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

Adolescent, caregivers, and therapists' experiences of youth and family suicide intervention: A qualitative study

OBJECTIVE

This study explores the experience of an individual and family therapy youth suicide intervention from the perspectives of seven psychotherapy triads (young people aged 12-18, their parents/caregivers and therapists).

METHOD

Data were collected through semi-structured individual interviews and analyzed using consensual qualitative research methods.

RESULTS

Four domains were identified: Focusing on the youth-parent relationship, individual therapy for young people and their parents, conjoint therapy, and public service structures and systemic practice that facilitated tailored treatment. All participant groups valued intervention that improved the youth-parent relationship; however, they held different views about its influence on suicidality and recovery. Separate youth and parent therapy was crucial for facilitating the tailoring of treatment and enhancing the reparative potential of conjoint therapy. Barriers to productive intervention included inaccessible, fragmented, and siloed treatment that excluded parents, stigmatizing clinician responses, and acute care that was not attuned to need or developmental context. Helpful intervention was systemically and attachment-informed, multi-disciplinary, individually tailored, and integrated freely available specialist therapy with crisis and inpatient care.

CONCLUSION

A relational, nuanced, and flexible approach is needed to tailor youth suicide treatment in the context of the complexity of youth-parent relationships.

Factors Associated with Suicidal Behavior in Adolescents: An Umbrella Review Using the Socio-Ecological Model

Adolescent suicide is a critical social issue with profound and lasting individual and collective consequences. This umbrella review examines factors associated with adolescent suicidal behavior through the socioecological framework of prevention and seeks to identify gaps in the existing literature. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included a comprehensive search of the of the Web of Science, Scopus, and Cochrane databases in both English and Spanish, covering the period from 2018 to 2024, using terms related to adolescence and suicidal behavior. Out of 6,138 articles identified, 37 met the quality criteria and were selected for analysis. The studies highlighted individual risk factors such as age, gender, belonging to ethnic or gender minorities, emotional disorders, self-destructive behavior, emotional regulation, and experience of physical or emotional pain. Interpersonal factors such as parental relationships, sexual abuse, social isolation, peer pressure, and loneliness were also found. However, the review revealed a worrying lack of studies on societal and community factors and a paucity of research focusing on protective factors. The study highlights the need to include factors related to the physical and social environments that influence health and behavior in future research, as well as to enhance the resources and strengths of adolescents.

Suicide, neuroinflammation and other physiological alterations

Suicide is considered one of the major public health problems worldwide, being the second leading cause of death in the 15-29 age group. It is estimated that every 40s someone in the world commits suicide. The social taboo surrounding this phenomenon as well as the fact that suicide prevention measures currently fail to avoid deaths from this cause, means that more research is needed to understand its mechanisms. The present narrative review on suicide tries to point out several important aspects, such as risk factors or the dynamics of suicide, as well as the current findings in the field of physiology that could offer advances in the understanding of suicide. Subjective measures of risk such as scales and questionnaires are not effective alone, whereas the objective measures can be addressed from physiology. Thus, an increased neuroinflammation in people who take their own lives has been found, with an increase in inflammatory markers such as interleukin-6 and other cytokines in plasma or cerebrospinal fluid. Also, the hyperactivity of the hypothalamic-pituitary-adrenal axis and a decrease in serotonin or in vitamin D levels seems to also be involved. In conclusion, this review could help to understand which factors can trigger an increased risk of dying by suicide, as well as pointing out those alterations that occur in the body when someone attempt to commit suicide or succeeds in taking their own life. There is a need for more multidisciplinary approaches that address suicide to help to raise awareness of the relevance of this problem that causes the death of thousands of people every year.

The Effectiveness of Preventative Interventions to Reduce Mental Health Problems in at-risk Children and Young People: A Systematic Review of Reviews

