DoD Safe Helpline: 1-877-995-5247What is Military Sexual Trauma (MST)?

 Military sexual trauma (MST) refers to experiences of sexual assault or repeated, threatening sexual harassment that a Veteran experienced during his/her military service.  The Department of Veterans Affairs (VA) uses the definition given by Federal Law (Title 38 U.S. Code 1720D) stating MSAT as “trauma, which in the judgment of a VA mental health professional, resulted from a physical assault of a sexual nature, battery of a sexual nature, or sexual harassment which occurred while the Veteran was serving on active duty or active duty for training.” Sexual harassment is defined as “repeated verbal or physical contact of a sexual nature which is threatening in character.”

MST includes any sexual activity where a Veteran/Servicemember is/was involved against his/her will. For example:

  • He or she may have been pressured into sexual activities
  • He or she  may have been unable to consent to sexual activities
  • He or she may have been physically forced into sexual activities
  • Other MST experiences include unwanted sexual touching or grabbing; threatening, offensive remarks about a person’s body or sexual activities; and threatening and unwelcome sexual advances.

The identity or characteristics of the perpetrator, whether the Veteran/Servicemember was on or off duty at the time, and whether he or she was on or off base at the time do not matter. If these experiences occurred while an individual was on active duty or active duty for training, they are considered by VA to be MST.

Facts About MST

  • According to the DoD, an estimated 19,300 sexual assaults occurred in the military in 2010; 13.5% of total survivors reported assault – 10,700 vicitims were men and 8,600 were women
  • 1 in 5 women and 1 in 100 men responded “yes” when screened for MST by VA providers
  • According to the VA, MST is an experience, not a diagnosis, and Veterans’ current treatment needs will vary
  • Rape, sexual assault, and sexual harassment are the leading causes of post-traumatic stress disorder (PTSD) among women veterans, while combat trauma is still the leading cause of PTSD among men
