Randomized Controlled Trial
Training to Improve Spatial Hearing and Situation Awareness when Wearing Hearing Protection.
Hearing protection devices (HPDs) are standard personal protective equipment in military settings, but many service members may choose to not use HPDs because they impair spatial hearing and situation awareness. In an effort to reduce barriers to compliance by improving situation awareness while wearing HPDs, this study investigated whether brief training could counteract spatial hearing deficits when wearing HPDs. Participant's ability to correctly apply the HPDs across days was also examined. ⋯ These findings show that simple, relatively brief practice and training can substantially reduce HPD impairments on spatial hearing and situation awareness. The gains from training and practice can inform the development of relatively simple, brief methods to reduce HPD spatial hearing impairments, potentially leading to increased HPD compliance. Longitudinal data show that a subset of participants would not have received the full benefit of hearing protection because of improper application of the HPDs.

Military service members (SMs) demonstrate high rates of patellofemoral chondral defects (PFCDs) that are difficult to diagnosis and, if untreated, result in a cascade of events eventually leading to osteoarthritis. Running is an essential occupational task for SMs; however, there is little evidence regarding techniques to maintain running ability in individuals with cartilage defects. The purpose of this case series was to assess the clinical application of foot strike run retraining in patients with PFCDs. ⋯ Biomechanical analysis showed that both patients demonstrated a 63% to 70% reduction in average and peak vertical ground reaction force loading rates post-treatment. Modification of foot strike pattern from rear to non-rearfoot strike during running for individuals with PFCD can reduce the magnitude of impact loading, which potentially limits disease progression. These findings suggest that foot strike run retraining may be a feasible strategy to reduce pain and improve function in SMs with PFCD who are required to run for occupational responsibilities.

Randomized Controlled Trial
A Pilot Replication Study of Implementing an Equine-Assisted Services Program Within a VA Residential Substance Use Disorder Treatment Program.
Veterans have high rates of substance use disorders and other mental health conditions including post-traumatic stress disorder. Effective treatments for these conditions exist; however, high attrition rates and residual symptoms after completing treatment are common. Complementary treatment approaches could enhance treatment engagement and/or response among this population. We previously reported a study of one such intervention, an equine-assisted learning, and psychotherapy incorporating horses intervention provided to veterans admitted to a Veterans Health Care Administration residential substance abuse treatment program. The first aim of this study was to replicate the previous study assessing the safety, feasibility, and preliminary outcomes of this intervention. The second aim was to examine the effect of participants attending multiple intervention sessions. ⋯ Taken together, this study and our previous investigation of this equine-assisted services intervention suggest that it is safe and feasible to utilize for veterans admitted to a residential substance abuse treatment program and we have now found short-term benefits in two separate studies. Thus, a randomized controlled trial of this intervention is warranted to demonstrate cause and effect and determine whether longer-term benefits are associated with the intervention. The finding that there was no additional benefit from attendance at more than two intervention sessions suggests that dose-response relationship studies of equine-assisted services interventions for veterans are needed.

The U.S. Army developed a new tool called the Behavioral Health Readiness and Suicide Risk Reduction Review (R4) for suicide prevention. A 12-month evaluation study with the primary objective of testing the hypothesis (H1) that Army units receiving R4 would demonstrate improved outcomes in suicidal-behavior measures following the intervention, relative to control, was then conducted. The results of analyses to answer H1 are herein presented. ⋯ There is no evidence of harm associated with the R4 intervention. R4 effectiveness as a function of R4 itself requires confirmatory study. R4 is judged an improvement (no evidence of harm + weak evidence of effectiveness) over the status quo (no safety data or effectiveness studies) with regard to tool-based decision-making support for suicide prevention in the U.S. Army.

It is important to understand the behavioral and occupational health needs of military police personnel, a high-risk and understudied population. ⋯ It is important to provide tailored resources and programming to employees in high-stress settings to help prevent or manage behavioral and occupational health conditions and reduce the stigma surrounding the utilization of such resources and programs.
