Suicide and self-harm

Prevalence and correlates of non-suicidal self-injury among patients with bipolar disorder: A multicenter study across China

BACKGROUND

Non-suicidal self-injury (NSSI) is increasingly prevalent among patients with bipolar disorder (BD), raising concerns in psychology and mental health. Investigating the incidence and factors associated with NSSI is crucial for developing prevention and intervention strategies.

METHODS

NSSI behaviors were identified using the Ottawa Self-injury Inventory. The Clinically Useful Depression Outcome Scale supplemented with questions for the DSM-5 specifier of mixed features (CUDOS-M) and the Mini International Neuropsychiatric Interview (Hypo-)Manic Episode with Mixed Features-DSM-5 Module (MINI-M) were used to evaluate clinical symptoms. Non-parametric tests, chi-square tests, point-biserial correlation and logistic regression analyses were employed for the purposes of data analysis.

RESULTS

The enrolled sample comprised 1044 patients with BD from 20 research centers across China. Out of 1044 individuals, 446 exhibited NSSI behaviors, with 101 of them being adolescents, leading to a prevalence of 78.3 % among adolescent patients. The most common methods for females and males were "cutting" (41.2 %) and "hitting" (34.7 %), respectively. By binary logistic regression analysis, young age, female, bipolar type II disorder, with suicidal ideation and mixed states, depressive symptoms and without family history of mental disorder were correlates of NSSI in patients with BD (P < 0.05).

LIMITATIONS

As a cross-sectional study, causality between NSSI behaviors and associated factors cannot be established. Reporting and recall biases may occur due to self-rating scales and retrospective reports.

CONCLUSION

Our study indicates a concerning prevalence of NSSI, particularly among young patients with BD in China. Future research should focus on understanding NSSI behaviors in this population and developing effective interventions.

Prediction of Suicidal Thoughts and Suicide Attempts in People Who Gamble Based on Biological-Psychological-Social Variables: A Machine Learning Study

Recent research has shown that people who gamble are more likely to have suicidal thoughts and attempts compared to the general population. Despite the advancements made, no study to date has predicted suicide risk factors in people who gamble using machine learning algorithms. Therefore, current study aimed to identify the most critical predictors of suicidal ideation and suicidal attempts among people who gamble using a machine learning approach. An online survey conducted a cross-sectional analysis of 741 people who gamble (mean age: 25.9 ± 5.56). To predict the risk of suicide attempts and ideation, we employed a comprehensive set of 40 biological, psychological, social, and socio-demographic variables. The predictive models were developed using Logistic Regression, Random Forest (RF), robust eXtreme Gradient Boosting (XGBoost), and ensemble machine learning algorithms. Data analysis was performed using R-Studio software. Random Forest emerged as the top-performing algorithm for predicting suicidal ideation, with an impressive AUC of 0.934, sensitivity of 0.7514, specificity of 0.9885, PPV of 0.9473, and NPV of 0.9347. Across all models, dissociation, depression, and anxiety symptoms consistently emerged as crucial predictors of suicidal ideation. However, for suicide attempt prediction, all models exhibited weaker performance. XGBoost showed the best performance in this regard, with an AUC of 0.663, sensitivity of 0.78, specificity of 0.8990, PPV of 0.34, NPV of 0.984, and accuracy of 0.8918. Depressive symptoms and rumination severity were highlighted as the most important predictors of suicide attempts according to this model. These findings have important implications for clinical practice and public health interventions. Machine learning could help detect individuals prone to suicidal ideation and suicide attempts among people who gamble, assisting in creating tailored prevention programs to address future suicide risks more effectively.

Investigating the Mediating Role of Mental Disorders in the Relationship Between Early Sexual Intercourse and Intentional Self-Harm: A Two-Step and Multivariable Mendelian Randomization Study

BACKGROUND

Epidemiological studies have established an association between early sexual intercourse and intentional self-harm. However, the causal mechanisms, particularly the role of mental health disorders, remain elusive.

METHODS

In this Mendelian randomization (MR) study, we leveraged genome-wide association study data from multiple sources. Age at first sexual intercourse (AFSI) statistics were derived from the UK Biobank, encompassing up to 406,457 participants of European ancestry. Intentional self-harm (ISH) genome-wide association study (GWAS) data were obtained from the FinnGen Biobank, comprising 218,792 European-descent individuals. We investigated the causal relationship between AFSI and ISH and quantified the mediating effects of major depressive disorder (MDD; n = 173,005), schizophrenia (SCZ; n = 127,906), and attention deficit hyperactivity disorder (ADHD; n = 55,374). Both two-step and multivariable MR approaches were employed to estimate the mediation effects of these psychiatric disorders.

RESULTS

The F-statistics of all retained SNPs are over 10, indicating our study has no weak instrument bias. The odds ratio (OR) indicated that early sexual intercourse substantially increases the risk of ISH (IVW: OR = 0.60, 95% CI = 0.54-0.66, p < 0.05). Specifically, MDD was found to mediate 31% of this effect and SCZ 12%, collectively accounting for 46% of the total effect.

CONCLUSIONS

Early sexual intercourse is associated with an increased risk of intentional self-harm, potentially mediated by psychiatric disorders. These findings emphasize the need for mental health screening and early intervention in adolescents with early sexual debuts.

Hospitalization for SARS-CoV-2 and the risk of self-harm readmission: a French nationwide retrospective cohort study

AIMS

The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the risk of self-harming behaviours warrants further investigation. Here, we hypothesized that people with a history of hospitalization for self-harm may be particularly at risk of readmission in case of SARS-CoV-2 hospitalization.

METHODS

We conducted a retrospective analysis based on the French national hospitalization database. We identified all patients hospitalized for deliberate self-harm (10th edition of the International Classification of Diseases codes X60-X84) between March 2020 and March 2021. To study the effect of SARS-CoV-2 hospitalization on the risk of readmission for self-harm at 1-year of the inclusion, we performed a multivariable Fine and Gray model considering hospital death as a competing event.

RESULTS

A total of 61,782 individuals were hospitalized for self-harm. During the 1-year follow-up, 9,403 (15.22%) were readmitted for self-harm. Between inclusion and self-harm readmission or the end of follow-up, 1,214 (1.96% of the study cohort) were hospitalized with SARS-CoV-2 (mean age 60 years, 52.9% women) while 60,568 were not (mean age 45 years, 57% women). Multivariate models revealed that the factors independently associated with self-harm readmission were: hospitalization with SARS-CoV-2 (adjusted hazard ratio (aHR) = 3.04 [2.73-3.37]), psychiatric disorders (aHR = 1.61 [1.53-1.69]), self-harm history (aHR = 2.00 [1.88-2.04]), intensive care and age above 80.

CONCLUSIONS

In hospitalized people with a personal history of self-harm, infection with SARS-CoV-2 increased the risk of readmission of self-harm, with an effect that seemed to add to the effect of a history of mental disorders, with an equally significant magnitude. Infection may be a significantly stressful condition that precipitates self-harming acts in vulnerable individuals. Clinicians should pay particular attention to the emergence of suicidal ideation in these patients in the aftermath of SARS-CoV-2 infection.

Prediction of borderline personality disorder based on childhood trauma with the mediating role of experiential avoidance

Introduction

Traits of borderline personality disorder are important for the determination of the prognosis of mental illnesses and in evaluating risks of negativity as well as impulsivity. But, there is a lack of information about the distribution characteristics of borderline personality disorder traits and symptoms within clinical groups. The goal of the current study was to predict borderline personality disorder based on childhood trauma, using experiential avoidance as a mediator.

Methods

All male patients hospitalized in local psychiatric health centers with a diagnosis of borderline personality disorder comprised the statistical population of the current study. The number of 60 patients were selected by the purposeful sampling method. The questionnaire included the Childhood Trauma Questionnaire (CTQ), the Experiential Avoidance Questionnaire (AAQ-II), and the Borderline Personality Disorder Symptoms (BSL-23).

Results and discussion

The results demonstrated that there is a considerable and positive relationship between childhood trauma and experiential avoidance (r = 0.711, p< 0.01). In the mediating model, childhood trauma had significant direct predictive effects on borderline personality disorder (β = 0.546, p< 0.01). Also, between childhood trauma and BPD, experienced avoidance acts as a moderating factor. (β = 0.304, p< 0.01).

Risk factors of suicide in prisons: a comprehensive retrospective cohort study in France, 2017-2020

PURPOSE

Suicide is a leading cause of death in prison and the suicide rates are several times higher in the prison population than in the general population in most countries. Of the studies that have investigated risk factors for suicide in prison, few have controlled for possible confounding factors. The aim of this study is to identify risk factors of suicide among people in French prisons, over a four-year period.

METHODS

All incarcerations that occurred in France during 2017-2020 were eligible. Sociodemographic, criminal and prison characteristics were collected for each incarceration from data of the National Prison Service. Survival univariate and multivariate analyses were performed with a Cox regression model.

