Suicide Prevention

What is "safety"?: Lethal means counseling as a cross-cultural communication

U.S. suicide rates have risen every year over the past two decades with self-directed firearm use as the method accounting for the highest proportion of deaths. This pattern is particularly pronounced among veterans and members of the U.S. Armed Forces. The numerical burden of firearm-related suicide accompanied by characteristics of self-directed firearm injury have motivated the development of lethal means safety initiatives focused on firearms. Simultaneously, research has sought to characterize patterns of firearm ownership and use among veterans as well as optimal strategies for clinicians to deliver suicide prevention messages to firearm owners. Increasingly, findings from research have been understood as cultural factors that warrant greater attention to improve the quality of lethal means counseling. Here, we review and interpret selected research on cultural aspects of firearm ownership and suggest that cultural differences between health care practitioners and firearm owners may result in health care practitioners delivering clinical interventions that are broadly divergent from perspectives within the cultural frameworks of firearm owners. We follow by organizing these cultural factors into existing frameworks of cultural competency training as a basis for developing curriculum for health care practitioners to improve clinical care.

Community Based Support for People at Risk for Suicide and Those Who Care for them - Areas for Improvement

To systematically review the quality of evidence regarding the effectiveness of supports for people affected by suicide. EMBASE, MEDLINE, and PsychINFO were searched for evaluations of community-based supports for people affected by suicide. Outcomes included suicide-related behavior, depression, grief, quality of life, caring ability, and qualitative experiences. Fifteen studies evaluated 15 supports of various modalities. Study quality was generally poor; most studies examined bereaved individuals with mixed findings. Few reduced suicide-related behavior, half improved depression, and grief, while studies of caring ability, quality of life, or qualitative experiences reported positive effects. Supports associated with better outcomes connected peers with similar experiences, were provided over a period of months, and involved veteran rather than novice facilitators. Supports for people affected by suicide may be effective for improving suicide-related behavior, psychological adjustment, quality of life and caregiving, but require further evaluation.

What Works in Youth Suicide Prevention? A Systematic Review and Meta-Analysis

BACKGROUND

Young people require specific attention when it comes to suicide prevention, however efforts need to be based on robust evidence.

METHODS

We conducted a systematic review and meta-analysis of all studies examining the impact of interventions that were specifically designed to reduce suicide-related behavior in young people.

FINDINGS

Ninety-nine studies were identified, of which 52 were conducted in clinical settings, 31 in educational or workplace settings, and 15 in community settings. Around half were randomized controlled trials. Large scale interventions delivered in both clinical and educational settings appear to reduce self-harm and suicidal ideation post-intervention, and to a lesser extent at follow-up. In community settings, multi-faceted, place-based approaches seem to have an impact. Study quality was limited.

INTERPRETATION

Overall whilst the number and range of studies is encouraging, gaps exist. Few studies were conducted in low-middle income countries or with demographic populations known to be at increased risk. Similarly, there was a lack of studies conducted in primary care, universities and workplaces. However, we identified that specific youth suicide-prevention interventions can reduce self-harm and suicidal ideation; these types of intervention need testing in high-quality studies.

Not at Imminent Risk. A Systematic Literature Review

BACKGROUND

Suicide is a pervasive and complex issue that can challenge counselors through the course of their careers. Research and practice focus heavily on crisis management and imminent risk rather than early intervention strategies. Early intervention strategies can assist counselors working with clients who have suicidal ideation, but are not at imminent risk, or with clients whose risk factors identify them as having a stronger trajectory for suicidal ideation.

AIMS

This systematic literature review examines the current literature on working with clients with suicidal ideation who are not at imminent risk, to ascertain the types of information and strategies available to counselors working with this client group.

METHOD

An initial 622 articles were identified for analysis and from these 24 were included in the final review, which was synthesized using a narrative approach.

RESULTS

Results indicate that research into early intervention strategies is extremely limited.

CONCLUSION

It was possible to describe emergent themes and practice guidelines to assist counselors working with clients with suicidal ideation but not at imminent risk.

Effect of phone call versus face-to-face follow-up on recurrent suicide attempts prevention in individuals with a history of multiple suicide attempts

BACKGROUND

To evaluate the efficacy of different ways of communications on prevention of suicidal reattempt, we compared the efficacy of phone call versus face-to-face follow-up in patients with previous attempt.

MATERIALS AND METHODS

In a randomized controlled clinical trial, 55 suicide reattempters who were admitted to the poisoning emergency were divided into phone call (29 patients) and face-to-face (26 patients) groups randomly. They were followed at 8 occasions: 2^nd and 4^th weeks, and the 2^nd, 3^rd, 4^th, 5^th, 6^th, and 8^th months. The suicidal reattempt, suicidal thought, hope, and interest of the patients were assessed on each occasion, and the patients were guided to visit by a therapist, if needed. The findings were analyzed by Mann-Whitney, Chi-square, Cochran, Friedman, and independent t-tests using SPSS 20.

RESULTS

The status of "hope" and "interest" improved in both groups, but it showed more significant difference in the face-to-face group. Suicidal thoughts in both groups decreased over time, and this was more significant in the face-to-face group. However, we did not found any significant difference in the frequency of the suicidal reattempts between two groups.

CONCLUSION

Face-to-face versus phone call follow-up of suicide attempters can significantly alleviate suicidal thoughts and improve hopes and interests.

Effective psychological and psychosocial approaches to reduce repetition of self-harm: a systematic review, meta-analysis and meta-regression

OBJECTIVE

To examine the efficacy of psychological and psychosocial interventions for reductions in repeated self-harm.

DESIGN

We conducted a systematic review, meta-analysis and meta-regression to examine the efficacy of psychological and psychosocial interventions to reduce repeat self-harm in adults. We included a sensitivity analysis of studies with a low risk of bias for the meta-analysis. For the meta-regression, we examined whether the type, intensity (primary analyses) and other components of intervention or methodology (secondary analyses) modified the overall intervention effect.

DATA SOURCES

A comprehensive search of MEDLINE, PsycInfo and EMBASE (from 1999 to June 2016) was performed.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised controlled trials of psychological and psychosocial interventions for adult self-harm patients.

