Internet-based cognitive behavioural therapy for young people with suicide-related behaviour (Reframe-IT): a randomised controlled trial

Digital Interventions for Suicide Prevention

Background: Digital-based mobile interventions hold significant promise in preventing suicide. Although mixed, some evidence suggests these interventions are effective and capable of overcoming barriers such as cost and stigma. Aim(s): This review aimed to determine the effectiveness of digital interventions designed to address suicidal ideation and behaviors and the impacts of age, gender, and control group type on these outcomes. Methods: Databases were searched for randomized controlled trials (RCTs) on digital suicide interventions (apps/online programs) published before January 1, 2022. Data were analyzed using a random-effects model in Stata 17. Results: The search identified 4,317 articles, and 16 were included. Risk of bias analysis found studies to be of low-to-moderate quality. The random-effects model indicated a small but significant effect of treatment on suicidal ideation, k = 16, g = 0.11 (95% CI: 0-0.23), p = .049. Subgroup analyses found the interventions to have a significant effect on adults (g = 0.15, 95% CI: 0.03, 0.28, p = .01) but not adolescents. The interventions showed better effects compared to waitlist controls (g = 0.28, 95% CI: 0.19, 0.38) but not compared to treatment as usual or active controls [χ2(2) = 29.41, p < .001]. Limitations: Sample sizes across studies were insufficient for examining the effectiveness of digital interventions by gender. Limited studies reported on suicidal behaviors, so the impact of digital interventions on these behaviors could not be analyzed. Conclusions: This review found a significant effect of digital interventions for reducing suicidal ideation and highlights the importance of examining the effectiveness across subgroups.

Psychosocial Interventions for Preventing Mental Health Conditions in Adolescents With Emotional Problems: A Meta-Analysis

Mental health conditions constitute a major burden of disease for adolescents globally and can lead to significant adverse consequences. This systematic review aimed to identify if psychosocial interventions are effective in preventing mental health conditions in adolescents already experiencing emotional problems. We searched for randomized controlled trials comparing psychosocial interventions for preventing mental health conditions with care as usual in adolescents aged 10-19 who are experiencing symptoms of emotional problems. We searched PubMed/Medline, PsycINFO, ERIC, EMBASE, and ASSIA databases to identify studies. We found 82 eligible studies (n = 13,562 participants). Findings show that interventions can reduce mental health conditions and increase positive mental health. Across all reported time points, psychosocial interventions showed significant, small-to moderate-sized beneficial effects on preventing mental health conditions (SMD: -0.26, 95% CI [-0.42, -0.19] and small positive effects on positive mental health (SMD: 0.17, 95% CI [0.097, 0.29]. There were no statistically significant pooled findings suggesting that psychosocial interventions had either a positive or negative effect on self-harm or suicide; aggressive, disruptive and oppositional behavior; substance use; or school attendance. Despite the positive findings, a critical gap exists in the design of effective psychosocial interventions to reduce self-harm and suicide, and other risk behaviors in adolescents with symptoms of emotional problems.

Effectiveness of internet-based cognitive behavioral therapy in reducing suicidality among high-risk patients with depression: A multicenter randomized controlled trial in Korea

OBJECTIVES

To compare the effectiveness of Internet-based cognitive behavioral therapy (iCBT) + treatment as usual (TAU) to TAU in patients with major depressive disorder (MDD) and suicidal risk.

DESIGN

This study was a multicenter, 1:1 single-blind randomized controlled trial (RCT) in which only the assessors were blinded.

SETTING

5 tertiary hospitals in Korea.

PARTICIPANTS

190 patients with depression aged 18-44 years who had suicidal ideation at baseline or had attempted suicide within the past month.

INTERVENTION

iCBT, consisted of five sessions over 4 weeks, and TAU including psychotherapy and pharmacotherapy. Data were collected through assessments and self-reports at baseline and at 6, 16, and 28 weeks after randomization.

RESULTS

200 patients were randomized, while 10 patients withdrew their consent to the study. (iCBT + TAU = 97, TAU = 93). 39 patients in iCBT + TAU group and 30 patients in TAU group completed final follow-up. Suicidal attempt was observed in 3 patients in iCBT + TAU group and 2 patients in TAU group.

CONCLUSION

No significant difference presented in the number of suicide attempts between groups during the follow-up period. However, iCBT + TAU showed faster improvements in suicidal ideation intensity, depressive symptoms, and social stress than TAU in the short term, but were not sustained at the long-term follow-up.

Acceptability and Feasibility of a Blended School-Based Intervention to Prevent Suicidal Ideation Among Adolescents in Chile: Results from a Randomized Control Pilot Study

Suicide prevention programs delivered in school settings have been shown to reduce suicide attempts and ideation among adolescents. School-based digital interventions targeting at-risk youth are a promising avenue for suicide prevention, and some evidence has shown that blending digital and face-to-face components may improve the effectiveness. However, further evidence on its acceptability, feasibility, and effectiveness is needed, especially in Latin America, where mental health support is limited. Reframe-IT is an internet-based Cognitive Behavioral Therapy (CBT) program to reduce youth suicidal ideation in school settings. We created four complementary face-to-face CBT sessions and, through a pilot study, tested the acceptability, feasibility, and effectiveness of a blended intervention (Reframe-IT +) in adolescents (N = 52) from 6 public schools in Chile, randomized into two groups: Reframe-IT + (N = 33) and Control (N = 19). We found that the intervention was acceptable and feasible, with high degrees of satisfaction and adherence. We also observed a significant reduction in suicidal ideation and depressive symptoms in the intervention group compared to the control group at post-intervention. Our results suggest that the Reframe-IT + could be delivered as a suitable, acceptable, and effective intervention to reduce suicide ideation in adolescents in school settings. Further research is needed to confirm these preliminary results.

Reframe-IT+, an indicated preventive school-based intervention, reduces suicidal ideation among adolescents in vulnerable contexts in Chile

BACKGROUND

Suicide prevention programs delivered in school settings have been shown to reduce suicide attempts and ideation among adolescents. School-based digital interventions targeting at-risk youth are a promising avenue for suicide prevention, and some evidence has shown that blending digital and face-to-face components may improve the effectiveness. However, further evidence is needed, especially in Latin America, where mental health support is limited. We tested the effectiveness of the Reframe-IT+, a blended cognitive behavioral indicated intervention to reduce suicidal ideation, designed to be delivered in school settings. It includes 13 sessions, combining eight internet-based sessions and five face-to-face sessions.

METHODS

We conducted a cluster RCT and delivered the Reframe-IT + among secondary students attending Years 9-11. We recruited 21 schools that were randomized into two groups: (1) Intervention Reframe-IT + Group (IG) (n = 863) and (2) Control Group (CG) (n = 683). All consented students completed online screening self-reported questionnaires at baseline. The primary outcome was suicidal ideation . Additionally, we tested the impact of the intervention on depressive and anxiety symptoms, hopelessness, and emotion regulatory strategies, including social solving-problems skills, behavioral activation, cognitive reappraisal, and emotion suppression. A total of 303 students (IG, n = 164; CG, n = 139) were identified as at risk and eligible for inclusion in the study. From those, 224 students (IG, n = 123; CG, n = 101) and their caregivers were interviewed to confirm inclusion and exclusion criteria. Finally, 48 and 47 students were allocated to control and intervention groups, respectively, and answered the online questionnaires at post-intervention. We performed an intention-to-treat analysis using repetitive measures and multilevel regression analyses.

RESULTS

We found a significant reduction in suicidal ideation (b=-6.7, p = 0.015, Cohen´s d = 0.49), depressive (b=-3.1, p = 0.002, Cohen´s d = 0.81) and anxiety (b=-2.60, p < 0.001, Cohen´s d = 0.72) symptoms, and hopelessness (b=-3.7, p < 0.001, Cohen´s d = 0.70) in the intervention group compared to the control group at post-intervention. We also found improvement in solving-problems skills (b=-1.6, p = 0.002, Cohen´s d = 0.58), behavioral activation (b = 2.8, p = 0.019, Cohen´s d = 0.47), and cognitive reappraisal (b = 2.2, p = 0.029, Cohen´s d = 0.53). In the exploration of the intervention mechanisms concerning suicidal ideation, the total indirect effect of the intervention (b = -5.727923; p = 0.008) was significant, whereas the direct effect (b = - 0.03195473, p = 0.903) was not significant (Suppl 2, Table 1). Problem-solving skill (b=-2.84, p = 0.016) was a significant mediator of intervention effects on suicidal ideation (Path a*b).

CONCLUSIONS

This is the first clustered RCT evaluation of the effectiveness of a blended indicated intervention to prevent suicidality in school settings in Latin America. This is the first step to informing policymakers to scale up an effective intervention for an important public health problem.

Prevention of self-harm and suicide in young people up to the age of 25 in education settings

BACKGROUND

In 2016, globally, suicide was the second leading cause of death amongst those aged 15 to 29 years. Self-harm is increasingly common among young people in many countries, particularly among women and girls. The risk of suicide is elevated 30-fold in the year following hospital presentation for self-harm, and those with suicidal ideation have double the risk of suicide compared with the general population. Self-harm and suicide in young people are significant public health issues that cause distress for young people, their peers, and family, and lead to substantial healthcare costs. Educational settings are widely acknowledged as a logical and appropriate place to provide prevention and treatment. A comprehensive, high-quality systematic review of self-harm and suicide prevention programmes in all education settings is thus urgently required. This will support evidence-informed decision making to facilitate rational investment in prevention efforts in educational settings. Suicide and self-harm are distressing, and we acknowledge that the content of this review is sensitive as the data outlined below represents the lived and living experience of suicidal distress for individuals and their caregivers.

