Robin Shapiro in Therapeutic Interventions in Ego States, published by Kathexis Editions, successfully attempts and approaches a dynamic and flexible trauma therapy focusing on ego states. Her rich and extensive therapeutic experience allows her to articulate in a simple and understandable manner what she has learned and what has led her to be such a successful therapist. This book is an essential guide for the modern psychotherapist. Additionally, the introduction of this book presents for the first time the concepts of this specific therapy in the Greek language. The author initially introduces the reader to ego states, defining the concepts she will address. She then discusses how therapists can approach the positive aspects of the self. Furthermore, she deals with specific interventions such as trauma treatment, challenges in relationships, personality disorders. Additionally, she addresses the treatment of suicidal individuals and the eradication of dysfunctional ingrained beliefs that we all have. These beliefs are usually due to cultural and familial influences.
