The construct of social privilege is ubiquitous within the multicultural and social justice literature. However, the group work literature has yet to integrate the construct into group theory, processes, and training. In this article, we review the group literature on multicultural and diversity issues. Also, we examine the multicultural and social justice literature for an operational definition of social privilege. Finally, we make an argument for the impact of social privilege on group work and for the necessity of integrating social justice competencies into group work.
