Last month, major news outlets reported that a new study had linked concussions to a higher suicide risk among adolescents—but did the media get the story right? In April, headlines such as “Concussions make young people more likely to attempt suicide” (U.S. News and World Report) and “Once-concussed teenagers found to be at higher risk for bullying, suicide” (Education Week) began to appear. Each source referenced a study by Dr. Gabriela Ilie, a post-doctoral fellow at St. Michael’s Hospital in Toronto. Ilie’s study, which was published on April 15 in the science journal Plos One, looked at data from 4,685 surveys administered to adolescents in grades 7 through 12 as part of a 2011 drug use and health survey in Ontario. In the weeks since, however, there has been some criticism, not of the study itself but of the way it was covered by the media. In her April 22 article “The press release that fell and hit its head,” Brenda Goodman, a health writer for the Association of Healthcare Journalists, followed up with Ilie about the study. One of Goodman’s criticisms is that the media coverage—including St. Michael’s own press release—used the word “concussion” to describe the brain injuries that were associated with suicide risk, even though the study itself does not use that word. Instead, the study refers to a narrower band of more traumatic brain injuries, defined as “head injury that resulted in being unconscious for at least 5 minutes or being retained in the hospital for at least one night.” Why is that distinction so important? Goodman points out that more serious brain injuries are likely to be the result of car accidents or assaults; sports-related concussions, while still serious, result in loss of consciousness only about 10 percent of the time. So what did the study actually say about TBI and suicide risk? “When holding constant sex, grade, and complex sample design,” according to Ilie’s findings, “students with TBI had significantly greater odds of reporting elevated psychological distress (AOR = 1.52), attempting suicide (AOR = 3.39), seeking counselling through a crisis help-line (AOR = 2.10), and being prescribed medication for anxiety, depression, or both (AOR = 2.45).” The study goes on to say that students with TBI had higher odds of being bullied or threatened with a weapon at school, compared with students who did not report a TBI. Ilie recommends that physicians screen for potential mental health and behavioral problems in adolescent patients with TBI. This study demonstrated a correlation between some types of TBI and suicide risk in adolescents; it did not, however, show a causal relationship between concussion and suicide. Brenda Goodman and health writers like her remind us that when it comes to psychology news, it’s important to go beyond the headlines and look at the original research.
Over the past two decades, the rate of violent crime in the U.S. and Europe has dropped dramatically. Despite increasingly sensational news stories about crime, we are in fact much less likely to become the victim of a violent crime today than we were in 1990. According to the New York Times, the city of New York had fewer murders last year than in any year since 1963, when reliable record keeping began. In 2013, there were 333 murders in the city, down from 417 in 2012 and a stunning 2,245 in 1991. Chicago, Los Angeles, and Philadelphia also had large declines in violent crime during this period, as did smaller cities across the country. In England, the 2013 murder rate was at a 33-year low, nearly 50% lower than its peak in 1995, according to a recent story in the Guardian. There is no question that the rate of violent crime is significantly lower than it was 20 years ago. Many factors could be contributing to this change, including improvements in law enforcement, reductions in the use of crack cocaine and other drugs, economic changes, and the aging of the population. However, a study by economist Rick Nevin suggests that reductions in the crime rate can be attributed to diminishing levels of lead poisoning from exposure to leaded gasoline and lead paint—and there is a growing body of research that supports his theory. “What makes Nevin’s work persuasive is that he has shown an identical, decades-long association between lead poisoning and crime rates in nine countries,” says the Washington Post’s Shankar Vedantam. In a recent Forbes article, science writer Alex Knapp outlines reasons that Nevin’s theory deserves attention. First, the numbers correlate almost perfectly; when a lag time of 21 years is added (to account for early childhood lead exposure in adult offenders), levels of exposure to lead from gasoline and paint track extremely closely with the U.S. homicide rate (see the graph in Nevin’s 2013 update). Second, the correlation holds true with no exceptions. “Every country studied has shown this same strong correlation between leaded gasoline and violent crime rates,” says Knapp. “Within the United States, you can see the data at the state level. Where lead concentrations declined quickly, crime declined quickly. Where it declined slowly, crime declined slowly. The data even holds true at the neighborhood level—high lead concentrations correlate so well that you can overlay maps of crime rates over maps of lead concentrations and get an almost perfect fit.” Third, the connection between lead poisoning and brain damage is clear. “Not only does lead degrade cognitive abilities and lower intelligence, it also degrades a person’s ability to make decisions by damaging areas of the brain responsible for emotional regulation, impulse control, attention, verbal reasoning, and mental flexibility,” says Knapp. Nevin’s conclusions have been criticized by some, including those who are wary of the implications of linking biology to criminal behavior. In a recent interview with BBC News Magazine, Roger Matthews, a professor of criminology at the University of Kent, said, “The things that push people into crime are very different kinds of phenomena, not in the nature of their brain tissue….There has been a long history of people trying to link biology to crime—that some people have their eyes too close together, or an extra chromosome, or whatever. This stuff gets disproved and disproved. But it keeps popping up.” What do you think about the link between lead levels and crime? Are the correlations strong enough to imply causation? What are the social implications of high lead levels in the blood? PAR wants to hear from you, so leave a comment and join the conversation!
Sometimes, it’s all in the questions you ask. Or the questions y’all ask. Or the ones you guys ask! Those of us in psychology and assessment are very interested in the art of asking the right questions, and a great example from the field of linguistics has been circulating around the Internet in recent months. A dialect survey, based on work by Harvard professor Burt Vaux, has been developed into an interactive quiz by graphic artists at the New York Times, which published it in December 2013. Responses to the quiz generate maps that show the probability that the user hails from a specific region, state, or even city in the U.S. The survey includes questions about the names of specific items (“What do you call a sweetened carbonated beverage?”) as well as pronunciations (“How do you pronounce ‘Aunt’?”). Each answer is association with a region, and there is a “heat map” for each question, as well as a “personal dialog map” for each individual user based on the sum of his or her responses to 25 questions. “The data are fascinating,” says Katherine Wells, in her recent story about Vaux’s work in The Atlantic. “They reveal patterns of migration, unexpected linguistic kinships between regions, and the awesome variety of words we say and how we say them.” An informal poll of users here at PAR headquarters suggests that the quiz can yield some amazingly accurate results—and we come from all over the U.S. Try the quiz yourself and see where it puts you on the map!
