Increased attention to sad faces predicts depression risk in teenagers

Teenagers who tend to pay more attention to sad faces are more likely to develop depression, but specifically within the context of stress, according to new research from Binghamton University, State University of New York.

Researchers at Binghamton University, led by graduate student Cope Feurer and Professor of Psychology Brandon Gibb, aimed to examine whether attentional biases to emotional stimuli, assessed via eye tracking, serve as a marker of risk for depression for teenagers.

"Although previous studies from the lab have examined who is most likely to show biased attention to sad faces and whether attention to sad faces is associated with risk for depression, the current study is the first to look at whether these attention biases impact how teenagers respond to stress, both in the lab and in the real world," said Feurer.

Biased attention to sad faces is associated with depression in adults and is hypothesized to increase depression risk specifically in the presence, but not absence, of stress by modulating stress reactivity. However, few studies have tested this hypothesis, and no studies have examined the relation between attentional biases and stress reactivity during adolescence, despite evidence that this developmental window is marked by significant increases in stress and depression risk.

Seeking to address these limitations, the new study examined the impact of adolescents' sustained attention to facial displays of emotion on individual differences in both mood reactivity to real-world stress and physiological reactivity to a laboratory-based stressor. Consistent with vulnerability-stress models of attention, greater sustained attention to sad faces was associated with greater depressive reactions to real-world stress.

"If a teenager has a tendency to pay more attention to negative stimuli, then when they experience something stressful they are likely to have a less adaptive response to this stress and show greater increases in depressive symptoms," said Feurer. "For example, if two teenagers both have a fight with a friend and one teenager spends more time paying attention to negative stimuli (i.e., sad faces) than the other, then that teenager may show greater increases in depressive symptoms in response to the stressor, potentially because they are paying more attention to the stressor and how the stressor makes them feel."

The researchers believe that the biological mechanism behind this finding lies in the brain's ability to control emotional reactivity.

"Basically, if the brain has difficulty controlling how strongly a teenager responds to emotions, this makes it harder for them to look away from negative stimuli and their attention gets 'stuck,'" said Feurer. "So, when teenagers who tend to pay more attention to sad faces experience stress, they may respond more strongly to this stress, as they have difficulty disengaging their attention from negative emotions, leaving these teens at increased risk for depression."

"This is also why we believe that findings were stronger for older than younger adolescents. Specifically, the brain becomes more effective at controlling emotional reactivity as teens get older, so it may be that being able to look away from negative stimuli doesn't protect against the impact of stress until later adolescence."

There is increasing research showing that the way teenagers pay attention to emotional information can be modified through intervention, and that changing attention biases can reduce risk for depression. The current study highlights attention toward sad faces as a potential target for intervention, particularly among older teenagers, said Feurer.

The researchers recently submitted a grant that would let them look at how these attention biases change across childhood and adolescence.

"This will help us better understand how this risk factor develops and how it increases risk for depression in youth," said Gibb. "Hopefully, this will help us to develop interventions to identify risk for these types of biases so that they can be mitigated before they lead to depression."

Depression is on the rise in the US, especially among young teens

Depression is on the rise in the United States. From 2005 to 2015, depression rose significantly among Americans age 12 and older with the most rapid increases seen in young people. This is the first study to identify trends in depression by gender, income, and education over the past decade.

This is the first study to identify trends in depression by gender, income, and education over the past decade.

"Depression appears to be increasing among Americans overall, and especially among youth," said Renee Goodwin, PhD, of the Department of Epidemiology, Mailman School of Public Health, who led the research. "Because depression impacts a significant percentage of the U.S. population and has serious individual and societal consequences, it is important to understand whether and how the prevalence of depression has changed over time so that trends can inform public health and outreach efforts."

The results show that depression increased significantly among persons in the U.S. from 2005 to 2015, from 6.6 percent to 7.3 percent. Notably, the rise was most rapid among those ages 12 to 17, increasing from 8.7 percent in 2005 to 12.7 percent in 2015.

Data were drawn from 607,520 respondents to the National Survey on Drug Use and Health, an annual U.S. study of persons ages 12 and over. The researchers examined the prevalence of past-year depression annually among respondents based on DSM-IV criteria.

The increase in rates of depression was most rapid among the youngest and oldest age groups, whites, the lowest income and highest income groups, and those with the highest education levels. These results are in line with recent findings on increases in drug use, deaths due to drug overdose, and suicide.

"Depression is most common among those with least access to any health care, including mental health professionals. This includes young people and those with lower levels of income and education," noted Goodwin. "Despite this trend, recent data suggest that treatment for depression has not increased, and a growing number of Americans, especially socioeconomically vulnerable individuals and young persons, are suffering from untreated depression. Depression that goes untreated is the strongest risk factor for suicide behavior and recent studies show that suicide attempts have increased in recent years, especialy among young women."

Depression frequently remains undiagnosed, yet it is among the most treatable mental disorders, noted the researchers. "Identifying subgroups that are experiencing significant increases in depression can help guide the allocation of resources toward avoiding or reducing the individual and societal costs associated with depression," said Goodwin.
