Uniquely, this book aims to provide students and practitioners with a knowledge base in relation to child sexual abusers which is focused on practice - assessment, treatment and evaluation - but rooted in psychological theory. Its strength lies in the simplification and outlining of a coherent approach to this group of offenders that is afforded by the single-author treatment, particularly so given that this author has developed and managed a sex offender project in South East London which is now one of the largest, longest running, and most thoroughly evaluated in the country.
