Core Team Research Programs

Program Area Emerging Research Questions Lead
Contextual (Neighbourhood & Family) Effects on Child Mental Health 1. To estimate and account for neighborhood variability in the strength of association between family poverty and the emotional-behavioral problems of children and adolescents.

2. To test the hypothesis that relative disadvantage (children and adolescents in poor families living in wealthier neighborhoods) is associated with increased emotional-behavioral problems in relation to poor children living in poorer areas.

3. To evaluate the ability of the 2014 OCHS to disaggregate variability in child and adolescent emotional-behavioral problems cross-classified by where they live and what school they attend.

Michael Boyle
Child health disparities: the role of migrant background and race/ethnicity


1. To examine differences in the prevalence of child and youth mental disorder and service utilization by migrant background (immigrant, refugee) and race/ethnicity

2. To identify individual and contextual level factors that contribute to mental health care disparities among children and youth from migrant and racial/ethnic minority backgrounds

3. To examine the extent to which the concentration of foreign-born individuals in a neighborhood conditions level of risk for mental disorder among children and youth from migrant versus non-migrant families

Kathy Georgiades
Effects of Socio-Economic Determinants (Income, Social Assistance, Housing) & Comparisons with 1983 1. To estimate variation in the effects of housing tenure on child emotional-behavioral problems across neighborhoods and identify neighborhood characteristics that might explain this variation.

2. To examine the extent to which dwelling satisfaction is associated with child emotional-behavioral problems.

3. To examine whether the age at which young parenting creates risks for child emotional-behavioral problems has changed between 1983 and 2014.

Jinette Comeau
OCHS Checklist Measurement Development

Service Use, Service Targeting & Resource Allocation (Thesis papers)

1. To determine whether gaps between child mental health need and child mental health agency service use exist based on data from the 2014 OCHS. Do they vary by MCYS service area? What are the individual, family and area-level characteristics predictors of this service gap?

2. To examine how child mental health service expenditures vary across the province and to what extent are variations in expenditure are explained by child mental health need.

3. The Ontario Child Health Study Emotional Behavioural Scales: A Checklist for Measuring Selected DSM-5 Disorders

Laura Duncan
Multilevel SEM with OCHS data

Health Service Efficiency

MOHLTC Admin Data Linkage Projects

1. To examine the agreement between PMK-reported child mental service use and service use based on administrative data.

2. To examine the overall production efficiency of MCYS-based child mental health services and the determinants of the efficiency.

3. To examine social disparities in child mental health service use.
