Social networks, social capital, i.e., network-accessed resources, and neighbourhood environments have been shown associated with a range of health behaviours and conditions, including obesity, physical activity, nutrition, and mental health. Research on social capital and health in Montreal has shown the importance of network social capital for a person's subjective health status, sense of control, self-reported physical activity, and obesity. Research has also shown high social capital to reduce health service use, mental health service use, and improve the management of chronic illnesses. Despite advances in the understanding of social capital and its link to health and health service use, most research on social capital is cross sectional and is unable to identify the causal pathways linking social networks and capital to health and health care use. Longitudinal research would strengthen the evidence base for designing interventions to prevent or delay the use of health services, particularly in older adults. This research has three main objectives: (1) transform the original sample of Montreal Neighbourhood Networks and Healthy Aging (MoNNET-HA) households (n=2707) into a panel study, (2) link the MoNNET-HA participant data to their Quebec Health Insurance Registry (Régie de l'assurance maladie (RAMQ)) information, and (3) assess the feasibility of extending the MoNNET-HA panel by one wave to include participant's core network members. Unique about the original MoNNET-HA sample is that it purposefully oversampled older adults (> 64 years old) but remains representative of Montreal adults at various ages and income levels. In addition, MoNNET-HA data is integrated into a GIS database which allows researchers to examine the effects of neighbourhood environmental characteristics on health. By linking MoNNET-HA data to RAMQ, researchers will be able to examine patterns of diagnosed health conditions, (e.g., fractures, depression), pharmaceutical use and adherence, and formal health care use over time. Transforming the cross-sectional study into a panel study would also allow researchers to examine longitudinally the dynamics of health and health care utilization among Panel participants over the life course, and the causal pathways linking neighbourhoods and networks to health and health care use.
The long term follow up of a pilot study in which the invesitagors proposed to test whether high frequency stimulation of the subcallosal cingulate (SCC) is a safe and efficacious antidepressant treatment in five TRD patients, to compare the effects of left-sided vs. right-sided stimulation, and to investigate potential mechanisms of action of this intervention. Importantly, this study will be used to assess the need for and assist in planning a larger, more definitive trial of SCC DBS for TRD.
This study is a randomized controlled trial studying the efficacy of an iCBT treatment for patients with chronic pain and comorbid psychiatric distress. Half the participants will receive treatment at first, while the other half serve as a control group. After the first group has received treatment, the same program will be offered to participants in the control group. Treatment will be tailored on the level of individual participants, enabling individuals suffering a wide range of problems to be recruited. The treatment will consist of a 10-week guided self-help program, followed by a booster program and follow-up one year later. During the curse of the treatment the participants will be guided via text communication by a licensed psychologist or a candidate psychologist on their last year of studies. The primary hypothesis is that an individually tailored CBT-treatment administered through the internet can be beneficial for patients suffering from chronic pain and comorbid psychiatric distress. The investigators expect that patients in the treatment group will show reduced levels of disability, depression and anxiety, while improving on scales measuring coping and quality of life.
The purpose of this study is to compare two talking forms of therapy designed to help reduce depressive symptoms in teenagers: Interpersonal Psychotherapy for Adolescents and Treatment as Usual.
Depression is among the world's leading causes of disability. To fill the existing treatment gap, psychological online interventions (POIs) and Internet-based treatment, including bibliotherapy with PDF manuals (POIs), are increasingly recommended as they are easily accessible and deemed an initial alternative approach. The present trial aims to evaluate imagery rescripting. With the help of various techniques, the approach aims to edit negative memories and rewrite a "happy end". To the best of our knowledge, imagery rescripting has never been tested as a self-help intervention. A large sample of patients with primary or secondary depression (N = 120) will be recruited and randomly allocated to either the intervention group or a wait-list control group. The intervention group consists of two subgroups that will receive either a full or brief version of a manual teaching them imagery rescripting. Participants will be assessed at baseline and six weeks later. A follow-up assessment will be completed six months later. The primary outcome measure is the Beck Depression Inventory II.
The French E3N cohort was initiated in 1990 to investigate the risk factors associated with cancer and other major non-communicable diseases in women. The participants were insured through a national health system that primarily covered teachers, and were enrolled from 1990 after returning baseline self-administered questionnaires and providing informed consent. The cohort comprised nearly 100 000 women with baseline ages ranging from 40 to 65 years. Follow-up questionnaires were sent approximately every 2-3 years after the baseline and addressed general and lifestyle characteristics together with medical events (cancer, cardiovascular diseases, diabetes, depression, fractures and asthma, among others). The follow-up questionnaire response rate remained stable at approximately 80%. A biological material bank was generated and included blood samples collected from 25 000 women and saliva samples from an additional 47 000 women. Ageing among the E3N cohort provided the opportunity to investigate factors related to agerelated diseases and conditions as well as disease survival.
Late-life depression is a significant public health concern, and effective interventions for prevention and treatment are needed. Insomnia and inflammation are modifiable targets for depression prevention, and this study is significant in using an experimental approach (i.e., inflammatory challenge) to probe acute inflammatory- and depression responses as a function of insomnia, which will inform identification of molecular targets for pharmacologic interventions, and improvement of insomnia treatments to prevent depression in older adults. Project
This is an individually randomised control trial to assess the effectiveness of a livelihoods and social empowerment intervention, delivered by Women for Women International, on married women's experiences of intimate partner violence in Afghanistan. It has a 22 month follow up.
To determine associations between dietary factors and risk of major chronic diseases and their risk factors
In essence the researchers are hoping to test two separate hypotheses (described below in the form of research questions). Therefore, the proposed analysis has been outlined according to each hypothesis. Hypothesis 1: Is low-dose quetiapine (50 mg/day) more effective for patients with depression who have insomnia at treatment baseline? (Stated differently: is low-dose quetiapine 50 mg/day effective as monotherapy for patients with depression regardless of whether or not they have insomnia at baseline?). Hypothesis 2: Is high-dose quetiapine (150 - 300 mg/day) more effective for patients presenting with melancholic depression at treatment baseline?
