Group-based interventions are the most common modality for treating adult sexual abusers and are used in most structured programs. Th¬is innovative training will focus on improving attendee’s effectiveness as group facilitators for sexual abusers by learning practical skills that can be used in day-to-day clinical work. Together we will review the essential elements of group agreement and structure, how to facilitate member-to-member interaction vs. individual focus, how to nurture the group’s emotional climate, and key therapeutic factors. Using the group process to address attachment issues and the assessment of group process using available instruments will also be reviewed. Throughout the training, experimental exercises will be used to illustrate key principles and explore instrument use. This training is relevant to both practitioners who provider services to adolescents as well as adult perpetrators of sexual abuse.
