Characteristics of suicide attempts associated with lethality and method: A latent class analysis of the Military Suicide Research Consortium

Increases in suicidal thoughts disclosure among adults in France from 2000 to 2021

BACKGROUND

The objective of the study was to investigate the prevalence of suicidal ideation disclosure over the past two decades in nationally representative samples of the general population, and to identify factors associated with disclosure.

METHODS

Data were drawn from consecutive nationally representative cross-sectional Health Barometer surveys. The 2000, 2005, 2010, 2014, 2017, and 2021 waves were pooled to examine disclosure among those who reported 12-month suicidal ideation. Logistic regressions were performed to identify factors associated with the odds of disclosure.

RESULTS

Across all waves (n = 124,124), 6014 of adults (4.7 %) reported 12-month suicidal ideation, and among them, 49.7 % talked to someone about it. Disclosure was 39 % in 2000, 44.6 % in 2005, 49.9 % in 2010, 52.8 % in 2014, 47.2 % in 2017, and 64.8 % in 2021. Female gender, a prior suicide attempt, higher education, inactive status, and younger age were associated with significantly greater odds of disclosure. Each survey wave was also associated with a greater likelihood of disclosure when compared to 2000, 1.31 (95 % CI, 1.08-1.59) in 2005, 1.69 (95 % CI, 1.38-2.07) in 2010, 1.89 (95 % CI, 1.52-2.34) in 2014, 1.47 (95 % CI, 1.21-1.79) in 2017, and 2.99 (95 % CI, 2.43-3.68) in 2021.

LIMITATIONS

Cross-sectional surveys.

CONCLUSIONS

In the general population of France, adults with suicidal ideation were increasingly more likely to disclose their ideation to someone in recent years. Factors associated with odds of disclosure should inform national suicide prevention strategies to identify subgroups who remain less likely than others to disclose their ideation.

Examining the association between aggression and suicide attempts among army soldiers

BACKGROUND

Suicide is a major concern among active-duty military personnel. Aggression represents a salient risk factor for suicide among civilians, yet is relatively understudied among military populations. Although several theories posit a relation between aggression and suicide with putative underlying mechanisms of social isolation, access to firearms, and alcohol use, researchers have yet to test these potential mediators. This study uses rich, longitudinal data from the Army Study to Assess Risk and Resilience (STARRS) Pre/Post Deployment Study (PPDS) to examine whether aggression longitudinally predicts suicide attempts and to identify mediators of this association.

METHODS

Army soldiers (N = 8483) completed assessments 1 month prior to deployment and 1, 2-3, and 9-12 months post-deployment. Participants reported on their physical and verbal aggression, suicide attempts, social network size, firearm ownership, and frequency of alcohol use.

RESULTS

As expected, pre-deployment aggression was significantly associated with suicide attempts at 12-months post-deployment even after controlling for lifetime suicide attempts. Social network size and alcohol use frequency mediated this association, but firearm ownership did not.

CONCLUSIONS

Findings further implicate aggression as an important suicide risk factor among military personnel and suggest that social isolation and alcohol use may partially account for this association.

Are veterans willing to assist with firearm safety for suicide prevention?

Veterans in the United States are affected by suicide at higher rates than the general population. This may be due to a higher probability for veterans to use more lethal methods of suicides such as firearms. While veterans often decline to disclose suicidal tendencies to healthcare providers, they show higher connectedness and willingness to heed the advice of peers. Considering this information, it is important to analyze how veteran peers could assist in a suicidal crisis. Veteran responses (n = 1,247) to the Gatekeeper Behavior Scale (GBS) and Firearm Safety Scale (FSS) were analyzed to determine predictive traits of willingness to assist a peer securely store or disable firearms during a suicidal crisis. Results show that veterans are willing to assist in securing firearms to prevent suicide death but are more willing to do so by locking, removing or disabling the firearms than storing them with law enforcement. Older veterans were also more likely to report a willingness to intervene than their younger peers. Of the GBS predictors, only the Likeliness to Help subscale predicted a willingness to intervene with firearm safety. Recommendations for training and interventions that further encourage helping behavior during suicidal episodes are discussed.

Suicidal ambivalence: A scoping review

BACKGROUND

Suicidal ambivalence is considered a characteristic condition of suicidal individuals. At the same time, there is a lack of a uniform definition, conception and assessment of suicidal ambivalence. On this background, the current scoping review aims to explore the extent, range, and nature of research activity on suicidal ambivalence and to summarize research findings.

METHODS

A systematic literature search was conducted in four different databases (PubMed, Psychinfo, Web of Science, and Google Scholar) using an array of search terms (e.g., ambivalence, internal suicide debate, reasons for living and reasons for dying, wish to live and wish to die).

RESULTS

In total, 28 articles published between 1977 and 2023 were included in the scoping review. The study situation lacks a clear definition, conceptualization and operationalization of suicidal ambivalence. Nonetheless, suicidal ambivalence is a common experience in persons contemplating suicide and suicidal ambivalence seems to be present before, during and after a suicide attempt. Suicidal ambivalence is associated with diverse markers of negative/positive mental health as well as suicidal ideation and behavior.

CONCLUSION

Results point to the relevance of suicidal ambivalence. At the same time, there are large gaps in knowledge about the development, impact and therapeutic responsiveness of suicidal ambivalence.

