Understanding Motivational Factors of Problematic Video Gaming in the USMC and the US Navy

NPS NRP Executive SummaryA significant percentage of active duty service members (ADSMs) spends free time playing video games. This recreational activity is not unexpected given the relatively young age of many ADSMs and the prevalence of video gaming in the US population. The military operational environment, however, is characterized by high levels of occupational stress and poor sleep conditions which can result in increased risk of depression, anxiety, and sleep disorders. In such conditions, video games may be a strategy for coping with stress. In contrast, excessive video gaming can become problematic because it has the potential to affect well-being and behavior. For example, excessive video gaming is associated with high stress levels (Milani et al., 2018), lower psychosocial well-being and psychological functioning (von der Heiden et al., 2019), loneliness and depression (Lemmens et al., 2011), and delinquency and aggressive behavior (Milani et al., 2018; Engelhardt et al., 2011; Ewoldsen et al., 2012). Video gaming may also interfere with sleep when gamers stay up late playing video games instead of sleeping (Matsangas, Shattuck, & Saitzyk, 2020). In extreme cases, video gaming can become an addiction. In the scientific literature, Internet Gaming Disorder (IGD) is associated with poor emotion regulation, impaired prefrontal cortex functioning and cognitive control, poor working memory and decision-making capabilities, and a neuronal deficiency similar to substance-related addictions (Kuss et al., 2018). Given its potential negative impact on individual and team performance, we propose to assess problematic video gaming in two samples: US Marine Corps personnel and US Navy sailors. Based on surveys and focus groups, the research approach will be tailored for the needs of each service. Data will be collected from personnel in up to three USMC commands, whereas data from USN sailors will be collected on two ships, one in port and one underway. The study will focus on assessing the prevalence and extent of playing video games, identify factors associated with this activity, address whether Marines and Sailors are using gaming as a maladaptive coping mechanism, and provide appropriate recommendations.HQMC Manpower and Reserve Affairs (M&RA)This research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

OFRP Phase Variation in Signature and Destructive Behaviors

NPS NRP Executive SummaryThis study will investigate the destructive behavior surge during the maintenance phase of the Optimized Fleet Response Plan (OFRP). The Culture of Excellence Campaign's Perform to Plan effort will empower warfighting capability by fostering psychological, physical and emotional toughness. To meet this goal, the Navy needs to understand what encourages signature behaviors and reduces destructive behaviors and how these behaviors impact readiness. This study will provide critical insight to encourage signature behaviors and counter destructive behaviors. Researchers will use a mixed-methods, explanatory sequential design to answer the questions: What are the rates of signature and destructive behaviors during phases of OFRP? Do rates differ by command type? How do signature and destructive behaviors impact readiness?N1 - Manpower, Personnel, Training & EducationThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

Efficacy of Medical Operations and Layout Planning Onboard Nontraditional US Navy Vessels at High Seas

The article of record as published may be found at http://dx.doi.org/10.1093/milmed/usz227Introduction: Attempting to expedite delivery of care to wounded war fighters, this study aimed to quantify the ability of medical and surgical teams to perform lifesaving damage control and resuscitation procedures aboard nontraditional US Navy Vessels on high seas. Specifically, it looked at the ability of the teams to perform procedures in shipboard operating and emergency rooms by analyzing motion of personnel during the procedures. Methods: One hundred and twelve damage control and resuscitation procedures were performed during a voyage of the US Naval Ship Brunswick in transit from Norfolk, Virginia, to San Diego, California. The ability of personnel to perform these procedures was quantified by the use of motion link analysis designed to track the movement of each participant as they completed their assigned tasks. Results: The link analysis showed no significant change in the number of movements of participants from the beginning to the end of the study. However, there was a learning effect observed during the study, with teams completing tasks faster at the end of the study than at the beginning. Conclusion: This shows that the working conditions aboard the US Naval Ship Brunswick were satisfactory for the assigned tasks, indicating that these medical operations may be feasible aboard nontraditional US Navy vessels.This specific study was a part of a major three-phase investigation entitled �Effect of High Deck Accelerations on Surgical Tasks� funded by the following organizations for each phase: Phase I�Office of Naval Research, Phase II�Office of the Chief of Naval Operations (OPNAV) N81, and Phase III�Advanced Medical Development and OPNAV N81.This specific study was a part of a major three-phase investigation entitled �Effect of High Deck Accelerations on Surgical Tasks� funded by the following organizations for each phase: Phase I�Office of Naval Research, Phase II�Office of the Chief of Naval Operations (OPNAV) N81, and Phase III�Advanced Medical Development and OPNAV N81

