic symptoms (OR, 1.97; 95% CI, 1.16-3.34) had a significantly higher risk of suicidal thoughts than adolescents without these symptoms. There was no interaction between these symptom trajectories and the risk of suicidal thoughts.

Conclusions and Relevance

This cohort study found that persistent withdrawn symptoms and increasing somatic symptoms during early to midadolescence were associated with an increased risk of suicidal thoughts in midadolescence, even after accounting for comorbid symptoms and confounders. Attention should be paid to the suicidal risk associated with these symptoms, particularly when they persist or increase in the longitudinal follow-up.

Childhood Trauma and Self-harm in Youths with Bipolar Disorders

BACKGROUND

Bipolar disorders (BD) in youth are associated with a high risk of self-harm behaviors. Childhood trauma (CT) is a relevant environmental stressor that is related to both BD diagnosis and self-harm in adulthood. It is not yet established whether CT may impact self-harm risk in youth. Therefore, the aim of this study was to investigate the distribution patterns of CT in youth BD with and without self-harm.

METHODS

We assessed 273 participants (aged 13-25 years), 96 youths with BD according to DSM-5 criteria and 177 healthy controls (HC). History of CT was obtained using the Childhood Trauma Questionnaire (CTQ). The association between CT and self-harm was tested using multivariate statistical models.

RESULTS

Over 45% of participants with BD reported lifetime self-harm. The BD Self-harm group reported more emotional abuse, emotional neglect, sexual abuse, and physical abuse than HC. The BD No-Self-harm group reported more emotional abuse than HC. The BD Self-harm group reported more emotional abuse and neglect than the BD No-Self-harm group. The BD Self-harm group also reported separated parents, hospitalizations, smoking, use of antiepileptics, antipsychotics and lithium. Emotional abuse was an independent predictor of self-harm in youths with BD.

CONCLUSION

Findings support the importance of assessing CT, in particular emotional abuse, in youth with BD at risk for self-harm.

Patterns of Social Determinants of Health and Child Mental Health, Cognition, and Physical Health

Importance

Social determinants of health (SDOH) influence child health. However, most previous studies have used individual, small-set, or cherry-picked SDOH variables without examining unbiased computed SDOH patterns from high-dimensional SDOH factors to investigate associations with child mental health, cognition, and physical health.

Objective

To identify SDOH patterns and estimate their associations with children's mental, cognitive, and physical developmental outcomes.

Design, Setting, and Participants

This population-based cohort study included children aged 9 to 10 years at baseline and their caregivers enrolled in the Adolescent Brain Cognitive Development (ABCD) Study between 2016 and 2021. The ABCD Study includes 21 sites across 17 states.

Exposures

Eighty-four neighborhood-level, geocoded variables spanning 7 domains of SDOH, including bias, education, physical and health infrastructure, natural environment, socioeconomic status, social context, and crime and drugs, were studied. Hierarchical agglomerative clustering was used to identify SDOH patterns.

Main Outcomes and Measures

Associations of SDOH and child mental health (internalizing and externalizing behaviors) and suicidal behaviors, cognitive function (performance, reading skills), and physical health (body mass index, exercise, sleep disorder) were estimated using mixed-effects linear and logistic regression models.

Results

Among 10 504 children (baseline median [SD] age, 9.9 [0.6] years; 5510 boys [52.5%] and 4994 girls [47.5%]; 229 Asian [2.2%], 1468 Black [14.0%], 2128 Hispanic [20.3%], 5565 White [53.0%], and 1108 multiracial [10.5%]), 4 SDOH patterns were identified: pattern 1, affluence (4078 children [38.8%]); pattern 2, high-stigma environment (2661 children [25.3%]); pattern 3, high socioeconomic deprivation (2653 children [25.3%]); and pattern 4, high crime and drug sales, low education, and high population density (1112 children [10.6%]). The SDOH patterns were distinctly associated with child health outcomes. Children exposed to socioeconomic deprivation (SDOH pattern 3) showed the worst health profiles, manifesting more internalizing (β = 0.75; 95% CI, 0.14-1.37) and externalizing (β = 1.43; 95% CI, 0.83-2.02) mental health problems, lower cognitive performance, and adverse physical health.

Conclusions

This study shows that an unbiased quantitative analysis of multidimensional SDOH can permit the determination of how SDOH patterns are associated with child developmental outcomes. Children exposed to socioeconomic deprivation showed the worst outcomes relative to other SDOH categories. These findings suggest the need to determine whether improvement in socioeconomic conditions can enhance child developmental outcomes.

Suicidal Ideation and Non-Suicidal Self-Injury Following Early Childhood Psychotic Experiences in Preadolescent Children at Familial High Risk of Schizophrenia or Bipolar Disorder-The Danish High Risk and Resilience Study, VIA 11

BACKGROUND AND HYPOTHESIS

Suicide is a leading cause of death in youth and is often preceded by suicidal ideation (SI) and non-suicidal self-injury (NSSI). Identifying early markers of risk for SI and NSSI could improve timely identification of at-risk individuals.

STUDY DESIGN

Children (mean age 11.9, SD 0.2) at familial high risk of schizophrenia (N = 171), or bipolar disorder (N = 104), and controls (N = 174) were assessed for psychotic experiences (PE), SI, NSSI, and Axis I mental disorders in face-to-face interviews in early and middle childhood (age 7 and 11).

STUDY RESULTS

Having 2 types of early childhood PE predicted middle childhood SI after accounting for previous SI, NSSI, and mental disorders (OR 2.8, 95% CI 1.1-6.9; P = .03). Two PE predicted NSSI (OR 3.0, 95% CI 1.2-7.7; P = .02) in excess of previous SI, NSSI, mental disorders, and familial risk. Persistent and incident PE predicted SI (OR 3.2, 95% CI, 1.1-8.8; P = .03; OR 3.8, 95% CI, 1.3-11.5; P = .02) in the fully adjusted model. Nineteen percent of children with persistent PE reported middle childhood SI vs 3.8% of those who never reported PE. In children with early childhood mental disorders, those who reported 2 PE had 4.4-fold increased odds of later SI (95% CI, 1.2-16.7; P = .03) after adjustments. PE were nondifferentially associated with outcomes across familial risk groups.

CONCLUSIONS

Early childhood PE index elevated risk for subsequent SI and NSSI beyond what can be attributed to presence of mental disorders. Mental health screenings and clinical assessments should include early childhood PE.

