Factors Associated with Suicidality Among a National Sample of Transgender Veterans

Correlates of past‐year suicidal ideation and lifetime suicide risk among a national sample of transgender veterans were examined. An online, convenience sample of 212 U.S. transgender veterans participated in a cross‐sectional survey in February–May 2014. We evaluated associations between sociodemographic characteristics, stigma, mental health, and psychosocial resources with past‐year suicidal ideation and lifetime suicide plans and attempts. Participants reported high rates of past‐year suicidal ideation (57%) as well as history of suicide plan or attempt (66%). Transgender‐related felt stigma during military service and current posttraumatic stress disorder and depressive symptoms were associated with suicide outcomes as were economic and demographic factors.     

Recent suicidal ideation and suicide attempts in a large-scale survey of the U.S. Air Force: prevalences and demographic risk factors

One-year prevalences of self-reported noteworthy suicidal ideation and nonfatal suicide attempts were assessed in a large sample of U.S. Air Force active duty members (N = 52,780). Participants completed the 2006 Community Assessment, which was conducted online. Over 3% of male and 5.5% of female participants reported having experienced noteworthy suicidal ideation during the previous year, and 8.7% of those with ideation reported a recent suicide attempt. Demographic factors predicting significantly increased risk for suicidal ideation included female gender, low rank, and non-Christian religious affiliation; unmarried men were also at increased risk. Groups that were at increased risk for nonfatal suicide attempts included low-ranking men and Hispanic women. Implications for prevention efforts are discussed.     

A Preliminary Study for Exploring Different Sources of Guilt in a Sample of Veterans Who Sought Chaplaincy Services

Limited research has suggested that experiencing guilt may contribute to the risk of suicidal behavior in some veteran populations. Using data collected by chaplains, this study compared the frequency with which 94 veterans with a history of suicide ideation experienced guilt relative to 670 veterans without a history of ideation. We then compared main sources of guilt reported by ideators and nonideators. Ideators reported experiencing guilt significantly more often than nonideators. No differences were noted for the source of guilt among those who reported frequently experiencing this emotion. Ideators with an infrequent experience of guilt significantly more often named life and the military as the main source of this emotion. Clinicians should be mindful of the need to appropriately assess for and address guilt among veterans at increased risk of suicide. A variety of sources, not limited only to military experiences, may contribute to a veteran’s sense of guilt.     

Current and Military‐Specific Gender Minority Stress Factors and Their Relationship with Suicide Ideation in Transgender Veterans

Research suggests the prevalence of suicide ideation and suicide attempts in the transgender veteran community may be upwards of 20 times higher than nontransgender veterans, who are known to be at increased risk than the general US population. This study aimed to understand the potential influence of external and internal minority stress experienced during and after military service on past‐year and recent suicide ideation in a sample of 201 transgender veterans. Nonparametric bootstrapping analyses indicated past‐year transgender‐specific discrimination and rejection (external minority stress) indirectly predicted frequency of both past‐year and past 2‐week suicide ideation through past‐year shame related to gender identity (internal minority stress). This result was significant when controlling for symptoms of depression and demographics. Similar patterns emerged when examining relationships among military external and internal minority stress on suicide outcomes. These results suggest that attempts to reduce both the experience and impact of minority stressors related to gender identity during and after military service may be an important avenue for suicide prevention.     

State of Innovation in Suicide Intervention Research with Military Populations

A systematic search was performed to identify active, externally funded randomized controlled trials (RCTs) that target suicidal ideation or behavior as a primary or secondary outcome among U.S. military service members, guard–reservists, and veterans. Twenty‐three studies were identified, most funded by the U.S. Department of Defense or U.S. Department of Veterans Affairs. Several innovations were identified based on departures from or modernizations of usual practices and included the targeting of suicide deaths or attempts as primary outcome, delivery of interventions through technology and/or outside clinical settings, and examinations of rarely studied treatments.     

Increased Risk of Suicidal Ideation in Smokers and Former Smokers Compared to Never Smokers: Evidence from the Baltimore ECA Follow‐Up Study

The incidence rate of suicidal ideation among current and former smokers versus never smokers is not known. In this study, the age‐adjusted incidence of suicidal ideation was highest among current smokers, followed by former, then never smokers. The adjusted hazard for suicide ideation was 2.22 (95%CI = 1.48, 3.33) and 1.19 (95%CI = 0.78, 1.82) for current and former smokers, respectively, compared to never smokers. Results indicate that current smokers have increased risks of suicidal ideation above and beyond the risk for never and former smokers regardless of age, gender, history of depressive disorder or anxiety symptoms, and alcohol abuse/dependence. Smoking cessation might be beneficial for some suicide prevention efforts.     