OBJECTIVES

To assess the effects of interventions delivered in educational settings to prevent or address self-harm and suicidal ideation in young people (up to the age of 25) and examine whether the relative effects on self-harm and suicide are modified by education setting.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Specialised Register, CENTRAL, The Cochrane Database of Systematic Reviews, Ovid MEDLINE, PsycINFO, ERIC, Web of Science Social Science Citation Index, EBSCO host Australian Education Index, British Education Index, Educational Research Abstracts to 28 April 2023.

SELECTION CRITERIA

We included trials where the primary aim was to evaluate an intervention specifically designed to reduce self-harm or prevent suicide in an education setting. Randomised controlled trials (RCTs), cluster-RCTs, cross-over trials and quasi-randomised trials were eligible for inclusion. Primary outcomes were self-harm postintervention and acceptability; secondary outcomes included suicidal ideation, hopelessness, and two outcomes co-designed with young people: better or more coping skills, and a safe environment, with more acceptance and understanding.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane. Two review authors independently selected studies, extracted data, and assessed risk of bias. We analysed dichotomous data as odds ratios (ORs) and continuous data as standardised mean differences (SMDs) with 95% confidence intervals (CIs). We conducted random-effects meta-analyses and assessed certainty of evidence using the GRADE approach. For co-designed outcomes, we used vote counting based on the direction of effect, as there is a huge variation in the data and the effect measure used in the included studies.

MAIN RESULTS

We included 51 trials involving 36,414 participants (minimum 23; maximum 11,100). Twenty-seven studies were conducted in secondary schools, one in middle school, one in primary school, 19 in universities, one in medical school, and one across education and community settings. Eighteen trials investigated universal interventions, 11 of which provided data for at least one meta-analysis, but no trials provided data for self-harm postintervention. Evidence on the acceptability of universal interventions is of very low certainty, and indicates little or no difference between groups (OR 0.77, 95% CI 0.36 to 1.67; 9 studies, 8528 participants). Low-certainty evidence showed little to no effect on suicidal ideation (SMD -0.02, 95% CI -0.23 to 0.20; 4 studies, 379 participants) nor on hopelessness (MD -0.01, 95% CI -1.98 to 1.96; 1 trial, 121 participants). Fifteen trials investigated selective interventions, eight of which provided data for at least one meta-analysis, but only one trial provided data for self-harm postintervention. Low-certainty evidence indicates that selective interventions may reduce self-harm postintervention slightly (OR 0.39, 95% CI 0.06 to 2.43; 1 trial, 148 participants). While no trial provided data for hopelessness, little to no effect was found on acceptability (OR 1.00, 95% CI 0.5 to 2.0; 6 studies, 10,208 participants; very low-certainty evidence) or suicidal ideation (SMD 0.04, 95% CI -0.36 to 0.43; 2 studies, 102 participants; low-certainty evidence). Seventeen trials investigated indicated interventions, 14 of which provided data for at least one meta-analysis, but only four trials provided data for self-harm postintervention and two reported no events in both groups. Low-certainty evidence suggests that indicated interventions may slightly reduce self-harm postintervention (OR 0.19, 95% CI 0.02 to 1.76; 2 studies, 76 participants). There is also low-certainty evidence indicating that these interventions may decrease the odds of non-suicidal self-injury (OR 0.65, 95% CI 0.24 to 1.79; 2 studies, 89 participants). Evidence of a slight decrease in acceptability in the intervention group is of low certainty (OR 1.44, 95% CI 0.86 to 2.42; 10 studies, 641 participants). Low-certainty evidence shows that indicated interventions may slightly reduce suicidal ideation (SMD -0.33, 95% CI -0.55 to -0.10; 10 studies, 685 participants) and may result in little to no difference in hopelessness postintervention (SMD -0.27, 95% CI -0.55 to 0.01; 6 studies, 455 participants). There were mixed findings regarding the effect of suicide prevention interventions on a range of constructs relevant to coping skills and safe environment. None of the trials, however, measured the impact of improvements in these constructs on self-harm or suicidal ideation.

AUTHORS' CONCLUSIONS

While this review provides an update on the evidence about interventions targeting self-harm and suicide prevention in education settings, there remains significant uncertainty about the impact of these interventions. There are some promising findings but large replication studies are needed, as are studies that examine the combination of different intervention approaches, and can be delivered in a safe environment and implemented over a long period of time. Further research is required to understand and measure outcomes that are meaningful to young people with lived experience, as they want coping skills and safety of the environment in which they conduct their everyday lives to be measured as key outcomes in future trials.

Psychological interventions for suicidal behavior in adolescents: a comprehensive systematic review

BACKGROUND

Recent evidence indicates that the risk of death by suicide in teenagers has increased significantly worldwide. Consequently, different therapeutic interventions have been proposed for suicidal behavior in this particular population. Therefore, the main objective of this study is to provide an updated review of the existing psychological interventions for the treatment of suicide attempts (SA) in adolescents and to analyze the efficacy of such interventions.

METHODS

A systematic review was conducted following PRISMA guidelines. The studies were identified by searching PubMed, PsychINFO, Web of Science, and Scopus databases from 2016 to 2022. According to the inclusion criteria, a total of 40 studies that tested the efficacy of different psychological interventions were selected.

RESULTS

Various psychological interventions for adolescents with suicidal behaviors were identified. Most of those present promising results. However, to summarize results from recent years, dialectical behavior therapy (DBT) was the most common and the only treatment shown to be effective for adolescents at high risk of suicide and SA. In contrast, empirical evidence for other psychological interventions focusing on deliberate self-harm (SH) is inconclusive.

CONCLUSIONS

Interventions specifically designed to reduce suicidal risk in adolescents have multiplied significantly in recent years. There are a few promising interventions for reducing suicidal behaviors in adolescents evaluated by independent research groups. However, replication and dismantling studies are needed to identify the effects of these interventions and their specific components. An important future challenge is to develop brief and effective interventions to reduce the risk of death by suicide among the adolescent population.

Public health measures related to the transmissibility of suicide

Transmission is an important concept in suicide prevention. It can occur when exposure to another person's death by suicide (or to suicide-related information more generally) draws attention to suicide or highlights specific suicide methods. In this paper, the fourth in a Series on a public health approach to suicide prevention, we contend that the transmissibility of suicide must be considered when determining optimal ways to address it. We draw on five examples of how transmission might occur and be prevented. The first two examples relate to transmission initiated by representations of suicide in traditional and new media. The third concerns transmission that leads to suicide clusters, and the fourth considers a specific setting in which transmission occurs, namely secondary schools. Finally, we discuss how suicide risk might be countered by the transmission of suicide prevention messages in media campaigns.

Study protocol for the Multimodal Approach to Preventing Suicide in Schools (MAPSS) project: A regionally based feasibility trial of an integrated response to suicide risk among UK secondary school pupils

BACKGROUND

Suicide is the leading cause of death of children and young people under 35 in the UK, and suicide rates are rising in this age group. Schools are considered an appropriate and logical setting for youth suicide prevention activities, with universal, selective, and indicated approaches all demonstrating efficacy. Given that international best practice recommends suicide prevention programmes combine these approaches, and that to date this has not been done in school settings in the UK, this study aims to evaluate the feasibility of delivering a suicide prevention programme incorporating universal, selective, and indicated components in UK schools.

METHODS

This study is a feasibility cluster-randomised controlled trial (RCT) of an adapted version of the Multimodal Approach to Preventing Suicide in Schools (MAPSS) programme. The programme, initially developed in Australia, involves delivering universal psychoeducation to all pupils, screening them for suicide risk, and delivering Internet-based Cognitive Behavioural Therapy (Reframe IT-UK) to those students identified as being at high-risk for suicide. The programme will be trialled in six secondary schools in Northwest England and will target Year 10 students (14- and 15-year-olds). The primary aims are to assess: 1) the acceptability and safety of delivering MAPSS in a school setting in the UK; 2) the social validity of the MAPSS programme; and 3) the feasibility of delivering a large-scale, appropriately powered, cluster-RCT and economic evaluation of this intervention in the future. Secondary aims are to assess changes over time in mental health and wellbeing outcomes.

DISCUSSION

This study is the first to evaluate a suicide prevention programme comprising universal, selective, and indicated components in UK schools. If the programme is found to be feasible, it could be more widely tested in schools and may ultimately lead to reduced rates of suicide and suicidal behaviour in young people.

Preliminary Effectiveness of a Therapist-Supported Digital Mental Health Intervention in Reducing Suicidal Ideation

Suicidal ideation (SI) is a significant public health concern with increasing prevalence. Therapist-supported digital mental health interventions (DMHI) are an emergent modality to address common mental health problems like depression and anxiety, although less is known about SI. This study examined SI trajectories among 778 patients who participated in a therapist-supported DMHI using multilevel models during and up to 6-months post-treatment. Estimates of associated suicide attempts and deaths by suicide were calculated using published data linking PHQ-9-assessed SI to records of suicide attempts and deaths by suicide. The proportion of participants reporting no SI significantly increased between baseline and end-of-treatment (78.02% to 91.00%). Effect sizes of SI changes between baseline and end-of-treatment, 3-month, and 6-month follow-ups were 0.33 (95%CI = 0.27-0.38), 0.32 (95%CI = 0.27-0.38), and 0.32 (95%CI = 0.27-0.38), respectively. Results also indicated an estimated 30.49% reduction (95%CI = 25.15%-35.13%) in suicide attempts and death by suicide across treatment. This study provides preliminary evidence of the effectiveness of a therapist-supported DMHI in reducing SI.

Effectiveness of internet-delivered psychological treatments for children and adolescents with anxiety and/or depressive disorders: Systematic review and network meta-analysis

Background

Anxiety and depression symptomatology has increased in the child and adolescent population. Internet-delivered psychological treatments (IDPT) can help to reduce this symptomatology, attending to the largest possible population.