Long-term Effects of the Family Check-Up on Suicidality in Childhood and Adolescence: Integrative Data Analysis of Three Randomized Trials

This study employed integrative data analysis techniques to examine the long-term effects of the family check-up (FCU) on changes in youth suicide risk using three randomized prevention trials, including one trial initiated in early childhood and two initiated in early adolescence. Data were harmonized across studies using moderated nonlinear factor analysis, and intervention effects were tested using an autoregressive latent trajectory model examining changes in suicide risk across long-term follow-up. Across trials, significant long-term effects of the FCU on reductions in suicide risk were observed, although differences between intervention and control group trajectories declined over time. No moderation of intervention effects was observed by youth gender or race/ethnicity or across samples. While results offer further support for the benefits of the FCU for suicide risk reduction, they also suggest that such effects may wane over time, underscoring the need for continued development of the FCU to enhance longer-term durability of effects on suicide-related behaviors.

Health-Related Quality of Life and Mental Health of Children with Embryonal Abdominal Tumors

(1) Background: Embryonal abdominal tumors are one of the most common entities of solid childhood cancer. The present study investigates the Health-Related Quality of Life (HRQoL) and the mental health of children to obtain a comprehensive picture of their health status and uncover a possible gap in healthcare. (2) Methods: The sample consisted of 54 children who were treated for embryonal abdominal tumors and a control group of 46 children who received uncomplicated outpatient surgery. The HRQoL and the mental health were assessed by the parent proxy reports of the questionnaires Pediatric Quality of Life Inventory (PedsQL) and Strengths and Difficulties Questionnaire (SDQ). (3) Results: Children with embryonal abdominal tumors showed significantly lower HRQoL and mental health values compared to the norm data. The index group showed lower values in the social subscales of HRQoL and mental health compared to the control group. (4) Conclusions: Embryonal abdominal tumors affect the well-being of children. There is still a gap in healthcare due to children's HRQoL and mental health, especially regarding social development. It is essential to further advance the psychological care of children and improve their chances to develop social relationships.

Psychotic-Like Experiences and Suicidal Ideation Among Adolescents: The Chain Mediating Role of Insomnia Symptoms and Resilience

Background

Individuals who experience psychotic-like experiences (PLEs) are at significant risk of suicide-related behaviors. This two-wave longitudinal study aimed to investigate the relationships among PLEs, insomnia symptoms, resilience, and suicidal ideation (SI) among adolescents.

Methods

A total of 2231 college students [mean age (standard deviation) = 20.02 (1.39) years] completed two web-based surveys. Participants completed self-report measures of sample characteristics, PLEs, insomnia symptoms, resilience, and SI.

Results

The findings indicated a significantly positive correlation between PLEs and SI that was sequentially mediated by insomnia symptoms and resilience. Furthermore, insomnia symptoms and resilience played a chain-mediating role between PLEs and adolescent SI.

Conclusion

These findings suggest potential mechanism for the PLEs-SI link, which helps us better understand how PLEs can influence individual SI and provides important information for early prevention.

Correlation between negative life events and suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture

OBJECTIVE

To investigate the incidence of suicide attempts among adolescents with HIV/AIDS in Liangshan Prefecture, Sichuan Province, as well as the correlation between negative life events, sleep, exercise, drug therapy and suicide attempts.

METHODS

A total of 180 Yi adolescents aged 11-19 years with HIV/AIDS in a county of Liangshan Prefecture, Sichuan Province, China, were investigated by census. The main outcome indicators included the incidence of suicide attempts and whether negative life events, sleep, exercise, drug therapy and other factors were related to suicide attempts.

RESULTS

We found that the incidence rate of suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture was 13.9%. Negative life events were a risk factor for suicide attempts (OR = 1.047, p < 0.001, 95% CI 1.027-1.067). In the factors of negative life events, adaptation was a risk factor for suicide attempts (OR = 1.203, p = 0.026, 95% CI 1.022-1.416), and academic pressure showed a tendency to be a risk factor for suicide attempts (OR = 1.149, p = 0.077, 95% CI 0.985-1.339). However, the punishment factor, interpersonal stress factor and loss factor had no significant correlation with suicide attempts. There was no significant correlation between sleep, exercise, drug therapy and suicide attempts.

CONCLUSION

The proportion of suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture is high and should be considered. Negative life events are independent risk factors for suicide attempts, and it is necessary to strengthen the screening and early intervention for suicide attempts in HIV/AIDS adolescents with definite negative life events.

Online harms? Suicide-related online experience: a UK-wide case series study of young people who die by suicide

BACKGROUND

Few studies have examined online experience by young people who die by suicide.

METHODS

A 3-year UK-wide consecutive case series of all young people aged 10-19 who died by suicide, based on national mortality data. We extracted information on the antecedents of suicide of 544 of these 595 deaths (91%) from official investigations, mainly inquests.

RESULTS

Suicide-related online experience was reported in 24% (n = 128/544) of suicide deaths in young people between 2014 and 2016, equivalent to 43 deaths per year, and was more common in girls than boys (OR 1.87, 95% CI 1.23-2.85, p = 0.003) and those identifying as LGBT (OR 2.35, 95% CI 1.10-5.05, p = 0.028). Searching for information about method was most common (n = 68, 13%), followed by posting suicidal ideas online (n = 57, 10%). Self-harm, bereavement (especially by suicide), social isolation, and mental and physical ill-health were more likely in those known to have suicide-related online experience compared to those who did not. 29 (5%) were bullied online, more often girls (OR 2.84, 1.34-6.04, p = 0.007). Online bullying often accompanied face-to-face bullying (n = 16/29, 67%).

CONCLUSIONS

Suicide-related online experience is a common, but likely underestimated, antecedent to suicide in young people. Although its causal role is unclear, it may influence suicidality in this population. Mental health professionals should be aware that suicide-related online experience - not limited to social media - is a potential risk for young patients, and may be linked to experiences offline. For public health, wider action is required on internet regulation and support for children and their families.

The experiences of emergency hospital care among adolescents and young adults with self-harm: A systematic review and thematic synthesis of qualitative evidence

QUESTION

The incidence of self-injurious behavior in adolescents and young adults is on the rise. Seeking care in the emergency department after self-injurious behavior is one way they signal for help. The purpose of this systematic evaluation was to synthesize the best available qualitative research evidence on young people's experiences of emergency department visits following self-harm behaviors and their need for emergency medical services.

STUDY SELECTION AND ANALYSIS

Eleven databases were retrieved with predefined search terms from database construction to February 4, 2022. Literature was screened according to inclusion and exclusion criteria and quality assessment.

FINDINGS

Eleven studies yielded fifty-five findings that were summarized into eight categories and aggregated into three composite statements: (1) positive emergency department experience; (2) negative emergency department experience; and (3) desire for help.

