The editors of this book are among the world's leading authorities in the area of understanding and treating sex offenders. They address the biological, developmental, cultural, and learning factors in the genesis and development of sexual deviancy and link those theories to interventions with sex offenders. The book examines why sex offences are committed and covers the controversies surrounding what to do about these crimes. It discusses cutting-edge theoretical developments in etiology, rehabilitation and practice. The book is divided into two sections: The first covers explanations of sexual deviance, including ethical issues and classification systems for sexually deviant disorders. The second section addresses responses to sexual deviance including traditional and newer intervention approaches. This is an area fraught with controversies both within the clinical community and in the public policy sector, and the authors seek to discuss those issues that are particularly controversial.
