This book spotlights the unique contribution of the Journal for Specialists in Group Work to the social justice literature, and of group work to a social justice agenda. Although the term social justice may be relatively new in the counseling and psychology literature, the underlying values - attention to inequities, advocacy, and empowerment strategies for members of marginalized and oppressed populations - are not new in group work. Group leaders have been attending to these concerns all along, and group work itself is an ideal venue for the realization of social justice concerns. However, until now there has been a limited amount of scholarship on group work with a stated focus on social justice. This groundbreaking book emphasizes action through a practical approach, featuring research and case studies of social justice group work in community and school settings.　Chapters highlight how group workers infuse social justice consciousness into their work, address social justice issues, and implement social justice practice. Authors review the history, practice, and future opportunities for social justice advocacy within group modalities. They also address guidelines for the training and supervision of practitioners engaging in social justice group work. This book was published as a special issue of the Journal for Specialists in Group Work.