Aim

To conduct a systematic review and network meta-analysis of IDPT to reduce anxiety and depression symptoms in children and adolescents.

Methods

The search for studies was conducted in SCOPUS, PsycINFO, PSICODOC, PsycARTICLES and Medline, between 2000 and 2022, in December 2022. Studies were selected if they were conducted with a sample of children and/or adolescents with previous symptoms of anxiety and depression, had applied IDPT, and included at least two comparative groups with pretest-posttest measures. Network meta-analyses were separately performed for anxiety and depression outcomes. Publication bias was analyzed using Egger's test and funnel plots, and mixed-effects meta-regression models were applied to account for heterogeneity.

Results

37 studies were included in the meta-analysis, providing a total of 74 comparative groups. IDPT exhibited low-to-moderate, statistically significant average effect sizes when compared to both inactive and active controls. No statistical significance was found when IDPT was compared with other types of interventions.

Discussion

IDPT is recommended to reduce anxiety and depression symptomatology in children and adolescents, but more studies are needed which compare treatments with other types of interventions, such as face-to-face therapy.

Non-pharmacological interventions for preventing suicide attempts: A systematic review and network meta-analysis

Suicide attempts can cause serious physical harm or death. It would be crucial to gain a better understanding of the comparative efficacy of non-pharmacological interventions. We aimed to identify which non-pharmacological interventions are more effective in preventing suicide attempts. PubMed, Web of Science, and EMBASE databases were searched systematically from their inception until 3 April 2023. To be eligible for inclusion, randomized controlled trials (RCTs) had to meet the following criteria: Participants were individuals who had suicidal ideation or a history of severe self-harm or attempted suicide. A network meta-analysis was performed using a random effects model to estimate the treatment effect of various non-pharmacological interventions. (PROSPERO registration number: CRD42023411393). We obtained data from 54 studies involving 17,630 participants. Our primary analysis found that Cognitive therapy (CT) (OR=0.19, 95%CI =0.04-0.81), Dialectical Behavior Therapy (DBT) (OR=0.37, 95%CI =0.13-0.97), Cognitive-behavioral therapy (CBT) (OR=0.42, 95%CI =0.17-0.99), and Brief intervention and contact (BIC) (OR=0.65, 95%CI=0.44-0.94) were superior to TAU (within the longest available follow-up time) in preventing suicide attempts, while other intervention methods do not show significant advantages over TAU. Secondary analysis showed that the two intervention measures (CT and BIC) were effective when follow-up time did not exceed 6 months, but there was no effective intervention measure with longer follow-up times. CT, DBT, CBT, and BIC have a better effect in preventing suicide attempts than other non-pharmacological interventions. Additional research is necessary to validate which interventions, as well as which combinations of interventions, are the most effective.

Cognitive Behavioral Therapy Approaches for Chronic Suicidality

This review provides an overview of research evidence from the past 5 years concerning cognitive behavioral therapy for suicide prevention. The authors then discuss the clinical implementation of this approach in patients with chronic suicidal behavior.

Prevalence of Suicidal Behavior Among Students in South-East Asia: A Systematic Review and Meta-Analysis

OBJECTIVES

Estimation of rates of suicidal behaviors (ideation, plan, and attempt) would help to understand the burden and prioritize prevention strategies. However, no attempt to assess suicidal behavior among students was identified in South-East Asia (SEA). We aimed to assess the prevalence of suicidal behavior (ideation, plan, and attempt) among students in SEA.

METHODS

We followed PRISMA 2020 guidelines and registered the protocol in PROSPERO (CRD42022353438). We searched in Medline, Embase, and PsycINFO and performed meta-analyses to pool the lifetime, 1-year, and point prevalence rates for suicidal ideation, plans, and attempts. We considered the duration of a month for point prevalence.

RESULTS

The search identified 40 separate populations from which 46 were included in the analyses, as some studies included samples from multiple countries. The pooled prevalence of suicidal ideation was 17.4% (confidence interval [95% CI], 12.4%-23.9%) for lifetime, 9.33% (95% CI, 7.2%-12%) for the past year, and 4.8% (95% CI, 3.6%-6.4%) for the present time. The pooled prevalence of suicide plans was 9% (95% CI, 6.2%-12.9%) for lifetime, 7.3% (95% CI, 5.1%-10.3%) for the past year, and 2.3% (95% CI, 0.8%-6.7%) for the present time. The pooled prevalence of suicide attempts was 5.2% (95% CI, 3.5%-7.8%) for lifetime and 4.5% (95% CI, 3.4%-5.8%) for the past year. Higher rates of suicide attempts in the lifetime were noted in Nepal (10%) and Bangladesh (9%), while lower rates were reported in India (4%) and Indonesia (5%).

CONCLUSIONS

Suicidal behaviors are a common phenomenon among students in the SEA region. These findings call for integrated, multisectoral efforts to prevent suicidal behaviors in this group.

Exploring the Safety of a General Digital Mental Health Intervention to Effect Symptom Reduction among Individuals with and without Suicidal Ideation: A Secondary Analysis

Trials of digital mental health interventions (DMHIs) often exclude individuals with suicide-related thoughts and behaviors precluding an understanding of whether DMHIs for affective disorders are safe for, and perform similarly within, this high-risk group. We explore the safety and performance of a DMHI for depression in participants with and without suicidal ideation (SI) at baseline. Three hundred and one participants were included in this secondary data analysis from a trial of an 8-week DMHI comprising 14 smartphone apps. We found that SI decreased across the study among participants with baseline SI and that baseline SI status did not attenuate depression treatment effects. Through a case study of the IntelliCare platform, we find that DMHIs for general affective disorders can be safe.

A meta-analysis of targeted interventions for reducing suicide-related behaviour and ideation in adolescents: Implications for trial design

INTRODUCTION

Suicidality among young people is a significant societal issue. The current study conducted a meta-analysis of community and clinical interventions targeting suicide attempts, self-harm, and suicidal ideation in adolescents.

METHODS

Interventions targeting suicide attempts, self-harm and suicidal ideation were identified by searching PsychINFO, Medline, CINAHL and Embase in line with the PRISMA statement. Study quality was determined using a risk of bias tool. Meta-analyses examined the efficacy of the interventions. Effect sizes were calculated for suicidal ideation data (continuous data) using Hedge's g for standardised mean differences. Suicide attempts and self-harm (dichotomous data) were calculated using odds ratios (ORs).

RESULTS

Seventeen RCTs were included in the meta-analysis. No significant differences were found between treatment and control groups on measures of suicide attempts or self-harm. A small effect-size was observed on measures of suicidal ideation (g = 0.47). A secondary meta-analysis investigated change over time in treatment as usual conditions, finding significant large effect-sizes for suicide attempts (OR = 18.67), self-harm (OR = 12.77), and suicidal ideation (g = 0.86).

LIMITATIONS

The methodological decision to focus on specific outcomes over a broad definition of self-harm excluded some papers, which have been included in other reviews. It is unlikely to have significantly affected the overall results. The review was not preregistered.

CONCLUSIONS

These twin findings highlight the importance overcoming the methodological difficulty of discerning effective interventions during a period of baseline improvement. We suggest that future trials should move away from broadly addressing "suicidality/self-harm" and encourage a greater targeting of at-risk individuals.

Improving Suicide Prevention Through Evidence-Based Strategies: A Systematic Review

Objective

The authors sought to identify scalable evidence-based suicide prevention strategies.

Methods

A search of PubMed and Google Scholar identi- fied 20,234 articles published between September 2005 and December 2019, of which 97 were randomized controlled trials with suicidal behavior or ideation as primary outcomes or epidemiological studies of limiting access to lethal means, using educational approaches, and the impact of antidepressant treatment.

Results

Training primary care physicians in depression rec- ognition and treatment prevents suicide. Educating youths on depression and suicidal behavior, as well as active out- reach to psychiatric patients after discharge or a suicidal crisis, prevents suicidal behavior. Meta-analyses find that antidepressants prevent suicide attempts, but individual randomized controlled trials appear to be underpowered. Ketamine reduces suicidal ideation in hours but is untested for suicidal behavior prevention. Cognitive-behavioral therapy and dialectical behavior therapy prevent suicidal behavior. Active screening for suicidal ideation or behavior is not proven to be better than just screening for depression. Education of gatekeepers about youth suicidal behavior lacks effectiveness. No randomized trials have been reported for gatekeeper training for prevention of adult suicidal behavior. Algorithm-driven electronic health record screening, Internet-based screening, and smartphone passive monitoring to identify high-risk patients are under-studied. Means restriction, including of firearms, prevents suicide but is sporadically employed in the United States, even though firearms are used in half of all U.S. suicides.

Conclusions

Training general practitioners warrants wider implementation and testing in other nonpsychiatrist physi- cian settings. Active follow-up of patients after discharge or a suicide-related crisis should be routine, and restricting firearm access by at-risk individuals warrants wider use. Combination approaches in health care systems show promise in reducing suicide in several countries, but evaluating the benefit attributable to each component is essential. Further suicide rate reduction requires evaluating newer approaches, such as electronic health record-derived algorithms, Internet-based screening methods, ketamine's potential benefit for preventing attempts, and passive monitoring of acute suicide risk change.Reprinted from Am J Psychiatry 2021; 178:611-624, with permission from American Psychiatric Association Publishing.

Acceptability and Feasibility of "Village," a Digital Communication App for Young People Experiencing Low Mood, Thoughts of Self-harm, and Suicidal Ideation to Obtain Support From Family and Friends: Mixed Methods Pilot Open Trial

BACKGROUND

Young people experiencing low mood, thoughts related to self-harm, and suicidal ideation often struggle to communicate their emotions and receive timely support from family and friends. Technologically delivered support interventions may be useful in addressing this need.