RESULTS

Forty-five trials were included with data available from 36 (7354 participants) for the primary analysis. Meta-analysis showed a significant benefit of all psychological and psychosocial interventions combined (risk ratio 0.84; 95% CI 0.74 to 0.96; number needed to treat=33); however, sensitivity analyses showed that this benefit was non-significant when restricted to a limited number of high-quality studies. Meta-regression showed that the type of intervention did not modify the treatment effects.

CONCLUSIONS

Consideration of a psychological or psychosocial intervention over and above treatment as usual is worthwhile; with the public health benefits of ensuring that this practice is widely adopted potentially worth the investment. However, the specific type and nature of the intervention that should be delivered is not yet clear. Cognitive-behavioural therapy or interventions with an interpersonal focus and targeted on the precipitants to self-harm may be the best candidates on the current evidence. Further research is required.

Social media and suicide prevention: a systematic review

AIM

Social media platforms are commonly used for the expression of suicidal thoughts and feelings, particularly by young people. Despite this, little is known about the ways in which social media can be used for suicide prevention. The aim of this study was to conduct a systematic review to identify current evidence pertaining to the ways in which social media are currently used as a tool for suicide prevention.

METHODS

Medline, PsycInfo, Embase, CINHAL and the Cochrane Library were searched for articles published between 1991 and April 2014. English language articles with a focus on suicide-related behaviour and social media were included. No exclusion was placed on study design.

RESULTS

Thirty studies were included; 4 described the development of social media sites designed for suicide prevention, 6 examined the potential of social media in terms of its ability to reach or identify people at risk of suicide, 15 examined the ways in which people used social media for suicide prevention-related purposes, and 5 examined the experiences of people who had used social media sites for suicide prevention purposes. No intervention studies were identified.

CONCLUSION

Social media platforms can reach large numbers of otherwise hard-to-engage individuals, may allow others to intervene following an expression of suicidal ideation online, and provide an anonymous, accessible and non-judgmental forum for sharing experiences. Challenges include difficulties controlling user behaviour and accurately assessing risk, issues relating to privacy and confidentiality and the possibility of contagion. Social media appears to hold significant potential for suicide prevention; however, additional research into its safety and efficacy is required.

Coping Card Usage can Further Reduce Suicide Reattempt in Suicide Attempter Case Management Within 3-Month Intervention

This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3-month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2-month and 3-month intervention periods.

The safety and acceptability of delivering an online intervention to secondary students at risk of suicide: findings from a pilot study

BACKGROUND

Suicide-related behaviour is a major problem among adolescents. Yet relatively few studies have tested the efficacy, acceptability and safety of interventions for this population. We developed and pilot tested an online intervention for at-risk school students, which has led to reduced suicidal ideation, hopelessness and depressive symptoms. The aims of this study were to examine the safety and acceptability of the programme, and to determine which components were found to be most helpful and enjoyable.

METHODS

This pilot study employed a pre-test/post-test design, with an 8-week intervention phase. Participants were assessed immediately before, and immediately after the intervention. Participants were also asked to complete a weekly questionnaire immediately after the intervention, and again 2 days later assessing suicidal ideation and distress.

RESULTS

Twenty-one young people completed the intervention. Overall, the intervention did not lead to increases in suicidal ideation or distress. Participants reported enjoying the programme, in particular watching the video diaries and completing the activities, and said they would recommend the programme to a friend. Overall, the cognitive components of the programme were found to be most helpful.

CONCLUSIONS

Overall, the programme appeared to be a safe and acceptable intervention for at-risk adolescents. This was a small, pilot study so we need to interpret the results with caution. However, the findings are promising and suggest that young people at risk of suicide can safely be included in trials as long as adequate safety procedures are in place. The programme is now being tested in a randomized controlled trial.

Risk factors associated with purchasing pesticide from shops for self-poisoning: a protocol for a population-based case-control study

INTRODUCTION

Pesticide self-poisoning is one of the most frequently used methods of suicide worldwide, killing over 300,000 people annually. Around 15-20% of pesticide self-poisonings occur soon after the person has bought the pesticide from a shop. We aim to determine the characteristics of individuals who purchase pesticides directly from shops and how they differ from individuals who access pesticides from other sources such as home, home garden or farmland. This information will help inform possible vendor/shop-based intervention strategies aimed at reducing access to pesticides used for self-harm.

METHODS AND ANALYSIS

This study will investigate risk factors associated with purchasing pesticides for acts of self-poisoning from pesticide shops, including cases identified over a 9-month period using a population-based case-control group approach. Four interviewer-administered data collection tools will be used for this study: a semistructured questionnaire, Beck Suicidal Intent Scale (SIS), Clinical Interview Schedule-Sinhalese version (CIS-Sn) and Alcohol Use Disorders Identification Test (AUDIT). Each case (expected n=33) will be compared with two groups of individuals: (1) those who have self-poisoned using pesticides from the home, home garden or farmland and (2) those who bought pesticides from the same shops as the above cases, but not did not self-poison. Logistic regression models will be used to identify risk factors of purchasing pesticides for self-poisoning from shops.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Ethical Review Committee of the Faculty of Medicine and Allied Sciences, Rajarata University of Sri Lanka. A sensitive data collection technique will be used and ethical issues will be considered throughout the study. Results will be disseminated in scientific peer-reviewed articles.

Are people at risk of psychosis also at risk of suicide and self-harm? A systematic review and meta-analysis

BACKGROUND

Suicide and self-harm are prevalent in individuals diagnosed with psychotic disorders. However, less is known about the level of self-injurious thinking and behaviour in those individuals deemed to be at ultra-high risk (UHR) of developing psychosis, despite growing clinical interest in this population. This review provides a synthesis of the extant literature concerning the prevalence of self-harm and suicidality in the UHR population, and the predictors and correlates associated with these events.

METHOD

A search of electronic databases was undertaken by two independent reviewers. A meta-analysis of prevalence was undertaken for self-harm, suicidal ideation and behaviour. A narrative review was also undertaken of analyses examining predictors and correlates of self-harm and suicidality.

RESULTS

Twenty-one eligible studies were identified. The meta-analyses suggested a high prevalence of recent suicidal ideation (66%), lifetime self-harm (49%) and lifetime suicide attempts (18%). Co-morbid psychiatric problems, mood variability and a family history of psychiatric problems were among the factors associated with self-harm and suicide risk.

