Abstract

This study reports on the yearly rate of journal self-citation (JSC) in sport sciences, how it changes over time, and its association with journal impact factor (JIF). Citations made by all 87 journals in “sport sciences” from 2013 to 2022 were extracted, as was their 2022 JIF. JSC rates were calculated using a Poisson distribution method. A mixed-effects negative binomial regression examined changes in yearly JSC rates over time. The association between average JSC rates and JIF were compared using a negative binomial regression. The median JSC rate was 6.3 self-citations per 100 citations. JSC rates are increasing in sport sciences by ~ 10% per year (incidence rate ratio [IRR] = 1.1, 95% CI 1.1–1.2; trivial effect). There was a significant negative association between JSC rate and JIF (IRR = 0.9, 95% CI 0.9, 1.0; trivial effect). Contrary to observations made in prior literature examining broader disciplines, the increasing JSC rate in sport sciences may be attributed to the growing maturity of this novel discipline. As sport-science topic areas become more established and appear in discipline specific journals, more JSCs may occur due to an increasing body of literature in these journals. The negative association between JSC rate and JIF may be due to specialized and less visible journals having a naturally lower JIF, as their impact is confined to a narrower field.

体育科学的期刊自引趋势：2013 至 2022 年学科期刊分析

本研究报告了体育科学领域期刊的年度自引率（JSC）、JSC 随时间的变化情况及其与期刊影响因子（JIF）的关系。研究提取了 "体育科学 "领域所有 87 种期刊在 2013 年至 2022 年期间的引用情况，以及它们 2022 年的 JIF。采用泊松分布法计算 JSC 率。混合效应负二项回归检验了每年的 JSC 率随时间的变化。使用负二项回归比较了平均 JSC 率和 JIF 之间的关联。JSC率的中位数为每100次引用中有6.3次自我引用。体育科学领域的自引率每年增长约 10%（发生率比 [IRR] = 1.1，95% CI 1.1-1.2；微不足道的影响）。JSC率与JIF之间存在明显的负相关（IRR = 0.9，95% CI 0.9，1.0；微不足道的影响）。与之前研究更广泛学科的文献所观察到的情况相反，体育科学中不断增加的 JSC 率可能归因于这门新兴学科的日益成熟。随着体育科学主题领域越来越成熟，并出现在特定学科期刊上，这些期刊上的文献也会越来越多，因此可能会出现更多的 JSC。JSC率与JIF之间的负相关可能是由于专业期刊和知名度较低的期刊的JIF自然较低，因为它们的影响仅限于较窄的领域。

期刊介绍： Scientometrics aims at publishing original studies, short communications, preliminary reports, review papers, letters to the editor and book reviews on scientometrics. The topics covered are results of research concerned with the quantitative features and characteristics of science. Emphasis is placed on investigations in which the development and mechanism of science are studied by means of (statistical) mathematical methods. The Journal also provides the reader with important up-to-date information about international meetings and events in scientometrics and related fields. Appropriate bibliographic compilations are published as a separate section. Due to its fully interdisciplinary character, Scientometrics is indispensable to research workers and research administrators throughout the world. It provides valuable assistance to librarians and documentalists in central scientific agencies, ministries, research institutes and laboratories. Scientometrics includes the Journal of Research Communication Studies. Consequently its aims and scope cover that of the latter, namely, to bring the results of research investigations together in one place, in such a form that they will be of use not only to the investigators themselves but also to the entrepreneurs and research workers who form the object of these studies.