OBJECTIVE

This paper aimed to evaluate the acceptability and feasibility of "Village," a communication app co-designed with young people and their family and friends from New Zealand.

METHODS

A mixed methods pilot open trial design was adopted. Participants were primarily recruited via social media advertisements and clinicians in specialist mental health services over an 8-month period. The primary outcomes were acceptability of the app (via thematically analyzed qualitative feedback and retention rates) and feasibility of conducting a larger randomized controlled trial gauged via effectiveness of recruitment methods, completion of chosen outcome measures, and occurrence of unanticipated operational issues. Secondary outcomes were app usability, safety, and changes in symptoms of depression (via the Patient Health Questionnaire-9 modified for adolescents), suicidal ideation (on the Suicidal Ideation Questionnaire), and functioning (using the World Health Organization Disability Assessment Schedule 2.0 or Child and Youth version).

RESULTS

A total of 26 young people ("users") were enrolled in the trial, of which 21 recruited friends and family members ("buddies") and completed quantitative outcome measures at baseline, 4 weeks, and 3 months. Furthermore, 13 users and 12 buddies also provided qualitative feedback about the app, identifying the key themes of appeal of app features and layout, usefulness of its content, and technological challenges (primarily with onboarding and notifications). Users gave Village a mean rating of 3.8 (range 2.7-4.6) out of 5 on a 5-point scale for app quality and an overall star rating of 3.4 out of 5 for subjective quality. Within this limited sample, users reported a clinically significant reduction in depressive symptoms (P=.007), but nonsignificant changes in suicidal ideation and functioning. The embedded risk detection software was activated on 3 occasions, and no additional support was required for users.

CONCLUSIONS

During this open trial, Village was found to be acceptable, usable, and safe. The feasibility of a larger randomized controlled trial was also confirmed after some modifications to the recruitment strategy and app.

IMPACT: Evaluation of a Controlled Organizational Intervention Using Influential Peers to Promote Professional Fulfillment

OBJECTIVE

To determine the effects of a popular opinion leader (POL)-led organizational intervention targeting all physicians and advanced practice providers (APPs) working within clinic groups on professional fulfillment (primary outcome), gratitude, burnout, self-valuation, and turnover intent.

PATIENTS AND METHODS

All 20 Stanford University HealthCare Alliance clinics with ≥5 physicians-APPs were matched by size and baseline gratitude scores and randomly assigned to immediate or delayed intervention (control). Between July 10, 2018, and March 15, 2019, trained POLs and a physician-PhD study investigator facilitated 4 interactive breakfast or lunch workshops at intervention clinics, where colleagues were invited to discuss and experience one evidence-based practice (gratitude, mindfulness, cognitive, and behavioral strategies). Participants in both groups completed incentivized annual assessments of professional fulfillment, workplace gratitude, burnout, self-valuation, and intent to leave as part of ongoing organizational program evaluation.

RESULTS

Eighty-four (75%) physicians-APPs at intervention clinics attended at least 1 workshop. Of all physicians-APPs, 236 of 251 (94%) completed assessments in 2018 and 254 of 263 (97%) in 2019. Of 264 physicians-APPs with 2018 or 2019 assessment data, 222 (84%) had completed 2017 assessments. Modal characteristics were 60% female, 46% White, 49% aged 40 to 59 years, 44% practicing family-internal medicine, 78% living with partners, and 53% with children. Change in professional fulfillment by 2019 relative to average 2017 to 2018 levels was more favorable (0.63 points; effect size = 0.35; P=.001) as were changes in gratitude and intent to leave among clinicians practicing at intervention clinics.

CONCLUSION

Interventions led by respected physicians-APPs can achieve high participation rates and have potential to promote well-being among their colleagues.

Utilisation of Digital Applications for Personal Recovery Amongst Youth with Mental Health Concerns

There is an increasing population of youths that report mental health issues. Research has shown that youths are reluctant to seek help for various reasons. A majority of those who do seek help are using digital mental health supports. Subsequently, efforts to promote youth mental health have focused on the use of digital applications as a means of overcoming barriers related to factors including stigma and lack of available services. The worldwide move toward recovery-oriented care led to emerging research on personal recovery amongst youths with mental health concerns. This study sought to address the need for recovery-oriented digital resources for youths. It utilised a qualitative design methodology to develop a rich interpretation of how youths are using digital interventions to support their mental health recovery journey. It sought to understand how existing digital applications are useful for youth recovery and identified characteristics associated with recovery and engagement. The content analysis generated five categories that represent facilitators of youth recovery and the thematic analysis identified key elements of digital applications that support youth recovery. The results offer complimentary support and guidance for recovery-oriented care and the use of digital mental health interventions in the promotion of personal recovery amongst youths.

Does loneliness affect how young adults engage with and benefit from a smartphone intervention targeting suicidal ideation?: Randomised Controlled Trial (Preprint)

BACKGROUND

Loneliness is commonly reported by young people and has been shown to contribute to the rapid onset and escalation of depression and suicidal ideation during adolescence. Lonely people may also be particularly susceptible to disengaging from treatment early given the likelihood of their more complex clinical profiles leading to cognitive fatigue. While a smartphone intervention (LifeBuoy) has been shown to effectively reduce suicidal ideation in young adults, poor engagement is a well-documented issue for this therapeutic modality and has been shown to result in poorer treatment outcomes.

OBJECTIVE

This study aims to determine whether loneliness affects how young people experiencing suicidal ideation engage with and benefit from a therapeutic smartphone intervention (LifeBuoy).

METHODS

A total of 455 community-based Australian young adults (aged 18-25 years) experiencing recent suicidal ideation were randomized to use a dialectical behavioral therapy-based smartphone intervention (LifeBuoy) or an attention-matched control app (LifeBuoy-C) for 6 weeks. Participants completed measures of suicidal ideation, depression, anxiety, and loneliness at baseline (T0), post intervention (T1), and 3 months post intervention (T2). Piecewise linear mixed models were used to examine whether loneliness levels moderated the effect of LifeBuoy and LifeBuoy-C on suicidal ideation and depression across time (T0 to T1; T1 to T2). This statistical method was then used to examine whether app engagement (number of modules completed) influenced the relationship between baseline loneliness and suicidal ideation and depression across time.

RESULTS

Loneliness was positively associated with higher levels of overall suicidal ideation (B=0.75, 95% CI 0.08-1.42; P=.03) and depression (B=0.88, 95% CI 0.45-1.32; P<.001), regardless of time point or allocated condition. However, loneliness did not affect suicidal ideation scores across time (time 1: B=1.10, 95% CI -0.25 to 2.46; P=.11; time 2: B=0.43, 95% CI -1.25 to 2.12; P=.61) and depression scores across time (time 1: B=0.00, 95% CI -0.67 to 0.66; P=.99; time 2: B=0.41, 95% CI -0.37 to 1.18; P=.30) in either condition. Similarly, engagement with the LifeBuoy app was not found to moderate the impact of loneliness on suicidal ideation (B=0.00, 95% CI -0.17 to 0.18; P=.98) or depression (B=-0.08, 95% CI -0.19 to 0.03; P=.14).

CONCLUSIONS

Loneliness was not found to affect young adults' engagement with a smartphone intervention (LifeBuoy) nor any clinical benefits derived from the intervention. LifeBuoy, in its current form, can effectively engage and treat individuals regardless of how lonely they may be.

Protocol for a randomised controlled trial evaluating the effectiveness of a CBT-based smartphone application for improving mental health outcomes in adolescents: the MobiliseMe study

BACKGROUND

Depression is a leading cause of disability in adolescents, however few receive evidence-based treatment. Despite having the potential to overcome barriers to treatment uptake and adherence, there are very few CBT-based smartphone apps for adolescents. To address this gap, we developed ClearlyMe®, a self-guided CBT smartphone app for adolescent depression and anxiety. ClearlyMe® consists of 37 brief lessons containing core CBT elements, accessed either individually or as part of a 'collection'. Here, we describe the protocol for a randomised controlled trial aiming to evaluate the effect of ClearlyMe® on depressive symptoms and secondary outcomes, including engagement, anxiety and wellbeing, when delivered with and without guided support compared to an attention matched control.

METHODS

We aim to recruit 489 adolescents aged 12-17 years with mild to moderately-severe depressive symptoms. Participants will be screened for inclusion, complete the baseline assessment and are then randomly allocated to receive ClearlyMe® (self-directed use), ClearlyMe® with guided SMS support (guided use) or digital psychoeducation (attention-matched control). Depressive symptoms and secondary outcomes will be assessed at 6-weeks (primary endpoint) and 4-months post-baseline (secondary endpoint). Engagement, conceptualised as uptake, adherence and completion, will also be assessed 6-weeks post-baseline. Mixed-effects linear modelling will be used to conduct intention-to-treat analyses to determine whether reductions in depressive symptoms and secondary outcomes are greater for conditions receiving ClearlyMe® relative to control at 6-weeks and 4-months post-baseline and greater for intervention adherers relative to non-adherers. To minimise risk, participants will be encouraged to use the Get Help section of the app and can also opt to receive a call from the team clinical psychologist at baseline, and at the 6-week and 4-month post-baseline assessments when reporting suicidal ideation.

DISCUSSION

This is the first clinical trial examining a CBT smartphone app specifically designed for adolescent depression. It will provide empirical evidence on the effects of ClearlyMe® on depressive symptoms when used with and without guided support.

