Suicide attempts in U.S. Army combat arms, special forces and combat medics

Abstract Background The U.S. Army suicide attempt rate increased sharply during the wars in Iraq and Afghanistan. Risk may vary according to occupation, which significantly influences the stressors that soldiers experience. Methods Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS), we identified person-month records for all active duty Regular Army enlisted soldiers who had a medically documented suicide attempt from 2004 through 2009 (n = 9650) and an equal-probability sample of control person-months (n = 153,528). Logistic regression analyses examined the association of combat occupation (combat arms [CA], special forces [SF], combat medic [CM]) with suicide attempt, adjusting for socio-demographics, service-related characteristics, and prior mental health diagnosis. Results In adjusted models, the odds of attempting suicide were higher in CA (OR = 1.2 [95% CI: 1.1–1.2]) and CM (OR = 1.4 [95% CI: 1.3–1.5]), but lower in SF (OR = 0.3 [95% CI: 0.2–0.5]) compared to all other occupations. CA and CM had higher odds of suicide attempt than other occupations if never deployed (ORs = 1.1–1.5) or previously deployed (ORs = 1.2–1.3), but not when currently deployed. Occupation was associated with suicide attempt in the first ten years of service, but not beyond. In the first year of service, primarily a time of training, CM had higher odds of suicide attempt than both CA (OR = 1.4 [95% CI: 1.2–1.6]) and other occupations (OR = 1.5 [95% CI: 1.3–1.7]). Discrete-time hazard functions revealed that these occupations had distinct patterns of monthly risk during the first year of service. Conclusions Military occupation can inform the understanding suicide attempt risk among soldiers.https://deepblue.lib.umich.edu/bitstream/2027.42/136790/1/12888_2017_Article_1350.pd

Internal consistency and factor structure of a brief scale assessing sensitivity to blood, injury, and mutilation

Abstract Objective US Army soldiers and military veterans experience high rates of post-traumatic stress disorder (PTSD). However, PTSD risk factors are not fully understood. Sensitivity to blood, injury, and mutilation (SBIM), which includes fear of being injured, seeing another person injured, and exposure to mutilation-relevant stimuli (e.g., blood, wounds) may be a PTSD risk factor that is identifiable prior to trauma exposure. Building on previous research that used a subset of items from the Mutilation Questionnaire (MQ), the aim of this study was to examine the reliability and validity of two brief scales assessing SBIM. Results Data from two independent samples of male, US Army soldiers, was utilized to examine a brief 10-item SBIM measure (MQ-SBIM-10) and a shorter version 5-item SBIM measure (MQ-SBIM-5). Internal consistency was indexed by the Kuder–Richardson 20 formula. Construct validity was assessed using confirmatory factor analysis and results obtained from each sample, and from a combined sample. The MQ-SBIM-10 demonstrated acceptable internal consistency and the hypothesized one-factor structure. Although the MQ-SBIM-5 explained a substantial amount of the variance in the 10-item measure and had a one-factor structure, internal consistency of the 5-item measure was poor. Analyses supported the MQ-SBIM-10 as a reliable and cohesive measure of sensitivity to blood, injury, and mutilation

