B- Impact factor and citation performance

Finardi U. Correlation between Journal Impact Factor and citation performance: an experimental study. Journal of Informetrics 2013;7(2):357-370
(doi: 10.1016/j.joi.2012.12.004)

This article studies how the correlation between the Journal Impact Factor and the (time-weighed) article Mean Received Citations (intended as a measure of journal performance) has evolved through time. It focuses on a sample of hard sciences and social sciences journals from the 1999 to 2010 time period. Correlation coefficients (Pearson's Coefficients as well as Spearman's Coefficients and Kendall's τα) are calculated and then tested against several null hypotheses. The results show that in most cases Journal Impact Factors and their yearly variations do not display a strong correlation with citedness. Differences also exist among scientific areas.
