■本研究旨在确定高影响力的决定因素,按影响因子(IF)和特征值得分衡量,耳鼻喉科杂志。
■“耳鼻咽喉科”期刊的文献计量数据收集自期刊引文报告(JCR)数据库。2009-2020年,我们收集了归一化特征值得分,5年IF,即时性指数,来自期刊自引的IF分数,已发表的可引用文章的比例和数量,和总引用数。High-IF和-Eigenfactor期刊被认为是每年该指标前四分位数内的期刊。
■高IF和-Eigenfactor耳鼻喉科期刊显示较高的5年期IF,即时性索引,和无自引的IF(所有年份p<.05),包括按特征值排序的总引文计数和可引用文章(所有年份p<.05)。耳鼻喉科IF与同年的5年IF和即时性指数相关(所有年份p<0.05)和前几年(所有年份p<0.05;2017-2018年p<0.05;2009-2016年p>0.05)。特征因子与5年IF相关,总引文计数,以及同一年(所有年份p<0.05)和前几年(2013-2018年p<0.05)内的可引用文章。多元线性回归显示,5年IF(2009-2018年p<0.05)和前2年的即时性指数(2017-2018年p<0.05;2009-2016年p>0.05)预测了2019年IF。同样,5年IF,总引文计数,和可引用的文章(2013-2018年p<0.05)预测了2019年的特征因子得分。
■持续发表有影响力的文章是高IF和特征值得分的主要驱动因素。特征因子得分反映了对耳鼻咽喉科期刊的独特评估;与按IF进行排名相比,按特征因子得分对耳鼻咽喉科期刊进行排名显着改变了期刊排名。

UNASSIGNED: This study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals.
UNASSIGNED: Bibliometric data of \"otorhinolaryngology\" journals were collected from the Journal Citation Reports (JCR) database. For the years 2009-2020, we collected normalized Eigenfactor score, 5-year IF, immediacy index, fraction of IF from journal-self citation, proportion and magnitude of published citable articles, and total citation counts. High-IF and -Eigenfactor journals were considered those within the top-quartile of that metric each respective year.
UNASSIGNED: High-IF and -Eigenfactor otolaryngology journals displayed higher 5-year IFs, immediacy indexes, and IF without self-citation (p < .05 for all years) including total citations counts and citable articles when ranked by Eigenfactor (p < .05 for all years). Otolaryngology IF correlated with 5-year IF and immediacy index within the same year (p < .05 for all years) and from previous years (p < .05 for all years; p < .05 for 2017-2018; p > .05 for 2009-2016). Eigenfactor correlated with 5-year IF, total citation counts, and citable articles within the same year (p < .05 for all years) and previous years (p < .05 for 2013-2018). Multilinear regression revealed that 5-year IF (p < .05 for 2009-2018) and immediacy index from the prior 2 years (p < .05 for 2017-2018; p > .05 for 2009-2016) predicted 2019 IF. Similarly, 5-year IF, total citation counts, and citable articles (p < .05 for 2013-2018) predicted 2019 Eigenfactor score.
UNASSIGNED: Sustained publication of impactful articles is the dominant driver of high IF and Eigenfactor score. Eigenfactor score reflects a unique evaluation of otolaryngology journals; ranking otolaryngology journals by their Eigenfactor scores significantly alters journal ranking compared to ranking by IF.
UNASSIGNED: NA.