RESULTS

358,522 incarcerations were included, of which 449 ended in suicide during the follow-up. The median length of prison stay was 5.1 months. The median age at prison entry was 30 years and 95.8% of incarcerations involved men. The overall suicide rate was 173 [157-189] per 100,000 person-years. Factors associated with suicide in the multivariate model (p < 0.05) were the early stage of incarceration and in particular the first week (HR = 7.6 [5.4-10.8]), violent offences and in particular homicide (HR = 3.0 [2.1-4.2]), French (HR = 1.7 [1.2-2.4]) and other European nationalities (HR = 2.1 [1.4-3.3]), age above 40 (HR = 2.0 [1.5-2.6]), pre-trial incarceration (HR = 1.8 [1.4-2.3]), being separated (HR = 1.6 [1.1-2.3] and having a high school diploma (HR = 1.4 [1.0-1.8]).

CONCLUSIONS

Factors associated with suicide in prison are complex and involve individuals' criminal history as well as conditions of incarceration. These characteristics may be relevant to focus suicide prevention efforts.

GLP-1 Receptor Agonist Use and Risk of Suicide Death

Importance

Concerns have been raised regarding a link between use of glucagon-like peptide-1 (GLP-1) receptor agonists and increased risk of suicidality and self-harm.

Objective

To assess the association between use of GLP-1 receptor agonists and the risk of suicide death in routine clinical practice.

Design, Setting, and Participants

This active-comparator new-user cohort study used nationwide register data from Sweden and Denmark from 2013 to 2021. Adults 18 to 84 years old who initiated treatment with GLP-1 receptor agonists or the comparator sodium-glucose cotransporter-2 (SGLT2) inhibitors were included. Data were analyzed from March to June 2024.

Exposure

Initiation of treatment with a GLP-1 receptor agonist or SGLT2 inhibitor.

Main Outcomes and Measures

The primary outcome was suicide death recorded in the cause of death registers. Secondary outcomes were the composite of suicide death and nonfatal self-harm and the composite of incident depression and anxiety-related disorders. Using propensity score weighting, hazard ratios (HRs) with 95% CIs were calculated separately in the 2 countries and pooled in a meta-analysis.

Results

In total, 124 517 adults initiated a GLP-1 receptor agonist and 174 036 initiated an SGLT2 inhibitor; among GLP-1 receptor agonist users, the mean (SD) age was 60 (13) years, and 45% were women. During a mean (SD) follow-up of 2.5 (1.7) years, 77 suicide deaths occurred among users of GLP-1 receptor agonists and 71 suicide deaths occurred among users of SGLT2 inhibitors: weighted incidences were 0.23 vs 0.18 events per 1000 person-years (HR, 1.25; 95% CI, 0.83-1.88), with an absolute difference of 0.05 (95% CI, -0.03 to 0.16) events per 1000 person-years. The HR was 0.83 (95% CI, 0.70-0.97) for suicide death and nonfatal self-harm, and the HR was 1.01 (95% CI, 0.97-1.06) for incident depression and anxiety-related disorders.

Conclusions and Relevance

This cohort study, including mostly patients with type 2 diabetes, does not show an association between use of GLP-1 receptor agonists and an increased risk of suicide death, self-harm, or incident depression and anxiety-related disorders. Suicide death among GLP-1 receptor agonist users was rare, and the upper limit of the confidence interval was compatible with an absolute risk increase of no more than 0.16 events per 1000 person-years.

Suicide in people prescribed opioid-agonist therapy in Scotland, United Kingdom, 2011-2020: A national retrospective cohort study

BACKGROUND AND AIMS

Opioid dependence is associated with an increased risk of suicide. Drug-related mortality among people with opioid dependence in Scotland has more than tripled since 2010; less is known about changes in suicide risk. We aimed to determine if opioid agonist therapy (OAT) in Scotland is protective against suicide and to measure trends in suicide rates in those with opioid dependence over time.

DESIGN

Retrospective cohort study.

SETTING

Scotland, UK.

PARTICIPANTS

46 453 individuals in Scotland who received at least one prescription for OAT between 2011 and 2020 with over 304 000 person-years (pys) of follow-up.

MEASUREMENTS

We calculated standardised mortality ratios (SMR) using the age- and sex-specific suicide rates in Scotland for years 2011-2020. We fitted multivariable competing-risk regression models to estimate suicide rates by OAT exposure and to estimate trends over time, adjusting for potential confounders.

FINDINGS

There were 575 deaths classed as suicide among the cohort and the overall suicide rate was 1.89 (95% confidence interval [CI] = 1.74-2.05) per 1000 pys. Age and sex SMR for suicide was 7.05 times (95% CI = 6.50-7.65) higher than in the general population. After adjustment, OAT was shown to be highly protective against suicide, with rates more than three times greater (adjusted hazard ratio: 3.07; 95% CI = 2.60-3.62) off OAT compared with on OAT. Suicide rates decreased over time, falling from 2.57 (95% CI = 2.19-3.02) per 1000 pys in 2011-12 to 1.48 (95% CI = 1.21-1.82) in 2019-20.

CONCLUSION

People with opioid dependence in Scotland appear to have a greater risk of suicide than the general population. Treatment is protective, with rates of suicide lower among those on opioid agonist therapy. Suicide rates have decreased over time, during a period in which drug-related death rates in Scotland have risen to globally high levels.

The CO-produced Psychosocial INtervention delivered by GPs to young people after self-harm (COPING): protocol for a feasibility study

Background

Self-harm in young people is a growing concern and reducing rates a global priority. Rates of self-harm documented in general practice have been increasing for young people in the UK in the last two decades, especially in 13-16-year-olds. General practitioners (GPs) can intervene early after self-harm but there are no effective treatments presently available. We developed the GP-led COPING intervention, in partnership with young people with lived experience and GPs, to be delivered to young people 16-25 years across two consultations. This study aims to examine the feasibility and acceptability of conducting a fully powered effectiveness trial of the COPING intervention in NHS general practice.

Methods

This will be a mixed-methods external non-randomised before-after single arm feasibility study in NHS general practices in the West Midlands, England. Patients aged 16-25 years who have self-harmed in the last 12 months will be eligible to receive COPING. Feasibility outcomes will be recruitment rates, intervention delivery, retention rates, and completion of follow-up outcome measures. All participants will receive COPING with a target sample of 31 with final follow-up data collection at six months from baseline. Clinical data such as self-harm repetition will be collected. A nested qualitative study and national survey of GPs will explore COPING acceptability, deliverability, implementation, and likelihood of contamination.

Discussion

Brief GP-led interventions for young people after self-harm are needed to address national guideline and policy recommendations. This study of the COPING intervention will assess whether a main trial is feasible.

Registration

Psychiatric disorder and life-event in self harm: A cross-sectional study among clinical population in Bangladesh

Background

Mental illness is an important risk factor for self-harm behavior. However, the association between self-harm behavior and psychiatric disorders has been poorly studied in Bangladesh.

Aims

To determine the prevalence of psychiatric disorders and life-events among patients with a self harm behavior.

Methods

This cross-sectional study was conducted between March 2022 and November 2023. We collected data from 100 patients with self harms from two tertiary care hospital of Dhaka by semi-structured interviews.

Results

Of the 100 cases, 72 were females, 63 % came from semi-urban background. Hanging was the commonest method (31 %) followed cutting and piercing instrument (22 %), and ingestion of Benzodiazepines (20 %). Among the cases, 71 % had at least one psychiatric disorder (Axis I 49 % and Axis II 35 %). In case of life events, 52 % had life-events within immediate 48 h, 15 % in the last one month and 17 % in the last year. Family conflict (30 %) was the commonest risk factor and increased argument with resident family members (38 %) was the commonest life event.

Conclusions

This study revealed a similar proportion of psychiatric disorders revealed in previous studies among suicide attempts. It also unveiled life events in suicide attempts indicating a potential role of life events in suicide attempts in Bangladesh. However, a prudential interpretation is warranted while considering the study results as it was conducted among clinical samples.

'Once you've opened that can of worms': qualitative study to understand why liaison psychiatry staff are not asking about domestic abuse following self-harm

BACKGROUND

Domestic abuse is a significant risk factor for self-harm and suicide. A large proportion of people presenting to healthcare services following self-harm have experienced domestic abuse. In the UK, routine enquiry for domestic abuse is recommended for people who present having self-harmed, but evidence indicates that this is not happening.

AIMS

An exploratory qualitative study to explore liaison psychiatry staff experiences of asking about domestic abuse, including the barriers and challenges to asking.

METHOD

Semi-structured qualitative interviews with active adult liaison psychiatry staff in the UK. Recruitment was via online platforms and professional networks. A reflexive thematic analysis of the narratives was carried out.

RESULTS

Fifteen participants were interviewed across a variety of disciplines (ten nurses, four doctors, one social worker). The generated themes include the following: asking about domestic abuse - the tension between knowing and doing; 'delving deeper' and the fear of making things worse; the entanglement of shame, blame and despondency; domestic abuse was different from other clinical problems (mental illness/substance misuse); and biases, myths and misassumptions guiding practice. Participants indicated the need for better training and education, and clear protocols for eliciting and acting on disclosures.

CONCLUSION

There is a clear need to improve the support offered to victim-survivors of domestic abuse who self-harm and present to healthcare services. National implementation of education and training to better equip liaison psychiatry teams with the skills and knowledge to sensitively support victim-survivors of domestic abuse is required.

