This revised and updated Third Edition continues to correlate group work techniques with occupational therapy theory and practice. It describes a practical approach to treating a wide range of developmental, physical, mental and environmental disorders. This authoritative text leads readers through the logic of planning, implementing, and evaluating a functional group. New features include: a theoretical base, containing up-to-date research findings that validate Howe and Schwartzberg's group model in professional practice; case material reflecting current and future-oriented theories and practices; new boxes, sidebars, key terms, clarification checkpoints, review questions, and other visual materials; and photographs depicting current practice.
