The material available for this study covers the largest cross-section of children as they are seen in mental hygiene clinics: children who are referred by every variety of public and private child-care agency; who have come to the attention of the juvenile part of the Police Bureau or the Children's Courts: who are seen in the course of private practice or are confined for observation in psychiatric wards for adolescents, or are confined for physical diseases in pediatric wards, or seen in pediatric clinics.
