Filter by:The general purpose of the study is to determine whether yoga is an effective method for treating Generalized Anxiety (GAD), and its relative efficacy compared to a standard psychosocial intervention. This five-year multi-site study will examine the comparative efficacy of yoga, CBT, and stress education, a previously employed control condition, for patients with GAD. Across 2 enrolling centers (BU and MGH) 230 patients will be randomized with GAD to one of three 12 session weekly study treatments: 12-weekly yoga (n=95), CBT (n=95), or stress education (SE: n=40). Independent clinical assessments will occur before the 12-session intervention phase, at mid-treatment, after the intervention, and at 6-month follow-up. All clinician-rated outcomes will be assessed by trained Independent Evaluators (IEs) blind to treatment assignment.
This non-randomized, open-label study has the objective to study the effects and feasibility of Transauricular Vagus Nerve Stimulation (TaVNS) for patients suffering from Generalized Anxiety Disorder (GAD), Chronic Pain (CP) and Irritable Bowel Syndrome (IBS) in a private healthcare centre.
Generalized Anxiety Disorder (GAD) is a chronic condition that is characterized by excessive and uncontrollable worry and anxiety. In Canada, 3 to 4% of the population suffer from GAD at any point in time. These individuals have a lowered quality of life and are at risk for many medical conditions such as coronary heart disease and cancer. Research suggests that both pharmacological and psychological approaches are effective for treating GAD in the short-term; however, psychological treatments appear to offer the greatest long-term benefits. There exist a number of effective psychological treatments for GAD, most of which fall into the category of cognitive-behavioural therapy or CBT. In the 1990s, a group of Canadian investigators developed a CBT protocol for GAD that included four components. Data from five clinical trials suggest that one of the four components is particularly important for treatment success: experiencing uncertainty rather than avoiding it in everyday life. Stated differently, learning to tolerate and deal with uncertainty appears to be the key to decreasing worry and anxiety. Given this finding, the investigators have developed a new treatment that exclusively targets intolerance of uncertainty: Behavioural Experiments for Intolerance of Uncertainty or BE-IU. The goal of the current proposal is to test the efficacy of BE-IU (6 weekly treatment sessions) by comparing it to a Waiting List (WL) control condition (6 weeks). A total of 50 participants with a primary diagnosis of GAD will be randomly assigned to either BE-IU or WL and will be assessed at 4 time points ranging from pre-treatment to 12-month follow-up. The conditions will be compared in terms of treatment efficacy and mechanisms. The investigators will also examine the predictors of change during the 12-months following treatment. The proposed study will produce data on the efficacy and mechanisms of a treatment for GAD that is less costly, less complex and easier to disseminate than treatments that are currently available.
Transcranial Light Therapy involves non-invasive and invisible beams of light that increase energy metabolism in the brain. Transcranial light therapy has been found to promote brain metabolism which may help people with anxiety. The research team proposes a novel approach to treating anxiety by using transcranial light therapy.
The investigators are examining whether difficulties with cognitive control (i.e., the ability to stop one's thought process and shift attention) is a common problem across three types of repetitive, negative thinking: obsessions (as seen in obsessive compulsive disorder, OCD), worries (as seen in generalized anxiety disorder, GAD), and ruminations (as seen in major depressive disorder, MDD).
This trial attempts to evaluate the treatment efficacy of Simplified Cognitive Behavioral Therapy (SCBT) and its safety among schizophrenia patients. Half of participants will be randomized to accept SCBT.
Up to one-half of those in treatment for alcohol use disorder (AUD) has a co-occurring anxiety disorder ("comorbidity"), a condition that marks a high degree of treatment resistance, severity and relapse risk in AUD treatment patients. The investigators conceptualize comorbidity as a feed-forward system ("vicious cycle", [VC]) of interacting negative affect/stress, drinking motives/behavior, coping skills deficits, environmental circumstances, and neurobiological adaptations. Based on this model, the investigators developed and validated the VC cognitive-behavioral therapy (VC-CBT) to disrupt this system at several key linkage points. In a recently completed randomized controlled trial (RCT), the investigators found that adding the VC-CBT to standard AUD inpatient treatment resulted in better alcohol outcomes 4 months following treatment than did adding an anxiety treatment or standard AUD treatment alone. With a number needed to treat (NNT) index of 8 (relative to standard AUD treatment alone), the VC-CBT could, if broadly disseminated, have a large positive impact on AUD treatment. Unfortunately, several significant barriers related to the resource- and expertise-intensive delivery of the VC-CBT limit its dissemination potential and, hence, the impact of this otherwise effective treatment. Therefore, to maximize the public health and scientific potential of the investigators work, the investigators propose to adapt the therapist-delivered VC-CBT to a computer-delivered format to facilitate reliable and economical dissemination of the VC-CBT while maintaining its established efficacy.
Pragmatic trial of pharmacogenetic testing at the time of prescription for a selective serotonin reuptake inhibitor, tricyclic antidepressant or atypical antipsychotic. Does real time intervention improve patient outcomes?
Drs. from the Mayo Clinic Rochester will plan and execute a feasibility study of the phase I prototype version of the Virtual Reality exposure therapy system. Dr. X, who has significant experience in evaluating patient experiences and opinions of technologies intended to change behavior, will oversee a qualitative study to examine the prototype system. Twenty children with generalized anxiety disorder with perfectionism who have received less than 3 treatment sessions and a parent will be recruited to pilot the Virtual Reality system.
This study will evaluate the effects of Mindfulness-Based Stress Reduction (MBSR) on physiological reactivity. This study will focus on individuals with anxiety who will participate in an 8-week MBSR class. The investigators will test participants' reactivity to both predictable and unpredictable stimuli before and after the class to understand the physiological changes that may occur after to the intervention. Secondary measures include psychometric instruments and a delay discounting task.
