The Mental Health Questionnaire for Children and Youth (MHQ-CY) uses the OCHS-EBS and associated population norms to assess mental health disorder symptoms. The MHQ-CY refers to a suite of brief, self-completed questionnaires for youth (aged 12 to 17) and parents/caregivers (of children/youth aged 4 to 17), which assess the characteristics and mental health-related needs of children/youth and their families seeking help from children’s mental health agencies in Ontario.

There are 10 versions of the MHQ-CY:
