This article concerns the question of journal impact factor and other bibliometric indicators made available by the Institute for Scientific Information in their Journal Citation Report for 1996. The impact factors of journals within the subject category 'substance abuse' are listed along with total citations, immediacy indices, and cited half-lives. The relationship between cited and citing journals is discussed with the main focus on the data available for Alcohol and Alcoholism. Some of the problems and limitations of bibliometric measures of productivity are dealt with, especially when these are used to evaluate the work of individual scientists. Although bibliometric measures are easy to compute, they become difficult to interpret, such as when dealing with collaborative research and the problem posed by multiple authorship. The need to adjust impact factors and citation counts for the number of co-authors in a paper becomes important when credit has to be attributed to one individual from a multi-author paper. This is often necessary in connection with grant applications and when making decisions about academic promotion and tenure. The impact factor of Alcohol and Alcoholism has increased steadily over the past 5 years, even after adjusting for the number of self-citations, which resulted in an even greater increase in impact. However, the impact factors of substance abuse journals are generally low, compared with disciplines such as immunology, genetics, and biochemistry. Some suggestions are made for increasing the impact factors of substance abuse journals if this is considered necessary. But instead of paying attention to the impact factor of a journal, scientists should give more consideration to the speed and efficiency of the editorial handling of their manuscripts and particularly to the quality and timeliness of the peer review.

A computerized search of literature on sport for disabled persons referenced in the MEDLINE (Index Medicus) and the SPORTDiscus (Sport International Resource Center SIRC) databases yielded 253 records published during the past 15 years. An analysis of these records by disability, age, and scientific discipline indicated that (a) publications related to physiology were most frequent (41%), followed by publications related to psychology (29%);(b) 58% of all records had wheelchair users as subjects;and (c) children were exclusive subjects in 10% and females in less than 2% of the records reviewed in this search.

Study objective: We sought to examine how a cohort of published emergency medicine research is cited in scientific journals. Methods: Data were collected on all research submitted to the 1991 Society for Academic Emergency Medicine meeting and subsequently published. Outcome measures included all citations of these studies found in journals listed in the Science Citation Index, as well as the impact factors (citations per manuscript per year) of citing journals. Results: Two hundred four of the 493 submitted studies were published and met study entry criteria;the average article was cited 2.04 times a year during the study period. Twelve percent were never cited, and 39% were cited only once or twice. Thirty percent were published in non-emergency medicine journals, and these were cited at least twice as often (and by almost 3 times as many journals) as apparently similar studies published in emergency medicine journals. The percentage of studies never cited by anyone was about threefold higher when published in emergency medicine journals. Forty-two percent of the citations of research published in emergency medicine journals came from within the specialty. Emergency medicine journals provided only 16% of the citations of emergency medicine research published in non-emergency medicine journals because these studies were cited 3 times as often by authors in other disciplines. Rejection of research for presentation at the meeting did not predict the number or quality of citations or citing journals. Conclusion: Research submitted to the Society for Academic Emergency Medicine meeting and subsequently published is cited about as often as the average scientific journal article but receives more impact, is cited more widely, and is more likely to he cited by a broader range of authors when published by non-emergency medicine journals. The ability of emergency medicine journals to compete with larger non-emergency medicine journals for their larger audiences may help sha
