Impact factors in nursing journals

Journal impact factors (IFs), a measure of citation frequency, are published annually in Journal Citation Reports (JCR). Journal IFs, although controversial because of the uses to which they have been put in academic arenas, remain a metric about which nurses should be informed. This paper discusses key issues in the controversy, explains how IFs are computed, and presents historical and 2009 IF data for nursing journals. The number of nursing journals indexed in JCR has grown from 35 in 2004 to 74 in 2009. The journals currently indexed are diverse in terms of focus (practice vs research), specialty areas, and country of publication. The median IF score for nursing journals (0.91 in 2009) is similar to that for several other health care categories. Given the controversies surrounding IFs, it may be useful for nurses to play a more active role in furthering the debate by undertaking research relating to IFs, including studies of how they affect nurses' scholarly pursuits and publication decisions.
