Risk factors for completed suicide in veterans of peacekeeping: repatriation, negative life events, and marital status

Differences in Beliefs About Suicide by Occupation in a Representative Sample of Adults in the United States, General Social Survey 2002-2021

OBJECTIVE

Beliefs about suicide are important aspects of suicide prevention gatekeeper trainings. This study sought to determine if workers in finance- and legal/judicial-related industries have significantly different levels of suicide acceptability compared to the general US population.

METHOD

Cross-sectional data are from the 2002 to 2021 General Social Survey (GSS). Suicide acceptability was measured with four dichotomous items to which respondents indicated yes/no if they thought someone has the right to end their life in four negative life scenarios. Occupational categories were coded based on U.S. Census Bureau occupation and industry codes. Covariates for multiple logistic regression analyses included age, educational attainment, sex, race, ethnicity, survey year, and religiosity.

RESULTS

Among the 15,166 respondents, 651 people worked in finance-related occupations and 319 people worked in legal/judicial-related occupations. In adjusted models, people in finance-related occupations had greater odds of endorsing suicide as acceptable if one has an incurable disease (aOR = 1.25, 95%CI = 1.03-1.52) and marginally greater odds of endorsing suicide as acceptable if one dishonors their family (aOR = 1.31, 95%CI = 0.99-1.74) than the general adult population. People in legal/judicial-related occupations were more likely to endorse 3 of the 4 suicide acceptability items compared to the general adult population, however these differences were not statistically significant after accounting for demographic factors.

CONCLUSION

Workers in non-clinical industries that frequently see clients during negative life events are prime audiences for gatekeeper trainings but may have entrenched beliefs about suicide acceptability. Research is needed to determine how these beliefs may impact gatekeeper training.

Unlocking the Narrative: Using Text Mining to Reveal the Hidden Factors behind Suicide Related Traffic Crashes

Suicide is the deliberate act of ending a person's own life due to multifarious reasons. In the U.S., suicide is the 10th major cause of death. Nearly 45,000 people died by suicide in 2016 across the nation. It is anticipated that not all traffic crashes can be considered as accidents. Traffic crash related injuries are occasionally considered a means of suicide, and some crashes occur due to the suicidal attempts. These attempts can be made by operators of motor vehicles, jumpers into the pathway of trains, and pedestrians deliberately jumping into the vehicle trajectory. There are a handful of studies that have focused on traffic crashes (both railroad and roadway) related to suicidal incidents. This study aimed to explore the insights associated with suicide related traffic crashes (SRTCs) by collecting traffic data for seven years (2010-2016) from Louisiana. At first, exploratory data analysis was performed to examine the five Ws (who, what, why, when, and where) associated with SRTCs. Later, this study applied text network analysis, which was not performed in any of the previous studies, to provide additional contexts of these crashes. The findings of this study can shed lights on an unexplored arena of transportation safety research.

The Wellbeing of Italian Peacekeeper Military: Psychological Resources, Quality of Life and Internalizing Symptoms

Working as a peacekeeper is associated with the exposure to acute and/or catastrophic events and chronic stressors. Hence, the meager literature about peacekeepers' wellbeing has mainly analyzed Post-Traumatic Stress Disorder (PTSD). This study aims to deep the analysis of the wellbeing of peacekeepers military. Based on the few studies on this population, we hypothesized that Italian peacekeeper military officers and enlisted men (n = 167; 103 males, 6 females, 58 missing) exhibit lower levels of internalizing symptoms (i.e., PTSD, depression, general anxiety, obsessions, and somatization) as compared to a control group (n = 60; 32 males, 28 females). Moreover, we hypothesized that peacekeepers have higher levels of psychological resources (i.e., self-efficacy, self-esteem, social support) and quality of life (i.e., higher life satisfaction and lower general stress). We compared the groups by means of MANOVAs on the subscales of the Psychological Treatment Inventory (PTI; Gori et al., 2015). We found that Italian peacekeepers have lower internalizing symptoms and higher levels of self-efficacy and self-esteem than the control group; however, no statistically significant differences were observed on perceived social support. Finally, peacekeepers have a higher quality of life: scores reflect higher life satisfaction and lower distress than the control group. This study is in line with previous literature supporting the claim that Italian peacekeeper military officers have sufficient psychological resources for coping with the stressful situations implied in peacekeeping missions. Future studies should deepen the analysis of the military's psychological characteristics by comparing war veterans and peacekeeper military.

