Filter by:The objective of this study, named THRIVE (The Research In Virtual Environments Study), is to test hypotheses for how neighborhood environments influence stress and emotion, as a mechanism by which they may influence health. Neighborhood environments may have both acute influences on stress-related processes, but also may have lifespan effects due to the chronic, cumulative effects of repeated exposures and the long-term toll of adapting to adverse neighborhood environments. However, assessing neighborhood influences on stress and emotion is methodologically challenging. This study develops such a novel, alternative approach to address these questions by deploying a virtual reality (VR) based model of neighborhood disadvantage and affluence that creates an immersive experience approximating the experience of being in different neighborhoods. In this study, this model will be applied to understand neighborhood effects in a diverse sample of adolescents (n = 130) from a range of disadvantaged and affluent neighborhoods. The proposed study will employ a randomized experiment (n = 65 per condition), with online questionnaires and a single study session, to determine (a) if virtual exposure to neighborhood disadvantage elicits differences in emotion and stress reactivity; (2) if growing up in a disadvantaged neighborhood results in habituation or sensitization to different neighborhood characteristics; and (3) if chronic stress results in habituation or sensitization to different neighborhood characteristics. This research will develop an innovative methodology that will help establish the role that neighborhoods may play in eliciting stress as well as the processes of adaptation to chronic stress and chronic neighborhood exposures. In addition, it will help establish a method that can be utilized more broadly to study contextual and social environmental influences on psychological and biological risk in adolescence.
High fidelity simulation (HFS) is an established method of training in various fields of medicine, especially emergency medicine, anesthesiology and intensive therapy. One of the benefits of HFS as an educational tool is the protective environment, where the risk of error do not bring harm to the patients. It is proven that HFS is successful in acquisition of new knowledge and skills and may facilitate positive behavioral change in medical students. However, this education method may cause elevated stress levels as well as other physiological reactions. Other than sympathetic nervous system reactions such as heart rate and blood pressure, there are a few laboratory stress level markers such as cortisol, alpha-amylase, testosterone and secretory immunoglobulin A. Our aim was to evaluate the change of stress level induced by high-fidelity simulation in medical students.
The harmful effects of stress on health professionals are expressed both in terms of their health (physical or mental) and the quality of work (reduced memory capacity, deterioration in patient care). These adverse effects highlight the importance of implementing effective coping strategies and/or early learning of stress management methods in medical training programs. Relaxation breathing techniques coupled with heart rate variability (HRV) biofeedback is one of the new techniques used to reduce the stress level. No research has yet tested the effects of HRV induced by relaxation breathing technique before managing a simulated critical situation.
The primary aim of this study is to assess the feasibility of an intervention to reduce and break up prolonged sitting time in full-time police staff. The secondary aims of this study are to assess preliminary effects on patterns of sedentary behaviour (number of breaks, number of prolonged sitting bouts, average duration of prolonged sitting bouts, and total prolonged sitting duration), additional measures of sedentary behaviour (total sitting time, standing, and stepping), cardiometabolic risk markers, physiological stress (cortisol levels), physical health (self-report and postural stability), psychological wellbeing and mood, work stress (self-reported), and work performance (job satisfaction and productivity).
The study will examine changes in acute stress (biological and psychological) via salivary cortisol and alpha amylase levels as well as survey measures of self-reported anxiety in response to either (a) a free online guided mindfulness meditation available at (https://www.uclahealth.org/marc/mindful-meditations); (b) a guided mindfulness meditation via virtual reality (https://guidedmeditationvr.com/) or (c) a virtual reality platform of historic photographs and written narratives (https://lookingglassvr.com/). Participants will also complete an interviewer administered survey to measure sociodemographic factors, mental and physical health status, substance use, and medication use and provide a hair sample to measure cortisol.
This study aims to contribute uniquely to stress, longevity, and mental health research in two ways: by identifying clear protocols of breath-based yoga-meditative practice based on original materials; that are subsequently assessed with established scientific stress, biochemical immunity and longevity markers, and validated psychological measures that relate to mental health.
PROJECT NARRATIVE: As demonstrated by a growing number of studies, experiencing high levels of stress during pregnancy, including elevated levels of the stress hormone cortisol, can lead to significant long-term health problems for mothers and their infants. The objective of the proposed research is to test whether an innovative stress management intervention, offered during pregnancy, is effective in reducing stress and cortisol levels among low-income pregnant women. The results of the proposed work have substantial public health implications in helping to prevent the onset of stress-related health complications among mothers and their infants.
The objective of this project is to examine the clinical effectiveness of a mindfulness intervention on reducing depressive symptoms among socio-economically disadvantaged, racial/ethnic minority adults and explore factors related to implementation in a Federally Qualified Health Center (FQHC). This research will be used to develop a generalizable model for delivery of streamlined mental health interventions in community based settings that will be broadly disseminated and scalable to other populations. Black and Hispanic adults are more likely than those who are White to receive depression treatment in primary care, where antidepressants are the most commonly offered treatment. However, Black and Hispanic adults are less likely than Whites to find antidepressants acceptable. A mindfulness depression intervention provided within primary care may be more accessible and acceptable for low-income, racial/ethnic minority individuals, a severely underserved population. The investigators will conduct a randomized controlled trial to test the clinical effectiveness of a mindfulness intervention (M-Body) on reducing depressive symptoms, compared to usual care, among low-income racial/ethnic minority adults in a FQHC. The M-Body intervention is based on Mindfulness Based Stress Reduction and has been tailored for the FQHC setting and patient population. Adults (N=254) with depressive symptoms will be recruited from a FQHC in the Chicago, IL area that serves majority racial/ethnic minority individuals (90%) living at or below the poverty line (74%). Half of the patients will be randomized to the M-Body intervention arm where they will receive 8-weeks of mindfulness training led by FQHC staff and the other half will be randomized to usual care. Information on factors relevant to implementation of the intervention in the FQHC will be obtained by convening a series of workgroups and individual interviews with FQHC staff, executive leadership and community stakeholders. Specific Aims: 1) Determine the effectiveness of M-Body on reducing depressive symptoms compared to enhanced usual care for racial/ethnic minority adults in a FQHC; 2) Explore potential mediators (stress related biomarkers, mindfulness) and moderators (age, personal, social, environmental stressors) of the intervention's effect; 3) Conduct a broad assessment of organizational and individual agency factors related to preparation and implementation of the M-Body intervention in a FQHC using a mixed methods approach.
Randomised Crossover Trial in Preterm Infants less than 32 weeks to assess Music therapy and sucrose versus sucrose on stress
The goal of this study is to assess the utility of virtual reality technology to aid in the mental health of patients with cardiac disease, specifically looking at decreasing anxiety and perceptions of pain from stressful procedures in the pediatric electrophysiology laboratory.
