Since to date there is no record of systematic experience in treating sex offenders by psychotherapy, this book fills a gap in the literature. It is especially important at a time when the courts have also called for the treatment - instead of merely the punishment - of these delinquents. For the first time a report of not only individual cases, but also of a methodical study of a large patient group is available. By combining copious case studies with statistical methods, clear and scientifically valid knowledge results. In terms of psychodynamics, both behavioural and counselling techniques have been applied. The book thus contributes significantly to the present discussion of methods beyond those of classical psychotherapy in the treatment of sex offenders.
