Excellent book for students trying to grasp PTSD
As a professor teaching post traumatic stress reaction to graduate and undergraduate students, I was looking for a book that hit the basics along with some key pieces regarding assessment, diagnostic criteria, and examples that highlighted some of the subtleties associated with complex trauma. This book is well organized and not too overwhelming for people new and beginning the field and a nice refresher for seasoned clinicians. Easy to read, clearly outlined to build upon each subject, I found it both a solid read, affordable, and made it a required read for my course. Please note that I purchased this book way back October 12, 2013 but only now getting to put my thoughts in writing.

Great interventions and Trauma Theory
Format: Paperback
This a great book if you work with victims of trauma and want to understand how different types of trauma can present and what interventions can be used (i.e urge surfing, cognitive restructuring, focus breathing, etc.). It also include a section about medications and what to address first in treatment. I think it’s great for new clinicians who may be looking for interventions to add to their clinical toolbox.
