An Evidence-Based HIV Risk-Reduction Intervention for Young African American Women in the US South Using mHealth: Adaptation and Development Study.

Background: Young African American women have higher rates of sexually transmitted infections, including HIV, than those of young women of other racial and ethnic groups. Gender-, culture-, and age-specific interventions are needed to end the HIV epidemic. The Women's CoOp (WC) is an HIV risk-reduction intervention that is proven to be efficacious in various face-to-face formats.

The Development and Pilot Testing of an Evidence-Based Cardiovascular Disease Risk-Prevention Program to Promote Healthy Lifestyle Behaviors Among African-American College Students - .

Objectives: Cardiovascular disease (CVD) is the leading cause of death in the United States. Among the risk factors for college students, obesity and physical inactivity are disproportionately high among African Americans (AAs), and while studies of the obesity epidemic have increased in recent years, few target AA college-aged students. This study developed and piloted an evidence-based, 15-week, 3-credit hour, CVD risk-prevention and intervention course, that used e-learning, web-based technologies, and a mobile application and compared its effects against a control course.

Use of Mobile Technology Paired with Heart Rate Monitor to Remotely Quantify Behavioral Health Markers among Military Reservists and First Responders.

Introduction: Heart rate variability (HRV) is a biological marker that reflects an individual's autonomic nervous system regulation. Psychological resilience is an individual's ability to recover from an adverse event and return to physiological homeostasis and mental well-being, indicated by higher resting HRV. The Biofeedback Assisted Resilience Training (BART) study evaluates a resilience-building intervention, with or without HRV biofeedback.

Rams Have Heart, a Mobile App Tracking Activity and Fruit and Vegetable Consumption to Support the Cardiovascular Health of College Students: Development and Usability Study.

Background: With the increasing use of mobile devices to access the internet and as the main computing system of apps, there is a growing market for mobile health apps to provide self-care advice. Their effectiveness with regard to diet and fitness tracking, for example, needs to be examined. The majority of American adults fail to meet daily recommendations for healthy behavior.

Mental health, stress, and resilience correlates of heart rate variability among military reservists, guardsmen, and first responders.

The use of heart rate variability (HRV) for monitoring stress has been growing in the behavioral health literature, especially in the areas of posttraumatic stress disorder, stress reactivity, and resilience. Few studies, however, have included general populations under workplace conditions. This study evaluates whether military and other first responders show lower HRV during stress than at baseline and greater post stress rebound, controlling for a myriad of potential confounders.

Adapting Mindfulness Training for Military Service Members With Chronic Pain.

Introduction: Rates of chronic pain in military personnel are disproportionately high. Chronic pain is often associated with mental health and substance use disorders as comorbid conditions, making treatment of chronic pain complex. Mindfulness-based interventions (MBIs) are a promising behavioral approach to managing chronic pain and psychosocial sequelae.

Biofeedback-Assisted Resilience Training for Traumatic and Operational Stress: Preliminary Analysis of a Self-Delivered Digital Health Methodology.

Background: Psychological resilience is critical to minimize the health effects of traumatic events. Trauma may induce a chronic state of hyperarousal, resulting in problems such as anxiety, insomnia, or posttraumatic stress disorder. Mind-body practices, such as relaxation breathing and mindfulness meditation, help to reduce arousal and may reduce the likelihood of such psychological distress.

mHealth versus face-to-face: study protocol for a randomized trial to test a gender-focused intervention for young African American women at risk for HIV in North Carolina.

Background: Disparities in the prevalence of HIV persist in the southern United States, and young African American women have a disproportionate burden of HIV as compared with young women of other racial/ethnic backgrounds. As a result, engaging young African American women in the HIV care continuum through HIV testing is imperative. This study is designed to reach this key population at risk for HIV.

PHIT for Duty, a Mobile Application for Stress Reduction, Sleep Improvement, and Alcohol Moderation.

