The Impact of Domestic Violence on Children: What Research Shows

The Scope of Children's Exposure to Domestic Violence

Children who live in homes where domestic violence occurs are affected even when they are not the direct targets of abuse. Research from the National Child Traumatic Stress Network estimates that between 10 and 20 percent of children in the United States are exposed to domestic violence in their homes each year.

Exposure does not require witnessing physical violence directly. Children can be affected by overhearing violent arguments, seeing the aftermath of violence (bruises, broken objects, police visits), feeling the tension and fear in the household, being used as pawns or messengers between parents, and witnessing emotional abuse, intimidation, or controlling behavior.

The Child Welfare Information Gateway identifies exposure to domestic violence as a form of child maltreatment in many state laws. Even when a child is not physically harmed, the psychological impact of living in a violent home can be as significant as the impact of direct abuse.

Developmental Impacts by Age

The effects of domestic violence exposure vary by the child's age and developmental stage.

Infants and toddlers (0 to 3 years) may show excessive crying, disrupted sleep patterns, feeding difficulties, and failure to meet developmental milestones. Even very young children who cannot understand what is happening respond to the emotional climate of the household. Elevated stress hormones in the environment can affect brain development during this critical period.

Preschool children (3 to 5 years) may exhibit regressive behaviors such as bedwetting, thumb-sucking, or clinginess. They may develop intense separation anxiety, have frequent nightmares, and show increased aggression in play. Children at this age often believe they are responsible for the violence because they cannot yet understand that adult behavior is not caused by children's actions.

School-age children (6 to 12 years) may have difficulty concentrating in school, show declining academic performance, develop behavioral problems, experience frequent stomachaches and headaches, and struggle with peer relationships. They may feel divided loyalty between parents, experience guilt and shame, and begin to model the aggressive or submissive behaviors they observe at home.

Adolescents (13 to 18 years) may engage in risk-taking behavior including substance use, early sexual activity, and delinquency. They are at increased risk for depression, anxiety, and suicidal ideation. Some teens adopt aggressive behaviors learned from the abusive parent; others develop people-pleasing behaviors learned from the victimized parent. Dating violence is more common among teens who grew up in homes with domestic violence.

Long-Term Psychological Effects

The research on long-term effects is sobering. Children exposed to domestic violence are at significantly elevated risk for developing post-traumatic stress disorder, depression and anxiety disorders, substance use problems in adolescence and adulthood, involvement in violent relationships as adults (either as perpetrators or victims), and difficulties with emotional regulation, trust, and attachment.

The mechanism behind these long-term effects involves the impact of chronic stress on the developing brain. The National Child Traumatic Stress Network explains that repeated exposure to fear-inducing situations activates the child's stress response system at levels and frequencies that exceed what a developing brain can process. Over time, this alters the brain's stress response architecture, making the child more reactive to perceived threats and less capable of emotional regulation.

It is important to note that these outcomes are risk factors, not certainties. Many children who are exposed to domestic violence develop normally, particularly when protective factors are present: a strong relationship with at least one stable, supportive adult; access to mental health services; positive school experiences; and removal from the violent environment.

Why This Matters for DV Education Participants

Understanding the impact on children is a core component of court-ordered domestic violence programs for a specific reason: many participants have not fully considered how their behavior affects their children.

Common rationalizations include "the children were asleep and did not hear anything," "I never hit the kids, so they were not affected," "kids are resilient, they will be fine," and "it is better for children to have two parents, even if the relationship is difficult." Each of these statements contradicts the research evidence.

Children do not need to directly witness violence to be affected by it. They absorb the emotional climate of the home. They respond to a parent's fear, to the tension before incidents, to the quiet aftermath, and to the unpredictability that characterizes violent homes.

For participants who are parents, the impact on children can be a powerful motivator for change. Understanding that your behavior is measurably affecting your child's brain development, emotional health, and future relationships provides a concrete reason to engage fully with the skills taught in your court-ordered program.

Resources for Families

If children in your family have been exposed to domestic violence, professional support is available and recommended.

The National Child Traumatic Stress Network (nctsn.org) provides resources for families and referrals to trauma-informed therapists who specialize in working with children affected by domestic violence.

The National Domestic Violence Hotline (1-800-799-7233) provides safety planning and referrals for families currently experiencing domestic violence.

Trauma-focused cognitive behavioral therapy (TF-CBT) is an evidence-based treatment specifically designed for children who have experienced trauma, including domestic violence exposure. It is available through many community mental health centers.

School counselors can be a first point of contact for identifying and supporting children who are struggling. If your child is showing signs of behavioral or emotional difficulties, contacting their school counselor can connect you with appropriate resources.