Suicide Risk by Unit Component among Veterans Who Served in Iraq or Afghanistan

This study assessed the risk of suicide by time since separation from the military for US veterans who served in Iraq or Afghanistan. Suicide risk was assessed by comparing the number of suicides among veterans, when stratified by active vs. reserve/National Guard status to the expected number based on rates of suicide in the US general population. Hazard rates were used to assess suicide risk since the time each veteran separated/deactivated from active duty service. Compared to the US general population, active duty veterans had a 56% increased risk of suicide and reserve/National Guard veterans had a 29% increased risk. Suicide risk decreased as time since separation/deactivation increased for both groups. The risk of suicide for both groups was greatest during the first year of follow-up.

Correlates of suicidality in firefighter/EMS personnel

BACKGROUND

Firefighter and Emergency Medical Services (EMS) personnel experience higher rates of lifetime suicidal ideation and attempts than the general population and other protective service professions. Several correlates of suicidality (alcohol use, depression, posttraumatic stress) have been identified in the literature as applicable to firefighter/EMS populations; however, few studies to date have examined the specific correlates of suicidality (lifetime suicidal ideation and/or attempts) in a firefighter/EMS sample.

METHODS

Participants (N=3036) from a large, urban fire department completed demographic and self-report measures of alcohol dependence, depression, posttraumatic stress disorder (PTSD) symptom severity, and lifetime suicidal ideation and attempts. Participants in this sample performed both firefighter and EMS duties, were predominately male (97%), White (61.6%), and 25-34 years old (32.1%).

RESULTS

Through hierarchical linear regressions, depression (β=.22, p<.05) and PTSD symptom severity (β=.21, p<.05) were significantly associated with lifetime suicidal ideation (R² =17.5). Depression (β=.15, p<.001), and PTSD symptom severity (β=.07, p<.01) were significantly associated with lifetime suicide attempts (R²=5.1).

LIMITATIONS

Several limitations are addressed in the current study. The survey was a self-report pre-existing dataset and lifetime suicidal ideation and attempts were measured using sum scores. Additionally, the disproportionately large sample of males and large, urban setting, may not generalize to female firefighters and members of rural community fire departments.

CONCLUSIONS

The current study highlights the importance of targeting depression and PTSD symptom severity in efforts to reduce suicidality in firefighter/EMS personnel.

International military operations and mental health--A review

BACKGROUND

Volunteering in international military missions has been scrutinized for its effects on mental health. Different kinds of exposures to traumatic events are associated with a variety of mental disorders, mainly heightened rates of post-traumatic stress disorder (PTSD) and alcohol abuse.

AIMS

Based on the literature we discuss risk and protective factors concerning the psychological well-being of soldiers attending to international military operations.

METHODS

A systematic literature search was carried out using relevant search terms to identify the articles for this review.

RESULTS AND CONCLUSIONS

The ability to recognize and treat acute stress reactions during deployments is important. Post-deployment psychosocial support and services have a role in lowering barriers to care, diminishing stigma and also in recognizing individuals who suffer from psychological distress or psychiatric symptoms, to connect them with appropriate care. Further investigation of gender differences and the role of stigmatization is warranted. Most of those participating in international military operations are repatriated without problems, but repeated exposure to combat situations and other stressors may affect mental health in various ways. Stigmatization is still a barrier to care.

Suicidality in Australian Vietnam veterans and their partners

Lifetime suicidality was assessed in a cohort of 448 ageing Australian Vietnam veterans and 237 female partners during in-person structured psychiatric interviews that permitted direct comparison with age-sex matched Australian population statistics. Relative risks for suicidal ideation, planning and attempts were 7.9, 9.7 and 13.8 times higher for veterans compared with the Australian population and for partners were 6.2, 3.5 and 6.0 times higher. Odds ratios between psychiatric diagnoses and suicidality were computed using multivariate logistic regression, and suicidality severity scores were assigned from ideation, planning and attempt, and analysed using ordinal regression. PTSD, depression alcohol disorders, phobia and agoraphobia were prominent predictors of ideation, attempts and suicidal severity among veterans, while depression, PTSD, social phobia and panic disorder were prominent predictors among partners. For veterans and their partners, PTSD is a risk factor for suicidality even in the presence of other psychiatric disorders, and is stronger in Vietnam veterans than their partners.

