With ongoing war in Iraq, the incidence of posttraumatic stress disorder (PTSD) in combat veterans is increasing. Creation, implementation, and testing of new and innovative interventions are needed to provide additional options for enhancing the mental health of those with PTSD. Surveys indicate that veterans are interested in complementary approaches to health care. The purpose of this study is to determine the efficacy of the Mantram Repetition Program (MRP) delivered as a brief, 6-week, complementary and portable intervention. It includes frequent, silent repetitions of a mantram (mantra), a word or phrase with spiritual associations, to manage PTSD symptoms and improve quality of life military veterans with trauma.
