Support for survivors of domestic violence is important, but to end domestic violence once and for all, society needs to understand the people who perpetrate it and how to successfully intervene.
Domestic violence is very common in the United States. Nearly half of women and men in the U.S. experience sexual or physical violence, stalking or psychological harm or coercion in a romantic relationship during their lifetime.
Domestic violence is also experienced unevenly across the U.S population. Young people are most vulnerable, with nearly three-fourths of female victims reporting that their first experience of domestic violence occurred before age 25. People of color and LGBTQ+people also experience considerably higher rates of domestic violence than the national average. And despite similar rates of domestic violence across men and women, women report more severe effects on their lives, including higher rates of injury and need for medical care, needing help from law enforcement and post-traumatic stress disorder symptoms.
I am a social worker who has spent the past 10 years studying how men come to use violence against their intimate partners, since the effects of their violence is often the most severe. My research has found that consistent supportive relationships with attentive adults in childhood and adulthood, along with stress management that takes trauma into account, are two promising approaches to prevent domestic violence.
The roots of domestic violence
Understanding how someone comes to perpetrate violence is necessary to stop violence from happening in the first place.
Certain childhood experiences can put people at risk of committing domestic violence in the future. Researchers have found that child abuse, neglect and a negative parent-child relationship are significant risk factors that may lead someone to later perpetrate domestic violence.
Experiencing trauma in early childhood can alter the brain, how the body responds to stress and whether someone sees the world as a threatening, harmful and untrustworthy place. For example, research has shown that people who have been exposed to trauma have increased activity in the amygdala of the brain, resulting in heightened fear and arousal that can lead to aggressive responses in the face of conflict and stress. Trauma exposure is also linked to a decrease in activity in the prefrontal cortex – that’s the part of the brain responsible for impulse control, concentration and emotional reasoning. These are essential qualities to navigate interpersonal relationships.
Toxic stress – excessive or prolonged activation of the body’s stress response – happens when someone encounters constant threats to their physical or mental safety during sensitive developmental periods. Compared to their peers, youth facing disproportionate levels of hardship and threats of poverty, racism and other structural inequities are at greater risk for toxic stress. These bodily changes can set kids up for PTSD, depression, and alcohol or drug abuse later in life, which are some of the most common risk factors of perpetrating domestic violence. One study found that nearly one-third of men in a domestic violence intervention program reported clinical levels of PTSD.
