Best text about an essential therapeutic method
Group therapy is, in my opinion, a criminally neglected and underrated tool in the toolset of psychotherapy and medicine. Group reveals our attachment style and communication patterns with a clarity, efficiency, and force that no other form of psychological intervention can match -- every person on the planet should spend some time in a group dealing with his or her mental and/or emotional issues. The world would be a better place.
Irv Yalom probably knows more about group than any other person, and this guidebook is essential to anybody wanting to understand the form. Yalom explains group thoroughly, in an understandable but frequently profound manner. The main drawback is that the book may even be overly comprehensive, and its length is likely to intimidate non-professionals, which is a shame because the benefits of group need wider dissemination.

Yalom's Group Therapy "Bible" continues to be the gold standard in group work.
I have used Yalom's Group Therapy book since my doctoral training in the early 90's. His work is timeless and it is clear he is an individual who understands the heart and the soul of our work. I created and facilitate a 18 - 20 week Relationship Academy which is part didactic and part experiential. It is amazing to see the group dynamics play out as expected based on Yalom's work. I will often read from this text in the morning, so that my mind is prepared for the day. It often changes my perspective and opens my eyes to considering different interpretations of behavior and it encourages me to silence myself and allow the "process" to work. How very rewarding this is! I don't see how serious group work can be done without Yalom's influence. Thank you so much for the updated text.

Needs to be updated
Format: Hardcover
Excellent book, but now that it is 2019, it needs to be updated to reflect the current health care system. This book details average inpatient hospitalization stays as 10-90 days. The current average length of stay at an inpatient hospital is 3-15 days. So a lot of the information about how to run groups was not as applicable now - in the book, it assumed patients would be together in groups for weeks, but the reality is that sometimes patients are only together for a day or two.

Yalom Still Rules
Yalom is as relevant today as ever. Writing with art for science, Yalom offers insights and wisdom for clinical group practice that have changed the way I approach my whole life. If you have the luck to read this as an assigned text, you may be relieved by his novelistic approach and his integration of existential philosophy. If you are looking for the deep dive, he’s your guy.
