Self-harm in primary school-aged children: Prospective cohort study

Cyberbullying Perpetration and Victimization as Risk Factors for Self-Harm: Results From a Longitudinal Cohort Study of 13-14-Year-Olds in England

PURPOSE

Cyberbullying is a crucial issue that affects adolescent mental health, with evidence to suggest that adolescents who are victims of cyberbullying are at higher risk for self-harm. However, longitudinal evidence is lacking, meaning the direction of effects cannot be established. This study investigated longitudinal associations between levels of cyberbullying involvement (bully, victim, or both), frequency, and self-harm a year later in an adolescent sample.

METHODS

Data were collected from Year 9 students (13-14-year-olds; N = 1,195) enrolled in 19 schools in Southwest England using an online questionnaire with a 1-year follow-up period (October 2019-October 2020). Multivariable logistic regression analysis was conducted to test for associations between different levels of cyberbullying involvement at baseline and the likelihood of self-harm a year later, adjusting for key covariates. A secondary regression analysis also explored the associations between the frequency of cyberbullying involvement at baseline and subsequent self-harm.

RESULTS

Compared to those with no cyberbullying involvement, individuals who were both victims and perpetrators (adjusted odds ratio = 2.94, 95% confidence interval: 1.99-4.34) as well as victims only (adjusted odds ratio = 2.81, 95% confidence interval: 1.95-4.04) showed an increased risk of subsequent self-harm. In terms of frequency, associations were found between frequent and occasional cyberbullying and self-harm for both victims and perpetrators; however, associations for the perpetrator group attenuated to the null following adjustment for covariates.

DISCUSSION

Our findings highlight cyberbullying in early adolescence as a risk factor for subsequent self-harm. Cyberbullying prevention should be a priority for school mental health interventions, with consideration that most perpetrators of cyberbullying may also be victims.

Risk Factors Associated With Bullying in Context of a Territory Exposed to Armed Conflict: A Cross-sectional Study

School violence and bullying are current and problematic events during adolescence. They are likely to have a marked presence in places highly exposed to armed conflict and violent environments, representing a double public health problem. The study aims to estimate the prevalence of different types of school violence perpetrated and experienced by school adolescents in a community with a history of exposure to armed conflict. Two thousand one hundred eighty-five school adolescents from a municipality in Colombia (males = 54.1%, 14-16 years = 38.6%) participated in the study. Nine educational institutions were included. A systematic random sampling was designed, with a proportional allocation of 35% within each school year from sixth to eleventh grade. The School Coexistence and Circumstances Affecting it-ECECA survey was applied. The prevalence and risks of bully and bullying were estimated. RRa were calculated with the 95% confidence interval adjusted for the other confounding variables. Analyses were constructed from generalized linear models, under the Poisson family and a logarithmic link function. We found a 9.3% of bullying victimization and a 3.5% prevalence of bully. A higher risk of bully was found among males, persons between 10 and 14 years of age, residents of rural or urban dispersed areas, residents of violent neighborhoods, alcohol consumers at school, and victims of aggression in childhood (RRa > 1.0, p-values <.05). The risk of victimization of bullying was higher in students younger than 15 years old, as residents of urban areas, having a history of childhood aggression, suffering abuse by a close person, and as alcohol users at school. This study provides evidence of risk factors for aggression and bullying that have implications for possible prevention measures in multiple social domains, including the individual, the family, and the school environment.

Self-harm in 5-to-24 year olds: Retrospective examination of hospital presentations to emergency departments in New South Wales, Australia, 2012 to 2020

There is some evidence that self-harm presentations in children and young people have increased over the past decade, yet there are few up-to-date studies examining these trends. This study aims to describe trends in the rates and severity of emergency department self-harm presentations for youth aged 5-24 years in New South Wales, Australia between 1 January 2012 and 31 December 2020. We analysed self-harm hospital presentations using join point analysis to compare quarterly growth in rates and urgency of presentation since 2012 by age group and sex. Binomial logistic modelling was used to identify risks for re-presentation for self-harm, including age group, sex, country of birth, mode of arrival, inpatient status, triage category, rurality, and socio-economic disadvantage. In total, 83,111 self-harm presentations for 51,181 persons were analysed. Overall rates of self-harm among those aged 5-24 years increased by 2.4% (p < .001) per quarter in females and 1.6% (p < .001) per quarter in males, with statistically significant average quarterly increases observed across all age groups. Overall and age-specific self-harm triage urgency rates increased statistically significantly for potentially serious, and potentially- and immediately life-threatening categories. A higher likelihood of re-presentation to any emergency department for self-harm was associated with younger age, female, residing in a regional area, arriving by ambulance, admitted as an in-patient, and a more severe index self-harm presentation. Hospital self-harm presentations have been growing steadily over the past decade, with the greatest growth in the youngest people. Understanding the reasons for these sustained upward trends is a priority for suicide prevention.

