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.

A Collaborative Care Program to Improve Treatment of Depression and Anxiety Disorders in Cardiac...
DepressionGeneralized Anxiety Disorder1 moreFor this trial, the investigators propose a prospective trial of a collaborative care program to identify and treat depression, generalized anxiety disorder, and panic disorder among patients admitted to the hospital for an acute cardiac illness (acute coronary syndrome, congestive heart failure, or arrhythmia). Such assessment and treatment for depression/generalized anxiety disorder/panic disorder will begin in the hospital, and ongoing management will continue for six months following discharge. The investigators hypothesize that this model will lead to increased treatment rates, improved mood, reduced anxiety, and improved medical outcomes in this vulnerable population. If this model is effective, it could be implemented clinically to provide better and more complete care to patients hospitalized with acute cardiac illness, for whom depression and anxiety may be a risk factor for complications and death. This will be a two-arm, single-blind randomized controlled trial, with one-half of patients randomized to collaborative care and one-half randomized to the control condition (usual care). Psychiatric treatment in the intervention arm will be provided in concert with patients' primary care physicians-with primary care physicians prescribing all medications-within a framework supervised by a psychiatrist. The investigators will enroll patients who have any (or all) of the three included psychiatric diagnoses to improve the utility of the intervention. The investigators have chosen to enroll patients with several different cardiac diagnoses. This will allow the researchers to include patients with heterogeneous diagnoses and illness severity to determine if our intervention is effective in a broad population of patients with heart disease. The investigators will study an intervention targeting depression, generalized anxiety disorder, and panic disorder: all three disorders are disabling and associated with adverse cardiovascular outcomes, treatments for the conditions are highly similar, the investigators can treat patients who have more than one disorder, and a prior outpatient program successfully simultaneously addressed more than one mental health condition. The project will involve: (1) screening patients for depression, generalized anxiety disorder, and panic disorder as part of usual clinical care, (2) evaluation of positive-screen patients by a study social work care manager, (3) a multicomponent in-hospital intervention (for collaborative care patients) that involves patient education, specialist-provided treatment recommendations, and a goal of in-hospital treatment initiation, and (4), after discharge, continued phone-based evaluation and care coordination with primary care physicians to provide stepwise treatment in the collaborative care arm. The intervention has been designed to be low-cost, low-burden, and easily generalizable to other settings.
Quetiapine in Co-Morbid Depressive and Anxiety Disorders
Major Depressive DisorderDysthymic Disorder5 moreThis multi-centred study will be conducted at three centres. The design will be a randomized, placebo-controlled, parallel-group one. This investigation will evaluate the efficacy of add-on Quetiapine XR (extended release) treatment for patients who meet diagnostic criteria for depressive disorders and one or more comorbid anxiety disorder.
A Study Of Sertraline Compared With Paroxetine In The Treatment Of Panic Disorder
Panic DisorderTo evaluate the efficacy and safety of sertraline compared to paroxetine in patients with panic disorder.
Internet-Versus Group-Administered Cognitive Behavior Therapy for Panic Disorder
Panic DisorderPanic Disorder with or without agoraphobia (PD/A) is a common, and unless it is treated, often chronic psychiatric disorder. The are effective pharmacological as well as psychological treatments for PD/A. Because of the lack of availability of the most effective psychological treatment, cognitive behavior therapy (CBT), self-help based CBT treatments have been developed. One of those are Internet-based CBT. The aim of this study is to compare the effectiveness of Internet and group CBT for PD/A in a regular psychiatric setting. 113 patients are consecutively and randomly assigned to either treatment (both lasting 10 weeks). The main outcome measure is the Panic Disorder Severity Scale(PDSS). The study hypothesis is that treatments will show equal effectiveness.
Breathing Regulation Training for Individuals With Panic Disorder
Panic DisorderThis study will compare two different breathing regulation techniques to determine which is more effective in reducing the rate of panic attacks in people with panic disorder.
Study Comparing Venlafaxine vs. Paroxetine in Panic Disorder
Panic DisordersThe purpose of this pilot study is to evaluate the improvement in social function following therapy with venlafaxine extended release (XR) in the treatment of panic disorder (PD) in comparison to paroxetine. An additional purpose of this pilot study is to obtain the tolerability of using venlafaxine extended release (XR) in the treatment of panic disorder (PD) in comparison to paroxetine.
