The discussions focus on group work in prisons and probation hostels and day centers, as well as community- based group work with different types of offenders, and explores the implications and issue for social workers and probation personnel, including issues of consent. The papers note that group work is a generic term that covers a range of models, purposes, and practice ideologies. Social skills groups and offending behavior groups are two of the most common groups; each tends to be offered as a structured, short-term program for promoting individual change. Individual papers survey existing forms of group work, the philosophies involved, self-directive group work in a youth custody center, the evolution of groups in a day center for offenders, a centralized approach to group work in an intensive probation program, a feminist model of group work, a Miskin model of group work with female offenders, group work with violent offenders, and principles of group work with male sex offenders.
