Adolescents exposed to suicidal behavior of others: prevalence of self-harm and associated psychological, lifestyle, and life event factors

Overlap Between Exposure to Suicidal Behavior and Indirect Interpersonal Violence: Evidence for a More Integrated Approach to Violence Research

This study examines the overlap between indirect exposure to forms of interpersonal violence and suicidal behavior, and the impact of the co-occurrence of these exposures on indicators of depressed mood and substance use among adolescents. Participants were a national sample of 3,917 youth aged 14-15 years, recruited online between June 2018 and March 2020, including an oversample of sexual and gender minority youth. Eight in ten (81.3%) youth reported exposure to indirect interpersonal violence and/or suicidal behavior in their lifetimes: 39.5% reported only interpersonal violence exposure, 5.9% only suicidal behavior exposure, and 35.9% reported both. Youth who reported exposure to interpersonal violence were almost three times more likely (adjusted odds ratio [OR] = 2.78, p < .001) to also report suicidal behavior exposure. Compared with youth having no indirect violence exposure, those with only interpersonal violence exposure were 2.25 times more likely (p < .001), those with only exposure to suicidal behavior 2.93 times more likely (p < .001), and those with both were 5.63 times more likely to report recent depressed mood. The unadjusted odds of any substance use was significantly elevated for each type of indirect violence exposure, with the highest odds seen among youth with dual interpersonal violence and suicide exposure (OR = 4.87, p < .001). For both outcomes, significant findings remained but were attenuated after adjusting for demographic characteristics, non-victimization adversity exposure, and cumulative direct victimization. Findings suggest that the combination of exposure to interpersonal violence and suicidal behavior appears to be particularly impactful. Results highlight that assessment of trauma exposure among adolescents needs to be more comprehensive and include not only direct and indirect interpersonal violence, but also knowledge of other people's suicidal thoughts and behaviors.

Using a television programme as a tool to increase perceived awareness of mental health and well-being - findings from 'Our Mental Health' survey

BACKGROUND

International research shows that media can increase knowledge, raise public awareness and reduce stigma relating to mental health.

METHODS

Following the broadcast of a documentary on national television featuring interviews with young people who had experienced mental health difficulties and suicidal behaviour, an anonymous online survey, aimed at examining public perceptions of the impact of a television documentary, was conducted, using a mixed methods approach.

RESULTS

2311 people completed the survey. Of those who watched the documentary and answered the closed questions (n = 854), 94% stated that the documentary will positively impact young people's mental health and well-being. The majority (91%) stated that the documentary will encourage young people to talk to someone if experiencing difficulties and 87% indicated it will help to reduce stigma associated with mental health. Viewers had a 5% higher level of intention to seek help than non-viewers. Participants indicated that the identifiable personal stories and discourse around stigma and shame, and the increased understanding and awareness gained, had the most profound impact on them.

CONCLUSIONS

These findings indicate that a documentary addressing mental health and suicidal behaviour, which incorporates real life identifiable stories of resilience and recovery, has the potential to impact positively on emotional well-being and general mood, to reduce stigma related to mental health and to encourage help-seeking behaviour. Documentaries including these concepts, with a public mental health focus and a consistent message, incorporating pre- and post-evaluations, and customisation for target audiences in compliance with current media recommendations, should be considered.

Exposure to Suicidal Behavior and Social Support Among Sexual- and Gender-Minority Youth

OBJECTIVES

In this study, we examine reports of exposure to suicidal behavior by youth sexual and gender identity. We explore how exposure is related to depressed mood in the context of high social support while accounting for cumulative adversity.

METHODS

Data from a large national sample of youth aged 14 to 15 years in the United States (N = 3979) were collected online in 2018-2019.

RESULTS

Sexual- and gender-minority youth were more likely to know someone close to them who attempted suicide, relative to cisgender heterosexual youth. Cisgender heterosexual youth were buffered from recent depressed mood when they endorsed having high social support in the context of exposure to suicidal behavior; less social support did not provide such a buffer. For cisgender sexual-minority male and female youth, exposure to suicidal behavior was related to recent depressed mood regardless of the level of social support. For gender-minority youth assigned female at birth, the combination of exposure and high social support was significantly associated with elevated depressed mood. Cumulative adversity accounted for some but not all of these relationships, indicating the influential role of exposure to suicidal behavior on depressed mood for some youth.