Internet-based interventions to support recovery in youth: A systematic review

Personal recovery represents a paradigm shift in how individuals are seen to benefit from mental health interventions, from a narrow view of symptom reduction to a holistic, multi-dimensional view of well-being, functional gains and rehabilitation. Although there is a large body of evidence supporting the use of recovery-oriented care in adults, research on personal recovery amongst youth with mental health concerns is an emerging area of research. Efforts to promote youth mental health have also focussed on the use of digital applications and platforms as a means of overcoming barriers related to factors including stigma and lack of available services. This systematic review aims to review the literature on existing internet-based, youth mental health interventions with regard to (a) identifying elements of the programs that align with the personal recovery and (b) outcome measures utilised in assessing personal recovery. Eleven papers were identified that met the inclusion criteria. Five of the programs reviewed from these eleven papers showed efficacy for recovery processes. The results offer preliminary support and guidance for the use of internet-based mental health interventions in the promotion of personal recovery amongst youth. Future research and practice are suggested to further develop understanding in this area.

Interventions for attempted suicide

PURPOSE OF REVIEW

Suicide is a major, global, public health issue. Those who attempt suicide represent a high-risk subgroup for eventual death by suicide. We provide an update on emerging evidence for interventions for attempted suicide to reduce subsequent suicidal behavior.

RECENT FINDINGS

Major approaches that have been examined recently include pharmacological, psychosocial, brief active contact and outreach interventions, and digitally driven interventions. Notwithstanding the limited evidence base for most of these approaches, brief contact and follow-up interventions appear to have more robust effects on reduction of repeat suicidal behavior, including attempts; such approaches may have especial significance in emergency settings because of their brevity. Digital interventions for self-harm appear promising in the short-term whereas the evidence for pharmacological and psychosocial strategies remain inconclusive.

SUMMARY

Although current evidence supports the use of brief interventions, contact, and outreach for reducing risk of subsequent suicide attempts and suicidal behavior, there are large gaps and limitations in the evidence base related to trial design, lack of long-term efficacy data, and implementational challenges. More robustly designed long-term trials that examine integrated intervention approaches with well defined outcomes are needed to develop recommendations in this area.

Effectiveness of distance-based suicide interventions: multi-level meta-analysis and systematic review

BACKGROUND

The use of distance-based interventions (DBIs) to reduce suicidal ideation and behaviours are an increasingly relevant form of intervention. DBIs are more affordable, scalable and available than traditional face-to-face interventions, helping to narrow the gap between needed and provided care.

AIMS

To evaluate the overall effectiveness of DBIs against suicidal ideation and behaviours.

METHOD

We systematically searched Web of Science, Scopus and PubMed for all DBIs primarily aimed at reducing suicidal ideation and behaviours. Data were analysed with a robust variance estimation corrected, multi-level meta-analysis.

RESULTS

We found 38 studies, reporting 110 outcomes. Effectiveness in reducing suicidal ideation was low (standardised mean difference -0.174, 95% CI -0.238 to -0.110). DBIs were significantly less effective against suicidal behaviours than against suicidal ideation, although still effective (standardised mean difference -0.059, 95% CI -0.087 to -0.032). Human involvement had no significant effect on effectiveness.

CONCLUSIONS

Despite low effectiveness, DBIs might play a role in large-scale prevention efforts against suicidal ideation within a stepped care approach. Further, DBIs may be helpful in expanding mental health services in low- and middle-income countries with otherwise limited access to mental healthcare. Although the evidence for DBIs efficacy is well grounded, the technical and scientific evaluation of DBIs regarding their set up, functionality and components needs to be addressed in future studies.

Effectiveness of Digital Health Interventions on Unintentional Injury, Violence, and Suicide: Meta-Analysis

Digital technologies are increasingly used in health-care delivery and are being introduced into work to prevent unintentional injury, violence, and suicide to reduce mortality. To understand the potential of digital health interventions (DHIs) to prevent and reduce these problems, we conduct a meta-analysis and provide an overview of their effectiveness and characteristics related to the effects. We searched electronic databases and reference lists of relevant reviews to identify randomized controlled trials (RCTs) published in or before March 2020 evaluating DHIs on injury, violence, or suicide reduction. Based on the 34 RCT studies included in the meta-analysis, the overall random effect size was 0.21, and the effect sizes for reducing suicidal ideation, interpersonal violence, and unintentional injury were 0.17, 0.24, and 0.31, respectively, which can be regarded as comparable to the effect sizes of traditional face-to-face interventions. However, there was considerable heterogeneity between the studies. In conclusion, DHIs have great potential to reduce unintentional injury, violence, and suicide. Future research should explore DHIs' successful components to facilitate future implementation and wider access.

Rates and Predictors of Deterioration in a Trial of Internet-Delivered Cognitive Behavioral Therapy for Reducing Suicidal Thoughts

OBJECTIVE

It is necessary for suicide prevention interventions to demonstrate safety. One important aspect of safety is evidence that deterioration rates are low. No studies have examined deterioration of suicidal ideation in the context of an internet-based cognitive behavioral therapy (CBT) intervention to reduce suicidal ideation. A secondary analysis of the outcomes of an online trial was conducted to determine rates of deterioration in a CBT intervention called Living with Deadly Thoughts, relative to an attention control condition, and to identify factors associated with deterioration.

METHOD

The randomized controlled trial included 418 adults with suicidal ideation at baseline (77% females, mean age 40.6 years). Deterioration was defined in two ways: a reliable increase in Suicidal Ideation Attributes Scale (SIDAS score) of ≥6.0 units; or triggering the safety protocol during the trial as determined by high levels of suicidality. Analyses were repeated with multiply imputed data. Predictors of deterioration were identified using logistic regression analysis.

RESULTS

30 (14%) participants in the control group and 15 (7%) in the intervention group met criteria for reliable deterioration (Fisher's exact p = 0.027). In a fully adjusted logistic regression model, greater initial severity of suicidal thinking was associated with lower odds of deterioration, while intervention condition, demographics, psychological factors and mental health factors had no significant association with deterioration.

CONCLUSIONS

Participation in an online suicide prevention intervention was associated with lower prevalence of reliable deterioration than participation in an attention-control intervention, providing further evidence that internet-based CBT interventions do not cause harm.HighlightsFirst study to assess deterioration in an internet suicide prevention interventionRates of reliable deterioration were higher in control (14%) than intervention (7%)No psychological or demographic factors were robustly associated with deteriorationFindings provide further evidence that internet based CBT programs are not harmful.

Testing the Effectiveness of a Blended Intervention to Reduce Suicidal Ideation among School Adolescents in Chile: A Protocol for a Cluster Randomized Controlled Trial

Suicidal ideation is prevalent in adolescents and is a marker for subsequent psychiatric vulnerability and symptom severity. Literature shows that blended care (integrating online and offline components in a treatment process) could improve the effectiveness and adherence of interventions targeting suicidal ideation in adolescents, but the evidence is inconclusive. Thus, we will test the effectiveness of a blended intervention to reduce suicidal ideation (primary outcome) in school settings using a single-blind two-armed cluster randomized controlled trial (cRCT). The internet-based component corresponds to the Reframe-IT, a program encompassing eight online sessions based on cognitive-behavioral therapy (CBT) principles. The face-to-face intervention will be delivered through four CBT sessions. Additionally, we will assess the effect of the intervention on the following secondary outcomes: suicidal attempts, depressive symptoms, hopelessness, emotional regulation, and problem-solving skills. Primary and secondary outcomes will be assessed at post-intervention, 3-month, 6-month, and 12-month follow-up. Finally, we will explore the mediation role of cognitive, emotional, and behavioral correlates of suicide on the effect of the intervention. Results will inform whether the intervention can reduce suicide among school adolescents and be implemented on a large scale in Chile.

Study protocol for the Multimodal Approach to Preventing Suicide in Schools (MAPSS) project: a regionally based randomised trial of an integrated response to suicide risk among secondary school students

BACKGROUND

Suicide is the leading cause of death among young Australians, accounting for one-third of all deaths in those under 25. Schools are a logical setting for youth suicide prevention activities, with universal, selective and indicated approaches all demonstrating efficacy. Given that international best practice recommends suicide prevention programmes combine these approaches, and that to date this has not been done in school settings, this study aims to evaluate a suicide prevention programme incorporating universal, selective and indicated components in schools.

METHODS

This study is a trial of a multimodal suicide prevention programme for young people. The programme involves delivering universal psychoeducation (safeTALK) to all students, screening them for suicide risk, and delivering internet-based Cognitive Behavioural Therapy (Reframe IT) to those students identified as being at high risk for suicide. The programme will be trialled in secondary schools in Melbourne, Australia, and target year 10 students (15 and 16 year-olds). safeTALK and screening will be evaluated using a single group pre-test/post-test case series, and Reframe IT will be evaluated in a Randomised Controlled Trial. The primary outcome is change in suicidal ideation; other outcomes include help-seeking behaviour and intentions, and suicide knowledge and stigma. The programme's cost-effectiveness will also be evaluated.

DISCUSSION

This study is the first to evaluate a suicide prevention programme comprising universal, selective and indicated components in Australian schools. If the programme is found to be efficacious and cost-effective, it could be more widely disseminated in schools and may ultimately lead to reduced rates of suicide and suicidal behaviour in school students across the region.

Twenty-six years of psychosocial interventions to reduce suicide risk in adolescents: Systematic review and meta-analysis

BACKGROUND

During adolescence, suicide risk increases; effective treatments are needed to reduce risk.

METHODS

Databases were searched (1995-2020) for randomized controlled trials (RCTs) concerning psychosocial treatments for suicide prevention in adolescents (10-18 yrs). Data were extracted from the timepoint closest to 6 months. Cohen's ds were estimated for reducing suicidal ideation (SI), self-harming behaviors (SHB) excluding strictly non-suicidal self-injury, and suicide attempts (SA) and analyzed using generalized least square regression. Meta-analytic innovations included within-person correlations to reflect trait suicidality; annualization to control for exposure; estimated lifetime risk based on ages; and modeling inclusion/exclusion criteria. Alternate approaches included relative risk and comparison of intervention and control treatments to baseline.

