Introduction to knowledge and competency standards for specialized treatments for obsessive-compulsive disorder throughout the lifespan: Phase two series by the International Accreditation Task Force of the Canadian Institute for Obsessive Compulsive Disorders (CIOCD, www.ciocd.ca).

This paper presents an introduction to the phase two series of papers by the 14 nation International Obsessive-Compulsive Disorders Task Force (ATF) of the Canadian Institute for Obsessive Compulsive Disorders. These papers present evidence-based knowledge and competency standards developed by the ATF for specialized treatments for obsessive-compulsive disorder (OCD) through the lifespan, operationalized as clinician abilities. Specialty standards for OCD do not currently exist and are deemed by experts to be foundational to transformative improvement globally in quality and accessibility of evidence-based treatments for this crippling disorder. Currently available guidelines for care are deemed to be essential but insufficient because of highly variable clinician knowledge and competencies specific to this disorder. The ATF standards encompass specialized cognitive behavior therapy, and pharmacotherapy, for pediatric and adult OCD. Evidence-based methodology with integration of expert opinion are described. Upcoming ATF phases three and four will involve development and implementation of training criteria and processes for certification (individual clinicians) and accreditation (clinical sites) based on the ATF standards. These standards will require periodic review and updating commensurate with advances in clinical research. We hope that this international initiative constitutes a significant step forward to inform and advance evidence-based specialized treatment and training for OCD.