CONCLUSIONS

These findings illustrate the complexities of social support and raise questions about its potential to magnify stress rather than serve as a buffer for some youth. Although findings need to be replicated, suicide prevention efforts should carefully consider how to promote resilience among these suicide-exposed sexual- and gender-minority youth who may themselves be at risk for suicidal ideation and behavior.

Interventions for self-harm in children and adolescents

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury regardless of degree of suicidal intent or other types of motivation) is a growing problem in most countries, often repeated, and associated with suicide. Evidence assessing the effectiveness of interventions in the treatment of SH in children and adolescents is lacking, especially when compared with the evidence for psychosocial interventions in adults. This review therefore updates a previous Cochrane Review (last published in 2015) on the role of interventions for SH in children and adolescents.

OBJECTIVES

To assess the effects of psychosocial interventions or pharmacological agents or natural products for SH compared to comparison types of care (e.g. treatment-as-usual, routine psychiatric care, enhanced usual care, active comparator, placebo, alternative pharmacological treatment, or a combination of these) for children and adolescents (up to 18 years of age) who engage in SH.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Specialized Register, the Cochrane Library (Central Register of Controlled Trials [CENTRAL] and Cochrane Database of Systematic Reviews [CDSR]), together with MEDLINE, Ovid Embase, and PsycINFO (to 4 July 2020).

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing specific psychosocial interventions or pharmacological agents or natural products with treatment-as-usual (TAU), routine psychiatric care, enhanced usual care (EUC), active comparator, placebo, alternative pharmacological treatment, or a combination of these, in children and adolescents with a recent (within six months of trial entry) episode of SH resulting in presentation to hospital or clinical services. The primary outcome was the occurrence of a repeated episode of SH over a maximum follow-up period of two years. Secondary outcomes included treatment adherence, depression, hopelessness, general functioning, social functioning, suicidal ideation, and suicide.

DATA COLLECTION AND ANALYSIS

We independently selected trials, extracted data, and appraised trial quality. For binary outcomes, we calculated odds ratios (ORs) and their 95% confidence internals (CIs). For continuous outcomes, we calculated the mean difference (MD) or standardised mean difference (SMD) and 95% CIs. The overall quality of evidence for the primary outcome (i.e. repetition of SH at post-intervention) was appraised for each intervention using the GRADE approach.

MAIN RESULTS

We included data from 17 trials with a total of 2280 participants. Participants in these trials were predominately female (87.6%) with a mean age of 14.7 years (standard deviation (SD) 1.5 years). The trials included in this review investigated the effectiveness of various forms of psychosocial interventions. None of the included trials evaluated the effectiveness of pharmacological agents in this clinical population. There was a lower rate of SH repetition for DBT-A (30%) as compared to TAU, EUC, or alternative psychotherapy (43%) on repetition of SH at post-intervention in four trials (OR 0.46, 95% CI 0.26 to 0.82; N = 270; k = 4; high-certainty evidence). There may be no evidence of a difference for individual cognitive behavioural therapy (CBT)-based psychotherapy and TAU for repetition of SH at post-intervention (OR 0.93, 95% CI 0.12 to 7.24; N = 51; k = 2; low-certainty evidence). We are uncertain whether mentalisation based therapy for adolescents (MBT-A) reduces repetition of SH at post-intervention as compared to TAU (OR 0.70, 95% CI 0.06 to 8.46; N = 85; k = 2; very low-certainty evidence). Heterogeneity for this outcome was substantial ( I² = 68%). There is probably no evidence of a difference between family therapy and either TAU or EUC on repetition of SH at post-intervention (OR 1.00, 95% CI 0.49 to 2.07; N = 191; k = 2; moderate-certainty evidence). However, there was no evidence of a difference for compliance enhancement approaches on repetition of SH by the six-month follow-up assessment, for group-based psychotherapy at the six- or 12-month follow-up assessments, for a remote contact intervention (emergency cards) at the 12-month assessment, or for therapeutic assessment at the 12- or 24-month follow-up assessments.