CONCLUSIONS

Young people with a history of self-injurious behavior have a mixed sense of experience in the emergency department. The sense of negative experience makes patients feel dissatisfied and disappointed with healthcare services, and positive experiences can help them seek further help. The emergency departments should improve the diagnosis and treatment model of self-injured adolescent patients to ensure that they receive effective and high-quality medical resources.

The role of parents' and friends' support in preventing suicide attempts among French sexual minority adolescents

OBJECTIVES

French sexual minority adolescents are at higher risk for suicide attempts than their heterosexual peers. However, little is known about the role of parents' and friends' support among French lesbian, gay and bisexual (LGB) youth. This study aimed to research the role of their support in preventing suicide attempts among LGB adolescents in France.

MATERIALS AND METHODS

Data were drawn from a French cross-sectional study entitled "Portraits d'adolescents". Parental support was defined by satisfactory relations between participants and their parents. Friends' support was defined by satisfactory relations between participants and their friends. Chi-square and multiple logistic regression analyses were used to estimate and identify associated factors of suicide attempts in LGB as opposed to heterosexual youth.

RESULTS

Data from a sample of 14,265 French adolescents aged 13 to 20 were analyzed. Among them, 637 (4.47%) identified as LGB. Attempted suicide was independently associated with sexual orientation (30.7% vs 10.6%; OR = 2.59 [2.11-3.18]; p < 0.0001). Both parents' and friends' support appeared to be protective factors in suicide attempts among heterosexuals (adjusted ORs = 0.40 [0.35-0.46] and 0.61 [0.51-0.75], respectively), whereas in the LGB group, only parental support was significant (adjusted OR = 0.42 [0.27-0.65]), independently of other variables.

DISCUSSION

Prevention efforts might be carried out by identifying within-group differences among French adolescents with different sexual orientations. The supportive role of family members should be strengthened. Positive resources and salutary support systems may effectively prevent suicide attempts.

CONCLUSIONS

French LGB adolescents have a higher risk for suicide attempts than their heterosexual peers. Parental support was reconfirmed as a major protective factor against suicide attempts in sexual minority adolescents.

Suicidal ideation and its relationship with mental health reported by different informants among children aged 6-12

BACKGROUND

Suicidal ideation in children has received less attention than in adolescents. This study aimed to explore the self-reported prevalence of suicidal ideation among children aged 6-12 and to identify the relationship between self-reported suicidal ideation and children's mental health reported by different informants in Chinese setting.

METHOD

The study sample was 1479 children aged 6-12 from three elementary schools in Tianjin. Children completed the Dominic Interactive to report their mental health and suicidal ideation. Parents and teachers completed the Socio-Demographic Questionnaire and the Strengths and Difficulties Questionnaire (SDQ).

RESULTS

The prevalence of suicidal thoughts and death thoughts was 18.05 % and 16.90 %, respectively. Parent reported emotional symptoms, ADHD and externalized problems were associated with death thoughts, and ADHD was associated with suicidal thoughts. For teacher's reports, emotional symptoms, and impact were associated with death thoughts, and ADHD, peer problems, internalized problems, and internalized and externalized comorbidity were associated with suicidal thoughts. All of the children's self-reported mental health problems were associated with suicidal thoughts and death thoughts.

LIMITATIONS

Causality cannot be inferred in a cross-sectional study.

CONCLUSION

Suicidal ideation is not uncommon in Chinese children. The relationships between mental health problems and suicidal ideation varied in different informants. Suicide prevention in young children should be enhanced, and screening for suicidal ideation is recommended at the onset of different informants who reported specific mental health problems.

The Relationship Between Chronic Pain, Depression, Psychosocial Factors, and Suicidality in Adolescents

BACKGROUND

Chronic pain in youth is often associated with social conflict, depression, and suicidality. The interpersonal theory of suicide posits that there are psychosocial factors, such as peer victimization and lack of fear of pain, that may also influence suicidality.

OBJECTIVES

The objective of this study was to determine whether depressive symptoms, peer victimization, and lack of fear of pain predict suicidality in adolescents with chronic pain. It was hypothesized that higher levels of depressive symptoms and peer victimization, and lower levels of fear of pain, would predict a higher lifetime prevalence of suicidality.

METHODS

Participants consisted of 184 youth with primary chronic pain conditions (10 to 18 y, M = 14.27 y). Measures included diagnostic clinical interviews assessing suicidality and self-report questionnaires assessing depressive symptoms, peer victimization, and fear of pain.

RESULTS

Forty-two (22.8%) participants reported suicidality. Regression analyses demonstrated that the occurrence of suicidality was associated with higher rates of depressive symptoms (β = 1.03, P = 0.020, 95% CI: 1.01, 1.06) and peer victimization (β = 2.23, P < 0.05, 95% CI: 1.07, 4.63), though there was no association between lower fear of pain and suicidality.

DISCUSSION

These results suggest that depressive symptoms and peer victimization are significant predictors of suicidality in adolescents with chronic pain; however, lower fear of pain was not shown to be a significant predictor. Given these findings, depression and peer victimization should be further explored and considered in the design and implementation of prevention and early intervention strategies that target chronic pain and suicidality in youth.

Prevalence, predictors, and treatment of eating disorders in children: a national study

BACKGROUND

Although the prevalence rates of preadolescent eating disorders (EDs) are on the rise, considerably less is known about the correlates and treatment of EDs in this age group. Clarifying the epidemiology of EDs in preadolescent children is a necessary first step to understand the nature and scope of this problem in this age group.

METHODS

Analysis of data collected in the ABCD Study release 2.0.1. The ABCD cohort was a population-based sample that consisted of 11 721 children ages 9-10 years. Measures included reports of a lifetime and current mental disorders determined using a diagnostic interview for DSM-5 disorders, sociodemographic factors, and psychiatric treatment utilization.

RESULTS

The lifetime prevalence of EDs was 0.95%. Being Black, multiracial, having unmarried parents, and family economic insecurity were significant predictors for developing an ED. Among psychiatric conditions, the major depressive disorder was most robustly associated with EDs in both cross-sectional and temporal analyses. Only 47.40% of children who had a lifetime ED received some type of psychiatric treatment. EDs were not a significant predictor of psychiatric treatment utilization after accounting for sex, sexual orientation, parent marital status, economic insecurity, and all other psychiatric diagnoses.

CONCLUSIONS

Despite increasing prevalence rates of preadolescent EDs, the current findings suggest that the majority of children with these disorders remain untreated. Devoting increased attention and resources to reaching families of children with EDs with the least means for receiving care, and screening for EDs in children with depression, may be important steps for reducing this unmet need.

