Study links adolescent bullies to criminal behavior later

"Adults who say they bullied others when they were adolescents may have a higher likelihood of engaging in criminal behavior later in life, according to new research from UT Dallas.

"The study, which appeared in the Journal of Youth and Adolescence, examined data gathered on a group of more than 400 men over the course of several decades. 

"This is the largest long-term study of bullying behavior," said Dr. Nadine Connell, assistant professor of criminology and co-author of the paper. "This is important because it helps us gauge whether bullying is a risk factor for determining continued adverse behavior well into late-middle adulthood."