RESULTS

Of 30 RCTs, 6 assessing SHB (4 measuring SA), and 7 assessing SI demonstrated treatment effectiveness. Overall, interventions decreased SI (n = 25) with low effect size (d = 0.08, p = 0.01), non-significant after controlling for publication bias (d = 0.05, p = 0.1); interventions were non-significant for SHB (n = 25, d = 0.001, p = 0.97) or SA (n = 18, d = 0.03, p = 0.52). To prevent one SHB, the number needed to treat (NNT) was 45[26,156]; for SA, NNT=42[24,149]. Non-superiority may relate to effectiveness of control treatments. Thus, experimental and control treatments also were compared to baseline: both reduced SI (p < 0.0001), and effectiveness improved for SHB (NNT=12) and SA (NNT=11).

LIMITATIONS

Study heterogeneity and inconsistent statistical reporting limited meta-analysis.

CONCLUSIONS

Psychosocial interventions for suicide risk in adolescents showed little effectiveness compared with control treatments; suicide outcomes improved in both groups compared to baseline. Different approaches may be needed, including precision medicine methodologies and standardized statistical reporting criteria.

Hippocampal neuropathology in suicide: Gaps in our knowledge and opportunities for a breakthrough

Suicide is a major global hazard. There is a need for increasing suicide awareness and effective and evidence-based interventions, targeting both suicidal ideation and conduct. However, anti-suicide pharmacological effects are unsatisfactory. The human hippocampus is vulnerable to neuropsychiatric damages and subsequently releases psychobiological signals. Human hippocampal studies of suicide completers have shown mechanistic changes in neurobiology, which, however, could not reflect the neuropathological 'fingerprints' of fatal suicide ideations and suicide attempts. In this review, we provide several leading theories of suicide, including the serotoninergic system, Wnt pathway and brain-derived neurotrophic factor/tropomyosin receptor kinase B signalling, and discuss the evidence for their roles in suicide and treatment. Moreover, the cognitive dysfunctions associated with suicide risk are discussed, as well as the novel evidence on cognitive therapies that decrease suicidal ideation. We highlight the need to apply multi-omics techniques (including single-nucleus RNA sequencing and mass spectrometry histochemistry) on hippocampal samples from donors who died by suicide or legal euthanasia, to clarify the aetiology of suicide and propose novel therapeutic strategies.

Validation of a brief tool to assess and monitor suicidal ideation: The Youth Suicide Ideation Screen (YSIS-3)

BACKGROUND

. Suicidal ideation is common in young people. Assessment and monitoring can help to understand its dynamic nature and inform treatment planning.

AIMS

. The aims were to evaluate psychometric properties of a brief screening tool - the Youth Suicide Ideation Screen-3 item (YSIS-3) and determine its correlation with the Suicidal Ideation Question-Junior (SIQ-JR) and measures of depressive and anxiety symptoms a.

METHOD

. Cronbach's alpha (α) was used to evaluate internal consistency of the YSIS-3 in 1107 young people. Convergent validity was evaluated using network analysis based on individual item polychoric correlations. Structural equation modelling was used to understand latent constructs; pearson product moment correlations to validate the integrity of the underlying construct. and two-way mixed Intraclass Correlation Coefficient to examine longitudinal stability and Cohen's d to assess sensitivity to change.

RESULTS

. The YSIS-3 was found to have internal consistency, convergent validity and criteria validity almost identical to the 15-item SIQ-JR. There was a high correlation (0.91) between the latent factor underpinning YSIS-3 and SIQ-JR. The YSIS-3 was more sensitive to change among those presenting with suicidal ideation at baseline.

CONCLUSIONS

. The YSIS-3 is a valid measure for the assessment and monitoring of suicidal ideation, and is sensitive to change. This brief measure can contribute to regular monitoring of the presence and nature of suicidal ideation, which when included in comprehensive assessment, will inform the clinical management of those at risk of suicide.

Improving Suicide Prevention Through Evidence-Based Strategies: A Systematic Review

OBJECTIVE

The authors sought to identify scalable evidence-based suicide prevention strategies.

METHODS

A search of PubMed and Google Scholar identified 20,234 articles published between September 2005 and December 2019, of which 97 were randomized controlled trials with suicidal behavior or ideation as primary outcomes or epidemiological studies of limiting access to lethal means, using educational approaches, and the impact of antidepressant treatment.

RESULTS

Training primary care physicians in depression recognition and treatment prevents suicide. Educating youths on depression and suicidal behavior, as well as active outreach to psychiatric patients after discharge or a suicidal crisis, prevents suicidal behavior. Meta-analyses find that antidepressants prevent suicide attempts, but individual randomized controlled trials appear to be underpowered. Ketamine reduces suicidal ideation in hours but is untested for suicidal behavior prevention. Cognitive-behavioral therapy and dialectical behavior therapy prevent suicidal behavior. Active screening for suicidal ideation or behavior is not proven to be better than just screening for depression. Education of gatekeepers about youth suicidal behavior lacks effectiveness. No randomized trials have been reported for gatekeeper training for prevention of adult suicidal behavior. Algorithm-driven electronic health record screening, Internet-based screening, and smartphone passive monitoring to identify high-risk patients are understudied. Means restriction, including of firearms, prevents suicide but is sporadically employed in the United States, even though firearms are used in half of all U.S. suicides.

CONCLUSIONS

Training general practitioners warrants wider implementation and testing in other nonpsychiatrist physician settings. Active follow-up of patients after discharge or a suicide-related crisis should be routine, and restricting firearm access by at-risk individuals warrants wider use. Combination approaches in health care systems show promise in reducing suicide in several countries, but evaluating the benefit attributable to each component is essential. Further suicide rate reduction requires evaluating newer approaches, such as electronic health record-derived algorithms, Internet-based screening methods, ketamine's potential benefit for preventing attempts, and passive monitoring of acute suicide risk change.

Systematic review and narrative synthesis of suicide prevention in high-schools and universities: a research agenda for evidence-based practice

Background

Youth suicide prevention in high-schools and universities is a public health priority. Our aim was to propose a research agenda to advance evidence-based suicide prevention in high-schools and universities by synthesizing and critically reviewing the research focus and methodologies used in existing intervention studies.

Methods

Fourteen databases were systematically searched to identify studies which evaluate suicide prevention interventions delivered on high-school or university campuses, with before and after measures. Data from included studies (n = 43) were extracted to identify what, where, how and for whom interventions have been tested. Narrative synthesis was used to critically evaluate research focus and methodology. Study quality was assessed.

Results

Research has focused primarily on selective interventions, with less attention on indicated and universal interventions. Most evidence comes from North America and high-income countries. The target of interventions has been: non-fatal suicidal behaviour; confidence and ability of staff/students to intervene in a suicidal crisis; suicide-related knowledge and attitudes; and suicide-related stigma. No studies included suicide deaths as an outcome, evaluated eco-systemic interventions, explored how context influences implementation, used multisite study designs, or focused explicitly on LGBTQ+ youth. Two studies evaluated digital interventions. Quality of the majority of studies was compromised by lack of methodological rigour, small samples, and moderate/high risk of bias. Interventions often assume the existence of an external well-functioning referral pathway, which may not be true in low-resource settings.

Conclusion

To advance evidence-based suicide prevention in educational settings we need to: conduct more high-quality clinical and pragmatic trials; promote research in low- and middle-income countries; test targeted interventions for vulnerable populations (like LGBTQ+ youth), evaluate interventions where death by suicide is the primary outcome; include translational studies and use implementation science to promote intervention uptake; evaluate the potential use of digital and eco-systemic interventions; and conduct multisite studies in diverse cultural settings.

Innovating Technology-Enhanced Interventions for Youth Suicide: Insights for Measuring Implementation Outcomes

Technology is one medium to increase youth engagement, especially among underserved and minority groups, in suicide preventive interventions. Technology can be used to supplement or adjunct an in-person intervention, guide an in-person intervention, or be the stand-alone (automated) component of the intervention. This range in technological use is now called the continuum of behavioral intervention technologies (BITs). Overall, suicide intervention researchers do not use this terminology to categorize how the role of technology differs across technology-enhanced youth interventions. There is growing recognition that technology-enhanced interventions will not create substantial public health impact without an understanding of the individual (youth, families, and providers), mezzo (clinics and health systems of care), and contextual factors (society, culture, community) that are associated with their implementation. Implementation science is the study of methods to promote uptake of evidence-based practices and policies into the broader health care system. In this review, we incorporate work from implementation science and BIT implementation to illustrate how the study of technology-enhanced interventions for youth suicide can be advanced by specifying the role of technology and measuring implementation outcomes.

Effectiveness of internet-based cognitive behavioral therapy for suicide: a systematic review and meta-analysis of RCTs

Suicidal individuals rarely seek help and receive professional psychological intervention on their initiative. Internet-based cognitive behavioral therapy(iCBT) can increase availability and reduce stigma compared to face-to-face interventions for suicide.However, conclusions about the effectiveness of iCBT on suicide are controversial. The review aimed to determine the effectiveness of iCBT on reducing suicidal ideation (primary outcomes) and other outcomes related to suicide like suicide attempts(secondary outcomes). PubMed, the Cochrane Library, EMBASEwere searched up to March 2020 for RCTs of iCBT which aimed to reduce suicide.The potential bias was assessed by the Cochrane risk of bias tool. Data analyses wereperformed by RevMan5.3.Four studies meeting the eligibility criteria were included which reported data on a total of 1225 participants. We found iCBT was associated with reducing an individual's suicidal ideation, and first indications suggest that the treatment effect might be even more pronounced in the short term and in adults.Additionally, there was insufficient evidence to prove its effectiveness in reducing suicide attempts and suicide death.Overall, iCBT can overcome the disadvantages of traditional interventions and show promise on suicidal ideation. While ensuring safety and ethics, further studies are warranted, focusing on suicide specific behavior like suicide attempts.