The longitudinal course of childhood bullying victimization and associations with self-injurious thoughts and behaviors in children and young people: A systematic review of the literature

INTRODUCTION

Bullying victimization has consistently been highlighted as a risk factor for self-injurious thoughts and behaviors (SITBs) in young people. This systematic review of prospective, community-based studies explored associations between bullying victimization (traditional/face-to-face and cyber) across the full spectrum of self-harm and suicidality, in children and young people aged up to (and including) 25 years. Importantly, associations by sex/gender were explored.

METHODS

MEDLINE, Embase, PsycINFO, CINAHL and Scopus were searched for articles meeting the inclusion criteria. Articles were screened by title, abstract and full text. Quality appraisal was performed using the Newcastle-Ottawa Scale for cohort studies. Data were synthesized narratively. The protocol is registered on PROSPERO (CRD42021261916) and followed PRISMA 2020 guidelines.

RESULTS

A total of 35 papers were included, across 17 countries. Results were presented by bullying type: traditional/face-to-face (n = 25), cyber (n = 7) and/or an aggregate of both types (n = 7). Outcomes included suicidal ideation (n = 17), self-harm (n = 10), suicide attempt (n = 4), NSSI (n = 4), other (n = 7). Studies measured outcomes in under 18s (n = 24), 18-25-year-olds (n = 8) and both under 18s and 18-25-year-olds (n = 3). Studies exploring the role of sex/gender (20%) found some interesting nuances.

CONCLUSIONS

Some weak to strong associations between bullying and SITBs were found yet conclusions are tentative due to study heterogeneity (e.g., methods used, conceptualizations and operationalisations of exposures/outcomes). Future research should address methodological issues raised in this review, and further explore gender differences in bullying, including by bullying sub-types (e.g., overt or relational) and victim status (e.g., victim or bully-victim).

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

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

Risk and protective factors for self-harm and suicide in children and adolescents: a systematic review and meta-analysis protocol

INTRODUCTION

Self-harm and suicide are major public health concerns among children and adolescents. Many risk and protective factors for suicide and self-harm have been identified and reported in the literature. However, the capacity of these identified risk and protective factors to guide assessment and management is limited due to their great number. This protocol describes an ongoing systematic review and meta-analysis which aims to examine longitudinal studies of risk factors for self-harm and suicide in children and adolescents, to provide a comparison of the strengths of association of the various risk factors for self-harm and suicide and to shed light on those that require further investigation.

METHODS AND ANALYSIS

We perform a systematic search of the literature using the databases EMBASE, PsycINFO, Medline, CINAHL and HMIC from inception up to 28 October 2020, and the search will be updated before the systematic review publication. Additionally, we will contact experts in the field, including principal investigators whose peer-reviewed publications are included in our systematic review as well as investigators from our extensive research network, and we will search the reference lists of relevant reviews to retrieve any articles that were not identified in our search. We will extract relevant data and present a narrative synthesis and combine the results in meta-analyses where there are sufficient data. We will assess the risk of bias for each study using the Newcastle-Ottawa Scale and present a summary of the quantity and the quality of the evidence for each risk or protective factor.

ETHICS AND DISSEMINATION

Ethical approval will not be sought as this is a systematic review of the literature. Results will be published in mental health journals and presented at conferences focused on suicide prevention.

Multiple imputation approaches for handling incomplete three-level data with time-varying cluster-memberships

Three-level data arising from repeated measures on individuals clustered within higher-level units are common in medical research. A complexity arises when individuals change clusters over time, resulting in a cross-classified data structure. Missing values in these studies are commonly handled via multiple imputation (MI). If the three-level, cross-classified structure is modeled in the analysis, it also needs to be accommodated in the imputation model to ensure valid results. While incomplete three-level data can be handled using various approaches within MI, the performance of these in the cross-classified data setting remains unclear. We conducted simulations under a range of scenarios to compare these approaches in the context of an acute-effects cross-classified random effects substantive model, which models the time-varying cluster membership via simple additive random effects. The simulation study was based on a case study in a longitudinal cohort of students clustered within schools. We evaluated methods that ignore the time-varying cluster memberships by taking the first or most common cluster for each individual; pragmatic extensions of single- and two-level MI approaches within the joint modeling (JM) and the fully conditional specification (FCS) frameworks, using dummy indicators (DI) and/or imputing repeated measures in wide format to account for the cross-classified structure; and a three-level FCS MI approach developed specifically for cross-classified data. Results indicated that the FCS implementations performed well in terms of bias and precision while JM approaches performed poorly. Under both frameworks approaches using the DI extension should be used with caution in the presence of sparse data.

