Military Sexual Trauma and Mental Health: Understanding the Impact of MST

Jump to Section

Military sexual trauma can leave wounds that are difficult to explain, especially when the trauma happened in an environment built around trust, order, loyalty, and service. For many survivors, the pain is not only tied to the sexual assault or harassment itself. It is also tied to betrayal, silence, fear, retaliation, or the feeling that the system they served did not protect them.

Military sexual trauma, often shortened to MST, refers to sexual assault or threatening sexual harassment that happens during military service. MST can affect veterans and service members of any gender, age, rank, branch, background, or identity. It can happen during training, deployment, active duty, reserve service, or other military-related settings.

Some survivors know right away that what happened changed them. Others push through for years before symptoms become harder to ignore. Many people continue working, raising families, managing responsibilities, and appearing strong while privately struggling with PTSD, depression, anxiety, shame, anger, sleep problems, emotional numbness, or difficulty trusting others.

Military sexual trauma is not a weakness. It is not something a person should have been able to “just get over.” It is a traumatic experience that can affect the brain, body, nervous system, relationships, self-worth, and ability to feel safe.

At Montare Behavioral Health, we understand that trauma recovery requires more than general encouragement. Survivors need compassionate, structured, trauma-informed care that respects their story, their pace, and their right to feel safe again.

What Is Military Sexual Trauma?

Military sexual trauma is a term used by the Department of Veterans Affairs to describe sexual assault or threatening sexual harassment experienced during military service. MST can include physical assault, coercion, threats, intimidation, repeated sexual comments, unwanted touching, forced sexual activity, or pressure for sexual contact.

MST may include experiences such as:

  • Being touched sexually without consent
  • Being pressured or forced into sexual activity
  • Being threatened after refusing sexual contact
  • Being sexually harassed by a peer, supervisor, superior officer, or subordinate
  • Being targeted with repeated sexual comments or intimidation
  • Being assaulted while asleep, intoxicated, drugged, unconscious, or unable to consent
  • Being told not to report what happened
  • Facing retaliation, isolation, blame, or career consequences after speaking up

MST can happen to women, men, and LGBTQIA+ service members. Although women veterans are often discussed in relation to military sexual trauma, men can also be survivors. Male survivors may face added stigma, silence, or pressure to minimize what happened because of expectations around masculinity, strength, or military identity.

The truth is that sexual trauma is serious no matter who experiences it. A person’s gender, rank, age, or service history does not make the trauma less real.

Why Military Sexual Trauma Can Be So Difficult to Process

MST can be especially complicated because it often happens within a system where the survivor may depend on others for housing, medical care, work assignments, protection, career advancement, and daily structure. A survivor may not be able to simply leave the environment or avoid the person who harmed them.

Some survivors are forced to keep working near the person who assaulted or harassed them. Others may be discouraged from reporting. Some may feel pressure to protect the unit, the mission, or the reputation of leadership. Others may report the trauma and feel punished, doubted, ignored, or retraumatized by the response.

This can create layers of trauma. The original violation is painful enough. But the aftermath can add betrayal, powerlessness, shame, anger, and distrust.

A survivor may struggle with questions like:

  • Why did this happen to me?
  • Why did I freeze?
  • Why did I not fight back?
  • Why did no one protect me?
  • Why was I blamed?
  • Why did I stay silent?
  • Why did reporting make things worse?
  • Why do I still feel unsafe years later?

These questions are common after trauma. They do not mean the survivor did anything wrong. They often reflect the mind’s attempt to make sense of an experience that was frightening, violating, and unfair.

Mental Health Effects of Military Sexual Trauma

Military sexual trauma can affect mental health in many ways. Some people develop symptoms immediately. Others experience delayed symptoms that appear months or years later. Symptoms may become stronger during stress, relationship changes, grief, pregnancy or postpartum changes, retirement from service, medical issues, or other reminders of the trauma.

Common mental health effects of MST may include:

  • Post-traumatic stress disorder
  • Depression
  • Anxiety
  • Panic attacks
  • Sleep problems or nightmares
  • Emotional numbness
  • Shame, guilt, or self-blame
  • Anger or irritability
  • Difficulty trusting others
  • Relationship struggles
  • Fear of intimacy
  • Dissociation or feeling disconnected from the body
  • Hypervigilance
  • Avoidance of reminders
  • Low self-worth
  • Suicidal thoughts or hopelessness

MST can also affect the body. Trauma is not only stored as a memory. It can influence the nervous system, stress response, sleep patterns, pain sensitivity, and the way a person reacts to perceived danger.

