This work deals with the phenomenon of juvenile delinquency, focusing in particular on the prevention and rehabilitation of affected adolescents. The approach to this topic is done in three steps. First, in addition to the terminology juvenile delinquency itself, important themes are placed into focus, which are associated with this phenomenon, such as how the discursive construction of youth can be detected and which different actors are involved. Subsequently, possible causes are discussed, which can lead to (youth) crime. Socialization in the social environment, socialization in subcultural contexts, anomie theory, and labeling approaches are focused here. The last part deals with prevention. First, it is explained how government sanctions can be seen as prevention and what impact they have on affected adolescents. Furthermore, it is shown what the social work response to how to deal with criminal youth is. Various social constructive measures and their rehabilitating effect are explained here.