Suicide risk profiles among service members and veterans exposed to suicide

OBJECTIVES

Rates of suicide exposure are high among service members and Veterans and are especially concerning given the link between suicide exposure and subsequent suicide risk. However, to date, it is unclear which individuals who are exposed to suicide are subsequently at high risk for suicide. Latent profile analysis (LPA) can provide information on unique risk profiles and subgroups of service members and Veterans who have higher suicide risk after suicide exposure, which has not yet been empirically studied. The purpose of this study was to utilize LPA to identify subgroups of service members and Veterans who are at the highest risk for suicidal thoughts and behaviors following suicide exposure.

METHODS

We analyzed data using LPA from 2570 service members and Veterans (82.1% male, 69.5% White, and 12.1% Latino/a/x) who completed the Military Suicide Research Consortium's Common Data Elements, a battery of self-report suicide-related measures. Psychopathology, substance use, mental health service utilization, interpersonal theory of suicide, and suicide exposure variables were used to validate classes.

RESULTS

Three latent classes emerged from analyses, one low-risk class and two-high risk classes with differing profile compositions (one primarily differentiated by anxiety symptoms and one differentiated by substance use).

CONCLUSION

Class-specific recommendations for suicide prevention efforts will be discussed.

Situational stress and suicide attempt behavior in Army soldiers and veterans: Insights from the Army Study to Assess Risk and Resilience in Servicemembers-Longitudinal Study

INTRODUCTION

Prevention of suicide-related behaviors is considered a top clinical priority within the Departments of Veterans Affairs and Defense. Despite previous literature attesting to the likely importance of situational stress as a key correlate of acute changes in suicide risk, longitudinal research into associations between situational stress and suicide-related outcomes among military personnel has been relatively limited.

METHODS

The current study examined associations between situational stress, recent suicide attempt, and future suicide attempt using data from 14,508 Army soldiers and recently discharged veterans enrolled in the Army Study to Assess Risk and Resilience in Servicemembers-Longitudinal Studies (STARRS-LS).

RESULTS

Recent situational stress was more common among recently discharged veterans (vs. soldiers), those with a recent suicide attempt (vs. those without), and those with a subsequent suicide attempt (vs. those without). Job loss was more closely associated with suicide attempts among soldiers, whereas financial crisis, police contact, and death, illness, or injury of close others were more closely associated with suicide attempts among recently discharged veterans.

CONCLUSION

Findings further highlight situational stress as a salient risk factor for suicide-related outcomes among military personnel, particularly among recently discharged veterans. Implications for screening and treatment of at-risk military personnel are discussed.

Disclosure of suicidal ideation and behaviours: A systematic review and meta-analysis of prevalence

Disclosure of suicidal ideation and behaviours, defined as thoughts, plans, or attempts, to other people provides opportunity for intervention and prevention. This study is the first to meta-analyze all available studies to estimate the prevalence of disclosure, to whom people disclose, and examine factors that influence disclosure. Databases were searched for studies reporting samples of people who had experienced suicidal ideation or behaviours (including those who had died by suicide) and whether they had disclosed this. Almost 100 studies (k = 94, N participants = 1,044,629) were included in the overall prevalance analysis. The results showed less than half of people disclosed suicidal ideation or behaviour: 45.9% (95%CI 41.9-49.9%, PI 12.3-81.8%; k = 94). High heterogeneity, common to prevalence studies, was found (Q[93] = 130,584, p < .001; I² = 99.9%). No publication bias was detected. Removing outliers did not change the prevalence estimate, but provided tighter prediction intervals: 45.6% (95%CI 43.4-47.9%, PI 35.8-55.7%; k = 33). Disclosure was related to higher prevalence of psychiatric disorders, female gender, and a longer timeframe of suicidal ideation or behaviour. Prevalence of disclosure was lower among people who died by suicide, relative to community samples, and lower when reported verbally rather than written online. Disclosure, and proportions of disclosures, to family members, was numerically higher than to friends or professionals, but could not be directly compared. In conclusion, between 50 and 60% of people do not disclose their suicidal ideation and behaviours to other people, and therefore remain unidentified and potentially untreated.

Feasibility of recruitment and retention in a remote trial of gatekeeper training for close supports of military veterans: Mixed methods study

Background

VA S.A.V.E. (Signs; Ask; Validate; Encourage/Expedite) is a gatekeeper training, designed to teach individuals how to identify and assist military veterans at risk for suicide. The aim of this pilot was to determine feasibility, barriers, and facilitators of recruitment and retention in a remote trial of VA S.A.V.E.

Methods

We recruited close supports (family and friends) of veterans through Facebook sponsored ads, automatically randomized them to VA S.A.V.E. or an unrelated video training, and followed them for six months. A subgroup completed interviews, and we used a mixed methods framework to integrate quantitative and qualitative findings.

Results

Of 214 participants, 61% were spouses or partners of veterans and 48% knew at least one veteran who had died by suicide. Of the three a priori feasibility benchmarks, two were achieved (enrollment, on average, of twenty participants per week and less than 50% loss to follow-up at the 6-month study endpoint) and one was not (enrollment of at least 50% of eligible individuals). There were three barriers (generic ads, ad text referring to "research," and Facebook as an ad platform) and five facilitators (audience segmentation focused on veterans' family members and friends, an urgent call to action to help a veteran, prior exposure to suicide, emphasizing the benefit of receiving training, and using a university as the campaign messenger) to study participation.

Conclusion

A fully remote trial of VA S.A.V.E. gatekeeper training was feasible in a population of close supports of veterans. Several strategies may further enhance study participation.