Medically Documented Suicide Ideation Among U.S. Army Soldiers

We used administrative data to examine predictors of medically documented suicide ideation (SI) among Regular Army soldiers from 2006 through 2009 (N = 10,466 ideators, 124,959 control person-months). Enlisted ideators (97.8% of all cases) were more likely than controls to be female, younger, older when entering service, less educated, never or previously deployed, and have a recent mental health diagnosis. Officer ideators were more likely than controls to be female, younger, younger when entering service, never married, and have a recent mental health diagnosis. Risk among enlisted soldiers peaked in the second month of service and declined steadily, whereas risk among officers remained relatively stable over time. Risk of SI is highest among enlisted soldiers early in Army service, females, and those with a recent mental health diagnosis. In recent years, there have been several large-scale efforts to understand the sharp increase in fatal (LeardMann et al., 2013; Reger et al., 2015; Schoenbaum et al., 2014) and nonfatal (Nock et al., 2014; Ursano, Kessler, Heeringa, et al., 2015; Ursano, Kessler, Stein, et al., 2015) suicidal behaviors among U.S. military personnel that occurred during the wars in Iraq and Afghanistan. Suicide ideation (SI) is an important outcome both as an indicator of distress and as a predictor of more serious suicidal behavior (Kessler, Borges, & Walters, 1999; Nock et al., 2014; Ursano, Heeringa, et al., 2015). The lifetime prevalence of SI is approximately 14% among active duty Regular Army soldiers (Nock et al., 2014). The sociodemographic correlates of ideation in service members, including female gender, younger age, and non-Hispanic White race and ethnicity (Nock et al., 2014; Ursano, Kessler, Heeringa, et al., 2015) are consistent with those of the U.S. general population (Borges, Angst, Nock, Ruscio, & Kessler, 2008; Kessler, Berglund, Borges, Nock, & Wang, 2005). Risk of attempting or dying by suicide is higher among enlisted soldiers in their first tour of duty (Gilman et al., 2014; Ursano, Kessler, Stein, et al., 2015), but the relationship of time in service with SI is not yet known. Although the influence of deployment on adverse mental health outcomes is well supported (Bray et al., 2010; Gadermann et al., 2012; Jacobson et al., 2008; Shen, Arkes, & Williams, 2012; Wells et al., 2010), the association of deployment with suicidal thoughts and behaviors has generated inconsistent results (Bryan et al., 2015). Prior mental disorders are a robust predictor of both fatal (Black, Gallaway, Bell, & Ritchie, 2011) and nonfatal (Ursano, Kessler, Stein, et al., 2015) suicidal behaviors in service members, findings in line with a large body of civilian research (Harris & Barraclough, 1997; Nock, Hwang, Sampson, & Kessler, 2010)

Suicide attempts among activated soldiers in the U.S. Army reserve components

Abstract Background Although the majority of active duty U.S. Army soldiers are full-time personnel in the Active Component (AC), a substantial minority of soldiers on active duty are in the Reserve Components (RCs). These “citizen-soldiers” (Army National Guard and Army Reserve) represent a force available for rapid activation in times of national need. RC soldiers experience many of the same stressors as AC soldiers as well as stressors that are unique to their intermittent service. Despite the important role of RC soldiers, the vast majority of military mental health research focuses on AC soldiers. One important goal of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) is to address this gap. Here we examine predictors of suicide attempts among activated RC soldiers. Methods This longitudinal, retrospective cohort study used individual-level person-month records from Army and Department of Defense administrative data systems to examine socio-demographic, service-related, and mental health predictors of medically documented suicide attempts among activated RC soldiers during 2004–2009. Data from all 1103 activated RC suicide attempters and an equal-probability sample of 69,867 control person-months were analyzed using a discrete-time survival framework. Results Enlisted soldiers comprised 84.3% of activated RC soldiers and accounted for 95.7% of all activated RC suicide attempts (overall rate = 108/100,000 person-years, more than four times the rate among officers). Multivariable predictors of enlisted RC suicide attempts included being female, entering Army service at age ≥ 25, current age < 30, non-Hispanic white, less than high school education, currently married, having 1–2 years of service, being previously deployed (vs. currently deployed), and history of mental health diagnosis (particularly when documented in the previous month). Predictors among RC officers (overall rate = 26/100,000 person-years) included being female and receiving a mental health diagnosis in the previous month. Discrete-time hazard models showed suicide attempt risk among enlisted soldiers was inversely associated with time in service. Conclusions Risk factors for suicide attempt in the RCs were similar to those previously observed in the AC, highlighting the importance of research and prevention focused on RC enlisted soldiers in the early phases of Army service and those with a recent mental health diagnosis

Suicide attempts in U.S. Army combat arms, special forces and combat medics

Background: The U.S. Army suicide attempt rate increased sharply during the wars in Iraq and Afghanistan.

Discrete-time hazard functions revealed that these occupations had distinct patterns of monthly risk during the first year of service. Conclusions: Military occupation can inform the understanding suicide attempt risk among soldiers.