Emotion Dysregulation and Military Suicidality Since 2001: A Review of the Literature

Policy makers and researchers have worked to explain the perplexing rise in U.S. military suicides since 2001, with little progress in explaining this widespread phenomenon. This article synthesizes several literatures to highlight the role of emotion dysregulation in military suicidality. After considering advances in suicidal ideation‐to‐action frameworks and the factors that contribute to the prevalence of emotion dysregulation in the modern U.S. military, it explores how military service provides for two distinct circumstances in which such emotion dysregulation may facilitate the transition from suicidal ideation to behavior. The first circumstance is high distress tolerance, wherein the effects of disproportionately high rates of adverse childhood experiences (ACEs) among service‐members may increase vulnerability to suicidal behavior. The second circumstance is preexisting acquired capability with lethal means paired with executive functioning degradation. Empirically associated with military environments, such degradation may undermine the effectiveness of top‐down emotion regulation strategies—thereby allowing acquired familiarity with lethal means to assist the transition from suicidal ideation to action. Thus, emotion dysregulation’s unique relationship with the U.S. military may help to explain the powerful correlation between service and suicide since 2001—suggesting that enhancing emotion regulation skills may present a key leverage point for effectively addressing the issue.     

Suicidal ideation and attitudes toward suicide

Although hopelessness and depression are known risk factors for suicide, most individuals who are hopeless or depressed never make a suicide attempt. In this study, we tested the hypothesis that college students' (n = 230) attitudes toward suicide (the degree to which they see it as an acceptable option under some circumstances) would moderate the link between both hopelessness and depressive symptoms and their levels of suicidal ideation. This moderation hypothesis was supported, but only among men. Specifically, among men, levels of hopelessness and depressive symptoms were significantly related to suicidal ideation among only those with relatively positive attitudes toward suicide.     

The Sexual Harassment–Suicide Connection in the U.S. Military: Contextual Effects of Hostile Work Environment and Trusted Unit Leaders

Sexual harassment has been associated with suicidal behaviors, and with the rise in suicides in the U.S. military, sexual harassment's role in suicide has been of growing interest. Lacking are studies that examine group‐ or unit‐level variables in the relationship of sexual harassment to suicidal behaviors (thoughts, plans, and attempts). In this study, survey data from soldiers (12,567 soldiers in 180 company‐sized units) who completed the Unit Risk Inventory administered during calendar year 2010 were analyzed using hierarchical linear modeling. At the individual level, sexual harassment was associated with a fivefold increase for risk of suicide. Reporting that leaders could be trusted was associated with a decreased suicide risk by about one‐third. There was no statistically significant interaction between sexual harassment and trusted leaders in predicting the suicidal behaviors. At the group level, units or companies having higher levels of sexual harassment also had soldiers three times more at risk for suicide. A cross‐leveling effect was also observed: Among units having higher levels of sexual harassment, the negative correlation (buffering effect of unit leaders on suicidal behaviors) was diminished. Implications of findings for preventing sexual harassment and suicide risk are discussed.     

Does Reintegration Stress Contribute to Suicidal Ideation Among Returning Veterans Seeking PTSD Treatment?

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well‐established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed.     

Defeat and Entrapment in Bipolar Disorder: Exploring the Relationship with Suicidal Ideation from a Psychological Theoretical Perspective

Contemporary psychological theoretical models of suicide hypothesize that defeat and entrapment underlie the development of suicidal ideation. This hypothesis has never been tested in people who experience bipolar disorder. Regression analysis revealed that defeat and entrapment significantly predicted suicidal ideation at 4‐month follow‐up. The relationship between defeat and suicidal ideation was mediated by total entrapment and internal entrapment, but not external entrapment. Results suggest that perceived defeat and entrapment underlie the development of prospective suicidal ideation in bipolar disorder. Findings could potentially improve the assessment of suicide risk in people who experience bipolar disorder.     

Risk Factors for Attempting Suicide in Prisoners

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality, psychiatric, and substance abuse factors.     

