Stress of Rejection in School Kids can be Reduced by Good Friendships

A new study says that friendships can serve as a buffer against the negative effects of classmates' rejection that can cause stress in school children.

Cortisol, a human stress hormone, mobilizes energy and helps us respond to potential threat when we're under stress.

Increased levels of cortisol are adaptive-they help us adapt how we function to changing circumstances and cope with stressors when they occur-but chronically high levels can have negative effects on how we function, especially on our immune system.

The new study looked at almost 100 fourth graders-an age that's been understudied in this regard-to determine whether victimization and exclusion by peers were related to increases in cortisol, and whether friendships moderated this association.

The researchers at Radboud University Nijmegen, Netherlands, found that children who were excluded by their classmates had elevated levels of cortisol at school.

And they had a smaller decline in cortisol over the course of the day.

Both of these findings may indicate that exclusion is stressful.

This was even more pronounced for excluded kids who had few friends or had friendships that were characterized as low in quality.

Victimization by classmates wasn't associated with increased cortisol levels, suggesting that victimization is not as stressful as exclusion.

"Together, the results demonstrate that although friends cannot completely eliminate the stress of exclusion at school, they do reduce it," according to Marianne Riksen-Walraven, professor of developmental psychology at Radboud University Nijmegen.

"And the number and quality of children's friendships can serve as a buffer against being rejected," he added.

The study appeared in the journal Child Development.
