Symbolic and concrete functioning of a psychotic within a group is studied. It was found that such patients benefit from group therapy. The authors believe, contrary to the opinions of other group therapists that are reviewed, that interpretation of transference, countertransference, and id analysis can be used as in a personal analysis. The authors review the literature and find that psychoanalytic concepts are dissociated from the material handled in the group. This practice tends to disrupt the group. They suggest that their more classic psychoanalytic approach could be applied to community psychiatry in general.