Exploring General Practitioners' Management of Self-Harm in Young People: A Qualitative Study

BACKGROUND

General practitioners (GPs) are key to the frontline assessment and treatment of young people after self-harm. Young people value GP-led self-harm care, but little is known about how GPs manage young people after self-harm.

AIM

This study aimed to understand the approaches of GPs to self-harm in young people and explore their perspectives on ways they might help young people avoid repeat self-harm.

METHODS

We conducted semi-structured interviews with GPs from the National Health Service in England in 2021. GPs were recruited from four geographically spread clinical research networks and a professional special interest group. Data were analysed using reflexive thematic analysis. The study's patient and public involvement and community of practice groups supported participant recruitment and data analysis.

RESULTS

Fifteen interviews were undertaken with a mean age of participants being 41 years and a breadth of experience in practice ranging from 1 to 22 years. Four themes were generated: GPs' understanding of self-harm; approaches to managing self-harm; impact of COVID-19 on consultations about self-harm; and ways to avoid future self-harm.

CONCLUSION

Negative attitudes towards self-harm within clinical settings are well documented, but GPs said they took self-harm seriously, listened to young people, sought specialist support when concerned and described appropriate ways to help young people avoid self-harm. GPs felt that relationship-based care is an important element of self-harm care but feared remote consultations for self-harm may impede on this. There is a need for brief GP-led interventions to reduce repeat self-harm in young people.

PATIENT AND PUBLIC CONTRIBUTION

A study advisory group consisting of young people aged 16-25 years with personal experience of self-harm and parents and carers of young people who have self-harmed designed the recruitment poster of this study, informed its topic guide and contributed to its findings.

Preventing suicide: a public health approach to a global problem

Suicide is prevalent in all countries and is largely preventable. The causes of suicide are multiple and varied. Social determinants of suicide are crucial, but to date these have received insufficient policy attention. This paper, which is the first in a Series on taking a public health approach to suicide prevention, argues for a major change in the way we think about suicide and its prevention. This Series paper presents a public health model that emphasises the broad social determinants of suicide and describes a framework through which these might be addressed. We argue for a policy reset that would take national suicide prevention strategies to the next level. Such policies would become whole-of-government endeavours that tackle major social determinants of suicide at their source. We also argue that high-quality data and methodologically rigorous evaluation are integral to this public health approach.

Perspectives on Self-Harm and Suicidal Ideation in Nigeria: A Mixed-Methods Study of Patients, Family Caregivers, Clinicians, and the Public

BACKGROUND

Suicide and self-harm are global disease burden that contributes significantly to years of lost life and mortality. Despite the increasing rates of suicide and self-harm in Nigeria, this topic is understudied.

METHODS

A mixed-methods design was adopted. Study 1 interviewed n = 18 participants (n = 11 clinicians; n = 5 patients with a history of self-harm and suicide ideation; and n = 2 caregivers). All interviews were audio-recorded, transcribed verbatim, and analyzed using IPA. Study 2 surveyed n = 562 non-clinical sample about their tolerance toward self-harm and the data was analyzed using One-way ANOVA in SPSS.

RESULTS

Study 1 qualitative findings showed substance use, perceived rejection and social isolation were considered predisposing factors for suicide and self-harm. Cultural and religious beliefs shaped help-seeking behaviours. Although Study 2 found no significant differences in demographic characteristics concerning public tolerance toward persons with a history of self-harm, 64% believed that individuals who died by suicide would face punishment after death; 51% believed that victims of attempted suicide are a source of shame to their families; and 33.8% agreed that dying by suicide is the correct behaviour.

CONCLUSIONS

Patients with a history of self-harm and suicidal ideation consider family members and close friends as valuable sources of support. Due to the potential clinical implication of cultural and religious beliefs, as shown in the present study's findings, the authors recommend a co-development of culturally appropriate psychological intervention for persons with a history of self-harm and suicidal ideation to be tested in randomized control trials.

Solution-focused approaches for treating self-injurious thoughts and behaviours: a scoping review

BACKGROUND

Self-injurious thoughts and behaviours are a major global public health concern, not least because they are one of suicide's strongest predictors. Solution-focused approaches are a psychotherapeutic approach currently being used to treat individuals with self-injurious thoughts and behaviours but there is little published evidence of their use. We conducted a scoping review to provide a comprehensive overview of how solution-focused approaches are being used to treat self-injurious thoughts and behaviours.

METHODS

Publications describing a solution-focused approach being delivered to any individuals experiencing any form of self-injurious thought and/or behaviour were eligible for inclusion. Five databases were searched (EMBASE, PubMed, Web of Knowledge, PsycINFO, and Google Scholar) from inception to August 2024. Search terms contained keywords relating to both solution-focused and self-injurious thoughts and/or behaviours. Data were analysed using relevant steps from a narrative synthesis approach to summarise the participants, concepts, context and outcomes described in the included publications.

RESULTS

Twenty-four publications were included in the review. Publications demonstrated a global reach although the majority were published in the UK and USA. Five publications formally assessed and reported outcomes; two randomised controlled trials, one experimental pilot study, one case study, and one single group study. Only the Beck Depression Inventory was collected in more than one study (n = 4), with a range of other psychopathology and wellbeing-related measures. Three studies reported qualitative data, finding positive perceptions of the approaches by patients and clinicians. Fifty-one unique components were identified within solution-focused approaches. Often specific adaptations were described, or components were introduced, that specifically addressed suicide or self-harm. For example, identifying and working on goals related to reducing or stopping self-harm, or scaling questions that assess how suicidal someone currently feels on a 0 to 10 scale.

CONCLUSIONS

This review demonstrates the application of solution-focused approaches for treating individuals with self-injurious thoughts and behaviours. The findings provide a comprehensive overview of how these approaches are delivered. The lack of outcome data and empirical studies highlights a need for more formalised evidence.

Financial Stress Amongst People Who Self-Harm in Sri Lanka

OBJECTIVE

Socioeconomic status deprivation is known to be associated with self-harm in Western countries but there is less information about this association in Low and Middle Income Countries (LMIC). One way of investigating this is to assess the prevalence of indicators of financial stress in people who self-harm. We have assessed the prevalence and correlates of day-to-day financial hardships amongst individual presenting with non-fatal self-harm to hospitals in Sri Lanka.

METHODS

Data on non-fatal self-harm presentations were collected from an ongoing surveillance project in 52 hospitals in Sri Lanka. A questionnaire captured data on two forms of financial stress: unmet need (i.e., costs and bills that cannot be paid) and required support (i.e., steps taken to cover costs, such as selling belongings). Additional data on demographic, economic and clinical characteristics were also collected.

RESULTS

The sample included 2516 individuals. Both forms of financial stress were very common, with pawning/selling items (47%) and asking family or friends for money (46%) in order to pay bills or cover costs being commonly reported. Greater financial stress was associated with being aged 26-55 years, limited education, and low socioeconomic position. Financial stress was greater in women than men after adjusting for other factors.

CONCLUSION

The results indicate that financial stress is commonly reported amongst individuals presenting to hospital with non-fatal self-harm in Sri Lanka, especially women. The research highlights a need to attend to financial stress both within self-harm prevention and aftercare.

Recent Breakthroughs in Genetic and Brain Structural Correlates of Suicidal Behaviors: A Short Review

Suicide accounts for more than 700,000 deaths annually and is the fourth leading cause of death among individuals aged 15 to 29 years. Despite years of research to understand the etiology and pathophysiology of suicidal behavior, many questions remain unresolved-for example, whether suicidal behavior has a unique genetic or neurobiological basis and how these differ from related psychiatric conditions, such as depression, bipolar disorder, schizophrenia, etc. Identifying these biological correlates is paramount to advancing our understanding of the mechanisms that underlie suicidal behavior. In this literature review, we examine the complex nature of suicidal thoughts and behaviors, integrating insights from large-scale genetic and neuroimaging studies published between 2018 and 2023. Recent genome-wide association studies have uncovered specific genomic loci associated with specific suicidal behaviors. However, there is a need for larger and more diverse samples in these studies to overcome challenges in replicability and generalizability. Neuroimaging studies have also revealed structural brain differences associated with suicidal behavior, thanks to international consortium-level efforts that have enabled data sharing, collaboration, and coordinated analyses that improve the robustness and reliability of findings. Despite promising progress in identifying the genetic and neurobiological underpinnings of suicidal behavior, the translation of these advances and findings into effective suicide prevention strategies and clinical tools remains a crucial challenge. Consequently, future studies must focus on integrating biological elements into an improved mechanistic understanding of the etiology of suicidal behavior, which in turn can translate into new strategies for early detection, intervention, and treatment.

Help-Seeking Needs Related to Suicide Prevention for Individuals in Contact With Mental Health Services: A Rapid Scoping Review

INTRODUCTION

Prior mental healthcare utilisation presents an important window of opportunity for providing suicide prevention interventions. To date, no reviews have consolidated the help-seeking needs of individuals in contact with mental health services. This warrants further attention given this group may have different needs for interventions compared with the general population who have not sought help previously.