AUTHORS' CONCLUSIONS

Given the moderate or very low quality of the available evidence, and the small number of trials identified, there is only uncertain evidence regarding a number of psychosocial interventions in children and adolescents who engage in SH. Further evaluation of DBT-A is warranted. Given the evidence for its benefit in adults who engage in SH, individual CBT-based psychotherapy should also be further developed and evaluated in children and adolescents.

Risk Assessment and Crisis Intervention for Youth in a Time of Telehealth

For the last decade, there has been growing concern regarding the rising rates of youth engagement in self-injury and suicide. The worldwide outbreak of the coronavirus disease 2019 (COVID-19) has elevated these concerns due to increased risk factors pertaining to social, family, economic, and health stressors, in addition to changes to typical routines and support systems. Unfortunately, there are many barriers to at-risk youth being able to access evidence-based mental health services including cost, lack of trained providers, transportation issues, and physical distancing due to the pandemic. Providing school-based prevention and intervention programs that promote social, emotional, and behavioral well-being helps to address many of these barriers. This article highlights important considerations to providing these services in a school-based telehealth modality. Symptom clusters that put youth at risk of harm to self are described. Best practice therapeutic modalities that can be disseminated in a school-based telehealth modality, such as cognitive behavior therapy, dialectical behavior therapy, and mindfulness-based approaches, are reviewed. Although there is growing empirical literature for these school-based prevention and intervention approaches, additional research is needed to determine how to best support at-risk youth remotely.

Exposure to and experience of self-harm and self-harm related content: An exploratory network analysis

Exposure to the self-harm behaviour of others plays a role in individuals' own self-harm thoughts and behaviours, but there has been little consideration of the broader range of mediums through which exposure to self-harm related content may occur. N = 477 participants completed an online study, including questions regarding lifetime history of self-harm thoughts and behaviours and the frequency with which they had been exposed to self-harm via various mediums. Gaussian Markov random field network models were estimated using graphical LASSO and extended Bayesian information criterion. Bootstrapping revealed that exposure mediums with a direct connection to self-harm thoughts and behaviours were the internet (rrp = .34, 95% CI [.26, .42]) and in-passing 'miscellaneous' exposure (rrp = .14, 95% CI [.00, .23]). However, stability of the network centrality was low (expected influence stability = 0.52). The node with the greatest increase in expected influence within the network was miscellaneous "in-passing" exposure. In-passing exposure is an understudied exposure medium. Our results may suggest new types of exposure mediums for future research. Data were cross-sectional, so temporal relationships between exposure and behaviour could not be determined. Low stability of the networks suggests that future similar studies would benefit from larger sample sizes.

A Theory-Based Longitudinal Investigation Examining Predictors of Self-Harm in Adolescents With and Without Bereavement Experiences

BACKGROUND

Research has demonstrated that exposure to suicide can lead to increased vulnerability for self-harm or suicide. As a result, ideation-to-action models of suicide (e.g., the Integrated Motivational-Volitional Model of Suicide; IMV) recognise exposure as a significant risk factor which may be implicated in the translation of thoughts into actions. However, few studies have tested this theoretical link explicitly within an adolescent population, and examined how it compares to other types of bereavements.

METHODS

A 6-month prospective questionnaire study was conducted with 185 Scottish adolescents aged 11-17 (113 adolescents also completed the questionnaire at follow-up). The questionnaire included measures on experiences with bereavement and lifetime engagement in self-harm, as well as measures of defeat, entrapment, social support, coping, and other psychological variables.

RESULTS

At baseline, 12% of young people reported exposure to a suicide death, and 61% to a non-suicide death. In addition, 21% of pupils reported ever engaging in self-harm, while 23% had experienced self-harm ideation without engaging in it. Cross-sectional multivariate logistic regressions showed that family social support, glorifying/normalising beliefs about suicide, and family self-harm were significantly associated with self-harm group membership (control, ideation, or enactment groups). At follow-up, 10% of pupils reported exposure to a suicide death and 16% to a non-suicide death for the first time. A total of 26% of the sample reported self-harm at T2 (11% of participants for the first time), and 24% reported self-harm ideation without engaging in it. Multivariate analyses found that self-harm ideation and family self-harm at baseline were the only variables to predict self-harm group membership prospectively, in the expected directions. Bereavement experiences, whether by suicide or non-suicide, did not predict self-harm group status at baseline nor at follow-up.

