Principles of Trauma Therapy, Third Edition by John Briere and Catherine Scott is a thorough and quite useful book. The cognitive-behavioral, relational, affect regulation, mindfulness, and psychopharmacologic approaches to the “real world” treatment of acute and chronic posttraumatic states are creatively synthesized in this best-selling book. This book provides a practical guide for front-line clinicians, private practice practitioners, and graduate students of public mental health. It is based on empirically supported trauma treatment procedures and tailored to the intricacies of real clinical practice.
