Title

THE MORE PUBLICATION, THE HIGHER IMPACT FACTOR: CITATION ANALYSIS OF TOP NINE GASTROENTEROLOGY AND HEPATOLOGY JOURNALS

Pages

  0-0

Abstract

 Background: The impact factor (IF), as the most important criterion for journal’s quality measurement, is affected by the SELF-CITATION and number of publications in each journal.Objectives: To find out the relationship between the number of publications and SELF-CITATIONs in a journal, and their correlations with IF.Materials and Methods: SELF-CITATIONs and impact factors of nine top GASTROENTEROLOGY and hepatology journals were assessed during the seven recent years (2005-2011) through Journal Citation Reports (JCR, ISI Thomson Reuters).Results: Although impact factors of all journals increased during the study, five out of nine journals increased the number of publications from 2005 to 2011. There was an increase in SELF-CITATION only in the journal of HEPATOLOGY (499 in 2005 vs. 707 in 2011). Impact factors of journals (6.5±3.5) were positively correlated with total number of publications (248.6±91.7) (R: 0.688, P<0.001). Besides, the SELF-CITATION rate (238.73±195.317) was highly correlated with total number of publications in each journal (248.6±91.7) (R: 0.861, P<0.001). On the other hand, impact factor without SELF-CITATION (6.08±3.3) had a correlation (R: 0.672, P<0.001) with the number of published items (248.6±91.7).Conclusions: The number of articles and SELF-CITATION have definite effects on IF of a journal and because IF is the most prominent criterion for journal’s quality measurement, it would be a good idea to consider factors affecting on IF such as SELF-CITATION.
