Brown (Medical U. of South Carolina) introduces this handbook's 38 chapters by explaining how provision of mental health care to youth has paralleled changes in other areas of health care. For example, schools must face the fact that 10-15 percent of US school children have a chronic medical condition that may be influenced by lifestyle. Contributors discuss working with schools to prevent and manage health problems and their psychological sequela; early identification and intervention efforts; and conditions encountered in school settings from asthma to AIDS. Other topics addressed include peer relations, professional training, and ethical and legal issues.
