She said that psychological therapy is urgently needed, since survivors are still gripped in horror, and by a sense of insecurity and solitude.
"They re-experienced the horrible scenes again and again in everyday nightmares or insomnia. The trauma may remain for two to 10 years," she said.
Zhang Kan, director of the Psychological Research Institute of the Chinese Academy of Social Sciences said that millions of quake victims, witnesses, rescuers and even reporters on the earthquake may suffer psychological trauma, and need counseling.
"Some people may not handle the helpless emotion, and suffer long-time panic, the feeling of setback and emotional dysphoria. Such patients may turn to liquor, cigarettes and drugs for comfort. Some may contemplate suicide or other extreme behavior," said Zhang.
Thousands of volunteers from around the country have registered through local psychological service stations to go to the rescue front line. However, there is still a heavy shortage of professional psychologists, since the therapy is in an initial developing stage even in China's major cities.
