International publication trends in the traumatic stress literature.

This analysis looked at international publication trends in the field of trauma by examining first author affiliations of over 13,000 trauma publications from 1987 to 2001. Searches were conducted using the Published International Literature on Traumatic Stress (PILOTS) database to determine frequency of international contributions. A similar search of the Journal of Traumatic Stress (JTS) was also conducted. Although the majority of trauma research comes from investigators in North America, examining publication trends over time revealed that trauma research is becoming increasingly international in its representation. Results suggest that of the overall trauma literature, 36% of contributions come from authors outside North America. Likewise, among JTS publications over the first 14 years of circulation, 27% came from authors outside North America. More recent publication years reflect higher levels of international contributions for both sources. The majority of trauma research published over the 15-year span was in English. Implications for the field of traumatic stress research are discussed.
