 Military sexual trauma MST is a significant womens mental health issue. There is a crucial need for effective therapies for MST-related posttraumatic stress disorder PTSD that are well-tolerated and can be flexibly administered in a variety of treatment settings. Guided imagery is a novel, transportable intervention technique that meets these requirements and warrants research in PTSD. The proposed study will be a randomized controlled trial of the Guided Imagery for Trauma GIFT intervention for women veterans with MST-related PTSD. This minimal contact intervention is designed to increase coping, affect management and relaxation skills, and to fostering more positive images and beliefs associated with surviving trauma. The feasibility and tolerability of GIFT have already been demonstrated in an open-label pilot of 15 women veterans with MST-related PTSD, with very promising initial results.
