Scientific Research

The CIOCD promotes national and international clinical and research collaboration among OCD experts, and advancement of scientific research designed to inform best practice specialized treatment. Research supported by the CIOCD focuses on improvement in accessibility of timely evidence based specialized treatments for OCD and related disorders throughout the lifespan and on specialized interventions to improve rates of recovery for as many patients as possible. Ongoing research and recent publications by CIOCD committee members are available on request. Enclosed below are select publications in this field, some by the CIOCD International OCD Task Force (ATF*) and others in which CIOCD had no involvement.
