Military Sexual Trauma Statistics

What does Military Sexual Trauma look like when you translate it into outcomes, costs, and missed care? From RAND’s 1.4 million population weighted lifetime prevalence estimate to VA data showing MST is a major pathway to PTSD and that PTSD related mental health care is closely tied to MST history, these statistics connect exposure to reporting barriers, treatment uptake, and higher utilization and costs.

A RAND modeling study estimates a 1.4 million population weighted lifetime prevalence of Military Sexual Trauma among women in the U.S. military cohort, yet many survivors still do not report what happened. From 1 in 5 women Veterans in a 2019 VA survey to 30 percent of women Veterans reporting MST related concerns in VA program materials, the path from exposure to care is anything but straightforward. These figures also connect to major downstream outcomes, including PTSD pathways and higher utilization of VA mental health services, which is why the details behind reporting and treatment matter.