Psychosocial predictors of persistent suicidal ideation among Chinese adolescents: A longitudinal study

BACKGROUND

Suicide is the fourth leading cause of death among adolescents. Studies have shown that persistent suicidal ideation has a more important effect on suicidal behavior. The objective of this study was to identify predictors of persistent suicidal ideation.

METHODS

Data were collected from 4225 Chinese middle and high school students. These adolescents were assessed for suicidal ideation at baseline and the second year. We used multinomial logistic regression (n = 4171) for the predictive effect of these factors on persistent suicidal ideation. We controlled for gender, residence, clinical diagnosis, clinical diagnosis family, suicide planning, and suicide attempts.

RESULTS

Depressive symptoms are essential in predicting persistent suicidal ideation (OR = 14.0; p < 0.001). Persistent suicidal ideation was predicted by sleep disorders, such as poor sleep quality (OR = 2.3; p = 0.008), difficulty falling asleep (OR = 2.4; p = 0.005), frequently midnight awakening (OR = 1.9; p = 0.044), and frequent nightmares (OR = 2.1; p = 0.040). There was a significant association between concern with persistent ideation and parental-peer alienation (OR for father, 1.9[p = 0.024]; OR for mother, 3.1[p < 0.001]; OR for peer, 2.3[p = 0.003]).

LIMITATIONS

All measures are based on self-report rather than objective assessment or clinical diagnostic assessment.

CONCLUSIONS

Persistent suicidal ideation had a more important role in influencing suicide planning and attempt. Interventions targeting sleep disorders and attention to attachments in the home and school are particularly important in preventing persistent suicidal ideation in adolescents.

Contribution of Risk and Resilience Factors to Suicidality among Mental Health-Help-Seeking Adolescent Outpatients: A Cross-Sectional Study

BACKGROUND

Peer victimization is an established risk factor for youth suicidal thoughts and behavior (suicidality), yet most peer-victimized youth are not suicidal. More data are needed pertaining to factors that confer resilience to youth suicidality.

AIM

To identify resilience factors for youth suicidality in a sample of N = 104 (Mean age 13.5 years, 56% female) outpatient mental health help-seeking adolescents.

METHODS

Participants completed self-report questionnaires on their first outpatient visit, including the Ask Suicide-Screening Questions, a battery of risk (peer victimization and negative life events) and resilience (self-reliance, emotion regulation, close relationships and neighborhood) measures.

RESULTS

36.5% of participants screened positive for suicidality. Peer victimization was positively associated with suicidality (odds ratio [OR] = 3.84, 95% confidence interval [95% CI] 1.95-8.62, p < 0.001), while an overall multi-dimensional measure of resilience factors was inversely associated with suicidality (OR, 95% CI = 0.28, 0.11-0.59, p = 0.002). Nevertheless, high peer victimization was found to be associated with a greater chance of suicidality across all levels of resilience (marked by non-significant peer victimization by resilience interaction, p = 0.112).

CONCLUSIONS

This study provides evidence for the protective association of resilience factors and suicidality in a psychiatric outpatient population. The findings may suggest that interventions that enhance resilience factors may mitigate suicidality risk.

Establishment and validation of a nomogram for suicidality in Chinese secondary school students

BACKGROUND

Accurately identifying high-risk of suicide groups and conducting appropriate interventions are important to reduce the risk of suicide. In this study, a nomogram technique was used to develop a predictive model for the suicidality of secondary school students based on four aspects: individual characteristics; health risk behaviors; family factors; and school factors.

METHODS

A total of 9338 secondary school students were surveyed using the stratified cluster sampling method, and subjects were randomly divided into a training set (n = 6366) and a validation set (n = 2728). In the former, the results of the lasso regression and random forest were combined, from which 7 optimal predictors of suicidality were determined. These were used to construct a nomogram. This nomogram's discrimination, calibration, clinical applicability, and generalization were assessed using receiver operating characteristic curves (ROC), calibration curves, decision curve analysis (DCA), and internal validation.

RESULTS

Gender, depression symptoms, self-injury, running away from home, parents' relationship, relationship with father, and academic stress were found to be significant predictors of suicidality. The area under the curve (AUC) of the training set was 0.806, while that of the validation data was 0.792. The calibration curve of the nomogram was close to the diagonal, and the DCA showed the nomogram was clinically beneficial across a range of thresholds of 9-89 %.

LIMITATIONS

Causal inference is limited due to the cross-sectional design.

CONCLUSION

An effective tool was constructed for predicting suicidality among secondary school students, which should help school healthcare personnel assess this information about students and also identify high-risk groups.

Affiliation to a Social Group as a Preventive Factor in Suicidal Behaviors in Children and Adolescents during the COVID-19 Pandemic

Suicide is one of the most common causes of death in the population of children and adolescents. Available data show the continuous growth of this phenomenon and the ineffectiveness of prevention programs. Additionally, the COVID-19 pandemic significantly affected young people's mental health, including an increased risk of suicidal behaviors due to limited direct contact with the school and peer groups in favor of the home environment. Therefore, the aim of this narrative review was to consider the risk factors and protective factors for suicidal behavior in the under-18 population, with a particular focus on the importance of belonging to a social group and building identification with it as a phenomenon protecting against suicidal behavior. Additionally, in this review, we evaluate how the COVID-19 pandemic affected these relationships. The PubMed database was used in the search with the following keywords: suicide, suicide behaviors, child and adolescent suicide behaviors, group affiliation, family affiliation, ethnicity, religious affiliation, and the COVID-19 pandemic, with articles published between 2002 and 2022 analyzed. Research conducted to date indicates that both sustained and stable family and peer relationships, as well as a sense of identification and belonging, noticeably reduce the risk of suicidal behavior. Ethnic or cultural affiliation seems to have been particularly important during the isolation in the home environment caused by the COVID-19 pandemic. Additionally, it has been shown that while in lockdown, contact through social media with individuals' identification groups was associated with a reduced chance of emotional crises. Furthermore, regardless of cultural background, attachment to a particular group correlates with enhanced psychiatric state of children and adolescents. Thus, available data highlight the need for building and maintaining affiliations with suitable groups as a protective factor against suicidal behaviors.

COVID-19 Pandemic Has Changed the Psychiatric Profile of Adolescents Attempting Suicide: A Cross-Sectional Comparison

The COVID-19 pandemic is having a major impact on the mental health of adolescents, leading to suicidal behaviors. However, it remains to be clarified whether the COVID-19 pandemic has changed the psychiatric profile of adolescent suicide attempters.

METHODS

a retrospective observational analytical study was conducted to assess age, gender and clinical characteristics of adolescents attempting suicide during the year before and the year after the global lockdown.

