Their purpose is supposedly to help people to become "more sensitive" to themselves and to others. T-groups have been sponsored by public and private agencies, by universities, by private industry, and by others. Although a great deal of money is frequently involved in running one of these programs, there has been relatively little research into their value or their hazards.Gottschalk1 has described a group in which he participated in which six of the 11 people participating had psychopathological reactions to the group. In another T-group he observed, five of ten participants had "acute pathological emotional responses, including one frank psychotic reaction and one borderline acute psychotic withdrawal reaction."1 Jaffe and Scherl,2 reporting in a recent issue of the Archives
