The Violence That Happens Behind Closed Doors
One in three women worldwide will experience physical or sexual violence from an intimate partner during her lifetime. That's not a typo. One in three.
This statistic, from the World Health Organization, represents hundreds of millions of people—daughters, mothers, sisters, friends, colleagues. And while the numbers are staggering, they likely undercount the true scope of the problem. Violence between intimate partners is notoriously underreported, shrouded in shame, fear, and the complicated emotions that come with loving someone who hurts you.
Intimate partner violence, often abbreviated as IPV, refers to harm inflicted by a current or former spouse, boyfriend, girlfriend, or romantic partner. It encompasses far more than physical assault. The World Health Organization defines it as "any behavior within an intimate relationship that causes physical, psychological or sexual harm to those in the relationship, including acts of physical aggression, sexual coercion, psychological abuse and controlling behaviors."
That last category—controlling behaviors—is crucial to understanding how this violence actually works.
Two Very Different Kinds of Violence
Here's something researchers discovered that changed how we understand domestic violence: not all intimate partner violence is the same. In fact, there are fundamentally different types that arise from different dynamics and require different responses.
The most dangerous form is called intimate terrorism, or coercive controlling violence. In these relationships, one partner—typically a man—systematically dominates and controls the other through a combination of threats, intimidation, isolation, and violence. The physical abuse, when it occurs, is severe. But the core of intimate terrorism is psychological: controlling what the victim wears, who they see, where they go, how they spend money, and how they think about themselves.
Research from 2001 found that 97 percent of intimate terrorism perpetrators were men. This is the form of domestic violence most likely to require emergency medical care and women's shelters. It's the kind that tends to escalate over time, becoming more severe and more dangerous.
Then there's situational couple violence, which looks completely different. This is what happens when an argument between partners escalates until one or both people lash out physically—pushing, slapping, throwing things. It's not about systematic control. It's about conflict that gets out of hand.
Situational couple violence is actually the most common form of intimate partner violence, particularly among younger couples. And here's something that surprises many people: men and women commit it at roughly equal rates. One study of college students found women perpetrated about 44 percent of situational couple violence and men about 56 percent.
This doesn't mean the consequences are equal. Men generally cause more serious injuries when they become violent, simply because they're typically larger and stronger. But the dynamic itself—conflict escalating into aggression—occurs across genders.
Why the Distinction Matters
Understanding the difference between these types of violence matters enormously for intervention. Couples counseling might help partners who occasionally lose their tempers during arguments learn better conflict resolution skills. But couples counseling is actively dangerous for victims of intimate terrorism—it can give the abuser more tools for manipulation and put the victim at greater risk.
There's also a third category worth understanding: violent resistance. This is when victims of intimate terrorism fight back against their abusers. Within relationships characterized by intimate terrorism and violent resistance, 96 percent of those who resist violently are women defending themselves against male abusers.
Sometimes this resistance is instinctive, a reaction to an attack. Sometimes it's a defensive mechanism that develops after prolonged abuse. And sometimes—tragically—it becomes fatal when the victim feels that killing their abuser is the only way to escape.
The Cascade of Consequences
The injuries most often seen in IPV victims tell their own grim story: bruises, cuts, and broken bones, frequently concentrated on the head, neck, and face. Strangulation injuries are particularly ominous—they're one of the strongest predictors that future violence will be severe or deadly. Concussions and traumatic brain injuries are common, sometimes occurring repeatedly over years of abuse.
But the physical wounds are only part of the damage.
Victims of intimate partner violence are significantly more likely to experience depression, anxiety, and post-traumatic stress disorder—that deep psychological wound that makes a person relive trauma over and over, hypervigilant to any reminder of what happened to them. Nearly half of women reporting serious domestic violence meet the criteria for major depression. About a quarter suffer from PTSD. Almost a third experience severe anxiety.
Many turn to substances to cope. Tobacco use rises among IPV victims. So does alcohol and drug abuse. These aren't character failures—they're attempts to numb unbearable pain.
Women who experience intimate partner violence face higher rates of unintended pregnancies and sexually transmitted infections, including HIV. This happens because of forced sex and something researchers call reproductive coercion: a partner removing a condom without consent, or blocking access to birth control.
And the damage ripples outward through generations. Children who witness intimate partner violence—who grow up in homes where one parent terrorizes the other—are more likely to become victims of IPV themselves as adults. Or perpetrators.
Violence teaches violence.
Who's at Risk?
Research has identified patterns that help predict who is more likely to experience or perpetrate intimate partner violence. These aren't judgments—they're risk factors that help target prevention efforts.
Women who had children by age 21 were twice as likely to become victims of intimate partner violence compared to women who weren't mothers at that age. Young parenthood often brings financial stress, social isolation, and relationship strain—all factors that can create conditions where violence flourishes.
Men who became fathers by 21 were more than three times as likely to become abusers compared to men who weren't fathers at that age. The stresses of early parenthood seem to interact with other risk factors to increase the likelihood of violence.
Income matters too. The lower a household's income, the higher the reported rates of intimate partner violence. Poverty creates stress, limits options, and can trap victims in dangerous situations. It's also bidirectional: intimate partner violence impairs victims' ability to find and keep employment, which deepens poverty, which makes escape even harder.
Substance abuse plays a significant role. More than two-thirds of men who commit or attempt to kill their partners were using alcohol, drugs, or both during the incident. Less than one-fourth of victims had used substances. This isn't about excusing violence—people are responsible for their actions regardless of intoxication—but it does highlight how substances can lower inhibitions and amplify aggression.
The Psychology of Violence
Researchers have developed a framework called the I-cubed Theory—written as I³—to explain how intimate partner violence happens. It describes three processes that interact to determine whether a conflict will escalate into violence: instigation, impellance, and inhibition.
