Gun-related deaths are at a record high, according to a recent report by the Center for Disease Control and Prevention (CDC), rising 35 percent during the first year of the pandemic. Northwestern researcher Linda Teplin, who has been studying the juvenile justice population for more than 25 years, understands youth from low-income neighborhoods are especially vulnerable.

Teplin is the Owen L. Coon Professor of psychiatry and behavioral sciences at Northwestern’s Feinberg School of Medicine and principal investigator of the groundbreaking Northwestern Juvenile Project. Her primary research collaborators include Leah J. Welty and Karen M. Abram of Feinberg.

From the detention centers and jails and back out again in Chicago’s neighborhoods, Teplin’s research team has conducted approximately 18,000 interviews with a cohort of 1,829 formerly incarcerated youth, sampled in the late 90s, to track their mental health and life outcomes.

Study researchers found the likelihood of injury or death by firearm was extremely high for study participants. Graduate student Nanzi Zheng, part of the research team, found that 12 years after the study began, 15% of all study participants had been injured or died from firearm violence; and 16 years later, 23% had been injured or died from firearm violence. Among Black and Hispanic/Latinx males, 27% were injured or died due to firearm violence 16 years after the study began.

The CDC is currently funding several projects aimed at addressing the gun violence epidemic, including a project to distribute free lockboxes, something Teplin has long advocated for.

Teplin’s research underscores the importance of early crime intervention strategies including access to mental health services to circumvent juvenile detention and the downward spiral to poor life outcomes that follows.

On an average day, 37,000 to 38,000 young people reside in juvenile detention. Among poor Black inner-city males, one in four are arrested one or more times before they turn 18, making it an almost normative experience that is too often the start of a dire outcome.

“We think we know a lot about kids in the juvenile justice system,” said Teplin at the annual meeting of the American Association for the 2022 Advancement of Science (AAAS) earlier this year. “But when you look closely at previous studies, the focus is mainly on recidivism. So, we’ve had little information on mental health needs and long-term outcomes.”

The Northwestern Juvenile Project was created to fill the gap in research on the mental health needs and outcomes of youth after they have entered the juvenile justice system.

Teplin organized an AAAS panel event entitled “How Have Studies of Crime Impacted Criminal Justice Policy and Racial Inequality?” during which Teplin discussed how the findings of the Northwestern Juvenile Project have guided the development of new policies.

Among the study’s impacts are new policies to treat youth in the juvenile justice system who have psychiatric disorders. 

“We found that two-thirds of boys and nearly three-quarters of girls had psychiatric disorders when they arrived in detention," Teplin said.

The study data also revealed that among youth with the most serious psychiatric disorders, only one in six received mental health treatment within six months after they left detention.

“This finding has spurred detention centers nationwide to partner with community agencies to make sure these youth are linked up with services when they return home,” Teplin said. 

While substance use disorders were common in the study’s sample, the researchers found that alcohol and marijuana use were the most common drugs used, not hard drugs like heroin or cocaine. 

“In contrast to the ‘War on Drugs’ assumptions and framing, we found that African American males had a far lower rate of substance abuse disorder compared to white males,” Teplin said.

Other key findings with policy implications are the higher rate of detention of youth from lower income neighborhoods, and the participants’ dramatically greater vulnerability and potential for injury and death from firearms violence as they aged.

“We could not have anticipated the high mortality rate of our participants. Remember, our sample was aged 10-18 to start. To date, 13% of our participants have died, nearly half from firearm violence,” Teplin said.

According to Teplin, incarceration should be viewed as the last resort. The study revealed this is not the case for youth in lower income neighborhoods.

“When children from wealthier families get into trouble — say, they sell drugs at school — the school calls the parents, and they avoid the juvenile justice system. When children from poorer families get into trouble, the schools call the police and that child is on a one-way street through the juvenile justice system and beyond,” Teplin said.

In March, Teplin was honored for Distinguished Contributions to Psychology and Law by the American Psychology-Law Society. The award is not given annually but reserved to honor those individuals whose contributions are so unusual as to merit special commendation. Among its previous recipients are Saleem Shah (1986); Supreme Court Justice Harry Blackmun (1990); and Janet Reno (2005).
