Trends in mental health outcomes and combat exposure among US marines returning from Iraq, Afghanistan or other deployments, 2004-13.

BACKGROUND: As of 2015, more than 2.7 million US military Veterans have served in support of the Global War on Terror. The negative sequelae associated with deployment stressors and related traumas are well-documented. Although data on mental health issues are routinely collected from service members returning from deployment, these data have not been made publicly available, leaving researchers and clinicians to rely on convenience samples, outdated studies and small sample sizes. METHODS: Population-based data of US Marines returning from deployment between 2004 and 2013 were analyzed, using the Post-Deployment Health Assessment. RESULTS: Rates of Marines returning from Iraq who screened positive for depression ranged from 19.31 to 30.02%; suicidal ideation ranged from 0 to 1.44%. Marines screening positive for PTSD ranged from 3.00 to 12.41%; combat exposure ranged from 15.58 to 55.12%. Depression was indicated for between 12.54 and 30.04% of Marines returning from Afghanistan, while suicidal ideation ranged from 0 to 5.33%. PTSD percentages ranged from 6.64 to 18.18%; combat exposure ranged between 42.92 and 75%. CONCLUSION: Our results support the heterogeneity of experiences and mental health sequelae of service members returning from deployments. Outcomes for Afghanistan and Iraq Veterans fluctuate with changes in OPTEMPO across theaters over time.

Performance and clinical utility of a short violence risk screening tool in U.S. adults with mental illness.

Risk assessment instruments are typically long, costly, and resource-intensive. Thus, a short, easily administered preliminary screening tool can increase the efficiency of the subsequent violence risk assessment process. A preliminary tool can identify those at low risk of violence so that they can be screened out of the process of further violence risk assessment. Recently, Singh, Grann, Lichtenstein, Långström, and Fazel (2012) used data drawn from national registries to develop a short screening tool for a sample of Swedish adults diagnosed with schizophrenia. The screening tool included 5 items: male sex, previous criminal conviction, under 32 years of age, alcohol abuse, and drug abuse. The current study examines the predictive validity and clinical utility of the screening tool developed by Singh et al. (2012) in predicting community-based violence over 6-month and 12-month durations in U.S. adults with schizophrenia (n = 3,471) and the generalizability of those findings to the assessment of violence risk in adults with other primary diagnoses. Results demonstrated that the screening tool performed reasonably well at screening out individuals who did not commit violence during follow-up; however, the screening tool did not perform as well at identifying individuals who did commit violence during follow-up. Although those who screened positive were about twice as likely to engage in violence in the 6-month follow-up period, by the 12-month follow-up there was little difference in likelihood of engaging in violence between participants who were screened in and those who were screened out. Overall, findings of the present study do not provide compelling support for the clinical utility of the screening tool in its current form.

Predictors of Posttraumatic Stress Disorder, Anxiety Disorders, Depressive Disorders, and Any Mental Health Condition Among U.S. Soldiers and Marines, 2001-2011.

Understanding mental health disorder diagnosis and treatment seeking among active-duty military personnel is a topic with both clinical and policy implications. It has been well documented in military populations that individual-level military experience, including deployment history and combat exposure, influences mental health outcomes, but the impact of unit-level factors is less well understood. In the current study, we used administrative longitudinal data to examine a comprehensive set of unit- and individual-level predictors of posttraumatic stress disorder (PTSD), non-PTSD anxiety disorders, depressive disorders, and overall mental health diagnoses among Army and Marines Corps personnel. Using Cox survival models for time-dependent variables, we analyzed time from military accession (between January 1, 2001 and December 31, 2011) until first mental health diagnosis for 773,359 soldiers and 332,093 Marines. Prior diagnosis of a substance abuse disorder during one's military career, hazard ratios (HRs) = 1.68-3.10, and cumulative time spent deployed, HRs = 1.11-2.04, were the most predictive risk factors for all outcomes. Male sex, HRs = 0.35-0.57, and officer rank, HRs = 0.13-0.23, were the most protective factors. Unit-level rate of high deployment stress was a small but significant predictor of all outcomes after controlling for individual-level deployment history and other predictors, HRs = 1.01-1.05. Findings suggest both unit- and individual-level risk and protective factors of mental health diagnoses associated with treatment seeking. Clinical, including mental health assessment and management, and policy implications related to the military environment and the individual as it relates to mental health disorders are discussed.

Predictive validity of HCR-20, START, and static-99R assessments in predicting institutional aggression among sexual offenders.

Sexual offenders are at greater risk of nonsexual than sexual violence. Yet, only a handful of studies have examined the validity of risk assessments in predicting general, nonsexual violence in this population. This study examined the predictive validity of assessments completed using the Historical-Clinical-Risk Managment-20 Version 2 (HCR-20; Webster, Douglas, Eaves, & Hart, 1997), Short-Term Assessment of Risk and Treatability (START; Webster, Martin, Brink, Nicholls, & Desmarais, 2009), and Static-99R (Hanson & Thornton, 1999) in predicting institutional (nonsexual) aggression among 152 sexual offenders in a large secure forensic state hospital. Aggression data were gathered from institutional records over 90-day and 180-day follow-up periods. Results support the predictive validity of HCR-20 and START, and to a lesser extent, Static-99R assessments in predicting institutional aggression among patients detained or civilly committed pursuant to the sexually violent predator (SVP) law. In general, HCR-20 and START assessments demonstrated greater predictive validity-specifically, the HCR-20 Clinical subscale scores and START Vulnerability total scores-than Static-99R assessments across types of aggression and follow-up periods.