Mental health problems are the leading cause of childhood disability worldwide, resulting in poor outcomes for children and young people that persist into adulthood. It is essential that those young people most at risk of developing mental health problems receive effective preventative interventions. Whilst there have been a number of systematic reviews which have examined the effectiveness of secondary prevention interventions for specific groups of children and young people, or to address identified mental health concerns, no review has engaged with the breadth of this literature. We conducted a systematic review of systematic reviews to map this complex field of secondary preventative interventions and identify effective interventions to prevent mental health problems in children and adolescents aged 3-17 years. The review protocol was registered on PROSPERO. We searched five electronic databases from inception to February 2023. The certainty of the evidence was appraised using the AMSTAR 2. We included 49 unique systematic reviews each including between 2 and 249 (mean 34) unique studies; the majority of which were reviews which included only or mostly randomised controlled trials (70%). The reviews examined selective interventions (defined as interventions which are delivered to sub-group populations of young people at increased risk of mental health problems) (n = 22), indicated interventions (defined as interventions which target young people who are found to have pre-clinical symptoms) (n = 15) or a synthesis of both (n = 12). The certainty of the evidence in the reviews was rated as high, (n = 12) moderate (n = 5), low (n = 9) and critically low (n = 23). We found evidence to support both selective and indicated interventions in a range of populations and settings, with most of this evidence available for children and young people in their mid-years (6-10 years) and early adolescence (11-13 years). There was a large body of evidence suggesting that resilience enhancing, cognitive behaviour therapy-based and psychoeducational interventions for children who experience adversity, or those with subclinical externalising problems may offer promise. Early selective interventions for a subpopulation of children and young people who have experienced adversity which combines risk reduction and resilience enhancing approaches directed at children and their families may be effective at reducing mental health problems.

Bridging Gaps in Care Following Hospitalization for Suicidal Adolescents: As Safe As Possible (ASAP) and BRITE App

OBJECTIVE

We present results from a 2-site, randomized clinical trial to assess the efficacy of a brief intervention (As Safe As Possible [ASAP]), a safety plan phone application (BRITE), and their combination on suicide attempts, suicidal ideation, non-suicidal self-injury, re-hospitalizations. and suicidal events among adolescents.

METHOD

Adolescents (n= 240; 12-17 years of age) who were hospitalized for suicidal ideation with plan and/or intent, and/or suicide attempt, were assigned to 1 of 4 treatment conditions in a 2 by 2 design: ASAP+BRITE app+treatment as usual (TAU); (2) BRITE+TAU; (3) ASAP+TAU; and (4) TAU alone. Independent evaluators assessed suicidal ideation and behavior at 4, 12, and 24 weeks using the Columbia-Suicide Severity Rating Scale (C-SSRS) and re-hospitalization using the Child and Adolescent Services Assessment (CASA).

RESULTS

No group differences were found on primary outcomes, except that ASAP participants were less likely to be re-hospitalized over 6 months (15.6%, vs 26.5%, p = .046). Participants hospitalized for an attempt and assigned to BRITE had a lower rate of subsequent attempts (odds ratio [OR] = 0.16, p = .01) and a greater time to attempt (hazard ratio [HR] = 0.20, p = .02). ASAP+BRITE, albeit not statistically significant, was most consistently associated with a reduction (60% reduction) in suicide attempts.

CONCLUSION

ASAP, BRITE, and their combination are equally effective at decreasing risk for suicidal events 6 months post hospital discharge among suicidal adolescents; the ASAP intervention (with or without BRITE) was associated with lower rates of re-hospitalization. The BRITE app in youth hospitalized for suicide attempt had promising outcomes in regard to future attempts.

Building Resilience and Attachment in Vulnerable Adolescents: The Feasibility of a Virtually Delivered Group Intervention for Adolescents with Suicidal Ideation and Their Caregivers

Background

The COVID-19 pandemic required many interventions to be conducted virtually. Building Resilience and Attachment in Vulnerable Adolescents (BRAVA) is a group intervention designed for adolescents and their caregivers to reduce adolescent suicidal ideation (SI).

Objective

We aimed to adapt BRAVA for virtual delivery and evaluate its acceptability and feasibility.

Methods

We conducted an 8-week pre-post trial between October and December 2020. Six adolescents and six primary caregivers were recruited from a pediatric hospital in Ontario, Canada. Families completed a virtual intake and exit assessment together and 6 weekly BRAVA group sessions separately. Satisfaction feedback was collected after each group session and during their exit, and clinical outcomes were collected at intake and exit. Weekly team meetings were conducted to gather clinician feedback.

Results

The study uptake rate was 42.9% of eligible participants. There were no dropouts. Adolescent and caregiver attendance rates for group sessions were high (median = 6). Most youth (83.4%) and caregivers (66.7%) reported that the virtual process worked well. All caregivers (100%) agreed they would participate in a virtual group session again, compared with youth (50%). Providers approved of the virtual adaptation but identified potential improvements (e.g., manual content, safety procedures). Adolescent SI decreased significantly post-treatment (Mpre = 50.7, Mpost = 29.7, p = 0.002).

