Psychological problems like post traumatic stress disorder are relatively common after an individual experiences a traumatic event like a natural or manmade disaster. However, some people are more resilient than others. A group of psychologists recently identified some of the factors that make a person more susceptible to long-term effects of trauma.

Reporting in the journal Psychological Science in the Public Interest, George Bonanno, Chris R. Brewin, Krzysztof Kaniasty, and Annette M. La Greca said that age and socioeconomic status play large roles in determining whether or not someone is likely to develop post traumatic stress disorder.

After reviewing the results of previous clinical trials, the researchers found that roughly 30 percent of individuals who experience trauma develop long-term psychological problems. Younger adults are at the greatest risk of complications, while individuals of lower socioeconomic status are also more susceptible.

The researchers said that psychological intervention may benefit individuals who have experienced trauma. When these people receive therapy before symptoms of complications begin to emerge, they have a better chance of avoiding conditions like post traumatic stress disorder.