CONCLUSIONS

This study provides support for the validity of a theoretical model of suicide, even though predictive ability over the 6-months period was limited. Although difficulties with recruitment may have limited the statistical power, this study provides insight into the prevalence and experiences of suicide bereavement among adolescents and the factors related to the onset and maintenance of self-harm.

Understanding the Needs of Young People Who Engage in Self-Harm: A Qualitative Investigation

Self-harm is common and associated with adverse outcomes. Research about the risk factors for self-harm has informed the field with regard to clinical interventions that should be delivered for young people who engage in self-harm. Missing is an in-depth understanding of what the triggers of an urge to self-harm might be, including in young people being treated with a clinical intervention. Therefore, there is little knowledge about what techniques young people find helpful to deal with urges to self-harm when they occur. This qualitative study engaged seven young people with lived experience of self-harm in semi-structured interviews about the immediate triggers of the urge to self-harm, and helpful strategies to manage this urge. Thematic analysis using a general inductive approach revealed distressing emotions and a sense of isolation as key themes, with other triggers associated with their induction. Highlighted was the wide range of situations and emotions that can be triggering, such that a further key theme was the idiosyncratic nature of the self-help strategies young people found helpful. Interventions that are developed to support young people who self-harm must address this complexity and findings highlight the need for young people to maintain some autonomy and control while being supported to connect with others for support. This research adds to the literature on self-help strategies to support young people in moments when they are experiencing distressing emotions, feel isolated, and have an urge to self-harm providing important insight to the prevention and intervention for self-harm among young people.

A qualitative systematic review of experiences and perceptions of youth suicide

Background

Suicide remains a global issue with over 800,000 people dying from suicide every year. Youth suicide is especially serious due to the years of life lost when a young person takes their own life. Social interactions, perceived support, genetic predisposition and mental illnesses are factors associated with suicide ideation.

Objectives

To review and synthesize qualitative studies that explored the experiences and perceptions of suicide in people 25 years old and younger.

Design

Qualitative systematic review.

Data sources

PubMed, PsycINFO, Scopus and CINAHL were searched alongside hand-searching reference lists up to October 2018.

Methods

Methodological quality was assessed using the qualitative Critical Appraisal Skills Programme checklist. The 27 studies included in the review centered around youth suicide and included interviews with young people and members of the wider community. Thematic synthesis focused on factors leading to suicide attempts, elements important to recovery, beliefs within the community, and treatment/prevention strategies.

Results

Thematic analysis of the articles revealed four categories: i) triggers and risks leading to suicidality; ii) factors involved in recovery; iii) need for institutional treatment/prevention strategies; and iv) beliefs about suicide at a community level. The first category was further subdivided into: i) behaviours; ii) feelings/emotions; iii) family influences; iv) peer influences; and v) other. The second category was split into: i) interpersonal; ii) cultural; and iii) individual influences, while the third category was divided into i) education; and ii) treatment.

Conclusion

Youth suicide is a complex issue with many causes and risks factors which interact with one another. For successful treatment and prevention, procedural reform is needed, along with a shift in societal attitudes toward emotional expression and suicide.

Mediating and moderating variables in the prediction of self-harm in young people: A systematic review of prospective longitudinal studies

BACKGROUND

Self-harm is widespread amongst young people. A growing body of research has explored factors that predict self-harm in young people, however, a systematic review of mediators and moderators of those factors has not yet been offered. This review aims to fill this gap by synthesising research about mediators and moderators of factors that prospectively predict self-harm in young people.

