Three papers in this month's issue examine services for children. In the State Health Care Reform column, Marcia C. Peck, M.D., M.P.H., describes the evolution of parity laws in California since 1983, especially as they apply to children. The most current law, enacted in 1999, mandates equal coverage for the diagnosis and treatment of nine severe mental illnesses and serious emotional disturbances among children (see page 743). Dana A. Weiner, Ph.D., and her associates found high rates of substance abuse among children and adolescents with serious emotional or behavioral disturbances who were in residential treatment. These children were significantly more likely to be at risk of suicide, elopement from residential treatment, and discharge to institutional placements (see page 793). In another study of children's services, Marc Navon, M.S.W., L.I.C.S.W., and his associates found that the Pediatric Symptom Checklist was a simple and reliable tool for identifying youth in primary care settings who were at risk of behavioral health problems. They describe a strategy to help professionals recognize and address children's unmet mental health needs (see page 800).
