Schema therapy can be seen as an extension of cognitive behavioural therapy by which aspects of other therapeutic movements can be integrated into therapy. Schematherapy deals with so-called "schemata", i.e. complex patterns of thought and behaviour that have been learned during key emotional situations in development. After traumatic experiences, chronic frustration or when basic needs are not met in the long term, "maladaptive", negative schemata emerge that appear again and again in new situations and lead to problems. In schema therapy these negative schemes can be worked on and changed. This form of therapy is particularly effective in children and adolescents and is based on intense relationship work between the child, parents and therapist. Various child-friendly techniques such as hand or finger puppet games, sketches, role playing and imagination exercises are used.
