分析引用四种主要综合医学期刊的报纸文章总数,并描述国家引用模式。定量内容分析。2008年至2015年期间14个国家的22份普通报纸的全文,收集自Lounge Nexis。这14个国家被分为四个地区:美国、英国、西方世界(英国以外的欧洲国家,以及澳大利亚、新西兰和加拿大)和世界其他地区(其他国家)。22家报纸对四种医学期刊(两种美国:NEJM和JAMA;两种英国:The Lancet和The BMJ)的引用。2008-2015年,英国和美国报纸每周引用四种分析的医学期刊中的一些期刊约三次(每周平均引用次数分别为3.2和2.7);其他西方国家的报纸每周引用一次(每周平均引用次数为1.1),世界其他国家的报纸每月引用一次(每月平均引用次数为1.1)。《纽约》的引用高于所有其他报纸(每周平均4.7)。分析表明,存在三个国家的引用模式,在每日出版物:美国报纸引用主要是美国期刊(70.0%的引文),英国报纸引用主要是英国期刊(86.5%),其余的分析媒体引用更多的英国期刊比美国的。《柳叶刀》是除美国和英国以外几乎所有西方国家媒体引用最多的期刊。多变量对应分析证实了国家模式,并表明,超过85%的引文数据的变异性保留在一个单一的新变量:国家层面。英国和美国的报纸更经常引用这四种分析的医学期刊,表现出对各自国家期刊的国内偏好;非英国和非美国的报纸表现出共同的国际引用模式。
To analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns. Quantitative content analysis. Full text of 22 general newspapers in 14 countries over the period 2008–2015, collected from LexisNexis. The 14 countries have been categorised into four regions: the USA, the UK, Western World (European countries other than the UK, and Australia, New Zealand and Canada) and Rest of the World (other countries). Press citations of four medical journals (two American: NEJM and JAMA; and two British: The Lancet and The BMJ) in 22 newspapers. British and American newspapers cited some of the four analysed medical journals about three times a week in 2008–2015 (weekly mean 3.2 and 2.7 citations, respectively); the newspapers from other Western countries did so about once a week (weekly mean 1.1), and those from the Rest of the World cited them about once a month (monthly mean 1.1). The New York Times cited above all other newspapers (weekly mean 4.7). The analysis showed the existence of three national citation patterns in the daily press: American newspapers cited mostly American journals (70.0% of citations), British newspapers cited mostly British journals (86.5%) and the rest of the analysed press cited more British journals than American ones. The Lancet was the most cited journal in the press of almost all Western countries outside the USA and the UK. Multivariate correspondence analysis confirmed the national patterns and showed that over 85% of the citation data variability is retained in just one single new variable: the national dimension. British and American newspapers are the ones that cite the four analysed medical journals more often, showing a domestic preference for their respective national journals; non-British and non-American newspapers show a common international citation pattern.