Caregivers of veterans with "invisible" injuries: what we know and implications for social work practice

Today, as a result of the longest volunteer-fought conflict in U.S. history, there are many wounded coming home not only with posttraumatic stress disorder (PTSD), but also with traumatic brain injury (TBI), which together have been called the "signature" or "invisible" injuries of the Iraq and Afghanistan wars. Caregivers are an important part of their recovery, yet little is known about them, as previous research on caregivers mostly focused on geriatric populations. According to one estimate 275,000 to 1 million people are currently caring or have cared for loved ones who have returned from Iraq and Afghanistan. These caregivers are unique in that they are younger, some with children, and they are caring for a unique under-studied population for longer periods of time. This article summarizes literature on caregivers of veterans who suffer from PTSD, TBI, or both; provides a theoretical framework; and discusses implications for social workers in assisting caregivers and their families.

A prospective study of suicidal ideation in posttraumatic stress disorder: the role of perceptions of defeat and entrapment

OBJECTIVES

This study aimed to provide the first prospective test of the ability of defeat and entrapment to predict suicidal ideation in posttraumatic stress disorder (PTSD) after controlling for the effects of PTSD severity, comorbid depressive symptoms, and hopelessness on suicidal ideation.

METHODS

Participants were 52 individuals diagnosed with PTSD. Baseline and follow-up assessments were 13 to 15 months apart. Defeat and entrapment were conceptualized and analyzed as a unique construct (defeat/entrapment) in this study. Multiple regression analysis was applied to examine the predictive effects of defeat/entrapment on suicidal ideation.

RESULTS

Defeat/entrapment scores predicted changes in the levels of suicidal ideation at follow-up while controlling for baseline suicidal ideation, PTSD severity, comorbid depressive symptoms, and hopelessness.

CONCLUSIONS

These outcomes provide support to contemporary models of suicidality that suggest that defeat/entrapment is a strong predictor of suicidality in PTSD.

Predictors for suicidal ideation after occupational injury

Risk of suicide has been associated with trauma and negative life events in several studies. Our aim was to investigate the prevalence and risk factors of suicidal ideation, and the population attributable risk among workers after occupational injuries. We investigated workers who had been hospitalized for ≧3 days after occupational injuries between February 1 and August 31, 2009. A self-reported questionnaire including demographic data, injury condition, and the question of suicidal ideation was sent to 4498 workers at 3 months after their occupational injury. A total of 2001 workers (45.5%) completed the questionnaires and were included in final analysis. The prevalence of reporting suicidal ideation was 8.3%. After mutual adjustment, significant risk factors for suicidal ideation higher than "serious" in a self-rated severity scale (adjusted odds ratio, aOR=2.31; adjusted population attributable risk, aPAR=34.7%), total hospital stay for 8 days or longer (OR=1.98; aPAR=20.5%), intracranial injury (OR=2.30; aPAR=10.2%), and marriage status of being divorced/separated/widowed (OR=2.70; aPAR=10.0%). Three months after occupational injury, a significant proportion of workers suffered from suicidal ideation. Significant predictors of suicidal ideation after occupational injury included broken marriage, intracranial injury, injury severity, and total hospital stay. Identification of high risk subjects for early intervention is warranted.

Suicide risk and precipitating circumstances among young, middle-aged, and older male veterans

OBJECTIVES

The purpose of this study was to evaluate the risk of suicide among veteran men relative to nonveteran men by age and to examine the prevalence of suicide circumstances among male veterans in different age groups (18-34, 35-44, 45-64, and ≥ 65 years).

METHODS

Data from the National Violent Death Reporting System (2003-2008) were used to calculate age-specific suicide rates for veterans (n = 8440) and nonveterans (n = 21,668) and to calculate the age-stratified mortality ratio for veterans. Multiple logistic regression was used to compare health status, stressful life events preceding suicide, and means of death among young, middle-aged, and older veterans.

RESULTS

Veterans were at higher risk for suicide compared with nonveterans in all age groups except the oldest. Mental health, substance abuse, and financial and relationship problems were more common in younger than in older veteran suicide decedents, whereas health problems were more prevalent in the older veterans. Most male veterans used firearms for suicide, and nearly all elderly veterans did so.

CONCLUSIONS

Our study highlighted heightened risk of suicide in male veterans compared with nonveterans. Within the veteran population, suicide might be influenced by different precipitating factors at various stages of life.