CONCLUSIONS

Results suggest that self-harm and suicidality are highly prevalent in the UHR population, with rates similar to those observed in samples with diagnosed psychotic disorders. Appropriate monitoring and managing of suicide risk will be important for services working with the UHR population. Further research in this area is urgently needed considering the high rates identified.

APSI: a proposed integrative model for suicide prevention

BACKGROUND

Deaths by suicide have been increasing in recent years in Ireland, many of whom have co-morbid mental health difficulties and/or have attended primary care services 1 month before death. Aims To profile how 'Access to Psychological Services Ireland' (APSI) provides stepped-care therapies for mild-to-moderate adult mental health presentations and the potential effectiveness of this model based on comparison to a review of evidence-based strategies in suicide prevention. A secondary aim is to highlight how APSI has the potential to target those at risk of suicide and provide an integrative after-care service to complement secondary care mental health services. Findings In a context of inter-agency working, APSI provides an integrated continuum of suicide prevention interventions that map onto or intervene across the continuum of suicide behaviour. Hence, APSI appears to implement what the literature suggests will work in preventing suicide. However, outcome research is needed to establish APSI's impact in preventing suicide. Recommendations It is recommended that Irish-based research is conducted to establish APSI's impact in preventing suicide with a view to rolling out APSI as a national mental health clinical care programme.

The development of a randomised controlled trial testing the effects of an online intervention among school students at risk of suicide

BACKGROUND

Suicide-related behaviour among young people is of significant concern, yet little is known regarding the effectiveness of interventions designed to reduce risk among this population. Of those interventions that have been tested, cognitive-behavioural therapy appears to show some promise among young people with suicidal ideation. Internet-based interventions are becoming increasingly popular and have shown some effect in preventing and treating depression and anxiety in young people. However, to date there are no randomised controlled trials examining the impact of Internet-based Cognitive Behavioural Therapy among suicidal youth.

METHODS/DESIGN

This is a randomised controlled trial testing the effects of Internet-based cognitive-behavioural therapy among suicidal high school students who have sought help from the school wellbeing team. The intervention comprises 8 modules of Cognitive Behavioural Therapy delivered online. The study has a staggered, two-year recruitment phase and participants are assessed at baseline, post intervention and 12 weeks later.

DISCUSSION

If effective the program has the ability to be readily adapted and delivered to a range of populations in a range of settings, at relatively little cost. It can also be adapted for mobile applications.

Psychosocial interventions for suicidal ideation, plans, and attempts: a database of randomised controlled trials

BACKGROUND

Research in suicide prevention using psychosocial interventions is rapidly advancing. However, randomised controlled trials are published across a range of medical, psychological and sociology journals, and it can be difficult to locate a full set of research studies. In this paper, we present a database of randomised controlled outcome studies on psychosocial interventions targeting suicidal behaviour. The database is updated annually and can be accessed by contacting the corresponding author.

DESCRIPTION

A comprehensive literature search of the major bibliographical databases (PsycINFO; PubMed; Cochrane Central Register of Controlled Trials) was conducted for articles published between 1800 to July 30 2013, and examined reference lists of previous relevant reviews and included papers to locate additional references. Studies were included if they featured a randomised controlled design in which the effects of a psychosocial intervention were compared to a control condition (no intervention, attention placebo, wait-list, treatment-as-usual [TAU]), another psychosocial intervention or a pharmacological intervention. In total, 12,250 abstracts were identified. Of these, 131 studies met eligibility criteria and were included. Each paper was then coded into categories of participant characteristics (age, gender, formal diagnosis, primary reason for recruitment); details of the intervention (recruitment setting, content, intervention setting, administering individual, delivery type, delivery format, delivery frequency, delivery length); and study characteristics (control and experimental conditions, primary outcome/s, secondary outcome/s, follow-up period). One paper has been published from the database using studies collected and coded prior to 2012.

CONCLUSION

The database and listing of 131 studies is available for use by suicide prevention researchers. It provides a strong starting point for systematic reviews and meta-analyses of treatments and interventions. It will be updated yearly by researchers funded through the Australian National Health and Medical Research Council Centre for Research Excellence for Suicide Prevention (CRESP), located at the Black Dog Institute, Australia. This database adds to the evidence base of best-practice psychosocial interventions for suicidal behaviour and prevention.

Research priorities in suicide prevention: an examination of Australian-based research 2007–11

Objective Suicide prevention, including among youth, has been a national priority in Australia for some time. Yet despite this, rates of suicide, and related behaviour, remain high. The aim of this study was to review all suicide-prevention research that had been conducted in Australia between January 2007 and December 2011, with a specific emphasis on studies relating to young people, in order to determine whether or not we are prioritising the sort of research that can adequately inform policy development and guide ‘best practice’. Methods Data were collected from two sources. First, several electronic databases were searched in October 2012 in order to identify published journal articles relating to suicide, written by Australian authors. Second, summary data obtained from the National Health and Medical Research Council, the Australian Rotary Health Research Fund and the Australian Research Council were examined in order to identify currently funded studies that relate to suicide. Studies were then classified according to whether or not they had a focus on youth, and according to research type, type of suicide-related behaviour under investigation and method of suicide. Results There were 224 articles published and 12 grants funded that specifically focussed on suicide-related behaviour over the period January 2007 to December 2011. Of these, 47 articles (21%) and five funded grants (42%) focussed on young people. Youth studies, in particular those reported in the published articles, tended to be epidemiological in nature and only six of the published articles (13%) and two of the funded grants related to intervention studies. Conclusions Although the focus on youth is welcome, the lack of intervention studies is disappointing. Given that rates of suicide and related behaviour remain high, there is a clear need for a stronger body of intervention research that can inform national policy, if we are to successfully develop effective approaches to reducing suicide risk. What is known about the topic? Although the prevention of youth suicide has been a national priority for some time, rates of suicide and suicide-related behaviour remain high among young Australians. Much is known about the epidemiology of suicide; however, relatively little is known about which interventions may be effective in reducing this risk. Previous research suggests that although youth receive a reasonable amount of research attention in Australia, the majority of studies focus on epidemiological as opposed to intervention research. What does this paper add? This paper reviews all suicide research that has been conducted in Australia between 2007 and 2011 in order to examine how much attention is currently given to studies relating to youth, and the relative priority given to intervention and epidemiological studies. Our findings support those reported previously, which suggest that although a significant proportion of suicide research focuses on youth, relatively little attention continues to be given to intervention studies. What are the implications for practitioners? This paper argues that further intervention research is needed if we are to build a sufficiently strong evidence base that can effectively inform policy development and guide best practice when it comes to preventing youth suicide in Australia.