Nonlinear Change Processes During Psychotherapy Characterize Patients Who Have Made Multiple Suicide Attempts

Research suggests that multiple suicide attempters experience considerable variability in suicide ideation and longer‐duration suicidal crises, which suggests the possibility of two states of stability (one low risk and one high risk). To date, however, few studies have examined nonlinear change processes in suicide ideation among patients. In a sample of 76 active duty U.S. Army soldiers receiving brief cognitive behavioral therapy for acute suicide risk, we examined differences in the ebb and flow of suicide ideation among multiple attempters, first‐time attempters, and ideators. Results indicated that multiple attempters were characterized by two states of stability corresponding to low and high intensity suicide ideation; these states were separated by a region of instability corresponding to moderate intensity suicide ideation. In contrast, ideators and first‐time attempters were characterized by only a single state of stability corresponding to low intensity suicide ideation. Among patients who have made multiple suicide attempts, suicide ideation may function as a bimodal rather than a continuous construct.     

Lifetime Suicidal Behaviors and Career Characteristics Among U.S. Army Soldiers: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

The current report presents data on lifetime prevalence of suicide ideation and nonfatal attempts as reported by the large representative sample of U.S. Army soldiers who participated in the Consolidated All‐Army Survey of the Army Study to Assess Risk and Resilience in Servicemembers (N  =  29,982). We also examine associations of key Army career characteristics with these outcomes. Prevalence estimates for lifetime suicide ideation are 12.7% among men and 20.1% among women, and for lifetime suicide attempts are 2.5% and 5.1%, respectively. Retrospective age‐of‐onset reports suggest that 53.4%–70% of these outcomes had preenlistment onsets. Results revealed that, for both men and women, being in the Regular Army, compared with being in the National Guard or Army Reserve, and being in an enlisted rank, compared with being an officer, is associated with increased risk of suicidal behaviors and that this elevated risk is present both before and after joining the Army.     

Risk and Protective Factors that Distinguish Adolescents Who Attempt Suicide from Those Who Only Consider Suicide in the Past Year

Data from the 2010 Minnesota Student Survey was analyzed to identify risk and protective factors that distinguished adolescents across three groups: no suicidality, suicidal ideation only, and suicide attempt. The population‐based sample included 70,022 students in grades 9 and 12. Hopelessness and depressive symptoms emerged as important risk factors to distinguish youth who reported suicidal ideation or behavior from those without a history of suicidality. However, these factors were not as important in differentiating adolescents who attempted suicidal from those who considered suicide but did not act on their thoughts. Instead, for both genders, self‐injury represented the most important factor to distinguish these youth. Other risk factors that differentiated the latter groups, but not the former groups, for males were dating violence victimization and cigarette smoking, and for females was a same‐sex sexual experience. Running away from home also seemed to increase the risk of a suicide attempt among youth in this study. Parent connectedness and academic achievement emerged as important protective factors to differentiate all the groups, yet neighborhood safety appeared to protect against the transition from suicidal thoughts to behavior. Findings from this study suggest risk and protective factors practitioners should target in clinical assessments and intervention programs to help prevent suicidal behavior among youth at greatest risk.     

Trajectories of Suicide Ideation,Nonsuicidal Self‐Injury,and Suicide Attempts in a Nonclinical Sample of Military Personnel and Veterans

Nonsuicidal self‐injury (NSSI) is a risk factor for suicide attempts, but little is known about NSSI among military personnel and veterans, or about the temporal sequencing of NSSI relative to suicide ideation and attempts. This study evaluates trajectories of suicide ideation, NSSI, and suicide attempts in a sample of 422 military personnel and veterans. Of those with a history of NSSI, 77% also experienced suicide ideation. Suicide ideation emerged before NSSI (67%) more often than the reverse (17%). Of those with a history of suicide attempt, 41% also engaged in NSSI. NSSI emerged prior to the first suicide attempt (91%) more often than the reverse (9%). The length of time from suicide ideation to suicide attempt was longer for those who first engaged in NSSI (median = 3.5 years) compared with those who did not engage in NSSI (median = 0.0 years), Wald χ²(1) = 11.985, p = .002. Age of onset was earlier for participants reporting NSSI only compared with those reporting both NSSI and suicide attempts (16.71 vs. 22.08 years), F(1, 45) = 4.149, p = .048. NSSI may serve as a “stepping stone” from suicide ideation to attempts for 41% of those who attempt suicide.     