Insecure attachment is an independent correlate of objective sleep disturbances in military veterans

BACKGROUND

Sleep disturbances and interpersonal problems are highly prevalent in military veterans with post-traumatic stress disorder (PTSD) and are associated with substantial comorbidities and increased healthcare costs. This study examines the association between interpersonal attachment styles and sleep in a high-risk cohort of military veterans with PTSD symptoms.

METHODS

Participants were 49 military veterans (85% male) enrolled in a treatment study of combat-related sleep disturbances. Data were collected at pre-treatment baseline. Attachment anxiety and avoidance, clinical characteristics, and subjective sleep quality were characterised via self-report. Polysomnographic sleep measures were averaged from two nights of in-laboratory sleep studies and included: visually scored duration and continuity, the percentage of stage 3+4 sleep and rapid eye movement (REM) sleep, and quantitative electroencephalographic (QEEG) measures of delta and beta power during NREM and REM sleep. Linear regressions evaluated the relationship between attachment styles and sleep with adjustment for demographics, and PTSD and depressive symptoms.

RESULTS

Greater attachment anxiety was associated with reduced percentage of stage 3+4 sleep, (β=-0.36, p<0.05) and increased relative beta power during NREM sleep (β=0.40, p<0.05). By contrast, greater attachment avoidance was positively associated with delta power during NREM and REM sleep (β=0.35 and 0.38, respectively, p<0.05).

CONCLUSIONS

These findings suggest specific effects of interpersonal styles on physiological sleep measures. Elucidating both the neurobiological and psychological correlates of PTSD-related sleep disturbances is critical for developing future targeted intervention efforts aimed at reducing the burden of PTSD.

Does PTSD moderate the relationship between social support and suicide risk in Iraq and Afghanistan War Veterans seeking mental health treatment?

OBJECTIVE

This study examined posttraumatic stress disorder (PTSD) as a potential moderating variable in the relationship between social support and elevated suicide risk in a sample of treatment-seeking Iraq and Afghanistan War Veterans.

METHOD

As part of routine care, self-reported marital status, satisfaction with social networks, PTSD, and recent suicidality were assessed in Veterans (N=431) referred for mental health services at a large Veteran Affairs Medical Center. Logistic regression analyses were conducted using this cross-sectional data sample to test predictions of diminished influence of social support on suicide risk in Veterans reporting PTSD.

RESULTS

Thirteen percent of Veterans were classified as being at elevated risk for suicide. Married Veterans were less likely to be at elevated suicide risk relative to unmarried Veterans and Veterans reporting greater satisfaction with their social networks were less likely to be at elevated risk relative to Veterans reporting lower satisfaction. Satisfaction with social networks was protective for suicide risk in PTSD and non-PTSD cases, but was significantly less protective for veterans reporting PTSD.

CONCLUSIONS

Veterans who are married and Veterans who report greater satisfaction with social networks are less likely to endorse suicidal thoughts or behaviors suggestive of elevated suicide risk. However, the presence of PTSD may diminish the protective influence of social networks among treatment-seeking Veterans.

The interpersonal theory of suicide

Suicidal behavior is a major problem worldwide and, at the same time, has received relatively little empirical attention. This relative lack of empirical attention may be due in part to a relative absence of theory development regarding suicidal behavior. The current article presents the interpersonal theory of suicidal behavior. We propose that the most dangerous form of suicidal desire is caused by the simultaneous presence of two interpersonal constructs-thwarted belongingness and perceived burdensomeness (and hopelessness about these states)-and further that the capability to engage in suicidal behavior is separate from the desire to engage in suicidal behavior. According to the theory, the capability for suicidal behavior emerges, via habituation and opponent processes, in response to repeated exposure to physically painful and/or fear-inducing experiences. In the current article, the theory's hypotheses are more precisely delineated than in previous presentations (Joiner, 2005), with the aim of inviting scientific inquiry and potential falsification of the theory's hypotheses.