The predictors of suicidality in previous suicide attempters following case management services

Suicide attempts constitute a serious clinical problem. People who have attempted suicide are at an elevated risk for additional suicide attempts, but there is limited evidence regarding the predictors of suicidality of suicide attempters following case management services. In the present study the indicators of suicidality after case management were examined. A total of 1,056 subjects who had recently attempted suicide were recruited from January 1, 2011, to June 30, 2011. The suicide prevention center of Kaohsiung City in Taiwan provided case management services and followed up on suicide attempt cases for 6 months. The salient factors for repeat suicide attempts were estimated using a logistic regression analysis. The results showed that multiple factors, including a "willingness to receive mental health services during a crisis," "social support," "a history of mental disorders," and "a history of suicide," could predict repeat suicide attempts with hazard ratios (0.58, 0.54, 3.84, 1.51) and 95% confidence interval (0.39-0.86, 0.36-0.83, 2.41-6.10, 1.03-2.21). The four factors mentioned above were the most accurate predictors of subsequent suicidality when case management services were utilized after 6 months of follow-up. The findings of our study could help clarify future strategies for suicide prevention.

Employing crisis postcards with case management in Kaohsiung, Taiwan: 6-month outcomes of a randomised controlled trial for suicide attempters

BACKGROUND

Suicide attempts constitute a serious clinical problem and have important implications for healthcare resources. The aim of the present study was to evaluate the effectiveness of case management using crisis postcards over a 6-month follow-up period.

METHOD

A randomised controlled trial was conducted in Kaohsiung, Taiwan. Prevention of further suicide attempts was compared between two groups with and without the postcard intervention. The intervention group consisted of 373 participants (139 males, 234 females; age: 39.8 ± 14.0 yrs.). The control group consisted of 388 participants (113 males, 275 females; age: 40.0 ± 16.0 yrs.). A survival analysis was used to test the effectiveness of the crisis postcard intervention for the prevention of suicide reattempts. Per-protocol and intention-to-treat analyses were conducted.

RESULTS

The intention-to-treat analysis indicated that the crisis postcard had no effect (hazard ratio = 0.84; 95% CI = 0.56 - 1.29), whereas the per-protocol analysis showed a strong benefit for the crisis postcard (hazard ratio = 0.39; 95% CI = 0.21 - 0.72).

CONCLUSION

Although the results of the present study indicated that the postcard intervention did not reduce subsequent suicide behaviour, our study provides an alteration to the postcard intervention. Further studies need to be conducted to clarify whether this type of intervention can reduce subsequent suicidal behaviour, with a particular focus on reducing the rate of loss to follow-up.

Preventing addiction related suicide: a pilot study

Persons addicted to alcohol and drugs are at 5-10 times higher risk for suicide as compared to the general population. To address the need for improved suicide prevention strategies in this population, the Preventing Addiction Related Suicide (PARS) module was developed. Pilot testing of 78 patients demonstrated significant post-treatment changes in knowledge [t(66) = 12.07, p = .000] and attitudes [t(75) = 6.82, p = .000] toward suicide prevention issues. Significant gains were maintained at 1-month follow-up for changes in knowledge [t(55) = 6.33, p = .000] and attitudes [t(61) = 3.37, p = .0001], with changes in positive help seeking behaviors in dealing with suicidal issues in friends [χ(2)(1) = 10.49, p = .007], family [χ(2)(1) = 9.81, p = .015], and self [χ(2)(1) = 19.62, p = .008] also observed. The PARS was also highly rated by treatment staff as feasible within their standard clinical practice.

Community-based case management for the prevention of suicide reattempts in Kaohsiung, Taiwan

Although a previous suicide attempt constitutes a major risk factor for an eventual completed suicide, few interventions specifically designed to prevent suicide reattempt shave been evaluated. The aim of this study was to determine the effectiveness of case management for the prevention of suicide reattempts. A total of 4,765 subjects with a recent suicide attempt referred from medical and non-medical organizations were consecutively recruited from July 2006 to June 2008. The suicide prevention program of Kaohsiung Suicide Prevention Center (KSPC)provided case management and followed up suicide attempt cases for 6 months. Survival analysis showed that the risk of suicide reattempt was significantly lower in the case management group than in the non-contact group throughout a six-month follow-up period (hazard ratio =2.93; 95% CI = 2.47–3.47). The hazard ratio (HR) of the Cox proportional hazard model for sex was 0.77 (95%CI = 0.65–0.91). Case management appears to be effective in preventing suicide reattempts in patients with a recent prior attempt. In addition, case management appeared to be more beneficial in preventing suicide reattempts in male subjects.

Latent variable model for suicide risk in relation to social capital and socio-economic status

BACKGROUND

There is little evidence on the association between suicide outcomes (ideation, attempts, self-harm) and social capital. This paper investigates such associations using a structural equation model based on health survey data, and allowing for both individual and contextual risk factors.

METHODS

Social capital and other major risk factors for suicide, namely socioeconomic status and social isolation, are modelled as latent variables that are proxied (or measured) by observed indicators or question responses for survey subjects. These latent scales predict suicide risk in the structural component of the model. Also relevant to explaining suicide risk are contextual variables, such as area deprivation and region of residence, as well as the subject's demographic status. The analysis is based on the 2007 Adult Psychiatric Morbidity Survey and includes 7,403 English subjects. A Bayesian modelling strategy is used.

RESULTS

Models with and without social capital as a predictor of suicide risk are applied. A benefit to statistical fit is demonstrated when social capital is added as a predictor. Social capital varies significantly by geographic context variables (neighbourhood deprivation, region), and this impacts on the direct effects of these contextual variables on suicide risk. In particular, area deprivation is not confirmed as a distinct significant influence. The model develops a suicidality risk score incorporating social capital, and the success of this risk score in predicting actual suicide events is demonstrated.

CONCLUSIONS

Social capital as reflected in neighbourhood perceptions is a significant factor affecting risks of different types of self-harm and may mediate the effects of other contextual variables such as area deprivation.