Instigation is the spark. Something happens that creates conflict: one partner discovers the other has been unfaithful, or feels rejected, or perceives some other threat. This triggering event sets the stage.
Impelling factors are characteristics that make violence more likely once the spark exists. Poor communication skills mean the conflict can't be resolved through discussion. Alcohol or drug use lowers inhibitions. A history of abuse—either experiencing or witnessing it—normalizes violence as a response. Impulsiveness and weak self-control make it hard to step back from escalating anger.
Inhibiting factors are the brakes. Empathy—the ability to understand how your actions affect another person—reduces violence. So does economic prosperity, which reduces stress and provides alternatives. Strong self-control helps people pause before acting on aggressive impulses. Clear consequences for violence—whether legal, social, or relational—give people reasons to hold back.
When instigation is weak, impelling factors are minimal, and inhibiting factors are strong, intimate partner violence is unlikely. When instigation is strong, impelling factors are numerous, and inhibiting factors are absent, violence becomes probable.
This framework applies across all relationship types: heterosexual and same-sex, male-on-female and female-on-male. The specific risk factors may differ, but the underlying dynamic of instigation, impellance, and inhibition remains consistent.
The Role of Beliefs
What people believe about relationships and gender shapes how they respond to intimate partner violence—and how likely they are to perpetrate or excuse it.
Research based on Ambivalent Sexism Theory found that people who hold sexist attitudes are more accepting of myths that justify intimate partner violence. If you believe women are naturally subordinate to men, or that women provoke violence through their behavior, you're more likely to blame victims for their abuse.
Two specific beliefs proved especially predictive: hostility toward women and benevolence toward men. Both contribute to legitimizing partner violence and undervaluing its seriousness.
Romantic myths also play a role. Researchers found that beliefs in the transformative power of love—that love can overcome any obstacle, that true love requires suffering, that jealousy proves devotion—correlate with greater tolerance for controlling behavior in relationships.
Young people aged 18 to 30 who strongly believed in these romantic myths were more likely to engage in "cyber-control" of their partners: monitoring their social media, demanding passwords, restricting who they could communicate with online. Adults who held these beliefs showed higher rates of justifying intimate partner violence.
The cultural stories we tell about love have consequences.
Screening for Danger
Because intimate partner violence is so common and so damaging, the United States Preventive Services Task Force recommends that healthcare providers screen all women of reproductive age for IPV and provide resources to those who screen positive.
Several screening tools have been developed and tested. One of the most widely used is called HITS, an acronym for Hurt, Insult, Threaten, and Scream. It asks four questions, each rated on a scale from one (never) to five (frequently). How often does your partner physically hurt you? Insult you? Threaten you with harm? Scream or curse at you? Higher scores indicate higher likelihood of abuse.
Another tool is the Danger Assessment, which evaluates risk of severe injury or death. It asks five questions: Has the abuse become more frequent in the past year? Has your partner used weapons? Do you believe your partner is capable of killing you? Has your partner choked you? Is your partner violently and constantly jealous? Answering yes to two or more of these questions suggests high risk of severe injury or death.
That question about choking deserves special attention. Strangulation is one of the most dangerous forms of intimate partner violence. It can cause death in minutes, often leaves no visible marks, and is strongly predictive of future lethal violence. When someone puts their hands around their partner's throat, they're communicating something: I could kill you.
The Batterer's Profile
Researchers who study intimate terrorists—the most dangerous category of abusers—have identified two main subtypes.
The first is the "generally-violent-antisocial" type. These individuals have psychopathic tendencies and are violent across many contexts, not just with intimate partners. They may have criminal histories, show little empathy for anyone, and use violence instrumentally to get what they want.
The second is the "dysphoric-borderline" type. These individuals are emotionally dependent on their relationships to an unhealthy degree. They may oscillate between idealization and devaluation of their partners, experience intense fear of abandonment, and use violence as a desperate attempt to prevent their partner from leaving.
Both types share something important: they're more likely than other violent people to have witnessed abuse as children. The pattern of violence was modeled for them early. They learned that intimate relationships involve domination and fear.
This doesn't excuse their behavior. Millions of people witness domestic violence as children and never become abusers. But it does suggest that breaking the cycle of violence requires intervention across generations.
Beyond the Statistics
Numbers can obscure as much as they reveal. Behind every statistic about intimate partner violence is a human being navigating impossible choices.
Why doesn't she just leave? It's the question everyone asks, and it misses everything important. Leaving is the most dangerous time. Abusers often escalate to lethal violence when they feel they're losing control. Victims may have no money, no job, no place to go. They may have children they can't support alone. They may still love their abuser, or remember the person their abuser used to be, or believe the promises that things will change.
The average victim attempts to leave seven times before leaving permanently. Each attempt teaches them something about the obstacles they face and the resources they need.
Understanding intimate partner violence means understanding that the violence is only part of the story. The isolation is part of it too—how abusers cut victims off from friends and family until they have no support system left. The economic control is part of it—how abusers ensure victims have no money of their own. The psychological manipulation is part of it—how abusers convince victims that the abuse is their own fault, that no one else would want them, that they deserve what's happening to them.
This is why simply asking "are you being abused?" isn't always enough. Victims may not identify their experience as abuse. They may be too afraid to admit it. They may believe—correctly—that disclosure will put them in greater danger.
The work of ending intimate partner violence is slow and complicated. It requires changing laws, changing institutions, changing cultural narratives about relationships and gender, and changing individual beliefs held by millions of people. It requires providing victims with real options: safe housing, economic independence, legal protection, psychological support.
One in three women. That's the number we started with. It's also the number we end with, because until it changes, there's work to be done.
