What gun violence does to our mental health


Community members gather at the Uvalde County Fairplex to pray for those affected by the massacre at Robb Elementary School in Uvalde, Texas on Wednesday, May 25, 2022.

Heather Martin was a senior at Columbine High School in Colorado in 1999 when two gunmen, also teenagers, killed 13 people and wounded 21 more before taking their own lives. She ended up barricaded in a room for three hours. And although she wasn’t physically injured, she witnessed the aftermath of the shooting, which she described as “horrifying.”


Despite having survived such a traumatic event, she did not consider how deeply her mental health might have been affected. “I minimized my own experience and always thought, ‘Someone has it worse. I should just be fine or be better,’” she said.


But she wasn’t fine. Martin had recurring nightmares for years and eventually dropped out of college after developing an eating disorder and taking recreational drugs.


It wasn’t until the 10th anniversary of the shooting that she finally found the support she needed and reconnected with some of her classmates “who got it, who were also struggling, who didn’t judge me,” she said.


Mass shootings have become more common during the pandemic, and so, too, have other types of gun violence. So far this year, there have been more than 200 mass shootings in the United States, including the one that caused the deaths of 19 children and two teachers in Uvalde, Texas, last Tuesday. But beyond the statistics is a number that is harder to quantify: the large swath of people grappling with the psychological effects that stem from the violence.


The mental health toll doesn’t just affect those closest to gun violence. It also ripples through a community and the nation, said Erika Felix, an associate professor of clinical psychology at the University of California, Santa Barbara, who has studied survivors of shootings.


“It’s felt everywhere,” she said. “We really have to look at this as a public mental health crisis.”


For survivors, victims’ families and those who live near the location of a shooting, the psychological effects can be intense and prolonged. They may include post-traumatic stress disorder, substance abuse, self-harm and major depressive disorders.


Could have happened to any of us


In a 2018 survey conducted by the Harris Poll for the American Psychological Association, 75% of people ages 15-21 said mass shootings were significant sources of stress for them. Most people ages 22-72 said the same.


The fact that the shooting in Uvalde could have happened to any of us “is deeply unsettling,” said Dr. Sara Johnson, a professor of pediatrics at Johns Hopkins University School of Medicine who has studied how chronic stress affects child development and behavior.


Some people may develop a sense that the world is not a safe place, that others cannot be trusted “or that they are powerless to change the circumstances in which they’re living,” Johnson said. “These kinds of mass shootings really tear at the fabric of society.”


But despite the potential for far-reaching psychological effects, there is limited data on what firearm injury does to our collective mental health.


PTSD symptoms can be similar in adults and children, said Nicole Nugent, an associate professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University and an expert in PTSD identification and treatment.


Those with PTSD often have trouble sleeping and may become emotionally numb, continuously on edge or easily startled, she said. The world will often feel unsafe to them, and upsetting memories may intrude on their daily thoughts. Some people may try to avoid things that remind them of their trauma. Teens and adults might turn to substance abuse.


Younger children may experience stomachaches or headaches, as well as lower-grade anxiety that causes them to misbehave or have trouble concentrating. They may also engage in “traumatic play,” acting out the trauma they experienced, Nugent said. If the behavior persists, she said, “then we start to worry that it could be signaling something significant like PTSD.”


Proximity to violence


Much like those who experience gun violence, those who live near it may also suffer.


Dr. Aditi Vasan, a general pediatrician at Children’s Hospital of Philadelphia, decided to investigate how children in her community were psychologically affected by nearby shootings after speaking with patients who had anxiety, depression or difficulty sleeping.


“When I asked them when these symptoms started, they told me it was after a classmate or a friend or a neighbor was shot,” she said.


The resulting study, published in JAMA Pediatrics in 2021, examined emergency department admissions between 2014 and 2018 and found that children and teenagers in west and southwest Philadelphia who lived within about four to six blocks of where a shooting had occurred were more likely than other children to use an emergency room for mental health reasons during the two months after the shooting. The odds rose among children who were exposed to multiple shootings and among those who lived closest to a shooting’s location, within two or three blocks. Their symptoms included anxiety, panic attacks, suicidal ideation and self-harm behavior, Vasan said.


Addressing the psychological effects of gun violence


For younger children affected by violence, Nugent recommended keeping as much structure in place as possible, such as regular bedtimes and mealtimes.


“They are looking to us for those subtle signals that things are OK and things are safe,” she said.


Shortly after the shooting in a movie theater in Aurora, Colorado, in 2012, Martin and one of her high school friends co-founded the Rebels Project, a nonprofit, nonpartisan peer support group for those directly affected by mass violence. With about 1,700 members, it is one of the largest organizations of its kind, she said.


People will “push down their trauma and their experiences, and it can lead to some really dangerous places,” said Martin, now 41 and a high school English teacher in Aurora. “It’s really about acknowledging that you are impacted.”