Promoting CARE: including parents in youth suicide prevention

This study evaluated the effectiveness of augmenting a youth suicide-preventive intervention with a brief, home-based parent program. A total of 615 high school youth and their parents participated. Three suicide prevention protocols, a youth intervention, a parent intervention, and a combination of youth and parent intervention, were compared with an "intervention as usual" (IAU) group. All groups experienced a decline in risk factors and an increase in protective factors during the intervention period, and sustained these improvements over 15 months. Results reveal that the youth intervention and combined youth and parent intervention produced significantly greater reductions in suicide risk factors and increases in protective factors than IAU comparison group.

Can receipt of a regular postcard reduce suicide-related behaviour in young help seekers? A randomized controlled trial

AIM

Suicide attempt, ideation and deliberate self-harm are common among adolescents. Limited evidence exists regarding interventions that can reduce risk; however, research indicates that maintaining contact with at-risk adults following discharge from services via letter or postcard can reduce risk. The aim of the study was to test a postcard intervention among people aged 15-24 who presented to mental health services but were not accepted, yet were at risk of suicide.

METHODS

A randomized controlled trial of 3 years in duration was used. The intervention consisted of 12 postcards sent once a month for 12 months following presentation to the service. Key outcomes of interest were reduced rates of suicide attempt, suicidal ideation and deliberate self-harm, assessed at 12 and 18 months.

RESULTS

Participants reported that they liked receiving the postcard and that they used the strategies recommended. However, no significant effect of the postcard intervention was found on suicide risk, although participants in both groups improved on measures of mental health over the course of the study.

CONCLUSIONS

There remains a need for further research into youth-friendly interventions for young people at risk of suicide.

Best practice elements of multilevel suicide prevention strategies: a review of systematic reviews

Background: Evidence-based best practices for incorporation into an optimal multilevel intervention for suicide prevention should be identifiable in the literature. Aims: To identify effective interventions for the prevention of suicidal behavior. Methods: Review of systematic reviews found in the Pubmed, Cochrane, and DARE databases. Steps include risk-of-bias assessment, data extraction, summarization of best practices, and identification of synergistic potentials of such practices in multilevel approaches. Results: Six relevant systematic reviews were found. Best practices identified as effective were as follows: training general practitioners (GPs) to recognize and treat depression and suicidality, improving accessibility of care for at-risk people, and restricting access to means of suicide. Although no outcomes were reported for multilevel interventions or for synergistic effects of multiple interventions applied together, indirect support was found for possible synergies in particular combinations of interventions within multilevel strategies. Conclusions: A number of evidence-based best practices for the prevention of suicide and suicide attempts were identified. Research is needed on the nature and extent of potential synergistic effects of various preventive activities within multilevel interventions.

Suicide prevention is possible: A perception after suicide attempt

BACKGROUND

Suicide is a preventable cause of death, inspite of which its incidence is increasing worldwide. Very few studies are done to know the perception of suicide attempters regarding prevention of their suicide attempt. Such information may be helpful in implementing preventive strategies. This study was done to find out whether those who attempted suicide and recovered perceived that their suicide attempt could have been prevented or not.

MATERIALS AND METHODS

Fifty consecutive subjects were recruited by purposive sampling method. These subjects were admitted for suicide attempt and were stable after medical management. Subjects were assessed using socio-demographic and clinical proforma, Pierce suicide intent scale and structured questionnaire to assess their perception regarding suicide. Group differences for categorical variables were examined with the chi-square test, whereas an independent 't' test was used for continuous variables.

RESULTS

Analysis revealed that 80% of suicide attempters felt that their suicide attempt could have been prevented. 64% of the study subjects perceived that family members and near and dear ones could have helped in preventing their attempt while 16% of the study subjects perceived that society could have helped.

CONCLUSIONS

Majority of subjects on recovery from the suicide attempt perceived that their suicide attempt could have been prevented by family members, near and dear ones and society.

Implementation of mental health service recommendations in England and Wales and suicide rates, 1997-2006: a cross-sectional and before-and-after observational study

BACKGROUND

Research investigating which aspects of mental health service provision are most effective in prevention of suicide is scarce. We aimed to examine the uptake of key mental health service recommendations over time and to investigate the association between their implementation and suicide rates.

METHODS

We did a descriptive, cross-sectional, and before-and-after analysis of national suicide data in England and Wales. We collected data for individuals who died by suicide between 1997 and 2006 who were in contact with mental health services in the 12 months before death. Data were obtained as part of the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness. When denominator data were missing, we used information from the Mental Health Minimum Data Set. We compared suicide rates for services implementing most of the recommendations with those implementing fewer recommendations and examined rates before and after implementation. We stratified results for level of socioeconomic deprivation and size of service provider.

FINDINGS

The average number of recommendations implemented increased from 0·3 per service in 1998 to 7·2 in 2006. Implementation of recommendations was associated with lower suicide rates in both cross-sectional and before-and-after analyses. The provision of 24 h crisis care was associated with the biggest fall in suicide rates: from 11·44 per 10 000 patient contacts per year (95% CI 11·12-11·77) before to 9·32 (8·99-9·67) after (p<0·0001). Local policies on patients with dual diagnosis (10·55; 10·23-10·89 before vs 9·61; 9·18-10·05 after, p=0·0007) and multidisciplinary review after suicide (11·59; 11·31-11·88 before vs 10·48; 10·13-10·84 after, p<0·0001) were also associated with falling rates. Services that did not implement recommendations had little reduction in suicide. The biggest falls in suicide seemed to be in services with the most deprived catchment areas (incidence rate ratio 0·90; 95% CI 0·88-0·92) and the most patients (0·86; 0·84-0·88).

INTERPRETATION

Our findings suggest that aspects of provision of mental health services can affect suicide rates in clinical populations. Investigation of the relation between new initiatives and suicide could help to inform future suicide prevention efforts and improve safety for patients receiving mental health care.

A community-based cluster randomised trial of safe storage to reduce pesticide self-poisoning in rural Sri Lanka: study protocol

Background

The WHO recognises pesticide poisoning to be the single most important means of suicide globally. Pesticide self-poisoning is a major public health and clinical problem in rural Asia, where it has led to case fatality ratios 20-30 times higher than self-poisoning in the developed world. One approach to reducing access to pesticides is for households to store pesticides in lockable "safe-storage" containers. However, before this approach can be promoted, evidence is required on its effectiveness and safety.

