A government-funded analysis finds that comparatively little is known about how to effectively treat child victims of traumatic events, even though such occurrences are common.
A report sponsored by the federal Agency for Healthcare Research and Quality finds that school-based counseling treatments showed the most promise in helping young survivors and witnesses heal.
But there's no hard proof that anxiety drugs or other medication work and far more research is needed to provide solid answers.
According to the report, about two-thirds of U.S. children and teens younger than 18 will experience at least one traumatic event, including shootings and other violence, car crashes and weather disasters.
Most will not suffer any long-term psychological problems, but about 13 percent will develop symptoms of post-traumatic stress.
The report's concludes that no one knows which treatments are best, or if some work better in certain situations.