A survivor may feel tense, startled, frozen, detached, or on edge even when they are physically safe. They may avoid certain places, people, sounds, smells, medical settings, authority figures, or conversations because those reminders activate the body’s alarm system.

These reactions are not signs of weakness. They are trauma responses. The nervous system is trying to protect the person from being hurt again, even when the threat is no longer present.

Military Sexual Trauma and PTSD

Post-traumatic stress disorder can develop after a person experiences or witnesses trauma. MST can contribute to PTSD because it often involves fear, coercion, helplessness, betrayal, bodily violation, and loss of control.

PTSD related to MST may include:

  • Intrusive memories
  • Nightmares
  • Flashbacks
  • Emotional distress when reminded of the trauma
  • Avoidance of people, places, or topics connected to the trauma
  • Negative beliefs about oneself or others
  • Shame or self-blame
  • Feeling distant from others
  • Irritability or anger
  • Trouble sleeping
  • Feeling constantly alert or unsafe

Some survivors do not experience PTSD in the way they expected. They may not have clear flashbacks. Instead, they may feel emotionally flooded, numb, suspicious, easily triggered, or unable to relax. They may feel like their body reacts before their mind understands why.

Trauma treatment can help survivors recognize these responses and begin separating the past from the present. The goal is not to erase the memory. The goal is to reduce the power the trauma has over daily life.

Military Sexual Trauma, Depression, and Shame

Depression after MST can feel heavy, isolating, and hard to explain. Some survivors feel like they lost the person they used to be. Others feel disconnected from their service, their body, their relationships, or their future.

Depression may show up as sadness, exhaustion, low motivation, hopelessness, irritability, emotional numbness, difficulty concentrating, or loss of interest in life. Survivors may also carry intense shame, even when they know logically that the trauma was not their fault.

Shame can tell a person:

  • I should have stopped it.
  • I should have reported it.
  • I should have handled it better.
  • I am weak.
  • I am damaged.
  • No one will understand.
  • I cannot trust anyone.

These thoughts are painful, but they are not the truth. Shame often grows when trauma is kept secret or when survivors are blamed, dismissed, or unsupported. Healing begins when survivors are met with respect instead of judgment.

A trauma-informed treatment setting can help survivors separate what happened to them from who they are. MST may be part of a person’s story, but it does not define their worth.

Military Sexual Trauma and Anxiety

Anxiety after MST can feel like living with an internal alarm that will not shut off. A survivor may feel restless, tense, overwhelmed, guarded, or unable to relax. They may have racing thoughts, panic attacks, nausea, chest tightness, difficulty sleeping, or a constant sense that something bad is about to happen.

Anxiety can also affect relationships. A survivor may want closeness but fear vulnerability. They may struggle to trust others, set boundaries, accept support, or feel comfortable with intimacy. They may pull away from people they love because their nervous system has learned that closeness can feel dangerous.

This does not mean the survivor is broken. It means their system learned to survive. Treatment can help the person slowly rebuild a sense of safety, choice, and connection.

Why Some MST Survivors Do Not Ask for Help Right Away

Many survivors of military sexual trauma wait years before telling anyone what happened. Some never report it. Some minimize it. Others only begin to understand the impact after their symptoms become harder to manage.

A survivor may delay getting help because they believe:

  • Other people had it worse
  • It happened too long ago
  • They should be over it by now
  • They will not be believed
  • They will be judged
  • They will have to share every detail
  • Treatment will make them feel worse
  • No one will understand the military context
  • Their symptoms are just part of who they are now

These fears are understandable. MST often involves both personal trauma and institutional betrayal. It can take time before a survivor feels safe enough to talk about what happened.

Healing does not have an expiration date. Whether the trauma happened recently or decades ago, support can still help.

Military Sexual Trauma and VA Disability

Some veterans who experienced military sexual trauma may be eligible for VA disability compensation if MST caused or worsened a physical or mental health condition. MST itself is not a diagnosis. Instead, the VA looks at whether the trauma is connected to a current condition such as PTSD, depression, anxiety, panic disorder, sleep problems, or other trauma-related symptoms.

A veteran does not need to have reported the trauma when it happened in order to file a claim. Many MST survivors never reported the event because they feared retaliation, were not believed, felt unsafe, or did not know where to turn. Because of this, the VA may consider different types of supporting evidence, including medical records, counseling records, behavioral changes, requests for transfer, changes in work performance, statements from people the veteran told, or other signs that something changed after the trauma.

VA disability claims can feel overwhelming, especially for survivors who already feel exhausted by having to explain or prove what happened. A trauma-informed treatment team can support the clinical side of healing by helping identify symptoms, document mental health needs, and provide care for conditions connected to MST. For help with filing a claim, veterans can contact the VA, a Veterans Service Organization, or an accredited VA claims representative.