RESULTS

ninety adolescents (12-17 y.o.) were recruited consecutively from February 2019 to March 2021 at the emergency ward for having attempted suicide. Fifty-two (57.8%) attended before the lockdown (pre-pandemic group) and thirty-eight (42.2%) the year after (pandemic group). There were significant differences in diagnostic categories between the periods (p = 0.003). Adjustment and conduct disorders were more frequent in the pre-pandemic group, while anxiety and depressive disorders were more prevalent during the pandemic. Although the severity of suicide attempts did not show significant differences between the two study periods (0.7), the generalized linear model showed that the suicide attempt severity was significantly associated with current diagnosis (p = 0.01).

CONCLUSIONS

the psychiatric profile of adolescents attempting suicide was different before and during the COVID-19 pandemic. During the pandemic, the proportion of adolescents with a prior psychiatric history was lower, and most of them were diagnosed with depressive and anxiety disorders. These diagnoses were also associated with a greater severity in the intentionality of suicide attempt, regardless of the study period.

Development and Validation of the Adolescent and Children in Risk of Abuse and Maltreatment Protective Factors Scale (ACRAM-PFS)

Background

Child maltreatment is a significant global problem concerning over 25% of children around the world. Traditionally, the assessment of children's welfare was characterized by the creation of instruments and models from the deficit-based theoretical framework.

Purpose

This study aims to develop an instrument to measure protective factors (the Adolescent and Children Risk of Abuse and Maltreatment Protective Factors Scale, ACRAM-PFS) and gather evidence on its psychometric properties. ACRAM-PFS is an 18-items scale for the assessment of protective factors of child maltreatment developed from the socioecological framework.

Method

Structural validity, reliability and convergent-related validity were studied for this measure in a sample of 616 children and adolescents, with age ranging from 0 to 18 years old (M = 12.14; SD = 5.22). Cases were informed by 286 child welfare workers. The sample was split in two subsamples, one to perform an Exploratory Factor Analysis (EFA) and the second to perform a Confirmatory Factor Analysis (CFA).

Results

The CFA corroborate the three-factor structure that includes the children and adolescents' resources, the family/caregiver's resources and the community resources (χ2 = 278.005, df = 132, p < .001, CFI = 0.955, SRMR = .084, RMSEA = .061, [90% CI: .051-.071]). Results of convergent-related validity indicated significant correlation with CTQ-SF and protective factors dimension of C-CAPS.

Discussion

The results support that ACRAM-PFS is a rigorous measure for assessing protective factors for child maltreatment. The scale can serve as a key tool for designing strengths-based intervention strategies tailored to the actual needs of children and adolescents. The present study provides the implications for the development of protective factor scales in the field of child welfare.

Interpersonal and Environmental Protective Factors and Their Associations With Children's Weight Status

Both external structure (ie, participating in extracurricular activities) and family factors (ie, parental emotional support) have separately been linked with children's physical health and well-being, however, their combined effects are less well known. The current study examined the longitudinal associations between participating in structured out-of-school activities and parent reports of warmth/emotional support with children's weight status (ie, zBMI) over time. Utilizing longitudinal data from the United States-based Early Childhood Longitudinal Study, Kindergarten Class of 2010 to 2011 (ECLS-K:2011), we employed a confirmatory factor analysis (CFA) and a latent variable cross-lagged path analysis to examine if emotional supportiveness and participation in structured activities predicted lower zBMI over the course of 1 year. The final sample included 18 135 participants. Mean age of the participants was 8.12 years (±0.38 years), and 51% of children were male. Mean zBMI was 0.54 (±1.12). Structure at baseline predicted increased zBMI in year 2 (β = .03, P = .02) but did not predict parent emotional supportiveness at year 2 (β = -.05, P = .09). Parent emotional supportiveness at baseline predicted greater zBMI at year 2 (β = .02, P = <.01) but did not predict structure at year 2 (β = .02, P = .39). zBMI at baseline did not predict structure (β = .02, P = .25) or parent emotional supportiveness at year 2 (β = -.01, P = .55). Our findings were inconsistent with our hypothesis with regard to directionality. Continued refinement about the role of internal structure (ie, family, and parenting practices) may inform public health prevention strategies to support the well-being of children and families.

Association between Asthma and Suicidality in 9-12-Year-Old Youths

PURPOSE

Suicidal ideation and attempts in youth are a growing health concern, and more data are needed regarding their biological underpinnings. Asthma is a common chronic inflammatory disorder in youth and has been associated with suicidal ideation and attempts in adolescent and adult populations, but data in younger children and early adolescents are lacking. We wished to study associations of asthma with childhood suicidality considering asthma's potential as a clinically relevant model for childhood chronic immune dysregulation.

METHODS

Using data from the Adolescent Brain Cognitive Development (ABCD) Study (n = 11,876, 47.8% female, mean age 9.9 years at baseline assessment and 12.0 years at two-year follow-up), we assessed associations between asthma and suicidal ideation and attempts through baseline to two-year follow-up.

RESULTS

Asthma history as defined by parent report (n = 2282, 19.2% of study population) was associated with suicide attempts (SA) (odds ratio (OR) = 1.44, p = 0.01), and this association remained significant even when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.46, p = 0.028). History of asthma attacks was associated with both suicidal ideation (SI) and SA when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.27, p = 0.042; OR = 1.83, p = 0.004, respectively). The association of asthma attack with SA remained significant when controlling for self-reported psychopathology (OR = 1.92, p = 0.004). The total number of asthma attacks was associated with both SI and SA (OR = 1.03, p = 0.043; OR = 1.06, p = 0.05, respectively).

CONCLUSIONS

Findings suggest an association between asthma and suicidality in early adolescence. Further research is needed to investigate mechanisms underlying this relationship.

Suicidal ideation and behaviour in Spanish adolescents during the COVID-19 pandemic: an exploratory study

The COVID-19 pandemic and its related containment measures, mainly physical distancing and isolation, are having detrimental consequences on the mental health of the juvenile infant population worldwide.

Associations Between Genetic Risk for Adult Suicide Attempt and Suicidal Behaviors in Young Children in the US

IMPORTANCE

Suicide rates have been increasing among youth in the US. While the heritability of suicide risk is well established, there is limited understanding of how genetic risk is associated with suicidal thoughts and behaviors in young children.

OBJECTIVE

To examine whether genetic susceptibility to suicide attempts (SAs) is associated with suicidal thoughts and behaviors in children.

DESIGN, SETTING, AND PARTICIPANTS

This case-control study examined data from the Adolescent Brain Cognitive Development (ABCD) study, a population-based longitudinal study of 11 878 US children enrolled at age 9 and 10 years from September 2016 to November 2018. Youth reports of suicidal ideation (SI) and SAs were obtained from the Kiddie Schedule for Affective Disorder and Schizophrenia at baseline and 2 subsequent years. After conservative quality control of genotype data, this analysis focused on 4344 unrelated individuals of European ancestry. Data analysis was conducted from November 2020 to February 2022.