METHOD

A systematic review of research trials published up until 2018 was undertaken. Electronic databases Scopus (Elsevier), CINAHL, PsychINFO (EBSCO) and Medline were searched. Included studies utilised prospective longitudinal designs with participants aged 25 years or younger and self-harm outcome measures with published or reported psychometric properties. The aim of the review was to identify mediators and moderators of factors that predict self-harm in young people.

RESULTS

Of the 25 studies that met inclusion criteria, 22 reported at least one positive finding of a mediator or moderator. Specifically, 15 significant mediators and 20 significant moderators were identified in relation to a broad range of predictors of self-harm. Predictors were classified as adverse childhood experiences and parenting factors, psychological and psychiatric factors, social factors and intrapersonal factors. A number of potentially modifiable mediators and moderators were identified including interpersonal difficulties, impulsivity, self-esteem and self-compassion. Gender was the most commonly reported moderator.

LIMITATIONS

Included studies were assessed as limited by the heterogeneity of the mediators and moderators assessed, and by methodological factors including study durations, population characteristics, and the definition and assessment of self-harm. In addition, replication research was limited. Therefore it was difficult to integrate results and draw firm conclusions.

CONCLUSIONS

This review allowed us to explore diverse relationships between factors predictive of self-harm in young people and to identify a number of potentially modifiable mediators and moderators. Our findings have important implications for future research and treatment efforts as the identification of mediators and moderators is demonstrated to assist in identifying high risk individuals as well informing potential targets for treatment.

Suicidal behaviours among Chinese adolescents exposed to suicide attempt or death

AIMS

Suicidal behaviours in adolescents are prevalent and multifactorial. This study was conducted to examine the associations between exposure to suicide attempt (ESA) or suicide death (ESD) and suicidal behaviours in a large sample of Chinese adolescents.

METHODS

Participants included for the analysis were 11 831 adolescent students who participated in the baseline survey of the Shandong Adolescent Behavior and Health Cohort (SABHC). Participants were sampled from five middle and three high schools in three counties of Shandong province, China. A self-administered structured questionnaire was used to collect data on demographics, behavioural and emotional problems, family environment, suicidal behaviours (suicidal thought, plan and attempt), and history of ESA or death of a family member, relative, friend or close acquaintance. Based on the sources of exposure, the participants were divided into four groups: non-exposure, exposure from relatives only, exposure from friends/close acquaintances only (EFO) and exposure from both relatives and friends (ERF). Logistic regressions were used to examine the associations between ESA or ESD and suicidal behaviours.

RESULTS

Mean age of the participants was 14.97 ± 1.46 years and 50.9% were boys. Of the participants, 9.4% reported having ESA, and 6.6% reported having ESD. The prevalence rates of suicidal behaviours were significantly higher in adolescents who had been exposed to suicide attempt or death than those who had not. Multivariate logistic regressions showed that ESA and ESD were both significantly associated with increased risks of suicidal thought (ESA: OR = 1.96, 95% CI = 1.66-2.31; ESD: OR = 1.59, 95% CI = 1.31-1.94), plan (ESA: OR = 2.37, 95% CI = 1.84-3.05; ESD: OR = 1.62, 95% CI = 1.18-2.23) and attempt (ESA: OR = 2.73, 95% CI = 1.92-3.89; ESD: OR = 1.82, 95% CI = 1.18-2.82), respectively. When participants were exposed to suicide attempt, ERF and EFO groups had significantly higher risks of suicidal thought (ERF: OR = 2.61, 95% CI = 1.28-1.64; EFO: OR = 1.96, 95% CI = 1.64-2.36), plan (ERF: OR = 3.72, 95% CI = 2.04-6.78; EFO: OR = 2.31, 95% CI = 1.74-3.01) and attempt (ERF: OR = 4.83, 95% CI = 2.30-10.17; EFO: OR = 2.57, 95% CI = 1.73-3.81), respectively.

CONCLUSIONS

ESA or ESD was associated with increased risks of suicidal behaviours in adolescents. Exposure to suicidal behaviours of relatives and friends/close acquaintances appeared to have different influence on adolescent suicidal behaviours. Further research is warranted to examine the biological and psychosocial mechanisms between suicidal exposure and subsequent suicidal behaviours in adolescents.

