This paper describes clinically important aspects of diagnosis and int
ervention in groups, refering to the Gottingen model of psychoanalytic
group therapy and concentrating on norms and psychosocial compromise
formations that regulate the group process, as well as on ways to deal
with them therapeutically. A group interacts with the therapist as a
professional and as a person. Ways of finding one's way through the co
mplexities of a group process are described, with special reference to
countertransference analysis.
