ABSTRACT
The history of group psychotherapy in the psychoses is connected to that of sociological and psychosocial research of the groups in addition to that of the history of group therapy in general and to the more extensive history of the psychotherapy of the psychoses. Three stages in the history of group psychotherapy in the psychoses can be differentiated: a first stage of initiation of these therapies, which would correspond to the first half of the twentieth century; a second stage of expansion of the group therapies in psychoses, which took place from the 1950s to the 1990s; and third stage of consolidation of these therapies during the last 30 years. The group psychotherapy of the psychoses has a century of history. It is practised worldwide, in institutions and organisations of all types, in many care programmes, with many modalities and approaches, and in a very heterogeneous wide range of persons with psychotic experiences, biographic evolutions and distinct characteristics.
