is a scholarly work. This book is written as a guide to assist the reader in understanding and developing evidence-based group work (EBGW). This highly organized guide emphasizes and describes the process of evidencebased practice (EBP) evolving to EBGW. This would be an excellent textbook for an undergraduate-or graduate-level academic course on group therapy. Psychologists, psychiatrists, social workers, and other counselors would perhaps be wise to become familiar with this work. This outstanding book is also practical. Each chapter is filled with very useful information on the approach of EBGW. Clinicians and researchers would benefit from learning and using this material in their group work. As an invaluable resource, it put forth a framework for current and future practice in group work. Important resources fill the book's chapters with current facts, Web site information, and an extensive review of the process of evaluating research studies. The importance of best evidence, application in practice, and evaluation are essential to EBGW, and this provides the conceptual framework for the entire book. The author presents a strong perspective for creating best practices for EBGW. The content is constructed into three parts and a total of six chapters. Part I, Chapter 1, reviews six assumptions of EBGW. It then focuses on the historical origins and development of evidence-based medicine and EBP. In Part II, Chapters 2, 3, 4, and 5 describe in great detail the four stages necessary to operationalize EBGW. The four stages are: formulate an answerable question; search for evidence; undertake a critical review of the evidence; and apply the evidence with judgment and skill and evaluate outcomes. Part III, Chapter 6, is entirely devoted to the dissemination of EBGW in research, clinical practice, and education. The transrelational research approach described in this chapter explores how a planned, system-wide collaboration between education, research, and clinical practice could be achieved. Such an organizational context supportive of EBGW would use practice-relevant research readily available to group workers, with ongoing education and consultation to all.
