The aim of this study was to quantify changes in the national contributions to research related to posttraumatic stress disorder (PTSD) from 1983 through 2002. Using the Web of Science database (Thomson Scientific, Philadelphia, PA), we classified articles according to the year of publication and the country of the authors. The number of publishing countries increased from 7 between 1983 and 1987 to 39 between 1998 and 2002. Meanwhile, the U.S. output share declined from 87.6% in the first period to 62.4%. Although the number of countries publishing on PTSD has steadily increased, research is still dominated qualitatively and quantitatively by developed countries. These findings suggest a growing international acceptance of this diagnostic category. However, the immaturity of PTSD research is demonstrated by the concentration of publications in a few countries.
Introduction: Conditional risk for PTSD is the probability of developing PTSD after exposure to trauma; and is influenced by gender, socioeconomic status and type of trauma. Aims: To summarize data on conditional risk for PTSD in the general population through a systematic review and metaanalysis. Methods: Our search included 4 databases, references from selected articles, cited-reference tools, and contact with 30 researchers. We obtained combined measures of conditional risk secondary to any trauma, death of close person and sexual violence. Results: Conditional risk secondary to any trauma was 8.72%. (Women: 13.3%, men: 4.3%); secondary to death of close person was 7.7% (women: 16%, men: 3.3%); and secondary to rape was 26.7% (women 32.9%, men: 37.1%). Discussion: The present metaanalysis is relevant for determining traumatic events highly associated with PTSD and studying possible risk factors and PTSD physiopathology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
