Study Reveals Risk Factors That Lead To PTSD

PHILADELPHIA (CBS) - Post Traumatic Stress Disorder, or PTSD, is a major complication for soldiers fighting wars.  There are obvious reasons for this.  Stress, the concern over life and death and a fear of the unknown often contribute.

But, when soldiers witness death and destruction directly, they can have long term effects. But what soldiers are at greater risk to develop PTSD?  Are there certain characteristics?  Are there certain ways to find out?

According to a new study in the Archives of General Psychology, military service members who screen positive for PTSD before they were deployed were five times more likely to develop the condition. There were other risk factors. Those who took psychiatric drugs before deployment were 2 1/2 times more likely.  Experts say early intervention is necessary for people at risk.
