Book excerpt: An insider perspective from a 'cop doc on the job,' this book is the first of its kind written in response to a need for a specialized guide for clinicians that operationally defines and responsibly treats what Dan Rudofossi terms Police and Public Safety Complex PTSD. In reading this book, you are led through an understanding of how to work with police officers who experience cumulative loss in trauma. "Doc Dan" initiates you into an original cultural competence of how and why his theory works in practice. You will leave the journey with a practical sense of how the ecological context and ethological motivation are part of the psychological presentation of almost all officers suffering from complex trauma and loss.This guide is crucial reading, original in its breadth and scope of perspective on how to intervene with the traumatized officer. Toward that end, Rudofossi presents his Eco-Ethological Existential Analysis of Police and Public Safety Complex Post Traumatic Stress Disorder. Emotive, affective, cognitive, behavioral, and existential ranges of expression of trauma are vast, diverse, and often intense in police officers. This book delivers applied theory with clinical examples, including practical interventions for the clinician and handouts for the officer-patient. The clinician will be assisted in encountering officers' existential suffering from the edge of despair to the precipice of meaning. The guide is at once stimulating, exciting, and very serious in its potential for clinical interventions.
