Effects of an Alternative Treatment for Military Sexual Trauma on PTSD Symptoms, Neurosteroids and Brain Function

Effects of an Alternative Treatment for Military Sexual Trauma on PTSD Symptoms, Neurosteroids and Brain Function

Our specific aims are:

1. To examine the efficacy of GIFT in improving MST-related clinical outcomes in women veterans
2. To examine the effects of GIFT on fronto-limbic brain function and
3. To examine the effects of GIFT on levels of neuroactive steroid associated with PTSD.

Guided imagery is a complementary and alternative treatment (CAM) modality. This directed meditation technique uses healing imagery to promote recovery in a variety of illnesses, including cancer, heart disease and, more recently, posttraumatic stress disorder (PTSD). PTSD is a severe and disabling anxiety disorder. It is among the most common mental disorders, affecting 10% of women in the United States during their lifetime. Sexual assault is the most common cause of PTSD. Similarly, military sexual trauma (MST) is disturbingly common among women in the armed forces. At least 20% of women veterans using VA services report a history of sexual assault. Unfortunately, high rates of MST-related PTSD are anticipated among women currently deployed to Iraq and Afghanistan.

To address this issue, we will evaluate a guided imagery intervention for women veterans who have MST-related PTSD. We will evaluate the efficacy of Guided Imagery for Trauma (GIFT) in decreasing PTSD symptoms. Using brain-imaging techniques, this research will examine the effects of GIFT on brain function in the areas associated with PTSD. We will also examine the effects of GIFT on neurosteroids, which are candidate modulators of PTSD symptoms, and may also represent novel targets for therapeutic intervention.