Methods/Design

A community-based cluster randomised controlled trial has been set up in 44,000 households in the North Central Province, Sri Lanka. A census is being performed, collecting baseline demographic data, socio-economic status, pesticide usage, self-harm and alcohol. Participating villages are then randomised and eligible households in the intervention arm given a lockable safe storage container for agrochemicals.

The primary outcome will be incidence of pesticide self-poisoning over three years amongst individuals aged 14 years and over. 217,944 person years of follow-up are required in each arm to detect a 33% reduction in pesticide self-poisoning with 80% power at the 5% significance level. Secondary outcomes will include the incidence of all pesticide poisoning and total self-harm.

Discussion

This paper describes a large effectiveness study of a community intervention to reduce the burden of intentional poisoning in rural Sri Lanka. The study builds on a strong partnership between provincial health services, local and international researchers, and local communities. We discuss issues in relation to randomisation and contamination, engaging control villages, the intervention, and strategies to improve adherence.

Integrating medical examiner and police report data: can this improve our knowledge of the social circumstances surrounding suicide?

BACKGROUND

Recently, suicide in the United States has begun to be viewed as a preventable public health issue. This has led to the creation of a National Violent Death Reporting System that collects and integrates data on the social circumstances surrounding suicides.

AIMS

The study examines data on social circumstances surrounding suicides as collected by the medical examiner report (ME) and police report (PR) and subsequently integrated into the state of Maryland's violent death reporting system.

METHODS

Reported data on social circumstances surrounding suicides occurring in the years 2003-2006 in Maryland (n = 1,476) were analyzed by examining their prevalence in the ME and PR, strength of association, and integration.

RESULTS

With the exception of three circumstances, there was variation among reported circumstances in the ME and PR. Furthermore, there was only a moderately strong relationship between the ME and PR for most circumstances, while a significant increase occurred in the prevalence of these circumstances when ME and PR were integrated.

CONCLUSIONS

The integration of ME and PR has the potential to increase our knowledge of the circumstances surrounding suicide and to better inform prevention efforts. However, before this potential can be reached, there are still issues that must be considered.

Chain of care for patients who have attempted suicide: a follow-up study from Bærum, Norway

BACKGROUND

Individuals who have attempted suicide are at increased risk of subsequent suicidal behavior. Since 1983, a community-based suicide prevention team has been operating in the municipality of Bærum, Norway. This study aimed to test the effectiveness of the team's interventions in preventing repeated suicide attempts and suicide deaths, as part of a chain of care model for all general hospital treated suicide attempters.

METHODS

Data has been collected consecutively since 1984 and a follow-up was conducted on all individuals admitted to the general hospital after a suicide attempt. The risk of repeated suicide attempt and suicide were comparatively examined in subjects who received assistance from the suicide prevention team in addition to treatment as usual versus those who received treatment as usual only. Logistic regression and Cox regression were used to analyze the data.

RESULTS

Between January 1984 and December 2007, 1,616 subjects were registered as having attempted suicide; 197 of them (12%) made another attempt within 12 months. Compared to subjects who did not receive assistance from the suicide prevention team, individuals involved in the prevention program did not have a significantly different risk of repeated attempt within 6 months (adjusted OR = 1.08; 95% CI = 0.66-1.74), 12 months (adjusted OR = 0.86; 95% CI = 0.57-1.30), or 5 years (adjusted RR = 0.90; 95% CI = 0.67-1.22) after their first recorded attempt. There was also no difference in risk of suicide (adjusted RR = 0.85; 95% CI = 0.46-1.57). Previous suicide attempts, marital status, and employment status were significantly associated with a repeated suicide attempt within 6 and 12 months (p < 0.05). Alcohol misuse, employment status, and previous suicide attempts were significantly associated with a repeated attempt within 5 years (p < 0.05) while marital status became non-significant (p > 0.05). With each year of age, the risk of suicide increased by 3% (p < 0.05).

CONCLUSIONS

The present study did not find any differences in the risk of fatal and non-fatal suicidal behavior between subjects who received treatment as usual combined with community assistance versus subjects who received only treatment as usual. However, assistance from the community team was mainly offered to attempters who were not receiving sufficient support from treatment as usual and was accepted by 50-60% of those deemed eligible. Thus, obtaining similar outcomes for individuals, all of whom were clinically judged to have different needs, could in itself be considered a desirable result.

Preventing suicide in young people: systematic review

OBJECTIVE

Risk of suicide attempt, suicidal ideation and deliberate self-harm is high among young people, yet limited evidence exists regarding effective interventions, particularly from randomized controlled trials. The aim of this study was to conduct a systematic review and meta-analysis of all randomized controlled trials testing interventions for adolescents and young adults who have presented to a clinical setting with any of these behaviours.

METHODS

The Cochrane Central Register of Controlled Trials, Medline, EMBASE and PsycINFO were searched for articles published from 1980 to June 2010. The following keywords formed the basis of the search strategy: 'self-injurious behaviour', 'attempted suicide', 'suicide', 'suicidal behaviour', 'self-inflicted wounds', 'self-mutilation', 'self-harm'. We also hand searched conference abstracts from two major suicide prevention conferences and the reference lists of all retrieved articles and previous reviews.

RESULTS

There were 15 trials included in the review, with six ongoing trials also identified. In general, the reporting of the conduct of trials was poor, making it difficult to assess the risk of bias. The reporting of outcome data was inconsistent. No differences were found between treatment and control groups except in one study that found a difference between individual cognitive behavioural therapy and treatment as usual.

CONCLUSION

The evidence regarding effective interventions for adolescents and young adults with suicide attempt, deliberate self-harm or suicidal ideation is extremely limited. Many more methodologically rigorous trials are required. However, in the meantime CBT shows some promise, but further investigation is required in order to determine its ability to reduce suicide risk among young people presenting to clinical services.

Intervention Studies in Suicide Prevention Research

Background: Despite the growing strength of the field of suicidology, various commentators have recently noted that insufficient effort is being put into intervention research, and that this is limiting our knowledge of which suicide prevention strategies might be the most effective. Aims: To profile the types of studies currently being undertaken by suicide prevention researchers from around the world, in order to examine the relative balance between intervention studies and other types of research. Methods: We searched the abstract books from the 22nd, 23rd, and 24th Congresses of the International Association for Suicide Prevention and the 10th, 11th, and 12th European Symposia on Suicide and Suicidal Behavior (held between 2003 and 2008), and classified the abstracts in them according to a modified version of an existing taxonomy. Results: We screened 1209 abstracts and found that only 12% described intervention studies. Conclusions: We need to redouble our efforts and make intervention studies our priority if we are to combat the global problem of suicide.

