'Therapist's Guide to Post-Traumatic Stress Disorder: Prolonged Exposure Therapy, 2nd Edition' and 'Post-Traumatic Stress Disorder Workbook: Prolonged Exposure Therapy, 2nd Edition' are a set of treatment books that contain the most scientific methods for treating post-traumatic stress disorder (PTSD), the psychological damage that survivors experience after experiencing sexual violence, school violence, crime, war, or disaster.
Post-traumatic stress disorder is accompanied by symptoms such as 're-experiencing' the traumatic event, such as repetitive intrusive thoughts or nightmares, 'avoidance' of people, places, situations, and objects related to the trauma, and 'hypervigilance', which causes excessive vigilance and anxiety. These symptoms not only cause psychological distress, but also lower the quality of life, cause problems with family and interpersonal relationships, and ultimately lead to economic loss.
Students who have been victims of sexual assault or child abuse, veterans, prisoners of war, victims of traffic accidents or disasters, or who have experienced school violence, or “bullying,” which is a growing social issue these days, are also more likely to suffer from post-traumatic stress disorder (PTSD) in the future.
Research suggests that between 40 and 90 percent of people will experience at least one traumatic event in their lifetime.
In most cases, the stress response caused by trauma will disappear after several months with the warm care of family or friends, but in about 20% of cases, the symptoms will worsen and develop into post-traumatic stress disorder.

Prolonged Exposure Therapy (PE) was developed by Edna B. of the University of Pennsylvania.
Edna B.
Developed by Dr. Foa, Ph.D., it is a scientifically proven psychotherapy technique that can very effectively treat various PTSD symptoms such as sexual violence, domestic violence, disasters, accidents, crimes, and torture in a short period of time.
Prolonged exposure therapy (PE) has been adopted as a PTSD treatment technique certified by the Substance Abuse and Mental Health Services Administration (SAMHSA) of the U.S. Department of Health and Human Services and has been widely recognized for its effectiveness. Many victims around the world are overcoming post-traumatic stress disorder through PE.

The '12-Week Leap' set for treating post-traumatic stress disorder was translated and published to enable clinicians who are pioneering the use of prolonged exposure psychotherapy for PTSD treatment in clinical settings to interact with survivors suffering from PTSD.
This set consists of the 『12-Week Leap for Post-Traumatic Stress Disorder, Subtitle - Prolonged Exposure Therapy (PE) Workbook for Healing Sexual Violence and Trauma Victims』, which clients use as a workbook while undergoing Prolonged Exposure Therapy with a skilled professional, and the therapist guidebook 『12-Week Leap for Post-Traumatic Stress Disorder, Subtitle - Prolonged Exposure Therapy (PE) Therapist's Guide』.
This manual and workbook provide step-by-step, detailed procedures for assessing, treating, and diagnosing individual problems and specific issues.
We also provide a wealth of additional resources to help clinicians directly apply these procedures in their own clinical settings.
The workbook is designed to be easily understood by clients, their families, and their guardians, so it will serve as a guide to help those around them better understand the pain clients experience.
The therapist's guide is also designed to maximize the effectiveness of treatment by providing professional content and a three-dimensional view of various situations that may arise in treatment situations.

Over the past 30 years since its development, the sustained exposure therapy program presented in this treatment book has been applied worldwide to diverse groups, including female survivors of sexual violence, child survivors of sexual violence, victims of school violence, veterans of war, victims of crime, victims of torture, and victims of disasters and traffic accidents, and many clients have been able to live new lives.
In Korea, too, over the past 15 years, many survivors have overcome post-traumatic stress disorder through prolonged exposure therapy (PE).


This revised edition is designed to be applicable to a wider range of trauma survivors. The authors, pioneers in PTSD treatment, training, and research, have conducted extensive PTSD-related research since the first edition was published, and their findings have been incorporated into this revised edition. They have developed the underlying theory of PE, incorporated modifications for clients and veterans with more complex symptoms, and incorporated research-based evidence for individualized treatment.
This therapist guide and workbook set accurately and rigorously describes the core elements of the prolonged exposure therapy program, providing therapists with guidance on how to apply it and when and how to tailor it to their clients.