Understanding death, suicide and self-injury among adherents of the emo youth subculture: A qualitative study

Emo youth subculture bases its subcultural identification mostly on symbols of death, dying, suicide, and other kinds of morbid content. The main goal of the present study was to explore attitudes toward suicidal behavior and self-injury in emo adolescents. Semistructured in-depth qualitative interviews were conducted with 14 emo adherents, accompanied by the analysis of emo Web discussion forums. Participants reported attitudes including high acceptance for suicidal behavior and self-injury. The identification with the emo youth subculture is considered to be a factor strengthening vulnerability towards risky behaviors.

Exposure to suicide behaviour and individual risk of self-harm: Findings from a nationally representative New Zealand high school survey

PURPOSE

To examine whether there is an association between students self-reported suicide attempts and non-suicidal self-injury and exposure to suicidal behaviour among friends, family members or within school communities.

METHODS

A cross-sectional analysis of a nationally representative health and well-being survey of 8500 New Zealand high school students conducted from March through November 2012. Students' self-reported suicide attempts and repeated non-suicidal self-injury was examined in relation to student reports of self-harming behaviour among friends and family as well as data from school administrators of completed suicides within the school community.

RESULTS

Almost 1 in 20 (4.5%) students reported a suicide attempt in the last 12 months and 7.9% reported repeated non-suicidal self-injury in the last 12 months. The risk of both suicide attempts and repeated non-suicidal self-injury was highest among females, students from homes with economic deprivation and among students reporting an episode of low mood in the previous 12 months. Students exposed to suicide attempts or completed suicide among friends and/or family members were at increased risk of reporting attempted suicide and repeated non-suicidal self-injury in the last year. There was no association between completed suicide in school community and students self-reported suicide attempts or repeated non-suicidal self-injury.

CONCLUSIONS

Low mood and exposure to suicide attempts of friends and family members are associated with suicide attempts and repeated non-suicidal self-injury in New Zealand high school students. This research highlights importance of supporting adolescents with low mood and exposed to suicide of friends and family.

Mental Health Symptomatology and Exposure to Non-Fatal Suicidal Behavior: Factors That Predict Vulnerability and Resilience Among College Students

Despite efforts to identify risk factors following exposure to completed suicide, research has paid less attention to the associations between exposure to non-fatal suicide behavior (NFSB) and mental health symptomatology-factors that may underlie one's susceptibility to future suicidal thoughts and behaviors. This study examined differences in mental health symptomatology among 192 college students exposed to NFSB and 202 exposed to general stressors. Results indicated that students exposed to NFSB had significantly higher levels of depression and anxiety compared to those exposed to a variety of other stressors but not NFSB. Furthermore, among those exposed, a number of risk and protective factors emerged in relation to psychological sequelae, such as emotional stability, social support, and the quality of the relationship between the exposed and suicidal individual. These findings highlight the importance of enhancing provisions of support for those exposed to NFSB.

Is Exposure to Suicide Beyond Kin Associated with Risk for Suicidal Behavior? A Systematic Review of the Evidence

Suicide bereavement and postvention literature often espouses risk for subsequent suicidal behavior among those previously exposed to a suicide death. Most often risk is discussed in relation to kin; however, many more individuals are exposed to suicide, and the impact of this exposure is important to understand in relation to targeting postvention. This review examined the research literature (1990-2014) to determine the evidence base for risk among those exposed to suicide. The findings demonstrate that risk of suicidal behaviors among those exposed to the suicide is significantly higher than those unexposed. These results are discussed within the context of current research in the field of postvention, and suggestions for future research are suggested.

Premature Death Among Primary Care Patients With a History of Self-Harm

PURPOSE

Self-harm is a public health problem that requires a better understanding of mortality risk. We undertook a study to examine premature mortality in a nationally representative cohort of primary care patients who had harmed themselves.

METHODS

During 2001-2013, a total of 385 general practices in England contributed data to the Clinical Practice Research Datalink with linkage to Office for National Statistics mortality records. We identified 30,017 persons aged 15 to 64 years with a recorded episode of self-harm. We estimated the relative risks of all-cause and cause-specific natural and unnatural mortality using a comparison cohort of 600,258 individuals matched on age, sex, and general practice.