AIM

The purpose of this rapid scoping review was to summarise the available literature on help-seeking needs related to suicide prevention among individuals in contact with mental health services from healthcare settings.

METHOD

Cochrane rapid review and Joanna Briggs Institute scoping review methodologies were adapted, and databases, including MEDLINE, Scopus, CINAHL, PsycInfo and EMBASE, were searched.

RESULTS

A total of 42 primary studies were included in analysis. Reported barriers and facilitators to help-seeking behaviours identified within studies were mapped onto the socio-ecological model. Barriers and facilitators identified included knowledge and attitudes towards healthcare utilisation, family and peer support, interactions with healthcare professionals, provision of holistic care, and the creation of a supportive atmosphere and safe space to promote open discussions of suicide-related concerns.

DISCUSSION

The findings of this review offer valuable insights into areas for improvement in addressing help-seeking needs for individuals who are in contact with health services related to suicide prevention.

IMPLICATION FOR RESEARCH

The findings serve as a foundation for shaping mental health initiatives informing approaches and care delivery tailored towards individuals who are in contact with health services. The reported barriers and facilitators offer insights to inform the development of mental health support tools to enhance care and considerations for evaluations.

Using a Digital Mental Health Intervention for Crisis Support and Mental Health Care Among Children and Adolescents With Self-Injurious Thoughts and Behaviors: Retrospective Study

BACKGROUND

Self-injurious thoughts and behaviors (SITBs) are increasing dramatically among children and adolescents. Crisis support is intended to provide immediate mental health care, risk mitigation, and intervention for those experiencing SITBs and acute mental health distress. Digital mental health interventions (DMHIs) have emerged as accessible and effective alternatives to in-person care; however, most do not provide crisis support or ongoing care for children and adolescents with SITBs.

OBJECTIVE

To inform the development of digital crisis support and mental health care for children and adolescents presenting with SITBs, this study aims to (1) characterize children and adolescents with SITBs who participate in a digital crisis response service, (2) compare anxiety and depressive symptoms of children and adolescents presenting with SITBs versus those without SITBs throughout care, and (3) suggest future steps for the implementation of digital crisis support and mental health care for children and adolescents presenting with SITBs.

METHODS

This retrospective study was conducted using data from children and adolescents (aged 1-17 y; N=2161) involved in a pediatric collaborative care DMHI. SITB prevalence was assessed during each live session. For children and adolescents who exhibited SITBs during live sessions, a rapid crisis support team provided evidence-based crisis support services. Assessments were completed approximately once a month to measure anxiety and depressive symptom severity. Demographics, mental health symptoms, and change in the mental health symptoms of children and adolescents presenting with SITBs (group with SITBs) were compared to those of children and adolescents with no SITBs (group without SITBs).

RESULTS

Compared to the group without SITBs (1977/2161, 91.49%), the group with SITBs (184/2161, 8.51%) was mostly made up of adolescents (107/184, 58.2%) and female children and adolescents (118/184, 64.1%). At baseline, compared to the group without SITBs, the group with SITBs had more severe anxiety and depressive symptoms. From before to after mental health care with the DMHI, the 2 groups did not differ in the rate of children and adolescents with anxiety symptom improvement (group with SITBs: 54/70, 77% vs group without SITBs: 367/440, 83.4%; χ21=1.2; P=.32) as well as depressive symptom improvement (group with SITBs: 58/72, 81% vs group without SITBs: 255/313, 81.5%; χ21=0; P=.99). The 2 groups also did not differ in the amount of change in symptom severity during care with the DMHI for anxiety (t80.20=1.37; P=.28) and depressive (t83.75=-0.08; P=.99) symptoms.

CONCLUSIONS

This study demonstrates that participation in a collaborative care DMHI is associated with improved mental health outcomes in children and adolescents experiencing SITBs. These results provide preliminary insights for the use of pediatric DMHIs in crisis support and mental health care for children and adolescents presenting with SITBs, thereby addressing the public health issue of acute mental health crisis in children and adolescents.

Work-related suicide: Evolving understandings of etiology & intervention

Previously published analyses of suicide case investigations suggest that work or working conditions contribute to 10%-13% of suicide deaths. Yet, the way in which work may increase suicide risk is an underdeveloped area of epidemiologic research. In this Commentary, we propose a definition of work-related suicide from an occupational health and safety perspective, and review the case investigation-based and epidemiologic evidence on work-related causes of suicide. We identified six broad categories of potential work-related causes of suicide, which are: (1) workplace chemical, physical, and psychosocial exposures; (2) exposure to trauma on the job; (3) access to means of suicide through work; (4) exposure to high-stigma work environments; (5) exposure to normative environments promoting extreme orientation to work; and (6) adverse experiences arising from work-related injury or illness. We summarise current evidence in a schema of potential work-related causes that can also be applied in workplace risk assessment and suicide case investigations. There are numerous implications of these findings for policy and practice. Various principle- and evidence-based workplace intervention strategies for suicide prevention exist, some of which have been shown to improve suicide-prevention literacy, reduce stigma, enhance helping behaviours, and in some instances maybe even reduce suicide rates. Prevailing practice in workplace suicide prevention, however, overly emphasises individual- and illness-directed interventions, with little attention directed to addressing the working conditions that may increase suicide risk. We conclude that a stronger emphasis on improving working conditions will be required for workplace suicide prevention to reach its full preventive potential.

Ethnicity and suicide in England and Wales: a national linked cohort study

BACKGROUND

Understanding of ethnic disparities in suicide in England and Wales is poor as ethnicity is not recorded on death certificates. Using linked data, we examined variations, by sex, in suicide rates in England and Wales by ethnicity and migrant and descendant status.

METHODS

Using the Office for National Statistics 2012-19 mortality data linked to the 2011 census from the Public Health Research Database, we calculated the age-standardised suicide rates by sex for each of the 18 self-identified ethnicity groups in England and Wales. We present rates by age, sex, and methods used for suicide by ethnic group. We estimated age-adjusted and sex-adjusted incidence rate ratios (IRRs) using Poisson regression models for each minority ethnic group compared with the majority population. We involved people with lived experience in the research.

FINDINGS

Overall, 31 644 suicide deaths occurred over the study period, including 3602 (11%) in people from minority ethnic backgrounds, with a mean age of death of 43·3 years (SD 17·0, range 13-96). Almost all minority ethnic groups had a lower rate of suicide than the White British majority, apart from individuals who identified as being from a Mixed heritage background or White Gypsy or Irish Travellers. In females who identified as Mixed White and Caribbean, the suicide IRR was 1·79 (95% CI 1·45-2·21) compared with the White British majority; in those who identified as White Gypsy or Irish Travellers, the IRR was 2·26 (1·42-3·58). Rates in males identifying as from these two groups and those identifying as White Irish were similar to the White British majority. Compared with the non-migrant population, migrants had a lower rate of suicide regardless of ethnicity, but in the descendant population, people from a Mixed ethnicity background had a higher risk of suicide than the White British majority.

INTERPRETATION

There are ethnic disparities in suicide mortality in England and Wales, but the reasons for this are unclear. The higher rate in previously overlooked minority ethnic groups warrants further attention.

Improving responsible Media Reporting on Student Suicide to Reduce Negative Public Opinion: Text Mining Based on Sina Weibo in China

The aims of this study were to explore whether student suicide reporting is consistent with media recommendations for suicide reporting; analyze public opinion and sentiments toward student suicide reports. A keyword search was performed on the WeiboReach platform. This study included 113 student suicide report posts and 176,262 readers' comments on suicide news reports. Hierarchical generalized linear modeling was used to analyze the relationships between adherence to reporting recommendations and negative emotions in readers' comments. None of the media reporting of student suicide was consistent with all of the media recommendations for suicide reporting. Netizens were less likely to post negative comments when the reports describe the suicide method used (OR 1.169, 95% CI 1.022∼1.337), and not specifying the cause of suicide was a protective factor for public negative emotion (OR 0.799, 95% CI 0.707, 0.905). The findings suggest improving responsible media reporting on student suicide to reduce negative public emotion.

The relationship between childhood maltreatment and self-harm: the mediating roles of alexithymia, dissociation, internalizing and posttraumatic symptoms

Background: Although childhood maltreatment is associated with later self-harm, the mechanism through which it might lead to self-harm is not completely understood. The purpose of this study was to examine the roles of alexithymia, dissociation, internalizing and posttraumatic symptoms in the association between exposure to childhood maltreatment and subsequent self-harm.Methods: A total of 360 adolescents were asked to complete the Childhood Trauma Questionnaire, the Toronto Alexithymia Scale, the Dissociative Experience Scale, the Somatoform Dissociation Questionnaire-20, the Posttraumatic Stress Checklist for DSM-5, and the Deliberate Self-Harm Inventory.Results: Results of structural equation modelling analysis revealed the significant mediation effects of alexithymia and dissociative symptoms in the relationship between childhood maltreatment and self-harm, while internalizing and posttraumatic symptoms did not significantly mediate.Conclusion: The findings indicate that alexithymia and dissociative symptoms may be proximal mechanisms linking maltreatment exposure and adolescence self-harm.

