Citation scores (CS) are traditionally used to measure the impact of scientific publications. Altmetric Attention Scores (AAS), in contrast, consider the digital dissemination of articles across social media platforms to track their audience reach. In this cross-sectional study, we aimed to determine the correlation between AAS and CS in 12 high-impact-factor journals in the category of 'Clinical Medicine'.
The 12 journals with the highest 2023 journal impact factor (published in June 2024), four each in General and Internal Medicine, General Surgery, and Anaesthesia, were included. Articles published in final version between January 1 and December 31, 2021 were selected, and up-to-date AAS and CS for each article were obtained on July 2, 2024 from Dimensions (https://app.dimensions.ai/discover/publication). Spearman's rank order correlations (ϱ) were used to assess the strength of the association between AAS and CS.
A total of 5193 outputs (2747 in Medicine, 1345 in Surgery, and 1101 in Anaesthesia) were analysed, with median (interquartile range) AAS and CS of 37 (10-157) and 16 (6-52), respectively. Medicine journals had the highest AAS and CS (124 [47-384] and 28 [8-113]), followed by Anaesthesia (12 [5-27] and 12 [5-24]) and Surgery (9 [2-24] and 11 [4-27]), respectively. There was a moderate positive correlation between AAS and CS overall (ϱ=0.589), with a moderate correlation for Medicine (ϱ=0.681) and Anaesthesia (ϱ=0.427) and a weak correlation for Surgery (ϱ=0.354) (all P<0.0001).
Altmetric Attention Scores correlated with citation scores, suggesting that audience engagement via social media can influence the future impact of publications and their citation scores.
传统上，引用分数（CS）用于衡量科学出版物的影响力。相比之下，替代计量关注度分数（AAS）则考虑文章在社交媒体平台上的数字传播情况，以追踪其受众范围。在这项横断面研究中，我们旨在确定12本“临床医学”类别高影响因子期刊的AAS与CS之间的相关性。
纳入2023年期刊影响因子最高的12本期刊（于2024年6月出版），普通内科、普通外科和麻醉学领域各4本。选取2021年1月1日至12月31日期间发表的最终版本文章，并于2024年7月2日从Dimensions（https://app.dimensions.ai/discover/publication）获取每篇文章的最新AAS和CS。采用斯皮尔曼等级相关系数（ϱ）评估AAS与CS之间关联的强度。
共分析了5193篇产出（医学领域2747篇、外科领域1345篇、麻醉学领域1101篇），AAS和CS的中位数（四分位间距）分别为37（10 - 157）和16（6 - 52）。医学期刊的AAS和CS最高（分别为124 [47 - 384]和28 [8 - 113]），其次是麻醉学期刊（分别为12 [5 - 27]和12 [5 - 24]）以及外科学期刊（分别为9 [2 - 24]和11 [4 - 27]）。总体而言，AAS与CS之间存在中度正相关（ϱ = 0.589），医学领域（ϱ = 0.681）和麻醉学领域（ϱ = 0.427）为中度相关，外科学领域为弱相关（ϱ = 0.354）（所有P < 0.0001）。
替代计量关注度分数与引用分数相关，这表明通过社交媒体的受众参与度会影响出版物的未来影响力及其引用分数。