RESULTS

We found an elevated risk of dying prematurely from any cause among the self-harm cohort, especially in the first year of follow-up (adjusted hazard ratio for that year, 3.6; 95% CI, 3.1-4.2). In particular, suicide risk was especially high during the first year (adjusted hazard ratio, 54.4; 95% CI, 34.3-86.3); although it declined sharply, it remained much higher than that in the comparison cohort. Large elevations of risk throughout the follow-up period were also observed for accidental, alcohol-related, and drug poisoning deaths. At 10 years of follow-up, cumulative incidence values were 6.5% (95% CI, 6.0%-7.1%) for all-cause mortality and 1.3% (95% CI, 1.2%-1.5%) for suicide.

CONCLUSIONS

Primary care patients who have harmed themselves are at greatly increased risk of dying prematurely by natural and unnatural causes, and especially within a year of a first episode. These individuals visit clinicians at a relatively high frequency, which presents a clear opportunity for preventive action. Primary care patients with myriad comorbidities, including self-harming behavior, mental disorder, addictions, and physical illnesses, will require concerted, multipronged, multidisciplinary collaborative care approaches.

The Associations Between Children's and Adolescents' Suicidal and Self-Harming Behaviors, and Related Behaviors Within Their Social Networks: A Systematic Review

Social influences-including the suicidal and self-harming behaviors of others-have been highlighted as a risk factor for suicidal and self-harming behavior in young people, but synthesis of the evidence is lacking. A systematic review of 86 relevant papers was conducted. Considerable published evidence was obtained for positive associations between young people's suicidal and self-harming behavior and that of people they know, with those reporting knowing people who had engaged in suicidal or self-harming behaviors more likely to report engaging in similar behaviors themselves. Findings are discussed in relation to a number of methodological and measurement issues-including the role of normative perceptions-and implications for the prevention of suicidal and self-harming behavior are considered.

Interventions for self-harm in children and adolescents

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

OBJECTIVES

To identify all randomised controlled trials of psychosocial interventions, pharmacological agents, or natural products for SH in children and adolescents, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., treatment as usual (TAU), placebo, or alternative pharmacological treatment) for children and adolescents who SH.

SEARCH METHODS

For this update the Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (30 January 2015).

SELECTION CRITERIA

We included randomised controlled trials comparing psychosocial or pharmacological treatments with treatment as usual, alternative treatments, or placebo or alternative pharmacological treatment in children and adolescents (up to 18 years of age) with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected trials, extracted data, and appraised study quality, with consensus. For binary outcomes, we calculated odds ratios (OR) and their 95% confidence intervals (CI). For continuous outcomes measured using the same scale we calculated the mean difference (MD) and 95% CI; for those measured using different scales we calculated the standard mean difference (SMD) and 95% CI. Meta-analysis was only possible for two interventions: dialectical behaviour therapy for adolescents and group-based psychotherapy. For these analyses, we pooled data using a random-effects model.