Rise and shine: The use of polychromatic short-wavelength-enriched light to mitigate sleep inertia at night following awakening from slow-wave sleep

Sleep inertia is the brief period of performance impairment and reduced alertness experienced after waking, especially from slow-wave sleep. We assessed the efficacy of polychromatic short-wavelength-enriched light to improve vigilant attention, alertness and mood immediately after waking from slow-wave sleep at night. Twelve participants (six female, 23.3 ± 4.2 years) maintained an actigraphy-confirmed sleep schedule of 8.5 hr for 5 nights, and 5 hr for 1 night prior to an overnight laboratory visit. In the laboratory, participants were awakened from slow-wave sleep, and immediately exposed to either dim, red ambient light (control) or polychromatic short-wavelength-enriched light (light) for 1 hr in a randomized crossover design. They completed a 5-min Psychomotor Vigilance Task, the Karolinska Sleepiness Scale, and Visual Analogue Scales of mood at 2, 17, 32 and 47 min after waking. Following this testing period, lights were turned off and participants returned to sleep. They were awakened from their subsequent slow-wave sleep period and received the opposite condition. Compared with the control condition, participants exposed to light had fewer Psychomotor Vigilance Task lapses (χ2[1] = 5.285, p = 0.022), reported feeling more alert (Karolinska Sleepiness Scale: F1,77 = 4.955, p = 0.029; Visual Analogue Scalealert: F1,77 = 8.226, p = 0.005), and reported improved mood (Visual Analogue Scalecheerful: F1,77 = 8.615, p = 0.004). There was no significant difference in sleep-onset latency between conditions following the testing period (t10 = 1.024, p = 0.330). Our results suggest that exposure to polychromatic short-wavelength-enriched light immediately after waking from slow-wave sleep at night may help improve vigilant attention, subjective alertness, and mood. Future studies should explore the potential mechanisms of this countermeasure and its efficacy in real-world environments

Physiological and Cognitive Performance in F-22 Pilots During Day and Night Flying

The article of record as published may be found at https://doi.org/10.3357/AMHP.5508.2021Many workers routinely transition between day and night shifts—including pilots, where night flights are commonly considered more stressful. The physiological toll from this transition is not fully understood, though fatigue is a factor in many aviation accidents. This research investigated the changes in physiological markers of stress and cognitive performance as F-22 pilots transitioned from day flying to night flying

Leaning in to Address Sleep Disturbances and Sleep Disorders in Department of Defense and Defense Health Agency

Letter to the Editor, Military Medicine, 187, 5/6:155, 202217 USC 105 interim-entered record; under review.The article of record as published may be found at http://dx.doi.org/10.1177/0018720820906050In their article entitled, “Engaging Stakeholders to Optimize Sleep Disorders Management in the U.S. Military: A Qualitative Analysis,” Abdelwadoud and colleagues conducted focus groups of service members, primary care managers (PCMs), and administrative stakeholders about their perceptions, experiences, roles in sleep management, stated education needs, and management of sleep disorders.1 The qualitative methods are rigorous, and the findings reinforce and nuance prior results, especially regarding key requirements from PCMs. We feel compelled, however, to further nuance the authors’ conclusion that “current military sleep management practices are neither satisfactory nor maximally effective” and offer specific examples of actions taken by the Department of Defense (DoD) and Defense Health Agency (DHA) in recognition of the significance of optimal sleep in combat readiness and overall health of service members. We offer here a succinct list of concrete efforts to support and implement substantial clinical, operational, research, or educational efforts by the DoD or DHA to improve sleep in service members and associated clinical challenges in this unique population.Identified in text as U.S. Government work