The Relational Approach to Treating Self-Harm (RELATE): study protocol for a feasibility randomised controlled trial study of cognitive analytic therapy for adults who self-harm versus treatment at usual

BACKGROUND

Self-harm is a prevalent behaviour that has a major detrimental impact on a person's life. Psychological therapies have the potential to help, but evidence of effective interventions remains limited. Access and acceptability of interventions can also be a significant challenge, with individuals either being unable to access help or having to endure long waiting lists. Cognitive analytic therapy (CAT) is a time-limited and relationally-focused psychotherapy that may provide a valuable treatment option for people who self-harm. This protocol outlines the methodology for the first feasibility randomised controlled trial (RCT) of CAT for adults that self-harm. The trial will aim to determine the feasibility, acceptability and safety of undertaking larger-scale evaluations of CAT for self-harm within an RCT context.

METHOD

An RCT design with 1:1 allocation to CAT plus treatment as usual (TAU) or TAU alone. Participants will be adult outpatients with three or more instances of self-harm in the past year (target sample of n = 60). CAT will be 8 one-to-one weekly 60-min sessions plus a follow-up session up to 8 weeks after the last session. Assessments will occur at baseline, 12 weeks and 18 weeks after randomisation. Qualitative interviews with participants will gain insights into the feasibility and acceptability of CAT. Feasibility outcomes will be judged against progression criteria.

DISCUSSION

CAT may be an effective and accessible treatment option for people who self-harm, providing a more relationally orientated alternative to more behavioural therapies. The proposed feasibility RCT is an important first step in evaluating CAT as a treatment for self-harm.

TRIAL REGISTRATION

The trial was pre-registered (21/10/22) on ISR CTN (ISRCTN code: ISRCTN75661422).

The functional connectivity of the right superior temporal gyrus is associated with psychological risk and resilience factors for suicidality

INTRODUCTION

Suicide attempters show increased activation in the right superior temporal gyrus (rSTG). Here, we investigated the rSTG functional connectivity (FC) to identify a functional network involved in suicidality and its associations with psychological suicidality risk and resilience factors.

METHODS

The resting state functional magnetic resonance imaging data of 151 healthy individuals from the Human Connectome Project Young Adult database were used to explore the FC of the rSTG with itself and with the rest of the brain. The correlation between the rSTG FC and loneliness and purpose in life scores was assessed with the NIH Toolbox. The effect of sex was also investigated.

RESULTS

The rSTG had a positive FC with bilateral cortical and subcortical regions, including frontal, temporal, parietal, occipital, limbic, and cerebellar regions, and a negative FC with the medulla oblongata. The FC of the rSTG with itself and with the left central operculum were associated with loneliness scores. The within rSTG FC was also negatively correlated with purpose in life scores, although at a trend level. We did not find any effect of sex on FC and its associations with psychological factors.

LIMITATIONS

The cross-sectional design, the limited age range, and the lack of measures of suicidality limit the generalizability of our findings.

CONCLUSIONS

The rSTG functional network is associated with loneliness and purpose in life. Together with the existing literature on suicide, this supports the idea that the neural activity of rSTG may contribute to suicidality by modulating risk and resilience factors associated with suicidality.

Travel Distance to Hospital Is Associated With Self-Harm Hospital Presentation But Not Suicide

Background: Travel distance to hospital emergency departments (EDs) may be a more influential factor in the spatial variation in hospital-presenting self-harm than for suicide deaths. Aims: We investigated the associations of travel distance to the nearest ED with self-harm hospital presentations and suicides in a large city in Taiwan. Method: Data for self-harm and suicide were extracted from Taiwan's National Suicide Surveillance System (2012-2016). Results: Adjusted analyses using Bayesian hierarchical models showed that a longer travel distance to the nearest hospital ED was associated with lower self-harm hospital presentation rates but not suicide rates. Limitations: This is an ecological study; the area-level associations could not be directly implied at the individual level. Conclusion: Living in remote neighborhoods could be a barrier to seeking medical help after self-harm, and this has implications for suicide, surveillance, prevention and intervention strategies.

Predicting Suicidal Ideation, Planning, and Attempts among the Adolescent Population of the United States

Suicide is the second leading cause of death among individuals aged 5 to 24 in the United States (US). However, the precursors to suicide often do not surface, making suicide prevention challenging. This study aims to develop a machine learning model for predicting suicide ideation (SI), suicide planning (SP), and suicide attempts (SA) among adolescents in the US during the coronavirus pandemic. We used the 2021 Adolescent Behaviors and Experiences Survey Data. Class imbalance was addressed using the proposed data augmentation method tailored for binary variables, Modified Synthetic Minority Over-Sampling Technique. Five different ML models were trained and compared. SHapley Additive exPlanations analysis was conducted for explainability. The Logistic Regression model, identified as the most effective, showed superior performance across all targets, achieving high scores in recall: 0.82, accuracy: 0.80, and area under the Receiver Operating Characteristic curve: 0.88. Variables such as sad feelings, hopelessness, sexual behavior, and being overweight were noted as the most important predictors. Our model holds promise in helping health policymakers design effective public health interventions. By identifying vulnerable sub-groups within regions, our model can guide the implementation of tailored interventions that facilitate early identification and referral to medical treatment.

Anxious and depressive symptoms and health-related quality of life in a cohort of people who recently attempted suicide: A network analysis

BACKGROUND

Suicide is an international health concern with immeasurable impact from the perspective of human and social suffering. Prior suicide attempts, anxious and depressive symptoms, and relatively lower health-related quality of life (HRQoL) are among the most replicated risk factors for suicide. Our goal was to visualize the distribution of these features and their interconnections with use of a network analysis approach in individuals who recently attempted suicide.

METHODS

Individuals with a recent suicide attempt were recruited from nine University Hospitals across Spain as part of the SURVIVE cohort study. Anxious and depressive symptoms, and perceived HRQoL were included in the network analysis. Network structures were estimated with the EBICglasso model. Centrality measures and bridge symptoms connecting communities were explored. Subnetworks comparing younger and older individuals, and women and men were analyzed.

RESULTS

A total of 1106 individuals with a recent suicide attempt were included. Depressed mood was the symptom with the greatest influence in the overall network, followed by anxiety symptoms such as feeling nervous, worrying, restless, and having difficulties to relax. Perceived general health was associated with increased suicidal ideation in the whole sample. Older people showed a specific connection between perceived general health and depressed mood.

LIMITATIONS

The cross-sectional design does not allow determination of established causality.

CONCLUSIONS

Depressed mood was the core network's symptom and, therefore, an important target in the management and prevention of suicide. HRQoL had more influence on the network of older populations, in which it should be a primary focus.

Characteristics of drug overdose suicide attempts presenting to the psychiatric emergency department of Beijing Anding Hospital

BACKGROUND

Overdose-related suicide attempts represent a significant portion of self-harm presentations in the psychiatric emergency department (ED). Identifying specific patient characteristics associated with these attempts holds promise for pinpointing drug classes with elevated risk and paving the way for tailored suicide prevention interventions. This study aims to examine the demographic profiles of ED patients who had experienced overdose-related suicide attempts.

METHODS

This retrospective study was conducted at Beijing Anding Hospital, Capital Medical University, from January 2020 to December 2021. Patients with psychiatric drug overdose suicide attempts presenting to the psychiatric ED were included. Sociodemographic characteristics and the specific classes of drugs involved were collected, and analysed descriptively.

RESULTS

This study examined 252 overdose patients, excluding 51 patients treated with alcohol or nonpsychiatric drugs, and a total 201 cases were included. The mean age of the patients was 28 ± 16 years (median 23, range 12-78), and 82% (n = 165) of the sample were females. Notably, nearly half (45%) of the patients were aged ≤ 20 years. While the number of cases decreased with increasing age, a significant increase was observed in 2021 compared to 2020. Benzodiazepines (BZDs) were the most frequently implicated substance class (n = 126, 63%), followed by antidepressants (n = 96, 48%), antipsychotics (n = 44, 22%), Z-drugs (n = 43, 21%), and mood stabilizers (n = 36, 18%). For adolescents, antidepressants (n = 52, 71%) overtook BZDs (n = 38, 52%) as the most common drug. The monthly distribution of cases revealed peaks in April and November. Furthermore, 21% (n = 42) of patients ingested more than two psychotropic medications concurrently. Finally, approximately half (n = 92) of the patients required inpatient admission for further treatment. Comparisons between hospitalized and nonhospitalized patients did not reveal any significant differences.

CONCLUSIONS

The present study revealed a greater prevalence of suicide overdose attempts among young females receiving prescriptions for antidepressants and/or BZDs. This finding suggests a potential need for enhanced monitoring of suicidal behaviour in this specific population when prescribing psychotropic medications. These findings contribute to the growing body of knowledge regarding drug overdose suicide attempts in psychiatric emergency settings and underscore the importance of further research to develop targeted prevention interventions.

Involvement of propranolol in suicides: cross-sectional study using coroner-reported data

BACKGROUND

Propranolol is a beta-blocker medication indicated mostly for heart rhythm conditions and for physical symptoms of anxiety. Prescriptions for propranolol in the UK have increased since 2008. Recently, there have been concerns about the involvement of propranolol in intentional poisonings, but such deaths are not routinely reported. Therefore, use of coroner-reported and toxicology data enables unique investigation into the scale of involvement of propranolol in suicide.