Information and Communication Technology Use in Suicide Prevention: Scoping Review

BACKGROUND

The use of information and communication technology (ICT) in suicide prevention has progressed rapidly over the past decade. ICT plays a major role in suicide prevention, but research on best and promising practices has been slow.

OBJECTIVE

This paper aims to explore the existing literature on ICT use in suicide prevention to answer the following question: what are the best and most promising ICT practices for suicide prevention?

METHODS

A scoping search was conducted using the following databases: PubMed, PsycINFO, Sociological Abstracts, and IEEE Xplore. These databases were searched for articles published between January 1, 2013, and December 31, 2018. The five stages of the scoping review process were as follows: identifying research questions; targeting relevant studies; selecting studies; charting data; and collating, summarizing, and reporting the results. The World Health Organization suicide prevention model was used according to the continuum of universal, selective, and indicated prevention.

RESULTS

Of the 3848 studies identified, 115 (2.99%) were selected. Of these, 10 regarded the use of ICT in universal suicide prevention, 53 referred to the use of ICT in selective suicide prevention, and 52 dealt with the use of ICT in indicated suicide prevention.

CONCLUSIONS

The use of ICT plays a major role in suicide prevention, and many promising programs were identified through this scoping review. However, large-scale evaluation studies are needed to further examine the effectiveness of these programs and strategies. In addition, safety and ethics protocols for ICT-based interventions are recommended.

Trajectories of change in depression symptoms and suicidal ideation over the course of evidence-based treatment for depression: Secondary analysis of a randomised controlled trial of cognitive behavioural therapy plus fluoxetine in young people

OBJECTIVES

Effective treatment of depression is a key target for suicide prevention strategies. However, only around one-third of young people with suicide risk respond to evidence-based treatments. Understanding the trajectory of suicidal ideation, as a marker of suicide risk, over the course of evidence-based treatment for depression might provide insight into more targeted and effective treatments.

METHODS

This is a secondary analysis of data from the multicentre Youth Depression Alleviation-Combined Treatment trial. A total of 153 young people aged 15-25 years diagnosed with major depressive disorder were randomly assigned in this double-blind, placebo-controlled trial to either cognitive behavioural therapy plus fluoxetine or cognitive behavioural therapy plus placebo. Participants were assessed for depression and suicidal ideation at baseline and at weeks 4, 8 and 12.

RESULTS

Using group-based trajectory modelling, we identified two distinct depression trajectories. The first (Improving; 54.9%; n = 83) comprised those who experienced a consistent decline in depression symptoms. The second (Persisting; 45.1%; n = 70) comprised those who, despite treatment, still had clinically significant levels of depression by the end of treatment. For suicidal ideation, we identified four distinct trajectories: Non-clinical (15.5%; n = 20), Low Improving (47.1%; n = 75), High Improving (24.8%; n = 38) and High Persisting (12.7%; n = 20). Treatment allocation was not significantly associated with trajectory membership for either depression or suicidal ideation.

CONCLUSION

Understanding the course of depression and suicidal ideation during treatment has important implications for managing suicide risk. The findings suggest that there is an identifiable group of young people for whom enhanced psychological and/or pharmacological intervention might be required to ensure a better treatment response. Specific interventions for those with suicidal ideation may also be prudent from the outset.

The Youth Depression Alleviation-Combined Treatment trial was prospectively registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12612001281886).

Universal and Selective Interventions to Prevent Poor Mental Health Outcomes in Young People: Systematic Review and Meta-analysis

BACKGROUND

Much is not known about the efficacy of interventions to prevent poor mental health outcomes in young people by targeting either the general population (universal prevention) or asymptomatic individuals with high risk of developing a mental disorder (selective prevention).

METHODS

We conducted a PRISMA/MOOSE-compliant systematic review and meta-analysis of Web of Science to identify studies comparing post-test efficacy (effect size [ES]; Hedges' g) of universal or selective interventions for poor mental health outcomes versus control groups, in samples with mean age <35 years (PROSPERO: CRD42018102143). Measurements included random-effects models, I2 statistics, publication bias, meta-regression, sensitivity analyses, quality assessments, number needed to treat, and population impact number.

RESULTS

295 articles (447,206 individuals; mean age = 15.4) appraising 17 poor mental health outcomes were included. Compared to control conditions, universal and selective interventions improved (in descending magnitude order) interpersonal violence, general psychological distress, alcohol use, anxiety features, affective symptoms, other emotional and behavioral problems, consequences of alcohol use, posttraumatic stress disorder features, conduct problems, tobacco use, externalizing behaviors, attention-deficit/hyperactivity disorder features, and cannabis use, but not eating-related problems, impaired functioning, internalizing behavior, or sleep-related problems. Psychoeducation had the highest effect size for ADHD features, affective symptoms, and interpersonal violence. Psychotherapy had the highest effect size for anxiety features.

CONCLUSION

Universal and selective preventive interventions for young individuals are feasible and can improve poor mental health outcomes.

Comparative Efficacy and Acceptability of Psychotherapies for Self-harm and Suicidal Behavior Among Children and Adolescents: A Systematic Review and Network Meta-analysis

IMPORTANCE

Self-harm and suicidal behavior are associated with substantial morbidity and mortality among children and adolescents. The comparative performance of psychotherapies for suicidality is unclear because few head-to-head clinical trials have been conducted.

OBJECTIVE

To compare the efficacy of psychotherapies for the treatment of self-harm and suicidality among children and adolescents.

DATA SOURCES

Four major bibliographic databases (PubMed, MEDLINE, PsycINFO, and Embase) were searched for clinical trials comparing psychotherapy with control conditions from inception to September 2020.

STUDY SELECTION

Randomized clinical trials comparing psychotherapies for suicidality and/or self-harm with control conditions among children and adolescents were included after a blinded review by 3 independent reviewers (A.B., M.P., and J.W.).

DATA EXTRACTION AND SYNTHESIS

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed for data abstraction, and the Cochrane risk of bias tool was used to evaluate study-level risk of bias. Data abstraction was performed by 1 reviewer (A.B.) and confirmed by 2 independent blinded reviewers (J.W. and M.P.). Data were analyzed from October 15, 2020, to February 15, 2021.

MAIN OUTCOMES AND MEASURES

The primary outcomes were dichotomized self-harm and retention in treatment. The secondary outcomes were dichotomized all-cause treatment discontinuation and scores on instruments measuring suicidal ideation and depressive symptoms. Effect sizes were pooled using frequentist random-effects network meta-analysis models to generate summary odds ratios (ORs) and Cohen d standardized mean differences (SMDs). Negative Cohen d SMDs or ORs less than 1 indicated that the treatment reduced the parameter of interest relative to the control condition (eg, signifying a beneficial association with suicidal ideation).

RESULTS

The systematic search generated 1272 unique records. Of those, 44 randomized clinical trials (5406 total participants; 4109 female participants [76.0%]) from 49 articles were selected (5 follow-up studies were merged with their primary clinical trials to avoid publication bias). The selected clinical trials spanned January 1, 1995, to December 31, 2020. The median duration of treatment was 3 months (range, 0.25-12.00 months), and the median follow-up period was 12 months (range, 1-36 months). None of the investigated psychotherapies were associated with increases in study withdrawals or improvements in retention in treatment compared with treatment as usual. Dialectical behavioral therapies were associated with reductions in self-harm (OR, 0.28; 95% CI, 0.12-0.64) and suicidal ideation (Cohen d SMD, -0.71; 95% CI, -1.19 to -0.23) at the end of treatment, while mentalization-based therapies were associated with decreases in self-harm (OR, 0.38; 95% CI, 0.15-0.97) and suicidal ideation (Cohen d SMD, -1.22; 95% CI, -2.18 to -0.26) at the end of follow-up. The quality of evidence was downgraded because of high risk of bias overall, heterogeneity, publication bias, inconsistency, and imprecision.

CONCLUSIONS AND RELEVANCE

Although some psychotherapeutic modalities appear to be acceptable and efficacious for reducing self-harm and suicidality among children and adolescents, methodological issues and high risk of bias prevent a consistent estimate of their comparative performance.

Saving Lives: Recognizing and Intervening with Youth at Risk for Suicide

Suicide is the second leading cause of death for youth in the United States. Fortunately, substantial advances have been achieved in identifying and intervening with youth at risk. In this review, we first focus on advances in proactive suicide risk screening and psychoeducation aimed at improving the recognition of suicide risk. These strategies have the potential to improve our ability to recognize and triage youth at risk who may otherwise be missed. We then review recent research on interventions for youth at risk. We consider a broad range of psychotherapeutic interventions, including crisis interventions in emergency care settings. Though empirical support remains limited for interventions targeting suicide risk in youth, effective and promising approaches continue to be identified. We highlight evidence-based screening and intervention approaches as well as challenges in these areas and recommendations for further investigation.

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.

