Neurocognitive Function and Suicide in U.S. Army Soldiers.

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004-2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal-probability sample of 9,893 person-months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [ß] = -.197 to -.521; p < .01) and MTH (ß = -.024 to -.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (ß = -.164 to -.417; p < .05) and MTH continued to be associated with suicide attempt (ß = -.015; p = .046) and ideation (ß = -.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk.

Risk Factors, Methods, and Timing of Suicide Attempts Among US Army Soldiers.

IMPORTANCE: Suicide attempts in the US Army have risen in the past decade. Understanding the association between suicide attempts and deployment, as well as method and timing of suicide attempts, can assist in developing interventions. OBJECTIVE: To examine suicide attempt risk factors, methods, and timing among soldiers currently deployed, previously deployed, and never deployed at the time this study was conducted. DESIGN, SETTING, AND PARTICIPANTS: This longitudinal, retrospective cohort study of Regular Army-enlisted soldiers on active duty from 2004 through 2009 used individual-level person-month records to examine risk factors (sociodemographic, service related, and mental health), method, and time of suicide attempt by deployment status (never, currently, and previously deployed). Administrative data for the month before each of 9650 incident suicide attempts and an equal-probability sample of 153 528 control person-months for other soldiers were analyzed using a discrete-time survival framework. MAIN OUTCOMES AND MEASURES: Suicide attempts and career, mental health, and demographic predictors were obtained from administrative and medical records. RESULTS: Of the 9650 enlisted soldiers who attempted suicide, 86.3% were male, 68.4% were younger than 30 years, 59.8% were non-Hispanic white, 76.5% were high school educated, and 54.7% were currently married. The 40.4% of enlisted soldiers who had never been deployed (n = 12 421 294 person-months) accounted for 61.1% of enlisted soldiers who attempted suicide (n = 5894 cases). Risk among those never deployed was highest in the second month of service (103 per 100 000 person-months). Risk among soldiers on their first deployment was highest in the sixth month of deployment (25 per 100 000 person-months). For those previously deployed, risk was highest at 5 months after return (40 per 100 000 person-months). Currently and previously deployed soldiers were more likely to attempt suicide with a firearm than those never deployed (currently deployed: OR, 4.0; 95% CI, 2.9-5.6; previously deployed: OR, 2.7; 95% CI, 1.8-3.9). Across deployment status, suicide attempts were more likely among soldiers who were women (currently deployed: OR, 3.4; 95% CI, 3.0-4.0; previously deployed: OR, 1.5; 95% CI, 1.4-1.7; and never deployed: OR, 2.4; 95% CI, 2.3-2.6), in their first 2 years of service (currently deployed: OR, 1.9; 95% CI, 1.5-2.3; previously deployed: OR, 2.2; 95% CI, 1.9-2.7; and never deployed: OR, 3.1; 95% CI, 2.7-3.6), and had a recently received a mental health diagnosis in the previous month (currently deployed: OR, 29.8; 95% CI, 25.0-35.5; previously deployed: OR, 22.2; 95% CI, 20.1-24.4; and never deployed: OR, 15.0; 95% CI, 14.2-16.0). Among soldiers with 1 previous deployment, odds of a suicide attempt were higher for those who screened positive for depression or posttraumatic stress disorder after return from deployment and particularly at follow-up screening, about 4 to 6 months after deployment (depression: OR, 1.4; 95% CI, 1.1-1.9; posttraumatic stress disorder: OR, 2.4; 95% CI, 2.1-2.8). CONCLUSIONS AND RELEVANCE: Identifying the timing and risk factors for suicide attempt in soldiers requires consideration of environmental context, individual characteristics, and mental health. These factors can inform prevention efforts.

Types, Subtypes, and Severity of Substantiated Child Neglect in U.S. Army Communities.

BACKGROUND: Neglect has been linked to short-term and long-term deleterious outcomes in children, but has received little attention in the research literature. OBJECTIVE: Identify types, subtypes, and severity of child neglect in a sample of substantiated cases at 4 U.S. Army installations. Describe demographic correlates of victims and offenders by type and subtype. PARTICIPANTS: Data were collected from archived clinical records. A stratified random sample of 100 substantiated child neglect case files were selected per site (N = 400). Data from a single child per case file were used. RESULTS: 5 types and 17 subtypes of neglect were represented, singly or in combination, with varying severity. Lack of Supervision was most common (n = 177, 35.3%), followed by Emotional Neglect (n = 159, 31.8%), Failure to Provide Physical Needs (n = 131, 26.2%), Moral-Legal Neglect (n = 20, 4%), and Educational Neglect (n = 13; 2.6%). Child neglect occurred mostly among young children and in young enlisted families. CONCLUSIONS: Current results highlight the need to focus on types, subtypes, and severity of neglect incidents that provide specific understanding of child risk to better inform policy. Further study should examine specific risk factors and their relationship to neglect types and severity outcomes.