Prior Mental Disorders and Lifetime Suicidal Behaviors Among US Army Soldiers in the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

We report on associations of retrospectively reported temporally prior mental disorders and Army career characteristics with subsequent first onset of suicidal behaviors in a large, representative sample of US Army soldiers who participated in the Consolidated All‐Army Survey of the Army Study to Assess Risk and Resilience in Servicemembers (N = 29,982). Results reveal that among men and women, all self‐reported lifetime disorders measured (some assessed with screening scales) are associated with subsequent onset of suicide ideation. Among men, three disorders characterized by agitation and impulsiveness (intermittent explosive disorder, panic disorder, and substance disorders) predict the transition from suicide ideation to attempt. For both men and women, being in the Regular Army (vs. National Guard or Army Reserve) predicts suicide attempts in the total sample. For men, a history of deployment and junior rank are predictors of suicide attempts after adjusting for preenlistment disorders but not accounting for pre‐ and postenlistment disorders, suggesting that postenlistment disorders account for some of the increased suicide risk among these career characteristics. Overall, these results highlight associations between mental disorders and suicidal behaviors, but underscore limitations predicting which people with ideation attempt suicide.     

Effect of Socioeconomic Status on the Linkage Between Suicidal Ideation and Suicide Attempts

Previous suicide attempts are a leading risk factor for completed suicide. To identify specific characteristics of those at high risk for attempts, we investigated associations with socioeconomic status (SES). Data from the 2013 Korean Community Health Survey (KCHS) included adults who reported suicidal ideation (N = 220,245). Attempts in the past 12 months were assessed. Associations of demographic, socioeconomic, and suicide‐related behavioral factors were analyzed using multiple logistic regression. Among those with suicidal ideation, 862 (3.9%) had attempted suicide. After stratification by age and gender, results showed that low education and unemployed young adult men and women had significantly higher rates of attempts. The lowest income level was associated with significantly higher rates of attempts in only young adult women. Among those with the lowest and highest income, the association between ideation and attempts was attenuated, whereas it was enhanced among other income groups.     

Factors Associated with Achieving Complete Mental Health among Individuals with Lifetime Suicidal Ideation

The objective of this study was to identify factors associated with complete mental health among Canadians who had ever seriously considered suicide. Data for this study were obtained from Statistics Canada's 2012 Canadian Community Health Survey–Mental Health (N = 2,844). The outcome variable examined in this study was complete mental health and was analyzed using binary logistic regression. Of the 2,844 respondents with lifetime suicidal ideation, 1,088 (38.2%) had complete mental health (i.e., had flourishing mental health, no mental illness, and no suicidal ideation in the past 12 months). Those who had a confidant were seven times more likely to have complete mental health. Other factors associated with achieving complete mental health among formerly suicidal respondents include being older, being a woman, having higher income, use of religious coping, and never previously having a mental illness. Considering the importance of these protective factors in formulating public health policies will allow for a more wide‐reaching approach to suicide prevention.     

Brooding and reflective rumination among suicide attempters: Cognitive vulnerability to suicidal ideation

Previous research suggests that the brooding subtype of rumination is associated with increased suicidal ideation, but findings are inconsistent with respect to reflection, considered to be the more adaptive form of rumination. This study investigated the circumstances under which reflective rumination might be associated with increased suicidal ideation by examining whether a suicide attempt history moderated the relationship between the ruminative subtypes and current suicidal ideation. Thirty-seven young adults who reported a past suicide attempt and fifty-nine young adults without a suicide attempt history completed measures of rumination and depression symptoms in an initial study session. They then completed a measure of suicidal ideation and hopelessness during a second study session. Overall, brooding was associated with higher self-reported suicidal ideation, whereas reflection was not significantly associated with ideation. However, reflection - but not brooding - interacted with suicide attempt history to statistically predict suicidal ideation, even after adjusting for symptoms of depression and hopelessness, whereas brooding no longer predicted ideation after adjusting for these symptoms. These findings qualify earlier suggestions that reflection is a more adaptive form of rumination by indicating that among vulnerable individuals - in particular those with a history of a suicide attempt - a higher degree of reflective rumination is associated with increased suicidal ideation.
