[Therapeutic factors in psychoanalytic-interactional and depth psychology founded group therapy: an empirical study]

Depth psychology based and psychoanalytic-interactional group therapy were compared with respect to their therapeutic factors. The comparison was performed in patient groups by using a questionnaire asking for the occurrence and helpfulness of specific behaviour of the therapist and of experiences in the group. About 200 questionnaires for each method were analyzed. It could be shown that (1) discrimination between the methods was more marked concerning therapist's behaviour than experiences with the other group members, (2) that the obtained unspecific factors correspond to results in the literature on group and individual therapy and (3) that those items about the therapists behaviour claimed to be specific for each method did not discriminate these methods in the expected direction.
