There are pros and cons to the support that victimized teenagers get from their friends. Depending on the type of aggression they are exposed to, such support may reduce youth's risk for depressive symptoms. On the other hand, it may make some young people follow the delinquent example of their friends, says a team of researchers from the University of Kansas in the US, led by John Cooley. Their findings are published in Springer's Journal of Psychopathology and Behavioral Assessment.
