Anxiety Treatment and Research Clinic (ATRC)

What this program does...

The Anxiety Treatment and Research Clinic's (ATRC) mission is to provide excellence and leadership in evidence based clinical service, education and research for anxiety disorders.

Our team of experts offer comprehensive evaluations and proven treatments for anxiety-related conditions. Treatments at the ATRC include both medications and effective psychological treatments. Our interdisciplinary staff is available to consult with your family doctor, psychiatrist and other professionals who are involved in your care. A physician referral is required to access care at the ATRC – for more information on how to access the clinic, please review our Referral Section.

"Anxiety Disorder" is an umbrella term that covers several different presentations of anxiety characterized by irrational and excessive fear, apprehensive and tense feelings, difficulty managing daily tasks and/or distress related to these tasks. Research shows that up to one in four adults has an anxiety disorder sometime in their life, and that one person in 10 is likely to have had an anxiety disorder in the past year. Anxiety disorders are the most common mental health problem in women, and are second only to substance use disorders in men.*

At the ATRC we care for people with the following conditions:

  • Panic Disorder
  • Agoraphobia
  • Social Anxiety Disorder
  • Obsessive Compulsive Disorder
  • Generalized Anxiety Disorder
  • Specific Phobias

And in some circumstances, we have limited treatment options for:

  • Posttraumatic Stress Disorder

How this program helps...

The good news about anxiety disorders is that they are treatable.

We provide treatments that have been evaluated by research to be effective in the treatment of anxiety disorders.  We also provide monthly "booster groups" for people who have completed our treatment program and want additional support.  See the booster group schedules listed in the Support Group section below. 

The ATRC is committed to providing learners from various health care disciplines with training in state-of-the-art assessment and treatment methods for anxiety disorders to develop the expertise of future health care professionals to address anxiety-related problems and increase the accessibility of treatment options. As such, psychology or psychiatry residents and other closely supervised trainees regularly provide assessments and treatments.

We continually evaluate the treatments that we provide, so in the course of your treatment you may be asked to complete questionnaires or participate in other studies. Participation in any research study is completely voluntary.  The Hamilton Integrated Research Ethics Board at St. Joseph’s Healthcare Hamilton and McMaster University has approved all studies conducted in our clinic.

We carry a full line of books on anxiety disorders and related topics for professionals and self-help.  You can purchase a book from our clinic's waiting room at the West 5th campus, or at the Outpatient Pharmacy located in the Main Lobby of St. Joseph's Healthcare Hamilton, Charlton Campus. You may also find them at the public library, order them online, or from your local bookstore.  Please see the ATRC Bookstore section on this website for a list of available books for sale.

Booster Groups  -  Please note that due to ongoing physical distancing requirements during the Covid-19 Pandemic, we have now moved our Booster Groups to an online format using the secure video platform Zoom. Anyone wanting to participate in a Virtual Booster Group will need to meet the following requirements:

  - Access to a secure Internet connection and a device such as a smartphone, laptop, desktop, tablet, etc with a camera feature.

  - Be registered for a MyDovetale account (see details below)

  - Access to a private space for the duration of the group where no one else can hear or see others on camera (we encourage the use of headphones if possible). This is to provide privacy and confidentiality for all members joining the group.

The time of our Booster groups has been changed to 3:30pm-5:00pm. 

If you are interested in participating in Virtual Booster Groups, REGISTRATION AHEAD OF TIME IS NOW REQUIRED.  We are not currently able to offer the Virtual Booster Group as a drop-in program.  You must call to register by 5pm the day before group in order to participate but we strongly encourage registering earlier.

We are continually trying to learn more about the causes of anxiety and the best ways to help people to overcome their anxiety problems. Our staff is internationally known for publishing numerous books and scientific papers on the nature and treatment of anxiety disorders. Through research at the ATRC and similar clinics around the world, there have been enormous advances in the treatment of anxiety in recent years.

Eligibility for participation in these studies is determined by clinical and research staff following your initial assessment.  Participation is never mandatory, and a decision to decline study participation will in no way detract from or interfere with your treatment.

All studies at the ATRC have been reviewed and approved by the Hamilton Integrated Research Ethics Board at St. Joseph's Healthcare, Hamilton and McMaster University.

Current Projects at the ATRC 

Validation of the Diagnostic Assessment Research Tool (DART) for DSM-5 Disorders

Contact: Elizabeth Pawluk, Psychologist; Luke Schneider, Psychologist, or Natalia Musielak, Research Assistant

The Diagnostic Assessment Research Tool (DART) is a new diagnostic interview created by psychologists at St. Joseph’s Healthcare Hamilton to assess common mental health disorders. The DART is intended for use in both clinical and research settings, while also minimizing burden and inconvenience for patients and researchers through its modular design. The goal of the present study is to evaluate the psychometric properties of the DART to ensure confidence in its ability as an assessment and research tool.

Individuals referred to the ATRC for a standard intake assessment will be invited to participate in the study, which will involve up to two study visits each lasting approximately two hours. Participants who complete the study will receive $30 in compensation for each visit as well as a complimentary parking pass.

Thinking Styles in Anxiety Before and After Treatment

Principal Investigators: Joelle LeMoult, PhD, UBC, local PI: Karen Rowa

The aim of this study is to help understand more about anxiety and the way people think and respond when in different moods. Participation in our study involves completing different questionnaires and computer tasks that are administered in a session before starting therapy for generalized anxiety disorder and then after therapy is complete. Participants are reimbursed for their time.

Endowment and Ownership in a Clinical Sample of Adults With Hoarding Disorder.

Principal Investigators: Karen Rowa and Noam Soreni                

The objective of this study is to better understand the development and persistence of ownership and psychological attachment to possessions for people with hoarding disorder. We are also interested in how people attach value to their personal possessions. Participants with and without hoarding disorder symptoms are asked to come into the ATRC for a single research session to complete computer tasks and paper and pencil tasks.

Investigating the cognitive and behavioural mechanisms of action of transcranial direct current (tDCS) stimulation in Obsessive-Compulsive Disorder

Principal Investigator: Noam Soreni, MD

Co-Investigators: Karen Rowa, Ph.D., C.Psych.; Randi McCabe, Ph.D., C.Psych.

We are investigating the use of a new and exciting technique called transcranial direct current stimulation (or, tDCS), which is a form of neuromodulation. In this study, we are aiming to assess the effects of tDCS on several cognitive and behavioural variables in order to gain information about how this technique might be helpful in the context of OCD. This is not being used as a treatment in this study. Participants must be currently enrolled in group CBT for OCD at the Anxiety Treatment and Research Clinic, and your group will be visited be research staff to collect information from interested individuals. Participants will be reimbursed for their time.
