“…Although these structural elements are particularly crucial to the agenda model that Yalom (1983) recommended for high-functioning inpatients, most studies have examined the effects of structure on the group behaviors of low-functioning inpatients. A number of studies on inpatient samples (e.g., Goldstein, 1971;Gruen, 1977;Jensen & McGrew, 1974) show that particularly with disturbed patients, a high level of structure promotes positive interactions among members. Other studies (e.g., Bednar, Melnick, & Kaul, 1974;Kinder & Kilmann, 1976) suggest that a high level of structure is most appropriate for a group in the earliest phase of development, in which an open-ended inpatient group with rapidly changing membership is likely to reside most of the time.…”
