- Summary:
- A new study found that children who are very distressed when their parents fight have higher levels of the stress hormone cortisol. Distress, hostility, and level of involvement parental arguments were measured in 208 six-year olds. Cortisol levels were measured by taking saliva samples before and after simulated telephone arguments between their parents. Children who were very distressed and very involved in response to parental fighting had especially high cortisol levels.

Children who become very upset when their parents fight are more likely to develop psychological problems. But little is known about what happens beyond these behavioral reactions in terms of children's biological responses. A new study has found that children who are very distressed when their parents fight also have higher levels of cortisol, a stress hormone.
The study is by researchers at the University of Rochester, the University of Minnesota, and the University of Notre Dame.
The researchers studied 208 primarily White 6-year-olds and their mothers to determine whether children who showed specific behavior patterns of reacting to conflict also had changes in cortisol levels during simulated telephone arguments between their parents. They measured children's distress, hostility, and level of involvement in the arguments, and received reports from the mothers about how their children responded when parents fought at home. Cortisol levels were measured by taking saliva samples before and after the conflicts in the lab.
Children who were very distressed by the conflicts in the lab had higher levels of cortisol in response to their parents fighting. Children's levels of hostility and their involvement during the arguments weren't always related to their levels of cortisol, the study found. But children who were very distressed and very involved in response to parental fighting had especially high levels of cortisol.
"Our results indicate that children who are distressed by conflict between their parents show greater biological sensitivity to conflict in the form of higher levels of the stress hormone, cortisol," according to Patrick T. Davies, professor of psychology at the University of Rochester, who led the study. "Because higher levels of cortisol have been linked to a wide range of mental and physical health difficulties, high levels of cortisol may help explain why children who experience high levels of distress when their parents argue are more likely to experience later health problems."
The study has implications for policy and practice: The common practice of judging how well intervention programs are doing based solely on improvements in how children function psychologically may need to be changed to include physiological measures like cortisol levels, the authors suggest.
The study was funded in part by the National Institute of Mental Health.
