J Rehabil Med 2019; 51: 149–150 EDITORIAL THE REAL IMPACT FACTOR OF JOURNAL OF REHABILITATION MEDICINE (JRM) AND JRM CLINICAL COMMUNICATIONS (JRM-CC) Impact is defined as: “the action of one object coming forcibly into contact with another” or “a marked effect or influence”. In scientific research, the impact of a journal is operationalized as the number of citations received during one year by articles previously published in the journal divided by the total number of articles published. The most commonly used indicators are the 2-year Impact Factor (IF) and the 5-year IF. Accordingly, the 2-year IF in 2018 for Journal of Rehabilitation Medicine (JRM) is the number of citations in 2018 (in all journals) to papers published in JRM during 2016 and 2017 divided by the total number of papers published in JRM during 2016 and 2017. The current 2- and 5-year IFs for JRM are 1.802 and 2.202, re- spectively. We expect the IFs to increase for 2018. In the Journal Citation Reports (JCR) ranking JRM currently ranks number 29 for the 2-year IF and 23 for the 5-year IF. For clinical journals, the 5-year IF is generally considered more appropriate, because clinical research has a slower turnover than more fundamental research. The highest numbers of citations generated by JRM papers occur in the third and fourth year after publication. As such, the 2-year IF underestimates the scientific impact of papers published in most general rehabilitation journals. Another prestigious ranking is published by Scimago (https:// www.scimagojr.com/journalrank.php). They use a 3-year period for papers to be cited in the year following this 3-year period. In addition, there are differences in what weight to give to Systematic Reviews, Letters to the Editor, Editorials, etc. The position of JRM in Scimago is more than satisfactory (Table I).  Many universities, hospitals, funding agencies and individual researchers consider the IF to be the main criterion to indicate the “quality” of journals or of authors. Publications in so-called “high-impact journals” are essential for researchers to make a Table I.

Although many authorities have criticized the use of the IF as the main criterion for quality it is still used worldwide. An important question is whether the rankings of IF by JCR or Scimago actually reflect the “marked effect or influence” of papers published in JRM. The Editors-in-Chief of JRM consi- der the IF as an inevitable indicator, not least for the scientific quality of the article. The fact that other scientists cite a study is of importance mainly for other researchers and not for the readers of a scientific journal, such as clinicians, patients, go- vernment, journalists, etc. However, for these readers, IFs do not adequately cover the concept of impact. We are therefore very excited that JRM has around 600 down- loads per day. Apparently people worldwide want to read our publications and apply the results in their daily work or daily life (Table II). The more than 200,000 downloads per year re- flect the “real impact factor” (RIF) of JRM and JRM-CC. The decision to become completely and immediately Open Access has certainly contributed immensely to this success. In contrast to most other journals, it is free of charge to read and download JRM articles. Our Lay Abstracts make studies more understandable for readers without a medical or scienti- fic background. The RIF will also strengthen areas of clinical importance that have few researchers. The Editors-in-Chief and Associate Editors promise to con- tinue to take all necessary steps to strengthen and improve the real impact of JRM, both for our authors and for our readers.
