A married man in group therapy for two and a half years made little progress because of his transference wish to defeat the therapist, while in marriage he showed his transferred hostility to his mother and sister. When his wife was invited to the group as a visitor, the Oedipal situation was recreated for him, since he could no longer separate the parents by keeping the father in the therapeutic group, the mother at home. A new positive relationship was established as the father-leader's approval was sought. Later the patient was able to work through his hostility to his mother who he felt had deserted him by dying.