Seeking treatment is not only about a disability claim. It is about safety, stability, and support for the ways MST may still be affecting daily life.

MST Disability Claim Approval and Denial Statistics

Available VA data shows that MST-related claim approval rates have improved over time. According to VA reporting, the grant rate for conditions related to military sexual trauma was 50% in 2015, 68% in 2020, and 72% in 2021. Put another way, the estimated denial rate fell from about 50% in 2015 to about 28% in 2021.

For comparison, the VA reported that its overall claim grant rate was 64.6% during fiscal year 2024, which means the overall denial rate was about 35.4% for that reporting period. This is not a perfect one-to-one comparison because the MST data and overall disability claim data come from different years and different reporting categories. Still, it gives readers a broader view of how MST-related claims compare with overall VA disability claim outcomes.

Claim Type or Review CategoryApproval / Grant RateDenial Rate or Error FindingWhat This Means
MST-related disability claims, 201550%50% deniedIn 2015, VA data showed MST-related claims were granted and denied at roughly equal rates.

Overall VA disability claims, FY202464.6%35.4% deniedThis gives a broad comparison point, although it is not a same-year comparison to the MST claim data above.
VA OIG review of denied MST-related PTSD claims, 2017 review periodN/AEstimated 1,300 of 2,700 denied claims were incorrectly processedThe VA Office of Inspector General found that many denied MST-related PTSD claims may not have been processed according to VA policy.
VA OIG review of denied MST claims, 2025 reportN/A34% of reviewed denied claims had errorsThe OIG found that errors continued even when a second reviewer had agreed with the original denial.
Service-connected MST-related PTSD claims rated 70% or higher, as of April 30, 202167% rated 70% or higherN/AAmong service-connected MST-related PTSD claims, many were rated at a high disability level, showing the serious mental health impact MST can have.

These statistics do not mean every MST claim will be denied. They also do not mean every denial is wrong. But they do show why many survivors feel anxious about the process. Documentation, trauma-informed treatment, and support from an accredited VA claims representative or Veterans Service Organization can be important parts of the process.

What Trauma-Informed Treatment Means for MST Survivors

Trauma-informed care recognizes that many mental health symptoms are connected to what a person has survived. Instead of asking, “What is wrong with you?” trauma-informed care asks, “What happened, how has it affected you, and what helps you feel safe enough to heal?”

For MST survivors, this approach matters. Treatment should not recreate the same powerlessness, pressure, or loss of control that trauma caused.

Trauma-informed treatment may include:

  • Respecting the survivor’s pace
  • Supporting choice and consent
  • Explaining treatment options clearly
  • Helping the person build emotional safety
  • Identifying triggers and trauma responses
  • Reducing shame and self-blame
  • Supporting boundaries
  • Teaching grounding and emotional regulation skills
  • Helping the nervous system learn safety again
  • Addressing PTSD, depression, anxiety, and related symptoms

A trauma-informed approach does not force a survivor to tell every detail before they are ready. Some people begin with symptom relief, sleep support, grounding skills, and emotional stability. Others are ready to process the trauma more directly. Both paths can be valid.

Treatment for Military Sexual Trauma at Montare Behavioral Health

Montare Behavioral Health provides mental health treatment for adults who are struggling with trauma, PTSD, depression, anxiety, and related concerns. For survivors of military sexual trauma, structured mental health care can provide space to step away from survival mode and begin working toward safety, stability, and healing.

Treatment may include individual therapy, group therapy, psychiatric support, trauma-informed clinical care, coping skills, emotional regulation work, and support for co-occurring mental health symptoms. Each treatment plan should be based on the person’s needs, history, symptoms, and goals.

Montare Behavioral Health may support people who are experiencing:

  • PTSD symptoms related to MST
  • Depression or emotional numbness
  • Anxiety, panic, or chronic fear
  • Shame, guilt, or self-blame
  • Sleep disruption or nightmares
  • Difficulty trusting others
  • Relationship struggles
  • Dissociation or feeling disconnected from the body
  • Difficulty functioning at home, work, or school
  • Trauma symptoms that feel hard to manage alone

Healing from MST does not mean pretending it did not happen. It means learning that the trauma does not have to control every part of life.

Rebuilding Safety After Military Sexual Trauma

Safety after MST is not only physical. It is emotional, relational, and internal. A survivor may be away from the person or environment connected to the trauma but still feel unsafe in their body, relationships, or daily life.