Suicide risk factors in the professional military personnel in the Army of Serbia

Background/Aim. Recognition of suicide risk factors is important in taking adequate suicide preventive measures, Suicide Prevention Program for Professional Military Personnel (PMP) implemented in the Army of Serbia in 2003. The aim of our study was to establish suicide risk factors in PMP of the Army of Serbia. Methods. Analysis of suicide risk factors in PMP was carried out on the basis of data obtained by psychological suicide autopsy. The controls were demographically similar psychiatric outpatients with no history of suicidal behavior. A descriptive statistics method was used for risk factors analysis. The t-test was used for testing statistical hypotheses. Results. A total of 30 PMP, aged 22-49 years (30.53 ? 6.24 on average) committed suicide within the period 1998-2007. Distal suicide risk factors in PMP were considered to be not being married, psychiatric heredity, having no outpatient psychiatric treatment, gambling, regular physical practice (bodybuilding), less transfer to a different post, low motivation for military service (p < 0.001), not having children, parental loss in early childhood, alcohol abuse (p < 0.005), low salary (p < 0.01) uncompleted military school, debts in the family (p < 0.05). The commonest proximal suicide risk factors were: actual family problems (36.6%), actual mental problems (13.3%), burnout (13.3%), negative balance of accounts (13.3%), professional problems (6.7%), behavioral model while for 10.0% PMP suicide risk factors could not be established. Conclusion. According to the presence of multiple suicide risk factors, Suicide Prevention Program for PMP in the Army of Serbia is directed to the prevention of both proximal and distal suicide risk factors.

Overcoming the fear of lethal injury: evaluating suicidal behavior in the military through the lens of the Interpersonal-Psychological Theory of Suicide

Suicide rates have been increasing in military personnel since the start of Operation Enduring Freedom and Operation Iraqi Freedom, and it is vital that efforts be made to advance suicide risk assessment techniques and treatment for members of the military who may be experiencing suicidal symptoms. One potential way to advance the understanding of suicide in the military is through the use of the Interpersonal-Psychological Theory of Suicide. This theory proposes that three necessary factors are needed to complete suicide: feelings that one does not belong with other people, feelings that one is a burden on others or society, and an acquired capability to overcome the fear and pain associated with suicide. This review analyzes the various ways that military service may influence suicidal behavior and integrates these findings into an overall framework with relevant practical implications. Findings suggest that although there are many important factors in military suicide, the acquired capability may be the most impacted by military experience because combat exposure and training may cause habituation to fear of painful experiences, including suicide. Future research directions, ways to enhance risk assessment, and treatment implications are also discussed.

Suicide after leaving the UK armed forces--a cohort study

BACKGROUND

Few studies have examined suicide risk in individuals once they have left the military. We aimed to investigate the rate, timing, and risk factors for suicide in all those who had left the UK Armed Forces (1996-2005).

METHODS AND FINDINGS

We carried out a cohort study of ex-Armed Forces personnel by linking national databases of discharged personnel and suicide deaths (which included deaths receiving either a suicide or undetermined verdict). Comparisons were made with both general and serving populations. During the study period 233,803 individuals left the Armed Forces and 224 died by suicide. Although the overall rate of suicide was not greater than that in the general population, the risk of suicide in men aged 24 y and younger who had left the Armed Forces was approximately two to three times higher than the risk for the same age groups in the general and serving populations (age-specific rate ratios ranging from 170 to 290). The risk of suicide for men aged 30-49 y was lower than that in the general population. The risk was persistent but may have been at its highest in the first 2 y following discharge. The risk of suicide was greatest in males, those who had served in the Army, those with a short length of service, and those of lower rank. The rate of contact with specialist mental health was lowest in the age groups at greatest risk of suicide (14% for those aged under 20 y, 20% for those aged 20-24 y).

CONCLUSIONS

Young men who leave the UK Armed Forces were at increased risk of suicide. This may reflect preservice vulnerabilities rather than factors related to service experiences or discharge. Preventive strategies might include practical and psychological preparation for discharge and encouraging appropriate help-seeking behaviour once individuals have left the services.

Traumatic stress and suicidal ideation in Norwegian male peacekeepers

To investigate the association between war zone stress exposure during international military operations and later suicidal ideation, a follow-up study of 1172 Norwegian male peacekeepers was conducted 7 years, on average, after redeployment. Suicidal ideation was reported in 6% of the veterans, while it was reported in 17% of the subsample of those who were prematurely repatriated. Suicidal ideation was significantly associated with service stress exposure level, even when background factors, repatriation status, negative life events, social support, alcohol consumption, and marital and occupational status were controlled for. Results indicate that the association between service stress exposure and suicidal ideation was mediated by posttraumatic stress symptoms and general mental health problems combined.
