Abstract:
Background: Thomson Institute for Scientific Information's journal impact
factor, the most common measure of journal status, is based on crude
citation counts that do not account for the quality of the journals where
the citations originate. This study examines how accounting for citation
origin affects the impact factor ranking of dermatology journals.
Methods: The 2003 impact factors of dermatology journals were adjusted by a
weighted PageRank algorithm that assigned greater weight to citations
originating in more frequently cited journals.
Results: Adjusting for citation origin moved the rank of the Journal of the
American Academy of Dermatology higher than that of the Archives of
Dermatology (third to second) but did not affect the ranking of the highest
impact dermatology journal, the Journal of Investigative Dermatology. The
dermatology journals most positively affected by adjusting for citation
origin were Contact Dermatitis (moving from 22nd to 7th in rankings) and
Burns (21st to 10th). Dermatology journals most negatively affected were
Seminars in Cutaneous Medicine and Surgery (5th to 14th), the Journal of
Cutaneous Medicine and Surgery (19th to 27th), and the, Journal of
Investigative Dermatology Symposium Proceedings (26th to 34th).
Limitations: Current measures of dermatology journal status do not
incorporate survey data from dermatologists regarding which journals
dermatologists esteem most.
Conclusion: Adjusting for citation origin provides a more refined measure
of journal status and changes relative dermatology journal rankings.