Conclusions

Virtual delivery of BRAVA is acceptable and feasible and may help reduce SI in adolescents. Uptake, retention, and satisfaction were high for adolescents and caregivers. Feedback collected will improve BRAVA for future evaluations, including a randomized controlled trial.

Genetic signatures of suicide attempt behavior: insights and applications

INTRODUCTION

Every year about 800,000 complete suicide events occur. The identification of biologic markers to identify subjects at risk would be helpful in targeting specific support treatments.

AREA COVERED

A narrative review defines the meta-analytic level of current evidence about the biologic markers of suicide behavior (SB). The meta-analytic evidence gathered so far indicates that the hypothesis-driven research largely failed to identify the biologic markers of suicide. The most consistent and replicated result was reported for: 1) 5-HTR2A T102C, associated with SB in patients with schizophrenia (OR = 1.73 (1.11-2.69)) and 2) BDNF Val66Met (rs6265), with the Met-Val + Val-Val carriers found to be at risk for suicide in the Caucasian population (OR: 1.96 (1.58-2.43)), while Val-Val vs. Val-Met + Met carriers found to be at risk for suicide in the Asian populations (OR: 1.36 (1.04-1.78)). GWAS-based meta-analyses indicate some positive replicated findings regarding the DRD2, Neuroligin gene, estrogen-related genes, and genes involved in gene expression.

EXPERT OPINION

Most consistent results were obtained when analyzing sub-samples of patients. Some promising results come from the implementation of the polygenic risk score. There is no current consensus about an implementable biomarker for SB.

Suicide in young people: screening, risk assessment, and intervention

Suicide is the fourth leading cause of death among young people worldwide and the third leading cause of death among those in the US. This review outlines the epidemiology of suicide and suicidal behavior in young people. It discusses intersectionality as an emerging framework to guide research on prevention of suicide in young people and highlights several clinical and community settings that are prime targets for implementation of effective treatment programs and interventions aimed at rapidly reducing the suicide rate in young people. It provides an overview of current approaches to screening and assessment of suicide risk in young people and the commonly used screening tools and assessment measures. It discusses universal, selective, and indicated evidence based suicide focused interventions and highlights components of psychosocial interventions with the strongest evidence for reducing risk. Finally, the review discusses suicide prevention strategies in community settings and considers future research directions and questions challenging the field.

Recent research advances in identification and prevention of youth suicide risk

PURPOSE OF THE REVIEW

The rate of youth suicidal behaviors has gradually increased over the last 15 years and continues to grow during the COVID-19 pandemic. This trend burdens mental health services and demands significant developments in risk detection and delivery of interventions to reduce the risk. In this article we outline significant advances and recent findings in youth suicide research that may facilitate strategies for identifying and preventing suicide risk among youth at risk in general and in specific risk groups.

RECENT FINDINGS

The rise in suicide and suicidal behaviors is most likely to affect young people of racial, ethnic, sexual, and gender identity minorities and those living in poverty or experiencing maltreatment. The suicide rate in children is rising and demands special attention. Proximal risk factors for suicidal behavior compared with suicidal ideation have been suggested to identify near-term suicidal risk. Effective and scalable prevention strategies were identified, and the role of new technologies in suicide prevention among youth is to be determined.

SUMMARY

To reach broader suicide prevention in youth and reduce the pressure on mental healthcare, public health approaches and improved service access for minority youth and those living in underserved areas of the world are needed.

The Effectiveness of Self-Esteem-Related Interventions in Reducing Suicidal Behaviors: A Systematic Review and Meta-Analysis

Suicide is a serious social issue and is often treated using psychological interventions. The current systematic review and meta-analysis aimed to investigate the effectiveness of self-esteem-related interventions on suicidal behaviors. A systematic literature search for randomized controlled trials (RCTs) including a self-esteem component was conducted on 29 May 2021 and updated on 4 April 2022. In total, 12 studies were included in the systematic review and five studies were included in the meta-analysis. Small effect sizes were found for suicidal ideation at post intervention [g = -0.24, 95% CI (-0.48, 0.00)] and a 3-month follow-up [g = -0.36, 95% CI (-0.62, -0.11)]. However, these results should be interpreted cautiously due to the limited number of included studies and varied sample population. In conclusion, the current review suggests that future intervention studies should incorporate self-esteem enhancement in the treatment of suicidal behaviors, especially for suicidal ideation.
