Combat and operational stress programs and interventions: A scoping review using a tiered prevention framework.

Beginning in 1999, Department of Defense policy directed the military services to develop Combat and Operational Stress Control (COSC) programs to address prevention, early identification, and management of the negative effects of combat and operational stress. The aim of this study is to provide a narrative review of COSC programs and organize them into a prevention framework to clarify gaps and future directions. A systematic search was conducted to identify studies between 2001 and 2020 in peer-reviewed articles or government-sponsored reports describing an evaluation of COSC programs. The target population of these programs was US service members who had participated in an intervention designed to address combat or operational stress in a deployed, operational, or field setting. These programs then were rated for level of evidence and categorized using a tiered prevention model. This search identified 36 published evaluations of 19 COSC programs and interventions from. Most programs were described as effective in addressing target outcomes, with behavioral health outcomes reported for 13 of the 19 identified programs; the remaining six focused on knowledge base and behavior changes. Delivery of these prevention programs also ranged from peer-based implementation to formal treatment, including programs at all prevention levels. COSC interventions show promise for helping service members manage stress, with more than half of the programs showing evidence from studies using randomized designs. Future iterations of COSC program evaluations should explore the development of a joint curriculum using existing content in a tiered prevention framework.

Resilience to Suicidal Ideation Among U.S. Military Veterans with Posttraumatic Stress: Results from the National Health and Resilience in Veterans Study.

Veterans with combat exposure experience high rates of posttraumatic stress symptoms (PTSS) and associated suicidal ideation. The current study examined whether social support (i.e., social connectedness and social engagement) and protective psychological factors (i.e., resilience and altruism) moderated the relation between PTSS and suicidal ideation severity in a sample of 149 U.S. military combat veterans who served in the Vietnam War or Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND). Consistent with expectations, initial PTSS were positively associated with concurrent and three-year follow-up severity of suicidal ideation. Moderation analyses revealed the relation between initial PTSS and concurrent suicidal ideation severity was no longer significant at above average levels of social connectedness, social engagement, and psychological resilience. Further, the relation between initial PTSS and suicidal ideation severity three years later continued to be buffered by above average levels of social engagement. Results suggest social connectedness, psychological resilience, and social engagement help moderate initial severe thoughts of suicide linked to PTSS, while social engagement might be the strongest protective factor against severe suicidal ideation over time. Empirically-supported prevention and treatment efforts enhancing social engagement may help promote resilience to severe PTSS-related suicidal ideation among veterans from Vietnam and OEF/OIF/OND combat eras.

Intermittent explosive disorder: associations with PTSD and other Axis I disorders in a US military veteran sample.

This study examined the prevalence of intermittent explosive disorder (IED) and its associations with trauma exposure, posttraumatic stress disorder (PTSD), and other psychiatric diagnoses in a sample of trauma-exposed veterans (n=232) with a high prevalence of PTSD. Structural associations between IED and latent dimensions of internalizing and externalizing psychopathology were also modeled to examine the location of IED within this influential structure. Twenty-four percent of the sample met criteria for a lifetime IED diagnosis and those with the diagnosis were more likely to meet criteria for lifetime PTSD than those without (30.3% vs. 14.3% respectively). Furthermore, regression analyses revealed lifetime PTSD severity to be a significant predictor of IED severity after controlling for combat, trauma exposure, and age. Finally, confirmatory factor analysis revealed significant cross-loadings of IED on both the externalizing and distress dimensions of psychopathology, suggesting that the association between IED and other psychiatric disorders may reflect underlying tendencies toward impulsivity and aggression and generalized distress and negative emotionality, respectively.

Alcohol and drug abuse among U.S. veterans: comparing associations with intimate partner substance abuse and veteran psychopathology.

This study examined the relative influences of posttraumatic stress disorder (PTSD), other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.
