Interestingly, there was a large cross-sectional study conducted in 2020 of Canadian children, youth and parents, where 67% to 70% of children and adolescents experienced deterioration in at least one mental health domain: depression, anxiety, irritability, attention hyperactivity and OC disorders, but 19% to 31%, depending on the age group, experienced improvement in at least one domain.
Do any of the witnesses have any comment—perhaps, Dr. Afifi—on what factors might explain this heterogeneity of experiences among Canadian children?
