Filter by:The purpose of this study is to strengthen school achievement and positive mental health, and to prevent and reduce school dropout and mental distress among high school students. The researchers will scale up techniques that have already been proven highly effective in preventing common mental disorders (depression, anxiety) in high risk groups (indicated and selective prevention). The researchers will disseminate these techniques to entire first year classes of high school students irrespective of risk factors (universal prevention). The study will report whether universal delivery in school of "Mind Power" - a Cognitive Behaviour Therapy (CBT) based programme - will strengthen school grades, self-efficacy, self-esteem, self-regulation, mental perceptions and well-being, and prevent and reduce school dropout, and symptoms of anxiety and depression. In addition the researchers will analyse whether such universal delivery prevents more mental distress, and is more cost-effective than when it is delivered only to those at high risk for school failure, dropout, or mental distress.
The goal of this randomized supplementation feasibility trial is to learn about the feasibility and preliminary efficacy of the probiotic, lactobacillus plantarum 299v (Lp299v), in pregnant individuals at-risk for iron deficiency anemia. The main questions it aims to answer are: - Is daily oral Lp299v a feasible and tolerable intervention for pregnant individuals to uptake? - Does daily oral Lp299v in pregnancy impact maternal and neonatal cord hematological and iron status parameters? Participants will be randomly assigned to one of two treatment groups: daily intake or probiotic Lp299v + prenatal vitamin with iron or placebo + prenatal vitamin with iron from 15-20 weeks of gestation through delivery. Researchers will compare the two treatment groups to see if there is a difference in the feasibility of the intervention and the preliminary efficacy on maternal and neonatal cord hematological and iron status parameters.
The purpose of this study is to examine the effects of a developed psychosocial eHealth intervention on the proposed primary outcomes, health-related quality of life and symptom burden, among Hispanic breast cancer survivors. The intervention components include breast cancer knowledge, stress awareness and management, social support, and enhanced communication and intimacy skills. The intervention will be delivered via a Smartphone application over an 8-week period. Participants are randomized into either an intervention application (described above) or a control application (health information and health promotion strategies). Aside from using the Smartphone application for the recommended 8 weeks, participation in this study includes three assessments: baseline (at the beginning of the research study), 6-week follow-up, and 8-week follow-up.
In this study, it will be investigated how psychological stress evoked by skydiving affects the intestinal permeability in 20 healthy subjects. Participants attend two visits: 1) Skydiving visit, 2) Negative control visit. At all visits, saliva samples, blood samples, and faecal samples are collected, and the multi-sugar permeability test is performed. In this test, participants drink a sugar solution and then collect urine for 5 and 24 h. The ratio of the sugars detected in the urine is a reflection of the intestinal permeability. Saliva samples are collected for assessment of cortisol, a stress marker. Blood and faecal samples are collected for assessment of markers of intestinal barrier function and inflammation.
Early life stress (ELS) is associated with a number of psychiatric and medical conditions later in life, thought to be caused by subsequent disruptions in biological processes involved in regulation of stress responses. Given that these alterations have long-lasting effects, there is a great need for effective preventative interventions. The long-term goal of this project is to identify early interventions that may most powerfully mitigate risk for psychiatric illness among adolescents with exposure to early life stress (ELS), with a focus on interventions that can be widely and effectively implemented, have the potential for long-lasting benefits, and can effectively engage targeted neurobiological processes and networks. The specific aims of the present study are to 1) examine how ELS impacts biological processes associated with regulation of stress, and 2) identify how MBI impacts affective symptoms and biological processes dysregulated by ELS. This study supports the efforts to reduce the effects of early adversity in children by testing an impact of an effective psychological intervention on disrupted biological processes caused by early adversity. Successful achievement of the proposed aims will contribute to a) the knowledge base needed to reduce the effects of trauma and stress in children and families and b) the development of easily implemented and disseminated preventative interventions. The proposed study will utilize a multi-method design to examine the effect of mindfulness on biological processes (i.e., stress responses) disrupted by exposure to ELS among adolescents age 13 to 15. Adolescents will first complete self-report measures of childhood adverse experiences, trauma, and neglect. Forty eligible adolescents will be next randomly assigned to either an eight session mindfulness-based stress reduction intervention for teens or no treatment. Pre- and post-intervention assessment will include (a) self-report measures of symptoms and emotion regulation, (b) a blood draw for assessment of inflammatory markers and gene expression, and (c) a stress task with saliva cortisol collected before and after this task.
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.
The aim of this study is to determine if and how the "Probiotic Product" affects functional brain responses in healthy subjects during an emotional- and arithmetic stress task, respectively and in terms of microbe-brain-gut interactions.
This pilot study aims to find the most effective relaxation technique to help primiparous mothers who are breastfeeding their infant. The effect of five different relaxation techniques on physical and psychological changes in Chinese mothers will be investigated. The interventions to be used in this study include: guided relaxation meditation tape, music tape, relaxation lighting, combined relaxation meditation and lighting, and combined music and lighting.
Mothers who were enrolled in the Mood, Mother and Infant study will be eligible to participate in the 6-year follow-up maternal visit. At the time of this visit, mothers will be randomized to a single 24 IU dose of nasal oxytocin or placebo. Following administration of the study drug, women will participate in the Trier Social Stress Test (TSST), and blood samples will be collected to quantify HPA axis reactivity.
While the stress response, characterised by an increase in heart rate, blood pressure, and cortisol, has evolved to ensure the survival of the organism in face of danger, chronic stress due to psychological stressors can be harmful. The opposite of the stress response is the "relaxation response". Mind-body techniques such as meditation, guided imagery and music therapy are thought to induce this response. The relaxation response is characterized as a wakeful hypometabolic state, where a decrease in central nervous system arousal is observed. Some studies reported a reduction in stress hormones, and in symptoms of anxiety and depression following the use of mind-body relaxation techniques. Other studies noted a reduction in stress measured using physiological measurements such as heart rate and blood pressure. Light therapy is another technique that is suggested to induce physiological changes similar to those seen in the relaxation response. Some studies have shown a reduction in heart rate, blood pressure, oxygen consumption and carbon dioxide production following exposure to blue light. These relaxation therapies can be useful for the general population and for vulnerable groups where alternative therapies, such as medication and psychotherapy, are difficult. Limited amount of studies have quantified the decrease in stress in physiological measurements such as heart rate and blood pressure. The aim of this study is to investigate which relaxation technique among five different interventions (and one control) is the most effective in improving relaxation and reducing stress in adult women of reproductive age (18-45 years). The results of this study will be used to inform the intervention of a study testing the impact of relaxation therapy on breastfeeding outcomes in mothers of late preterm infants.
