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.
