This report, sixth of a series of eight, focuses on the emotional health and well-being of children and youths. It discusses the prevalence of mental health problems among young people, development of mental health systems of care, and mental health benefits as a part of health insurance coverage. The California Center for Health Improvement asked California adults about how much they worried about mental health problems among children and youths in their community, and 65% of adults surveyed and 70% of parents were somewhat to very worried. Eleven percent of parents surveyed also reported having had a problem obtaining mental health services for their children. Researchers and clinicians agree that systems of care are needed to coordinate public and community-based mental health services for children and youths, including mental health assessment, early intervention, case management, crisis intervention, outpatient and inpatient care, school-based day treatment, in-home services, and family support. Some of the programs in California that are operating to meet these needs are described. Survey results show that California adults support expanded health insurance coverage and increased public funding to promote access to mental health services. Policy recommendations center on the coordination of services for children and youth, better health insurance coverage for mental health services, enrollment in Medi-Cal (medical assistance) for all eligible children and youths, implementation of the proposed Healthy Families program, and increased tax funding for mental health services.