Post-traumatic stress and other problems often occur after combat, deployment, and other military operations. Because techniques such as mindfulness meditation show efficacy in improving mental health, our team developed a mobile application (app) for individuals in the armed forces with subclinical psychological problems as secondary prevention of more significant disease. Based on the Personal Health Intervention Toolkit (PHIT), a mobile app framework for personalized health intervention studies, PHIT for Duty integrates mindfulness-based relaxation, behavioral education in sleep quality and alcohol use, and psychometric and psychophysiological data capture.

Toward Preventing Post-Traumatic Stress Disorder: Development and Testing of a Pilot Predeployment Stress Inoculation Training Program.

The objective of this pilot study was to design, develop, and evaluate a predeployment stress inoculation training (PRESIT) preventive intervention to enable deploying personnel to cope better with combat-related stressors and mitigate the negative effects of trauma exposure. The PRESIT program consisted of three predeployment training modules: (1) educational materials on combat and operational stress control, (2) coping skills training involving focused and relaxation breathing exercises with biofeedback, and (3) exposure to a video multimedia stressor environment to practice knowledge and skills learned in the first two modules. Heart rate variability assessed the degree to which a subset of participants learned the coping skills.

Relaxation training assisted by heart rate variability biofeedback: Implication for a military predeployment stress inoculation protocol.

Decreased heart rate variability (HRV) is associated with posttraumatic stress disorder (PTSD) and depression symptoms, but PTSD's effects on the autonomic stress response and the potential influence of HRV biofeedback in stress relaxation training on improving PTSD symptoms are not well understood. The objective of this study was to examine the impact of a predeployment stress inoculation training (PRESTINT) protocol on physiologic measures of HRV in a large sample of the military population randomly assigned to experimental HRV biofeedback-assisted relaxation training versus a control condition. PRESTINT altered the parasympathetic regulation of cardiac activity, with experimental subjects exhibiting greater HRV, that is, less arousal, during a posttraining combat simulation designed to heighten arousal.

A Platform to Build Mobile Health Apps: The Personal Health Intervention Toolkit (PHIT).

Personal Health Intervention Toolkit (PHIT) is an advanced cross-platform software framework targeted at personal self-help research on mobile devices. Following the subjective and objective measurement, assessment, and plan methodology for health assessment and intervention recommendations, the PHIT platform lets researchers quickly build mobile health research Android and iOS apps. They can (1) create complex data-collection instruments using a simple extensible markup language (XML) schema; (2) use Bluetooth wireless sensors; (3) create targeted self-help interventions based on collected data via XML-coded logic; (4) facilitate cross-study reuse from the library of existing instruments and interventions such as stress, anxiety, sleep quality, and substance abuse; and (5) monitor longitudinal intervention studies via daily upload to a Web-based dashboard portal.

A personal health information toolkit for health intervention research.

With the emergence of mobile health (mHealth) apps, there is a growing demand for better tools for developing and evaluating mobile health interventions. Recently we developed the Personal Health Intervention Toolkit (PHIT), a software framework which eases app implementation and facilitates scientific evaluation. PHIT integrates self-report and physiological sensor instruments, evidence-based advisor logic, and self-help interventions such as meditation, health education, and cognitive behavior change.

Virtual simulation-enhanced triage training for Iraqi medical personnel.

Triage, establishing the priority of care among casualties in disaster management, is generally practiced using constructive tabletop or live exercises. Actual disasters involving multiple casualties occur rarely, offering little opportunity for gaining experience and competency assessment. When they do occur, response needs to be rapid and well-learned.

Lessons learned in modeling virtual pediatric patients.

In two applications the authors are developing virtual pediatric characters for training and assessment. One application, a virtual pediatric standardized patient, is intended for medical school students rotating through pediatrics to train and assess their basic communications and procedural skills while interacting with kids. The other application presents at-risk teenagers with vignettes to assess risky behavior and impulsivity.
