RICHMOND, Va. (AP) — A study says that about 15 percent of Virginia Tech students reported experiencing high levels of post-traumatic stress symptoms several months after the 2007 shooting rampage that left 33 people dead.

The study was published last month in the journal Psychological Trauma: Theory, Research, Practice and Policy.

It measured trauma-related stress and possible post-traumatic stress after the deadliest mass shooting by a single gunman in modern U.S. history.

The survey of more than 4,600 students in summer and fall 2007 said that 23 percent of women and about 10 percent of men reported high post-traumatic stress symptoms.

Nearly 65 percent of students reported being unable to confirm their friends' safety after shootings, and 9 percent reported having a close friend killed.
