Worldwide access to evidence-based mental health literature: how useful is PubMed in Anglo-Saxon and non-Anglo-Saxon countries?
The aim of this study was to verify the presence of cultural variety among the psychiatric journals available on PubMed, the major online tool for accessing literature. Data for analysis were taken from a survey of the world psychiatric journals indexed in Index Medicus 1999 (IM), the alphabetical list used by PubMed, and from the mean impact factor (IF) values of the journals. Approximately 80% of international psychiatric literature available on PubMed is published in Anglo-Saxon countries, especially in the USA (59.8% of the total). The widespread use of the English language (94.9% of all the journals) further stresses the dominance of the Anglo-Saxon cultural model, as do the mean IF values of Anglo-Saxon journals compared to non-Anglo-Saxon publications (3.252 vs. 1.693; P=0.0079). The under-representation of non-Anglo-Saxon cultural models on PubMed plays a negative role for bringing about a truly multicultural literature in psychiatry.