AIMS

To describe the extent to which propranolol is involved in suicides, including patterns over time and characteristics of people whose suicide involved propranolol compared with other suicides.

METHOD

Data were derived from the National Programme on Substance Use Mortality (NPSUM). All suicides and deaths of undetermined intent between 2010 and 2021 in England, Wales and Northern Ireland were extracted, and a subset was identified where propranolol was involved in death.

RESULTS

There were 4473 suicides of which 297 (6.6%) involved propranolol, with the proportion involving propranolol nearly quadrupling during the study period (3.4% v. 12.3%). Compared with all other suicides, a greater proportion of propranolol suicides were in women (56.6% v. 37.1%) and in people with diagnoses of depression (39.1% v. 27.1%) and anxiety (22.2% v. 8.6%). When suicide involved propranolol, an antidepressant was detected at post-mortem in 81.8% of deaths, most commonly a selective serotonin reuptake inhibitor (SSRIs) (51.5%), and most often citalopram (24.6%).

CONCLUSIONS

A small number, but increasing proportion, of suicides reported to the NPSUM involve propranolol. Vigilance to the combined toxicity profile of medicines used alongside propranolol may be pertinent.

Suicide among migrants: a comprehensive narrative review of literature

Suicidality among migrants represents a multifaceted and complex issue with significant implications and challenges for public mental health and policies. This narrative review aims to explore the factors contributing to suicidality within the migrant groups, consequently highlighting the need for tailored interventions and supporting strategies. Firstly, we reviewed the evidences on the prevalence of suicidal ideation, attempted suicides, and deaths by suicide among migrants. The results were extremely heterogeneous, mostly depending on the different migrant group considered. Significant differences in suicide risk have been found depending on the legal status of migrants and their country of origin/migration. The second section explored the protective and risk factors for suicidal ideation and behaviours in different migrant groups. The analysis concluded that a set of factors may interact in various ways, contributing to a heterogeneous and complex framework underpinning the phenomenon of suicide. Migration itself may be a challenging and traumatizing experience, characterized by social isolation, cultural dislocation and adjustment, as well as economic and financial distress, all of which may exacerbate pre-existing mental health vulnerabilities or trigger new mental disorders. Acculturative stress, discrimination, and language barriers further compound these challenges, often hindering access to mental health services.

Effects of melancholic features on positive and negative suicidal ideation in patients with treatment-resistant depression and strong suicidal ideation receiving low-dose ketamine infusion

The role of melancholic features on the antisuicidal effect of 0.5 mg/kg ketamine infusion has remained unclear in patients with treatment-resistant depression (TRD) and strong suicidal ideation (SI). Whether ketamine diminishes suicidal ideation in patients with TRD-SI was also unknown. We enrolled 84 patients with TRD-SI, including 27 with melancholic features and 57 without, and then randomly administered a single infusion of 0.5 mg/kg ketamine or 0.045 mg/kg midazolam. The clinician-rated Montgomery-Åsberg Depression Rating Scale (MADRS) item 10, Columbia Suicide Severity Rating Scale-Ideation Severity Subscale (CSSRS-ISS), and self-reported Positive and Negative Suicide Ideation Inventory (PANSI) were used to assess suicidal symptoms from baseline to day 7. Generalized estimating equation models showed that only patients without melancholic features (MADRS item 10: infusion group effect, p = 0.017; CSSRS-ISS: infusion group × time effect, p = 0.008; PANSI-negative suicidal ideation: infusion group effect, p = 0.028) benefited from the antisuicidal effect of low-dose ketamine. The PANSI-positive ideation scores were higher in the ketamine group than in the midazolam group (p = 0.038) for patients with melancholic features. Additional studies are necessary to clarify the neuromechanisms underlying the ketamine-related positive effect against SI and antisuicidal effects among patients with TRD-SI. Additional studies are necessary to clarify the neuromechanisms underlying the ketamine-related positive effect against SI and antisuicidal effects among patients with TRD-SI.

Exploring suicide resilience experiences in Chinese youth after self-poisoning: A qualitative study

OBJECTIVE

This inquiry probes the suicide resilience experiences in suicide attempts by self-poisoning among Chinese youth. The study's goal is to provide healthcare professionals with critical insights to develop effective interventions that enhance suicide prevention measures and diminish the likelihood of subsequent attempts.

METHODS

Utilizing a qualitative phenomenological approach, we conducted semi-structured interviews with 12 youths (Mean age = 21.1 ± 2.8 years; n = 7 females) who survived suicide attempts by self-poisoning. Data analysis was performed using Colaizzi's seven-step method, a rigorous method entailing iterative reading for the extraction of key statements and the distillation of thematic essence.

RESULTS

Four primary themes with ten sub-themes were extracted: (1) New understanding of life (cherish life, and meaning of life), (2) Self-Reconciliation (self-acceptance, self-understanding, and self-openness), (3) Personal empowerment (increased self-reliance, increased responsibility, and increased emotional regulation), and (4) Life redesigning (faith in the future, and plan for the future).

CONCLUSIONS

The findings reveal a potential for psychological growth and beneficial transformation in youth following suicide attempts by self-poisoning. These insights advocate for the integration of positive psychology principles in therapeutic interventions for this demographic.

Personal and work-related burnout is associated with increased episodes of suicidal ideation or behavior among working adults in Chile

Burnout has been previously associated with suicidal risk factors and suicide itself, but these associations have only focused on work-related burnout among high-demand occupations. We aimed at examining the extent to which personal and/or work-related burnout are associated with suicidal ideation or behavior among working adults in Chile. We conducted a cross-sectional study among 1,970 working adults attending the Hospital del Trabajador in Santiago, Chile, between September 2015 and February 2018, using structured interviews. The Copenhagen Burnout Inventory (CBI) assessed levels of personal and work-related burnout (mild, moderate, and high-to-severe), and the Columbia Suicidal Rating Scale (C-SSRS) measured suicidal ideation or behavior. Multivariable logistic regression models were fit to estimate the magnitude of the association between burnout with suicidal ideation or behavior. After adjusting for putative confounders, moderate and high-to-severe personal burnout were associated with 5.07-fold (95% confidence interval (Al-Halabí et al.): 3.56-7.26) and 10.26-fold (95% CI: 5.75-18.50) increased odds of suicidal ideation or behavior, and high-to-severe work-related burnout associated with 2.47-fold increased odds (95% CI: 1.31-4.68). The dose-response pattern was shown in the association between both types of burnout and suicidal ideation or behavior (p for trend <0.05). Personal and work-related burnout were associated with increased odds of suicidal ideation or behavior in a dose-response manner. Focusing on alleviating burnout levels through mental health services or social support may effectively decrease the prevalence of suicidal ideation or behavior among working adults.

Characteristics and circumstances of rail suicides in England 2019-2021: A cluster analysis and autopsy study

BACKGROUND

Around 4 % of all suicide deaths in Great Britain occur on the railways. This exploratory study was designed to increase understanding of the individuals that take their lives in this way, and the circumstances of their death.

METHOD

Data were obtained from fatality investigation files compiled by the British Transport Police (BTP) relating to suspected suicides on the mainline railway in England from April 2019 to March 2021. Cluster analysis was carried out to identify grouped associations of characteristics and circumstances relating to rail suicide.

RESULTS

A total of 436 files were analysed, representing 93 % of all suspected railway suicides during this period. Cluster analysis identified four groups of almost equal size, distinguished principally by age, living arrangements, employment status and location of death. The study is novel in the way it integrates individual characteristics and circumstances of death. The identified clusters may provide a multidimensional way of conceptualising suicide risk that could inform more targeted interventions at rail locations.

LIMITATIONS

A high proportion of missing data means that the findings need to be interpreted with caution. It also restricted the multivariate analysis to those categories of information for which sufficient information was available.

CONCLUSION

The characteristics and circumstances of suicide deaths on the railways are complex and multifaceted. The typology identified in this study may help to target preventative strategies prior to the incident as well as at different location types.

Self-harm among inmates of the Berlin prison system

Introduction

Self-harming behavior in prisoners is a prevalent phenomenon, with international studies estimating a 4% prevalence rate. However, studies on self-injurious behavior in the German prison system are currently lacking. Therefore, our study aims to conduct an initial assessment.

Methods

The Criminological Service for the Berlin Prison System distributed questionnaires on incidents of self-harm to all Berlin prisons, except for juvenile detention centers. The questionnaires were supplemented with medical data, such as psychiatric diagnoses and medication.

Results

62 questionnaires were returned, which could be attributed to 52 inmates. Compared to the average population in the Berlin prison system, the study sample exhibited variations in age, gender distribution and nationality. 94% of the inmates received a psychiatric diagnosis. Two-thirds of the male inmates had substance use disorders, while 83% of the female inmates had emotionally unstable personality resp. borderline disorders. Prior to self-harm, 87% of the inmates were administered psychiatric medication.

Discussion

Our study found similarities between the study population and international studies in the distribution of certain characteristics. We assume that many of the postulated risk factors can also apply to Berlin prisoners. However, the study is limited by the small number of cases and the absence of a control group.