MAIN OUTCOMES AND MEASURES

Children's lifetime experiences of SI and SAs were assessed each year from ages 9 to 10 years to ages 11 to 12 years. Polygenic risk scores (PRSs) for SAs were calculated for ABCD study participants based on the largest genome-wide association study of SA cases and controls of European ancestry (total sample n = 518 612).

RESULTS

Of 4344 children of European ancestry (2045 [47.08%] female; mean [SD] age, 9.93 [0.62] years), significant associations were found between children's SA PRSs and their lifetime SAs with the most robust association in the follow-up year 2 (odds ratio, 1.43 [95% CI, 1.18-1.75]; corrected P = 1.85 × 10-3; Nagelkerke pseudo R2 = 1.51%). These associations remained significant after accounting for children's sociodemographic backgrounds, psychopathology symptoms, parental histories of suicide and mental health, and PRSs for major depression and attention-deficit/hyperactivity disorder (likelihood ratio test P &lt; .05). Children's depressive mood and aggressive behavior were the most significant partial mediators of SA genetic risk on SAs (mediation analysis P &lt; 1 × 10-16). Children's behavioral problems, such as attention problems, rule-breaking behavior, and social problems, also partially mediated the association of SA PRSs with SAs (mediation analysis false discover rate &lt; 0.05).

CONCLUSIONS AND RELEVANCE

This study's findings indicate that there may be genetic factors associated with SA risk across the life span and suggest behaviors and conditions through which the risk could be mediated in childhood. Further research is warranted to examine whether incorporating genetic data could improve the identification of children at risk for suicide.

Peer victimization (bullying) on mental health, behavioral problems, cognition, and academic performance in preadolescent children in the ABCD Study

Objective

Peer victimization is a substantial early life stressor linked to psychiatric symptoms and poor academic performance. However, the sex-specific cognitive or behavioral outcomes of bullying have not been well-described in preadolescent children.

Methods

Using the baseline dataset of the Adolescent Brain Cognitive Development (ABCD) Study 2.0.1 data repository (N = 11,875), we evaluated associations between parent-reported bullying victimization, suicidality (suicidal ideation, intent, and/or behavior), and non-suicidal self-injury (NSSI), as well as internalizing and externalizing behavioral problems, cognition, and academic performance.

Results

Of the 11,015 9-10-year-old children included in the analyses (5,263 girls), 15.3% experienced bullying victimization, as reported by the primary caregiver. Of these, boys were more likely to be bullied than girls (odds ratio [OR], 1.2 [95% CI, 1.1-1.3]; p = 0.004). Children who were bullied were more likely to display NSSI or passive suicidality (OR, 2.4 [95% CI, 2.0-2.9]; p < 0.001) and active suicidality (OR, 3.4 [95% CI, 2.7-4.2]; p < 0.001). Bullied children also had lower cognitive scores, greater behavioral problems, and poorer grades (p < 0.001). Across all participants, boys had poorer grades and greater behavioral problems than girls; however, bullied boys had greater behavioral problems than girls in several areas (p < 0.001). Compared to their non-bullied peers, bullied children with greater non-suicidal self-injury or suicidality also had greater behavioral problems and poorer grades (p < 0.001).

Conclusion

These findings highlight the sex-specific effects of bullying, and the negative associations of bullying victimization with cognitive performance, behavioral problems, and academic performance. Future longitudinal studies will identify the natural history and neural correlates of these deficits during adolescence.

Psychosocial Factors and Sociodemographic Characteristics Associated with Suicidality Risk in Chilean Adolescents

Background: Suicidality in adolescents is a growing concern and is currently a public health issue in Chile and the world. Objective: To determine the association between the risk of suicidality with self-harm, sociodemographic parameters (that is, gender and type of school), psychosocial variables, and social and family support in Chilean adolescents. Methods: In a cross-sectional study, 829 (377, 45.5% girls) children/adolescents between 10 and 19 years of age participated. Suicidality, self-esteem, health-related quality of life (HRQoL), and social support perception were evaluated by standard, validated questionnaires. The presence of self-harm, dating violence, and family dysfunction was also evaluated through a self-report survey. Results: Suicidality risk was related to low self-esteem (OR = 9.73; 95%; CI = 6.62−14.28; p < 0.001), low HRQoL (OR = 5.0; 95%; CI = 3.51−7.13; p < 0.001), low social support (OR; 3.38, 95%; CI; 2.48−4.6; p < 0.001), and self-harm (OR = 8.03; 95%; CI = 5.69−11.33; p < 0.001). In family terms, suicidality risk was associated with exposure to physical (OR = 2.47, 95%CI; 1.69−3.6; p < 0.001) and psychological (OR = 1.78, 95; 1.33−2.39; p < 0.001) aggression between parents, and with considering their family dysfunctional (OR = 2.41 95%; CI = 1.69−3.41; p < 0.001). Finally, suicidality was associated with feeling mistreated by a boyfriend/girlfriend (OR = 2.18; 95% CI = 1.19−3.98; p = 0.011). Conclusion: Suicidality was associated with self-harm, low social, psychological and family well-being, and/or feeling mistreated by a boyfriend/girlfriend.

Genetic Association of Attention-Deficit/Hyperactivity Disorder and Major Depression With Suicidal Ideation and Attempts in Children: The Adolescent Brain Cognitive Development Study

BACKGROUND

Suicide is among the leading causes of death in children and adolescents. There are well-known risk factors of suicide, including childhood abuse, family conflicts, social adversity, and psychopathology. While suicide risk is also known to be heritable, few studies have investigated genetic risk in younger individuals.

METHODS

Using polygenic risk score analysis, we examined whether genetic susceptibility to major psychiatric disorders is associated with suicidal behaviors among 11,878 children enrolled in the ABCD (Adolescent Brain Cognitive Development) Study. Suicidal ideation and suicide attempt data were assessed using the youth report of the Kiddie Schedule for Affective Disorders and Schizophrenia for DSM-5. After performing robust quality control of genotype data, unrelated individuals of European descent were included in analyses (n = 4344).

