Intervention helps decrease 'mean girl' behaviors, researchers find

Relational aggression, or 'mean girl' bullying, is a popular subject in news and entertainment media. This nonphysical form of aggression generally used among adolescent girls includes gossiping, rumor spreading, exclusion and rejection. As media coverage has illustrated, relational aggression can lead to tragic and sometimes fatal outcomes. Researchers have now developed and tested an intervention that effectively decreases relational aggression among teen girls.
