Advances in Group Therapy Trauma Treatment contains compelling theoretical, clinical, and research advances in group trauma therapy by leading experts in the field. This timely book includes short-term integrated and long-term psychodynamic group therapy models from several theoretical perspectives, with informative clinical illustrations in each chapter describing how to foster co-regulation of affect, treat disturbances in attachment, and address dissociation, shame, primitive defenses, and enactments associated with PTSD, complex PTSD, and sexual abuse. Interventions to address the harm and loss of safety following mass trauma that are often mirrored in large and small psychotherapy groups are described. Unique to this volume is the role of diversity, the necessary adaptations of group therapy models to different cultures, and the relationship of trauma to structural and systemic racism, hate, and bigotry. Finally, leadership considerations such as training, ethical guidelines, supervision, pre-group preparation, and self-care for group therapists will be enumerated. Integrating well-established group theory and techniques with new practice and research findings, this book is indispensable to mental health professionals who treat traumatized individuals.
