"While a body of professional literature attests to the central role of mutual aid in social work practice with groups, what has been lacking is a single source that links the description of mutual aid with practice prescriptions. This book does just that. This updated edition of the pathbreaking original contains four entirely new chapters that address single-session groups, short-term groups, open-ended groups, and very large groups. In addition, this book will help you to better understand and make use of mutual-aid perspectives on pregroup planning, early group goals and norms, the significance of time and place, and the role of the group worker, individual problem solving, and authority, conflict, and evaluation."--BOOK JACKET.
