The purpose of this study was to introduce a PTSD patient who experienced significant effects of mindfulness meditation and Ii-Gyeung-Byun-Qi therapy. Our psychotherapy was executed five times a week for the 14-year-old male patient who attended middle school and was diagnosed by DSM-IV Diagnostic Criteria for PTSD, and then the MMPI-A was evaluated to determine the effects after 3 months. The results showed normal profiles of MMPI-A validity scales and Clinical Scales profile after his treatment, positive changes in content scales, and significant decreases of PSYC (psychoticism) and NEGE (negative emotionality) in PSY-5 scales. This study made through a case report on the treated psychotherapy for PTSD by the applications of modern psychological techniques in the Korean psychotherapy. We expected that this case report will have a role in development of standardized psychotherapy programs for PTSD.
