Research: Depressed adolescents at risk for developing anxiety

The study found that among youth who have symptoms of depression, the risk is most severe for those who have one or more of three risk factors, said SMU psychologist Chrystyna Kouros, who led the study.

Specifically, those who are most vulnerable are those who have a pessimistic outlook toward events and circumstances in their lives; those who have mothers with a history of an anxiety disorder; or those who report that the quality of their family relationships is poor, Kouros said.

A depressed adolescent with any one of those circumstances is more at risk for developing anxiety, the researchers found. The findings suggest that mental health professionals could target adolescents with those risk factors. Early intervention might prevent anxiety from developing, Kouros said.

“Depression or anxiety can be debilitating in itself,” said Kouros, an assistant professor of psychology in SMU’s Dedman College of Humanities and Sciences. “Combined, however, they are an even bigger threat to a child’s well-being. That’s particularly the case during adolescence, when pre-teens and teens are concerned about fitting in with their peers. Anxiety can manifest as social phobia, in which kids are afraid to interact with friends and teachers, or in school refusal, in which children try to avoid going to school.”

The findings are reported in Development and Psychopathology. The study, “Dynamic temporal relations between anxious and depressive symptoms across adolescence,” appears on the journal’s web site.

Kouros co-authored the research with psychiatrist Susanna Quasem and psychologist Judy Garber, both of Vanderbilt University. Data for the study were collected by Garber, a Vanderbilt professor of psychology and human development.

The finding was based on data from 240 children from metropolitan public schools and their mothers, all of whom were assessed annually for six years. The children were followed during the important developmental period from sixth grade through 12th grade. The study was evenly divided between boys and girls.

Consistent with previous research, the authors found also that “symptoms of anxiety were a robust predictor of subsequent elevations in depressive symptoms over time in adolescents.” That link has been known for some time, Kouros said, and the current study confirmed it.

Less well understood by researchers, however, has been the link between depressive symptoms developing further into elevated anxiety, she said.

“The current study showed that depressive symptoms were followed by elevations in anxious symptoms for a subset of youth who had mothers with a history of anxiety, reported low family relationship quality, or had a more negative attributional style,” the authors reported.
