At the heart of these deficiencies is the lack of information on: 1) the prevalence of children¡¯s mental health problems in Ontario, and 2) the characteristics and outcomes of children receiving mental health services. In combination, the 1983 and 2014 Ontario Child Health Studies (OCHS) addressed this lack of information by identifying: 1) changes in the prevalence and determinants of child and youth mental disorder over the past 30 years, and 2) the continuing challenges with access and targeting of children¡¯s mental health services.4¨C1 %K children¡¯s mental health %K policy %K data %K information systems %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6463360/