RESULTS

Among 8 psychiatric disorders we examined, depression polygenic risk scores were associated with lifetime suicide attempts both in the baseline (odds ratio = 1.55, 95% CI = 1.10-2.18, p = 1.27 × 10-2) and in the follow-up year (odds ratio = 1.38, 95% CI = 1.08-1.77, p = 1.05 × 10-2), after adjusting for children's age, sex, socioeconomic backgrounds, family history of suicide, and psychopathology. In contrast, attention-deficit/hyperactivity disorder polygenic risk scores were associated with lifetime suicidal ideation (odds ratio = 1.15, 95% CI = 1.05-1.26, p = 3.71 × 10-3), suggesting a distinct contribution of the genetic risk underlying attention-deficit/hyperactivity disorder and depression on suicidal behaviors of children.

CONCLUSIONS

The largest genetic sample of suicide risk data in U.S. children suggests a significant genetic basis of suicide risk related to attention-deficit/hyperactivity disorder and depression. Further research is warranted to examine whether incorporation of genomic risk may facilitate more targeted screening and intervention efforts.

Misuse of Prescription Opioids and Suicidal Behaviors Among Black Adolescents: Findings from the 2017 and 2019 Youth Risk Behavior Survey

PURPOSE

Although some studies have examined the association between prescription opioid misuse and mental health outcomes, few have investigated the effects of prescription opioid misuse on suicidal behaviors among Black adolescents. The objective of this study was to investigate the cross-sectional association between prescription opioid misuse and suicidal ideation, suicide plan, and suicide attempt among Black adolescents.

METHODS

Data for this study came from the 2017 and 2019 Youth Risk Behavior Survey. An analytic sample of 4798 Black adolescents aged 14-18 years (51.2% female) was analyzed using binary logistic regression. The outcome variables investigated were suicidal ideation, suicide plan, and suicide attempt, and the main explanatory variable was prescription opioid misuse.

RESULTS

Of the 4798 Black adolescents, 15% reported ever misusing prescription opioids; 16.2% experienced suicidal ideation; 14% made a suicide plan; and 11.3% attempted suicide during the past 12 months. In the multivariate logistic regression models, Black adolescents who misused prescription opioids had 1.39 times higher odds of making a suicide plan and 1.65 times higher odds of making a suicide attempt during the past 12 months when compared to their counterparts who did not misuse prescription opioids. Other significant factors associated with suicidal behaviors include female sex, school bullying, cyberbullying, depressive symptoms, and illicit drug use. In addition, physical activity had a protective effect on suicide attempt.

CONCLUSION

The findings of the present study demonstrate the effects of prescription opioid misuse and its association with suicidal behaviors among Black adolescents.

Design, development, and evaluation of a surveillance system for suicidal behaviors in Iran

BACKGROUND

Suicide is a serious cause of morbidity and mortality in Iran and worldwide. Although several organizations gather information on suicide and suicide attempts, there is substantial misperception regarding the description of the phenomenon. This study proposes the minimum data set (MDS) for suicidal behaviors surveillance.

METHODS

A literature review was first conducted to achieve a thorough overview of suicide-related items and map the existing evidence supporting the development of the MDS. The data items included in the literature review were then analyzed using a two-round Delphi technique with content validation by an expert panel. The suicidal behaviors surveillance system was then established based on the confirmed MDS, and ultimately, its performance was assessed by involving the end-users.

RESULTS

The panel of experts consisted of 50 experts who participated in the Delphi phase and validity content review. Of these, 46% were men, and their mean age and average work experience were (36.4, SD ± 6.4) and (12.32, SD ± 5.2) years, respectively. The final MDS platform of our study contained 108 items classified into eight main categories. A web-based system with a modular and layered architecture was developed based on the derived MDS.

CONCLUSION

The developed system provides a framework for recording suicidal behaviors' data. The integration of multiple suicide-related information systems at the regional and national levels makes it possible to assess the long-term outcomes and evolutions of suicide prevention interventions.

Predictors of Suicide Re-Attempt in a Spanish Adolescent Population after 12 Months' Follow-Up

Background: This study aims to identify the main predictive factors that allow for the recognition of adolescents with a higher risk of re-attempting suicide. Method: A longitudinal 12-month follow-up design was carried out in a sample of 533 Spanish adolescents between 12 and 17 years old. The data collection period comprised September 2013 to November 2016, including a one-year follow-up after hospital discharge. Results: A statistically significant regression model was obtained to predict suicide re-attempt at 12-months’ follow-up (χ2 = 34.843; p < 0.001; Nagelkerke R2 = 0.105), including personal history of self-injury (OR = 2.721, p < 0.001, 95% CI [1.706, 4.340]) and age (OR = 0.541, p = 0.009, 95% CI [0.340, 0.860]), correctly classifying 82.6% of the sample. Our results show that having a personal history of self-injury and being younger than 14 years old were predictors of suicide re-attempt during the first year after an adolescent’s first admission to emergency services. Conclusions: Considering these factors could contribute to the design of more tailored and effective interventions to prevent suicidal behavior in adolescents at high risk of re-attempting suicide.

Correlates and predictors of the severity of suicidal ideation in adolescence: an examination of brain connectomics and psychosocial characteristics

BACKGROUND

Suicidal ideation (SI) typically emerges during adolescence but is challenging to predict. Given the potentially lethal consequences of SI, it is important to identify neurobiological and psychosocial variables explaining the severity of SI in adolescents.

METHODS

In 106 participants (59 female) recruited from the community, we assessed psychosocial characteristics and obtained resting-state fMRI data in early adolescence (baseline: aged 9-13 years). Across 250 brain regions, we assessed local graph theory-based properties of interconnectedness: local efficiency, eigenvector centrality, nodal degree, within-module z-score, and participation coefficient. Four years later (follow-up: ages 13-19 years), participants self-reported their SI severity. We used least absolute shrinkage and selection operator (LASSO) regressions to identify a linear combination of psychosocial and brain-based variables that best explain the severity of SI symptoms at follow-up. Nested-cross-validation yielded model performance statistics for all LASSO models.

RESULTS

A combination of psychosocial and brain-based variables explained subsequent severity of SI (R² = .55); the strongest was internalizing and externalizing symptom severity at follow-up. Follow-up LASSO regressions of psychosocial-only and brain-based-only variables indicated that psychosocial-only variables explained 55% of the variance in SI severity; in contrast, brain-based-only variables performed worse than the null model.

CONCLUSIONS

A linear combination of baseline and follow-up psychosocial variables best explained the severity of SI. Follow-up analyses indicated that graph theory resting-state metrics did not increase the prediction of the severity of SI in adolescents. Attending to internalizing and externalizing symptoms is important in early adolescence; resting-state connectivity properties other than local graph theory metrics might yield a stronger prediction of the severity of SI.

Association of Cyberbullying Experiences and Perpetration With Suicidality in Early Adolescence

IMPORTANCE

Adolescent suicidality (ie, suicidal ideation or attempts) is a major public health concern. Cyberbullying experiences and perpetration have become increasingly prevalent and are associated with mental health burden, but their roles as independent suicidality risk factors remain unclear. Data are needed to clarify their contribution to teen suicidality to inform suicide prevention efforts.