The effectiveness of a web-based self-help intervention to reduce suicidal thoughts: a randomized controlled trial

Background

Suicide, attempted suicide and suicidal thoughts are major public health problems worldwide. Effective face-to-face treatments are Cognitive Behavioural Therapy (CBT), Dialectical Behavioural Therapy (DBT) and Problem Solving Treatment (PST). However, about two-thirds of persons who die by suicide have not been in contact with mental health care services in the preceding year, and many have never been treated. Furthermore, many patients do not disclose their suicidal thoughts to their care provider. This may be out of shame, due to fear of stigma or due to lack of trust in (mental) health care. Since many suicidal individuals seek information online, the internet provides an opportunity to reach suicidal individuals who would not be contacted otherwise. By providing a self-help intervention online, persons can anonymously learn to gain control over their suicidal thoughts. There is convincing evidence that self-help is effective for a number of mental disorders. In this study the effectiveness for suicidal thoughts is examined.

Methods/Design

In this study, a recently developed self-help intervention will be evaluated in a Randomized Controlled Trial. The intervention is based on Cognitive Behavioural Therapy and is aimed at subjects who experience mild to moderate suicidal thoughts. This is defined as a score between 1 and 26 on the Beck Scale for Suicidal Ideation (BSS). Higher and lower scores are excluded. In addition, severely depressed subjects are excluded. In total, 260 subjects will be randomly allocated to the intervention-condition (N = 130) or to the information-control condition (N = 130). Self-report questionnaires will be filled out at baseline, 6 weeks after baseline and 18 weeks after baseline. Primary outcome measure is the reduction in frequency and intensity of suicidal thoughts. Secondary outcome measures are the reduction of hopelessness, anxiety and depression, sleeplessness, worry and quality of life measures.

Discussion

This study is the first to evaluate the effectiveness of a web-based self-help intervention for suicidal thoughts. Several limitations and strengths of the design are discussed.

Study protocol: the development of a randomised controlled trial testing a postcard intervention designed to reduce suicide risk among young help-seekers

BACKGROUND

Suicidal behaviour and deliberate self harm are common among adolescents. Limited evidence exists regarding interventions that can reduce risk; however research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from services can reduce risk. The aim of the study is to test a postcard intervention among people aged 15-24 who presented to mental health services but are not accepted, yet are at risk of suicide.

METHODS/DESIGN

The study is a 3-year randomised controlled trial conducted at Orygen Youth Health Research Centre in Melbourne Australia. Participants are young help-seekers aged 15-24 who are at risk of suicide. Participants will be recruited over a 12 month period. The intervention comprises a regular postcard to be sent monthly for 12 months. The postcard enquires after their well being and includes information regarding individual sources of help and evidence-based self help strategies. Participants are assessed at baseline, 12 and 18 months.

DISCUSSION

This paper describes the development of a study which aims to reduce suicide risk in a sample of young help-seekers. If effective, this intervention could have significant clinical and research implications for a population who can be hard to treat and difficult to research.

TRIAL REGISTRATION

The study was registered with the Australian Clinical Trials Registry; number: ACTRN012606000274572.

Managing deliberate self-harm in young people: an evaluation of a training program developed for school welfare staff using a longitudinal research design

BACKGROUND

Although deliberate self-harm is prevalent among young people, many who engage in deliberate self-harm receive sub-optimal care. Although schools are a well placed setting to support young people who engage in self-harm there are no specific training packages designed to assist school welfare staff to support these young people.The current study aimed to design, deliver and evaluate a training course specifically for school staff.

METHODS

The study employed a longitudinal design. Two hundred and thirteen people participated in the training and evaluation. A questionnaire was administered at baseline, immediately after the training and at 6-month follow-up in order to determine if the training led to improvements in confidence when working with young people who self-harm, perceived skill, knowledge of, and attitudes towards people who self harm.

RESULTS

Prior to the course, the majority of participants demonstrated relatively high levels of confidence, perceived skill and knowledge of self-harm and endorsed relatively positive attitudes towards people who engage in self-harm. Despite this, significant improvements were observed in terms of increased confidence, increased perceptions of skill along with increased knowledge of deliberate self-harm. These improvements were sustained over the follow-up period.

CONCLUSION

The results demonstrated that the provision of specifically designed training can help school welfare staff to feel better equipped to support young people who are engaging in deliberate self-harm.

A community intervention trial of multimodal suicide prevention program in Japan: a novel multimodal community intervention program to prevent suicide and suicide attempt in Japan, NOCOMIT-J

Background

To respond to the rapid surge in the incidence of suicide in Japan, which appears to be an ongoing trend, the Japanese Multimodal Intervention Trials for Suicide Prevention (J-MISP) have launched a multimodal community-based suicide prevention program, NOCOMIT-J. The primary aim of this study is to examine whether NOCOMIT-J is effective in reducing suicidal behavior in the community.

Methods/DesignThis study is a community intervention trial involving seven intervention regions with accompanying control regions, all with populations of statistically sufficient size. The program focuses on building social support networks in the public health system for suicide prevention and mental health promotion, intending to reinforce human relationships in the community. The intervention program components includes a primary prevention measures of awareness campaign for the public and key personnel, secondary prevention measures for screening of, and assisting, high-risk individuals, after-care for individuals bereaved by suicide, and other measures. The intervention started in July 2006, and will continue for 3.5 years. Participants are Japanese and foreign residents living in the intervention and control regions (a total of population of 2,120,000 individuals).

Discussion

The present study is designed to evaluate the effectiveness of the community-based suicide prevention program in the seven participating areas.

The relationship between suicide ideation and late-life depression

OBJECTIVE

To describe the course of suicide ideation (SI) in primary-care based late-life depression treatment, identify predictors of SI, characterize the dynamic relationship between depression and SI, and test the hypothesis that collaborative care decreases the likelihood of reporting SI by decreasing the severity of depressive symptoms.

