Objective: In 2020, Army National Guard members demonstrated greater risk of suicide than their military and civilian counterparts. Though literature on deployment-related experiences and suicidal ideation (SI) is mixed, investigations of specific deployment-related experiences (e.g., injuries) may further elucidate the relationship between deployment and suicide risk. Deployment-related injuries, including pain severity and functional impairment, have been linked to increased risk of SI, and correlates like perceived burdensomeness (PB) and hopelessness. The current study sought to examine the cross-sectional relationship between deployment-related injuries, including pain severity and functional impairment, and severity of SI through PB and hopelessness.

Method: Immediately post-deployment, Army National Guard members (N = 2,261) completed validated self-report measures on past-week SI, PB, hopelessness, and single items regarding injury sustained during deployment and associated functional impairment and pain severity.

Results: Indirect effect analyses revealed that experience of deployment-related injury was related to SI through PB and hopelessness (R² = .1993), functional impairment was related to SI through PB, and pain severity was related to SI through PB. Contrary to hypotheses, hopelessness was not associated with SI when PB was simultaneously considered.

Conclusions: Army National Guard members who develop a sense of PB related to their injury and functional impairment of that injury may be at increased risk for suicidal ideation. Military suicide-prevention efforts may be potentiated through targeting distorted cognitions such as PB and hopelessness, especially in service members who have been injured.

Objective: Having been bullied at school in childhood links to suicidality. We aimed at verifying earlier findings and delivering diverse data from a representative population-based sample of young adults to characterize the impacts beyond childhood.

Method: A random sample of adults, aged 18-28 years and representative of the general population living in Finland, participated in a nationwide health examination study. Adverse childhood experiences before the age of 16 years were analyzed for 779 participants in relation to lifetime suicidality (suicidal ideation, suicide attempts), current suicidal thoughts (HSCL-25), mental disorders (self-reports for lifetime, M-CIDI for DSM-IV during the past 12 months), current usage of mental health services, current usage of prescription medicines (ATC codes), current psychological distress (GHQ-12), and current work capacity and work ability.

Results: Having been bullied in childhood contributed to greater suicidality (p < 0.001), more frequent current usage of antipsychotics (p < 0.001) as well as antidepressants (p < 0.001), greater current psychological distress (p < 0.001), and poorer current work capacity (p < 0.001) as well as work ability (p < 0.001). Of the self-reported mental disorders on lifetime basis, psychosis had the strongest association (p = 0.03) with having been bullied, whereas the interview-based diagnosis of mental disorders during the past 12 months had no significant association.

Conclusions: Having been bullied at school before the age of 16 years was independently associated not only with suicidality, but also with the self-report of psychosis as well as a range of indicators of poorer mental health at the age of 18-28 years.

Objective: Suicide is a global health concern and developing brief and accessible interventions that can reduce suicide risk is crucial. Thwarted belongingness (TB; i.e., feeling like one doesn't belong) and perceived burdensomeness (PB; i.e., feeling like one is a burden on others) are associated with suicidality, and changes in these constructs predict changes in suicidal thoughts and behaviors. Self-compassion is a multifaceted construct that involves being open and kind to oneself and can be taught through brief writing tasks. Low self-compassion has been associated with TB, PB, and suicidal ideation, suggesting that enhancing self-compassion may decrease suicide risk. Thus, we conducted an open trial of a brief, online self-compassion intervention targeting TB and PB.

Method: Undergraduate students (N = 132) viewed an educational video on self-compassion and completed self-compassion writing tasks over the course of one week.

Results: Reactions to the intervention were positive, and participants reported significantly higher self-compassion scores following the intervention. However, TB and PB scores did not change from the baseline to the post-intervention assessment.

Conclusions: This open trial demonstrated the feasibility and acceptability of a fully online, brief self-compassion intervention, but its impact on reducing suicide risk should be assessed further using a randomized controlled design.

Objective: Many people at risk of suicide do not actively seek help. Suicide prevention efforts need to involve the general public to provide appropriate support to those in need. It is important to investigate the intention to help those at risk of suicide and the factors associated with helping intentions in the general population. We aimed to assess the intention to help people at risk and associated factors using a national representative sample.

