Half of U.S. high schoolers say they have bullied or teased someone at least once in the past year, and nearly half say they have been bullied in that time, one of the largest studies ever on bullying finds.

The study surveyed 43,321 teens ages 15 to 18, from 78 public and 22 private schools. It finds 50% said they had "bullied, teased or taunted someone at least once," and 47% had been "bullied, teased or taunted in a way that seriously upset me at least once."

The survey findings are from the Ethics of American Youth Survey by the Josephson Institute of Ethics, a non-profit based in Los Angeles that has surveyed teens on conduct and behavior every two years since 1992. This is the first time it has reported on bullying.

It also found that in the past 12 months:
•52% of students have hit someone in anger.
•28% (37% of boys, 19% of girls) say it's OK to hit or threaten a person who angers them.
