JOURNAL IMPACT FACTOR
What is Journal Impact Factor? • Journal impact factor (JIF) is a measure of the quality of a journal. • JIF is the average number of times that articles published in a specific journal in the two previous years were cited in a particular year. • Mathematically, JIF = Number of citations received by a journal in a year say 2010 to articles published in 2008 and 2009 Number of citable articles published by the journal in 2008 and 2009
Where to find Journal Impact Factors • Journal Impact Factors are found in Journal Citation Reports (JCR) which is a unique database used to determine the relative importance of journals within their subject categories.
Four Important Facts About Journal Impact Factor • 1. Not all journals have impact factors. Journals must be indexed in Web of Science to have an impact factor. • 2. A journal has only one impact factor, but it may be listed in more than one category • 3.A journal impact factor should not be looked at in isolation, but in comparison to other journals in the same category • 4. Impact factors vary across disciplines
Scenario • A researcher recently got his article published in the British Medical Journal (BMJ) which has an impact factor of 14.093 • Question • Can the BMJ be rated as a good journal based on its impact factor?
Answer • To say that BMJ has an impact factor of 14.093 is not really meaningful, it is more useful to say that BMJ’s impact factor ranks sixth of 153 journals in the field of General and Internal Medicine or to compare its impact factor of 14.093 with the aggregate impact factor for its field (General and Internal Medicine): 3.919
Recommendation • It is therefore recommended that the impact factor of a journal is not looked at in isolation. Rather, the impact factor of a journal should be compared to the impact factors for other journals within the same subject category.
Relevance of Journal Impact Factor • Journal Impact Factor can help researchers: • 1. identify journals in which to publish their research findings • 2. identify journals relevant to their area of research • 3. confirm the status of journals in which they have published