Treatment can help survivors rebuild safety through:

  • Grounding techniques
  • Breathwork and calming skills
  • Sleep support
  • Boundary setting
  • Trigger awareness
  • Healthy communication
  • Emotional regulation
  • Self-compassion
  • Shame reduction
  • Reconnection with the body
  • Supportive relationships

These steps may seem small from the outside, but they can be meaningful. Trauma can make a person feel like their body and mind are working against them. Treatment can help them begin to feel more present, more steady, and more in control.

You Do Not Have to Keep Carrying This Alone

Military sexual trauma can make people feel isolated, ashamed, angry, disconnected, or unsafe. But survivors are not alone, and they do not have to prove that their pain is serious enough to deserve help.

You do not need the perfect words. You do not have to share everything at once. You do not have to minimize what happened to make others comfortable. You deserve support that respects your story and your boundaries.

If military sexual trauma has affected your mental health, Montare Behavioral Health can help you explore treatment options for trauma, PTSD, depression, anxiety, and related symptoms. Healing takes time, but support can help you begin to feel safer, more grounded, and more connected again.

Frequently Asked Questions About Military Sexual Trauma

What is military sexual trauma?

Military sexual trauma, or MST, refers to sexual assault or threatening sexual harassment that happens during military service. This can include unwanted sexual contact, sexual coercion, threats, pressure for sexual activity, repeated sexual comments, or any sexual behavior that happens without consent.

Can military sexual trauma affect mental health years later?

Yes. MST can affect a person’s mental health long after the event itself. Some survivors experience PTSD, depression, anxiety, panic attacks, sleep problems, emotional numbness, shame, difficulty trusting others, or trouble feeling safe in relationships. Symptoms may appear right away, or they may become stronger later during stress, major life changes, or other traumatic experiences.

Is MST only experienced by women veterans?

No. MST can affect veterans and service members of any gender. Women veterans are often discussed in relation to MST because they experience high rates of sexual trauma, but men can also be survivors. Male survivors may face added barriers to speaking up because of shame, stigma, fear of judgment, or pressure to appear unaffected.

Do I have to report MST to receive help?

No. A person does not have to have reported military sexual trauma when it happened in order to seek care. Many survivors never reported the event because they felt unsafe, feared retaliation, were not believed, or did not know where to turn. Treatment can still help address the mental health effects of MST.

Can MST lead to PTSD?

Yes. Military sexual trauma can contribute to PTSD, especially when the trauma involved fear, helplessness, betrayal, coercion, or loss of control. PTSD symptoms may include nightmares, flashbacks, intrusive memories, avoidance, emotional distress, irritability, hypervigilance, or feeling constantly on guard.

Can MST cause depression or anxiety?

Yes. MST can be connected to depression, anxiety, panic symptoms, shame, low self-worth, emotional numbness, and relationship struggles. Some survivors feel disconnected from themselves or others. Others may feel like their nervous system is always preparing for danger, even when they are physically safe.

What does trauma-informed treatment mean?

Trauma-informed treatment means care is provided in a way that emphasizes safety, trust, choice, collaboration, and respect. For MST survivors, this is especially important because trauma often involves a loss of control. A trauma-informed approach should not pressure someone to share more than they are ready to discuss.

Will I have to talk about everything that happened?

Not right away. Trauma treatment should move at a pace that feels clinically appropriate and emotionally safe. Some people begin by working on sleep, anxiety, grounding skills, emotional regulation, or daily functioning before discussing the trauma in detail. Survivors should have a voice in their treatment process.

Can I file a VA disability claim for military sexual trauma?

MST itself is not a diagnosis, but a veteran may be eligible for VA disability compensation if MST caused or worsened a physical or mental health condition. This may include PTSD, depression, anxiety, panic disorder, sleep problems, or other trauma-related symptoms. Veterans can contact the VA, a Veterans Service Organization, or an accredited VA claims representative for help with the claims process.

Are MST-related VA disability claims often denied?

MST-related claims have historically had challenges, especially because many survivors did not report the trauma when it happened. VA reporting showed that MST-related claim grant rates improved from 50% in 2015 to 72% in 2021. However, VA Office of Inspector General reviews have also found processing errors in some denied MST-related claims, which is why documentation and qualified claims support can be important.

What kind of evidence can support an MST-related VA claim?

Because MST is often unreported, the VA may consider different types of evidence. This may include medical records, counseling records, statements from people the veteran told, changes in behavior, requests for transfer, work performance changes, or other records showing that something changed after the trauma.

When should someone seek treatment for MST-related symptoms?

Someone should consider seeking treatment if trauma symptoms are affecting sleep, relationships, mood, work, daily functioning, emotional safety, or the ability to feel present in life. A person does not need to wait until symptoms become severe to ask for help. Support can be useful at any stage of healing.