METHODS

This was a secondary analysis of a randomized controlled trial comparing collaborative care to usual care for late-life depression. Participants were 1,801 adults age 60 and older from eight diverse primary-care systems. Depression was measured using the Hopkins Symptoms Checklist (HSCL-20). SI was operationalized using one item from the HSCL-20. Predictors of incident SI were identified by a series of univariate analyses followed by multiple logistic regression. A mediator analysis was conducted to test the hypothesis that the effect of collaborative care on SI can be ascribed to the intervention's effect on depressive symptoms.

RESULTS

The prevalence of SI was 14% (N = 253); the cumulative incidence over 24 months was 21% (385). The likelihood that SI emerged after baseline was highly dependent on change in depression (odds ratio: 5.38, 95% confidence interval: 3.93-7.36, df = 81, t = 10.66, p <0.0001). As hypothesized, the effect of collaborative care on SI was mediated by the treatment's effect on depression.

CONCLUSION

SI is not uncommon in depressed older adults being treated in primary care. The likelihood that depressed older adults will report SI is strongly determined by the course of their depression symptoms. Providers should monitor SI throughout the course of depression treatment.

Treatment and prevention of mental disorders in low-income and middle-income countries

We review the evidence on effectiveness of interventions for the treatment and prevention of selected mental disorders in low-income and middle-income countries. Depression can be treated effectively in such countries with low-cost antidepressants or with psychological interventions (such as cognitive-behaviour therapy and interpersonal therapies). Stepped-care and collaborative models provide a framework for integration of drug and psychological treatments and help to improve rates of adherence to treatment. First-generation antipsychotic drugs are effective and cost effective for the treatment of schizophrenia; their benefits can be enhanced by psychosocial treatments, such as community-based models of care. Brief interventions delivered by primary-care professionals are effective for management of hazardous alcohol use, and pharmacological and psychosocial interventions have some benefits for people with alcohol dependence. Policies designed to reduce consumption, such as increased taxes and other control strategies, can reduce the population burden of alcohol abuse. Evidence about the efficacy of interventions for developmental disabilities is inadequate, but community-based rehabilitation models provide a low-cost, integrative framework for care of children and adults with chronic mental disabilities. Evidence for mental health interventions for people who are exposed to conflict and other disasters is still weak-especially for interventions in the midst of emergencies. Some trials of interventions for prevention of depression and developmental delays in low-income and middle-income countries show beneficial effects. Interventions for depression, delivered in primary care, are as cost effective as antiretroviral drugs for HIV/AIDS. The process and effectiveness of scaling up mental health interventions has not been adequately assessed. Such research is needed to inform the continuing process of service reform and innovation. However, we recommend that policymakers should act on the available evidence to scale up effective and cost-effective treatments and preventive interventions for mental disorders.

Assessing the impact of media guidelines for reporting on suicides in Austria: interrupted time series analysis

OBJECTIVE

Media guidelines for reporting on suicides are a widely used means of preventing imitative suicides, but scientific accounts of their impact on suicide numbers are sparse. This report provides an evaluation of the Austrian guidelines that were introduced in 1987 as a natural experiment.

METHODS

The impact of the guidelines was tested by applying an autoregressive integrated moving average (ARIMA) model and a linear regression model. In addition to a nationwide evaluation, Austria was divided into three areas according to regional differences in coverage rates of the collaborating newspapers and the impact of the intervention was tested for each area separately. Main outcome measures were the overall annual suicide numbers, and the numbers of Viennese subway suicides that were exceptionally newsworthy for the mass media. In order to test intermediate impacts, also quantitative and qualitative changes in media reporting after the introduction of the guidelines were analysed.

RESULTS

There was some evidence of a nationwide impact of the guidelines, calculated as a significant reduction of 81 suicides (95% confidence interval: -149 to -13; t = -2.32, df = 54, p <0.024) annually. This effect was particularly due to a significant reduction in the area with the highest coverage rates of the collaborating newspapers. Viennese subway suicides showed a highly significant level shift (t = -4.44, df = 19, p <0.001) and a highly significant trend change (t = -4.20, df = 19, p <0.001) after the introduction of the guidelines. These effects corresponded to significant changes in the quality and quantity of media reporting.

CONCLUSIONS

The present results clearly support the hypothesis that the media guidelines have had an impact on the quality of reporting as well as on suicidal behaviour in Austria, and stress the importance of collaborating with nationwide, but also with regional media to achieve efficacy. Further research is needed to provide an international insight into this public health issue.

Evidence-based practices project for suicide prevention

Suicide continues to be a serious public health problem. In response to this problem, a myriad of suicide prevention programs have been developed and employed across the United States. Unfortunately, the effectiveness of many of these programs is unknown because they have not been evaluated using rigorous methods. The Evidence-Based Practices Project (EBPP) for suicide prevention was created in 2002 to identify and promote evidence-based suicide prevention programs. In this paper the process and outcomes of the initial EBPP project within the context of the broader evidence-based movement are described, and the EBPPs creation of a best practice registry for suicide prevention is previewed.

Sleep and youth suicidal behavior: a neglected field

PURPOSE OF REVIEW

Sleep undergoes substantial changes during adolescence and suicide risk begins to increase during this period as well. This review focuses on recent literature on the relationship between sleep and suicidal behavior and proposes directions for future research.

RECENT FINDINGS

Adolescent sleep is characterized by widespread sleep restriction, irregular sleep schedules, daytime sleepiness, and elevated risk for sleep disturbances. More research on adolescent sleep and psychosocial impairment, psychiatric disorders, and suicidal behavior has been conducted. Suicidal psychiatric patients had more sleep disturbances including insomnia, hypersomnia, or nightmares than nonsuicidal patients. Shorter rapid eye movement latency and increased rapid eye movement activity have been noted to be a marker of suicidality in psychiatric patients. Epidemiological studies have demonstrated that insomnia, nightmares, and sleep insufficiency are associated with elevated risk for suicide. Although the link between insomnia and suicidal behavior appears to be mediated by depression, existing data suggest an independent predictive role of nightmares in future suicidal behavior.

SUMMARY

Sleep loss or disturbances are likely to signal an increased risk of future suicidal action in adolescents. Large-scale prospective studies and neurobiological studies are needed for a better understanding of the complex relationship between sleep, psychopathology, and youth suicidal behavior.
