Obsessive Compulsive Disorder (OCD) Research Clinic

Obsessive-compulsive disorder (OCD) is a frequently debilitating psychiatric disorder that often goes undiagnosed and undertreated. The Yale OCD Research Clinic has a history of advances in research on this condition. Our current work, funded by the National Institute of Health, the Doris Duke Charitable Foundation, and other groups, continues this tradition, as we seek to better understand the brain processes that have gone awry in OCD, and to use this knowledge to ultimately develop new treatments.

If you are interested in volunteering for a study, you can find more information here. We have studies appropriate for people that have OCD, as well as people that do not have OCD.

Please note that we are not able to provide treatment services. If you are looking for more information on treatment providers in your area, the International Obsessive-Compulsive Foundation may be a useful resource.

Our studies are for participants age 18 and up. Those under 18 are referred to the Yale Child Study Center's clinic