Hospital-presenting self-harm among older adults living in Ireland: a 13-year trend analysis from the National Self-Harm Registry Ireland

OBJECTIVES

To examine trends in rates of self-harm among emergency department (ED) presenting older adults in Ireland over a 13-year period.

DESIGN

Population-based study using data from the National Self-Harm Registry Ireland.

SETTING

National hospital EDs.

PARTICIPANTS

Older adults aged 60 years and over presenting with self-harm to hospital EDs in Ireland between January 1, 2007 and December 31, 2019.

MEASUREMENTS

ED self-harm presentations.

RESULTS

Between 2007 and 2019, there were 6931 presentations of self-harm in older adults. The average annual self-harm rate was 57.8 per 100,000 among older adults aged 60 years and over. Female rates were 1.1 times higher compared to their male counterparts (61.4 vs 53.9 per 100,000). Throughout the study time frame, females aged 60-69 years had the highest rates (88.1 per 100,000), while females aged 80 years and over had the lowest rates (18.7 per 100,000). Intentional drug overdose was the most commonly used method (75.5%), and alcohol was involved in 30.3% of presentations. Between the austerity and recession years (2007-2012), self-harm presentations were 7% higher compared to 2013-2019 (incidence rate ratio (IRR): 1.07 95% CI 1.02-1.13, p = 0.01).

CONCLUSIONS

Findings indicate that self-harm in older adults remains a concern with approximately 533 presentations per year in Ireland. While in younger age groups, females report higher rates of self-harm, this gender difference was reversed in the oldest age group (80 years and over), with higher rates of self-harm among males. Austerity/recession years (2007-2012) had significantly higher rates of self-harm compared to subsequent years.

Risk and protective factors for self-harm and suicide behaviours among serving and ex-serving personnel of the UK Armed Forces, Canadian Armed Forces, Australian Defence Force and New Zealand Defence Force: A systematic review

BACKGROUND

Self-harm and suicide behaviours are a major public health concern. Several factors are associated with these behaviours among military communities. Identifying these factors may have important implications for policy and clinical services. The aim of this review was to identify the risk and protective factors associated with self-harm and suicide behaviours among serving and ex-serving personnel of the United Kingdom Armed Forces, Canadian Armed Forces, Australian Defence Force and New Zealand Defence Force.

METHODS

A systematic search of seven online databases (PubMed, Web of Science, Embase, Global Health, PsycINFO, PTSDpubs and CINAHL) was conducted alongside cross-referencing, in October 2022. Following an a priori PROSPERO approved protocol (CRD42022348867), papers were independently screened and assessed for quality. Data were synthesised using a narrative approach.

RESULTS

Overall, 28 papers were included: 13 from Canada, 10 from the United Kingdom, five from Australia and none from New Zealand. Identified risk factors included being single/ex-relationship, early service leavers, shorter length of service (but not necessarily early service leavers), junior ranks, exposure to deployment-related traumatic events, physical and mental health diagnoses, and experience of childhood adversity. Protective factors included being married/in a relationship, higher educational attainment, employment, senior ranks, and higher levels of perceived social support.

CONCLUSION

Adequate care and support are a necessity for the military community. Prevention and intervention strategies for self-harm and suicide behaviours may be introduced early and may promote social networks as a key source of support. This review found a paucity of peer-reviewed research within some populations. More peer-reviewed research is needed, particularly among these populations where current work is limited, and regarding modifiable risk and protective factors.

A systematic review of the epidemiology of suicide in Iraq and Kurdistan region

OBJECTIVES

The suicide rate has increased in Iraq in recent years, making it a major public health concern. This systematic review examines the prevalence of suicidal behaviours in the Iraq and Kurdistan region.

MATERIALS AND METHODS

This study adhered to the PRISMA guidelines, conducting searches on PubMed, MEDLINE, Web of Science, and Google Scholar. Out of 153 initially identified publications, only 18 full articles met the inclusion criteria, with 135 articles excluded due to reasons such as eligibility criteria, duplication, predatory publications and lack of relevance and lack of quality data.

RESULTS

The suicide crude rate in Iraq (excluding Kurdistan) rose from 1.09 to 1.31 per 100,000 between 2015 and 2016, while Kurdistan had an estimated rate of 3.83 per 100,000 during the same period. Limited data on reference group sizes and population figures make specific rate calculations challenging. Suicide is more prevalent among women, those aged 15-40, and individuals with mental disorders. Contributing factors include domestic violence, mental health issues, and traditional norms. Urban residents generally have higher suicide rates than rural residents. Common suicide behaviours include self-immolation, hanging, firearms, jumping from heights, and self-poisoning with pesticides.

CONCLUSION

The prevalence of suicide in Iraq, as indicated by this systematic review, requires urgent attention and effective public health initiatives. The interplay of social, economic, cultural, and psychological factors emphasizes the need for comprehensive prevention programs. Additionally, a crucial requirement is the implementation of a standardised method for collecting suicide data to improve epidemiological understanding.

"No Abnormality Detected": A Mixed-Methods Examination of Emergency Department Coding Practices for People in Suicidal Crisis

BACKGROUND

Accurate identification of suicidal crisis presentations to emergency departments (EDs) can lead to timely mental health support, improve patient experience, and support evaluations of suicide prevention initiatives. Poor coding practices within EDs are preventing appropriate patient care. Aims of the study are (1) examine the current suicide-related coding practices, (2) identify the factors that contribute to staff decision-making and patients receiving the incorrect code or no code.

METHOD

A mixed-methods study was conducted. Quantitative data were collated from six EDs across Merseyside and Cheshire, United Kingdom from 2019 to 2021. Attendances were analyzed if they had a presenting complaint, chief complaint, or primary diagnosis code related to suicidal crisis, suicidal ideation, self-harm or suicide attempt. Semi-structured interviews were conducted with staff holding various ED positions (n = 23).

RESULTS

A total of 15,411 suicidal crisis and self-harm presentations were analyzed. Of these, 21.8% were coded as 'depressive disorder' and 3.8% as 'anxiety disorder'. Absence of an appropriate suicidal crisis code resulted in staff coding presentations as 'no abnormality detected' (23.6%) or leaving the code blank (18.4%). The use of other physical injury codes such as 'wound forearm', 'head injury' were common. Qualitative analyses elucidated potential causes of inappropriate coding, such as resource constraints and problems with the recording process.

CONCLUSION

People attending EDs in suicidal crisis were not given a code that represented the chief presentation. Improved ED coding practices related to suicidal crisis could result in considerable benefits for patients and more effective targeting of resources and interventions.

Impact of continuity of care on older adults diagnosed with mental and behavioural disorders at risk of death due to intentional self-harm: a retrospective Korean cohort study

OBJECTIVES

The aim of this study was to evaluate the impact of continuity of care on older adults diagnosed with mental and behavioural disorders who are at risk of death due to intentional self-harm.

STUDY DESIGN

This was a retrospective cohort study.

METHODS

Data from the Korean National Health Insurance Service-Elderly Cohort Database (2002-2013) were used. A total of 53,980 patients who had visited the outpatient clinic three or more times within the year following the initial diagnosis of mental and behavioural disorders were included. A generalised estimating equation model was generated to examine the impact of continuity of care (CoC) on the risk of death due to intentional self-harm among older adults with mental illnesses.

RESULTS

The risk of death due to intentional self-harm was significantly higher in those with poor CoC for mental and behavioural disorders than in those with good CoC. The risk ratio, adjusting for all covariates, was larger for the Usual Provider of Care index (adjusted risk ratio [aRR]: 1.63, 95% confidence interval [CI]: 1.25-2.12) than for the CoC index (aRR: 1.50, 95% CI: 1.18-1.90), indicating a stronger association with the concentration of contact with the most frequently visited provider.

CONCLUSIONS

Poor CoC among Korean older adults diagnosed with mental and behavioural disorders was identified as a significant risk factor for death due to intentional self-harm. The results of this study highlight the need for interventions that can prevent suicidal behaviour in older adults, such as institutionalising the usual providers of mental health care for older adults.

To what extent are psychological variables considered in the study of risk and protective factors for suicidal thoughts and behaviours in individuals with cancer? A systematic review of 70 years of research

Psychological variables substantially shape the risk of suicidal thoughts and behaviours (STBs). However, it is unclear to what extent they are considered in individuals with cancer. We synthesized the quantitative research landscape concerning psychological risk/protective factors of STBs in the (psycho-) oncological context. This pre-registered review (PROSPERO-ID CRD42022331484) systematically searched the databases PubMed/Medline, CINAHL, PsycInfo, Cochrane Library, and Web of Science (as well as the grey literature and preprints). Risk of bias (RoB) was estimated using the ROBINS-I tool. Of 11,159 retrieved records, 319 studies were eligible for inclusion. Of those, 163 (51.1%) had investigated psychological factors (affective: n = 155; social: n = 65; cognitive: n = 63; personality/individual differences: n = 37; life events: n = 6), in a combined 3,561,741 participants. The most common STBs were suicidal ideation (n = 107) or death wishes (n = 20) rather than behaviour (suicide deaths: n = 26; attempts: n = 14). Most studies had a serious RoB. Thus, a large body of research investigated STBs in cancer patients/survivors, but it rarely aligned with the theoretical or clinical developments in suicide research. We propose a conceptual model of STBs in cancer delineating moderation and mediation effects to advance the integration of the fields, and to inform future research and practice.

