First published in 1998. This is Volume IX of the twelve in the Sociology of Youth and Adolescence series and explores the theory, case studies and treatment of juvenile delinquency using a psycho-analytical method. During recent decades the problem of delinquency has been approached scientifically from various angles. It has been considered as a social problem, as a penological and criminological problem and-from the point of view of the individual offender as a psychological problem. This book is an attempt to show which problems in the vast field of research in delinquency can be solved by psychoanalysis; and in what way sociological and criminological research workers can make use of psycho-analytical findings in order to further their own investigations.
