Starting March 1, 2013, Dr. Peter Szatmari assumed the combined position of Chief, Child and Youth Mental Health Collaborative at the Centre for Addiction and Mental Health and The Hospital for Sick Children (Psychiatrist in Chief) as well as Director of the Division of Child and Youth Mental Health at the University of Toronto. Szatmari holds the Patsy and Jamie Anderson Chair in Child and Youth Mental Health.
Szatmari has made significant contributions to the Autism Spectrum Disorder field in many areas including diagnosis, measurement, genetics and longitudinal development – all of which led to significant changes in our understanding of ASD as well as the classification of ASD in both DSM IV and 5. He has also published more generally in psychiatric epidemiology and in clinical research in developmental psychopathology. More recently, he has turned his attention to developing evidence based, patient oriented systems of care for children and youth and evaluating innovative models of care using clinical trials methodology. He has been editor of several important journals in the field of child and adolescent psychiatry and has consulted to government agencies in Canada, the USA and the UK. He is the author of the book “A Mind Apart; Understanding Autism and Asperger Syndrome” and co-author of “Start Here: A Parent’s Guide to Helping Children and Teens through Mental Health Challenges”.
Szatmari is a trained clinical epidemiologist and started his career working on the Ontario Child Health Study (OCHS) reporting on the prevalence of ADHD. This was the first psychiatric epidemiologic study of children and adolescents in North America and the project as a whole had a large impact on mental health public policy in Canada and elsewhere. The oft-quoted figures that 1 in 5 Canadian children have a significant mental health challenge and that less than 15% of these children receive mental health services comes from the OCHS.
Dr. Szatmari has a long history of research in autism spectrum disorders (ASD). Currently he is running the largest follow up study of children with ASD assessing change in symptoms and functioning from early childhood to the end of adolescence.
More recently, he has turned his attention to clinical trials in child and youth mental health. He is the co-PI of a large CIHR funded pragmatic clinical trial looking at the extent to which an Integrated Collaborative Care Model in the community is more effective than usual out-patient care in improving impairment among adolescents with psychiatric disorders. He is also a co-investigator in several clinical trials in adolescent depression.
