BJOG: An International Journal of Obstetrics and Gynaecology now has an impact factor of 5.051, ranking it 4th out of 79 journals in the OBGYN category, according to the 2016 Thomson Reuter Journal Citation Report® (JCR). This is a significant increase from the 2015 impact factor and BJOG now ranks above a number of competitor journals.
The impact factor is the average number of citations an article in a journal receives, and is used as a measure of the quality of papers published by a journal. It is calculated by the number of citations received in the JCR year by articles published in that journal during the two preceding years, divided by the total number of articles published in that journal during the two preceding years. Thomson Reuters publish the report annually and draw data from thousands of journals across a number of disciplines.
Professor Khalid Khan, BJOG Editor-in-Chief, said:
“It is fantastic that BJOG’s impact factor is now over 5 as this is a significant milestone for the Journal. We have a brilliant team of editors who ensure we publish the best papers in our specialty, and continue to enhance our content with commentaries and digital features.”
BJOG is an editorially independent publication owned by the Royal College of Obstetricians and Gynaecologists, publishing original, peer-reviewed work in all areas of obstetrics and gynaecology from around the world.
Professor Mary Ann Lumsden, Senior Vice President for Strategic Development at the RCOG said:
“I am delighted to see the Journal go from strength to strength, and it continues to provide access to high quality research for our membership, and the specialty as a whole and this increase will encourage even more high quality submissions.”
