This book, written by staff members of the National Center on Child Abuse and Neglect (NCCAN) and of NCCAN-funded projects, presents their reflections about their experiences in providing, supporting, and evaluating treatment to abused and neglected adolescents. It is intended to serve as a source book for those concerned with the problem of adolescent maltreatment. Section I, Issues in Adolescent Maltreatment, contains four chapters on: (1) the meaning of the major issues of adolescence in relation to maltreated adolescents, and treatment considerations; (2) effective intervention strategies to prevent maltreatment; (3) services for the maltreated adolescent; and (4) issues related to the definition of adolescent abuse and neglect. Section II, Service Models, presents four community projects designed to examine specified forms of child maltreatment and specialized treatment approaches. Section III, Past, Present and Future Perspectives, contains three chapters dealing with the federal role in child protection, results of a study examining the impact on the community of the four adolescent maltreatment projects described in section II, and an analysis of supplemental data focusing on client characteristics in the four projects. The appendices include addresses of the adolescent maltreatment projects and a list of contributing authors. (KGB)
