The Portuguese groupanalytic movement began in 1956 through the efforts of Professor Doutor Eduardo Luis Cortesão, in the then Portuguese Society of Neurology and Psychiatry.In 1958 a groupanalytic study group was set up which, five years later, was constituted as a Scientific Society, a department within the Portuguese Society of Neurology and Psychiatry.

In 1963 the Department of Groupanalysis was officially established.
In 1981 the Portuguese Groupanalytic Society was constituted.
Eduardo Luis Cortesão undertook his training in groupanalysis in London with Foulkes. With this background of the British school of groupanalysis, he returned to Portugal where he developed the theory and practice of this therapeutic process thereby paving the way for the setting up of a vigorous Portuguese psychoanalytic school, with its own specific characteristics now recognized within the group analytic therapies of Europe and worldwide.

The activities of the Portuguese Groupanalytic Society include the preparation and training of groupanalysts. (An index of these can be found on this website) a bibliography, the publication of a journal and an on-line journal as well as news, reports and comments on a variety of activities, scientific events, research etc.

The PGS has played a decisive role in the establishment of groupanalytic therapeutic practice in Portuguese hospitals, namely, the hospitals of Santa Maria, Miguel Bombarda, São Francisco Xavier and Amadora-Sintra, and the Hospital Militar Principal, as well as in reception centres for drug dependents and detention centres. The PGS has also contributed, to the training of health professionals (doctors, psychologists, medical students, nursing staff, social assistants and occupational therapists).
Of prime concern for PGS has been to inculcate rigorous standards in training and professional practice in groupanalysis, the provision of training for groupanalysts, the maintaining of contacts with international peer organisations, thus ensuring that advances and research into the theory and practice of groupanalysis are publicized and encouraged.
