Center for Obsessive-Compulsive Treatment and Related Disorders

About Us

Founded in 1982, the Anxiety Disorders Clinic was the first in the nation devoted to research and treatment of anxiety problems. Although the idea that anxiety could take the form of specific disorders had been increasingly recognized, little systematic information about these disorders was available at the time. The clinic has been a driving force behind the recent advances in the recognition, understanding, and/or treatment of anxiety disorders such as posttraumatic stress disorder, panic disorder, social phobiaobsessive-compulsive disorder and others. Our counterpart Hispanic Clinic offers research treatment in Spanish and is a valuable asset in the community.

The OCD research program is dedicated to the mission of improving the lives of people with obsessive-compulsive disorder (OCD) and related disorders by conducting cutting edge research to transform how we understand and treat these disorders. For the patients of today, we examine how to combine and sequence current treatments to maximize outcome, and we explore novel treatments. For the patients of tomorrow, we collaborate with experts in neuroimaging, genetics, and basic science to examine what causes obsessions and compulsions.

Our Research Specialties

  • Obsessive-Compulsive Disorder (OCD) treatment
  • Exposure and response prevention (EX/RP; ERP)
  • Cognitive Behavioral Therapy (CBT)
  • Medication Treatment for OCD

Our Mission

Our mission is to improve the lives of people with Obsessive-Compulsive Disorder (OCD) and related disorders by conducting cutting edge research. For patients today, we study how to combine and sequence current OCD treatments to maximize outcomes, and we explore novel treatments. For the patients of tomorrow, we collaborate with imagers, geneticists, and basic scientists to examine the causes of OCD.

"I went to other therapists and psychiatrists and that just made it worse for me. This type of treatment was the best for me and was the only thing that actually helped." -- Client

"Such a friendly, caring and knowledgeable staff who are truly experts in OCD.  During treatment I actually experienced a freedom/lightness that I had never experienced before, which made me look at the world around me in a much different perspective.  A perspective that no longer saw everything as a worry or a fear, but rather as an opportunity and as a hope for a less rigid way of life." -- Client

Our OCD treatment studies:

All evaluations and treatment provided is at no cost to you and is delivered by our team of dedicated clinicians. We offer a variety of treatments, including cognitive behavioral therapy (CBT) consisting of exposure and response or ritual prevention (EX/RP or ERP), novel medications, and new ways of delivering CBT (e.g., via the internet). These treatments are available for individuals who have not received treatment, who have received treatment, and those who have not benefited from standard treatment.