Method: We conducted a national telephone survey of 1,087 Taiwanese adults and collected data regarding participants' socio-demographic characteristics, mental health status, helping intentions, misconceptions about suicide, and attitudes toward suicide and suicide prevention.

Results: The prevalence of high intentions to help people at risk of suicide was 56.5%. Helping intentions did not differ by sex, educational level, employment status, marital status, or mental health status. Those with high helping intentions were younger, less likely to have misconceptions about suicide or agree that suicide is a personal choice, and more likely to believe that suicide is preventable and support suicide prevention measures.

Conclusions: Suicide prevention education programs aimed to enhance helping intentions may usefully target debunking misconceptions about suicide and cultivating positive attitudes toward suicide prevention.

Background: In recent years, suicidal thoughts and behaviors have become increasingly common among children and adolescents, leading to an elevation in the number of visits to emergency departments in pediatric hospitals. In Israel, the rising demand for mental health treatment due to suicidal distress is also salient, creating prolonged wait periods and low case acceptance rates. Addressing the urgent need for streamlined interventions, the present study outlines the design and results of a non-inferiority effectiveness trial of an ultra-brief suicide crisis intervention based on Interpersonal Psychotherapy for Adolescents (IPT-A-SCI).

Methods: 309 children and adolescents presenting to the Depression and Suicide Clinic at Schneider Children's Medical Center of Israel with depressive and anxiety symptoms and/or suicidal ideation/behavior were assigned to either IPT-A-SCI, Treatment as Usual (TAU), or waitlist condition. Assessments were conducted pre- and post-intervention/after five sessions/five weeks (as secondary assessments) in accordance with group assignment.

Results: At secondary assessment, post IPT-A-SCI, suicide ideation, and behavior as well as depression and anxiety symptoms significantly decreased, with no group differences observed between IPT-A-SCI, TAU, and control groups.

Conclusion: IPT-A-SCI is feasible and as effective as the standard treatment in reducing suicidal, depressive, and anxiety symptoms among children and adolescents.

Objective: Suicidality in young adults is a serious and growing clinical and social problem. The theory of psychosocial ego development assumes that identity and intimacy are two key factors for adaptation and vulnerability in early adulthood. The aim of the present study was to test whether psychosocial identity and intimacy are related to suicidality in young adults, even when controlling for confounding variables (depressive symptoms, sex, age, health and economic assessment, religious commitment, and pandemic-related distress).

Method: Respondents aged 18-25 (n = 607) completed the Identity-Confusion and Intimacy-Isolation subscales from the Modified Erikson Psychosocial Stage Inventory, as well as the Patient Health Questionnaire-9, the Suicidal Behaviors Questionnaire-Revised and answered questions about the pandemic-related distress and various sociodemographic factors.

Results: At the level of bivariate analyses, both identity and intimacy were negatively associated with suicidal risk in the overall sample and with the frequency of suicidal ideation in the suicide risk subsample (n = 242). Weaker identity, but not intimacy, was associated with belonging to a suicide risk group in multivariable logistic regression. Moreover, ordinal regression showed that, in the subgroup with suicide risk, identity was negatively associated with the frequency of suicidal thoughts.

Conclusions: Identity is a negative correlate of suicidality in young adults. Identity-focused therapy may be a promising target for intervention in suicidal young adults.

