About Dr. Stewart

Dr. Evelyn Stewart is an Associate Professor in the Department of Psychiatry, University of British Columbia and is the founding director of the Pediatric Obsessive-Compulsive Disorder Clinic and Research Program at BC Children and Women’s Health Centre. She is a clinical, genetic and neuroscience researcher, as well as a child and adolescent psychiatrist.

Her research focuses on biologic, phenotypic, familial, and treatment aspects of childhood-onset neuropsychiatric disorders, such as obsessive-compulsive disorder (OCD). Dr. Stewart has authored over 70 original papers, reviews and chapters on genetic, clinical, and treatment aspects of OCD, Tourette's Disorder, and related illnesses. She sits on the Scientific and Clinical Advisory Board of the International OCD Foundation and was previously on the Medical Advisory Board of the Tourette Syndrome Association of America and Co-director of the International OCD Foundation Genetics Collaborative.

At BCCHR, she leads the BB&D theme and co-leads the Mental Health group.

Current Projects

Neural Correlates in Childhood-onset OCD: The goal of this study is to evaluate for neurocognitive and neurosoft sign state and at-risk trait markers for OCD, by examining affected, at-risk and healthy youth.

Brain Function and Structure in Pediatric Obsessive Compulsive Disorder: The goal of this study is to examine the cortical structure and functional activation in the regions implicated in OCD in OCD-affected, OCD-unaffected siblings, and healthy children and adolescents. A planning task conducted pre- and post-symptom provocation will be used to examine the impact of symptoms on executive function. In addition, DTI will record white matter structure and organization.

As Principal Investigator:

Obsessive-Compulsive Disorder (OCD) Registry and DNA Repository
Clinical Outcomes following Group-based Family Cognitive-Behaviour Therapy in Pediatric Obsessive- Compulsive Disorder (OCD).
Mindfulness Training versus Peer Support Groups for Parents of Obsessive-Compulsive Disorder
Objective measures of sleep and daily physical activity in pediatric Obsessive-Compulsive Disorder

As Co-Investigator:

Cognitive and biological underpinnings of delusions in psychosis
Trends in Psychiatric Seasonal Emergency Admission


2010-current, NIH-RO1, Perspectives on Neuroimaging and Genetics from Parents of Children with OCD. The goal is to examine experiences of parents involved in Pediatric neuroimaging studies. Role: Co-Investigator.

2012-2020, MSFHR Clinical Research Scholar Award, $90,000/year or ($635,000 for 8 years), OCD translational multi-modal research program. The goal is to create an interdisciplinary, multimodal research program within the new Pediatric OCD clinic at B.C. Children’s Hospital. Role: Principal Investigator.

2014-2016, CIHR Operating Grant, $175,485/year ($526,454 for 3 years), Neural Correlates in Childhood-onset Obsessive-Compulsive Disorder. The goal is to compare neural correlates in CO-OCD and unaffected, at-risk sibling (SIB) groups with matched healthy controls (HC), in order to evaluate both their suitability as trait markers of genetic risk (to better understand the disorder) and their potential utility in clinical settings (to better manage the disorder). Role: Principal Investigator.
