RESUMO
SCI-E and SSCI covered papers on psychiatry published from 2002 to 2011 by authors of China, USA and Japan were analyzed using bibliometrics and the number, relative impact power and international cooperation of these papers were compared among the 3 countries, which showed that both the number and impact power of SCI-E and SSCI covered papers on psychiatry published by authors of China increased, the number of papers published by authors of China was catching up with that published by authors of Japan, and the impact power of papers published by authors of China was higher than that published by authors of Japan.However, they were significantly lower than those published by authors of USA.It is quite important to publish papers in journals with a high academic level and to strengthen international cooperation for increasing the domestic scientific research level in psychiatry.
