How can groups effectively meet the needs of humans in areas as diverse as aid, responsibility, action, healing, learning and acceptance? This edited volume aims to address these issues and provide ways to extend the current reach and quality of social work with groups. Based on a selection of papers from the 24th Annual International Symposium of the Association for the Advancement of Social Work with Groups (AASWG) the chosen chapters embody the strength and diversity of the Symposium, encouraging and encourage readers to 'Think Group'. Chapters address the future challenges faced in social work with groups, including issues in teaching group work, holistic thinking about groups, team-building, staff development programs and university-agency collaborations to strength group work practice. There are chapters focusing on how mutual aid groups support trauma recovery, including one with firemen addressing the aftermath of the 9/11 disaster, as well as chapters that examine group work's place in community development, challenging social isolation, mask making as a medium for growth, and special issues in addressing concerns of children and youth. This book will be of interest to researchers, professionals and students in social work and human service fields.
