Ontario Child Health Study: Social and School Impairments in Children Aged 6 to 16 Years

This study reports on informant-specific prevalence rates and the relationship with psychiatric disorder of social and school impairments in a community sample of children, 6 to 16 years of age, in Ontario. Prevalence rates ranged from less than 1% to over 18% depending on informant, and there was a low level of agreement between informants. Although impairments were strongly related to psychiatric disorder, there were many children with impairments and no psychiatric disorder or psychiatric disorder with no impairments. Implications of these results are discussed.
