Biographical work is a relevant method of social work. From a holistic point of view, this method is used far too less in the different fields of social work. Most of the time biographical work is applied in social-pedagogical contexts, while it can also be very helpful in other areas, for example regarding delinquency. Throughout this bachelor thesis it will be discussed in which ways biographical work with adolescents can support their resilience. There will be a special focus on delinquent behaviour, so resilience can be understood in this context as a wide range of alternative behaviour besides delinquency.