Returning to the emergency department: a retrospective analysis of mental health re-presentations among young people in New South Wales, Australia

OBJECTIVES

This study aimed to describe mental health emergency department (ED) presentations among young people aged 8-26 years in New South Wales, Australia, and to identify key characteristics associated with higher risk of ED mental health re-presentation.

DESIGN, SETTING AND PARTICIPANTS

Retrospective analysis of linked ED data records for mental health presentations between 1 January 2015 and 30 June 2018.

MAIN OUTCOME MEASURES

The main outcome was the total number of mental health ED re-presentations within 1 year, following initial presentation. Count regression models were fitted to estimate factors associated with higher likelihood of re-presentations.

RESULTS

Forty thousand two hundred and ninety patients were included in the analyses, and 9713 (~25%) re-presented during the following year; 1831 (20%) presented at least three times. On average, patients re-presented 0.61 times per 365 person-days, with average time until first re-presentation of ~92 days but greatest risk of re-presentation within first 30-60 days. Young people with self-harm or suicidal diagnoses at initial presentation were more likely to re-present. Re-presentations were highest among young people <15 years (IRR 1.18 vs ≥20 years old), female (IRR=1.13 vs male), young people residing outside of major cities (IRR 1.08 vs major cities) and Aboriginal and Torres Strait Islander young people (IRR 1.27 vs non-Indigenous).

CONCLUSIONS

ED mental health re-presentation is high among young people. We demonstrate factors associated with re-presentation that EDs could target for timely, high-quality care that is youth friendly and culturally safe, with appropriate referral pathways into community-based primary and mental healthcare services.

Peripheral and neural correlates of self-harm in children and adolescents: a scoping review

BACKGROUND

Self-harm in children and adolescents is difficult to treat. Peripheral and neural correlates of self-harm could lead to biomarkers to guide precision care. We therefore conducted a scoping review of research on peripheral and neural correlates of self-harm in this age group.

METHODS

PubMed and Embase databases were searched from January 1980-May 2020, seeking English language peer-reviewed studies about peripheral and neural correlates of self-harm, defined as completed suicide, suicide attempts, suicidal ideation, or non-suicidal self-injury (NSSI) in subjects, birth to 19 years of age. Studies were excluded if only investigating self-harm in persons with intellectual or developmental disability syndromes. A blinded multi-stage assessment process by pairs of co-authors selected final studies for review. Risk of bias estimates were done on final studies.

RESULTS

We screened 5537 unduplicated abstracts, leading to the identification of 79 eligible studies in 76 papers. Of these, 48 investigated peripheral correlates and 31 examined neural correlates. Suicidality was the focus in 2/3 of the studies, with NSSI and any type of self-harm (subjects recruited with suicidality, NSSI, or both) investigated in the remaining studies. All studies used observational designs (primarily case-control), most used convenience samples of adolescent patients which were predominately female and half of which were recruited based on a disorder. Over a quarter of the specific correlates were investigated with only one study. Inter-study agreement on findings from specific correlates with more than one study was often low. Estimates of Good for risk of bias were assigned to 37% of the studies and the majority were rated as Fair.

CONCLUSIONS

Research on peripheral and neural correlates of self-harm is not sufficiently mature to identify potential biomarkers. Conflicting findings were reported for many of the correlates studied. Methodological problems may have produced biased findings and results are mainly generalizable to patients and girls. We provide recommendations to improve future peripheral and neural correlate research in children and adolescents, ages 3-19 years, with self-harm.

[Non-suicidal self-injurious Behaviour: Insights into a littleknown Patient Population in Plastic Surgery]

BACKGROUND

Despite its high prevalence in adolescents and young adults, non-suicidal self-injury (NSSI) is poorly known and understood in areas other than psychiatry. Due to this lack of knowledge, affected patients often face a lack of understanding as well as rejection and discrimination when seeking help from medical professionals. This not only hampers a lasting improvement of NSSI and the development of a trustful physician-patient relationship but may also lead to traumatisation of affected patients. Based on our patients' data, this article aims to inform interested plastic surgeons about NSSI and thus to support the treatment of affected patients.

