Ministry of Health to assess the health of parents and siblings of children who have a developmental disability. The study found strong evidence that parents and siblings of children who have a developmental disability experience higher odds of a depression or other mental health diagnosis compared to parents and siblings of children who do not have a developmental disability. In addition, there was evidence that in families with a child with a developmental disability, parents and siblings who are diagnosed with depression or another mental health problem visit physicians and/or the hospital to a greater extent than parents and siblings who are diagnosed with depression or a mental health problem but do not have a family member with a developmental disability. These findings indicate that parents and siblings of children who have a developmental disability are a vulnerable group in need of programs and services that support their mental health.enAvailable to the World Wide Webdevelopmental disabilitychildrenparentssiblingshealthdepressionmental healthThesis
