It is critical to develop and implement lab-based computer experiments that simulate real-world tasks in order to characterize operational requirements and challenges or identify potential solutions. Achieving a high degree of laboratory control, operational generalizability, and ease-of-use for a task is challenging, often leading to the development of tasks that can satisfy some facets but not all. This can result in insufficient solutions that leave real-world stakeholders with unsolved problems. ⋯ The lab-based sonar application provides new possibilities for research, not limited to signal intensity and signal density but also through the manipulation of parameters such as the number of unique targets, target appearance, and task duration. This application may illuminate the operational demands that each of these factors may have on operator behavior within the dynamic tasks.

Difficulty controlling anger is a common postdeployment problem in military personnel. Chronic and unregulated anger can lead to inappropriate aggression and is associated with behavioral health, legal, employment, and relationship problems for military service members. Military-related betrayal (e.g., military sexual assault, insider attacks) is experienced by over a quarter of combat service members and is associated with chronic anger and aggression. The high level of physical risk involved in military deployments make interconnectedness and trust in the military organization of utmost importance for survival during missions. While this has many protective functions, it also creates a vulnerability to experiencing military-related betrayal. Betrayal is related to chronic anger and aggression. Individuals with betrayal-related injuries express overgeneralized anger, irritability, blaming others, expectations of injustice, inability to forgive others, and ruminations of revenge. Current approaches to treating anger and aggression in military populations are inadequate. Standard anger treatment is not trauma-informed and does not consider the unique cultural context of anger and aggression in military populations, therefore is not well suited for anger stemming from military-related betrayal. While trauma-informed interventions targeting anger for military personnel exist, anger outcomes are mixed, and aggression and interpersonal functioning outcomes are poor. Also, these anger interventions are designed for patients with posttraumatic stress disorder. However, not all military-related betrayal meets the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition-5 definition of trauma, though it may still lead to chronic anger and aggression. As a result, these patients lack access to treatment that appropriately targets the function of their anger and aggression. ⋯ If outcomes show feasibility, acceptability, and initial effectiveness, CART will demonstrate a culturally relevant treatment for chronic anger, the most frequent postdeployment problem, in a sample of active duty service members who have suffered a military betrayal. The DoD will also have an evidence-based treatment option focusing on interpersonal functioning, including relationships within the military and within families.

Staff nurse attrition negatively impacts readiness of the warfighter and the health and wellbeing of all beneficiaries of the Military Health System (MHS). To promote the retention of a robust nursing workforce, a complete understanding of nurses' perceptions regarding their intent to leave is necessary. The purpose of this study was to explore the free-text responses of 1,438 nurses working among military medical treatment facilities for factors influencing their intent to leave, as an indicator of potential turnover, or attrition. ⋯ Our findings support the evaluation of retention strategies using implementation science for nurses and nurse resource personnel (e.g., nursing assistants, technicians, medics, and corpsman) to ensure a robust nursing work force throughout the MHS. Staff nurses and resource personnel working among military treatment facilities and embedded in units supporting combat and humanitarian missions ensure access to care and health promotion of the warfighter and all MHS beneficiaries.

Rotating shiftwork schedules are known to disrupt sleep in a manner that can negatively impact safety. Consumer sleep technologies (CSTs) may be a useful tool for sleep tracking, but the standard feedback provided by CSTs may not be salient to shift-working populations. SleepTank is an app that uses the total sleep time data scored by a CST to compute a percentage that equates hours of sleep to the fuel in a car and warns the user to sleep when the "tank" is low. Royal Australian Navy aircraft maintenance workers operating on a novel rotational shift schedule were given Fitbit Versa 2s to assess sleep timing, duration, and efficiency across a 10-week period. Half of the participants had access to just the Fitbit app while the other half had access to Fitbit and the SleepTank app. The goal of this study was to evaluate differences in sleep behavior between shifts using an off-the-shelf CST and to investigate the potential of the SleepTank app to increase sleep duration during the 10-week rotational shift work schedule. ⋯ Sleep data collected by Fitbit Versa 2s indicated shorter sleep duration (TIB24, TST24) for Royal Australian Navy workers during early and late shifts relative to stable day shifts. Access to the SleepTank app did not greatly influence measures of sleep duration but may be protective against fatigue by affecting SE. Further research is needed to evaluate the utility of the SleepTank app as a means of improving sleep hygiene in real-world, shift-working environments.

Musculoskeletal injuries (MSIs) pose a significant problem for active duty service members (ADSMs). MSIs may compromise readiness and are one of the main reasons for separation from the Navy and long-term disability. Implementation of optimal treatment strategies rests on understanding the characteristics of MSI complaints in a given population. This study reports on the frequency and nature of MSI complaints of ADSMs seeking care at a military treatment facility (MTF). ⋯ Back and knee injuries were most prevalent in ADSMs reporting an MSI at a Navy shore-based MTF. Shoulder injuries were also common. Of interest, 80% of ADSMs reported at least one MSI comorbidity and 80% reported chronic injury in this study. These rates are higher than those found in a previous study of ADSMs deployed on a carrier. This is notable because chronicity and multiple MSIs are obstacles to readiness. Our findings suggest that ADSMs reporting to shore-based facilities may be at higher risk for disability than their deployed counterparts. This information is important to the development of targeted care to improve readiness in this population.
