[Possibilities for inclusion of group music therapeutic methods in the treatment of psychotic patients].

Four types of music therapy (listening, singing, dancing and playing instruments) which can be combined to obtain a "graduated group-centred music therapy" are investigated in regard of their methodological and didactical organisation and their effects on a group of schizophrenics. Each of the therapy types acts in a different way on the variables "anxiety" and "activity". It seems possible to influence these variables during group-centered treatment and to lead the group towards modes of communication and behaviour that are more appropriate to reality.
