Filter by:Theory and research on the gut-brain-axis emphasize complex interactions between the gut microbiota, immunological and hormonal responses, brain function, brain structure, as well as resulting behavioral manifestations, such as cognitive functions and mental illness. Probiotics are living micro-organisms that change the composition of the gut microbiota and hypothetically have a positive effect on the host's general health and well-being. Probiotic bacteria naturally occur in foods such as Sauerkraut, olives, and dark chocolate, and are currently also added to industrial products such as yogurt. Regarding the effect of probiotics on brain structure and function, animal studies have shown that the administration of probiotics in mice and rats was linked to neurogenesis in the hippocampus and an improvement of associated cognitive functions. The majority of these studies applied probiotics for 4 weeks. The substances used in these studies were often composed of several bacterial strains, suggesting that the neurogenic effect may not be reducible to a specific type of probiotic bacteria. Probiotics seem to be effective in improving memory abilities, including spatial and non-spatial memory, both in rodents and humans. Moreover, specifically regarding the beneficial effect of probiotics on anxiety, depression and stress, preliminary evidence in humans is compelling. However methodologically sound (randomized-controlled trial [RCT], 'blind') studies are still lacking. To sum up, the present study is going to be the first RCT with human participants that investigates structural and functional changes of the hippocampus through probiotic bacteria, using Magnet Resonance Imaging (MRI). In addition, the study aims at advancing research in the field by investigating the effects of probiotics on a broad spectrum of cognitive functions, particularly those associated with hippocampal activity (e.g. spatial memory, verbal memory). Furthermore, effects on several types of mental illness (e.g. anxiety, depression, stress) will be studied. Potential translatory mechanisms that may promote the aforementioned effects will be examined, i.e. changes in immunological parameters, 'brain derived neurotrophic factor' (BDNF), and oxytocin.
The main objective of this study is to examine the efficacy of a new psychological intervention, called Back2School, in helping youths with problematic school absenteeism to return to school. Furthermore, the study will examine how well this program fares against the treatment or interventions that are usually given to youths with school absenteeism (treatment as usual or TAU). Based on previous studies we hypothesize that the Back2School intervention will be better at improving levels of school attendance as compared with treatment as usual (TAU).
In this feasibility RCT of the modular and flexible cognitive and behavioural therapy (Mind My Mind, MMM) compared with treatment as usual, the overall research aim was to explore the trial design and the acceptability of the assessments, interventions and outcome measures among children, parents, teachers and therapists, and secondly to provide data to estimate the parameters required to design a definitive RCT.
This study is designed to evaluate a novel online tool to deliver computerized Cognitive Behavioral Therapy (CBT). Participants will be randomized into three groups: experimental, active control, and waitlist. Participants in the experimental group will have access to the full-featured online tool designed to deliver CBT in an interactive and personalized manner. The participants in the active control group will have access to a limited version of the online tool designed to deliver basic CBT in plain text format. The waitlisted participants will be put on a waitlist for 6 weeks. We hypothesize that the experimental group participants will show a significantly higher reduction in depression symptom severity and will show increased engagement and adherence to the online tool.
The adverse effects of poverty at the individual, family, and community level on health outcomes for children are well-established. Material hardship, defined as difficulty meeting basic needs such as food, housing, and consumer goods, has been shown to have negative physical and emotional effects on both children and their parents. Diaper need, defined as a lack of sufficient supply of clean and dry diapers, is an example of a material hardship. Community-based studies of low-income families have demonstrated that between 30-50% of caregivers of young children expressed diaper need. Some of these caregivers with diaper need reported reducing diaper changes, a practice that is associated with diaper dermatitis and urinary tract infections (UTIs). These community-based studies have also shown that diaper need is associated with maternal depression and parental stress, even after adjusting for demographic factors and food insecurity. Diaper need may be a specific modifiable marker of caregiver stress and depression, beyond its role as an indicator of poverty. In this pilot, randomized controlled trial of low-income newborns and their caregivers the investigators will test the feasibility of supplying diapers as an intervention to infants in low-income families and assess if it can improve both a child's health and their caregiver's overall health.
This study will examine whether an Internet-based Acceptance and Commitment Therapy (ACT) intervention is effective, firstly, on reducing depressive symptoms, and, secondly, on improving well-being of elderly family caregivers. In our study, we will compare 1) the experimental Internet-based ACT group to 2) standardized institutional rehabilitation carried out in rehabilitation centers and to 3) support provided by voluntary family caregiver associations
The purpose of this study is to examine two mechanistic changes: emotion processing (awareness, expression and acceptance) and cholinergic anti-inflammatory processes (HRV and cytokine expression) through which an Art Therapy (AT) intervention reduces depression, pain and fatigue.
The Mindfulness Intervention as Myocardial Infarction Rehabilitation Additive (MIMIRA) study aimed at studying the feasibility and acceptability of Mindfulness Based Stress Reduction - an 8 week course in meditation and yoga - in patients with a recent coronary artery event and elevated depressive symptoms. To address these questions patients with elevated scores on a depression scale were invited to participate in MBSR, and there evaluation of the course as well as a panel of psychological risk factors and resources was measured.
This study aims to pilot test an 8-week, self-administered dyadic (couples-based) positive psychology intervention for couples coping with stroke using a randomized, waitlist control design. Mood and well-being will be assessed pre- and post-intervention, and at 3-month follow-up. It is expected that both partners will demonstrate improvement in mood and well-being.
There is literature to support both the need for and efficacy of brief interventions for depressive symptoms, particularly among college students.Brief behavioral activation interventions (BATD) have gained recognition as efficacious treatments for depression; yet a recent study evidenced a substantial (39%) non-response rate (Kuyken et al., 2017). In accordance with behavioral models of depression, the treatment involves increasing activity and positive experience, to break the negative reinforcement cycle maintaining depressed mood. Thus, strategies that may facilitate increasing activity may improve BATD outcomes. The objective of the current study is to examine whether briefly practicing a target activity during an activity planning session (modified single session of BATD) increases the likelihood of completing the activity during the upcoming week. We hypothesized that guided activity practice may improve self-efficacy within session and activity completion in the upcoming week. We further aim to explore whether activity completion mediates depressive symptom change.
