“…In discussing the group treatment of schizophrenics, Leopold (1976) suggests the use of interrelated groups that are graded and structured according to degree of patient pathology.

To date, however, no one has examined what effect various occupational therapy group structures have on the quality and quantity of social interaction that occurs in such groups.…”