Assessing Surgical Task Load and Performance: A Comparison of Simulation and Maritime Operation

The article of record as published may be found at http://dx.doi.org/10.1093/milmed/usz297This study examined the effects of simulated and actual vessel motion at high seas on task load and surgical performance. Methods: This project was performed in phases. Phase I was a feasibility study. Phase II utilized a motion base simulator to replicate vessel motion. Phase III was conducted aboard the U.S. Naval Ship Brunswick. After performing surgical tasks on a surgical simulation mannequin, participants completed the Surgical Task Load Index (TLX) designed to collect workload data. Simulated surgeries were evaluated by subject matter experts. Results: TLX scores were higher in Phase III than Phase II, particularly at higher sea states. Surgical performance was not significantly different between Phase II (84%) and Phase III (89%). Simulated motions were comparable in both phases. Conclusions: Simulated motion was not associated with a significant difference in surgical performance or deck motion, suggesting that this simulator replicates the conditions experienced during surgery at sea on the U.S. Naval Ship Brunswick. However, Surgical TLX scores were dramatically different between the two phases, suggesting increased workload at sea, which may be the result of time at sea, the stress of travel, or other factors. Surgical performance was not affected by sea state in either phase.Bureau of Medicine USN; OPNAV N-81 Assessments Division, Medical Analysis Branch; Navy Advanced Medical Development; Naval Surface Warfare Center, PC.Phase I of this study was sponsored by the Office of Naval Research.

Guiding principles for determining work shift duration and addressing the effects of work shift duration on performance, safety, and health

The article of record as published may be found at http://dx.doi.org/10.1093/sleep/zsab161Risks associated with fatigue that accumulates during work shifts have historically been managed through working time arrangements that specify fixed maximum durations of work shifts and minimum durations of time off. By themselves, such arrangements are not sufficient to curb risks to performance, safety, and health caused by misalignment between work schedules and the biological regulation of waking alertness and sleep. Science-based approaches for determining shift duration and mitigating associated risks, while addressing operational needs, require: 1) a recognition of the factors contributing to fatigue and fatigue-related risks; 2) an understanding of evidence-based countermeasures that may reduce fatigue and/or fatigue-related risks; and 3) an informed approach to selecting workplace-specific strategies for managing work hours. We propose a series of guiding principles to assist stakeholders with designing a shift duration decision-making process that effectively balances the need to meet operational demands with the need to manage fatigue-related risks.Academy of Sleep Medicine (AASM)Sleep Research Societ

Reconfigurations in brain networks upon awakening from slow wave sleep: Interventions and implications in neural communication

AbstractSleep inertia is the brief period of impaired alertness and performance experienced immediately after waking. Little is known about the neural mechanisms underlying this phenomenon. A better understanding of the neural processes during sleep inertia may offer insight into the awakening process. We observed brain activity every 15 min for 1 hr following abrupt awakening from slow wave sleep during the biological night. Using 32-channel electroencephalography, a network science approach, and a within-subject design, we evaluated power, clustering coefficient, and path length across frequency bands under both a control and a polychromatic short-wavelength-enriched light intervention condition. We found that under control conditions, the awakening brain is typified by an immediate reduction in global theta, alpha, and beta power. Simultaneously, we observed a decrease in the clustering coefficient and an increase in path length within the delta band. Exposure to light immediately after awakening ameliorated changes in clustering. Our results suggest that long-range network communication within the brain is crucial to the awakening process and that the brain may prioritize these long-range connections during this transitional state. Our study highlights a novel neurophysiological signature of the awakening brain and provides a potential mechanism by which light improves performance after waking