MAIN RESULTS

We included 11 trials, with a total of 1,126 participants. The majority of participants were female (mean = 80.6% in 10 trials reporting gender). All trials were of psychosocial interventions; there were none of pharmacological treatments. With the exception of dialectical behaviour therapy for adolescents (DBT-A) and group-based therapy, assessments of specific interventions were based on single trials. We downgraded the quality of evidence owing to risk of bias or imprecision for many outcomes.Therapeutic assessment appeared to increase adherence with subsequent treatment compared with TAU (i.e., standard assessment; n = 70; k = 1; OR = 5.12, 95% CI 1.70 to 15.39), but this had no apparent impact on repetition of SH at either 12 (n = 69; k = 1; OR 0.75, 95% CI 0.18 to 3.06; GRADE: low quality) or 24 months (n = 69; k = 1; OR = 0.69, 05% CI 0.23 to 2.14; GRADE: low quality evidence). These results are based on a single cluster randomised trial, which may overestimate the effectiveness of the intervention.For patients with multiple episodes of SH or emerging personality problems, mentalisation therapy was associated with fewer adolescents scoring above the cut-off for repetition of SH based on the Risk-Taking and Self-Harm Inventory 12 months post-intervention (n = 71; k = 1; OR = 0.26, 95% CI 0.09 to 0.78; GRADE: moderate quality). DBT-A was not associated with a reduction in the proportion of adolescents repeating SH when compared to either TAU or enhanced usual care (n = 104; k = 2; OR 0.72, 95% CI 0.12 to 4.40; GRADE: low quality). In the latter trial, however, the authors reported a significantly greater reduction over time in frequency of repeated SH in adolescents in the DBT condition, in whom there were also significantly greater reductions in depression, hopelessness, and suicidal ideation.We found no significant treatment effects for group-based therapy on repetition of SH for individuals with multiple episodes of SH at either the six (n = 430; k = 2; OR 1.72, 95% CI 0.56 to 5.24; GRADE: low quality) or 12 month (n = 490; k = 3; OR 0.80, 95% CI 0.22 to 2.97; GRADE: low quality) assessments, although considerable heterogeneity was associated with both (I(2) = 65% and 77% respectively). We also found no significant differences between the following treatments and TAU in terms of reduced repetition of SH: compliance enhancement (three month follow-up assessment: n = 63; k = 1; OR = 0.67, 95% CI 0.15 to 3.08; GRADE: very low quality), CBT-based psychotherapy (six month follow-up assessment: n = 39; k = 1; OR = 1.88, 95% CI 0.30 to 11.73; GRADE: very low quality), home-based family intervention (six month follow-up assessment: n = 149; k = 1; OR = 1.02, 95% CI 0.41 to 2.51; GRADE: low quality), and provision of an emergency card (12 month follow-up assessment: n = 105, k = 1; OR = 0.50, 95% CI 0.12 to 2.04; GRADE: very low quality). No data on adverse effects, other than the planned outcomes relating to suicidal behaviour, were reported.

AUTHORS' CONCLUSIONS

There are relatively few trials of interventions for children and adolescents who have engaged in SH, and only single trials contributed to all but two comparisons in this review. The quality of evidence according to GRADE criteria was mostly very low. There is little support for the effectiveness of group-based psychotherapy for adolescents with multiple episodes of SH based on the results of three trials, the evidence from which was of very low quality according to GRADE criteria. Results for therapeutic assessment, mentalisation, and dialectical behaviour therapy indicated that these approaches warrant further evaluation. Despite the scale of the problem of SH in children and adolescents there is a paucity of evidence of effective interventions. Further large-scale trials, with a range of outcome measures including adverse events, and investigation of therapeutic mechanisms underpinning these interventions, are required. It is increasingly apparent that development of new interventions should be done in collaboration with patients to ensure that these are likely to meet their needs. Use of an agreed set of outcome measures would assist evaluation and both comparison and meta-analysis of trials.

Global trends in teenage suicide: 2003-2014

The object of this article is to review the past decade of research on teenage suicide, with a particular emphasis on epidemiologic trends by age, gender and indigenous ethnicity. As such, a review of research literature from 2003 to 2014 was conducted via a comprehensive search of relevant psychological and medical databases. Wide gaps in our knowledge base exist concerning the true extent of teenage suicide due to lack of data, particularly in developing countries, resulting in a Western bias. The gender paradox of elevated suicidality in females with higher completed suicide rates in males is observed in teenage populations worldwide, with the notable exceptions of China and India. Native and indigenous ethnic minority teens are at significantly increased risk of suicide in comparison to general population peers. Often those with the highest need for mental health care (such as the suicidal adolescent) have least access to therapeutic support.Globally, suicide in teenagers remains a major public health concern. Further focused research concerning completed suicides of youth below the age of 18 is required across countries and cultures to understand more about risk as children progress through adolescence. Gender and ethnic variations in suicidality are embedded within cultural, historical, psychological, relational and socio-economic domains. Worldwide, the absence of child/adolescent-specific mental health policies may delay the development of care and suicide prevention. Overall, it is vital that clinicians adopt a holistic approach that incorporates an awareness of age and gender influences, and that cultural competency informs tailored and evaluated intervention programmes.