OBJECTIVE

To examine whether cyberbullying experiences and perpetration are distinct stressors divergent from other forms of peer aggression experiences in their association with suicidality in early adolescence.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional analysis used data collected between July 2018 and January 2021 from the Adolescent Brain Cognitive Development (ABCD) study, a large, diverse sample of US children aged 10 to 13 years.

EXPOSURES

Youth reports of cyberbullying experiences or perpetration.

MAIN OUTCOMES AND MEASURES

The main outcome was youth-reported suicidality (past or present, as reported in the ABCD 2-year follow-up assessment). Covariates included demographics, established environmental risk and protective factors for youth suicidality, psychopathology, and experiences or perpetration of offline peer aggression.

RESULTS

A total of 10 414 ABCD participants were included in this study. Participants had a mean (SD) age of 12.0 (0.7) years and 4962 (47.6%) were female; 796 (7.6%) endorsed suicidality. A total of 930 (8.9%) reported experiencing cyberbullying and 96 (0.9%) reported perpetrating cyberbullying. Of the perpetrators, 66 (69.0%) also endorsed experiencing cyberbullying. Controlling for demographics, experiencing cyberbullying was associated with suicidality (odds ratio [OR], 4.2 [95% CI, 3.5-5.1]; P < .001), whereas perpetrating cyberbullying was not (OR, 1.3 [95% CI, 0.8-2.3]; P = .30). Experiencing cyberbullying remained associated with suicidality when accounting for negative life events, family conflict, parental monitoring, school environment, and racial and ethnic discrimination (OR, 2.5 [95% CI, 2.0-3.0]; P < .001) and when further covarying for internalizing and externalizing psychopathology (OR, 1.8 [95% CI, 1.4-2.4]; P < .001). Both being a target and being a perpetrator of offline peer aggression were associated with suicidality (OR, 1.5 [95% CI, 1.1-2.0] for both), controlling for all covariates described earlier. Cyberbullying experiences remained associated with suicidality (OR, 1.7 [95% CI, 1.3-2.2]; P < .001, controlling for all covariates) when included with offline peer aggression experiences and perpetration.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, experiencing-but not perpetrating-cyberbullying was associated with suicidality in early adolescence. This association was significant over and above other suicidality risk factors, including offline peer aggression experiences or perpetration. These findings can inform adolescent suicide prevention strategies, and they suggest that clinicians and educational staff working with this population should routinely evaluate for adolescents' experience with cyberbullying.

Risk and Protective Factors Associated with Suicidal Thoughts and Behaviors Among Maryland Middle School Students

The aim of this study was to identify independent risk and protective factors associated with self-reported suicidal thoughts and behaviors (STB) among young adolescents by examining self-report data on mental health, substance abuse, violence involvement, social and economic challenges and supports, physical health and demographics in relation to STB. Data from nearly 27,000 students who completed the 2018-19 Maryland Middle School Youth Risk Behavior Survey/Youth Tobacco Survey (YRBS/YTS) were used to identify independent risk and protective factors associated with STB among middle school students (grades 6–8; ages 11-14). Twenty-three percent of students reported lifetime suicidal ideation and nine percent reported lifetime attempt(s). Independent risk factors associated with STB include depression, substance abuse or misuse, violence involvement, bullying victimization at school or electronically, sexual activity, and sleep deprivation. Protective factors include having an adult outside of school to confide in and feeling that teachers care and provide encouragement. Interactive effects by gender and/or race/ethnicity were observed for some factors in relation to STB. These results suggest that evidence-based programs and policies at the universal and selective/indicated levels in school settings are needed and should be introduced earlier on to address the widespread prevalence of STB in young adolescents. Program planners should take into consideration social, cultural and language needs when implementing and developing intervention strategies.

Finding the Link between Cyberbullying and Suicidal Behaviour among Adolescents in Peninsular Malaysia

Social media engagement has contributed to the rise of cyberbullying, which has recently triggered tragic suicides among adolescents. The objective of this cross-sectional study is to determine the prevalence of cyberbullying, suicidal behaviour, and their association among adolescents in Peninsular Malaysia. The study was conducted among 1290 secondary school adolescents aged between 13 and 17 years old in Peninsular Malaysia using a self-administered and anonymous online questionnaire. Our findings reveal that the prevalence of cyberbullying victimization and perpetrator is 13.7% and 3.8%, respectively. The prevalence of suicidal behaviour among adolescents is 17.1%, in which 11.9% had suicidal thoughts, 10.2% had a suicide plan, and 8.4% had made a suicide attempt. Multiple logistic regression shows that adolescents experiencing cyberbullying victimization is a significant risk factor (p < 0.001) for suicidal behaviour after adjusting for other confounders. An alarming number of adolescents in Peninsular Malaysia found to be involved in cyberbullying and its significant association with suicidal behaviour warrant the need to strengthen current interventions. Since the study was conducted during the COVID-19 pandemic, our findings make an important contribution in reporting current trends in cyberbullying and suicide among adolescents, especially when they are becoming ever-more present in cyberspaces.

Nonsuicidal self-injury behaviour in a city of China and its association with family environment, media use and psychopathology

INTRODUCTION

It is not clear whether there are differences in the risk factors for nonsuicidal self-injury (NSSI) between children and early adolescents. Clarifying this question is crucial for identifying actionable prevention strategies for NSSI in these two age groups.

METHOD

The study, comprising 8611 children and early adolescents (4409 (51.2%) children, 4202 (48.8%) early adolescents), was based on the baseline data of the Chengdu Positive Child Development (CPCD) in China. NSSI behaviours, emotional and behavioural problems and family environment were assessed and obtained via self-reports and parent reports.

RESULTS

Overall, 2520 (29.26%) participants reported having ever engaged in NSSI. There was a higher lifetime NSSI rate in males than in females during childhood, contrasting with higher NSSI rates in females than in males during early adolescence. Furthermore, NSSI shared similar risk factors, including major family conflict and poor relationships with caregivers, in both age groups. Specifically, in children, the risk of NSSI increased along with thought and attention problems (OR, 95% CI: 1.194, 1.106-1.288 and 1.114, 1.028-1.207, respectively), whereas in early adolescents, it increased with anxiety and depressive problems (OR, 95% CI: 1.259, 1.116-1.422).

CONCLUSIONS

The findings suggested the need for difference in preventive strategies for NSSI in the two age groups. It may be more efficacious to screen for NSSI in children with thought and attention problems and in early adolescents with anxiety and depressive problems.