Possible Mental Health Interventions for Family Members of a Close Relative Who Has Suicidal Thoughts or Committed Suicide: A Pilot Project at a Mental Health Center

Background: Suicides are an actual issue, especially in Lithuania, where, despite significant efforts, the number of suicides remains very high. In cases of suicide, society painfully loses its members, and the relatives of the person who committed suicide, engaged in self-harm, or attempted suicide face many negative experiences. Methods: The purpose of this article is to describe the pilot project applied for 2 years in the Mental Health Center (MHC) in the city of Vilnius, Lithuania, in organizing and providing services to people whose relatives committed suicide or attempted suicide or self-harm. This prevention and early intervention program, organized by an interdisciplinary team at an MHC, appeared appropriate, effective, and well-attended. Program clients could participate anonymously and have the opportunity to choose the time and the right services for themselves from the offered program services package. Results: Providing the possibility for family members to receive flexible mental health services at the primary center increased the attractiveness of the program and reduced stigma. Conclusions: The program results demonstrated the applicability of the implementation of such an initiative as a relevant possibility when providing complex help for the relatives of self-harming and/or suicidal people.

Examining the relationship between adversity and suicidality and self-harm in Irish adolescents from 2020 to 2022

BACKGROUND

Research indicates that there is a strong association between childhood adversity and youth suicide and self-harm. However, there is currently a lack of understanding about the patterns of adversity most frequently experienced by youth across social settings, and whether these typologies differently predict youth engagement in suicide and self-harm. This study examines the dominant patterns of adversity experienced by adolescents across home, peer, and school contexts, and explores the relationship between youth's adversity profiles and their suicide and self-harm outcomes, across a two year period (2020-2022).

METHODS

Secondary analyses were performed on data collected from 10,281 (50 % male) adolescents who participated in the Irish Planet Youth questionnaire in 2020 (n = 5004) or 2022 (n = 5277).

RESULTS

Findings from clustered latent class analyses indicated that there are four dominant profiles of adversity experienced by adolescents. Class 1 (Multiple Adversity) was characterised by a high probability of experiencing adversity across multiple social settings. Class 2 (Parent Adversity) had a strong likelihood of experiencing adversity with parents. Class 3 (Peer Adversity) were likely to experience adversity within the peer/friend domain. Class 4 was characterised by a low probability of experiencing adversity. Findings from logistic regression models with BCH training weights indicated that there were significant differences in self-harm and suicidality across the adversity classes. In comparison to the low adversity group, adolescents in the multiple adversity group were more likely to self-harm and attempt suicide.

LIMITATIONS

These findings are based on cross-sectional data and rely on the use of single-item measurements, which may limit the generalisability of findings.

DISCUSSION

Results indicate that youth who experience adversity across home, peer and school contexts are at the greatest risk of engaging in suicide and self-harm. These findings have important implications for policy and practice, and suggest that youth experiencing adversity across multiple settings should be priority targets for intervention.

Similarities and differences in the prevalence and risk factors of suicidal behavior between caregivers and people with dementia: a systematic review

BACKGROUND

People with dementia and their caregivers are prone to suicidal behaviors due to difficulty adjusting to their initial caregiving role and due to emotional disturbances resulting from deterioration of functioning. The present systematic review (1) explored the prevalence of and risk factors for suicidal behavior and (2) assessed the similarities and differences in the prevalence and risk factors for suicidal behavior between people with dementia and their caregivers.

METHODS

A comprehensive literature search for research articles published between 1950 and 2023 was carried out using major databases, such as Google Scholar, Web of Science, PubMed, Scopus, PsycINFO, EMBASE, the Cochrane Library, and Medline.

RESULTS

A total of 40 research articles were selected for review. A total of 12 research articles revealed that the prevalence of suicidal behavior among caregivers ranged from 4.7% to 26%. However, the risk of suicidal behavior among people with dementia was inconsistent, as only 17 out of 28 selected studies reported the risk of suicidal behavior among people with dementia. The risk factors associated with suicidal behavior among caregivers of people with dementia could be both self-related and care receiver-related factors, whereas risk factors in people with dementia were self-related factors. Notably, greater cognitive decline, which impairs individuals' ability to carry out complex acts and planning, may lower their suicidal risk. Finally, assessment of the risk of bias indicated that 95% of the selected studies had unclear risk.

CONCLUSION

Self-related and care receiver-related factors should be assessed among caregivers of people with dementia to evaluate the risk of suicidal behavior. In addition, we recommend evaluating suicidal risk in people with dementia in the early phase of dementia when cognitive decline is less severe. However, as the majority of the selected studies had unclear risk of bias, future studies with improved methodologies are warranted to confirm our study findings.

Are we Using the Right Evidence to Inform Suicide Prevention in Low- and Middle-Income Countries? An Umbrella Review

OBJECTIVE

Suicide disproportionately affects low- and middle-income countries and evidence regarding prevention approaches developed in high income countries may not be applicable in these settings. We conducted an umbrella review to assess whether the conclusions of suicide prevention systematic reviews accurately reflect the studies contained within those reviews in terms of setting generalizability.

METHODS

We conducted database searches in PubMed/Medline, Embase, PsycInfo, PsychExtra, OVID global health, and LILACS/BECS. We included systematic reviews with the outcome of suicide, including bereavement studies where suicide death was also the exposure.

RESULTS

Out of the 147 reviews assessed, we found that over 80% of systematic reviews on suicide deaths do not provide an accurate summary of review findings with relation to geographic relevance and ultimately generalizability.

CONCLUSION

Systematic reviews are often the resource used by practitioners and policymakers to guide services. Misleading reviews can detrimentally impact suicide prevention efforts in LMICs. We call for systematic reviewers to be responsible when generalizing the findings of their reviews particularly in the abstracts.

Distinct correlation network of clinical characteristics in suicide attempters having adolescent major depressive disorder with non-suicidal self-injury

Suicidal behavior and non-suicidal self-injury (NSSI) are common in adolescent patients with major depressive disorder (MDD). Thus, delineating the unique characteristics of suicide attempters having adolescent MDD with NSSI is important for suicide prediction in the clinical setting. Here, we performed psychological and biochemical assessments of 130 youths having MDD with NSSI. Participants were divided into two groups according to the presence/absence of suicide attempts (SAs). Our results demonstrated that the age of suicide attempters is lower than that of non-attempters in participants having adolescent MDD with NSSI; suicide attempters had higher Barratt Impulsiveness Scale (BIS-11) impulsivity scores and lower serum CRP and cortisol levels than those having MDD with NSSI alone, suggesting levels of cortisol and CRP were inversely correlated with SAs in patients with adolescent MDD with NSSI. Furthermore, multivariate regression analysis revealed that NSSI frequency in the last month and CRP levels were suicidal ideation predictors in adolescent MDD with NSSI, which may indicate that the increased frequency of NSSI behavior is a potential risk factor for suicide. Additionally, we explored the correlation between psychological and blood biochemical indicators to distinguish suicide attempters among participants having adolescent MDD with NSSI and identified a unique correlation network that could serve as a marker for suicide attempters. Our research data further suggested a complex correlation between the psychological and behavioral indicators of impulsivity and anger. Therefore, our study findings may provide clues to identify good clinical warning signs for SA in patients with adolescent MDD with NSSI.

The prevalence and clinical correlates of suicide attempts in patients with bipolar disorder misdiagnosed with major depressive disorder: Results from a national survey in China

BACKGROUND AND AIM

Suicide is nearly always associated with underlying mental disorders. Risk factors for suicide attempts (SAs) in patients with bipolar disorder (BD) misdiagnosed with major depressive disorder (MDD) remain unelucidated. This study was to evaluate the prevalence and clinical risk factors of SAs in Chinese patients with BD misdiagnosed with MDD.

METHODS

A total of 1487 patients with MDD from 13 mental health institutions in China were enrolled. Mini International Neuropsychiatric Interview (MINI) was used to identify patients with BD who are misdiagnosed as MDD. The general sociodemographic and clinical data of the patients were collected and MINI suicide module was used to identify patients with SAs in these misdiagnosed patients.

RESULTS

In China, 20.6% of patients with BD were incorrectly diagnosed as having MDD. Among these misdiagnosed patients, 26.5% had attempted suicide. These patients tended to be older, had a higher number of hospitalizations, and were more likely to experience frequent and seasonal depressive episodes with atypical features, psychotic symptoms, and suicidal thoughts. Frequent depressive episodes and suicidal thoughts during depression were identified as independent risk factors for SAs. Additionally, significant sociodemographic and clinical differences were found between individuals misdiagnosed with MDD in BD and patients with MDD who have attempted suicide.

CONCLUSIONS

This study highlights the importance of accurate diagnosis in individuals with BD and provide valuable insights for the targeted identification and intervention of individuals with BD misdiagnosed as having MDD and those with genuine MDD, particularly in relation to suicidal behavior.
