Previously, articles on and contributions to the history of psychotherapy proceeded on the assumption that the most essential sources were to be found in Anglo-Saxon and German literature. Developments in other civilizations were usually treated as undeserving of consideration. It is important to note that a large amount of specialized literature on psychotherapy has been published in the Soviet Union, and this shows that a great importance is attached in that country to the treatment of nervous and mental disorders by psychological methods. A review of the writings of S. S. Korsakov and V. M. Bekhterev shows that the essential principles of group psychotherapy had been recognized by those authors already in the late nineteenth and early twentieth centuries, respectively. Results achieved by Makarenko appear valuable in the light of what we know today. The method of "collective psychotherapy", which was first described by Libch, is discussed in detail. This method is being widely used in the Soviet Union. The concern of this paper is to describe developments which have not so far been covered in our literature, thus attempting to make an addition to psychotherapeutic activity in this country.
