This document contains an introduction by Richard D. Krugman and five papers from the Adolescent Sex Offender Work Group meeting, which provide an overview of the present status of treatment programs for adolescent sexual offenders, methodological and ethical issues in research on etiology and treatment, and perspectives on research from those working with these adolescents. Chapter 1, "Recent Developments in the Treatment of Adolescent Sex Offenders" (Fay Honey Knopp), discusses the status of treatment facilities for adolescent sexual offenders in the United States and advocates restorative rather than punitive approaches to adolescent sexual offenders. Chapter 2, "Methodological and Ethical Issues in Evaluating and Treating Adolescent Sexual Offenders" (Judith V. Becker and Gene G. Abel), reports the results of studies on adolescent sexual offenders and discusses problems and ethical issues in doing research on offenders. Chapter 3, "The Adolescent Sexual Offender: Background and Research Perspectives" (Robert E. Freeman-Longo), presents the perspective of one working in a closed treatment facility. Chapter 4, "Adolescent Sexual Offenders: An Outpatient Program's Perspective on Research Directions" (Michael O'Brien), describes an outpatient treatment program and offers a useful classification of various types of adolescent offenders. Chapter 5, "Juvenile Sexual Offenders: A Family Systems Paradigm" (Caren Monastersky and Wayne Smith), reviews some accepted principles in the field, describes one approach to working with adolescent offenders, and provides a sexual offense continuum useful in designing therapy.