PATIENTS AND METHODS

600 patients with scars from NSSI presenting to our outpatient clinic for the first time during the past five years were enrolled in this study. Extensive data collected during the first contact was analysed and compared with the current literature.

RESULTS

95 % of the patients were female; 5 % were male. On average, patients presented 8.4 years after the last NSSI event and with a mean age of 26 years. NSSI scars were most often located on the left forearm (48 %), followed by both forearms (40 %), the left upper arm (20 %), both upper arms (15 %) and both thighs (14 %). In 57 % of patients, scars were only present on one side. A mean of 380 cm2 of the body surface was affected by NSSI scars. 47 % of patients reported having at least one additional diagnosis, with thyroid dysfunction and depression being the most common. 21 % of patients had ongoing psychiatric or psychological therapy at the time of their first consultation in our clinic.

CONCLUSION

Our data provides first insight into a large population of NSSI patients seeking treatment options for their NSSI-associated scars in a plastic surgery outpatient clinic. Most patients were female with scars located on their forearms. A mean of more than 8 years had passed between their last NSSI and their first presentation to our clinic. Our findings offer a data-based approach to a group of patients with a disease pattern that is largely misunderstood in surgical disciplines and needs more attention, especially in the light of its high prevalence and life-long consequences.

Prevalence, Response and Management of Self-harm in School Children Under 13 Years of Age: A Qualitative Study

Research suggests that the incidents of self-harm among young people are increasing and age of onset of self-harm is decreasing. There is limited understanding of how widespread the problem of self-harm among younger school students is, and how schools respond to these incidents. This study used an in-depth qualitative approach to understand self-harm in children under 13, and how elementary schools respond including typical actions, support for the child and parental involvement. School psychologists in New South Wales, Australia (n = 17; 78% females), completed in-depth interviews detailing types of self-harm, prevalence and frequency, and how these incidents were managed, including student intervention approaches and participation of parents. Thematic analysis of interviews was conducted. Psychologists estimated the prevalence of self-harm in their schools was 6.5% and was increasing, with an average age of onset of 10.8 years. Self-harm was most often understood as a coping mechanism associated with anxiety, stress and being bullied. Six themes emerged from the interviews. School psychologists reported that self-harm occurs less frequently in primary school children than high school children, but noted these behaviours still require early intervention. Participants felt they were limited in the support they can provide students who self-harm, and wanted more training for all school staff and parents in identifying and responding to student self-harm. School psychologists are important in identification and management of self-harm, and they report they need further support in helping children who are engaging in self-harm behaviours. Upskilling teachers and parents may assist in reducing rates of self-harm among children.

Self-harm in children 12 years and younger: characteristics and outcomes based on the Multicentre Study of Self-harm in England

BACKGROUND

Very little is known about self-harm in children. We describe the characteristics and outcomes of children under 13 years who presented following self-harm to five hospitals in England.

METHODS

We included children under 13 years who presented after self-harm to hospitals in the Multicentre Study of Self-harm in England. Information on patients' characteristics and method of self-harm was available through monitoring of self-harm in the hospitals. Area level of socioeconomic deprivation was based on the English Index of Multiple Deprivation (IMD).

RESULTS

387 children aged 5-12 years presented to the study hospitals in 2000-2016, 39% of whom were 5-11 years. Boys outnumbered girls 2:1 at 5-10 years. The numbers of boys and girls were similar at age 11, while at 12 years there were 3.8 girls to every boy. The proportion of study children living in neighbourhoods ranked most deprived (43.4%) was twice the national average. 61.5% of children self-poisoned, 50.6% of them by ingesting analgesics. Of children who self-injured, 45.0% self-cut/stabbed, while 28.9% used hanging/asphyxiation. 32% of the children had a repeat hospital presentation for self-harm, 13.5% re-presented within a year.

CONCLUSIONS

Gender patterns of self-harm until age 11 years are different to those of adolescents, with a male preponderance, especially in 5-10 years, and hanging/suffocation being more common. The frequent use of self-poisoning in this age group highlights the need for public health messages to encourage safer household storage of medicines. Self-harm in children is strongly associated with socioeconomic deprivation; understanding the mechanisms involved could be important in effective prevention.
