The appropriate handling of aggression in the analytical psychotherapy of children and adolescents is consistently challenging. One is often confronted with truly archaic outbursts of aggression. After clarifying the concept of aggression within psychoanalysis and explaining some psychoanalytic theories, Hans Hopf illustrates treatment-related issues using case examples and presents various ways of dealing with young patients. He also addresses the personality of the analyst and issues of countertransference. For the new edition, the texts have been revised and supplemented with some considerations on ADHD, the psychodynamics of perpetrators, and xenophobia.
