Treatment of Social Anxiety in Youth
Social Anxiety DisorderThis research is designed to determine the effectiveness of attention bias modification for socially anxious children and adolescents. Over the course of 3 years, 50 youth will be enrolled in the trial.
Acupuncture on Anxiety and Inflammatory Events Following Surgery of Mandibular Third Molars
Tooth ExtractionMolar6 moreThe aim of this study was to compare the effect of acupuncture and placebo acupuncture for the control of pain, edema, and trismus following the extraction of third molars and control of preoperative anxiety. Patients who met the study criteria were randomized to the type of acupuncture (active acupuncture or placebo acupuncture) and to the side of the first surgery (right or left).
Transcutaneous Vagus Nerve Stimulation in Private Healthcare Center
Generalized Anxiety DisorderChronic Pain1 moreThis 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.
Internet-delivered Cognitive Behavioural Therapy in Arabic for Anxiety and Depression
AnxietyDepressionThe purpose of this study is to evaluate the efficacy of a culturally adapted internet-administrated cognitive behaviour therapy (ICBT) in Arabic for anxiety and depression
Effect of Mindfulness Meditation on Physiological Response to Unpredictable Stimuli
Anxiety DisordersGeneralized Anxiety Disorder5 moreThis 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.
Gaze Contingent Feedback for Anxiety Disorders in Children
Anxiety DisordersThe purpose of this study is to determine whether giving gaze-contingent feedback is an effective attention modification procedure, helping in the treatment of anxiety disorders in children.
Training Mental Habits Study
Generalized AnxietyWorryGeneralized Anxiety Disorder (GAD) is a chronic condition whose hallmark feature is excessive and uncontrollable worry (American Psychiatric Association, 2013). Theories of GAD propose that specific cognitive biases are involved in the maintenance and etiology of chronic worry. One cognitive bias that plays a role in worrying is abstract thinking, or the tendency to "verbalize" thoughts and worries in a manner that is vague and lacking in detail. There is evidence that training depressed people to think more concretely improves depressive symptoms and depression-type thinking styles, and reduces emotional reactivity. Given that chronic worry and depression have commonalities (e.g., repetitive thinking styles, difficulties with problem-solving and attentional control, emotion dysregulation), concreteness training may help people who struggle with chronic worry. The main goals of this proof of concept experiment are 1) to test in individuals reporting chronic worry the effects of an active form of concreteness training that involves imagery practice (compared to a no training control condition) on frequency of worrying, problem solving quality, and worry-related processes; 2) to examine the degree to which concreteness training causes improvements in daily worry and negative affect during the 7 days of practice. The study design will provide us with an understanding on a more "macro" level of the potential short-term benefits and will at the same time allow us to see, on a more "micro" level, how training concreteness affects worry and mood on a day-to-day basis during a 7-day period. The findings from this study will inform relevant clinical literature about efficacious methods to reduce chronic worry.
Novel Behavioral Intervention to Enhance Social Connections in Anxiety and Depression
Anxiety Disorders and SymptomsDepressionThe overall goal of this project is to develop a novel transdiagnostic behavioral treatment -- social approach training -- intended to enhance positive social connections in individuals with elevated anxiety and/or depression. Social relationship impairments are pervasive and debilitating consequences of anxiety and depression. Existing treatments have some beneficial impact on social functioning; however, many people continue to have few and/or poor quality relationships following treatment, even after experiencing symptom relief. This study will evaluate the effects of social approach training on the brain systems that have been shown to be important for establishing positive connections with others. Approximately 60 individuals (ages 18-55) seeking treatment for anxiety or depression will participate in this study. Participants will be randomly assigned with equal probability to one of two versions of social approach training (5 or 10 sessions) or a waitlist (assessment only) control group. Participants will be assessed at baseline and post-treatment and compared on measures assessing brain responses to social reward (primary outcome), as well as physiological, behavioral, and emotional responses to social reward (secondary outcomes). It is hypothesized that participants assigned to social approach training will display greater increases from pre- to post-treatment in activity in brain systems that regulate the processing of social reward (e.g., striatum) relative to participants in the control group. This study will also determine whether the 5- vs. 10-session versions of the treatment program result in meaningful differences, compared to each other, in how the brain responds to social reward.
Attention Bias Modification Training in Youth With Subthreshold Impairing Anxiety
AnxietyThis study is a pilot test of Attention Bias Modification Training (ABMT) among clinic referred children and adolescents with subthreshold impairing anxiety (i.e., anxiety and related impairment that fails to meet criteria for an anxiety disorder diagnosis). Half of participants will receive 8 sessions of computer administered ABMT and the other half of participants will receive a 8 sessions of a computer administered control task.
A Study of Duloxetine in Elderly Generalized Anxiety Disorder
Generalized Anxiety DisorderThe purpose of this study is to test the safety and efficacy of duloxetine versus placebo in elderly patients suffering from generalized anxiety disorder (GAD).