Suicide a leading cause of death among adolescents and is nearly always preceded by suicidal ideation (SI). Concerningly, SI during adolescence is not uncommon, as it is reported by as much as 20% of American youth. As such, SI in adolescence has been the subject of substantial research. Literature points to anger in adolescence as a relatively strong correlate of SI. However, work is limited, focusing on cross-sectional associations between anger in adolescence and SI and conceptualizing anger as a broad construct, failing to investigate the many narrow facets that comprise it. We address these gaps by investigating anger in adolescence as a (1) cross-sectional and (2) prospective correlate of SI and (3) investigating broad versus narrow conceptualizations of anger in adolescence as they relate to SI. Among two samples (Study 1, nationally representative community-based youth, n = 1,729; Study 2, high-risk juvenile justice involved youth, n = 1,406), anger in adolescence was cross-sectionally related to SI. However, when controlling for SI at baseline, anger in adolescence was not a prospective risk factor for SI at follow-up, nine years later. Finally, narrow facets of anger (e.g., argumentative, defiant, irritable, resentful, spiteful) were not more closely related than broad conceptualizations of anger to SI. These findings indicate that while anger in adolescence is cross-sectionally associated with SI, it should not necessarily be viewed as a valid risk factor for development of SI over the course of nearly a decade. Further, findings did not elucidate any narrow facets of anger that are particularly linked with SI.

Objective: Although non-suicidal self-injury (i.e., NSSI) has been suggested as a robust risk factor of suicide, NSSI related information that is most related to suicide risk remains unclear. Commonly studied NSSI characteristics are its frequency and the number of methods endorsed. However, it may not be merely how frequent or how many different methods that matters, but "why," which alludes to the importance of NSSI functions (or why individuals engage in NSSI). Thus, this study examined how the interactions between NSSI characteristics and functions are associated with suicide risk.

Methods: Undergraduate students (n = 820) with a lifetime history of NSSI, filled out self-report measures on NSSI and suicide risk. A hierarchical regression analysis was conducted to examine the moderation effects between four 2-way interactions (i.e., method X intrapersonal; method X interpersonal; frequency X intrapersonal; frequency X interpersonal) on suicide risk.

Results: Main effects of all four independent variables were statistically significant. In terms of interactions, the intrapersonal function moderated both the effects of NSSI frequency and methods on suicide risk, whereas the interpersonal function moderated the effects of NSSI frequency on suicide risk.

Conclusion: Our results highlight that some NSSI related information than others are more indicative of suicide risk. In particular, the combination of NSSI functions, along with its frequency and number of methods, holds promise when assessing for current and lifetime suicidal thoughts and behaviors.

Introduction: Medical students have been known to face numerous mental health issues at disproportionately high rates. Of pertinence, medical students have been shown to have high rates of suicidal thoughts and behavior. However, little is known about the risks and warning signs for death by suicide in this group. We therefore conducted a systematic review regarding the factors associated with medical student suicide mortality.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted searches in six different databases. Studies with stratified data on at least one suicide death by a medical student were eligible for inclusion.

Results: Searches produced a total of 1744 articles, and of those, 13 articles were eligible for inclusion. There was a pooled total of 362 suicide deaths of medical students across five different countries. 67.6% of deaths occurred among male students, primarily in their early twenties. Students in their later years of medical school were shown to be more likely to die by suicide, as were those with a history of psychiatric issues such as depression. Motivations for suicide were academic stress/failure, harassment/bullying, and relationship issues. Warning signs for suicide among medical students were recent changes in mood/behavior and leaving a suicide note.

Discussion: Numerous risks and warning signs of suicide have been described in our review. Medical schools may have an important role in lowering suicide deaths by medical students; impactful change can occur through better support, changes in curriculum, and appropriate data collection.

Implicit identification with death (i.e., subconsciously self-associating oneself with death), measured by the Death-Suicide Implicit Association Test (D/S-IAT), is associated with Suicide Ideation (SI). Our understanding of the mechanisms underlying this association is limited. The current study examined (1) the mediating role of depression between D/S-IAT and recent SI and (2) the association between SI, D/S-IAT, and clinician evaluation of SI among a clinical sample of adolescents. 148 adolescents aged 10-18 years (69.4% female) from two outpatient clinics were assessed at intake. Participants completed D/S-IAT and self-report measures for recent SI and depression during intake. Findings indicate that depression is a mediator between D/S-IAT and recent SI, controlling for gender, site differences, and past suicidal thoughts and behaviors. D/S-IAT and clinician evaluation were correlated with recent SI but not beyond depression. Our findings highlight the importance of examining the underlying psychological mechanisms regarding the association between D/S-IAT and suicide.