Characteristics of effective online interventions: implications for adolescents with personality disorder during a global pandemic

In recent years, the necessity of providing online interventions for adolescents, as an alternative to face-to-face interventions, has become apparent due to several barriers some adolescents face in accessing treatment. This need has become more critical with the coronavirus disease 2019 (COVID-19) global pandemic impacting the delivery of psychotherapy and limiting accessibility of face-to-face therapy. Whilst it has been established that face-to-face psychotherapy for adolescents with personality disorder can be effective in reducing the impact these complex mental illnesses have on functioning, online interventions for adolescents are rare, and to our knowledge there are no empirically validated online interventions for personality disorder. The development of novel online interventions are therefore necessary. To inform the development of online interventions for adolescents with personality disorder or symptoms of emerging personality disorder, a two-phase rapid review was conducted. Phase one consisted of a search and examination of existing online mental health programs for adolescents with symptoms of personality disorder, to understand how to best use online platforms. Phase two consisted of a rapid review of empirical literature examining online interventions for adolescents experiencing symptoms of personality disorder to identify characteristics that promote efficacy. There were no online programs specific to personality disorder in adolescence. However, 32 online mental health programs and 41 published empirical studies were included for analysis. Common intervention characteristics included timeframes of one to two months, regular confidential therapist contact, simple interactive online components and modules, and the inclusion of homework or workbook activities to practice new skills. There is an urgent need for online interventions targeting personality dysfunction in adolescence. Several characteristics of effective online interventions for adolescents were identified. These characteristics can help inform the development and implementation of novel online treatments to prevent and reduce the burden and impact of personality disorder, or symptoms of emerging personality disorder, in adolescents. This has implications for the COVID-19 pandemic when access to effective online interventions has become more urgent.

Preventive digital mental health interventions for children and young people: a review of the design and reporting of research

Digital health interventions (DHIs) have frequently been highlighted as one way to respond to increasing levels of mental health problems in children and young people. Whilst many are developed to address existing mental health problems, there is also potential for DHIs to address prevention and early intervention. However, there are currently limitations in the design and reporting of the development, evaluation and implementation of preventive DHIs that can limit their adoption into real-world practice. This scoping review aimed to examine existing evidence-based DHI interventions and review how well the research literature described factors that researchers need to include in their study designs and reports to support real-world implementation. A search was conducted for relevant publications published from 2013 onwards. Twenty-one different interventions were identified from 30 publications, which took a universal (n = 12), selective (n = 3) and indicative (n = 15) approach to preventing poor mental health. Most interventions targeted adolescents, with only two studies including children aged ≤10 years. There was limited reporting of user co-design involvement in intervention development. Barriers and facilitators to implementation varied across the delivery settings, and only a minority reported financial costs involved in delivering the intervention. This review found that while there are continued attempts to design and evaluate DHIs for children and young people, there are several points of concern. More research is needed with younger children and those from poorer and underserved backgrounds. Co-design processes with children and young people should be recognised and reported as a necessary component within DHI research as they are an important factor in the design and development of interventions, and underpin successful adoption and implementation. Reporting the type and level of human support provided as part of the intervention is also important in enabling the sustained use and implementation of DHIs.

The Role of Technology and the Continuum of Care for Youth Suicidality: Systematic Review

Background

Youth suicide is a global public health issue, and using technology is one strategy to increase participation in preventive interventions. However, there is minimal knowledge on how technology-enhanced interventions for youth correspond to the stages of care, from illness or risk recognition to treatment follow-up.

Objective

This systematic review aims to examine the efficacy of technology-enhanced youth suicide prevention and interventions across the continuum of care.

Methods

Four electronic databases were searched up to spring 2019 for youth suicide preventive interventions that used technology. The review was not restricted by study design and eligible studies could report outcomes on suicidality or related behaviors, such as formal treatment initiation. An adapted version of the Methodological Quality Ratings Scale was used to assess study quality.

Results

A total of 26 studies were identified. The findings support the emerging efficacy of technology-enhanced interventions, including a decline in suicidality and an increase in proactive behaviors. However, evidence suggests that there are gaps in the continuum of care and recent study samples do not represent the diverse identities of vulnerable youth.

Conclusions

The majority of identified studies were conducted in school settings and were universal interventions that aligned with the illness and risk recognition and help-seeking stages of the continuum of care. This field could be strengthened by having future studies target the stages of assessment and treatment initiation, include diverse youth demographics, and examine the varying roles of providers and technological components in emerging interventions.

Adaptation of evidence-based suicide prevention strategies during and after the COVID-19 pandemic

Suicide is preventable. Nevertheless, each year 800,000 people die of suicide in the world. While there is evidence indicating that suicide rates de-crease during times of crises, they are expected to increase once the immediate crisis has passed. The COVID-19 pandemic affects risk and pro-tective factors for suicide at each level of the socio-ecological model. Economic downturn, augmented barriers to accessing health care, increased access to suicidal means, inappropriate media reporting at the societal level; deprioritization of mental health and preventive activities at the community level; interpersonal conflicts, neglect and violence at the relationship level; unemployment, poverty, loneliness and hopelessness at the individual level: all these variables contribute to an increase of depression, anxiety, post-traumatic stress disorder, harmful use of alcohol, substance abuse, and ultimately suicide risk. Suicide should be prevented by strengthening universal strategies directed to the entire population, including mitigation of unemployment, poverty and inequalities; prioritization of access to mental health care; responsible media reporting, with information about available support; prevention of increased alcohol intake; and restriction of access to lethal means of suicide. Selective interventions should continue to target known vulnerable groups who are socio-economically disadvantaged, but also new ones such as first responders and health care staff, and the bereaved by COVID-19 who have been deprived of the final contact with loved ones and funerals. Indicated preventive strategies targeting individuals who display suicidal behaviour should focus on available pharmacological and psychological treatments of mental disorders, ensuring proper follow-up and chain of care by increased use of telemedicine and other digital means. The scientific community, health care professionals, politicians and decision-makers will find in this paper a systematic description of the effects of the pandemic on suicide risk at the society, community, family and individual levels, and an overview of how evidence-based suicide preventive interventions should be adapted. Research is needed to investigate which adaptations are effective and in which con-texts.

Are Korean children free from suicide? Risk and protective factors within a transactional-ecological perspective

This study aimed to explore and identify the trends and risks, as well as the protective factors of child suicide in Korea. Data from the 10th year Korea Welfare Panel Study in 2016 were used. These data were collected from 458 fourth to sixth grade boys and girls in elementary schools. The results showed that the mean suicidal ideation score was 1.55, the suicide attempt rate was .9%, and the mean number of suicide attempts was .2. Suicidal ideation was more prevalent in children who reported the absence of a parental figure, frequent experiences of school violence, increased Internet use, and decreased guidance and supervision from parents. The presence of parental figure explained the greatest amount of variance. Logistic regression analysis with suicide attempts as the dependent variable demonstrated that family income was a significant variable. Regarding the mediating roles of depression and anxiety, Internet usage directly affected children's suicidal ideation, while the experience of school violence, academic stress, and parents' guidance and supervision affected suicidal ideation, which was mediated by the child's depression and anxiety. Depression and anxiety had a positive impact on suicidal ideation. Based on these results, implications and interventions were suggested.

Risk of repetition and subsequent self-harm following presentation to hospital with suicidal ideation: A longitudinal registry study

BACKGROUND

Few studies have focused on those who present to hospital with suicidal thoughts (suicidal ideation). The aim of this study was to establish the risk of repeat presentation to hospital following suicidal ideation and to identify factors which were associated with further ideation or subsequent self-harm.

METHODS

Data were obtained from the Northern Ireland Registry of Self-harm. Risk of repeat presentation following hospital-presenting ideation was analysed using Kaplan Meier analyses, specifically cox proportional hazard models.

FINDINGS

During the period April 2014 to March 2019, a total of 14,695 presentations to hospital due to suicidal ideation were made in Northern Ireland. The cumulative incidence of repeat presentation to hospital was 40·5% within five years, with an 18·3% risk of subsequent self-harm. Previous ideation had the strongest association with repeat presentation. There was evidence of recidivism considering further ideation, with an increased risk according to number of previous presentations. In contrast, risk of subsequent self-harm was highest after the first or second presentation. Male gender and alcohol were associated with further ideation, while females and young people were more likely to re-present with self-harm.

INTERPRETATION

The findings indicate that individuals who present to hospital with suicidal ideation are at risk of repeat presentation and future self-harm, however clinical guidelines do not specifically address hospital-presenting ideation. The transition from ideation to suicidal behaviour is important to consider and research could inform effective screening and early intervention measures.

ROLE OF FUNDING

The Northern Ireland Registry of Self-harm is funded by the Public Health Agency, Northern Ireland.

Effects of perceived stress and resilience on suicidal behaviors in early adolescents

Suicidal behaviors are significant public health issues. The aim of the current study is to examine the effects of perceived stress and resilience on suicidal ideation (SI), plan (SP), and attempt (SA) among early adolescents. A longitudinal study was conducted with data collected from 1035 junior high-school students at baseline and 1-year follow-up. Participants were assessed for suicidal behaviors, resilience, and perceived stress. Logistic regression was performed to analyze for the associations between independent variables and suicidal behaviors. 210 (20.3%) of the participants reported to have SI, 59 (5.7%) had SP, and 49 (4.7%) had SA at baseline. Perceived stress was a strong risk factor (p < 0.001) for SI (OR 1.16-1.18), SP (OR 1.20-1.21), and SA (OR 1.12-1.16) while accounting for different dimensions of resilience. Students with persistent high stress during the 1-year follow-up period had significantly increased risk of SI (OR 7.14-9.64), SP (OR 3.92-6.37), and SA (OR 3.76-3.84) than the persistent low-stress group (p < 0.01). Increased perceived stress scale (PSS) (OR 2.89-3.15) and decreased PSS (OR 2.47) also had a higher risk for SI than persistent low PSS group. Moreover, students with high perceived stress who reported to have higher hope and optimism were less likely to show SI (OR 0.90, p = 0.001) and SP (OR 0.87, p = 0.002) at baseline, and the problem-solving and cognitive maturity mature dimension of resilience showed a significant protective effect on SP longitudinally (OR 0.25, p = 0.003). Perceived stress substantially increased the risk for suicidal behaviors, and moderates the protective effect of resilience on suicide. Considering both risk and protective factors of suicidal behaviors is essential in designing future suicide prevention and intervention programs.
