Book excerpt: This book provides group therapists and counselors with the necessary knowledge and help to develop their skills in effectively conducting online groups. Group therapy represents the most efficient utilization of the scarce resource of mental health interventions. Online settings dramatically increase the dissemination of this approach. This book identifies the diverse challenges and suggests solutions in remote group therapy for specific therapeutic approaches such as psychodynamic, relational, psychodrama, CBT, ACT, and group supervision. The contributing authors explore specific issues that anyone who conducts groups online should be aware of. Using a group therapy lens, this book develops further the ideas and areas explored in the authors’ previous books Theory and Practice of Online Therapy and Advances in Online Therapy.
