Catalytic models developed through social work. 
The article develops the concept of catalytic processes in relation to social work with adolescents in an attempt to both reach a more nuanced understanding of social work and at the same time to develop the concept of catalytic processes in psychology.  The social work is pedagogical treatment of adolescents placed in out-of-home care and is characterised using three situated cases as empirical data.  Afterwards the concept of catalytic processes is briefly presented and then applied in an analysis of pedagogical treatment in the three cases.  The result is a different conceptualisation of the social work with new possibilities of development of the work, but also suggestions for development of the concept of catalytic processes.
