The author shows how object relations group therapy focuses on primitive defense mechanisms that shape the group-entity image or "basic assumptions group." Such primitive defense mechanisms as splitting, projective identification, omnipotent denial, projection, and introjection are the mental resources to protect the endangered self and the threatened objects from the fantasized imminent destruction. Object relations group psychotherapy addresses those defenses and the underlying psychotic anxieties, offering members opportunities to search for other ways to respond to their primitive fears. The author introduces two extensive clinical vignettes to illustrate how object relations group methods are different from other group-centered psychoanalytic techniques. He concludes by commenting on future theoretical refinements and on the problems in the professional practice of this modality.
