Abstract

Introduction: The Hirsch index is not comprehensive for scientific outputs ranking. Its structure does not include some issues such as self-citation. Self-citation perhaps creates a scientometric complication. Using some scientometric indices such as h-index is inadequate for ranking scientists alone, and they perhaps turn to fake self-citations to increase their h-index over time. A new index (Ah-index) based on self-citation was introduced to scientific outputs ranking in this study.
Methods: The information system integration division (ISID) of Hamadan University of Medical Sciences was used to calculate the Ah-index on August 5, 2023 (n=445). Bootstrapping technique was used to estimate uncertainty, standard error and 95% confidence interval of Pearson’s correlation coefficient between the new index and h-index.
Results: This study shows that the correlation coefficient between h-index and Ah-index is 0.995 (C.I.95%: 0.993-0.997). The authors' rank according to the h-index differed from the Ah-index; where, scientists with high self-citations lost their position from the top of the list of authors according to our new indicator.
Conclusion: The findings of this study showed that by adjusting the self-citation of scientists, the position of the author in the list of authors would be changed and becomes fairer.
